Parking management system using the visible light wireless communication

The present invention relates to a parking management system of a vehicle, and more particularly, to transmit location information of a user's vehicle parked to a server by visible light wireless communication between the LED lighting apparatus provided in the automobile and the LED lighting apparatus installed in the parking lot. The server stores the location information of the car parked, and when the user requests the parking location information of the car using a mobile communication terminal such as a mobile phone, the server delivers the location information of the user's car parked to the user's mobile communication terminal. The present invention relates to a car parking management system using visible light wireless communication.

Recently, a communication method called a visible light wireless communication method has been proposed.

The visible light wireless communication method is a communication technology for transmitting information using visible light, which is an area of light visible to the human eye, and is mainly visible light emitted by a device having a light emitting diode (LED) such as a lighting device or a display device. Use

That is, when a communication signal for wireless communication transmits a given data signal to the LED driving driver digitally, and the LED driving driver drives the LED lighting device by the received data signal, the LED lighting device is modulated according to the data signal. A method of performing wireless communication with each other by emitting LED light having intensity and demodulating a communication signal by receiving the LED light having the intensity of modulated light through a photodiode such as a photodiode in a receiver.

In this case, since the LED driver drives the LED lighting device through a high speed switching signal, the human eye recognizes that the LED lighting device is continuously turned on without recognizing that the LED lighting device is blinking.

In particular, since the visible light wireless communication method uses light itself as a signal transmission medium, interference with the existing radio frequency does not exist, and thus, the visible light wireless communication method is applied to communication between devices using LED lighting.

The present invention provides a configuration of a parking management system using visible light wireless communication to easily determine the location where the vehicle is parked by using the visible light wireless communication system described above.

The configuration of the parking management system using the visible light wireless communication of the present invention for achieving the technical problem as described above, the user's car is parked by the visible light wireless communication between the LED lighting equipment provided in the car and the LED lighting equipment installed in the parking lot Delivers the location information to the server, and the server stores the location information where the car is parked. When the user requests the parking location information of the car using a mobile communication terminal such as a mobile phone, the server sends the user's car to the user's mobile terminal. It is characterized by passing the parked location information.

Parking management system using the visible light wireless communication of the present invention having the configuration as described above, the user does not need to memorize each place where his car is parked, there is an effect that the convenience of parking is improved.

In addition, not only utilize the existing LED lighting equipment of the parking lot, but also change the driving driver of the LED lighting equipment and only need to install the receiving module, there is an advantage that it is possible to install the parking management system at a relatively low cost.
