Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily carry out the technical idea of the present invention.

1 is a block diagram illustrating an automatic parking guide system according to an embodiment of the inventive concept.

Referring to FIG. 1, the automatic parking guide system includes a plurality of parking detection sensors 110, a plurality of movement detection sensors 120, a central control device 130, a plurality of parking guide devices 140, and a plurality of location tracking devices. And 150.

The parking sensor 110 is installed in each parking space to check whether the vehicle is parked in each parking space. In this case, the parking space means a space divided so that one vehicle can park. The parking sensor 110 may be implemented using an electromagnetic field sensor, a distance measuring sensor using an ultrasonic wave, or an infrared sensor. In addition, the parking sensor 110 may be implemented through a CCTV camera or an image sensor equipped with a vehicle recognition function.

The movement detection sensor 120 is installed at an intersection in the parking lot, and detects whether the vehicle enters or exits in each direction of the intersection. The movement detection sensor 110 may be implemented using an electromagnetic field sensor, a distance measuring sensor using an ultrasonic wave, or an infrared sensor. In addition, the movement detection sensor 120 may be spherical through a CCTV camera or an image sensor equipped with a vehicle recognition function.

The central control unit 130 receives data from the parking sensor 110 and the movement sensor 120. The central control unit 130 controls the parking guide device 140 based on the data received from the parking sensor 110 and the movement sensor 120.

In detail, the central control unit 130 receives data from the parking sensor 110 and grasps the number of available parking vehicles in each parking section. Here, the parking section means a space divided by the vehicle moving road in the parking lot. For example, the parking compartment includes a plurality of parking spaces and may be divided by numbers or alphabets.

In addition, the central control unit 130 receives data from the movement detecting sensor 120 to determine the number of vehicles entering or exiting each direction of the intersection. This is to prevent the number of vehicles guided to a particular parking section from being larger than the number of vehicles available for parking.

In detail, the number of vehicles guided to a particular parking compartment should not exceed the number of available parking spaces in that parking compartment. If a small number of vehicles are guided to a parking compartment in which one parking space is present, the first induced vehicle can park, but the later induced vehicle cannot find a parking space.

Therefore, in an embodiment according to the technical idea of the present invention, the central control unit 130 receives data from the movement sensor 120 and grasps the number of vehicles entering or exiting each parking compartment in real time.

That is, the central control unit 130 is based on the number of vehicles parked in each parking compartment received from the parking detection sensor 110 and the number of vehicles entering or exiting each parking compartment received from the movement detection sensor 120. As such, the parking guide device 140 is controlled in real time so that the number of vehicles guided to the specific parking compartment does not exceed the available parking space of the corresponding parking compartment.

The parking guide device 140 guides the vehicle to be parked to the parkable section in response to the control of the central controller 130. For example, the parking guide device 140 may be installed at each intersection in the parking lot to guide the vehicle to be parked into the parking available section. Parking guide device 140 may be implemented in the form of a traffic light, it may be implemented by installing a light on the road. In addition, the parking guide device 140 may be implemented as a traffic light, LED sign. In addition, the parking guide device 140 may be configured to include a movement sensor 140 therein.

The location tracking device 150 checks in which parking section the vehicle is parked. The location tracking device 150 may be provided inside the vehicle or provided as a portable wireless device at the entrance of the parking lot. For example, the location tracking device 150 periodically communicates with the central control device 130 to determine in which parking section the vehicle is parked. As another example, the location tracking device 150 may communicate with the wireless transceiver installed at the intersection each time it passes the intersection to determine which parking section the vehicle is directed to. In this case, the movement detecting sensor 120 installed at the intersection may exchange data with the vehicle when the movement of the vehicle is detected.

Meanwhile, in an embodiment according to the technical idea of the present disclosure, the parking sensor 110, the movement sensor 120, the central control unit 130, and the parking guide device 140 may be connected through a wired network. . For example, if the parking available area is identified through the vision recognition of the CCTV camera, a wired network for image transmission may be used.

In addition, the parking sensor 110, the movement sensor 120, the central control unit 130, and the parking guide device 140 may configure a wireless sensor network. In this case, the Zigbee-based radio transceiver may be used as the radio transceiver.

FIG. 2 shows an embodiment of parking guidance by the parking guide system of FIG. 1.

For simplicity, it is assumed that the parking lot includes six parking compartments 10 separated by alphabets, each parking compartment 10 having ten parking compartments 20. In addition, it is assumed that the parking guide device 150 and the movement detection sensor 120 are installed at each intersection of the parking lot. In addition, it is assumed that the parking detection sensor 110 is installed in each parking space 20.

2, the vehicle 1 enters the entrance of the parking lot and reaches the first intersection. In this case, there is no parking space in the A and D parking compartments. Accordingly, the parking guide device 150 in the A and D directions will be off and the parking guide device 150 in the B and C directions will be on.

When the vehicle 1 moves in directions B and C according to the guidance of the parking guide device 150, the movement detection sensor 120 detects the movement of the vehicle and transmits the movement to the central control device 130. The central processing unit 120 will include the vehicle 1 that is currently inducing parking, and set the number of parking available in the B and C directions.

Subsequently, the vehicle 1 reaches the next intersection in accordance with the guidance of the parking guide device 150. In this case, there are parking spaces in the B and E parking compartments. Thus, the parking guide device 150 in the B and E directions will be on. In addition, the parking compartment in the C direction (C and D parking compartment) has a parking space. Accordingly, the parking guide device 150 in the C direction will also be turned on. In this case, the driver can park in a desired direction by driving, and in the embodiment of the present invention, it is assumed that the vehicle 1 is parked in the B parking section.

In this case, the central control unit 130 will reset the number of parking-capable vehicles in the parking lot B based on the data transmitted from the movement sensor 120 and the parking sensor 110.

On the other hand, the vehicle 2 can also be parked in the F parking compartment in the same manner as described above. However, when the vehicle 2 moves to the parking lot F, the movement detection sensor 120 detects this and transmits it to the central processing unit 130. The central processing unit 130 controls the parking guide device 150 to turn off the parking guide device 150 in the direction of the F parking section. Thus, no further vehicles will be guided to the F parking compartment.

On the other hand, in an embodiment according to the technical idea of the present invention, the central control unit 130 may control the parking guide device 150 to guide the vehicle to be parked to the parkable parking section existing at the shortest distance. For example, the central control unit 130 may drive the vehicle 2 into the B or E parking section by turning off the parking guide device 150 in the C and F parking section directions.

In the detailed description of the present invention, specific embodiments have been described, but it is obvious that various modifications can be made without departing from the scope and spirit of the present invention. Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined by the claims equivalent to the claims of the present invention as well as the claims of the following.
