To solve this problem, there is provided a signal security system in which a telegram including, e.g., information of the right to occupy the block in which a travel route is divided into one or more parts, is circulated in order among the onboard devices of trains traveling through the travel route, whereby the information of the right to occupy the block is shared, and safety of train travel is ensured by a design that allows only one onboard device to occupy certain blocks, wherein a telegram circulation management means for deciding the circulation sequence for the telegram is provided, and a device for circulating the telegram is instructed where to circulate the telegram.

Description

On-board device and signal security system

The technical field relates to on-board devices and signal security systems.

JP 2006-232106 A (Patent Document 1) describes a signal security system as follows: “A track circuit device has a rail electrically insulated, a power supply connected to one end, and a relay connected to the other end. "It is a device that detects a short circuit between rails due to a train, and the maintenance and maintenance cost of the device is high" (see Patent Document 1 [0006]). In a signal security system where the safety of trains is secured based on telegrams, telegrams travel around trains and equipment along a predetermined section, and trains one block at a time in which the section is divided into multiple blocks. For example, a configuration having block occupancy right information that can be set ”(see Patent Document 1 [0010]).

Japanese Patent Laid-Open No. 2006-232106

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 problem. To give an example, a message including a plurality of blocks obtained by dividing a travel route into one or more, and block-specific occupancy information is set for each block. On-vehicle devices that transmit and receive messages that are circulated in the road, and message circulation management that determines the message circulation order and directs the message circulation destination to the devices that circulate messages in the road A signal security system comprising: means.

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.

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 The figure which shows the structural example of the signal security system in Example 2.

The signal security system using the circulation of the message secures the right to occupy the block on the route where the traveling is planned by updating the information of the message that the on-board device mounted on the train is circulated. It is a mechanism to instruct the direction of conversion to the switch that belongs to, and to operate the train safely. 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 switch controller, the switch of the switch starts in the direction of the route on which the second train travels.

Therefore, if the time for transmitting and receiving a message for each time becomes longer, the time until the change instruction is transferred to the device controller becomes longer, and this may be a factor that hinders the operation of the train at high density.

In addition, when the circulation order of the messages is defined in the order of the onboard device of the first train, the switch control device, and the onboard device of the second train, the onboard device of the first train is From the release of the occupation right until the on-board device of the second train gives an instruction to switch to the switch, the telegram passes through the switch controller and requires two transmissions. In addition, in order for this conversion instruction to be transmitted to the switch control device, it will go through the on-board device of the first train, requiring two transmissions / receptions, requiring a total of four transmissions / receptions of messages. Become.

This is because the switch control device needs to wait for two messages before receiving a new switching instruction depending on the circulation order of the messages, and the on-board device of the first train has the right to occupy the block. It takes time for the telegrams to be transmitted and received between the devices existing in the control area one or more times after the release until the switch belonging to the block starts to change in the direction of the route on which the second train travels. Means.

In other words, in a signal security system using telegram circulation, the time of transmission / reception of a single telegram and the sequence of circulation of telegrams are factors that hinder the operation of the train at high density.

According to the present embodiment, by providing the circulation management means for determining the circulation order of the message, the information amount of the message is reduced compared to the case where the circulation order is defined on the message, and the time for transmitting / receiving the message is shortened. In addition, when the first train exits the competing block, it instructs the on-board device of the first train to circulate the message to the on-board device of the first train. The device is instructed to circulate the message to the on-board device of the second train, and the on-device of the second train is sent to the switch control device belonging to the competing block. , It is possible to shorten the time from when the first train passes the competing block until the second train can travel through that block.

That is, in this embodiment, instead of prescribing the circulation order of the messages on the message, a circulation management means for determining the circulation order of the messages is provided, and this means always instructs each device to the message circulation destination. Thus, a signal security system capable of operating a train with high density by suppressing the amount of information of a message and preferentially circulating to a device that requires a message is disclosed.

Hereinafter, embodiments of the present invention 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. The device control device 103, the message circulation management means 104, the message circulation management device 4 in which the device is mounted, and the security message 201 that is a message to be circulated between the on-board device and the switch control device. Is done. All devices have communication means for transmitting information with other devices.

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. The switch time of the switch is A seconds.

All the block occupancy rights information in area 10, direction indication information to all the switchboards, and state information of all the switchboards are managed by one security message 201.

The security message 201 may manage the above information in any form, but in this embodiment, as shown in FIG. 4, an area identification column 211, a block occupation right column 213, a switch direction indication column 215, which will be described in an organized manner by using the rolling device state column 217.

In the area identification field 211, identification information of the area managed by the security message is 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 switch direction indication column 215, instruction information for instructing the direction of the switch is entered by the on-board device of the train having the occupation right of the block to which the switch belongs. The switch control device converts and locks the switch according to this instruction.

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.

And this security message 201 is circulated between the on-board device of the train traveling in the area and the switch control device in the area according to the order instructed by the message circulation management means 104.

The message circulation management means 104 may instruct the circulation order of the messages in any form to the on-board device or the switch control device. This will be described in the form in which the circulation order is instructed by the notification from the device controller.

In addition, when the last part of the train passes through the block, the on-board device installed in the train notifies the message circulation management means to that effect by radio or the like. Instruct the device holding the message to circulate the security message to the on-board device. Subsequently, if another train is waiting for the release of the right to occupy the block, the in-vehicle device is instructed to circulate to the on-board device of the waiting train after updating the security message.

In addition, when the on-board device enters an instruction to switch to the switch on the security message, if the on-board device notifies the message circulation management means by radio or the like, the on-board device manages the on-board device. Is instructed to circulate a security message to the switch control device that controls the specified switch. When there are a plurality of switch control devices, first the in-vehicle device is instructed to circulate a security message to the first switch control device, and then the first switch is connected. Instruct all the switch control devices to circulate the message, such as instructing the switch control device to circulate the security message to the second switch control device.

In addition, when the switch control device notifies the message circulation management means by radio or the like when the state of the switch changes, the message circulation management means holds the security message at that time. Instruct the device in charge to circulate the security message to the switch control device. Next, after updating the security message to the switch control device, if there is a train with the right to occupy the block to which the switch belongs, it will be circulated to the on-board device of the train. Instruct.

In all of the above cases, if the message circulation management means has already instructed the device holding the security message at that time to circulate the security message to another device, the message circulation management means Instruct the circulation destination for the next device to be circulated. If the device has already instructed the circulation destination, the next device, such as the next device, is scheduled to circulate the security message, but the device has not yet instructed the circulation destination. Be sure to indicate the destination.

Next, the signal security system of the present embodiment circulates the security message as described above, and in the control area, implements a mechanism for realizing train interval control, exclusive control, and route configuration control.
