Due to the increase in the number of vehicles these days, many people are driving their cars to their destinations, and it is often necessary to park the vehicle in a stable parking lot until the work is completed. Therefore, in places such as a department store, a government office, a large building, or a parking lot where a lot of vehicles are in and out, a parking lot is collected and the vehicle is controlled only to enter and exit.

That is, when the driver enters the vehicle through the entrance of the vehicle and takes a ticket for the collection of the fare, the breaker is opened to allow the vehicle to enter the inside. When the vehicle is parked at the exit, After the fare is paid, the breaker must be opened so that it can escape to the outside of the parking lot of the vehicle.

However, in the above-described conventional parking management system, it takes a lot of time to find and park an empty parking space by itself while the vehicle has entered the inside of the parking lot.

However, there is a limitation in confirming the empty space even in the case of using such guidance personnel, and there is a problem that excessive manpower and cost are required.

Accordingly, in recent years, means for automatically displaying parking or guidance have been applied. For example, a method of displaying the number of vehicles capable of entering and leaving a predetermined block or a floor and displaying the total number of parking spaces integrally is applied. This method is also inaccurate, and as in the conventional case, .

In addition, a method of lighting an indicator lamp so as to detect whether a vehicle is entering the parking space and to confirm it from a distance is attempted. Even in such a case, there is a limit to finding an accurate parking space.

On the other hand, a parking space in which a plurality of vehicles can be parked is divided into a predetermined line, and there is a problem that accurate parking is difficult due to a narrow space. In particular, when one vehicle is parked obliquely or excessively adjacent to the line, the rest of the vehicles also have a problem of parking in a precisely inaccurate position. This is because the parking line is marked on the floor, which is why the driver is unable to locate the correct line when parking.

Also, in step S130, the parking guide display unit is controlled to display the moving route. If the parking is completed in step S140, the parking information is updated in step S150, and then the guidance of the parking guide display is ended through step S160.

Hereinafter, operations and effects of the present invention will be described with reference to the drawings.

5 is a block diagram illustrating an operation of a parking guidance system according to an embodiment of the present invention.

As shown in the figure, the user turns on the headlight while activating the visible light transmitting / receiving unit 111 capable of transmitting information of the vehicle while moving the vehicle into the parking lot. When the visible light transmitting / receiving unit is activated as described above, the vehicle detection sensor 110 receives the information of the vehicle entering the parking lot and transmits the information to the central control server 140.

Meanwhile, the central control server 140 receiving the vehicle information receives the unoccupied parking position from the parking sensor 120 and moves the parking guide display unit 130 to move the vehicle to the unoccupied parking space .

Under the control of the central control server, the parking guide display unit 130 displays a moving path by a triangle or an arrow to guide the vehicle to a non-occupied parking surface. For example, the parking guide display unit displays the vehicle straight ahead, left turn, right turn, and the like until the vehicle reaches the unoccupied parking surface. For example, as shown in the figure, in the case of a route from the entrance to the target parking surface, a route of straight ahead, left turn, right turn, and left turn is displayed on the parking guide display portion at each intersection. That is, the first parking guide display unit 130a at the first intersection where the first intersection at the entrance meets an indication to go straight ahead, and the second parking guide display unit 130b, which is the second time when it goes straight, The third parking guide display unit 130c which is the third time when the left turn is generated according to the guide is displayed on the fourth parking guide display unit 130d which is the fourth time when the rightward display is generated and the right turn is made, A leftward direction indication is generated. At this time, the fourth parking guide display part 130d that meets for the fourth time can display the number of parking spaces that can be parked. The user can move to the desired parking space by moving the vehicle according to the guidance and viewing the parking guide display unit as described above.

When the vehicle is parked by moving to a non-occupied parking surface as described above, information indicating that the vehicle is detected and occupied by the parking surface monitoring sensor 120 is transmitted to the central control server 140. The central control server 140 having received the occupancy information of the parking face can control the parking guide display unit 130 to update the information of the newly occupied parking face and to guide another parking face to the next vehicle.

On the other hand, if the vehicle has escaped from the occupied parking space, the parking sensor detects the non-occupied parking space and transmits the information to the central control server, and the central control server updates the parking space information.

Therefore, since the parking guidance system according to the present invention receives the information of the vehicle and directly guides the vehicle to a non-occupied parking surface, it is possible for the vehicle driver to move to the parking surface without having to continuously search for the parking surface There is an advantage. In addition, since unnecessary movement of the vehicle is prevented, idling and unnecessary traveling are reduced, energy consumption is reduced, and the parking surface is guided to the correct position.
