Abstract

A motor closed-loop monitoring control system includes a controller, a control board, a driver, a motor, a reducer and a sensor. The controller is electrically connected with the control board, and the controller monitors a current signal voltage fed back by the control board in real time and outputs a level signal for driving the control board. The control board is electrically connected with thedriver, and the control board outputs an isolated level signal to control the driver. The driver is electrically connected with the motor, and the driver outputs a motor driving sequence to drive themotor. The motor is mechanically connected with the reducer. The reducer is mechanically connected with the sensor, and the sensor tests and records angle information output by the reducer. The sensor is electrically connected with the control board to output the angle value of the motor. The control board is electrically connected with the controller, and the control board outputs angle information to the controller through communication. The whole system adopts closed-loop control, so as to realize the lifting control and measurement of an oil pumping pipe of an oil-water pumping and draining device and ensure the smooth progress of the oil pumping work.

Description

technical field [0001] The invention belongs to the technical field of oilfield equipment, and relates to a motor control system of pumping and drainage equipment, in particular to a motor closed-loop monitoring control system and a control method. Background technique [0002] At present, the drainage and pumping of liquid storage tanks in oilfield gas gathering stations is still in the stage of manual operation. [0003] When pumping water, the monitoring personnel will open the valve remotely, and the personnel outside the station will lower the pipeline of the suction port to the bottom of the liquid storage tank based on experience. When pulling oil, the work area arranges guardians to go to the station, and the pulling personnel insert the hose on the car into the tank. According to experience, the hose head is parked in the oil layer. When cloudy, pull out the hose and stop working. [0004] However, the above-mentioned traditional methods all require on-site superv...
