The signal security system of this embodiment will be described with reference to FIG. FIG. 1 shows a situation in which a train not equipped with an on-board security device corresponding to the signal security system enters the control section of the signal security system that performs exclusive control of the train by the security message as shown in the background art. Showing. In the present embodiment, the train to be loaded will be described as a train equipped with an ATS-P type on-board safety device, but the train will be based on the train control information transmitted from the ground siding etc. laid on the track. Any device may be used as long as it is a device for controlling the. This system includes a security telegram 1, a train 2a, a train 2b, a train 2c, a ground management device 3, and a ground wire 4.

First, the security telegram 1 will be described. In the signal security system using the security telegram 1, the route in which the train within the control range travels is divided into a plurality of predetermined control areas, and one control area is further divided into a plurality of blocks. In this embodiment, as shown in FIG. 2, the entire route is divided into three areas 100, 200, and 300, and the area 200 is divided into four blocks 201, 202, 203, and 204. To divide.

Then, the occupation range information of all the trains traveling in the area 200 is managed by one security telegram 1, and this safety telegram 1 is circulated among the devices in the area. The security telegram 1 may manage the above information in any configuration, but in the present embodiment, as shown in FIG. 3, an area identification column 11, a member list column 12, and a block occupation right column 13 are used. explain.

In the area identification column 11, identification information of the area managed by the security telegram 1 is entered.

In the member list column 12, the identification information of the device that circulates the security telegram is entered. Each device circulates the security telegram according to this member list. That is, the device that received the security message sends the security message to the next device on the member list, and the last device on the member list sends to the first device on the member list.

In the block occupation right column 13, the identification information of each train and the occupation range information in the area secured by each train are entered. The occupancy range information may be managed in any configuration such as an absolute position or a relative position from a predetermined reference point, but in this embodiment, the occupancy right is managed for each block. Secure the exclusive right by writing train identification information in each block. In other words, the block occupancy right must be secured in order to enter the block, and only one train can secure one block, and each train can only secure the occupancy right. You can enter the block.

Next, the train 2a and the train 2b will be described. Trains 2a and 2b are equipped with on-board security devices (hereinafter referred to as train security devices 20) compatible with the signal security system using security telegrams, and transmit/receive the security telegram 1 using radios 21a and 21b. I do. When the train security devices 20a and 20b receive the security telegram 1, the train security devices 20a and 20b enter identification information indicating their own trains in the column corresponding to the entering block of the block occupation right column 13 and run in the block where the occupation right is secured. However, the train is controlled so that it will not go outside.

Next, the train 2c will be described. The train 2c is equipped with an ATS-P type on-board security device (hereinafter referred to as on-board signal device 22), a transmission/reception unit 23, an on-board child 24, and a display 25, and is used for a train security system using a security telegram. The on-board wireless device 26, the second display 27, and the wireless device 28 are installed. In the present invention, it is an object to utilize the on-board signal device 22 for the ATS-P type signal security system without modifying the on-board signal device 22, the transmitting/receiving unit 23, the on-board child 24, and the display 25. Is a device for a signal security system before boarding, in the case of the present embodiment, an ATS-P type on-board security device is used, and between the on-board signal device 22 and the transmission/reception unit 23, The upper wireless device 26 is connected.

First, as a premise of the present system, the on-board signal device 22 and the transmission/reception unit 23 mounted on the train will be described. The on-board signal device 22 mounted on the train 2c creates a speed check pattern based on the instructed stop point based on the input train control information such as distance information to the stop point, It is a device that displays information necessary for driving to the driver through the display 25 based on the check pattern and controls the train. Specifically, the train position is calculated by integrating the speed information input from the speed sensor provided in the train, and when the running speed of the train approaches the speed check pattern, the driver is alerted via the display 25. When the traveling speed of the train exceeds the speed check pattern, the brake of the train is operated via the relay section provided in the train. The speed check pattern indicates an allowable speed at which the train can stop up to the stop point. As an example thereof, FIG. 4 shows a speed check pattern 6 of the train 2c with the stop point 5 as a base point. Although the ATS-P type on-board signaling device is presupposed in the present embodiment, the ATS-P type on-board signaling device is originally provided from the transmitter/receiver to the identification number of the ground child or from the ground child to the stopping point. An ATS-P telegram containing distance information and the like is received and used for control. However, in the present embodiment, similar information is received from the on-board wireless device 26 in the same format as the ATS-P message, and this is used for control. This is different from the existing automatic train stop system.

