Description

OVERLOADED VEHICLE CONTROLLING SYSTEM AND METHOD}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an overload vehicle enforcement system, and more particularly, to an overload vehicle enforcement system and method for controlling a restricted vehicle on a general road, national road, bridge, and the like.

In the conventional overload cargo truck control, the overweight cargo truck is caught on the weighing apparatus installed next to the road to measure the weight, and then the overload cargo is determined. The weighing device used in the related art only plays the role of an electronic scale, and all the judges had to determine whether the overload was judged. That is, the cargo truck to be weighed up to the weighing device to be measured to stop the cargo truck that appears excessively over the cargo truck running on the road to lead to climb to the weighing device.

Therefore, in order to crack down on an overloaded cargo truck, a crackdown agent had to be required, and since the passing vehicle had to be placed on a weighing apparatus off the road, it was difficult to crack down another cargo truck during measurement because of a time delay. First of all, the crackdown agent stayed around for 24 hours, so it was difficult to crack down, so the crackdown is usually performed only during the daytime, which is a working time. In addition, cargo trucks carrying heavier loads per unit volume were apparently less bulky, thus avoiding the eyes of police officers.

As a result, the roads became sore and lost and rugged here and there, creating a risk of accidents for small vehicles such as cars. In addition, the frequent maintenance of the roads caused a problem of wasting people's taxes. In particular, the problems caused by overload trucks cause more problems in the damage of facilities such as bridges and overpasses, and the sudden accumulation of fatigue loads caused by overload trucks can lead to large casualties such as the sudden collapse of Seongsu Bridge. do. Therefore, the crackdown agents would take a form of accidental crackdown in order to prevent any further operation of the overload cargo truck. That is, while patrolling the road by using the mobile weighing apparatus, the cargo truck that appeared to be overload was stopped and immediately weighed to determine whether it was overloaded. However, it is impossible to protect the road from overload trucks because it is impossible to crack all vehicles passing through these uninterrupted 24 hour roads. Therefore, it is necessary to develop a system that can control whether a vehicle exceeds the permissible weight due to overload for all vehicles passing through the road for 24 hours without the presence of enforcement personnel.

Accordingly, the present invention has been made to solve the above problems of the prior art, by using a CCTV and equipment that can measure the weight at unmanned and manned checkpoints to crack down on restricted vehicles on general roads, national roads and bridges An object of the present invention is to provide an overload vehicle control system and method capable of controlling a vehicle charged with overload by measuring a weight of a running vehicle and photographing a license plate of the vehicle.

In order to achieve the above object, the present invention is installed in front of the overload checkpoint, to measure the weight of the vehicle traveling on the road, output the suspected vehicle recognition signal in accordance with the measured weight of the vehicle, A high speed shaft relay device that detects and outputs an abnormal driving detection signal; It is installed between the overload checkpoint and the high speed shaft relay device at a predetermined distance away from the high speed shaft relay device, and overloaded in response to at least one of the suspected vehicle recognition signal and the abnormal driving detection signal from the high speed shaft relay device.
