Abstract

The invention discloses a method for prolonging life of an intelligent control sensor of a motor. A water pump, a pressure sensor, a single-chip microcomputer, a drive element and a pump motor are provided. The pressure sensor is used for measuring interior real-time water pressure of the water pump. The single-chip microcomputer is used for continuously transmitting a detection signal to the pressure sensor. The pressure sensor returns a feedback signal to the single-chip microcomputer. After determination and calculation, a pump head motor control signal suitable for a current motor type is output; or the single-chip microcomputer directly outputs a set program signal; on and off of the drive element of high power is controlled, and filtering and anti-interference of chaotic control electrical signals is achieved; the single-chip microcomputer outputs a control signal of proper duty ratio according to the acquired feedback signal and the motor type; accordingly, operating frequency of the pressure sensor and that of the pump motor are decreased, the service life of the pressure sensor and that of the pump motor are prolonged, and the problem that excessively high start frequency of the pressure sensor and that of the pump motor, both running at a critical point, cause shortened life of the pressure sensor and shortened life of the pump motor is solved.

Description

technical field [0001] The invention relates to a method for prolonging the service life of an intelligent motor control sensor, in particular to a method for prolonging the service life of all motors, pressure sensors and drivers. Background technique [0002] At present, when the motor is working under the intelligent control mechanism, the load current of the motor flows directly from the control switch, or is completed through the conversion of the relay. However, the working principle of the control switch and the relay is contact conduction. If the load current is too large, the life of the control switch, the relay and the pump motor will be greatly reduced (row: the water pump motor merchants on the market have a warranty of 3 months or 6 months. ), which cannot meet the national quality and life standards, and the price of the motor is expensive, the service life of the motor is short, it needs to be replaced frequently, the maintenance cost increases, and the produ...
