Problems solved by technology

At present, the frequency conversion speed regulation of belt conveyors is generally controlled by humans, or some sensors with low reliability, susceptible to interference, and high cost are used for monitoring, but limited by the actual situation, many belt conveyors with frequency converters have not realized intelligence. Speed ​​regulation only plays the role of a soft starter, and it does not reflect the difference and superiority of the inverter drive and other drive methods.
Normally, the belt conveyor keeps running at high speed, without supporting speed regulation according to the excavation conditions of the coal mining machine, the wear on the belt is serious, which not only causes waste of electric energy, but also accelerates the wear speed of the belt

Abstract

The invention discloses a belt conveyor and coal mining machine automatic speed regulation method based on coal quantity detection. The automatic speed regulation method comprises the following steps that the coal flow of a belt conveyor is detected; state data information of the belt conveyor is collected; state data information of a coal mining machine is collected; an algorithm model is established according to the coal flow detection of the belt conveyor, the state data information collection of the belt conveyor and the state data information collection of the coal mining machine; and according to the algorithm model, a coal flow control threshold value of the belt conveyor and a speed control threshold value of the coal mining machine are obtained, and therefore the speed of the belt conveyor and the speed of the coal mining machine are controlled. According to the belt conveyor and coal mining machine automatic speed regulation method based on coal quantity detection, belt and coal mining machine optimal control can be achieved according to the coal quantity detection and the state data information of the coal mining machine.

Description

technical field [0001] The invention relates to the field of coal mining automation, in particular to an automatic speed regulation method for a belt and a shearer based on coal quantity detection. Background technique [0002] At present, belt conveyors driven by frequency conversion motors are more and more widely used in coal mines, and the degree of automatic mining of coal shearers has also increased. At present, the frequency conversion speed regulation of belt conveyors is generally controlled by humans, or some sensors with low reliability, susceptible to interference, and high cost are used for monitoring, but limited by the actual situation, many belt conveyors with frequency converters have not realized intelligence. Speed ​​regulation only plays the role of a soft starter, and it does not reflect the difference and superiority between the inverter drive and other drive methods. Normally, the belt conveyor keeps running at a high speed, without supporting speed r...
