The Design of Recirculating Aquaculture Temperature Control System Based on PLC
In order to improve the aquaculture monitoring system in China, this paper designs a system adopting the SIMATIC S7-200 CPU226 and PID control algorithm to make real-time monitoring and controlling for the water level and temperature of closed circulating aquaculture system, thus it can realize constant control of water level and temperature in the culture pond. The overall control scheme and principle of the system are introduced in detail, followed by the structure design of the system software and hardware. The designed system can efficiently achieve system logic control, safety control, fault display and fault treatment.
