Abstract:

Targeting the new generation of launch vehicles, meeting the requirements of compact launch control system equipment and low signal response delay, a heterogeneous architecture combining FPGA and CPU is proposed to achieve redundant design and performance upgrade of the ground launch control system of the new generation of carrier rockets. Through the modular redundancy design based on multi-channel M-LVDS bus, and the construction of a competitive duty mechanism and redundancy switching mechanism with embedded main control modules, high-speed interconnection and redundant control output of various modules in the core equipment of the transmission and control system are achieved. Build an equivalent testing environment for the transmission and control system, verify the functions and performance of each single machine and module in the system. The results of the equivalent testing show that the redundancy switching function of the system is normal, the signal response time can reach up to microseconds, and the modular replacement time is within one minute. Compared with traditional system solutions, this system has the advantages of high integration, fast response speed, and convenient maintenance.
