An intelligent control system and control method for an emulsion pumping station

Abstract

The invention provides an intelligent control system and a control method of an emulsion pump station. The intelligent control system of the emulsion pump station comprises an emulsion tank, a first high-power emulsion pump, a second small-power emulsion pump, a liquid quantity sensor of the emulsion pump station, a controller, a sensor for starting and shutting down of acoal mining machine, a liquid inlet quantity sensor of a working face, a liquid return quantity sensor of the working face, a liquid return pipeline of the working face, a liquid inlet pipeline of the working face, a sensor signal line, control signal lines of the emulsion pumps, a support moving device, a reversed loader moving device and an advanced processing device. According to the intelligent control system and the control method of the emulsion pump station, the starting and the shutting down of a system device and change values of flow quantity are collected as a signal source, invalid operation of the emulsion pumps is reduced to the maximum extent under the situation that a liquid using condition of the working face is ensured, a lot of electricity fees can be saved, frequent starting is avoided so that the device is prevented from being burnt out.

Description

technical field [0001] The invention belongs to the field of automatic control of electromechanical equipment in coal mines, and in particular relates to an intelligent control system and a control method of an emulsion pumping station. Background technique [0002] In the prior art, the system pressure change is used as a signal to control the work of the emulsion pump station equipment, and the system pressure change is collected as a control signal. When the system pressure drops to the start-up set value, the start-up is started; stop when the value is reached. It cannot judge whether the system is leaking, what process uses liquid, whether the amount of liquid is large or small, and it cannot make instructions to continuously turn on high-power emulsion pumps or temporarily turn on low-power emulsion pumps. It can only do pressure Start when the pressure is low, and stop when the pressure is high, causing the emulsion pump station equipment to start frequently and burn...
