Description

A Device for Warning Excess Width of Loaded Freight and Method therefor}

The present invention relates to an over-width warning device and method of loading cargo, in particular to detect whether the width of the cargo loaded on a vehicle entering a toll gate, such as a highway exceeding the limit to generate an alarm sound and warning and identify the vehicle. An apparatus and a method for overload alarm of a cargo to obtain an image which can be obtained.

Toll gates, such as highways, measure or detect the overload or excess of cargo loaded on vehicles entering highways in order to protect roads and their facilities and reduce the risk of traffic accidents.

In addition, there are overpasses, overpasses, three-dimensional intersections, and tunnels on the road, and these facilities have a limited height that can pass through them, so that vehicles that have loaded cargo beyond these heights will have facilities and cargo May cause a conflict with the

In order to prevent such an accident, vehicles exceeding the height of roads such as toll gates are cracked down by an electronic system to prevent facility protection and traffic accidents.

In addition, excessive weight is applied to a part of the road that is in contact with the wheel of the vehicle due to the weight of the vehicle that is overloaded with cargo, and the part is crushed and damaged, which impacts the wheel of the vehicle that runs at high speed, thereby causing traffic such as puncture of the wheel. It can provide a cause for an accident.

Therefore, when a freight car enters a toll gate, a separate dedicated driveway is installed to measure the overload of the freight vehicle by an electronic system, and the passage is restricted in case of violation of regulations.

Although the electronic system for measuring the weight and height of the vehicle is installed at the left and right sides of the entrance of the vehicle, only the overload and height of the vehicle are measured, and the width is not measured. Therefore, the cargo loaded on the vehicle protrudes to the left or the right. If exceeded, it collided with an electronic system that measured weight and height or with a booth to collect tolls, threatening the workers in the booth.

However, in the past, only vehicle overweight and height exceeded were measured and limited, so it was difficult to detect and control vehicles exceeding the width, and various traffic facilities were destroyed, resulting in large property losses. Not only does it pose a danger, but it impedes the flow of traffic by interfering with the driving of adjacent vehicles, thereby providing a cause of traffic accidents, and when a traffic accident occurs, it greatly delays the driving of vehicles such as restriction of traffic. There was an inconvenience.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide an apparatus and method for exceeding the width of a load cargo for detecting and alarming whether a width of a load loaded on a vehicle exceeds a specified width.

It is another object of the present invention to provide an apparatus and a method for overload warning of a load cargo used for photographing an identification image of a vehicle in which the width of the loaded cargo exceeds a prescribed width and using it as a basis for a fine.
