The following steps are also included: A1: When the abnormal situation monitoring unit detects an abnormal situation, the alarm is activated through the intelligent processing center, and then the staff checks the corresponding video information through the human-computer interaction module. Exception is invalid.

A2: If the abnormal situation is a traffic accident, notify the public security, fire and medical institutions through the alarm module, fire module and medical module. At the same time, the traffic accident emergency module controls the broadcasting equipment in the section where the traffic accident occurs to broadcast the traffic accident information.

A3: If the abnormal situation is a fire, the public security agency, fire agency and medical agency will be notified through the alarm module, fire module and medical module. At the same time, the fire smoke emergency module controls the broadcasting equipment around the fire area to broadcast fire information.

A4: If the abnormal situation is an illegal act or a specific person, the public security agency, fire agency and medical agency will be notified through the alarm module, fire module and medical module. At the same time, the PTZ camera is controlled by the tracking module to track target personnel and specific personnel. Traffic accidents, fires, illegal acts, and specific personnel are automatically identified through street lights distributed in the city, which improves the safety of the city and the sense of security of residents.

A2 also includes: when a traffic accident occurs and the vehicle needs to be navigated, the initial position and target position of the vehicle are transmitted to the navigation module through the navigation client, and multiple pre-selected routes from the initial position of the vehicle to the target position are generated by the pre-selected route generation module , and then the pre-selected routes with traffic accidents are excluded through the traffic accident route exclusion module, and the rest of the pre-selected routes are sent to the route segmentation unit. Then the route segmentation unit divides the pre-selected route into multiple basic road sections according to the road intersections identified by the node identification unit, and then obtains the average vehicle speed of the basic road sections through the average vehicle speed calculation unit, and then obtains the ideal driving of the pre-selected route through the summation unit Finally, the preselected route with the shortest ideal travel time is sent to the navigation client as the navigation route through the route selection module. The vehicle is guided by the navigation module and the navigation client, so that the vehicle avoids congested road sections, can automatically clear the traffic, and can improve the user experience of the navigation client.
