中国航天科技集团公司电子技术研究院771所是我国微电子和计算机领域的核心研制生产单位,其与神舟九号飞行任务配套的产品均为飞行和返回的重要设备,与航天员的生命安全和完成在轨工作息息相关,对神舟九号载人交会对接任务起着至关重要的作用。数管分系统中央单元是数管分系统返回舱的主控计算机,在飞船飞行的过程中,完成对整个数管分系统设备的控制、管理以及对挂在总线上的其他分系统设备的控制,可靠性要求很高。中央单元完成的功能是以程控、校时、总线通讯、数据管理和故障处理为主,同时要求支持遥控、遥测、逃逸、应急返回和地面综合测试。
China Aerospace Science and Technology Corporation Institute of Electronic Technology 771 is the core of China’s micro-electronics and computer development and production units, and its Shenzhou-9 flight mission matching products are important equipment for flight and return, and astronauts life safety and Completion of the orbital work is closely related to the Shenzhou 9 manned rendezvous and docking mission plays a vital role. The central unit of the number pipe system is the main control computer of the return system of the number pipe system. During the flight of the spacecraft, the control and management of the entire number of pipe system equipment and the control of other subsystems and equipment hanging on the bus are completed , High reliability requirements. Central unit to complete the functions of the program control, school time, bus communication, data management and troubleshooting mainly at the same time require support for remote control, telemetry, escape, emergency return and ground integrated test.
