Research on the Automatic Control System of Flow Temperature and Humidity Based on PLC Control
Aiming at the traditional manual operation of a performance analysis test bench,an automation transformation was carried out,and the overall idea of the transformation was explained.The system structure diagram of the hardware structure and software design process were provided.Automatic adjustment of test parameters and automatic collection and storage of test data based on PLC control and host communication.Introduce cloud servers to transmit real-time data to the cloud,enabling remote control of the test bench and remote data reading and storage.The results showed that the modified performance analysis test bench achieved fully automatic adjustment of temperature and humidity parameters in automatic mode until the test reached a stable state.In manual mode,the test parameters at both local and remote ends can be adjusted,greatly improving the stability of the system.In two modes,the system can greatly reduce labor intensity,reduce workload,shorten working hours,and improve work efficiency.
