The method of claim 6, wherein the specific process of implementing sequential execution of the scene instruction set is: initializing a scene case, loading a scene case file by a program, starting a scene instruction analysis engine, reading xml nodes and data according to agreed node descriptions, and storing the xml nodes and data in an instruction structure body form into an instruction structure body list established by a memory; the instruction analysis engine program sequentially extracts instruction structures from the instruction structure list, and according to the instruction type and the instruction object member variables, for the analyzed action sentences, a corresponding interface processing function in the communication interface module is called to transfer the objects and parameters to the communication interface module for processing and packaging; and for the detection statement, calling a corresponding detection object item point interface function in the communication interface module, reading a returned item point feedback variable, and carrying out detection passing logic judgment according to the expected value to form an instruction execution condition.

8. The authentication method according to claim 7, wherein the scene authentication management unit is started while executing the initialization of the communication interface module, loading the communication interface configuration parameter file, establishing sockets for communication with various types of coset simulation models one by one according to the communication interface configuration therein, and opening the communication port; the communication interface module is called by the scene management and instruction execution module, and each time an action statement of a scene instruction is executed, a corresponding control command interface of the communication interface module is called, a control command data packet is generated and sent to a corresponding accompanying test simulation model.

9. The authentication method of claim 8, wherein the control command packet field comprises: sender ID, receiver ID, control command sequence number, control command identification, command parameter type and command parameter combination data field.

10. The method according to claim 8 or 9, wherein after the model feedback data sent by each type of test simulation model and the signal system service data sent by the urban rail signal system are received by the socket of each corresponding communication port of the communication interface module, the feedback semantic variable hash table stored in the memory area is analyzed and semantically mapped according to the agreed communication protocol;

when the scene management and instruction execution module executes the detection statement of the scene instruction, the feedback detection interface opened by the communication interface module is called, the high-efficiency positioning query characteristic of the hash table is utilized, and the required detection data is directly addressed and obtained in the feedback semantic variable hash table according to the detection object and the detection item point parameters, so that logic judgment is performed.
