Embodiment Construction

[0024] The present invention is based on an advanced RISC microprocessor, uses high-precision intelligent detection means, detects the intensity of the light at the entrance and exit of the tunnel in real time through the light detectors distributed in the tunnel, and feeds the processed data back to the control center. and then control various tunnel lamps in different positions to realize the brightness control of LED tunnel lamps in different positions, and finally achieve the purpose of saving energy.

[0025] Such as figure 1 and figure 2 As shown, the LED tunnel lighting intelligent control system includes a control center PC, a brightness sensor / temperature sensor / current sensor, a tunnel lighting controller, a transmission medium, a relay amplifier, a drive control module, a constant current drive power supply, and a tunnel lighting. The brightness sensor, temperature sensor and current sensor are connected to the tunnel lamp controller through the transmission mediu...

Abstract

The invention provides an intelligent control system for LED tunnel lamps and a method for controlling the LED tunnel lamps. The system comprises a control center PC computer, a tunnel lamp controllerand lamps, wherein a brightness/temperature/current sensor is connected with the controller via a transmission medium; the control center PC computer is connected with a plurality of drive control modules via the controller and a bus structure; and each drive control module is connected with a constant-current driving power supply of each LED tunnel lamp. Therefore, the system detects the intensity and weakness of light at the entrance and exit of a tunnel in real time via optical detectors distributed in the tunnel by applying highly accurate intelligent detection measure based on an advanced RISC microprocessor, and feeds processed data back to a control center; the control center processes the data and controls various tunnel lamps at different positions so as to control the brightnessof the LED tunnel lamps at different positions and finally achieve the aim of saving energy source.

Description

technical field [0001] The invention relates to a tunnel lamp control system for lighting and a control method thereof, in particular to an LED tunnel lamp intelligent control system and a control method using a high-power and high-brightness light-emitting diode as a lighting source, and belongs to the technical field of semiconductor lighting. Background technique [0002] Tunnels are an important part of expressways, and tunnel lighting systems are essential guarantees for vehicles to safely enter, pass and leave tunnel areas. At present, the lighting of long-distance tunnels is divided into entrance section, transition section, basic section, and exit section. The lamps of each section are divided into three types: emergency lights, full-day lights and enhanced lights according to their functions. In addition to being used as emergency lighting during power outages, the emergency lights also serve as full-day lighting. The full-day lights work 24 hours a day, and the enh...
