Design of Networked Control System for Submersible Pump

The resources in the deep water area are very rich, thus the submersible pump has been widely used in the industrial production to extract these resources. However, when the submersible pump is running in the deep water area, there are some commom problems such as how to control the speed of the motor and how to get the operating status of the pump. Aiming at these problems, a networked control system for submersible pump based on RS-485 bus is put forward in this paper. The hardware platform is based on STM32 series microcontrollers and the sensorless control algorithm is applied so as to decrease the volume of the pump. Experimental results demonstrate the validity and practicability of this system. Meanwhile the system will have good application value in the future.
