为完成“人-船-服”出舱活动联合试验任务,需要对原有KM6水平舱进行适应性的功能改造。为了确保宇航员的生命安全,必须提高整个控制系统的可靠性。测控系统在总体结构上采用SIEMENS PCS7冗余集散控制系统的方式,对所有关键测控环节(包括控制计算机、CPU、电源、网络、I/O模块等)都进行了冗余备份,并对重要操作中关键参数互联、互锁,杜绝误操作,确保有完善的系统监控和故障报警功能。改造后通过多次调试和多种试验模式演练,各分系统和总控系统测控功能均达到设计指标要求。
In order to accomplish the joint testing task of “man-ship-service” exiting activities, the adaptive functional transformation of the original KM6 horizontal cabin needs to be carried out. In order to ensure the safety of astronauts, the reliability of the entire control system must be increased. Measurement and control system in the overall structure of SIEMENS PCS7 redundancy distributed control system approach to all key measurement and control links (including the control computer, CPU, power, network, I / O modules, etc.) are redundant backup, and important operations In the key parameters of interconnection, interlocking, put an end to misuse, to ensure that there is a sound system monitoring and fault alarm. After the transformation through multiple commissioning and testing of a variety of test mode exercises, the subsystems and the overall control system measurement and control functions have reached the design requirements.
