Description

technical field [0001] The invention belongs to the technical field of underground personnel positioning systems, in particular to an underground personnel positioning system based on power carrier technology. Background technique [0002] With the continuous deepening of my country's economic system reform and the accelerating modernization process, the country has paid more and more attention to coal mine safety, and the supervision has been continuously strengthened. Large and medium-sized coal mines and many small township coal mines have been equipped with a large number of coal mine safety monitoring systems, which have effectively curbed major gas explosions. Accidents happen. However, there is a lack of monitoring of the location information of underground personnel. At present, it is still difficult to manage the personnel entering the well. It is difficult for the personnel on the well to accurately grasp the distribution and operation of the underground personnel i...
