Remote Control And Automation Technology For Electric Locomotive

According to reports, the electric locomotive transportation system consists of intelligent unmanned variable frequency electric locomotive, roadway mobile wireless communication system, electric locomotive automatic dispatching, protection and monitoring system, and electric locomotive transportation power supply management and control system.

The underground mining locomotive traction train unit realizes remote remote loading and unloading, automatic operation and unloading during operation. The operating status is displayed in the dispatching room in real time through wireless communication, and can be remotely controlled in real time when necessary, which is very convenient. This technology can be adapted to the needs of simultaneous transportation of multiple trains of locomotives. After using this technology, the transportation system operator will be reduced from 40 to 8 people, which greatly improves the transportation efficiency and reduces the production cost. In the unmanned state, after the locomotive is started according to the instructions of the centralized control room, it can continue to run repeatedly in accordance with a preset program. If a fault occurs during operation, the locomotive can self-diagnose, and the diagnostic information will be fed back to the control room display screen, prompting the staff to perform necessary manual processing.

As everyone knows, underground mining is a high-risk job. Due to different mining methods and the nature of the mining ore, the hazards of mining operations are very different. Among them, the death rate of coal mining industry is much higher than that of other mining industry, and the injury rate of coal mining industry is also significantly higher than that of other mining industry. In the same mining industry, the accident rate of underground mining is higher than that of surface mining, and the death and non-fatal accident rates of underground mining are generally 1 to 2 times higher than those of surface or surface mining. At present, most of the transportation equipment used in mines in China requires manual driving, and the working conditions, safety guarantees and transportation efficiency are greatly restricted. The unmanned electric locomotive can not only greatly increase the degree of automation of ore transportation in the mine, but also give full play to the transportation capacity, and also provide a reliable guarantee for preventing injuries and deaths during the transportation of the mine.

In mines, electric locomotive is an important transportation equipment in metal mines. A lot of ore, equipment, materials and personnel depend on electric locomotive for transportation. The locomotive's running route is fixed and the running route is closed. The running process is easy to achieve program standardization, and the unmanned driving of the locomotive has an objective basis. Unmanned electric locomotive can achieve maximum safety transportation, avoiding injuries to personnel due to collisions, derailments, rear-end collisions, etc. Unmanned electric locomotive can reduce workers in harsh environments and improve work efficiency. The control system of the unmanned electric locomotive realizes three major functions: automatic driving, tracking and positioning, and data exchange with a higher-level monitoring system.

It is foreseeable that the development and application of remote control and automation technology for underground mining locomotive will be the development trend of the electric locomotive industry. The underground mine unmanned electric locomotive transportation system will definitely drive the prosperity of the domestic electric locomotive industry and help domestic electric locomotive companies Seize the share of China's electric locomotive trading market!
