Problems solved by technology

[0003] Metal halide lamps are commonly used in existing tunnel lighting systems. Metal halide lamps have a relatively short lifespan due to their high brightness and small size. Less than 1000 hours, the life of imported metal halide lamps can reach thousands of hours
[0004] Another disadvantage of metal halide lamps is that it is difficult to start and must be triggered by a special trigger; the brightness increases gradually after starting, if the starting energy is too large and the starting speed is too fast, it will affect the life of the bulb

Embodiment Construction

[0025] Preferred embodiments of the present invention are described in detail below.

[0026] The LED tunnel lamp energy-saving dimming control system and method of the present invention aim at the existing dimming means, use the dimming system to control the LED tunnel lamp, and collect traffic conditions, analyze lighting requirements, and provide multi-mode, multi-level adjustment of the brightness of the LED tunnel , in line with the tunnel safety, energy-saving lighting requirements.

[0027] Such as figure 1 Shown is a structural schematic diagram of the LED tunnel light lighting and dimming control system of the present invention, which includes a central system, which can be set as a PC, and is sequentially connected by communication with a first brightness sensor for collecting brightness outside the tunnel, and a vehicle flow detection system. As well as the vehicle speed detection system and a second brightness sensor used to collect the brightness in the cave are ...

Abstract

The invention discloses an energy-saving light regulating control system and method for LED tunnel lamps. The system comprises a plurality of tunnel lamps used for tunnel illumination. The system is also provided with a central system used for controlling the on / off and brightness regulation of the tunnel lamps. The central system also connects and controls a plurality of regional PLC controllers; each regional PLC controller connects and controls at least one LED tunnel lamp within a distance inside the tunnel, and is used for regulating the brightness of the LED tunnel lamps of each section; and the central system is also connected with a first brightness sensor used for acquiring the brightness outside the tunnel and a second brightness sensor used for acquiring the brightness inside the tunnel. As the system and the method adopt the central system for the group control on the LED tunnel lamps in the tunnel, the system and the method realize the energy-saving and intelligent control of the LED tunnel lamps by combining the feedback of the brightness outside the tunnel and regulation results.

Description

technical field [0001] The invention relates to a tunnel light control system and method, in particular to a tunnel light energy-saving and intelligent dimming control system and method. Background technique [0002] With the expansion of the existing technology of road and railway construction, the total mileage of the tunnel is increasing significantly, and if the lighting in the tunnel is kept on all day long, its energy consumption is very large, and its life will also be due to The overall time of continuous lighting is much shorter than that of intermittent lighting. Therefore, it is necessary to control the lighting system in the tunnel in order to balance the needs of energy saving and safety. [0003] Metal halide lamps are commonly used in existing tunnel lighting systems. Metal halide lamps have a relatively short lifespan due to their high brightness and small size. Less than 1000 hours, the life of imported metal halide lamps can reach thousands of hours. [...
