Abstract
The system and method for controlling the running of trains in track network can predict events in fuzzy network and prompt the dispatcher to provide information or take action as the function of the predicted events. The track network is divided to have at least one control area, and one dispatcher is designated to control the running of trains inside the control area.
Description
Technical field
The present invention relates to the system and method dispatched according to abnormal condition.
Background technology
The application requires in the rights and interests of the U.S. Provisional Application 60/449,849 of submission on February 27th, 2003.
Because the complex nature of the problem of the multiple row train of limited resources is competed in control simultaneously, the time-table of overall rail network (that is, nationwide) is difficult to developing on the basis in real time.Rail network generally includes tens thousand of miles track, thousands of locomotive engines and hundreds thousand of joint freight car.At any one time, all have thousands of trains and the track of safeguarding vehicle competition limited amount.The service that is scheduled for management self-consistentency in this environment, railway uses the technology of " dividing and rule " that rail network is divided into the several Control zone, and for each control area produces a local operational plan, thereby on numerous scheduling resources, share the complexity of scheduling problem.Assign the train scheduling personnel for these controles area, their responsibility is according to the corresponding operational plan of this control area, to make train and equipment current reposefully in this control area with the delay of minimum.Control a plurality of scheduler of a predetermined portions of railway separately, be configured for example based on the railway dispatching system of modern computer.
In this environment, expect that this scheduler solves complicated operation problem in real time.For example, scheduler must be considered limited track resource, the length of train, and the length of spendable by-track, the point of train junction and process is to the maintenance request of track time (track time), availability of locomotive or the like.Scheduling may become a urgent environment, though safety measure and transmission system are arranged, the error of scheduler still may be caused deaths and can be caused the serious reduction of railway performance continually.In order to alleviate this burden, the Computer Processing dispatching system is used to help scheduler " to see " their control area, and external system provides a flow of information that continues about railroad conditions.This flow of information comprises time-table, and the customer consignment item is safeguarded timetable, and train is formed (train consist), the track fault, and car group personal information, weather and other directly influence the dynamic factor of the daily running of railway.Along with the computerization of more system, scheduler receives more accurate information; Yet the quick growth of quantity of information makes that scheduler is difficult to clearly make a policy in real time and take action more.Over-burden owing to information, and the decision structure of typical dispatching system, and scheduler lacks vision for their action to the influence of whole piece train path or whole piece railway.When rows of cars passed through its route on railway, several train scheduling persons will " contact (touch) " this train.Owing to limited information of going deep into and predetermined decision structure, make that inevitably the activity of a scheduler (though may be suitable in the environment in this scheduler zone) possibly can't provide best whole train operation.
If do not have fully to understand complicated neighboring region or arbitrary particular moment train to the relative worth of railway, even in the zone of scheduler oneself control, they do not possess the condition of making the optimal scheduling decision-making yet. similarly, scheduler can guide train to enter its neck and connect the zone, but find, the result is that whole railway is more congested. in this case, correct decision-making should be to make train rest on the available by-track in this scheduler zone or have in the station (yard) of capacity sufficient, and to wait for until obstruction and alleviate or eliminates. the another kind of issuable situation of enough information that the scheduler shortage is used for making the relevant global network of best decision is, wherein the ordered series of numbers train need pass through a crowded track zone, and there are not enough available tracks to hold these trains simultaneously herein. this scheduler which row train of having to promptly make a strategic decision " keeps to the side " (being shelved on the available by-track) so that allow other train pass through. in dispatch environment now, because lacking when a control area runs to the control area that a neck connects, coordinates by train, therefore there is not insufficient information about the relation of all other trains in rows of cars and other control area, yet so that scheduler is made best decision-making for railway integral body., if the needed information that rolls up of the management in the system-wide is all made and makes scheduler to use, then increase the complexity of scheduling feature probably, it is surpassed by the current method institute energy safety based on manpower, Guan Li degree reliably.
