Integral problems such as installation complexity, road cutting problem during installation, road line disconnection between roof coil and car detector during road construction after installation, and existing roof coil when re-packing the road The present invention relates to an integrated roof type vehicle detector including a roof coil and a parking information system using the same.

The conventional roof type vehicle detection device, which has been used most widely in the world for decades, is a loop coil cut and installed to detect traffic information such as the presence or absence of a vehicle, the speed of the vehicle, and the type of the vehicle. Coil) And the loop type vehicle detection device in the form of a loop detector that detects the presence or absence of a vehicle by changing the inductance by connecting the loop coil with the lead line has been used the most. The reason is that the change in inductance of the roof coil is not affected by road freezing, change in temperature and humidity, change in amount of sunshine and change in characteristics of the road surface, and it is reported that the roof coil has a reliability of 99% or more in the actual environment. Because it is. The roof vehicle detecting apparatus detects a change in inductance generated in the roof coil by the movement of the vehicle, and detects traffic information such as the presence or absence of the vehicle, the traveling speed of the vehicle, and the type of the vehicle.

1 is an installation configuration diagram of a conventional roof vehicle detecting device. As shown, after cutting the road to the desired lane or place to detect the roof coil (1) and the incoming line (3) for connecting to the roof detection device, the roof detection device (5) and the vehicle detection information It consists of a controller 6 for utilization.

2 shows the installation form of a conventional conventional roof coil. Kinds of octagonal roof coil 25, 32 angular roof coil 26 and circular roof coil 27 are used, and the size of octagonal roof coil 25 is 1.8M * 1.8M, 32 angular. The size of the roof coil 26 is 4.0M * 1.8M, the size of the circular roof coil 27 is 1.8M in diameter.
