Abstract

The invention discloses a simulation testboard for a network control system of a multiple unit train. The simulation testboard includes a KVM switching device, an Ethernet switch and multiple industrial control computers. The industrial control computers correspond to control units of a network control system of a multiple unit train one by one. Each industrial control computer is in communication connection with one corresponding control unit through a conversing device. The industrial control computers are all connected to the Ethernet switch so as to communicate with each other. The industrial control computers are all connected to the KVM switching device so as to achieve a monitoring function. The simulation testboard has the advantages of simple structure, comprehensive test, high automation, high integration, etc.

Description

Technical field [0001] The invention mainly relates to an EMU network control system, and particularly refers to a simulation test bench for an EMU network control system. Background technique [0002] Network control technology is one of the core technologies of the EMU. On this type of EMU, numerous on-board control units and on-board equipment are connected to the on-board network control system. Under the arbitration of the network control system, the traction brake control and excessive With functions such as phase control, fixed speed, and passenger information services, the network control system provides information services such as train status data, diagnostic data, and maintenance data for drivers, flight attendants, and maintenance personnel. With the continuous expansion of the application market of EMUs, in order to be able to quickly and quickly develop new EMU network control system application software, test and verify software functions and system performance, t...
