Embodiment 1
[0030] Such as figure 1 As shown, the real-time early warning guarantee and data diagnosis method of the high-speed maglev train suspension system and the system operation flow chart take the three-module train as an example. The vehicle-level communication forms a vehicle network through the 6-TRDP protocol, including 8-Ethernet communication, 11-protocol Processing; the logic functions between devices are connected through 4-CPU central processing unit, CPU central processing unit through 12-protocol conversion, 15-logic processing, 10-health prediction, 3-safety guidance, 5-warning control, 20- The light display control function cooperates with the equipment communication network dominated by the 22-CAN bus, including 13-protocol processing, 1-frame recognition, and 9-CAN communication functions, and triggers the 24-data recording unit after data processing by the CPU. Including 14-data recording, 17-data storage, 2-data export functions, and record and store the data as re...
Embodiment 2
[0032] Such as figure 2 As shown, since the suspension node module has the characteristics of independent control, the entire suspension system is supported by several sets of independently controlled suspension units, each suspension control is independent of each other, and each 3-suspension node uses acceleration and gap sensors to form a closed-loop control system. The 5-MSU takes the suspension unit as the object, communicates and connects each suspension node through the 1-CAN bus, and monitors and records the control data and information of the suspension node. The local area network of the suspension monitoring unit adopts the CAN bus of the controller local network. Each vehicle adopts 1 MSU unit, provides 4 independent CAN communication interfaces, has CAN bus data communication capability, can monitor the status data of multiple groups of suspension nodes at the same time, and connects to 2-guided control unit through CAN bus. At the same time, through the 4-ETH ...
Embodiment 3
[0034] Such as image 3As shown, the real-time early warning guarantee and data diagnosis method and system of the maglev train suspension system are divided into 4 functional structural areas, the 3-power supply block realizes the voltage DC conversion function through the 9-power supply module; Frame identification, 10-CAN communication function; 11-CPU block realizes 5-logic processing, 16-protocol processing, 7-warning control, 12-safety guidance, 8-data recording and storage, 14-data analysis through the central processing unit module Function; 4-vehicle communication block realizes 17-Ethernet communication, 2-protocol processing, 15-logic processing, 1-protocol conversion functions through the switch board module.
