Embodiment 1
[0056] A parameter optimization model of staggered lighting in the middle section of a highway tunnel based on light distribution data. The specific steps are as follows:
[0057] Step 1: Determine the calculation area, the number of lamps and the coordinate system for calculation
[0058] Take the two adjacent lamps, that is, the road area between the two lamps on both sides of the tunnel road as the calculation area, and the points in this area are the calculation points. At the same time, consider the two adjacent lamps outside the calculation area in the calculation area Calculate the influence of point illuminance. There are 4 lamps that affect the illuminance of the calculated point; the longitudinal direction of the tunnel is the X axis, the transverse direction of the tunnel is the Y axis, the height direction is the Z axis, and the center point of the calculation area is the origin to establish a three-dimensional rectangular coordinate. Department, as attached figure 2 ...

The invention discloses a highway tunnel middle section staggered lamp distribution parameter optimization model based on lamp light distribution data. According to lamp light distribution data, horizontal illumination and total horizontal illumination calculation models generated by all lamps at any point in a highway tunnel calculation area are separately built, tunnel road surface illumination, brightness, illumination evenness level, strobe and the like are used for meeting traffic security requirements and serve as optimizing constraint conditions, smallest total power consumption in the middle section of the tunnel serves as a goal, the model is constructed, optimizing lamp distribution parameters are obtained in a staggered lamp distribution mode, and therefore an illumination lamp fully exerts the illumination capacity and achieves energy conservation of an illumination system during the working service life of the illumination lamp. The highway tunnel middle section staggered lamp distribution parameter optimization model based on the lamp light distribution data has the advantages that according to the lamp light distribution data, the lamp distribution parameters of the lamp are optimized, when the lamp is mounted according to the optimized lamp distribution parameters, on the premise that the illumination system meets the traffic security requirements, the total energy consumption is minimum, and therefore the energy consumption cost and total cost of tunnel operation are reduced, and the model has obvious economic benefits and social benefits.
Description
Technical field [0001] The invention relates to a parameter optimization model of staggered arrangement of lights in the middle section of a highway tunnel based on light distribution data of lamps, and belongs to the research field of energy-saving lighting of 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 safety of expressway tunnels. At the same time, the tunnel lighting system is a high-energy system in expressway tunnels. The cost of lighting energy consumption accounts for the operating cost of expressway tunnels. A large proportion. According to the "Detailed Rules for the Lighting Design of Highway Tunnels", tunnels longer than 100m should be illuminated. Statistics on the electricity 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 highway construction in...
