In the new generation launch vehicle, PLCs(Programmable Logic Controller System) are deployed at the front and rear ends of the test and launch control system to achieve remote control. In this paper, a hot-standby redundancy PLC control system is designed. It uses PLC redundancy, control and monitor computer redundancy, network redundancy and control channel redundancy to realize the hot-standby redundancy of PLC launch and control system. It has been found that the hot-standby redundancy PLC control system can improve the reliability of rocket's launch control.
