Study on Luminance Detection Route for Highway Tunnel Based on Ant Colony Algorithm
In order to solve the problem of winding and inefficient travel routes caused by scattered tunnels in the process of detecting lighting luminance in ordinary trunk highway tunnels,a suitable route for traversing tunnel lighting luminance detection is found.Taking the latitude and longitude geographic coordinate system as the study object,the latitude and longitude geographic coordinate system of ordinary trunk road tunnels is determined through data collection and assistance with electronic map tools such as Baidu or Gaode Map.A database table of latitude and longitude spherical coordinate system is established based on the division of ordinary trunk road tunnels in each province or the distribution of tunnels in the detection area,and mathematical calculations are carried out by using map analysis software tools.The established latitude and longitude spherical geographic coordinate system are transformed into a two-dimensional projection coordinate system,the database table of the two-dimensional projection coordinate system is calculated by using ant colony algorithm,and the parameters are selected such as the number of ant sets,pheromone importance factor,heuristic function importance factor,pheromone volatility,pheromone intensity,maximum iteration number,etc.Start polling access calculations from different tunnels,traversing all the common trunk road tunnels with illumination detection and generating an implementable travel route for common trunk road tunnel detection,which has no detour in the course of the route.The tunnel lighting is tested according to the route after the starting point,and then comes back to the starting point after the test.The result shows that in solving the tunnel luminance detection route planning,it is reasonable,scientific and easy to realize that the method of generating and sorting tunnel luminance detection route is based on the combination of longitude and latitude coordinate transformation,ant colony algorithm and electronic map tool.The method has been applied in the illumination detection of 30 tunnels of a certain area in a province.
