[0002] At present, with the upgrade of rail transit signal systems, train control systems based on vehicle-to-vehicle communication are widely used because they can achieve autonomous resource management and active interval protection of trains while reducing equipment deployment, and improve train operation efficiency. Traditional signal systems calculate the position and movement authorization of trains on the line based on the trackside axle counter occupancy information and the train precise positioning information calculated by the on-board controller. When the train is degraded and communication is lost, backup tracking is performed based on the axle counter occupancy information. In the vehicle-to-vehicle communication system, since there is no axle counter equipment, when the train is degraded and communication is lost, the train’s position information on the line cannot be located, and backup tracking cannot be performed.

[0003] After searching, Chinese patent publication number CN117719564A discloses a backup positioning method for TACS system, which specifically discloses S1, the backup positioning device is powered on and the configuration information is initialized; S2, the train backup positioning device periodically sends an inquiry message to the trackside train controller, asking the trackside train controller whether it needs to send backup positioning information to it; after receiving the reply information from the trackside train controller, stop sending the inquiry message and enter the S3 step, and stop sending the inquiry message after the sending timeout and enter the S5 step, etc. However, this existing patent cannot quickly locate the position of the train on the line. Therefore, how to quickly locate the position of the train on the line in the vehicle-to-vehicle communication system, especially how to display the train positioning information in the human-machine interface after the train is downgraded to a non-communication train, has become an urgent problem to be solved. Summary of the invention

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0042] like Figure 1 As shown, a train positioning display system for train-to-train communication includes the following modules: a train gateway interface module 1, a train master control server module 2 and a train information display module 3;

[0043] The train gateway interface module 1 establishes communication with the main train positioning system, the standby train positioning system, the trackside train positioning system, and the backup train positioning system according to the system data, and receives train status information from these train positioning systems and sends it to the train master control server module 2;

[0044] The train master control server module 2 receives train information from the train gateway interface module 1, performs logical processing on the train controller information, calculates the train precise positioning, imprecise positioning, occupied equipment, mobile authorization, and manual protection path information, and sends the information to the train information display module;

[0045] The train information display module 3 receives the train positioning information and displays the running status information of the train on the line in the human-machine interface;

[0046] The train gateway interface module includes the following steps:

[0047] Step 100, define the train identifier as Train, define the main train positioning system as NCC, define the backup train positioning system as BCC, define the trackside train positioning system as WTC, and define the backup train positioning system as BLS;

[0048] Step 101: Establish a link relationship between each train and the train positioning system<Train,NCC,BCC,WTC,BLS> ;

[0049] Step 102, establish the priority order of each train positioning system as NCC-BCC-WTC-BLS, where NCC is the high priority and BLS is the low priority;

[0050] Step 103, establishing a network communication connection with NCC, BCC, WTC, and BLS according to the link relationship, and receiving a train information message from the train positioning system;

[0051] Step 104, such as Figure 2As shown, if the train positioning information is received from the NCC, the positioning information includes the precise positioning of the train and the authorized distance of the train movement, and the train master control type is set to the NCC control type;

[0052] Step 105: If the NCC has no information, the train positioning information is received from the BCC, the positioning information includes the precise positioning of the train and the authorized distance of the train movement, and the train master control type is set to the BCC control type;

[0053] Step 106: If there is no information in the BCC, the train positioning information is received from the WTC, the positioning information includes the train's imprecise positioning and the train's manual protection path, and the train's main control type is set to the WTC control type;

[0054] Step 107, if there is no information in WTC, the train positioning information is received from BLS, the positioning information includes the position of the train head, and the train master control type is set to BLS control type;

[0055] Step 108, if there is no information in the BLS, set the train master control type to an unknown control type;

[0056] Step 109, sending the train master control type and train location information to the train master control server module;

[0057] The train master control server module receives the train positioning information from the gateway interface module and performs logical processing on the train controller information, including the following steps:

[0058] Step 200, establish a line equipment list, the equipment is divided into three types: track, turnout and beacon, the track and turnout equipment are connected, and the beacon is a discrete independent device;

[0059] Step 201, such as Figure 3 As shown, a track device attribute list is established, including {track ID, start point coordinates, end point coordinates, left connection device ID, right connection device ID};

[0060] Step 202, such as Figure 4 As shown, a turnout equipment attribute list is established, including {turnout ID, positioning coordinates, reverse coordinates, turnout front coordinates, positioning connection equipment ID, reverse connection equipment ID, turnout front connection equipment ID};

