载人航天工程地面逃逸安控系统可靠性技术

Reliability Technology of the Ground Escape and Safety Control System in the Manned Space Project

在载人航天任务中,保障航天员的生命安全是地面逃逸安控系统的首要任务,该系统具有高可靠性、高安全性.因此,对其可靠性进行研究十分必要.主要研究了逃逸安控系统可靠性技术,包括数据接收与处理、逃逸安控软件、指挥模式与指令发送等几个关键环节的可靠性,提出了提高系统可靠性的方法和措施,完善了地面逃逸安控系统可靠性设计,为圆满完成后续载人飞行任务打下良好基础.

In the manned space task, ensuring the safety of spacemen is the chief task of the ground escape and safety control system. The system are of high security and high reliability. So, studying the reliability of the system is very necessary. The objects of studying the reliability are mainly the key parts, such as the receiving and processing of data, the software of the ground escape and safety control system, the commanding mode and the instructions sending, and etc. The studying puts forward the methods and measures of improving the system reliability, perfects the reliability design and lies a solid foundation for completing the future task successfully.
