Component Design of A New On-Board Control and Diagnosis System
Abstract：The new on-board control and diagnosis system component is an important unit equipment in the on-board control and diagnosis system of high-speed maglev narrow vehicle body. Its function is to send the safety related control instructions from the on-board safety computer to the vehicle subsystem, and feed back the status monitoring signal sent by the subsystem to the on-board safety computer. In order to ensure the safe and reliable operation of the control and diagnosis system, the components of the new on-board control and diagnosis system adopt redundant architecture and modular design to form a dual redundant architecture, which makes the equipment highly stable and simplifies the circuit design. It can also carry out logic function debugging and fault diagnosis through programming and diagnosis software.
Key words：redundancy Programmable Logic Controller
