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, and there are 4 lamps in total. It affects the illuminance of the calculation point; take the longitudinal axis of the tunnel as the X axis, the horizontal 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-dimensional rect...

The invention discloses a lamp light distribution data-based arch crown lateral deviation lamp distribution parameter optimization method for a middle section of a road tunnel. Calculation models for horizontal illuminance and total horizontal illuminance generated by each lamp at any point in a road tunnel pavement calculation region are built according to lamp light distribution data; an optimization model is built by taking tunnel pavement illuminance, brightness, illuminance uniformity, stroboflash and the like meeting traffic safety requirements as optimization constraint conditions and taking minimum total power consumption of illumination of the middle section of the tunnel as a goal; optimized lamp distribution parameters of a lamp distribution mode are obtained; and illumination lamps fully exert illumination capabilities during a working life period, so that the energy-saving effect of an illumination system is achieved. According to the method, the lamp distribution parameters of the lamps are optimized according to the light distribution data of the selected lamps; and when the lamps are mounted according to the optimized lamp distribution parameters, the illumination system has minimum total energy consumption on the premise of meeting the traffic safety requirements, so that the energy consumption cost and the total cost of tunnel operation are reduced; and the method has remarkable 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...
