Abstract

In a conventional signaling system, there is room for improvement in reducing the time required from when a preceding train passes through a certain block until a following train can run in said block. In order to solve the above problem, for example, an on-board device receives a message and sends the received message to another device, said message circulating around the trains present within a route constituted by one or more blocks to which the right of occupation of a train is set and including block occupation right information enabling the setting of block occupation right for one train. The on-board device is characterized in that when the block occupation right is set by the message for a train on which the on-board device is mounted, the on-board device mounted on the train for which the right of occupation is set controls a point-switch present in the block to which the right of occupation is set, on the basis of the direction of movement of the train for which the right of occupation is set and by a method different from the circulation of the message.

Description

On-board equipment, trains, and signal security systems

The technical field relates to on-board equipment, trains, and signal security systems.

Patent Document 1 relates to a signal security system: “A track circuit device electrically isolates a rail, connects a power supply to one end, and connects a relay to the other end to detect a short circuit between the rails due to a train. As a solution to this problem, the safety of trains traveling in a predetermined section is ensured based on the telegram. In the signal security system, the telegram circulates trains and equipment along the predetermined section, and the block occupancy right can be set for each block divided into multiple sections. “It has a configuration having right information” (see Patent Document 1 [0010]) and the like.

JP 2006-232106 A

However, in the signal security system of Patent Document 1, there is room for improvement in shortening the time from when a preceding train passes a certain block until the succeeding train can travel through that block.

In order to solve the above problems, for example, the configuration described in the claims is adopted.
The present application includes a plurality of means for solving the above-mentioned problems. To give an example, the train circulates a train that exists in a route composed of one or more blocks in which the right to occupy the train is set. In an on-board device that receives a telegram containing block occupancy right information that can be set for one train and transmits it to other devices, the occupancy right of the block by telegram for the train on which the on-board device is mounted Is set, the on-board device installed in the train with the occupancy right will switch the switch located in the block with the occupancy right based on the traveling direction of the train with the occupancy right set. Thus, it is controlled by a method different from the message circulation.

According to the above means, it is possible to shorten the time from when the preceding train passes a certain block until the succeeding train can travel through that block. Problems, configurations, and effects other than those described above will become apparent from the description of the following examples.

An example of a signal security system An example of a signal security system An example of a signal security system An example of train status Example of message format Example of member list format Example of on-board device processing Example of on-board device processing Example of hardware configuration of on-board device An example of a signal security system An example of a signal security system

As shown in Fig. 1, the signal security system using the circuit of the telegram circulates the telegram between trains and switchboards, and updates the information of the telegram on which the onboard equipment mounted on the train is circulated. It is a mechanism that secures the right to occupy the route that intends to travel and instructs the switch to change direction.

The predetermined section in which the message circulates is divided into a plurality of blocks, and the identification information of the train in which the occupation right is set for each of the plurality of blocks is entered in the message. There is only one train for which an occupancy right is set for each block, and only a train for which the occupancy right for the block is set is allowed to travel on that block. The telegram may be configured to include information indicating the direction of the switch, and the switch controls the direction based on the received message information.

When a train that wants to travel a certain block receives a message, it updates the message so that the ownership of the block is set to its own train, and transmits the updated message to the next train or switch. However, if the occupancy right of the block is already set for another train in the received message, the message cannot be updated to set the occupancy right for the own train, and the block set for the other train You cannot drive the block until your right to occupy is released.

When a train with a block occupancy right receives a message after passing through that block, it updates the message to release the block occupancy right set for its own train, and the next train or The updated message is sent to the device.

If the configuration is such that the telegram is circulated between the train and the switch as shown in FIG. 1, the time required for the telegram to travel becomes longer as the number of trains and the switch is increased. As a result, the control of the switch and the update of the block occupancy right are delayed.For example, the preceding train passes the block where the switch is installed and then switches for the following train. The time to change the direction of the vessel becomes longer, and the interval between trains passing through the block becomes wider.

