Description

Technical Field

[0001] The utility model relates to a high energy-saving control device for tunnel lighting, belonging to the field of tunnel lighting tools. Background Art

[0002] Tunnel lighting is an indispensable tunnel facility in high-speed tunnels. Tunnel lighting can improve the road conditions in the tunnel, improve the visual enjoyment in the tunnel, reduce driver fatigue, and help improve the tunnel's traffic capacity to ensure traffic safety. The cost of tunnel lighting is a considerable expense in the tunnel operating costs.

[0003] However, in actual tunnel operation, tunnel lighting is usually on 24 hours a day, regardless of whether there are vehicles passing through the tunnel. From a low-carbon and environmental protection perspective, this does not meet the requirements of energy conservation and emission reduction.

[0004] Generally, high-speed tunnel lighting often uses the tunnel lights to work in a long-lasting manner. According to our on-site investigation and review of relevant information, we found that there are very few tunnels equipped with relevant energy-saving devices. The main reasons are: first, the existing energy-saving lighting control equipment is unstable, and the controller often crashes or is damaged, which increases the maintenance workload; second, the crash or damage of the controller will cause the tunnel lighting to lose power and the tunnel will lose lighting, posing a safety hazard to the passage of vehicles; at the same time, the energy-saving effect of the existing lighting devices is poor.

[0005] That is, there is a need for a tunnel lighting device that can ensure the tunnel lighting effect while also having a high energy-saving effect. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a high energy-saving control device for tunnel lighting, which can ensure the tunnel lighting effect while also having a high energy-saving effect; and can overcome the shortcomings of the prior art.

[0007] The purpose of this utility model is achieved through the following technical solutions:

[0009] The computer in the above-mentioned master control center is provided with LED light group brightness adjustment values ​​corresponding to the tunnel section brightness interval values ​​and the vehicle flow interval values.

[0010] The above-mentioned master control center computer controls the LED driver through RS communication protocol technology.

[0011] The aforementioned vehicle detector is a millimeter-wave radar, and the millimeter-wave radar and camera device are both connected to a radar-vision fusion edge computing unit.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model can detect the brightness of each section of the tunnel and the size of the vehicle flow through the light brightness detector and the vehicle detector, and obtain data. Then, the LED driver is controlled by the computer of the master control center to perform stepless dimming and adjust the brightness. In this way, it can be adjusted at any time to ensure the lighting effect of the LED lamp group while saving energy to the greatest extent. The energy-saving effect is significant. At the same time, the main controller, backup controller and pulse control are redundantly designed to overcome the problem of unreliable operation of the existing energy-saving controller, and achieve the purpose of both energy saving in the tunnel and stable and reliable operation.

[0014] 2.
