Research on Hot Spare Redundancy of pre-measurement and control software in measurement and production control system

摘要:

前置测控软件是运载火箭地面测发控系统中的重要组成部分,主要负责试验和发射中运载火箭的地面部分数据的采集和显示以及控制,具有实时性强、可靠性高、数据量大和接口关系复杂等特性；针对目前航天发射呈现任务高密度常态化,试验次数增多,对前置测控软件的可靠性需求提高的问题,研究了基于心跳信号的热备冗余系统,通过设置主备两份软件以及互相之间心跳信号通信的方式,在主份软件故障情况下,可实现软件冗余系统自主切换,提升了在试验过程中前置测控软件和地面测发控软件系统的整体可靠性,保证了软件在运载火箭在测试和发射试验中的稳定性,为未来运载火箭地面测发控系统软件可靠性研究提供了思路；

Abstract:

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.
