Technical Field

[0001] The invention relates to a train operation control system, and in particular to a simulated trackside system, equipment and medium suitable for on-board testing of trains. Background Art

[0002] As a key component of the CTCS system, the on-board equipment is responsible for receiving ground information, processing driving instructions, and implementing important functions such as train overspeed protection. Therefore, on-board products need to be fully tested before they are put into use. However, on-board testing needs to cover various routes and various driving scenarios. Therefore, there are many test cases that need to be executed. If manual testing is time-consuming, it is necessary to improve the test efficiency and quality through automatic testing. To this end, a simulated trackside is required that can support both manual testing and automatic testing. During the manual test, the tester can see the display of the route on the simulated trackside very intuitively and can observe the speed and position of the train on the simulated trackside; while the automatic test only requires a lightweight simulated trackside, does not require complex intuitive line display and train speed and position, etc., but requires a driving track route data scenario script corresponding to each use case.

[0003] CN113917850A discloses a trackside simulation system based on software implementation, including a signal system interface module, a trackside equipment code module, a scene injection module and a trackside equipment logic operation module; the signal system interface module is a software interface between the trackside simulation system and the signal system, and is used for communication between the trackside simulation system and the signal system; the trackside equipment logic operation module is used to realize the action logic of the trackside simulation system; the scene injection module is used to realize the simulation of the set scene, including the injection of various fault scenes and the jump of the trackside equipment acquisition code state; the trackside equipment code module is used to realize the acquisition of the outdoor code of the simulation room, and can respond to the operation result of the trackside equipment logic operation module or the operation command of the scene injection module, set the specified trackside acquisition code to the corresponding state and send it to the signal system through the signal system interface module. However, the system adopts a command-acquisition matching relationship to realize trackside simulation, which needs to be done manually and cannot realize automatic testing. Summary of the invention

[0075] This embodiment provides a simulation trackside system suitable for train on-board testing, such as Figure 1 As shown, it includes: a trackside data conversion module, a trackside data editing module, a train operation display module, a vehicle simulator communication module, and an AT communication module.

[0076] (1) Trackside data conversion module

[0077] The trackside data conversion module is compatible with route data in two formats: route data and track route data. It also supports converting route data into track route data. The conversion interface is as follows: Figure 2 shown.

[0078] The route data describes the length or position of all signal equipment in the stations and sections of the line, including track sections, signal machines, turnout positioning, and previous and next stations, and transponder messages and positions. The advantage of this data format is that, combined with the SVG format station map, the user can intuitively see the train position during the test, especially during manual testing. An example of the route data is as follows.

[0079]

[0080]

[0081]

[0082] Due to space limitations, the above are just examples. In actual data, there are multiple Stations, Tracks, Switches, Signals, Balises, and Stlinks.

[0083] The trajectory route data only retains the data required for the vehicle to pass through the route, including the carrier frequency, low frequency and transponder message corresponding to the displacement. An example of part of the trajectory route data file is as follows:

[0084]

[0085]

[0086]

[0087]

[0088]

[0089] The method for converting the current route data into the track route data is as follows: sorting out the node data of the stations, tracks, signals, switches, and station connection relationships in the current route data file to form the TCR and BTM nodes of the track route data file, thereby realizing the conversion from the current route data file to the track route data file.

[0090] Specifically, Figure 4 As shown, the following steps are included:

[0091] Step 1: Get the train's running direction, starting station and section, and set the turnout position;

[0092] Step 2: Find all the track sections that the train needs to pass through and store them in the route list, where the track sections include non-turnout sections and turnout sections;

[0093] Step 3: Find the balises of all stations in the route data file, and find out whether the track section corresponding to the balise is in the train running path in the route list according to the associated track attribute value of the balise node. If so, insert the balise into the route list;

[0094] Step 4: Form a track route data file: calculate the displacement of the track and turnout to form a new XML file TCR node, which contains the displacement and carrier low frequency; calculate the displacement of the transponder, parse the plain text message, and form a new XML file BTM node, which includes the displacement and transponder message data.

[0095] Among them, Figure 5 As shown, finding all the track sections that the train needs to pass through specifically includes the following steps:

[0096] Step 21: Searching for tracks according to the signal equipment index, station number and train running direction, wherein the signal equipment index is a unique identifier of all tracks, signals, switches and station connection relationships under a station;

[0097] Step 22: Determine whether the next track is found, if so, continue searching, if not, search for the signal according to the signal equipment index, station number and train running direction;

[0098] Step 23: Determine whether the next signal is found, if so, continue searching, if not, search for the turnout according to the signal equipment index, station number and train running direction;

[0099] Step 24: Determine whether the next turnout is found, if so, continue searching, if not, find the station connection relationship according to the signal equipment index, station number and train running direction;

[0100] Step 25: Determine whether the next station connection relationship is found, if so, continue searching, if not, end.

