Embodiment 1
[0058] A method for optimizing the lighting parameters of the side-biased lighting of the vault in the middle section of the highway tunnel based on the light distribution data of the lighting fixtures. The specific steps are as follows:
[0059] Step 1: Determine the calculation area, the number of lamps used for calculation and the coordinate system
[0060] The calculation area is the road surface area between two adjacent lamps, and the points in this area are the calculation points. At the same time, the influence of the two adjacent lamps outside the calculation area on the calculation point illuminance in the calculation area is considered. There are 4 lamps in total. It has an impact on the illuminance of the calculation point; take the longitudinal direction of the tunnel as the X axis, the transverse direction of the tunnel as the Y axis, and the height direction as the Z axis, and take the center point of the calculation area as the origin to establish a three-dimens...

The invention discloses a method for optimizing the parameters of lamps arranged on the side of the vault in the middle section of a highway tunnel based on the light distribution data of lamps. The horizontal illuminance calculation model is based on the tunnel road surface illuminance, brightness, illuminance uniformity, stroboscopic, etc. to meet the traffic safety requirements as optimization constraints, with the goal of minimizing the total lighting power consumption in the middle section of the tunnel, an optimization model is established, and the lighting arrangement method is obtained Optimize the parameters of lighting arrangement, so that lighting fixtures can give full play to their lighting capabilities during their working life, and realize the energy saving of lighting system. According to the light distribution data of the selected lamps, the present invention optimizes the lighting parameters of the lamps. When the lamps are installed according to the optimized lighting parameters, the lighting system will minimize the total energy consumption under the premise of meeting the traffic safety requirements, thereby reducing tunnel operation. The energy consumption cost and the total cost have obvious economic and social benefits.
Description
technical field [0001] The invention relates to a parameter optimization method for lamp distribution on the side of the vault in the middle section of a highway tunnel based on the light distribution data of lamps, and belongs to the research field of energy-saving lighting technology for highway tunnels. Background technique [0002] Tunnel lighting is an equipment system that must be installed in expressway tunnels. It is the basic guarantee for the operation safety of expressway tunnels. At the same time, tunnel lighting systems are high-energy consumption systems in expressway tunnels. The cost of lighting energy consumption occupies a large part of the operating costs of expressway tunnels. A large proportion. According to the "Design Rules for Highway Tunnel Lighting", all tunnels with a length greater than 100m should be equipped with lighting. Statistics on power consumption of highway tunnels show that the annual electricity cost per kilometer of the tunnel is mor...
