Description of embodiments

In a signaling security system that uses circulation of a telegram, an on-board apparatus mounted on a train is configured to ensure a right to occupy a block on a route on which the train will travel by updating information of a telegram to circulate, and to give the lock position instructions to a switch belonging to the block. Therefore, in a case where a plurality of trains will successively travel on a non-simultaneous route in sequence, after a first train has left the non-simultaneous block, an on-board device mounted on the train gives the right to Occupying the non-concurrent block in the telegram, and subsequently, an on-board device mounted on a second train that has received the telegram ensures the right to populate the block in the telegram and provides lock position instructions to a switch that belongs to the block. Further, the telegram is transmitted to a switch device, and the switch begins to be switched to a blocking position on the route on which the second train travels.

In this case, if the order of the circulation of the telegram is the order of the on-board device of the first train, the switch device and the on-board device of the second train, the telegram passes until the on-board device of the second train gives the switch change instruction after the on-board device of the first train releases the right to occupy the block, the switch device, and therefore two transmissions and receptions are required. In addition, in order to transmit the changeover instruction to the route device, the changeover instruction traverses the on-board device of the first train and therefore two transmissions and receptions are required. Accordingly, a total of four transmission and reception operations of the telegram are required, that is, more than one circulation of the telegram is required.

That is, the turnout control device must wait two rounds of the telegram until a new changeover instruction is received, depending on the order of the telegram circulation. This means that a time for the telegram to start up devices that exist in a control area once or more frequently in turn until a switch belonging to the block starts to a blocking position of a route on which a subsequent train It will then move after an on-board device of a previous train releases the right to occupy the block. Time can cause disruption to the operation of high density trains.

In the present embodiment, there is disclosed a signaling security system in which, after an on-board apparatus of a preceding train releases the right to occupy the block, a switch belonging to the block, one time to one time, the direction of a following one route Turning trains, shortens and allows trains to drive at high density without the order of circulation of a telegram.

According to the present embodiment, in a case where a plurality of trains on a non-simultaneous route are consecutively driven after a first train has left the non-simultaneous route, an on-board device mounted on the train gives the right to Occupy the non-concurrent block in the telegram and activate both block occupation reservation information and change instruction reservation information to a switch belonging to a second train route at the same time. Therefore, regardless of the circulation order of the telegram, after the first train has left the non-simultaneous block, the switch control means can switch the switch to the blocking position of a route on which the second train is traveling, based on the change instruction of the telegram the first train is received, begin.

Hereinafter, a detailed description will be given with reference to the drawings.

Embodiment 1

Referring to 1 For example, the signaling security system of the present embodiment includes an on-board device 101 on a train 1 is mounted, an on-board device 102 on a train 2 is mounted, one Soft control device 103 that a switch 3 controls, and a signaling message 201 which is a telegram circulating between the on-board devices and the switch controller.

The entire route on which a train travels is subdivided into a plurality of predetermined areas, and further, an area is divided into units, which is allowed to occupy only one train. The subdivided intervals are called blocks. In the present embodiment, as in 2 shown, the entire route is in three areas from one area 10 , an area 20 and an area 30 divided, and the area 10 is in four blocks from a block 11 a block 12 a block 13 and a block 14 divided.

In 3 a bold arrow indicates a distance of a train in the area 10 , The track is a path on which a train travels and the track 15 is a way from the block 11 to the block 13 over the block 12 , and the track 16 is a way from the block 14 to the block 11 over the block 12 , In addition, with respect to the blocking position of the switch 3 a blocking position to clear the route 15 as a normal position, and a blocking position to clear the route 16 is referred to as a transferred position. In addition, the normal position and the folded position are terms that represent blocking positions of points. The normal position denotes the normal position of the switch. The folded position is the opposite of the normal position.

Further, information about the occupation of each of all blocks in the area 10 and its reservation information, all turnout instruction information and its reservation information, and all switch statuses are managed with a single signaling message, and the signaling message is circulated between on-board devices of all trains traveling in the area and all switch devices in the area.

Although the signaling telegram can manage the information described above with each form, in the present embodiment, as in FIG 4 shown, the signaling message by using a range identification column 211 , a member list column 212 , a block occupation column 213 , a block occupation reservation column 214 , a turnout instruction column 215 , a turnout instruction reservation reservation column 216 and a switch status status column 217 managed.

The area identification column 211 Contains the identification data of the area under the control of the signaling telegram. The members list column 212 contains a list of devices allowed to circulate in the signaling message and the circulation order thereof.