Therefore, in the following embodiment, control of the switch is performed directly from the train that has obtained the occupation right of the block in which the switch is installed, thereby causing the switch to circulate a message. Eliminate the need for telegrams that include control information only between trains. This makes it possible to reduce the number of devices that circulate a message including control information, and to speed up the update of the control information included in the message.

By the above, even when there are many switchboards, it is possible to control the switchboard by circulating the message between trains, and it is possible to reduce the time required for the message circulation, It is possible to improve the performance of the entire system, such as shortening the train interval.

Furthermore, in order to prevent leaks from occurring in trains subject to telegram circulation, a member list for managing trains subject to telegram circulation is created. The member list is used for updating a list of devices constituting a circuit in which a message circulates. This member list is managed by a method different from the circulation of electronic messages. For example, a configuration may be adopted in which a circuit different from the message circuit is managed by patrolling or managed by communication between trains.

This configuration makes it possible to further improve the operation efficiency of the signal security system.

Hereinafter, the present embodiment will be described in more detail based on the drawings.

Fig. 2 shows the circuit structure of the message security system in Example 1 and the concept of switch control.

In FIG. 2, it is assumed that two trains, that is, the train 101a and the train 101b roll together and pass through a block in which the cage 104 is installed. Furthermore, it is assumed that the train 101a has obtained the right to occupy the block in which the switch 104 is installed before the 101b. The right to occupy the block in which the switch 104 is installed is set by a message that is circulated between the onboard device 102a included in the train 101a and the onboard device 102b included in the train 101b.

Here, the hardware configuration of the on-board device 102 and the switch control device 103 will be described with reference to FIG.

The onboard device 102 and the switch control device 103 are CPU (abbreviation of Central Processing Unit; central processing unit) 902, the onboard device 102, and the switch control device 103 even if the power is turned off. A storage device 903 that can hold data, a transmission / reception device 904 that wirelessly transmits and receives information via an antenna, and a memory 905 that electrically records data are included. The recording device 903 records a program 907 that the CPU 902 expands in the memory 905 and executes.

The recording device 903 is, for example, an optical disk, a flash memory, a hard disk, or the like. The memory 905 is a DIMM (Dual In-line Memory Module), for example.

In the on-board device 102 and the switch control device 103, the transmission / reception device 904 receives a message transmitted from another on-vehicle device or the switch control device. Then, using the received electronic message, the CPU 902 expands the program 907 recorded in the recording device 903 in the memory 905, and performs the update process of the electronic message described later. Then, the processing result of the CPU 902 is transmitted to the outside by the transmission / reception device 904.

Next, the messages that are circulated will be explained. FIG. 5 shows an example of information included in a telegram for setting an occupation right for a train in this embodiment. In the “block occupation right column” of FIG. 5, the identification information of the train having the occupation right of each block of blocks 1 to 6 is entered. The occupation right of each block is set only for one train. When a train enters each block, the occupancy right for that block must be set.

In the “Train member list” in FIG. 5, the identification information of the train on which the message is circulated is entered. The train that has received the message transmits the message to the next train based on this “train member list”. In the present embodiment, the “train member list” is included in the telegram, but it is not necessarily included in the telegram. For example, you may comprise so that each train may grasp | ascertain the train which circulates a message | telegram by another method, such as managing the list | wrist of the train which circulates a message | telegram, and contacting each train.

For example, when train A, which is going to travel in blocks 1 to 3, receives a telegram, it updates the telegram to set the occupancy right of that block to its own train, and updates to the train that circulates the next telegram based on the train member list Send a message. However, if the occupancy right of the block is already set for another train in the received message, the message cannot be updated to set the occupancy right for the own train, and the block set for the other train You cannot drive the block until your right to occupy is released.

When train A with the occupancy rights of blocks 1 to 3 receives the message after passing through blocks 1 to 3, it updates the message to release the occupancy rights of blocks 1 to 3 set for train A. Then, the updated message is transmitted to other trains.