Current, can think that scheduler is short-sighted to the observation in its railway zone of controlling.The information in their control area is only observed and handled to scheduler, and seldom or not have the vision to adjacent areas or the operation of rail network single-piece.Similarly, scheduler is the decision center in his or his zone.Current dispatching system is carried out control according to each scheduler about the decision-making of the rail network of each fraction simply.When clashing between the operation of the object on the track (for example train, safeguard vehicle, measuring vehicle etc.) and the available track resource limit (for example the track of limited amount, the track that can not serve, near the consideration of the safety of the service personnel the active track), the control scheduler is expected at and solves described conflict under the situation that does not almost have pre-determined vision or warning.
For example, if railway is being submitted to responsible scheduler to the request of safeguarding a part of rail network, this scheduler need be by changing predetermined operational plan to make things convenient for this maintenance so.The operation of the train of described operational plan device plan in should the zone usually, when so operating, scheduler is not provided the input based on the operational plan device of computer processor.If this scheduler has interrupted the execution of operational plan to the special scheduling of described maintenance, until safeguarding beginning, operational plan just is affected so.And when the influence of the maintenance of unscheduled is finally understood by operational plan and adapted to, may deletrious more further influence may take place for operational plan so.
Summary of the invention
In this application, several aspects that operate in of train make moderate progress.In one aspect of the invention, increased between scheduler with based on the communication between the planning system of computer processor.In another aspect of the present invention, on the planning system of transferring to by the responsibility of scheduler execution traditionally based on computer processor always.Of the present invention aspect another,, transmit information and feed back to scheduler from the scheduler transmission with convenient for scheduler provides mutual demonstration.
Technique effect is, can will use together based on the module and the centralized operational plan device of computer processor and the generator of making a strategic decision, bearing the many conventional responsibility of scheduler, thereby allow scheduler can manage the conflict that operation and solution took place more effectively by the train of its control area.
By the reading to accompanying drawing and following detailed description, advantages associated of the present invention will be apparent for those of ordinary skills.
Description of drawings
Fig. 1 is the simplicity of illustration that is provided with being divided into the one embodiment of the invention that the mode of the rail network of each control area uses.
Fig. 2 is the automatic dispatching person's of Fig. 1 the functional block diagram of simplification.
The specific embodiment
In one aspect of the invention, by being coupled to one away from the decision center of each scheduler, and therefore scheduler is alleviated the efficient of coming out to improve a plurality of trains of scheduling in the network railway system from the operational plan decision-making of complexity. the substitute is, more effectively utilized scheduler to provide information to dispatching system based on computer processor, this dispatching system provides an operational plan of more optimizing for the whole network railway system. in addition, can advantageously utilize scheduler as soon as possible information is provided to the operational plan process, thereby be convenient to automatically performing of best plan and conventional scheduler function, and do not need scheduler to assess various complex situations: this not only can influence the operation by this scheduler control area train, and can influence the operation by the train of whole rail network.
The exploitation of the plan of process rail network running train is subjected to the restriction of many constraint conditions, and uses usually and finish based on the planning system of computer processor.Typically, the operational plan device provides the operational plan in the whole network scope, and a group scheduling person has been assigned according to overall operational plan management task to Train Control in its control area separately.The present invention is intended to change the traditional coupling between operational plan function and the scheduling feature.
Rail network is divided into a plurality of controles area traditionally, assigns a scheduler to control the track resource with the tubulature wagon flow and in scheduler control area separately for each control area.The application has kept the control to train and the resource that is associated with scheduler; But utilize the best of the purpose of suitable whole railway the plan facility should control.Use usually place in current system, The present invention be directed to centralized automated decision-making center by the non-centralized decision center of scheduler management, it provide automatic, optimized plan information to scheduler with the resource of management in control area separately.In other words, current most real time execution decision-makings of being made by scheduler will be alleviated by the decision-making that computer processor is made on higher railway enterprise or whole network level according to the operational plan device of optimizing based on computer processor.In case the realization this point, scheduler can be absorbed in the time this plan of execution and handle abnormal condition.