The block occupation column 213 contains identification information of trains, each of which has the right to occupy the block. The right to populate the block is what is required for a train to enter a block. Only a series of moves can secure the right to occupy the block with respect to a block. In a case where the signaling telegram is received, unless there is writing by another train, it is possible to secure the right to occupy the block by writing identification information of a host train.

The block occupation reservation column 214 contains identification information of a train that has reserved the right to occupy a block. In a case where a signaling message is received, if the right to occupy the block can not be secured because a letter of another train exists, it is possible to have the right to occupy the block by writing identification information of a train in the block occupation reservation column to reserve. When the right to populate the block is released, this reservation is executed by rewriting the train's identification information written to the reservation column to the block occupation column corresponding to the reservation column by the on-board device that has released.

In the turnout instruction statement column 215 are written by the on-board device of the train having the right to occupy the block to which the switch belongs, the instruction information for instructing the position for the switch. The switch controller reads the instruction column and locks the switch according to the instruction.

In the turnout instruction reservation reservation column 216 are written by the on-board device of the train, which has reserved the right to occupy the block to which the switch belongs, the instruction reservation information for reserving the position instruction for the switch. If the right to populate a block to which the switch belongs is released, that reservation is made by rewriting the switch instruction written to the reservation column into Turnout instruction column corresponding to the reservation column executed by the on-board device that has released.

The switch status status column 217 contains information about the state of the switch through the switch controller. Normal position lock is written in the case when it is locked in a normal position, lock in the shifted position is written in the case when it is locked in a folded position, and no lock is written in the case of changeover or in other cases. When a signaling message is received, the on-board device can check the blocking position of the switch by checking the switch position status column.

Hereinafter, a configuration in which the signaling security system of the present embodiment, distance control of the train, exclusive control, and configuration control of a route in a control area is realized by using a case as an example in which a train 1 on a track 15 , in the 3 shown drives. In addition, the content of the signaling telegram is in each step in 5 shown.

Step 1: When the train 1 on the route 15 drive, secures the on-board device 101 on the train 1 mounted, the right to occupy the block of blocks 11 . 12 and 13 in the block occupation column of the received signaling message 201 , writes a position change instruction for a switch 3 on the route in the turnout instruction column of the received signaling message 201 and transmits the signaling telegram 201 to a subsequent device.

Step 2: The point control device 103 initiates the implementation of the switch 3 to a normal position based on the turnout instruction information included in the turnout instruction column of the signaling telegram 201 are written when the signaling telegram 201 Will be received.

Step 3: Thereafter, the point controller checks 103 the status of the switch 3 every time the signaling telegram 201 is received, and in the case where the diverter is locked to a normal position, the diverter status column is written to the diverter 3 of the signaling telegram 201 is locked in the normal position.

Step 4: Additionally, if the signaling telegram 201 to the on-board device 101 is circulating, checks the on-board device 101 that the switch 3 is locked in the normal position, and allows the train 1 , on the route 15 to drive.

When a signaling message is exchanged, it is necessary to use the procedure capable of ensuring that the message has been securely transmitted to the other party, thereby avoiding possible interruption or disturbance of radio waves and falsification, copying and loss of data , This procedure includes encrypting and decrypting the message, adding sequence numbers and chronological information, checking the communication time, pre-checking and subsequent checking of the send and receive ends, replying to the data and verifying the validity of the data by error detection code for the data.

Next, the signaling security system of the present embodiment will be described by taking a case as an example in which a first train on an in 3 shown route 15 and then a second train on a in 3 shown route 16 The signaling security system is configured such that, in a case where multiple trains will travel in sequence on a non-simultaneous route, after a first train has cleared the right to occupy a non-concurrent block, regardless of the order of circulation of the signaling telegram, the switch control means with the switchover of the switch to the blocking position of a route on which the second train is traveling, based on the change instruction of the signaling telegram, which is received the first time can begin. In addition, the content of the signaling telegram is in each step in 6 shown.

First, the configuration, until the train 1 on the route 15 the same as steps 1 to 4 as described above.

Next, the operation of the system will be described in a case where the train 2 on the track 16 the right to occupy the block and turnout instructions is reserved, and this right and instructions are provided by an on-board device operating on the train 1 is mounted, activated.

Step 5: The on-board device 102 on the train 2 is mounted, checks the right to occupy the blocks 14 . 12 and 11 if the signaling telegram 201 Will be received. As a result, the right to occupy the block 14 secured, but the right to occupy the blocks 12 and 11 that by the train 1 is secured, can be secured. In this case, the on-board device reserves 102 the right to populate the block by writing the identification information of the host train into the block occupation reservation columns of the block 12 and the block 11 , In addition, a switch-over change instruction is made in the turnout instruction reservation column 2 leading to the block 12 belongs, reserved.

