[0002] The heavy haul railway network is mostly typical mountainous railway, with great risk of natural disasters and geological disasters. With the large-scale operation of long and large marshalling heavy haul locomotives, the risk and pressure of locomotive operation safety have also increased dramatically, which restricts the further development of heavy haul transportation. In recent years, in order to ensure the safety of heavy haul railway locomotive operation, video monitoring systems have been constructed on some lines of heavy haul railway. The video collection points mainly cover tunnels, operation areas, slopes, level crossings, power supply facilities, train rooms, communication machine rooms and other key areas. The monitoring terminals are mainly set in the relevant professional duty rooms. If an accident occurs on the front line beyond the driver's visual range, the professional duty personnel need to report to the train dispatching after discovering the accident through the monitoring terminal, and then the train dispatching notifies the driver to implement emergency disposal. The driver has no technical means to timely grasp the line environment situation and alarm information beyond the visual range, and once an accident occurs, the driver can only passively wait for the dispatching instruction, which leads to slow response speed and passive disposal mode in this way of dealing with accidents, and the timeliness and effectiveness of the prevention and control of sudden risks need to be further improved.

[0003] Therefore, how to provide a heavy haul locomotive positioning, alarm information and monitoring video matching method which can help the driver to timely grasp the line environment situation and alarm information beyond the visual range so as to timely respond to the sudden danger is a technical problem to be solved by those skilled in the art.