Fig. 1 for example understands one embodiment of the invention.Overall situation rail network 105 can be divided into one or more controles area 100 (100A-100C), and each control area has a scheduler 110 (110A-110C), and this scheduler is assigned manages by its operation of the train of control area 100 separately.Centralized operational plan device 120 is according to the input that receives from railroad information support center 130, for overall rail network 105 provides based on network operational plan.The out of Memory that railroad information support center 130 provides the information that relates to the track resource and is suitable for planning the use of this resource.The information that is fit to can comprise the departure place of train and moving position (activity location) and the important INTRM intermediate point in destination and this train circuit.This information can comprise that also the target of departure place and destination and important INTRM intermediate point sets out and the time of advent.This information can also be provided for the default composition data (default consist data) of preliminary plan, until can obtaining data more specifically, and is provided as the default cost function (default cost function) of each row train exploitation.
Centralized operational plan device 120 is for the resource generating run plan in the rail network 105, and with this plan person 140 that offers the automatic dispatching.Operational plan device 120 also can receive more new data from automatic dispatching person 140 in the operational plan implementation, and can upgrade current operational plan.Automatic dispatching person 140 provides operational plan so that they manage train resources in control area 110 separately for each scheduler 110.
Can use the computer-readable medium that the has computer-readable code person 140 that realizes the automatic dispatching, carry out described computer-readable code by special use or general computer.Automatic dispatching person 140 via the communication link 150-that is fit to for example the train 102 on vehicular telephone, satellite or sideband signaling and the train network communicate.
Even in this new example, the part responsibility of scheduler will remain unchanged, yet these responsibilities will be supported the plan of optimization, rather than at large directly carry out this plan.Scheduler will continue issue or approval issue operation authority (movement authority) and track limiting condition, the scheduling road activity (way activity) maintenance and with car group personnel, station handler and other railway personnel communicate. still, these all activities will be consistent with the operation planning of the optimization that is used for railway. when scheduler will depend on the operational plan device when solve optimizing the complicated problems of train operation, scheduler will be absorbed in plan and the outer required necessary data of abnormal condition of Identification Scheme that optimization is kept in input energetically. for example, if rows of cars (are for example being carried out predetermined work activities, loading and unloading the compartment) and the train consist personnel notify scheduler they wish to obtain other delay, so this scheduler can be provided to deferred message in the operational plan device system on the basis of expection via automatic dispatching person 140, and allow centralized operational plan device 120 to assess its influences to based on network operational plan. in prior art systems, the operational plan device does not receive the information about the delay of expection usually, therefore the operational plan device only can provide aftereffect that (if providing really) is provided for postponing after this delay has taken place. by the notice early of predicted delay is provided, the operational plan device can be considered desired delay, and alleviate even avoid its influence the remainder of operational plan. subsequently, according to updated information, the operational plan device can correspondingly be adjusted the operation of other train. notices in current dispatch environment, do the decision-making of many parts to adapt to this additional delay (allow train passage thereafter or persist train etc.) with needing scheduler, and because the information about all other trains of scheduler is limited, those decision-makings may not be best for the optimization operation of railway.
Determine the optimized operation plan for train in advance, and for scheduler provides auto-mechanism to carry out this plan, finally can change the focus of scheduler into from the real-time response interaction with train operation is the role of plan optimization and exception handling more.In this new example, the role of scheduler passes on abnormal condition known or expection to operational plan, thereby submits necessary information before train is scheduled so that conflict and minimize.Otherwise, be coupled in the dispatching system of operational plan device, can reduce customary task and information is offered scheduler to increase efficient and to alleviate workload.The application's characteristics are that actv. uses previous plan the scheduler decision-making is reduced to the degree that only just needs scheduler to interfere on unusual basis.
