According to the device, the system and the method, improvements are made on a traditional navigation technique, the weather forecast information is adopted as one of main factors considered for navigation, a traditional navigation route is regulated and modified in real time through the weather forecast information, and the network map is labeled with the weather forecast information of each area in real time on the basis of area distinguishing and time distinguishing, thus achieving real-time navigation based on weather conditions and enhancing predictability and reliability of travel information.

The invention provides a road network change detection method, and belongs to the technical field of intelligent transportation. The method comprises the steps of: step S01, collecting vehicle trajectory data points, and sorting the same according to a time sequence; step S02, calculating a difference value between the two adjacent vehicle trajectory data points in time, determining and retainingthe vehicle trajectory data points of intersection turning; step S03, performing clustering on the vehicle trajectory data points of intersection turning to identify an urban intersection and an intersection type; and step S04, comparing the intersection information obtained in the step S03 with the intersection information on a map, and when it is determined that a new road or a disappearing roadexists, sending a road change signal to a surveying and mapping department terminal, so that the surveying and mapping department terminal updates the road network map. According to the road networkchange detection method provided by the invention, the detection information is comprehensive, new roads can be discovered, and disappearing roads can also be discovered, so that real-time detection of road network changes is really achieved.

The invention discloses a dynamic differential positioning method for a mobile communication terminal based on map matching. The method comprises the following steps: obtaining surrounding base station information; using the base station information database to find the latitude and longitude coordinates of the surrounding base station points according to the obtained base station information; calculating the latitude and longitude coordinates of the mobile communication terminal; marking the location of the mobile communication terminal on the map according to the latitude and longitude coordinates of the mobile communication terminal, After removing the historical location coordinates that deviate greatly from the fitting trajectory, fit the remaining historical locations to form a motion trajectory; compare the direction angle and distance difference between the fitted motion trajectory and the road on the map, match the closest street road, and remove the motion The location point on the trajectory that deviates greatly from the matched road; draw the standard path on the map, and repeat the preceding steps. The present invention adopts the method of difference to carry out data fitting, so that the positioning is more accurate, and at the same time, the cost of positioning is also reduced, and the problem of difficult positioning and navigation of the base station is effectively solved.

The invention discloses a method and device for navigating a handling robot based on laser guidance map construction. The method includes the steps of: acquiring a topology map, a geometric map of an operation area and a target destination of a handling robot; The positioning information of the transporting robot, wherein the positioning information includes the position coordinates and self-positioning posture of the transporting robot; according to the positioning information and the topological map, a global planning path is generated; The grid map associated with the position coordinates of the robot, and the instructions for indicating the movement of the handling robot are generated according to the global planning path.