The onboard device 102a in which the occupation right of the block in which the switch 104 is installed is set is compared with the switch control device 103 that controls the switch 104, and the train 101a is connected to the switch 104. An instruction (control command) is transmitted to change the direction to pass. The on-board device 102a controls the train so that the train 101a stops before the switch 104 until the switch of the switch 104 is completed.

As for whether or not the on-board device has a switch in the block for which the occupation right is set, the information on the switch in each block is stored in the recording device 903 in advance. This can be confirmed by referring to the information.

The switch control device 103 that has received the switch instruction of the switch from the on-board device 102a switches the switch 104 in the indicated direction, and after the conversion is completed, Information indicating that the conversion is completed (hereinafter referred to as “switching device conversion completion information”) is transmitted to the on-board device 102a.

The on-board device 102a that has received the switchover completion information permits the train 101a to pass the block where the switch 104 is installed. After the train 101a passes the block where the switch 104 is installed, when the on-board device 102a receives the message, it updates the message so as to release the occupation right of the block set in the train 101a, It transmits to the upper apparatus 102b.

When the on-board device 102b receives the message updated by the on-board device 102a, the on-board device 102b updates the message so that the occupancy right of the block on which the switch 104 is installed is set to the train 101b. Then, the onboard device 102b transmits an instruction to change the direction of the rolling device 104 according to the traveling direction of the train 101b to the rolling device control device 103, and after the conversion is completed, the train 101b is turned. The train 101b is controlled so as to pass through the block where 104 is installed.

In this way, a train with the right to occupy the block in which the switch is installed controls the switch and obtains information on the state of the switch and travels, so that multiple trains It is possible to safely control the switch used by the vehicle and to run the train safely. In addition, since it is not necessary for the switch control device to circulate the message, the time required for the message circulation can be shortened.

In addition, when both the process of circulating the message and the process of controlling the switch in the on-board device are performed by wireless communication, if the same frequency band is used, the two wireless communication will collide (collision), and the message Transmission efficiency may be reduced. Therefore, it is preferable that the frequency band of the wireless communication used for circulating the electronic message is different from the frequency band of the wireless communication used for controlling the switch.

Moreover, it is good also as a structure provided with two radio | wireless communication apparatuses, the radio | wireless communication apparatus which performs the process which circulates a message | telegram, and the radio | wireless communication apparatus which performs the process which controls a switch.

The management of the train member list for managing the trains subject to the circulation of the message will be described with reference to FIGS. By managing the train member list described in the present embodiment in addition to the control of the switch device described in the first embodiment, it is possible to further increase the efficiency of train operation.

場合 When a new train enters the area controlled by the message, it is necessary to add the train to members who circulate the message. As a method for this, a request for registering the own train to a train or a member who circulates a message to the ground device in the range where the new train is controlled to be closed (hereinafter simply referred to as “registration request”). It is conceivable that a train or ground device in a range that is controlled to be blocked by a message is added to a member who detects the new train and circulates the message.

However, when the telegram is circulated between trains as in Example 1, since the train is moving, the accuracy of receiving a registration request from a new train and the accuracy of detecting a new train are reduced. It is conceivable that the invasion of the new train into the area where the block control is performed by the telegram is delayed. On the other hand, since ground devices such as a switch do not move like trains, the accuracy of receiving registration requests from new trains and the accuracy of detecting the entrance of new trains are higher than trains. .

Therefore, trains that circulate telegrams are managed using a method different from that of telegrams, thereby improving the accuracy of receiving registration requests from new trains and detecting the intrusion of new trains. It becomes possible to raise.

In the present embodiment, as an example, a member list (second message) used for managing a member list of a train that circulates the message separately from the message (first message) includes a ground device such as a switch. An example will be described in which the operation efficiency of the train is further increased by circulating the route.

