Abstract :
In order to supply cold water for engine laboratory PLC, configuration software, HMI, and inverter are adopted to construct an automatic control system in this paper. The control system is a distributed control system, which has higher dependability and maintainability. The reading and writing network instructions are utilized to solve the communication among multi-master problem. The remote monitoring software is developed with configuration software. By measuring temperature and pressure of entrance and exit pipes, refrigeration equipments and water pumps are adjusted real-time to guarantee to supply stable temperature and pressure cold water. Therefore the quality of water is improved and power is saved. Practice proves that the system designed meets user´s requirement. The system has a good reliability and high degree of automation.
