载人航天逃逸安控系统优化设计

Optimization Design of Escape and Safety Control System in Manned Space Project

为进一步提高载人航天飞行任务中逃逸安控系统指令发送的安全性、可靠性,提出优化设计方法。将火箭接收逃逸指令的通道和接收安控指令的通道进行一体化体制换代,升级为多音组合编码调频(主字母)体制,对箭上、地面逃逸安控系统进行一体化设计。同时,继续保留USB设备向飞船发送逃逸指令的通道。通过对比,优化设计后的逃逸安控系统在指令安全保密性、设备覆盖性、系统可靠性等方面得到了全面提升。

To improve the safety and reliability of escape and safety control system instruction transmission in manned spaceflight missions,an optimization design method was proposed.The channel for the rocket to receive escape instructions and the channel for receiving security control instructions were replaced with an integrated system,the upgrade to the high alphabet system was performed,and the integrated design of the escape and security control system on the rocket and on the ground was conducted.The channel for the USB device to send escape instructions to the spacecraft was retained.The comparison results showed that the performance of the optimized escape and safety control system was comprehensively improved in terms of command security,equipment coverage and system reliability.
