Abstract: At present, some mines have laid out the 4G wireless communication network based on TD-LTE. Aiming at the shortcomings of the existing explosion-proof trackless vehicle monitoring instrument, the real-time monitoring system of underground explosion-proof vehicle running condition of TD-LTE technology was developed. The article describes in detail the advantages of applying TD-LTE technology wireless networks in mining vehicles and the principle structure and test of the system are introduced. The application results show that the system can stably transmit the data, video and voice of the underground vehicle, which can strengthen the trackless rubber tire operation of the supervision and scheduling to protect the auxiliary transport safety and improve transport efficiency.
