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.