The transmission/reception unit 23 is a device that receives a signal from the ground element 4 via an on-board element 24 that is electromagnetically coupled to the ground element laid on the track. Although this embodiment is premised on the ATS-P type transceiver, the ATS-P type transceiver originally has an ATS-P including an identification number of the ground element and distance information from the ground element to the stopping point. It receives a telegram and outputs this telegram to the ATS-P on-board device. However, in the present embodiment, the ATS-P telegram received from the ground wire 4 via the onboard wire 24 is output to the onboard wireless device 26. This is different from the existing automatic train stop system.

The on-board wireless device 26 receives distance information from the ground management device 3 to the stop point with each ground child as a base point via the wireless device 30 and the wireless device 28, stores this information, and stores it on the ground. When a child passage is detected, that is, when a signal is input from the ground child 4 through the car child 24 or the transmission/reception unit 23, the distance information from the information to the stopping point with the ground child as the base point is displayed. It is extracted and is output to the onboard signal device 22 together with the identification number of the ground element. At this time, the on-board wireless device 26 extracts the train control information based on the passing ground element from the information which is transmitted from the ground management apparatus 3 in advance and is already stored, so that the train operates the ground element. After passing, the train control information is not communicated with the ground management device 3 to receive the train control information based on the ground controller. With this mechanism, the onboard signaling device 22 can execute the train control based on the train control information with the ground element as a base point without a time lag from the passage of the ground element.

At that time, the on-board wireless device 26 transmits the identification number of the train 2c and the identification number of the passing ground child to the ground management device 3 via the wireless device 28 and the wireless device 30, and further, the ground child device The distance information from the vehicle to the stop point is displayed to the driver via the second display 27. For example, the information that "the stop point is from the ground element XX to XX meters" is displayed.

When the on-board wireless device 26 receives information from the ground management device 3, the information about the ground element passed immediately before included in the information, that is, the distance to the stop point with the ground element passed immediately before as the base point. If the information has changed from the information output to the on-board signal device 22 when passing through the ground, it can be seen that the position of the stop point has been updated due to changes in the position of the preceding train. Therefore, when such information is received, the driver is notified via the second display 27 that the position of the stop point will be updated when the next ground element is passed. For example, below the information described in the preceding paragraph, the information that “the stop point is from the ground element XX to XX meters (the pattern is updated when the next ground element passes)” is displayed.

In addition, when the on-board wireless device 26 is set to control as an existing signal device, or in the information received from the ground management device 3, train control information based on the passing ground element is included. If not, the signal input from the ground element 4 via the on-board child 24 and the transmitting/receiving section 23 is directly output to the on-board signal device 22. At this time, the on-board signaling device 22 controls as an existing signaling device, so that the on-board signaling device 22 can be safely driven even in a section where the signal security system is ATS-P. The setting for controlling as such an ATS-P type on-board security device may be performed by any method, and may be instructed wirelessly from the ground management device 3, or an operator equipped with an external interface such as a switch. You may be able to set from.

Next, the ground management device 3 will be described. The ground management device 3 participates in the circulation of the safety telegram 1 and transmits/receives the safety telegram via the wireless device 30. Also, from the on-board wireless device 26, the identification number of the ground train passed by the train 2c equipped with the device is received, and based on this information, the block in which the train 2c is present when the safety telegram is received. , And the train 2c in the block occupation right column 13 of the block on the traveling direction side of the train 2c.

Specifically, the position of the ground wire on the route, the connection relationship of each block, and the data of the block length are stored, and the ground wire passed by the train 2c, the train length of the train 2c, and the direction of travel Determine which block is present and secure the exclusive right to that block. The train length may be transmitted from the on-board wireless device 26, or the ground management device 3 may store the train length of each train and store the train identification number transmitted from the on-board wireless device 26. You can use it to refer to, or you can use the maximum length of the train that runs on the route without data. At that time, it is desirable to consider the distance from the top of the train to the mounting position of the train car. The traveling direction of the train may be transmitted from the on-board wireless device 26, or the ground management device 3 may store the ground elements passed by each train and make a determination based on the positional relationship with the ground elements. Good, if the driving direction of the track is fixed, use that direction.