[0061] Step 203, such as Figure 5 As shown, a beacon device attribute list is established, including {beacon ID, coordinates};

[0062] Step 204, receiving train location information and marking the train master control type;

[0063] Step 205, when the highest priority received is NCC, BCC or WTC, search in the track equipment list and the turnout equipment list according to the train head coordinates. If the train head coordinates are between the starting coordinates and the end coordinates of the track, or the train head coordinates are between the positioning coordinates and the front coordinates of the turnout, or between the reverse coordinates and the front coordinates of the turnout, then mark the device where the train head coordinates are located as HeadDev_ID;

[0064] Step 206, search in the track equipment list and the turnout equipment list according to the train tail coordinates. If the train tail coordinates are between the track start coordinates and the end coordinates, or between the turnout positioning coordinates and the turnout front coordinates, or between the turnout reverse coordinates and the turnout front coordinates, then mark the device where the train tail coordinates are located as TailDev_ID;

[0065] Step 207, start searching from the left and right connected devices of the head device HeadDev_ID. If a turnout is found, continue searching forward according to the current position of the turnout until the tail device TailDev_ID is found. The devices passed in between are marked as a set {MiddleDev_ID}.

[0066] Step 208, set HeadDev_ID, {MiddleDev_ID} and TailDev_ID as the train positioning information occupation device set;

[0067] Step 209, when the train is controlled by NCC or BCC, search forward from the coordinate position of the locomotive according to the authorized movement distance, and search forward along the turnout position when encountering a turnout. When the search length is equal to the authorized movement distance, the search is stopped, and the searched devices are recorded as the train authorized movement device set {EOA_Device_ID};

[0068] Step 210, when the train is controlled by WTC, calculate the equipment information of the artificial protection path, search from the starting point of the artificial protection path, along the position of the turnout in the protection path to the end point of the protection path, and mark it as {Pathway_Device_ID}; and verify the imprecise positioning equipment of the train with the range of the artificial protection path. When all the imprecise positioning equipment are within the range of the artificial protection path, the train imprecise positioning is verified to be valid, otherwise the train imprecise positioning is marked as invalid;

[0069] Step 211, when the highest priority received is BLS, search in the beacon device list according to the coordinates in the backup positioning system. If the train coordinates are equal to the beacon coordinates, set the train HeadDev_ID as the beacon ID without other information;

[0070] Step 212, when all train positioning systems cannot receive train positioning information, the train is set to an unknown control type, the last calculated train positioning occupied device set is retained, and the mobile authorization device and manual protection path device information are deleted;

[0071] Step 213, the train precise positioning or non-precise positioning occupied equipment set, the mobile authorization equipment set, and the artificial protection path equipment set are sent to the train information display module.

[0072] The train information display module receives the train positioning and occupation equipment set information and displays it in the interface, including the following steps:

[0073] Step 300, such as Figure 6 As shown, all the switches and tracks of the line are drawn from left to right in accordance with the connection relationship of the line equipment;

[0074] Step 301, drawing all discrete beacon points according to the coordinates of the beacon in the line;

[0075] Step 302, when the received train master control type is NCC and BCC, the train position is drawn at the head of the train HeadDev_ID, and the precise positioning device list HeadDev_ID, {MiddleDev_ID} and TailDev_ID are set to the red occupied state. If the occupied device is a turnout, the current position of the turnout is set to red, and the position of the other direction is set to the clearing state, and the train movement authorization device is drawn in white;

[0076] Step 303, when the received train master control type is WTC, draw the train position at the tail TailDev_ID, and set the non-precise positioning equipment list HeadDev_ID, {MiddleDev_ID} and TailDev_ID to brown occupied state. If the occupied equipment is a turnout, set the current position of the turnout to brown, and the position of the other direction to clear state, and draw the train manual protection path equipment state on both sides of the track and turnout equipment;

[0077] Step 304, when the received train master control type is BLS, draw the train position at the corresponding beacon position and set the beacon to pink;

[0078] Step 305, if the train master control type is unknown, keep the previous train position unchanged, and set the corresponding positioning device list HeadDev_ID, {MiddleDev_ID} and TailDev_ID to flash in the current color, indicating that the status is unknown, and clear the status of the mobile authorization device and the manual protection path device;

[0079] Step 306: If more than two trains are occupying the same device, it will be displayed in yellow, for example, the rear of train 1 and the front of train 2 are both occupying track 2.
