Design of remote group control system based on thermal environment of MODBUS launch vehicle

Abstract

Aiming at the problems of the ground simulation experiment of carrier rocket, such as the large number of regions divided, the different length of the device and the different model curve, the remote group control scheme of the rocket thermal environment was designed and realized. The system takes 108 sets of AC-DC conversion power electronic devices as the main power components, uses Ethernet Modbus TCP/IP communication protocol, and applies configuration software WinCC and S7-200 Smart PLC as the execution terminal. To be realized the monitoring of 108 AC - DC conversion power electronic equipment by a computer via multi-port switch. The system has been successfully applied in a research institute in Beijing, which improves the working efficiency and ensures the reliability and stability of the operation.
