Intelligent speed regulation method for belt conveyor based on material monitoring

Abstract

The invention discloses an intelligent speed regulation method for a belt conveyor based on material monitoring. The method comprises the steps that material loads at different positions of the belt conveyor and corresponding driving motor rotating speeds are obtained through manual teaching speed regulation and serve as training data to train an initial neural network, a neural network system with cognitive ability is obtained, and after training is completed, an intelligent speed regulation system is started; according to material information data collected by a material monitoring device in the actual operation process of the belt conveyor, material load capacity data of different positions of the belt conveyor are obtained through calculation of a core processor and are conveyed to a neural network with cognitive ability; the neural network system carries out prediction to obtain the current best rotating speed of a driving motor of the belt conveyor, and a belt conveyor control system carries out variable-frequency speed regulation on the driving motor. According to the method, the energy consumption of the belt conveyor motor can be effectively reduced, the accidents of coal accumulation can be reduced, the speed regulation range and precision are large, and the purposes of energy conservation, consumption reduction and safe production are achieved.

Description

technical field [0001] The invention relates to a belt conveyor speed regulation method, in particular to an intelligent belt conveyor speed regulation method based on material monitoring, and belongs to the technical field of belt conveyor speed regulation. Background technique [0002] With the continuous development of comprehensive mechanized coal mining technology, scholars at home and abroad have successively put forward the idea of ​​"unmanned" or "less-manned" coal mining face. [0003] Because the belt conveyor has the best transportation effect on bulk materials, it is widely used in coal mines, docks and other occasions. It is precisely because the belt conveyor is used in a wide range of occasions that it also puts forward more requirements; as the main transportation of mines The energy consumption of equipment and belt conveyors has a significant effect on the transportation costs of enterprises such as coal mines and mines. The following problems will exist in...

[0003] Because the belt conveyor has the best transportation effect on bulk materials, it is widely used in coal mines, docks and other occasions. It is precisely because the belt conveyor is used in a wide range of occasions that it also puts forward more requirements; as the main transportation of mines The energy consumption of equipment and belt conveyors has a significant effect on the transportation costs of enterprises such as coal mines and mines. The following problems will exist in the operation mode of power frequency and constant speed: the friction coefficient between the machinery and the conveyor belt is large. If the conveyor is empty or light Loading will cause waste of electric energy, and it is easy to cause coal pile accidents if it keeps moving at a constant speed

[0005] A Chinese invention patent published on February 16, 2018 has a publication number of CN107702755A "belt conveyor flow detection device and detection method",
