The invention provides an illuminating and symmetrical lamp-distribution parameter optimizing method of a highway tunnel middle-section. The method comprises the following steps of constructing horizontal illuminance and total horizontal illuminance generated in any point in a highway tunnel pavement calculation area of all lamps respectively according to lamp light distribution data, regarding the conditions of tunnel pavement illuminance, brightness, the uniformity ratio of illuminance, stroboflash and the like which satisfy traffic safety requirements as optimization restriction conditions, setting a goal of making the illuminating total power dissipation of the tunnel middle-section minimum, and building a symmetric lamp-distribution parameter optimization model based on the lamp light distribution data to obtain optimized lamp-distribution parameters in a symmetrical lamp-distribution mode. The illuminating and symmetrical lamp-distribution parameter optimizing method of the highway tunnel middle-section has the advantages that the lamp-distribution parameters of lamps are optimized according to the light distribution data of the selected lamps, when the lamps are installed according to the optimized lamp-distribution parameters, in an illuminating system, on the premise that the traffic safety requirements are satisfied, the total energy dissipation is minimum, accordingly the power dissipation cost and the total cost in tunnel operation are lowered, and the optimizing method has obvious economic benefit and social benefit.
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...
