Abstract:In recent years, with the further development of automation technology, the related programming technology represented by PLC (Programmable Logic Controller, programmable logic controller,) has been more widely used. This paper mainly analyzes the overall design idea of PLC pig breeding environment control system, and studies the design of PLC monitoring system in the breeding environment. After research, it was found that the PLC center control module is the core of the whole monitoring system, and the hardware assembly should be carried out according to the setting requirements of the industrial control system. Based on the above conditions and requirements, some adjustment suggestions are put forward for the application of PLC pig breeding environmental control system in sewage treatment and temperature regulation, in order to realize the stability and reliability of the environmental control system for pig breeding.
