Abstract

In a signaling safety system of a conventional technique, there has been room for improvement in reducing the time from when an on-board device of a preceding train has released the right of occupying a block until the following train can run in the block. An on-board device receives a telegraph and sends the telegraph to another device, said telegraph circulating through trains and trackside devices present in a route constituted by one or more blocks to which the occupation right of the train is set, and including block occupation right information enabling the setting of the right of occupying a block to one train. The telegraph includes block occupation right reservation information indicating a train to which the right of occupying a block is to be set next to a train to which the right of occupying the block has been set by the block occupation right information. The on-board device is configured so as to, in response to the release of the right of occupying a block set by the block occupation right information to the train on which the on-board device is mounted, rewrite the block occupation right information for the block so that the right of occupying the block is set to the train indicated by the block occupation right reservation information corresponding to the block.

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.

JP 2006-232106 A

However, in the signal security system of Patent Document 1, there is room for improvement in reducing the time from when the on-board device of the preceding train releases the right to occupy the block until the succeeding train can travel on that block. there were.

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 and the equipment along the route that are composed of one or more blocks in which the occupation right of the train is set are patrolled. An on-board device that receives a message containing block occupancy information that can be set for one train and transmits it to another device. Includes block occupancy right reservation information indicating the train for which the occupancy right of the block is set next to the set train, and the onboard device is set to the train on which the onboard device is mounted according to the block occupancy right information As a block occupancy right is released, the block occupancy information of the block can be rewritten so that the occupancy right of the block is set in the train indicated by the block occupancy right reservation information corresponding to the block. The features.

According to the above means, it shortens the time from when the on-board device of the preceding train releases the right to occupy the block until the switch device belonging to that block starts to change in the direction of the route on which the subsequent train travels. It becomes possible to do. Problems, configurations, and effects other than those described above will become apparent from the description of the following examples.

Diagram showing an example of a signal security system The figure which shows the area and block in Example 1. The figure which shows the course of the train in Example 1 The figure which shows the content of the security message in Example 1 Security telegram contents in steps 1 to 4 in the first embodiment Security telegram contents in steps 5 to 9 in the first embodiment The figure which shows the position of the train in step 7 of Example 1

In the signal security system using the circulation of the electronic message, the on-board device mounted on the train updates the information of the electronic message that is circulated to secure the right to occupy the block on the route intended to travel, and the block This is a mechanism for instructing the switch direction to the switch. Therefore, when trying to travel on a route in which a plurality of trains compete in order, after the first train exits the competing block, the on-board device mounted on that train will occupy the right of ownership of the block that competes on the telegram Next, the onboard device installed in the second train that received the message secures the right to occupy the block on the message, and instructs the switch device belonging to the block to change direction. Furthermore, only when the message is transmitted to the turning device, the turning device starts to change direction of the route on which the second train travels.

At this time, when the circulation order of the message is the order of the onboard device of the first train, the switch device, and the onboard device of the second train, the onboard device of the first train has the right of occupation. Until the on-board device of the second train instructs the switch to the switch, the telegram goes through the switch device and requires two transmissions. In order for the conversion instruction to be transmitted to the switch device, it will go through the on-board device of the first train, requiring two transmissions / receptions, and a total of four message transmissions / receptions.

In other words, depending on the message circulation order, the switch control device needs to wait for two messages until a new conversion instruction is received. This is because the on-board device of the preceding train releases the right to occupy the block. After that, it means that it takes time for the telegram to be transmitted and received between the devices existing in the control area more than once until the switch belonging to the block starts to change in the direction of the course of the following train. . This time can be a factor that hinders high-speed train operation.

In this embodiment, the time from when the on-board device of the preceding train releases the right to occupy the block to when the switch belonging to the block starts to change in the direction of the route on which the subsequent train travels is shortened. Disclosed is a signal security system capable of operating a train with high density regardless of the circulation order of messages.

According to the present embodiment, when trying to travel in order on a route in which a plurality of trains compete, the onboard device mounted on the train competes on the telegram after the first train exits the competing block. Simultaneously with the release of the occupancy right of the block to be activated, the block occupancy right reservation information by the on-board device mounted on the second train and the switch instruction reservation information to the switch belonging to the travel route are made valid After the release of the right to occupy the block with which the first train competes, the switch control device, regardless of the message circulation sequence, You can start to change the direction of the track that your train is traveling.

Hereinafter, it will be described in more detail with reference to the drawings.

As shown in FIG. 1, the signal security system according to the present embodiment includes an onboard device 101 mounted on the train 1, an onboard device 102 mounted on the train 2, and a switch that controls the switch 3. It is comprised from the container control apparatus 103 and the security message | telegram 201 which is the message | telegram circulated between the on-board apparatus and a switch control apparatus.

