The pre-measurement and control software is an important part of the ground measurement and control system of the carrier rocket. It is mainly responsible for the acquisition, display and control of the ground data of the carrier rocket during the test and launch. It has the characteristics of strong real-time performance, high reliability, large amount of data and complex interface relationship. Aiming at the problems of mission density normalizing in space launch, increasing test times, and increasing reliability requirements of pre-measurement and control software, a hot standby redundancy system based on heartbeat signals is studied. By setting the primary and secondary software and communicating with each other through heartbeat signals, autonomous switching of the software redundancy system can be realized in case of the failure of the primary software. The overall reliability of pre-measurement and control software system and ground measurement and development control software system in the test process is improved, and the stability of the software in the test and launch test of the carrier rocket is ensured, which provides ideas for the reliability research of the ground measurement and development and control system software of the carrier rocket in the future.
