Embodiment Construction

[0025] The present invention will be further described below in conjunction with embodiment.

[0026] In order to solve the optimization control problem of tunnel lighting energy saving and safety, the present invention according to figure 1 Build a tunnel lighting monitoring system, including central monitoring host, brightness detection unit, vehicle flow rate monitoring unit, ambient temperature sensor, communication bus, area controller, single lamp control power supply with communication bus, and LED lamps. The central monitoring host adopts an industrial computer, runs the central monitoring management software and communication interface software, and transmits the detection parameters of the vehicle flow rate detection system, brightness meter and temperature sensor to the central monitoring host through the communication bus. The central monitoring host sends the area control command to each area controller through the communication interface, and then controls and ad...

Abstract

The invention belongs to the technical field of lighting equipment in a tunnel, and relates to an automatic control method for tunnel LED lighting based on an intelligent expert illuminance curve. The method comprises the following steps: 1) detecting brightness outside the tunnel to obtain a brightness value outside the tunnel, and compensating the brightness value to obtain the brightness at an inlet section; 2) dividing transition sections, and setting an initial brightness reference value of each section based on the brightness at the inlet section; 3) establishing an expert database, reasoning input information such as tunnel length, tunnel height, the brightness outside the tunnel, running speed, traffic flow and traffic modes, and adjusting the corresponding brightness reference value of each section; 4) carrying out smooth processing on brightness distribution of the transition sections; 5) generating a complete dynamic brightness demand curve; and 6) realizing brightness feedback adjustment on the overall LED tunnel lamps according to the brightness demand curve and part of brightness detection values in the tunnel. The automatic control method of the invention can prolong service life of the lamps in the tunnel, reduce maintenance cost and save energy consumption.

Description

technical field [0001] The invention belongs to the technical field of lighting equipment in tunnels, in particular to an intelligent control method for tunnel lighting. Background technique [0002] For a long time, conventional products such as high-pressure sodium lamps, fluorescent lamps, high-pressure mercury lamps, and halogen lamps that have been used in tunnel lighting have become less and less suitable for people because they contain harmful substances such as mercury, and must be powered on all year round in the tunnel, which consumes a lot of energy. In pursuit of environmental protection and energy saving, people urgently need to find new energy-saving and environment-friendly lighting sources. [0003] As a new type of solid light source, LED lamps are energy-saving, long-life and high-utilization. Another superior feature is the instantaneous controllability of brightness. This feature not only enables lower energy consumption and longer life, but also lower ...
