RFID electric locomotive unmanned driving system realizes underground application

Recently, the unmanned system of the underground 1350m rail transport horizontal electric locomotive developed by Beijing Beikuang Intelligent Technology Co., Ltd., a subsidiary of Mining and Metallurgical Group, has been used underground in Jinchuan No.3 Mining Area. The operator of the electric locomotive completes the fully automatic driverless function by inputting the ore-distribution command in the central control room. The entire process does not require driver intervention, effectively improving the working environment of underground personnel, reducing the labor intensity of employees, improving the efficiency of rail transportation, and improving The level of mine safety management and control achieves the goal of intelligent and unmanned underground mines.

The unmanned driving system of the electric locomotive adopts the research and development achievements of the Mining Technology of Underground Metal Mine project of the Mining and Metallurgy Group. It has many advantages in running in the underground environment. First, it realizes accurate positioning underground. The electric locomotive uses a combination of RFID passive beacon + encoder + non-contact induction switch triple positioning system to achieve precise displacement and positioning of the electric locomotive; the second is the use of wired + wireless + leaky communication method to effectively make up for the underground special environment The communication blind spot ensures the continuity, stability and safety of the communication during the system operation, and provides a solid guarantee for the reliable operation of the unmanned driving system; the third is the use of special video monitoring at the rear of the train to the on-site working conditions of the last car At a glance, it provides a reliable guarantee for the safe operation of unmanned driving; the fourth is the integration of the six major system personnel positioning systems, the well sounding system and the unmanned driving system to complement each other; the fifth is to achieve the first The key-type unmanned driving function truly realizes the "unmanned driving" of underground electric locomotives.
