[0002] As a key component of the CTCS system, the on-board equipment undertakes important functions such as receiving ground information, processing train operation instructions, and implementing train overspeed protection. Therefore, the on-board product needs to be fully tested before being put into use. However, on-board testing needs to cover various lines and various train operation scenarios, so there are many test cases to be executed. If manual testing is used, it will take a lot of time, so automatic testing is needed to improve test efficiency and test quality. Therefore, a simulation trackside system is needed to support both manual testing and automatic testing. In the process of manual testing, the tester can intuitively see the display of the route on the simulation trackside and observe the speed and position of the train on the simulation trackside. Automatic testing only needs a lightweight simulation trackside, without complex intuitive line display and train speed and position, but needs a track route data scene script corresponding to each test case.

[0003] CN113917850A discloses a software-based trackside simulation system, which includes a signal system interface module, a trackside device code bit module, a scene injection module, and a trackside device logic operation module. The signal system interface module is a software interface between the trackside simulation system and the signal system, used for communication between the two. The trackside device logic operation module is used to implement the action logic of the trackside simulation system. The scene injection module is used to simulate the set scene, including the injection of various fault scenes and the jump of the trackside device collected code bit state. The trackside device code bit module is used to collect the simulation outdoor code bit and can respond to the operation result of the trackside device logic operation module or the operation command of the scene injection module, set the specified trackside collected code bit to the corresponding state, and send it to the signal system through the signal system interface module.

[0126] (2) Trackside data editing module

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

[0132] (4) Communication module with vehicle simulator

[0133] Figure 11 The application environment diagram of the simulation trackside system of the present application, wherein the communication module with the vehicle simulator is used for communication between the simulation trackside and the vehicle simulator, and includes the following functions:

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

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

[0136] BaliseInfo: balise message;

[0137] FeedbackInfo: message receipt;

[0138] TrainChangeCabAckInfo: turn-back message receipt.

[0139] 2. The vehicle simulator sends the following data messages to the simulation trackside:

[0140] AddTrainInfo: add train message;

[0141] DeleteTrainInfo: delete train message;

[0142] TrainStatusInfo: train status information;

[0143] TrainChangeCabInfo: Turnback information.

[0144] 3. Support double-end function

[0145] The vehicle simulator communication module supports communication with the vehicle simulator simulating the front of the vehicle and the vehicle simulator simulating the rear of the vehicle at the same time.

[0146] As shown in Figure 12 , the automatic turnback includes the following steps:

[0147] Before the turnback, the simulated trackside loads the track route data file before the turnback, such as TSlinedata.xml, and judges the front and the rear, wherein the vehicle simulator receiving the add train message AddTrainInfo is the front.

[0148] The simulated trackside receives the turnback information TrainChangeCabInfo from the vehicle simulator.

[0149] The simulated trackside switches the data file to the track route data file and displays it in the train operation display module.

[0150] After receiving the train status information TrainStatusInfo sent by the vehicle simulator of the front, the simulated trackside finds the carrier frequency, the low frequency, and the transponder message TrackCodeInfo according to the corresponding information in the track route data, and sends them to the vehicle simulator of the front and the rear.

[0151] During the turnback, the simulated trackside receives the turnback message TrainChangeCabInfo reply sent by the vehicle simulator, and takes the position of the vehicle simulator sending the turnback message reply as the front, automatically changes the track route data file after the turnback (TSlinedata_for_change_cab.xml file), and displays the information in the file in the interface.

[0152] During the turnback, if the low frequency code needs to be modified, such as changing from HU code to U, it can be directly modified in the right interface shown in Figure 3 . It can also be set through the automatic test interface set_current_code(carrier_frequence,low_frequence) developed by the simulated trackside.

[0153] In a preferred embodiment, the implementation of the double-end and automatic turnback functions is as follows:

[0154] S1: Load TSlinedata.xml when simulating trackside start, at this time, send all balise messages to the vehicle simulator, or send the balise messages corresponding to the displacement to the train according to the TrainStatusInfo message package.

[0155] S2: When the simulation trackside receives the AddTrainInfo message from the vehicle simulator, the simulation trackside judges that the communication link is the head, and judges that the other IP in the configuration file corresponds to the communication link of the tail. The vehicle simulator sends the TrainStatusInfo message package to the simulation trackside during operation, and the simulation trackside sends the re-evaluation and low-frequency, balise message information corresponding to the displacement of the TrainStatusInfo message package to the vehicle simulator according to the displacement of the TrainStatusInfo message package.

[0156] Support adding a train at any position of the simulation trackside. When using track route data, the AddTrainInfo message sent by the vehicle simulator to the simulation trackside contains a displacement offset field. When the simulation trackside receives the message, it stores the displacement offset. When the TrainStatusInfo message package is received later, the displacement offset is added to the displacement in the TrainStatusInfo to reply to the carrier frequency, low frequency, and balise message, thereby realizing the effect of running after adding a train at any position.

[0157] S3: The vehicle simulator stops and stabilizes after stopping, and the simulation trackside receives the TrainChangeCabInfo information from the vehicle simulator.

[0158] S4: When the simulation trackside receives the TrainChangeCabInfo information from one of the links of the vehicle simulator, the simulation trackside judges that the communication link is the head, and judges that the other IP in the configuration file corresponds to the communication link of the tail. The simulation trackside automatically changes to TSlinedata_for_change_cab.xml, and the interface displays the information in the file (at this time, send all balise messages to the vehicle simulator, or send the balise messages corresponding to the displacement to the train according to the displacement).

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

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

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

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

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

[0164] S10: During the process of simulating running, the simulation trackside sends the frequency and the low frequency corresponding to the displacement in the TrainStatusInfo message to the vehicle simulator.
