Step 120, in the active transponder mode, the signal state information is sent to the interlocking device, so that the interlocking device generates the reference transponder message information based on the signal state information.
It can be understood that the simulation system can be in communication connection with the interlocking device, the interlocking device can be entity equipment in a real track traffic scene, and the vehicle-mounted control system of the train needs to be in communication connection with the interlocking device in the real scene, the simulation system is used for simulating the communication process between the vehicle-mounted control system of the train and the interlocking device, the simulation system can send the state information of the annunciator to the interlocking device, and the interlocking device can transact a route for the train according to the state information of the annunciator, namely calculate movement authorization for the train, so that the message information of the reference transponder can be generated.
The reference transponder message may include specific information of the active transponders that the train will pass in front of, equivalent to informing which active transponders the train will pass.
It is worth mentioning that the transponders can be classified into active transponders and passive transponders according to whether the messages are changeable, wherein the passive transponders are also called fixed transponders, the active transponders can be classified into a main transponder and a filling transponder, the messages of the fixed transponders are not changeable, the main transponder and the filling transponder are arranged beside the position of the signal machine, the filling transponder is arranged outside the main transponder, and the distance between the filling transponder and the main transponder should ensure that the train does not receive the messages of the filling transponder during the speed reduction.

In an actual application scenario, the message information of the reference transponder may correspond to messages such as "red light" and "green light" of the active transponder.
And 130, receiving the reference transponder message information, and determining the active transponder message information based on the reference transponder message information.
It can be understood that the simulation system can receive the reference transponder message information sent by the interlocking device, an active transponder model and/or a passive transponder model are arranged in the simulation system, the active transponder model and the passive transponder model are software programs, the real active transponder and the passive transponder can be simulated, and the active transponder model can simulate the real process of the train to trigger the transponder according to the reference transponder message information and further simulation of the simulation system on the train running process, so that the active transponder message information is obtained.
It should be noted that, the active transponder message information is not generated by the train triggering the active transponder, but is taken as the active transponder message information in advance when the train is about to trigger the active transponder but is not actually triggered.
And 140, transmitting the active transponder message information to a vehicle-mounted interface platform so that the vehicle-mounted interface platform can simulate the train running process and the active transponder triggering process based on the active transponder message information and the real-time train position, and transmitting the first transponder message information to the train automatic protection system in real time.
It CAN be understood that the vehicle-mounted interface platform CAN be provided with a CAN channel, so that high-speed real-time transmission of data CAN be realized, the simulation system sends the active transponder message information to the vehicle-mounted interface platform, the train running process is continuously simulated in the vehicle-mounted interface platform to obtain the real-time position of the train, and the process of triggering the active transponder in the running process of the train is simulated by combining the active transponder message information and the real-time position of the train, so that the first transponder message information is generated.
The process of triggering the active transponder in the running process of the train is put on the vehicle-mounted interface platform instead of being carried out in the simulation system, because the simulation system cannot transmit the message information at a high speed in real time, and the vehicle-mounted interface platform has the capability of high-speed communication, the first transponder message information is generated in real time and sent to the ATP in the process of triggering the active transponder in the running process of the train in the vehicle-mounted interface platform, so that the simulation of the active transponder is more realistic, and the low-delay transmission of the message information of the active transponder can be realized.

In some embodiments, the transponder simulation method further comprises: determining passive transponder message information based on the state information of the annunciator in the passive transponder mode; and the passive transponder message information is sent to the vehicle-mounted interface platform, so that the vehicle-mounted interface platform can simulate the train running process and the triggering process of the passive transponder based on the passive transponder message information and the train real-time information, and the train automatic protection system can send the second transponder message information in real time.

It should be noted that, here, the passive transponder message information is not generated by the train having triggered the passive transponder, but is about to trigger the passive transponder, but when the train has not been triggered in practice, the message information in this state is taken as the passive transponder message information in advance.
Unlike active transponders, passive transponders do not need to communicate with the interlock, so the passive transponder model constructed herein does not need to receive reference transponder message information sent by the interlock, but rather generates passive transponder message information directly from the annunciator state information.
After the passive transponder message information is generated, the simulation system also sends the passive transponder message information to the vehicle-mounted interface platform, the train running process is continuously simulated in the vehicle-mounted interface platform to obtain the real-time position of the train, and the process of triggering the passive transponder in the running process of the train is simulated by combining the active transponder message information and the real-time position of the train, so that the second transponder message information is generated.

In some embodiments, the determining the active transponder message information in step 130 based on the reference transponder message information includes: and carrying out coding processing on the reference transponder message information to obtain the active transponder message information.
It can be understood that the length of the reference transponder message information can be 1023 bits, and the vehicle-mounted interface platform can transmit 823 bits, so that the active transponder model can encode the reference transponder message information, and can encode the 1023-bit reference transponder message information according to standard format requirements to obtain 823-bit active transponder message information.
In some embodiments, the receiving the reference transponder message information in step 130 includes: and receiving the reference transponder message information from the interlocking device through the ground electronic device.
It will be appreciated that in a real scene of rail traffic, the ground electronic device (LEU, lineside Electronic Unit) is a data acquisition and processing unit, connected to the interlocking device through a serial communication interface or other means of interface, periodically receives messages or information that vary in real time and is sent by the interlocking device, and continuously sends messages to the active transponder.
As the running speed of trains is continuously increased, the requirement of safe high-speed running of trains cannot be met in terms of information quantity by only transmitting blocking information to the vehicle-mounted equipment through a track circuit, and a large amount of fixed information and variable information are required to be provided for the train-controlled vehicle-mounted equipment by adding a transponder device.
The ground electronic equipment LEU can receive transponder messages sent from outside and continuously transmit the transponder messages to the transponders, and 1 LEU can simultaneously send a plurality of different messages to 4 active transponders. When the train approaches the active transponder, the message sent by the LEU should remain unchanged. The LEU should be able to monitor the status of the information channel with the active transponder in real time and send it back to the interlock in time. When the LEU fails to communicate with the interlock or the received data is invalid, the LEU should send a stored default message to the active transponder. The LEU stored messages (containing default messages) should be able to be checked by a special test tool. The LEU should be able to detect and handle random or fixed data errors that may occur in time in order to prevent compromising traffic safety. Effective security measures must be provided to ensure the timeliness of the LEU inputs and outputs. Modification of the LEU stored message should be authorized. The message-receiving LEU should be able to store default messages and must have effective security measures to ensure that the output default message is properly selected. The LEU can output the self-check and event record of the open circuit and short circuit detection information equipment and upload the self-check and event record to external equipment.