Regarding the block on the traveling direction side of the train, when the security telegram 1 is received, the block occupancy right column 13 is confirmed, and the occupancy right of the block other than the train 2c does not secure the occupancy right is secured. At this time, it may be automatically secured, may be secured in accordance with an instruction from an external device such as an operation management device, or may be secured in advance according to the time when the train has a database and a train passes.

Then, the ground management device 3 determines that the block in which the exclusive right is secured in the block exclusive right column 13 is a runnable block, and determines the length from each ground element to the end point of the block in which the exclusive right is secured in the traveling direction. Then, the distance is calculated by further subtracting a predetermined margin distance from the calculated length. This allowance may be based on the value of an existing automatic train stop system, or may be determined in consideration of external conditions such as the braking performance of the train, response time, and weather. Of course, the on-board wireless device side may take into consideration the margin distance. This calculation is performed for all the ground elements, and the result is used as the distance information to the stopping point with each ground element as a base point, and the on-board wireless device 26 mounted on the train traveling on the route is provided with a wireless device. Send via 30.

Next, the ground element 4 will be described. The ground element 4 may be an unpowered ground element, and transmits information for specifying the position of the train on the train to the electromagnetically coupled car element.

By operating each device as described above, for example, in the situation of FIG. 5, the ground management device 3 writes the train 2c in the columns of the blocks 201 and 202 of the block occupation right column 13, and the train of the train 2c. By controlling the upper signaling device 22 so as not to move out of the block in which the exclusive right is secured, it is possible to control so that the train 2c does not enter the block in which the train 2a and the train 2b have the exclusive right. It is possible to prevent other trains from entering the block in which the train 2c has the exclusive right and is running.

In this embodiment, wireless communication is used for the communication between the ground management device 3 and the onboard wireless device 26, but the method is not limited. Alternatively, satellite communication using an artificial satellite, telephone line communication using a mobile phone, or the like may be used.

Further, train protection information or track closure information for restraining the train from entering or making an emergency stop may be added to the security telegram 1, and the ground management device 3 may specify a block in which the train can travel, including such information. ..

In the present embodiment, the description has been given in the area in which no troller exists, but similar control can be performed in the area 300 in which a block including a troller exists as shown in FIG. As shown in FIG. 7, in the area including the turning device, a turning device control device 7 for controlling the turning device is installed.

The security telegram 1 is provided with a roll device direction indication column 14 and a roll device direction state column 15. In the rolling device direction instruction field 14, the train or the ground management device 3 that secures the occupancy right of the block including the rolling device is a switching instruction of the rolling device (a conversion instruction to the localization/reverse position). ) Is entered. The rolling device control device 7 switches the rolling device according to the instruction of the rolling device direction instruction field 14.

In the rolling device directional state column 15, the rolling device control device 7 writes the directional state of the rolling device (stereolocking/counterlocking/unlocking). The train and the ground control device recognize the opening direction of the rolling device by confirming the rolling device direction state column 15.

When the ground management device 3 secures the occupancy right of the block including the rolling device, it updates the rolling device instruction information column 14 and instructs the rolling device control device 7 to switch the rolling device. .. In addition, the ground management device 3 determines a block in which the train 2c can travel from the states of the block occupation right column 14 and the rolling device instruction state column 15. Specifically, if the conversion of the rolling device has been completed, the block including the rolling device is determined as a block in which travel is possible. After that, the same processing is performed as in the area where there is no rolling device.

By doing this, even in an area with a turning device, as in the area without a turning device, the train 2c without the on-board security device for the signal security system using the security telegram can be safely installed. Can be run.

The instruction to switch the turning device by the ground management device 3 may be determined according to an instruction from an external device such as an operation management device, or may be determined in advance according to the time when the train has a database and passes by a train. However, it may be determined from the status of the block occupation right column 13.

