Description

technical field [0001] The present application relates to the technical field of material flow detection, in particular to a belt material flow detection method and device, and a belt material flow detection system. Background technique [0002] In recent years, with the rapid development of the national economy, the demand for energy is increasing day by day, and the high-efficiency transportation of coal is also very important. It has successively invested in the construction of Huanghua Port, Tianjin Port, Caofeidian Port, Jingtang Port and Qinhuangdao Port. A batch of special coal wharves ensure the supply of energy needed for the country's economic development. Coal in the port is generally transported by belt conveyors. The coal is dumped from the dumper to the belt conveyor, transported to the storage yard by stackers and stacker-reclaimers, and then loaded by shiploaders. Therefore, the belt conveyor is the main coal transportation equipment in the port. In the ent...

Problems solved by technology

[0003] The traditional belt material flow detection technology is usually realized through contact-type tilt switches, pull-rope switches and other equipment. However, the inventor found that the above-mentioned methods usually have the following problems during the implementation process: contact-type tilt switches, pull-rope switches etc. are in direct contact with the material flow, and the belt conveyor runs very fast. After the contact switch equipment is used for a long time, it may cause loosening and wear of the contact switch, resulting in false detection or missed detection. , that is, no lean stream is detected
