The tag identification information is used to confirm that the data transmitted to the third Zigbee device 640 is the data requested by the third Zigbee device 640, and the remaining information may be configured as guide information as illustrated in FIG.

The parking assistant can input a selection command by operating the button unit 660. The I / F circuit 630 converts a key input signal of the button unit 660 into an interrupt signal and outputs the interrupt signal to the third Zigbee unit 640, .

For example, when the parking person presses the "parking confirmation" button, the third Zigbee device 640 confirms the parking status information matched with the coordinate information, grasps the current position of the parking person who left the vehicle through the first Zigbee device 100 do.

The third Zigbee device 640 confirms the parking status information on the coordinate information, and generates the guidance information.

As the parking person carrying the tag 600 moves, the third Zigbee device 640 grasps the current position in real time through the first Zigbee device 100, and sequentially generates the guide information through the screen display part 650 Is displayed.

The "parking" button illustrated in Fig. 11 is a button for searching for a parking available area, and the "parking information" button is for checking parking time information, parking payment information and the like.

In addition, the user can control the power supply of the tag 600 by directly pressing the "on / off" button without depending on the mode selection operation by the third sensor 650. [