In another aspect of the present invention, the amount of the information of transmitting between automation plan system and scheduler and type have increased.The part that some past of planning process are manually finished by scheduler can automatically have been carried out by planning system before the generating run plan now.For example, by automatically making things convenient for the plan that strengthens for operational plan device 120 information provisions from railroad information support center 130, so that be used for the maintenance that the train journey specification of operational plan (train trip specification) automatically reflects traditional train worksheet data (train sheet data) (via electronic notification and customer data input), wherein railroad information support center 130 becomes incident (train consist event) (for example entrucking (pickup) with train groups, car group personnel change, the locomotive destination) is associated with the train activity of the plan that in length of the halt, occupies the track resource.This information can automatically provide from external electronic system, does not need scheduler that any action is arranged.
In another aspect of the present invention, dispatching system of the present invention can provide the information except that traditional operational plan to fulfil their obligation to help scheduler. and Fig. 2 for example understands an embodiment of system of the present invention, plan operation and relevant resource according to train, the several modules that constitute automatic dispatching person 140 are worked together with the generation of predicted events. assess by automatic dispatching person 140 in assessment operational plan module 200 by the operational plan that operational plan device 120 provides. according to current operational plan and other factor that is fit to, assessment operational plan module can be predicted the generation of desired incident, described suitable factor comprises historical train performance, train characteristic, the track data bank, topological database, car group personal information, working rule and policy and Weather information. the automatic dispatching person can produce a task list according to the incident of prediction, be used for the specific action that should take in task list producing device module 220 sign scheduler institute. historical train performance can comprise can the following performance of aid forecasting train suitable factor, comprise for train carry out particular type activity the working space (for example, petrol service station) configuration, according to type of train, direct of travel, the configuration of the working space of station that is associated or specific train, and the configuration that transmits (routing) parameter (such as the automatic recovery of authority generation) automatically. the factor that is fit to of train characteristic comprises: type, the limiting factor of power and physics (for example, the height that prolongs). except that the quantity and configuration of track, other factor that is fit to also comprises in the track data bank: station capacity and through the workflow of station, the train number of time per unit for example. car group personal information can comprise the performance in specific car group personnel or particular schedule person's past. the factor that is fit to of car group personnel performance can comprise: type of train, trip distance on time and track section, and with the quantity that deviates from mutually of operation of plan. the statistical information that is fit to the assessment scheduler comprises: by the track hop count amount of scheduler control, the pattern of the track under scheduler control, in the zone according to the train quantity of track pattern, and the quantity that deviates from mutually with operational plan.
Assessment operational plan module 200 is also considered the interdependent property of different trains.For example, the two or more trains of specific action need such as the situation of information exchange (block swap), non-productive operation and cancellation midway or the participation of resource.Assessment operational plan module 200 is known needs action related between the train, and takes anyly may influence in the related train at least one action the time in this scheduler, and the notice and the warning scheduler of this related action can be provided for scheduler.
Task list generator module 220 provides task list via interactive display module 250 for scheduler.Task list generator module 220 can point out scheduler to take the action of wanting, and solicited message provides suitable form and help scheduler in other required responsibility.In monitoring operational plan execution module 210, can monitor the generation of predicted events, and can point out scheduler to take other specific action to respond the generation of the predicted events in task list producing device module 220.It is exactly the generation of the task list of the action that should be taked by the scheduler that interactive display module 250 provides that the prompting scheduler is taked a suitable mode of specific action.This dispatching system can be followed the trail of scheduler subsequently and finish identifying of task in the task list of monitor task list block 230.For example, can identify a task, be that train create a new operation authority in current operation authority near stopping limit with the prompting scheduler.This has been avoided stopping train to wait for the operation authority.Any action of being taked at interactive display module 250 by scheduler can offer operational plan device 120 so that consider in the next operational plan generation cycle.Described module can be included in the computer readable program code in the computer usable medium of suitable computing machine, the computing machine of all general-duties in this way of described computing machine or special-purpose purpose.
