    摘要:

    前置測控軟件是運載火箭地面測發(fā)控系統中的重要組成部分,主要負責試驗和發(fā)射中運載火箭的地面部分數據的采集和顯示以及控制,具有實(shí)時(shí)性強、可靠性高、數據量大和接口關(guān)系復雜等特性;針對目前航天發(fā)射呈現任務(wù)高密度常態(tài)化,試驗次數增多,對前置測控軟件的可靠性需求提高的問(wèn)題,研究了基于心跳信號的熱備冗余系統,通過(guò)設置主備兩份軟件以及互相之間心跳信號通信的方式,在主份軟件故障情況下,可實(shí)現軟件冗余系統自主切換,提升了在試驗過(guò)程中前置測控軟件和地面測發(fā)控軟件系統的整體可靠性,保證了軟件在運載火箭在測試和發(fā)射試驗中的穩定性,為未來(lái)運載火箭地面測發(fā)控系統軟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.
