The invention provides a dimmable tunnel LED (Light-Emitting Diode) illumination energy-saving control system and method, belonging to the technical field of illumination energy-saving control in a tunnel. The dimmable tunnel LED illumination energy-saving control system comprises an LED tunnel lamp, a PWM (Pulse Width Modulation) dimmable digital power source, a region PLC (Programmable Logic Controller), a main control PLC, a first infrared vehicle detector, a second infrared vehicle detector, a first illumination detector, a second illumination detector, a radar vehicle detector and an external PLC. The dimmable tunnel LED illumination energy-saving control method is carried out according to the following steps of: 1, collecting a vehicle flow signal; 2, carrying out frequency modulation and dimming; 3, defining a name; 4, adjusting an illumination parking vision distance; 5, judging whether a vehicle passes through a tunnel or not, and determining the light intensity of a tunnel entrance section; and 6, adjusting the light intensity coefficient of the LED tunnel lamp. The dimmable tunnel LED illumination energy-saving control system and method provided by the invention have the advantages that the functions of illumination on demand, long-distance monitoring and automation are realized, energy-saving efficiency is improved, a real-time operation electric energy consumption curve is monitored, unattended operation is realized and labor cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of energy-saving control of lighting in tunnels, and in particular relates to a system and method for energy-saving control of LED lighting in dimmable tunnels. Background technique [0002] With the vigorous development of highway construction, especially highway construction, the mileage of tunnel lighting is getting longer and longer, and the power consumption is increasing day by day, resulting in increasingly prominent issues of tunnel driving safety and lighting energy saving: 1. Driving safety. The process of vehicles passing through the tunnel is a bright-dark-bright process. In the process of alternating light and dark, human eyes often produce "black hole effect" and "white hole effect", which is very prone to traffic accidents; 2. Lighting energy saving. Most of the tunnels are distributed in mountainous areas, and there are few vehicles at night. However, the control system of the existing tunnel...