In another aspect of the present invention, in interactive display module 250, can provide dynamic task list for scheduler.Dynamic task list has not only been specified will be by the performed task of scheduler, and automatically the scheduler telltale is associated with the quantitative data input form that is fit in the form generator module 260.For example, the automatic dispatching system can predict the operation by the train of a control area, and can predict when the operationral report about the position of train should be received in assessment operational plan module 200.If do not receiving operationral report by monitoring in a certain specified time that the operational plan execution module is determined, then dispatching system can point out scheduler that a delay report is provided or via the source of form generation module 260 sign train delays.When producing delay report, delay report can be filled in advance with known information.Submit to reason that delay report, operational plan can utilize delay with the operational plan of revising the whole network scope and consider any other delay of being expected equally by the prompting scheduler.Therefore, before really being subjected to postponing to be unfavorable for operational plan, can consider a possible delay with its influence.
Information padding data input form known to when in another aspect of the present invention, task list can produce with it dynamically.Therefore, according to the movable of train or by the obstructing event that scheduler identified in the past, can use possible reason to fill in delay report in advance.Therefore, when the required task of the condition of reminding current train of scheduler and track resource, the operational plan device receives the required information of optimal plan that generates automatically.
In another aspect of the present invention, if this train can not pass its route in the time of expection a part then can detect delay.For example, on one section track, be that the basis can identify delay individually with the required time of passing.For one section given track,, can predict walking the time of estimation according to the Train Schedule that does not have opposition.If this train can not be walked given track section, according to the information of automatic dispatching person previously known, can predict the delay of estimation and planner also can be automatically with this delay owing to a known reason (for example weather).So the automatic dispatching person can automatically predict the generation of other delay of walking this regional train.
In another aspect of the present invention, the function of being carried out by the dispatcher usually can be finished based on the scheduler 140 of computer processor by using.For example, there are many different types of track authorities, it is distributed to the resource of train and other use rail network.Typically, for the authority of determining to issue that is fit to, scheduler need be considered many factors, comprises preferential track type (for example, beidirectional, unidirectional), the work of carrying out (for example, roadupkeep) and that side that authority was suitable for.The issue of the authority that is fit to is to the security sensitive of scheduler and constraint consuming time.In one embodiment, according to the previous same factor of considering of scheduler, the present invention will transfer to scheduler based on computer processor from scheduler to the consideration of these factors, so that by using form generation module 260 that the configurable track authority of automatic unification automatically is provided.Necessary content and permission type are to determine according to the reciever type of authority and restriction, thereby make scheduler, car group personnel and field (or on-the-spot) staff need not be proficient in the different form types of different railways position.Therefore, single dynamically configurable authority form can be replaced previously used numerous authority form.In addition, dispatching system can provide the demonstration of an enhancing for scheduler, so that allow scheduler to use interactive display module 250 promptly to judge within the authority limited field or, and notify scheduler by producing alarms by task list generation module 220 near all trains of this authority restriction.Interactive display module 250 can help scheduler to determine train whether in the zone that the track authority is covered, and eliminates because the possible mistake that authority caused that the cancellation train still needs.This module is equally also convenient exempts the authority that no longer is used, thereby has discharged resource and plan with optimization.
In addition, dispatching system can be accepted the remote electronics authority request from the field, and the type that automatically defines the competence reexamines according to the current state approval of other authority, open-air sign and train position or disapprove or request scheduling person then.
Another scheduling feature that can be adopted by dispatching system is the automatic issue of train bulletin.The train bulletin that is published to train comprises that a plurality of trains that will retrain are along the incident of its Planned Route operation and environment train notified car group personnel's bulletin item.The information that has limited in the bulletin item of row or multiple row train must send the operational plan device to equally.The suitable information that can comprise comprises train speed restriction, track speed limit, should keep away capable track in bulletin, dangerous train operation limits or the like.Typically, the part between the car group personnel of train path change shifts a little in the scheduler control area is distributed to the car group personnel of train by the scheduler of being responsible for before train departure for train bulletin.The train bulletin can comprise the not only control area of a scheduler.Train bulletin is passed on by fax or for car group personnel provide the alternate manner of notice usually, but scheduler must take to separate and independently take action to guarantee that the information in the train bulletin is sent to the operational plan device equally.In one embodiment of the invention, configurable bulletin item offers scheduler by form generation module 260.When producing form, form generation module 260 can be filled in this form in advance with known information, and the train bulletin that comprises a bulletin information is offered car group personnel and operational plan device 120.A bulletin type is configurable so that the handler can create the type of the bulletin item that is easy to use under specific circumstances.The operational plan device can automatically use the plan constraint condition (comprising the constraint condition that is included in the configurable part) that is included in each bulletin item that can be applicable to train, so that upgrade operational plan in case of necessity.The operational plan device receives configurable bulletin from automatic dispatching person 140, and Identification Scheme constraint condition and correspondingly upgrade operational plan.For example, scheduler can be issued announcement to reduce the speed that train is advanced and allowed on a specific part of track.The speed limit of the reduction that 120 identifications of operational plan device are comprised the bulletin item that receives from automatic dispatching person 140, and adjust operational plan on a specific part of track, to underspeed.