[0101] Among them, Figure 6 As shown in the figure, searching for tracks based on signal equipment index, station number and train running direction is as follows:

[0102] Find tracks by signal equipment index and station number;

[0103] Determine whether the track is found.

[0104] If yes, determine the direction and return the corresponding signal device index, and continue to search for tracks according to the returned signal device index and station number. If it is forward, return the next signal device index, and if it is reverse, return the previous signal device index;

[0105] Otherwise, look up the signal based on the signal equipment index and station number.

[0106] like Figure 7 As shown in the figure, the specific steps to find the signal according to the signal equipment index, station number and train running direction are:

[0107] Find signals by signal equipment index and station number;

[0108] Determine whether the signal is found.

[0109] If yes, determine the direction and return the corresponding signal device index, and continue to search for tracks according to the returned signal device index and station number. If it is forward, return the next signal device index, and if it is reverse, return the previous signal device index;

[0110] Otherwise, find the turnout based on the signal equipment index and station number.

[0111] like Figure 8 As shown in the figure, the specific steps for finding the turnout according to the signal equipment index, station number and train running direction are:

[0112] Find turnouts by signal equipment index and station number;

[0113] Determine whether the turnout is found.

[0114] If so, determine the reverse position and return the corresponding signal device index, and continue to search for tracks according to the returned signal device index and station number. If it is positioning, determine the direction. If it is forward, return the next signal device index. If it is reverse, return the previous signal device index. If it is reverse, determine whether the priority index is consistent with the previous signal device index. If so, return the signal device index corresponding to the reverse position attribute. Otherwise, return the next device signal index.

[0115] Otherwise, the station connection relationship is searched according to the signal equipment index and station number.

[0116] like Fig. 9 As shown in the figure, the station connection relationship is found according to the signal equipment index, station number and train running direction:

[0117] According to the signal device index, the associated station number, and the adjacent signal device name, the next signal device index in the station connection relationship is searched;

[0118] Determine whether the corresponding signal device is found.

[0119] If yes, determine the direction. If it is forward, return the next signal device index. If it is reverse, return the previous signal device index. Continue to search for station connection relationship according to the returned signal device index.

[0120] Otherwise, the search ends.

[0121] As shown in Figure 10, forming a trajectory route data file specifically includes the following steps:

[0122] Determine whether all signal devices have completed route data conversion. If so, generate a track route data file. Otherwise, determine the device type of the next signal device.

[0123] If the device type is track, determine the direction and generate an XML node of the track route data file corresponding to the track, where if it is forward, calculate the displacement according to the forward length attribute of the track device, and if it is reverse, calculate the displacement according to the backward length attribute of the track device;

[0124] If the device type is a turnout, determine the direction and generate a TCR node, and further determine the reverse position. If it is forward and in positioning, calculate the displacement based on the forward length of the turnout device in positioning; if it is forward and in reverse position, calculate the displacement based on the forward length of the turnout device in reverse position; if it is reverse and in positioning, calculate the displacement based on the backward length of the turnout device in positioning; if it is reverse and in reverse position, calculate the displacement based on the backward length of the turnout device in reverse position;

[0125] If the device type is a transponder, the transponder displacement is calculated based on the direction, verification direction of the transponder message, reverse offset, forward offset, and length of the track, and the plaintext message is parsed to generate a BTM node.

[0126] (2) Trackside data editing module

[0127] The trackside data editing module is used to edit track route data. Figure 3As shown, the conversion of the trajectory route data file can be edited in the interface. Compared with the text editor, this interface simplifies the editing of the trajectory route data file. In addition, this module also provides functions such as "synchronous modification of E5 / C1 packages" and "synchronous change of subsequent tcr\btm positions".

[0128] (3) Train operation display module

[0129] The train operation display module is used to display the train operation in two route data forms.

[0130] When the simulated trackside adopts the route data format, the complete station map and section map are displayed, and the train icon is displayed in the corresponding section to indicate the train position;

[0131] When the simulation trackside uses the track route data format, such as Figure 3 As shown on the left side of the figure, the train running status is displayed in the form of a table. The first column of the table indicates the train displacement. When the train runs to a certain position, the row corresponding to the position of the signal equipment ahead at that position in the table is highlighted.

[0132] (4) Communication module with vehicle simulator

[0133] Fig.11 The figure is a schematic diagram of the application environment of the simulated trackside system of the present invention, wherein the communication module with the vehicle simulator is used for simulating the communication between the trackside and the vehicle simulator, and includes the following functions:

[0134] 1. The simulation trackside sends the following data message to the vehicle simulator:

[0135] TrackCodeInfo: carrier frequency, low frequency information, etc.

