Design of Constant Temperature Monitoring System Based on MCGS

In the current enterprise material management, constant temperature preservation is an important basic preservation method, which directly affects the quality and safety of the stored items, and is crucial for the preservation of items requiring strict temperature control. Based on this, this paper designs a constant temperature monitoring system, which can timely and automatically adjust the operation status of the cooling and heating fan according to the change of the entrance and exit temperature. The design mainly includes a system framework diagram, main circuit diagram, control circuit diagram, program flowchart, PLC ladder diagram, and so on. On this basis, the monitoring system design is based on MCGS configuration software, and the main contents of the design include the main monitoring interface, real-time reports, real-time curves, historical curves, and so on. Users can monitor the real-time working status of each system component intuitively on the configuration interface. This design adopts MCGS configuration software to configure the PLC-based thermostatic control system, which not only realizes the intuitive monitoring of the control process, but also achieves the instantaneous collection and processing of the operation data, and has good reference value for practical application.