In the present invention is aspect another, dispatching system can be provided by the weather service information that is provided by railroad information support center 130, and in train renewal operational plan, automatically consider weather, this comprises the train path in the zone that can influence according to the weather of passing through, in bulletin item, train bulletin and authority, propagate Weather information, and weather warnings is placed in the geographic area that is fit to of scheduler demonstration.
Dispatching system is born common reservation, and to give another field of the responsibility of scheduler be non-productive operation.Typically, the situation of sign needs (for example, the train of fully loaded coal passes through the mountain pass) non-productive operation (for example, using auxiliary locomotive engine that temporary transient additional power is provided for running train) is the responsibility of scheduler purely.In the one embodiment of the invention, dispatching system in assessment operational plan device module 200 automatically sign since the track condition (for example, slope and/or weather and/or curvature topology) may cause the environment of train dynamics deficiency, and dispatch the necessary train of auxiliary power help on route.Dispatching system determines that based on following suitable factor auxiliary essentiality is: such as the needed minimum power of determined topology area and direct of travel in the track data bank, usually carry out the zone of assistant's operation, and in assessment operational plan module 200, form (horsepower according to engine and train, drive weight, traction tonnage etc.) the train performance of prediction.If also do not assign assistant and assessment operational plan module 200 need to determine the assistant, then task list generator module 220 will be created a task when being fit to.So the assistant's tabulation that can be used to assign is shown to scheduler by interactive display module 250.In addition, when the parameter indicating of train and track needs an assistant, so when the plan train by assistant zone and monitor operational plan execution module 210 and monitor task list block 230 when determining not assign the assistant, dispatching system can be warned scheduler in task list producing device module 220.The demonstration that the automatic dispatching person can provide assistant's train to assign in interactive display module 250 is to make things convenient for the efficient strategy management of scheduler to assistant's operation.
In the another embodiment of the present invention, for scheduler provides the demonstration of enhancing, its facility coordinate with the interactive mode of scheduler system.For example, the demonstration of enhancing can allow scheduler to observe the route of the plan of train, and by use " drop-down (drill down) " technology of knowing in interactive display module 250, can make scheduler have the ability of the details of the increase of observing route.In addition, interactive display module can allow scheduler to provide change to operational plan.For example, can provide the stroke plan of the details that has comprised the route of selecting for train to show to scheduler.It is the route that train is selected sign that this scheduler is had the ability by the graphical user interface technology of knowing, and makes a change when situation needs.For example, may plan train A (not shown) and travel on one section track, this section track is consistent with the default track that this train travels usually thereon.Scheduler can be recognized this situation, its need deviate from train A usually expection the path and described be shown as scheduler provide select track part that train A can not utilize again may and provide alternative track for train A.Alternative track is identified and is sent to the operational plan device and removed to use this track to supply with train A.In addition, by the demonstration of the enhancing that provides by interactive display module 250, the ability of the selection of the influential route of scheduler are provided.For example alternative route can be supplied with the train use that drives to a B (for example, through a terminal area) from an A.Alternative route can comprise track that is had by several railroads or the track of being shared by railway.Graphical user interface technology (for example, the drag and drop technology) scheduler of knowing by use can be selected INTRM intermediate point or select to need to use the action of one of selected track, and it is the route that the operation of train is planned that described track influences planner.The track part (that is, the route that can not call can and can be forbidden all interactive functions with the color highlighted demonstration different with the route that can call) that graphic user interface can allow scheduler only to select those scheduler to call.Therefore scheduler can drag and drop makes in the spendable track one section by graphic user interface.
