载人火箭的遥测系统

Telemetry System of Manned Launch Vehicle

火箭遥测系统的作用是对火箭飞行过程中所有的动态参数进行测量,并以无线发射形式将数据实时发送回地面。载人运载火箭的遥测系统不仅承担了火箭飞行过程中所有动态参数的测量,而且是载人火箭在故障判决工作中的重要组成部分,承担着火箭Ⅰ、Ⅱ类参数的测量和传输,为提高系统可靠性采取了大量行之有效的办法,在系统的关键部分和薄弱环节采取多种形式的冗余、并联等可靠性设计,系统及参数测量的可靠性达到同行业中较高水平。文章对遥测系统的研制任务、系统组成、关键技术和高可靠性等方面进行全面介绍。

The function of launch vehicle telemetry system is to measure all the dynamic parameters during flight and to implement data real-time wireless sending to ground station. Not only the manned launcher telemetry system is responsible for all dynamic parameter measurements, but also it takes charge of the fault judgment of launcher. Telemetry system takes charge of the measurement and transmission of class Ⅰ and class Ⅱ parameters. It adopts many redundancy andparallel designs for reliability improvement of system at pivotal and unsubstantial parts. The measurement reliability of telemetry system achieves a better level compared with others. This article is an all-around introduction to telemetry system about its design mission, system structure, key technology and high reliability.