Step 6: After the back end of the train 1 on the track 1 drives, the block 11 has left the on-board device 101 the right to occupy the block 11 free, if the signaling telegram 201 is received, checks the reservation column, writes the identification information of the reserved train 2 into the block occupancy column, clears the identification information of the train 2 in the reservation column of the block 11 and transmits the telegram to the subsequent device. In addition, it is not necessary to provide the identification information of the train 2 in the reservation column of the block 11 and if the same identification information of the train in the block occupation column and the reservation column of the block 11 may be configured, another train or the turnout control device may be configured to delete the identification information written in the reservation column.

Step 7: Similarly, after the rear end of the train 1 the block 12 has left, as in 7 shown, the on-board device 101 the right to occupy the block 12 free, if the signaling telegram 201 is received, checks a reservation column accompanied thereby, writes the identification information of the reserved train 2 into the block occupation column and clears the identification information of the train 2 the reservation column of the block 12 , In addition, the turnout reservation column becomes the turnout 3 leading to the block 12 is checked, the instruction for the reserved lock position on the folded position is in the turnout instruction column of the switch 3 The turn position instruction is written in the turnout instruction reservation column of the switch 3 cleared and the signaling message becomes the switch controller 103 , which is a subsequent device, transmitted. In addition, it is not necessary, the lock position instruction of the switch 3 or clearing the stowed position inhibited instruction, and when the same turnout instruction is written in the turn inhibit instruction column and turn inhibit instruction reserving column, another train or the turnout control means may be configured to clear the identification information written in the turnout instruction reservation column.

Step 8: If the signaling telegram 201 is received, initiates the switch control device 103 the implementation of the switch 3 to a commanded assigned turnout position and updates the turnout status column of the signaling telegram 201 unlocked.

Step 9: After the conversion to the folded turnout position of the switch 3 and the locks are completed, the point controller updates 103 the switch position status column of the signaling telegram to a folded blocking position, and the on-board device 102 that she has received allows the train 2 , on the route 16 to drive.

That way, in terms of the train 1 on the track 15 drives, and the train 2 who is trying on the track 16 to drive, the distance control of the trains, the exclusivity control and configuration control realized. In particular, activated in step 7, since the on-board device 101 on the train 1 is mounted, not the on-board device 102 that on train 2 is mounted, the reservation of the blocking instruction for the switch 3 for the train 2 accompanied by the release of the right to occupy the block 12 , Even if the signaling telegram 201 is circulated in the order in such a way that the signaling telegram 2β1 is circulated through the on-board device 102 is circulated before passing through the turnout control device 103 is circulated, the point control device 103 the implementation of the switch 3 on a switch, through the on-board device 102 is specified based on the signaling message received the first time.

In addition, although it is described that two on-board devices and a single point control device exist in one area in the present embodiment, three or more on-board devices or point controllers may exist. Besides, it may, though an area 10 divided into four blocks, be possible the area 10 to subdivide into five or more blocks. Although all block occupation rights, lockout instructions to all switches and status information are managed in a single signaling telegram area, management may be performed with multiple signaling telegrams if content to be managed is not duplicated.

In the case of applying the signaling security system of the present embodiment to a route in which high density trains are operated, since a number of the on-board devices or point controllers exist in one area and a signaling message is circulated among these devices, one time is the signaling telegram among the devices to circulate, longer as the number of devices increases. Even in the above case, the signaling security system of the present embodiment activates the reservation of the block occupation by an on-board apparatus of a following train and the reservation of the conversion instruction to a switch belonging to a route thereof accompanied with the release of the right to occupy the block by one Thus, irrespective of the circulation order of the signaling telegram, the switch control means may begin to translate the switch to a position of a following train at a time when the signaling telegram is received for the first time. That is, in the case of operating a number of trains, it is possible to shorten an operating distance thereof and to operate the trains at a high density.

Although it is described that a single reservation column is provided in a telegram in the present embodiment, it may be possible to provide multiple reservation columns with different priorities and to activate the reservation execution of a reservation column with the highest priority and to increase the priorities of the other reservation columns by releasing the right to occupy the block of a previous train.

In addition, the present invention is not limited to the above-described embodiments and includes various modification examples. The above-described embodiments describe in detail the present invention so that it can be easily understood, and the invention is not necessarily limited to the one in which all the configurations described above are provided.