The entire route on which the train runs is divided into a plurality of predetermined areas, and further, one area is divided into units that can be occupied by only one train, and this divided section is called a block. In this embodiment, as shown in FIG. 2, the entire route is divided into three areas, area 10, area 20, and area 30, and area 10 is divided into four blocks, block 11, block 12, block 13, and block 14. To divide.

The thick arrows in FIG. 3 indicate the course of the train in area 10. The route is a route on which the train travels, the route 15 is a route that reaches the block 13 from the block 11 through the block 12, and the route 16 reaches the block 11 from the block 14 through the block 12. The way to do. In addition, regarding the direction of the switch 3, the direction in which the path 15 is opened is the orientation, and the direction in which the path 16 is opened is the inversion. Note that the localization / inversion is a term indicating the direction of the tipping device, the localization indicates the steady opening direction, and the inversion indicates the reverse direction of the localization.

Then, all block occupation right information and reservation information of area 10, direction indication information to all switchboards, reservation information thereof, and status information of all switchboards are managed by one security message. The safety telegram is circulated between the on-board devices of all trains traveling in the area and all the switch devices in the area.

The security message may manage the above information in any form, but in this embodiment, as shown in FIG. 4, the area identification column 211, the member list column 212, the block occupation right column 213, the block occupation right The reservation column 214, the switch direction indication column 215, the switch direction indication reservation column 216, and the switch state column 217 will be described in an organized manner.

In the area identification field 211, identification information of the area managed by the security message is entered. In the member list column 212, a list of devices that circulate the security message and their circulation order are entered.

In the block occupancy right column 213, the identification information of the train having the block occupancy right is entered. This right to occupy a block must be secured in order for the train to enter the block, and only one train can be secured per block. When the security message is received, the block occupation right can be secured by entering the identification information of the own train only when there is no entry by another train.

In the block occupation right reservation column 214, identification information of the train that reserved the block occupation right is entered. When receiving a security message, if there is an entry by another train and the block occupancy right cannot be secured, the block occupancy right can be reserved by entering the train identification information in the reservation field of the block occupancy right it can. This reservation is executed by transferring the train identification information written in the reservation column by the released on-board device to the block occupation right column corresponding to the reservation column when the block occupancy right is released. Is done.

In the switch direction indication column 215, instruction information for instructing the direction of the switch is written by the on-board device of the train having the block occupation right to which the switch belongs. The switch control device converts and locks the switch according to this instruction.

In the switch direction indication reservation column 216, instruction reservation information for reserving the direction indication of the switch is entered by the on-board device of the train that reserved the block occupation right to which the switch belongs. . In this reservation, when the block occupation right to which the switch belongs is released, the direction indication entered in the reservation column by the released on-board device is transferred to the switch direction indication column corresponding to the reservation column. As a result, the system is executed.

In the tipping device state column 217, information on the state of the tipping device is entered by the tipping device controller. If it is locked in position, it is written as stereotactic lock, if it is locked in reverse, inverted lock, during conversion, etc., otherwise it is written as non-locked. When the on-board device receives the security message, the on-board device can confirm the lock direction of the switch by checking the switch state column.

Next, the mechanism in which the signal security system of the present embodiment realizes train interval control, exclusive control, and route configuration control in the control area is exemplified by the case where the train 1 travels on the route 15 shown in FIG. I will give you a description. In addition, the content of the security message in each step is shown in FIG.

Step 1: When the train 1 is going to travel on the route 15, the on-board device 101 mounted on the train 1 receives the security message 201, and blocks 11, 12, The block occupancy right of 13 is secured, a direction change instruction to the switch 3 on the route is entered in the switch direction indication column, and the security message 201 is transmitted to the next device.

Step 2: When the switch control device 103 receives the security message 201, the switch control device 103 switches based on the switch direction instruction information entered in the switch direction instruction field of the security message 201. Start the conversion of the vessel 3 to the stereo position.

Step 3: Thereafter, the switch control device 103 checks the state of the switch 3 every time it receives the security message 201, and if it is locked in place, the switch of the security message 201 In the vessel status column, enter that the vessel 3 is locked in place.

Step 4: And when this security message 201 is circulated to the onboard device 101, the onboard device 101 confirms that the switch 3 is locked in place, and the route 15 with respect to the train 1 Give permission to proceed.

It should be noted that when the security message is communicated, it is performed by a method that can confirm that the message has been reliably transmitted to the other party so that the communication message is not intercepted or obstructed and the data is not altered, copied, or lost. For example, encryption and decryption of communication, addition of serial number, addition of time information, check of communication time, advance confirmation and subsequent confirmation of transmission / reception source, return of data, data validity check by error detection code for data, etc. Do.

Next, when the signal security system according to the present embodiment tries to travel in order on a route in which a plurality of trains compete, the release order of the blocks competing with the first train is released, and then the circulation order of the security telegrams Regardless, the switch control device can start the switch of the switch in the direction of the route on which the second train travels based on the switch instruction on the security message received the first time. The mechanism will be described by taking as an example a case where the second train 2 travels on the route 16 shown in FIG. 3 after the first train 1 travels on the route 15 shown in FIG. 3. The contents of the security message at each step are shown in FIG.