The interactive demonstration also can make things convenient for communicating by letter via communication link 150 between scheduler and train and other resource. for example, can for the communication system parameter (such as frequency of radio, radio/honeycomb launch tower position and transmission scope or the like) with track topology (topography) (Geographic Reference) data bank produce index, and offer scheduler with interactive display module 250. train and operator station are put and are generally known to the dispatching system; And therefore, can automatically determine by interactive display module 250 by dispatching system, the interactive means of communication that the is fit to (radio for example of setting up, radio transmitting tower and frequency or even base, satellite and car group personnel's Mobile Directory Number). for example, in order to communicate with train, scheduler is often selected the train symbol and is shown the aerogram channel of wishing to be opened to train from interactive mode shows. and the automatic dispatching system will determine the position of train, radio communication unit in this position and the track topological database is done cross reference, then this information is sent to Radio Control System to set up suitable communication link.
The interactive mode that strengthens shows also can be for scheduler provide the ability of observing other dispatcher-controlled territory, comprises senior indication and relevant information to the train of the control area that enters scheduler.Scheduler can be visited any part of railway, and the performance of any train, and is not only its that part of plan and train of directly being responsible for.In addition, the interactive mode of enhancing shows also can provide in the position away from the scheduler position.For example, long-distance interactive display module 255 can provide demonstration for the station handler of the operating center that is arranged in the railway station.Compared with the display module of scheduler, interactive display module 255 is less for the visit that the station handler is allowed, and relates to the information that may influence the train operation of operational plan in the station but allow the station handler to provide.For example, because some influence train operation incident or accident in the station, the station handler can provide the notice of the delay of expection.In addition, long-distance interactive display module 255 can also be provided as the means of leaving order and time departure that particular train is specified the track that arrives and leave and specified train for the station handler.According to other existing authority, open-air indication and train position current state, can automatically define the competence type and agree the issue of authority of dispatching system.Via the communication link 258 (such as LAN, WAN or internet) that is fit to, long-distance interactive display module 255 is linked with one or more other modules of automatic dispatching person 140.
In the another embodiment of the present invention, scheduler can be from the analysis feedback of dispatching system request to the change of operational plan suggestion.For example, scheduler can be by the constraint (for example, the track of having selected today partly needs two hours stops service) of interactive display module 255 suggestion hypothesis, so that observe the influence of supposition constraint condition to operational plan.If the constraint of supposing has minimum influence to operational plan, scheduler can ask constraint is considered as truth rather than hypothesis, and correspondingly upgrades operational plan.Therefore, scheduler have the ability to propose " just in case " imagination, and before implementing change, assess the influence of any proposed change.
In addition, by allowing for reserved resource in the future, interactive display module 250 and 255 also can facilitate for plan.Normally, the issue of using and move authority of resource is finished on uncontrived basis, and issue moves authority and do not preplan when needs.By before it requires for the operational plan device provides information, the operational plan device can have more selection to make things convenient for the use of resource.For example, the station handler can be for safeguarding the authority of road future, and the pre-determined plan of this request makes and not too needs special scheduler mutual.
In the present invention on the other hand, the scheduler system allows the real-time configuration of working rule and the compatible constraint condition of Else Rule.In traditional scheduling example, scheduler has to guarantee that the change of operational plan is in accordance with the series of complex operations rule.If working rule has changed or federal railway association (FederalRailroad Association) has implemented new rule, require usually to make software modification to reflect the change of rule for the software business man that dispatching system is responsible for.In one embodiment, the present invention allows railroad or the interactive display module 250 of scheduler utilization directly rule to be changed by configurable parameter and is input in the dispatching system any change of avoiding the third party that function software is made.
