Description
Technical Field
[0001] This utility model relates to the field of railway tunnel safety monitoring technology, specifically to a lighting image acquisition device for railway tunnels. Background Technology
[0002] During operation, railway tunnels are subject to various human and environmental factors, which may cause tunnel disasters of varying degrees, thus affecting the safety and stability of the tunnel structure. As an important component of the tunnel, the railway tunnel lighting system mainly serves to facilitate the maintenance and upkeep of facilities such as work, power, traction power supply, communication, and signaling systems installed within the tunnel. In the past, railway tunnel lighting equipment used electrodeless lamps and sodium lamps, which consumed a lot of power and had a short lifespan. In addition, the current monitoring of railway tunnel conditions mainly relies on manual track inspections during track windows or periodic inspections by inspection vehicles. Manual inspections require a large number of personnel, are inefficient, and costly. Therefore, it is necessary to design a lighting image acquisition device for railway tunnels.
