Example Embodiment

[0025] The preferred embodiments of the present invention will be described in detail below.

[0026] The LED tunnel light energy-saving dimming control system and method of the present invention use the dimming system to control the LED tunnel lights according to the existing dimming means, and through collecting traffic conditions, analyzing the lighting demand, providing multi-mode and multi-level adjustment of the brightness of the LED tunnel , In line with the safety and energy-saving lighting requirements of the tunnel.

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

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. [...