As an example, two trains, train A and train B, are present in Fig. 4 and both trains are going to pass through the block where the anchor 1 is installed, and the blocks indicating the train location are blocks 1 to 4. Indicates a certain state. Here, assuming that the right to occupy blocks 1 to 3 is set for train A, the message that circulates between trains at this time is as shown in FIG.

The train member list in FIG. 5 is a list of trains that are subject to circulation of telegrams, and is information included in telegrams that travel between trains. As described in the first embodiment, the information of the train member list may not necessarily be included in the telegram, and may be configured so that each train grasps the train that circulates the telegram by other methods.

The member list in FIG. 6 includes a ground device such as a switch that exists in the range controlled by the telegram in addition to the train circulating the telegram.

Next, control using the message shown in FIG. 5 and the member list shown in FIG. 6 will be described with reference to FIG. In this embodiment, in order to manage the train member list, two routes are created: a route for circulating the telegram of FIG. 5 and a route for circulating the member list of FIG.

5 is the same as the circuit shown in FIG. 2 and is called a message circuit 301. The telegram circuit 301 is a circuit indicated by a solid line, and is composed only of an on-board device mounted on a train.

The other circuit is a circuit for circulating the member list, which is indicated by a broken line in FIG. The member list circuit 302 is composed of a train and a switch.

The train that circulates the telegram sets the block occupation right by telegram and controls the switch, and the member list of the train that circulates the telegram is managed using the member list that is circulated by the member list circuit 302 To do. Since the member list is not used for block occupancy rights or control of the switch, it is not required to reduce the time required for one round compared to a message. As a result, even if the number of ground devices such as switchboards increases, the message circulation circuit 301 that circulates the message is not affected.

Next, a method for managing a member list (train member list) for circulating a message (first message) using the member list (second message) will be described in more detail with reference to FIGS. . First, the processing when the member list is received will be described with reference to FIG.

Step 701: The member list shown in FIG.

Step 702: Save the received member list.

This process makes it possible for each device in which the member list is circulated to maintain the latest member list.

Next, the processing when the on-board device of the train receives a message using FIG. 8 will be described.

Step 801: The electronic message shown in FIG.

Step 802: The train member list is extracted from the message.

Step 803: Refer to the member list saved in Step 702.

Step 804: The train member list extracted in step 802 is compared with the member list referred to in step 803. If there are trains that are not in the train member list in the member list, the number of trains in the range controlled by the telegram has increased. Judgment is made and step 805 is executed. If not, go to Step 806.

Step 805: The identification information of the trains determined to be increased in step 804 is added to the train member list of the message.

Step 806: Similar to step 804, the train member list extracted in step 802 is compared with the member list referred to in step 803, and if there is a train that is not in the member list in the train member list, the blockage controlled by the message It is determined that the number of trains has decreased, and Step 807 is executed. If not, go to Step 808.

Step 807: The identification information of the train determined to be the train reduced in Step 806 is deleted from the train member list of the message.

Step 808: The message is circulated based on the train member list updated in Step 805 and Step 807.

Through the above processing, it is possible to manage the train member list of the telegrams circulated using the telegram circuit 301 using the member lists circulated using the member list circuit 302.

It should be noted that whether communication in the circuit of the member list circuit 302 and the message circuit 301 is performed by one transmission / reception device 904 or whether a different transmission / reception device 904 is installed for each circuit depends on the communication method for each circuit. Good.

The processing in steps 701 to 702 and steps 801 to 808 is performed by the CPU 902 using the memory 905 to execute the program 907 recorded in the recording device 903. Further, the member list saved in step 702 is stored in the recording device 903 or the memory 905.

Also, in this embodiment, two traveling circuits, a telegram circuit 301 and a member list circuit 302, are used in order to shorten the time required for the circuit circuit, but high-density train operation such as a commuting time zone is necessary. The configuration of the circuit is dynamically changed according to the required system response time, such as applying the present embodiment at the time that is assumed to be performed and performing the control described in the prior art at other times. Is also possible.

