Henan coal pull vehicle GPS Which is better? Double GPS positioning system can detect every unloading switch working state, when the vehicle arrives at the destination stop, you can put a time unloading time, place and other recorded; when in a non-legal area Depot GPS positioning detected When installing gps car unloading switching helpful, Double GPS positioning and monitoring platform that can monitor a non-normal operations install gps car locator, and you can see the specific circumstances of the car according to the car's camera, thereby improving coal mine transportation regulatory standards. Henan coal truck GPS positioning system, GPS monitoring system pulling coal cars, power plants and coal car GPS management system 1) fixed-line alarm to prevent a change coal coal truck every day job is running the route is relatively fixed, which compares easy running route for coal trucks per plan. We fixed coal truck transportation task should take to complete the true route, through GPS positioning Double track playback, preserved on a map, set to a fixed line. 2) Illegal unloading area open switch alarm Double GPS positioning system can detect the status of each job unloading switch installation gps, when the vehicle arrives at the destination stop, you can put a time unloading time, place and other recorded; When the non-legal area Depot GPS positioning to detect unloading switch action, Double GPS positioning platform can be monitored non-normal operation this time, and you can see the specific circumstances of the car according to the car's camera, thereby improving coal mine transportation regulatory standards. 3) Double speed alarm use GPS positioning overspeed alarm gps locator free installation, we can set the speed limit for each vehicle, according to the regional road they walk past the speed limit, respectively, when the vehicle is in operation over After setting the speed limit, the system will carry out sound and light alarm. 4) historical track playback function for some vehicles in question, can be related to the historical track playback function can solve the problem of historical trajectory of the head. Zhengzhou Double Electronic Car GPS electronic map of the specific content should include the following: (1) road network. It is the most important part of the vehicle monitoring and dispatching system electronic map is the source of data on the basis of the entire electronic map, but also the path planning, map matching, map assisted positioning algorithm. In addition to the physical characteristics of the road and geometric properties, as well as the expression of topological relations section of the road network, the speed limit, the type of vehicles, the single existing line, closed to traffic routes, traffic information and other related prohibited turn. (2) blocks. (3) river and rail. (4) geographic features, parks, green land and lakes.
