Design of Coal Mine Belt Motor Speed Monitoring System Based on DSP

In recent years, with the further advancement of resource integration and merger and reorganization of small coal mines in China, the pace of mechanized transformation of coal mines has been accelerated, and the level of coal mine safety production guarantee has been improved, which has greatly promoted the improvement of coal mine safety production situation. However, the progress of coal mine merger, reorganization and integration of technological transformation is uneven among regions, and some coal mines with integrated technological transformation violate regulations or evade closure in the name of integrated technological transformation. There are a lot of hidden dangers in the process of coal mine merger, reorganization, integration and technical transformation. Flammable gases such as gas easily explode when they meet sparks, and accidents in production safety often occur. Belt conveyor for coal mine has the characteristics of large transportation volume, complex working environment, strong bearing capacity and long transportation distance. It is widely used in Shanxi, Inner Mongolia, Xinjiang and other major coal producing areas in China. Belt conveyor for coal mine can be used not only in coal production and processing, but also in other mineral production and processing. Coal mine belt motor is the power source of coal mine belt conveyor, its safety is directly related to the safety of coal mine conveying system. It is of great significance to carry out the research on the detection technology of coal mine belt motor running speed for improving the reliability of coal mine belt transportation, eliminating potential safety hazards and reducing production accidents.
