Embodiment 1
[0056] A parameter optimization model for staggered lighting arrangement in the middle section of highway tunnel based on light distribution data of lamps. The specific steps are as follows:
[0057] Step 1: Determine the calculation area, the number of lamps used for calculation and the coordinate system
[0058] Take two adjacent lamps, that is, the road surface area between one lamp on both sides of the tunnel road surface as the calculation area, and the points in this area are the calculation points, and at the same time, consider the pair of adjacent lamps outside the calculation area in the calculation area To calculate the influence of point illuminance, there are 4 lamps that have 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 thre...

The invention discloses an optimization model of staggered lamp arrangement parameters in the middle section of a road tunnel based on light distribution data of lamps, and calculates the horizontal illuminance and total horizontal illuminance generated by each lamp at any point in the road surface calculation area of the road tunnel according to the light distribution data of the lamps. The model is based on the tunnel road surface illuminance, luminance, illuminance uniformity, strobe, etc. to meet the traffic safety requirements as optimization constraints, and the goal is to minimize the total lighting power consumption in the middle section of the tunnel, and establish a model to obtain the optimal lighting parameters of the staggered lighting method , so that the lighting fixtures can give full play to their lighting capabilities during their working life, and realize the energy saving of the lighting system. The remarkable effect of the present invention is: according to the light distribution data of the selected lamps, the lighting parameters of the lamps are optimized. When the lamps are installed according to the optimized lighting parameters, the lighting system will have the minimum total energy consumption under the premise of meeting the traffic safety requirements. , thereby reducing the energy consumption cost and total cost of tunnel operation, which has obvious economic and social benefits.
Description
technical field [0001] The invention relates to a parameter optimization model for staggered lamp arrangement in the middle section of a road tunnel based on light distribution data of lamps, and belongs to the research field of road tunnel lighting energy-saving technology. 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 more than 400,000 yuan; with the ac...