First, the mechanism until the train 1 is permitted to travel on the route 15 is the same as the above-described Step 1 to Step 4.

Next, the system behavior until the train 2 that intends to travel on the route 16 reserves the block occupancy right and the switch direction instruction and becomes effective will be described.

Step 5: The on-board device 102 mounted on the train 2 confirms the occupation right of the

blocks

14, 12 and 11 when receiving the security message 201. As a result, although the occupation right of the block 14 can be secured, the occupation rights of the

blocks

12 and 11 secured by the train 1 cannot be secured. Therefore, the on-board device 102 reserves the block occupation right by entering identification information of the own train in the block 12 and block 11 occupation right reservation columns. In addition, an inversion change instruction is reserved in the direction instruction reservation column of the switch 3 belonging to the block 12.

Step 6: After the tail of the train 1 traveling on the route 15 has passed through the block 11, when the onboard device 101 receives the security message 201, it releases the occupation right of the block 11, and confirms the reservation column accordingly. Then, the identification information of the train 2 reserved in the occupation right column is entered, and the identification information of the train 2 in the reservation column of the block 11 is deleted and transmitted to the next device. It is not always necessary to delete the identification information of the train 2 in the reservation column of the block 11, and other trains and switch control devices are filled with the same train identification information in the occupation right column and the reservation column of the block 11. In such a case, the identification information entered in the reservation field may be deleted.

Step 7: Similarly, after the end of the train 1 exits the block 12 as shown in FIG. 7, when the onboard device 101 receives the security message 201, it releases the occupation right of the block 12, and accordingly By confirming the reservation column, the identification information of the reserved train 2 can be entered in the block occupation right column, and the identification information of the train 2 in the reservation column of the block 12 can be deleted. Further, the direction indication reservation column of the switch 3 belonging to the block 12 is confirmed, the reserved direction indication is entered in the direction indication column of the switch 3, and the direction of the switch 3 is set. The inversion direction instruction in the instruction reservation column is deleted and transmitted to the switch control device 103 which is the next device. In addition, it is not always necessary to delete the direction instruction in the opposite direction of the direction indicator reservation column of the switch 3, and other trains and switch control devices are used to change the direction indicator column and direction indication reservation of the switch 3. When the same direction instruction is entered in the field, the identification information entered in the direction instruction reservation field may be deleted.

Step 8: When the switch control device 103 receives the security message 201, the switch control device 103 starts to switch the switch 3 in the inversion direction indicated, and the switch status information field of the security message 201 is displayed. Update to unlocked.

Step 9: After the switch of the switch 3 to the upside down and the locking is completed, the switch control device 103 updates the switch state information column of the security message to the upside down lock. The on-board device 102 that has received the approval gives the train 2 permission to travel on the route 16.

Thus, with respect to the train 1 that travels along the route 15 and the train 2 that intends to travel along the route 16 thereafter, train interval control, exclusive control, and route configuration control are realized. In particular, in step 7, the onboard device 101 mounted on the train 1, not the onboard device 102 mounted on the train 2, indicates the direction to the switch 3 by the train 2 when the occupation right of the block 12 is released. Even if the security message 201 is circulated to the switch control device 103 before being circulated to the onboard device 102, the switch control device is activated. 103 can start the switch of the device 3 in the direction indicated by the on-board device 102 based on the security message received for the first time.

In this embodiment, the case where there are two on-board devices and one switch control device in the area has been described, but naturally there are three on-board devices and switch control devices. It may exist above. Further, although the area 10 is divided into four blocks, it may be divided into five or more finely. All block occupancy rights in area 1 and direction instructions and status information for all switch devices are managed by one security message. May be managed.

When the signal security system of the present embodiment is applied to a route that operates a train at a high density, there are a large number of on-board devices and switch control devices in one area, and the security message is a large number of devices. As the number of devices increases, the time for the security message to make a round between the devices becomes longer. Even in such a case, the signal security system according to the present embodiment cancels the block occupation right by the onboard device of the preceding train and releases the block occupation right by the onboard device of the following train and the transfer belonging to the travel route. By executing the switch instruction reservation to the telescope, the switch control device switches to the direction of the route of the succeeding train when it receives the first security telegram regardless of the circulation order of the security telegram. You can start the conversion of the vise. That is, when operating a large number of trains, there is an effect of shortening the operation interval, and the trains can be operated with high density.

In the present embodiment, the configuration in which one reservation column is provided in the message has been described. However, a plurality of reservation columns having different priorities are provided, and the reservation column having the highest priority is executed in accordance with the release of the block occupation right of the preceding train. And it may be configured to raise the priority of other reservation columns.

In addition, this invention is not limited to the above-mentioned Example, Various modifications are included. The above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described.
