Abstract

A vehicle management apparatus and a method are provided to inform a sensing result and allow easy maintenance through wireless communication by installing a loop coil in a speed bump. A loop coil(102) is built in a movable speed-bump(100), and a sensing module senses a car through magnetic field change of the loop coil. A wireless module receives the sensing result from the sensing module and transmits it to an external device through wireless communication.

Description

Vehicle detection apparatus {Vehicle management apparatus and method}

The present invention relates to a vehicle detection device, and more particularly to a movable vehicle detection device.

In general, in order to determine various traffic conditions occurring on the road and to perform appropriate signal control, various detection sensors for collecting traffic information are buried on the road or installed on the roadside.

In particular, sensors for the purpose of detection in the traffic sector are used in a variety of sensors, such as an inductive loop detector and microwave and ultrasonic sensors, but mainly an inductive loop detector is used.

The inductive loop detector embeds a loop coil on a road surface and detects a vehicle by detecting a change in the magnetic field of the loop coil caused by the vehicle passing through the loop coil.

However, the inductive loop detector is frequently damaged due to vehicle damage, road surface breakage, or natural corrosion by embedding the loop coil on the road surface, which requires a lot of cost and effort for maintenance. There was a problem.

In addition, by embedding the loop coil of the inductive loop detector on the road, there is also an inconvenience that the detection area cannot be changed after construction.

Therefore, in the related art, there is an urgent need for the development of a technology capable of easily changing the detection area of the inductive loop detector or providing ease of maintenance.

The present invention is to solve the above-mentioned problems of the prior art, it is provided with a loop coil inside the movable speed bump device and to be able to notify the detection result through wireless communication to easily change the detection area or to facilitate maintenance It is an object of the present invention to provide a vehicle detecting apparatus that can be easily implemented.

Vehicle detecting apparatus according to the present invention for achieving the above object, a movable speed bump; A loop coil embedded in the movable speed bumps; A detection module detecting a vehicle by detecting a magnetic field change of the loop coil; And a wireless communication module that receives the detection result from the detection module and wirelessly transmits to an external device.

The present invention has the advantage of providing a loop coil inside the movable speed bump device and enabling the notification of the detection result through wireless communication to easily change the detection area or to easily perform maintenance.

The present invention provides a loop coil inside the movable speed bump device and makes it possible to notify the detection result through wireless communication.

The appearance of the vehicle detecting apparatus according to the preferred embodiment of the present invention will be described with reference to FIG. 1.

A plurality of loop coils 102 for detecting a vehicle are embedded in the movable speed bump device 100 made of rubber material. The loop coil 102 is a magnetic field is changed when the vehicle moves over the movable speed bump device 100, the change of the magnetic field is detected by a detection module not shown.

The configuration of the vehicle detection apparatus described above will be further described with reference to FIG. 2.

The vehicle detecting device includes a loop module 102 embedded in a movable speed bump device of a rubber material, a detection module 200 for detecting a change in a magnetic field of the loop coil 102, and a vehicle, a vehicle type, and the like. The wireless communication module 202 receives the detection result from the 200 and wirelessly transmits the information to the information collecting device, and a power supply unit 204 for supplying driving power to each part of the vehicle detecting device.

When the wireless communication module 202 is connected to a host through a network such as a USN (Ubiquitous Sensor Network), a wireless communication module such as a USN terminal module may be employed. When the wireless communication module 202 is connected to a host through a mobile communication network, the mobile communication module may be used. Modules may be employed.

The power supply unit 204 includes a solar cell array and a charger, and is configured to supply electric power to each unit of the vehicle detection apparatus by charging electrical energy according to solar energy.
