Background
At present, a plurality of signal manufacturers, simulation manufacturers and research institutions develop a train control system simulation test platform for rail transit, integrate simulated vehicles, trackside turnouts, annunciator transponders and other equipment, and access the train control system, and the aim of the test is to test the functions and the performances of the train control system, including testing the functions of the train control system such as ATO (automatic train operation), overspeed protection, entering station, parking, door opening, skip parking and buckling and the like. Plays an important role in the current CBTC project construction and the corresponding product development and upgrade iteration.
However, the simulation test platform of this type has certain limitations, namely, the interface, the operation mode, the supported train control system operation mode, and the like are fixed. Train simulation, trackside equipment simulation, platform and train interface mode are a set of fixed train control system service, include the following part:
1) train simulation: and (3) simulating the train motion model and related interfaces thereof, wherein the simulation comprises but is not limited to a relay interface, an MVB interface, train speed, acceleration, traction brake models and the like.
2) Trackside simulation: and (3) simulating the trackside basic equipment, including but not limited to the simulation of signals such as a shaft counting signal, a track circuit, a turnout, a signal machine, a transponder signal, a platform door and the like.
3) A simulation integration platform: and performing integrated management on the simulation equipment and the tested equipment, such as controlling the position of the train according to the vehicle speed and the turnout state controlled by the ATO, and sending a transponder signal corresponding to the position of the train.
Because the system architecture and design are relatively fixed, the simulation test platform described above often does not support the technical verification of a new generation of train control, multi-mode train control and new functions, such as the technical principle verification of novel train control systems such as a train autonomous operation system (TACS), a multi-mode fusion train control system, online linkage de-editing and the like; therefore, how to construct a verification system which can support dynamic configuration of train position detection, speed measurement, occupation representation, turnout control, access control (part of signal systems), signal display, train operation authorization calculation and display, emergency shutdown and other specific area state indications becomes a technical problem to be solved.
