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

    整流罩空調(diào)系統(tǒng)任務(wù)就是要保證達(dá)到航天器、運(yùn)載火箭測(cè)控系統(tǒng)等各種設(shè)備、儀器儀表在發(fā)射準(zhǔn)備及發(fā)射時(shí)所要求的空氣參數(shù),否則衛(wèi)星無法正常工作,使耗資巨大的衛(wèi)星只能在太空中毫無意義地空轉(zhuǎn)[1-2]。

    傳統(tǒng)整流罩空調(diào)控制系統(tǒng)核心設(shè)備可編程控制器(PLC)多以Siemens[3]、Schneider[4]、Rockwell[5]、GE[6]、Mitsubishi[7-8]、Omron[9]等國(guó)外品牌占領(lǐng),直接結(jié)果就是核心技術(shù)無法實(shí)現(xiàn)自主安全,存在較大安全隱患。

    控制策略方面,現(xiàn)場(chǎng)的冗余方案是三臺(tái)西門子機(jī)組互冗余,單臺(tái)機(jī)組核心模塊未冗余,功耗高、成本高、設(shè)備故障率高、可靠性低、機(jī)組復(fù)雜。

    針對(duì)上述問題,結(jié)合提高可靠性的方案核心機(jī)組被控設(shè)備冗余[10]、核心控制設(shè)備CPU軟冗余[11-13],本文提出一種基于國(guó)產(chǎn)PLC的冗余整流罩空調(diào)自動(dòng)控制系統(tǒng)。國(guó)產(chǎn)PLC采用基于國(guó)產(chǎn)軟硬件平臺(tái)、具有自主知識(shí)產(chǎn)權(quán)的超御PLC產(chǎn)品??刂撇呗苑矫?,機(jī)組系統(tǒng)互為冗余,單臺(tái)機(jī)組CPU、核心被控設(shè)備冗余。