[0136] BaliseInfo: balise message;

[0137] FeedbackInfo: message receipt;

[0138] TrainChangeCabAckInfo: Return message receipt.

[0139] 2. The vehicle simulator sends the following data message to the simulated trackside:

[0140] AddTrainInfo: add train information;

[0141] DeleteTrainInfo: delete train information;

[0142] TrainStatusInfo: train status information;

[0143] TrainChangeCabInfo: return information.

[0144] 3. Support dual-end function

[0145] The vehicle simulator communication module supports the simulated trackside to simultaneously communicate with the vehicle simulator at the front of the simulated vehicle and the vehicle simulator at the rear of the simulated vehicle.

[0146] like Fig.12 As shown, automatic return includes the following steps:

[0147] Before turning back, the simulation trackside loads the track route data file before turning back, such as TSlinedata.xml, and determines the front and rear of the train. Among them, the train that receives the train adding message AddTrainInfo is the front train.

[0148] The simulation trackside receives the return information TrainChangeCabInfo from the vehicle simulator;

[0149] The simulated trackside switching data file is a track route data file and is displayed in the train operation display module;

[0150] After receiving the train status information TrainStatusInfo sent by the vehicle simulator at the front of the train, the simulation trackside searches for the carrier frequency, low frequency, and transponder message TrackCodeInfo according to the corresponding information of the train status information TrainStatusInfo in the track route data, and sends it to the vehicle simulators at the front and rear of the train;

[0151] When turning back, the simulation trackside receives the return message TrainChangeCabInfo receipt sent by the vehicle simulator, and takes the location of the vehicle simulator that sends the return message receipt as the locomotive, automatically replaces the trajectory route data file after the turnaround (TSlinedata_for_change_cab.xml file), and displays the information in the file in the interface.

[0152] When returning, if you need to modify the low frequency code, such as changing from HU code to U, you can directly Figure 3 The right side interface shown is modified; it can also be set through the automatic test interface set_current_code(carrier_frequence,low_frequence) developed by the simulation trackside.

[0153] In a preferred embodiment, the double-ended and automatic return functions are implemented as follows:

[0154] S1: Load TSlinedata.xml when the simulation trackside is started (at this time, all balise messages can be sent to the vehicle simulator, and the balise message corresponding to the displacement of the TrainStatusInfo message packet can be sent to the train later).

[0155] S2: When the simulation trackside receives the AddTrainInfo message from the vehicle simulator, the simulation trackside determines that the communication link is the front of the train, and determines that the communication link corresponding to another IP in the configuration file is the rear of the train. During the operation of the vehicle simulator, the simulation trackside sends a TrainStatusInfo message packet to the simulation trackside, which includes the displacement of the train. The simulation trackside sends the vehicle simulator the message information of the re-evaluation and low frequency and transponder corresponding to the displacement according to the displacement of the TrainStatusInfo message packet).

[0156] It supports adding vehicles at any position on the simulated trackside. When using track route data, the AddTrainInfo message sent by the vehicle simulator to the simulated trackside contains a displacement offset field. When the simulated trackside receives the message, it stores the displacement offset. When it subsequently receives the TrainStatusInfo message packet, it replies to the carrier frequency, low frequency, and transponder messages according to the displacement in TrainStatusInfo plus the displacement offset, thus achieving the effect of adding a vehicle at any position and running it.

[0157] S3: After the vehicle simulator stops steadily and accurately, the simulation trackside receives TrainChangeCabInfo information from the vehicle simulator.

[0158] S4: When the simulation trackside receives TrainChangeCabInfo information from one of the links of the vehicle simulator, the simulation trackside determines that the communication link is the front of the train, and determines that the communication link corresponding to the other IP in the configuration file is the rear of the train. The simulation trackside automatically changes to TSlinedata_for_change_cab.xml, and the interface displays the information in the file (at this time, all transponder messages can be sent to the vehicle simulator, and the transponder message corresponding to the displacement can also be sent to the train later according to the displacement).

[0159] S5: The simulation trackside receives TrainStatusInfo information from the vehicle simulator.

[0160] S6: The simulation trackside finds the carrier frequency, low frequency (such as HU code), transponder message, etc. according to the configuration in TSlinedata_for_change_cab.xml and the corresponding information in TSlinedata_for_change_cab.xml and replies to the vehicle simulator.

[0161] S7: The simulation trackside receives a set_current_code information packet from the automatic test platform, for example, the set_current_code information packet has a carrier frequency of 1700-1 and a low-frequency U code.

[0162] S8: The simulation trackside receives TrainStatusInfo information from the vehicle simulator.

[0163] S9: The simulated trackside sends a carrier frequency of 1700-1 and a low-frequency U code to the vehicle simulator.
