Abstract:Aiming at the requirements of the design parameters temperature, humidity and air volume of the fairing air conditioner in a launch site, the implementation plan of the traditional fairing air conditioning system was investigated. In this paper, from the aspects of information security and reliability, a redundant automatic control system for air conditioning with fairing based on domestic PLC was proposed. In this regard, the article introduces the functions of domestic super Yu PLC components, redundant unit system scheme, and builds the system architecture and control scheme from the hardware and software aspects. Through on-site experimental debugging, the feasibility and stability of the fairing air conditioning control system are verified, and it has obvious advantages such as safety and reliability. It solves the problem of zero application of domestic PLC in the fairing air conditioning system and is a high reliability fairing air conditioning system design plan.
Key words :fairing;air-conditioning control system;PLC;independent safety

整流罩空调系统任务就是要保证达到航天器、运载火箭测控系统等各种设备、仪器仪表在发射准备及发射时所要求的空气参数,否则卫星无法正常工作,使耗资巨大的卫星只能在太空中毫无意义地空转[1-2]。
传统整流罩空调控制系统核心设备可编程控制器(PLC)多以Siemens[3]、Schneider[4]、Rockwell[5]、GE[6]、Mitsubishi[7-8]、Omron[9]等国外品牌占领,直接结果就是核心技术无法实现自主安全,存在较大安全隐患。
控制策略方面,现场的冗余方案是三台西门子机组互冗余,单台机组核心模块未冗余,功耗高、成本高、设备故障率高、可靠性低、机组复杂。
针对上述问题,结合提高可靠性的方案核心机组被控设备冗余[10]、核心控制设备CPU软冗余[11-13],本文提出一种基于国产PLC的冗余整流罩空调自动控制系统。国产PLC采用基于国产软硬件平台、具有自主知识产权的超御PLC产品。控制策略方面,机组系统互为冗余,单台机组CPU、核心被控设备冗余。
