Abstract
Aiming at the problems of frequent transfer, rough transfer mode and large transfer range of high-voltage cable in open-pit coal mine, which lead to low cable allocation efficiency, untimely maintenance and repair, and even cable loss and theft, a low-power high-voltage cable positioning method in open-pit coal mine based on GPS is proposed. In order to reduce the battery loss, the cable positioning terminal adds the motion state detection function. When the cable is moved in a large range and scale, the positioning terminal wakes up and increases the transmission frequency, and continuously sends the GPS positioning information to the control center through the LoRa network; When the cable is stationary or the movement is not obvious, the positioning terminal will sleep for a long time and send positioning information to the control center with a long transmission cycle. The electronic fence function is adopted to realize the anti loss and anti theft function of high-voltage cable. If the high voltage cable appears outside the electronic fence, the system will alert the administrator. The control center analyzes and processes the high-voltage cable position information to realize the purpose of monitoring and management. The practical application results show that the use of this method not only improves the allocation, repair and maintenance efficiency of high-voltage cables in open-pit coal mines, but also effectively reduces the loss and theft of cables.
