Design and implementation of constant pressure water supply monitoring system based on STM32

摘要

In order to reduce the design difficulty and cost of constant pressure water supply control system controlled by PLC, STM32 was chosen in this system as processor and intelligent constant pressure water supply monitoring system was designed based on Modbus-RTU communication protocol to realize the real-time data acquisition, display, fault alarm and water pressure alarm function. In addition, accuracy will be improved and energy consumption will be reduced when the pump outlet pressure of the system is operating. The software design of computer system using fuzzy PID algorithm. The system can control the speed of water pump according to dynamic output frequency signal of the data acquisition to achieve a good control about constant pressure of water supply and pump frequency meeting the design requirements of the system. Finally, getting the system simulation results and test results and the interpretation and analysis about them were given. Experimental results show that the system is economical and practical. It has strong anti-disturbance ability and can be widely used in industrial control field.
