Semi-physical simulation testing platform of train control network

Abstract

The invention discloses a semi-physical simulation testing platform of a train control network, which comprises a vehicle-mounted electrical control system, a software simulation control system and / or a physical control system and a data acquisition interactive system, wherein the software simulation control system and / or the physical control system is connected with the vehicle-mounted electrical control system; the data acquisition interactive system is connected with the vehicle-mounted electrical control system so as to convert a signal output by the vehicle-mounted electrical control system into a digital signal or convert the digital signal into an input signal required by the vehicle-mounted electrical control system; and the data acquisition interactive system is connected with the software simulation control system and / or the physical control system so as to convert the digital signal connected and output by the software simulation control system and / or the physical control system into a switching value signal or convert the switching value signal into the digital signal required by the software simulation control system and / or the physical control system. The semi-physical simulation testing platform of the train control network is capable of comprehensively implementing evaluation and verification on the design of a train network control system, eliminating possibledesign errors, rapidly positioning faults to ask for reasons, and reducing the production debugging cost and the technical risks of real trains.

Description

technical field [0001] The invention relates to a test platform technology, in particular to a semi-physical simulation test platform for a train control network. Background technique [0002] The train control network is used to control and manage almost all subsystems such as the traction system, braking system, high-voltage system, auxiliary power supply, air conditioning, driving safety equipment, doors and lighting of the train, and plays an extremely important role in the operation and maintenance of the train , and many subsystems involve multiple professional fields, not only the network communication protocol between each subsystem is very complicated, but more importantly, the logic control algorithm and fault diagnosis strategy based on network communication are also very complicated. [0003] Designing and implementing such a complex and huge system, and ensuring the safe and reliable operation of the train, is urgent both in the design and implementation of the ...

Problems solved by technology

[0008] Second, intelligent control units can only simulate part of the input and output information and diagnose faults. For complex control logic and chain reactions, manual operation of buttons or switches can only be used to create fault chains and delays. The simulation output results of the hardware simulation platform are consistent with the actual The failure conditions are quite different, and the evaluation and verification of the control system are not comprehensive

However, the pure software simulation platform needs to have a good understanding of the characteristics and behavior of the controlled object. Due to the lack of physical objects as a reference, when the simulation model does not match the actual equipment or the model parameters are incorrect, the control output of the entire simulation platform may differ greatly from the actual result. In addition, the software simulation platform cannot realize the loading and verification of hardware device programs (including firmware, database, application software), etc., and the evaluation and verification of the control system is not comprehensive
