The present invention provides a method for optimizing the parameters of symmetrical lighting arrangement in the middle section of a highway tunnel, which includes the following steps: respectively establishing the horizontal illuminance and the total horizontal illuminance produced by each lamp at any point in the calculation area of the road surface of the highway tunnel according to the light distribution data of the lamps, and taking the tunnel Road surface illuminance, luminance, illuminance uniformity, strobe, etc. meet traffic safety requirements as optimization constraints, and aim at the minimum total lighting power consumption in the middle section of the tunnel, establish a symmetrical lighting parameter optimization model based on light distribution data of lamps, and obtain a symmetrical Lighting mode optimization lighting parameters. The advantages are: the present invention optimizes the lighting parameters of the lighting fixtures according to the light distribution data of the selected lighting fixtures. When the lighting fixtures are installed according to the optimized lighting parameters, the lighting system will minimize the total energy consumption under the premise of meeting traffic safety requirements, thereby Reducing the energy consumption cost and total cost of tunnel operation has obvious economic and social benefits.
Description
technical field [0001] The invention belongs to the technical field of tunnel lighting, and in particular relates to a parameter optimization method for symmetrical lighting arrangement in the middle section of a road tunnel. Background technique [0002] Tunnel lighting is an equipment system that must be installed in expressway tunnels, and it is the basic guarantee for the operation safety of expressway tunnels. According to the "Design Rules for Lighting of Highway Tunnels", tunnels with a length greater than 100m should be equipped with lighting systems. At the same time, the tunnel lighting system is a high energy consumption system in the expressway tunnel, and the cost of lighting energy consumption occupies a large proportion of the operating cost of the expressway tunnel. Statistics on power consumption of highway tunnels show that the annual electricity cost per kilometer of the tunnel is more than 400,000 yuan; with the acceleration of the construction of express...