As described above, by appropriately managing the train member list that is subject to the circulation of the message, while improving the accuracy of receiving registration requests from new trains to the range controlled by the message and the detection accuracy of new trains , It will be possible to reduce the time required for message circulation and increase the operating efficiency of the entire system.

In the second embodiment, in order to manage the train member list that is the target of traveling the telegram, an example has been described in which the two travel circuits of the telegram circuit 301 and the member list circuit 302 are configured. The structure which manages a train member list | wrist without using the list patrol circuit 302 is shown. The control method of the switch is the same as in the first embodiment.

FIG. 10 shows a conceptual diagram of this embodiment. FIG. 10 shows a situation in which the train 101b is about to enter an area where the train 101a is in a closed state controlled by a telegram. At this time, the on-board device 102b transmits a registration request 1001 to all the trains in the area. Upon receiving the registration request 1001, the onboard device 102a adds the train 101b to the train member list, and transmits a telegram including the train member list to the onboard device 102b as a registration completion notification 1002. The on-board device 102b that has received the registration completion notification 1002 circulates a message to the message circuit 301 according to the received train member list. The registration completion notification 1002 may be transmitted separately from the onboard device 102a to the onboard device 102b as a notification different from the electronic message.

When there are a plurality of trains in the area, the train 101b can be added to the train member list by transmitting a registration completion notification 1002 from at least one of the trains in the line.

If the on-board device 102b cannot receive the registration completion notification 1002, the on-board device 102b stops the train 101b before entering the area. This prevents the train from entering the area without being added to the train member list. The on-board device 102b repeats the simultaneous transmission of the registration request 1001 until the registration completion notification 1002 is received. If the registration completion notification 1002 cannot be received for a certain period of time, the operator may enter the area after confirming safety, such as entering the area after confirming the operation management commander.

As described above, the train member list can be managed and the train can be efficiently run without circulating the member list (second telegram) different from the telegram by the train and the ground device.

In the third embodiment, an example has been described in which a train entering an area controlled by a telegram transmits a registration request to the train member list of the telegram to a train or ground device in the area. Shows a configuration in which the ground device transmits a registration request. The control method of the switch is the same as in the first embodiment.

FIG. 11 shows a conceptual diagram of this embodiment. FIG. 11 shows a situation in which the train 101c is about to enter an area where the trains 101a and 101b are in the closed state by electronic messages. At this time, the switch control device 103 that first detects the train 101c simultaneously transmits a registration request 1101 to the train in the area. The onboard device 102b that has received the registration request 1101 adds the train 101c to the train member list, and transmits a telegram including the train member list to the onboard device 102c as a registration completion notification 1102. The on-board device 102c that has received the registration completion notification 1102 circulates a telegram according to the received train member list. The registration completion notification 1102 may be separately transmitted from the onboard device 102b to the onboard device 102c as a notification different from the electronic message.

When there are a plurality of trains in the area, the train 101c can be added to the train member list by transmitting a registration completion notification 1102 from at least one of the trains in the line.

If the on-board device 102c cannot receive the registration completion notification 1102, the on-board device 102c stops the train 101c before entering the area. This prevents the train from entering the area without being added to the train member list. The switch control device 103 repeats the simultaneous transmission of the registration request 1101 until the reception of the registration completion notification 1102 by the on-board device 102c can be confirmed. If the registration completion notification 1102 cannot be received by the on-board device 102c for a certain period of time, after confirming the safety, such as entering the area after confirming the operation management commander, let the train 101c enter the area. May be.

It should be noted that the signal security system described in the first to fourth embodiments can be applied not only to railroad trains but also to cars traveling on a predetermined route. For example, in a highway, a message is circulated between vehicles to ensure security. Or in amusement parks, parks, etc., there is a case where a message is circulated between vehicles traveling on a route or course where a course is determined in advance to ensure security.
