Problems solved by technology

At present, the application equipment based on this principle is insufficient. The detected voltage and current signals are greatly affected by the discrete factors of the acquisition environment, and when the water pump is blocked or other unexpected failures, it is easy to lose control, resulting in motor overheating and damage.

Abstract

The invention discloses an intelligent control device for pump electromotor that includes input node and output node. Pump electromotor is connected to output node. Marker is set on the rotating shaft of the pump electromotor. Sensor module is set corresponding to the marker. The sensor module sends signal to the marker place and receives reflected signal. The output signal generated by the sensor module is output to programmable microprocessor. The control signal generated by the programmable microprocessor would be send to switch circuit to control pump electromotor to rotate.

Description

technical field [0001] The invention relates to an intelligent water pump motor control device. Background technique [0002] In general, water pumps can be controlled in different ways. The easiest way is manual control, the operator can control the switch according to the amount of liquid being pumped. However, manual control has some limitations. For example, if no one is operating, the water pump motor is either normally open or normally closed. Normally open will cause the motor to heat up and burn out; normally closed will cause the liquid level to exceed the limit. [0003] Therefore, manufacturers have developed some automatic controllers for water pumps. A switch is usually controlled by a liquid level detection device such as a float or a sensor, so that when it is closed, the water pump motor is turned on, and when it is opened, the water pump motor is stopped. Although this type of automatic device is more advanced than manual control, there are still many pr...
