Working face equipment positioning system

The invention discloses a working face equipment positioning system suitable for accurately sensing movable equipment and personnel positions in real time in the coal mining process. The system is composed of hydraulic supports, a coal mining machine, anchor points, chipless labels, a scraper conveyor, a positioning server and the like. Ultra-wideband communication is adopted between the anchor points and the chipless labels, the distances between the anchor points and the labels are measured by means of the high-time-domain resolution property of ultra-wideband, and the physical characteristics such as the speeds, movement directions and accelerations of measured objects are measured by inertia units on the chipless labels. The anchor points collect the distances between the anchor points and the chipless labels arranged under top beams of the hydraulic supports as well as movement parameters, and transmit the distances and the movement parameters to the positioning server, the movement states such as the ac
