Description

School Zone Enforcement System using Driving Robot}

The present invention relates to a school zone enforcement system using a driving robot. More specifically, the driving robot is capable of monitoring the entire school zone while running on a cable arranged to connect a plurality of pillars, and the driving robot runs on the cable. Through this turning station, the driving robot's driving direction can be changed to a predetermined angle, thereby expanding the enforcement zone to the area surrounding the school zone, including the entire school zone. At the same time, the video captured by the camera is used to identify pedestrians or vehicles based on deep learning. When a pedestrian is found jaywalking, a warning signal is provided to the pedestrian and driver through a warning output means, and when a vehicle stopped in the school zone stays longer than a preset time, the vehicle's license plate is extracted and transmitted to the server. It's about the enforcement system.

A school zone, also called a child protection zone, refers to an area of the road near a school or around a crosswalk leading to a school where pedestrians may be present.

School zones are places where young students with poor attentiveness often come and go, so large and small traffic accidents involving young students frequently occur. To prevent such traffic accidents, the speed of cars in school zones is restricted. We are taking measures related to traffic safety.

Recently, fixed cameras have been mandatorily installed to monitor and control accidents that occur in school zones.

Fixed cameras have the disadvantage that they can only capture images of designated areas and do not capture images of other areas. In addition, the fixed cameras being installed are expensive, so installing them in all school zones is a huge cost burden.

Meanwhile, traffic accidents in school zones often occur due to pedestrians jaywalking at crosswalks and adjacent roads, so there is a great need to monitor and crack down on such jaywalking.

In addition, as the number of vehicles has recently increased, parking facilities have become scarce, resulting in frequent illegal parking of vehicles.

As a result, enforcement vehicles and a large number of manpower are deployed to crack down on vehicles illegally parked in school zones.

Illegal parking of vehicles is a factor that complicates road traffic, so there is a need to crack down on such illegal parking to improve traffic order and the living environment.

Moreover, not only illegal parking problems may occur in vulnerable crime prevention areas around schools and residential areas, but other security-related problems may also arise.

Therefore, there is an urgent need for the development of a system that not only monitors and cracks down on jaywalking of pedestrians and illegal parking of vehicles in the entire school zone and areas surrounding the school zone, but also performs an integrated crime prevention function.

Recently, fixed cameras have been mandatorily installed to monitor and control accidents that occur in school zones.

Fixed cameras have the disadvantage that they can only capture images of designated areas and do not capture images of other areas. Therefore, it is difficult to monitor and control the entire school zone with fixed cameras.

In addition, the fixed cameras being installed are expensive, so installing them in all school zones is a huge cost burden.

Meanwhile, traffic accidents in school zones often occur due to pedestrians jaywalking at crosswalks and adjacent roads, so there is a great need to monitor and crack down on such jaywalking.

In addition, as the number of vehicles has recently increased, parking facilities have become scarce, resulting in frequent illegal parking of vehicles.

As a result, enforcement vehicles and a large number of manpower are deployed to crack down on vehicles illegally parked in school zones.

Illegal parking of vehicles is a factor that complicates road traffic, so there is a need to crack down on such illegal parking to improve traffic order and the living environment.
