Method for monitoring efficient and safe operation of coal mining face ribbon conveyer

Abstract

The present invention discloses a method for monitoring efficient and safe operation of a coal mining face ribbon conveyer. The method comprises: step 1, arranging hardware equipment used for monitoring; step 2, performing data collection and transmission; and step 3, performing data processing and efficient safe and operation control of the ribbon conveyer. The method in the present invention method is simple in steps. Feature point data of a coal flow outer contour is detected by using a laser radar, a real-time belt speed of the conveyor belt is detected by using a rotary encoder, and a coal flow can be efficiently and accurately detected through data analysis processing and calculation on data by a computer. A visual sensor is used for efficiently and accurately detecting a coal contour on the conveyor belt, so that accurate and automatic recognition of large-sized coal on a mining face is implemented. Coal flow detection efficiency is high, and precision is high. A large-sized coal recognition method is simple and reliable, has a small error, is of great significance to efficient and safe operation of an underground coal mine ribbon conveyer, and is easy to popularize and use.

Description

technical field [0001] The invention belongs to the technical field of coal mine production process monitoring, and in particular relates to a method for monitoring the efficient and safe operation of a belt conveyor on a coal mine working face. Background technique [0002] Coal is one of the main energy sources in our country, and its position will not change for a long time. Although with the continuous reduction of coal storage in my country and even the whole world, various countries are paying more and more attention to the development and utilization of primary energy, but my country's current underground coal gasification or other technologies are still relatively weak, and some industries still rely on coal. Therefore, for some time to come, coal mining will continue. [0003] At present, in the fully mechanized mining face or tunneling face of coal mines, in the process of transferring coal to the belt main transport system through scraper conveyors and transfer m...

Problems solved by technology

[0003] At present, in the fully mechanized mining face or tunneling face of coal mines, in the process of transferring coal to the belt main transport system through scraper conveyors and transfer machines, the degree of automation is low for the detection of large lumps of coal, and the reloader is still used. Stare at the side to see if there is a large piece of coal; most of the detection of coal flow at present often ignores the gap between the belt and the idler, and considers that the belt is completely in contact with the idler, that is, the belt is used as the belt in the calculation of the coal flow cross-sectional area. Straight line processing, but the actual belt is arc-shaped and cannot be in fu