Also, the ground management device 3 has been described as always participating in the circulation of security telegrams. However, when the train 2c attempts to enter the area, it participates in the circulation of security telegrams, and after the train 2c leaves the area You may be allowed to leave the circulation of the message. To participate in the circulation of security telegrams, the ground control device 3 notifies the onboard safety devices of trains that may travel in the area and the switch control devices in the area of the safety telegrams of the area. The on-board security device or the switch control device, which has transmitted the additional request message in which a request to add the identification information of the own device to the member list is transmitted, receives the additional request message, and the member list column 12 This is done by adding the identification information of the ground control device to. Moreover, when the safety management message is removed from the circulation, the ground management device deletes its own device from the member list when the security management message is received. In this way, by participating in and withdrawing from the safety bulletin, if the ground control device 3 breaks down without a train operating in the area, the circulation of the safety telegram will stop. You can prevent it.

Further, in FIG. 7, the ground control device 3 and the rolling device control device 7 are separate devices, but they may be the same device. In this case, even if one of the switch control devices 7 fails, it is possible to transmit/receive the train control information based on the identification number of the ground coil or the ground coil to/from another non-failing switch controller 7. For example, you can drive in the area.

In addition, when the ground control device 3 recognizes that the troll control device is excluded from the circulation of the telecommunication message due to a failure or the like when receiving the telecommunication message, the telecommunication device control device controls. The block including the rolling device may be recognized as being inaccessible and may be excluded from the blocks that can run.

Next, the control operation of the train control information transmission system of the present embodiment will be described. FIG. 8 is a flowchart showing an example of processing operation executed by the on-board wireless device 26.

Step 413: From the distance information to the stop point with each ground element as the base point stored in step 411, the distance information to the stop point with the ground element passed immediately before as the base point is extracted, and the process proceeds to step 414.

Step 414: The information extracted in step 413 is compared with the distance information to the stop point based on the same ground element output to the onboard signaling device 11 in step 425 described later, and if there is a difference, step 415 If there is no difference, the process returns to step 401.

Step 415: The information extracted in step 413 is displayed on the second display 27. For example, under the information displayed in step 426, which will be described later, the information "the stop point is from the ground element XX to XX meters (the pattern is updated when the next ground element passes)" is displayed, and the process returns to step 401.

Step 421: The signal from the ground element 4 is stored, and the process proceeds to step 422.

Step 422: If the on-board wireless device 26 is set to control as an existing signaling device, the process proceeds to step 424, and if not, the process proceeds to step 423.

Step 423: The identification number of the ground element is recognized and stored from the signal from the ground element 4. The information stored in step 411 is searched, and if the information on the distance to the stopping point with the passing ground element as the base point is included, the process proceeds to step 425, and if not, the process proceeds to step 424.

Step 424: The signal from the ground element 4 is directly output to the on-board signal device 22, and the process returns to step 401.

Step 425: Output the identification number of the ground element that has passed and the distance information to the stop point with the ground element extracted in step 423 in the same format as the ATS-P message to the onboard signaling device 22, and Proceed to 426.

Step 426: The distance information to the stop point with the ground element as the base point extracted in step 423 is displayed on the second display 27. For example, the information "the stop point is from the ground child XX to XX meters" is displayed, and the process proceeds to step 427.

Step 427: The identification number of the passed ground child is transmitted to the ground management device 3, and the process returns to step 401.

FIG. 9 is a flowchart showing an example of processing operations executed by the ground management device 3. The present flow chart will be described on the assumption that the ground control device 3 is installed in an area having a troller.

Step 501: The ground management device 3 stores the position of the ground element on the route, the connection relationship of each block, and the block length data.

Step 502: When the information from the on-board wireless device 26 is input via the wireless device 30, the train identification number, the identification number of the ground child that the train has passed through, and the traveling direction of the train are stored, and step 503 is performed. Proceed to. It should be noted that the process may proceed to step 503 at regular intervals. In that case, it is possible to process a plurality of pieces of information input during that time, set a processing timer or the like, and check the soundness of the apparatus.

Step 503: Position of the ground element on the route stored in step 501, connection relationship of each block, block length data, train identification number stored in step 502, identification number of passed ground element, traveling direction of train Based on, determine which block the train is in.
