Abstract

The invention relates to a simulation device for network control logic verification of a motor train unit, and belongs to the technical field of traffic control. The simulation device comprises first and second master controllers, a wire train bus simulator, a driver operating interface host, first and second protocol converters, and first and second simulation computers. The master control unitsof the device are realized by adopting a high-performance floating point digital signal processor (DSP) of target identification (TI) and mount two multifunctional vehicle buses respectively; a wire train bus is realized through a simulator to connect the two multifunctional vehicle buses, and realizes data transceiving function under a wire train bus protocol on the interior; the interaction of the master control units and the motor train unit equipment is realized by adopting an Ethernet, a personal computer (PC) machine is further accessed to the Ethernet through an Ethernet card, and conversion of a multifunctional vehicle bus protocol and an Ethernet protocol is realized in the PC machine; and finally, the PC machine of the simulation motor train unit equipment is accessed to the Ethernet. The device has high verification efficiency, strong reusability and low cost, and is convenient to maintain.

Description

Technical field [0001] The invention relates to a simulation device used for verification of the network control logic of an EMU, belonging to the technical field of traffic control. Background technique [0002] The EMU integrates many components such as machinery, electricity, electronics, control units, and pneumatic devices. It is a high-speed rail vehicle and a very complex large-scale electromechanical equipment. Compared with power-concentrated trains, power-distributed high-speed EMUs disperse the power wheels driven by motors in multiple carriages, so there are numerous electrical equipment, complex equipment structures, and diverse electrical characteristics. The train network control system is a distributed system with high reliability and high safety application requirements. It manages the main equipment on the train by collecting information and transmitting commands to provide technical guarantee for the safe operation of high-speed EMUs. The EMU train network con...
