In the method using a general IP camera, the image information of the camera is sent to the server, and the server receiving the information processes the image information to perform parking guidance and car number recognition. In this case, dozens of local cameras simultaneously transmit image information to one server, and the server must process the received image information in real time. Therefore, in order to meet the demand for transmitting and receiving the large amount of camera image data, a system is constructed by using an optical communication network having a wide transmission bandwidth, and the number of servers .

In addition, a general IP camera should be powered by a POE type (Power Over Ethernet Type). For this purpose, a high POE supply hub (HUB) should be installed and a POE hub or IP camera should be connected to the power supply It will lay cables from tens of meters to hundreds of meters.

In this way, the existing parking management system using the general IP camera is not only expensive to construct the parking management system such as IP camera, server, cable installation for video transmission and power supply, It is necessary to use optical communication network and operate a large number of servers.

In addition, the existing parking management system is delayed in data processing speed because the image information of the IP camera is transmitted to the server, and then transmitted to the vehicle guidance apparatus. When there are many images to be processed at the same time, Sometimes a crash or error occurs. In particular, the conventional parking management system has a problem in that it can not recognize the vehicle number or induce the vehicle when an accident such as power failure occurs.

FIG. 15 is a view showing a control method for the vehicle guidance system of the embodiment of the present invention, and FIG. 16 is a view showing the control method of the vehicle guidance system of the present invention on the camera module side and the management unit side.

The method for controlling the vehicle guidance system according to the present invention includes the steps of capturing a parking surface (S100), determining whether the vehicle is present (S200), generating a transmission signal (S300), transmitting a signal (S400) Step S600.

An initialization step of the vehicle guidance and parking position guidance system according to the present invention proceeds. The initialization phase begins by turning on the power supplied from the parking lot to power the system.

In the parking face photographing step S100, the corresponding parking face is photographed by a camera built in each of the smart phones 110 and 120 installed in the camera module unit 100. The optical information obtained by photographing the parking surface of the lens is converted into an electric signal by the optical information converting unit 111 of the smartphones 110 and 120 and transmitted to the CPU 112 of the smartphones 110 and 120.

The vehicle presence / absence determination step S200 is performed. The CPU 112 of the smart phones 110 and 120 determines whether or not the vehicle is parked on the corresponding parking surface from the electric signal. At this stage, the vehicle presence / absence determination module 826 of the parking induction program module 820 is used. The vehicle presence / absence determination module 826 determines whether or not the vehicle is parked on the corresponding parking surface from the electric signal, Vehicle presence / absence determination signal.

The transmission signal generating step S300 is performed. The CPU 112 of the smart phones 110 and 120 compares the vehicle presence / absence determination signal with the previous vehicle presence / absence determination signal to determine whether there is a change in the parking space. At this stage, the motion detection module 821 of the parking induction program module 820 can be used. The motion detection module 821 compares the vehicle existence determination signals and generates a transmission signal when there is a change in the parking space.

The signal transmission step (S400) proceeds. The transmission signal generated when there is a change in the parking surface is transmitted to the parking induction control unit 131 of the control unit 130 through the external interface port 113 of the smartphones 110 and 120. The transmission signal is transmitted from the wireless communication apparatuses 114 and 115 such as the CDMA module 114 or the WIFI module 115 of the smart phones 110 and 120 to the IP address sharing unit 300 and the terminal period aggregation apparatus 400, And transmitted to the management unit 500 via the network.

Occupancy display step (S500) proceeds. The parking induction control unit 131 of the control unit 130 determines whether the parking display unit 200 is occupied or not occupied and displays the parking display unit 200 in accordance with the received transmission signal.

The management unit update step (S600) proceeds. The transmission signal received by the management unit 500 may include information on a new occupancy vehicle such as a car number parked on a parking space, for example. The information stored in the management unit 500 for the parking surface and the parking vehicle included in the transmission signal is updated.

The transmission of the information is preferably transmitted from the smart phones 110 and 120 to the IP address sharing unit 300 through wireless communication. The information received at the IP address sharing unit 300 is transmitted to the terminal period aggregation apparatus 400 and then transmitted to the management unit 500 so that the management unit 500 can be updated.

Effects of the vehicle guidance system, the installation method thereof, and the control method thereof according to the present invention will be described.

In general, the parking management system using the IP camera requires a considerably high purchase price of the IP camera, except for the vehicle differential and other equipment for carrying out the vehicle guiding function.

In addition, since the power source must be supplied as POE type in the case of the IP camera, it is impossible to use the 220V power supply normally supplied to the parking lot, and POE HUB should be installed and cables should be installed from several tens meters to several hundred meters depending on the position of the camera .

The parking induction system, the installation method thereof, and the control method thereof according to the present invention can solve the high cost problem required for a general parking lot management system by using a smart phone installed in the camera module unit.

In general, smart phones have high-resolution cameras, image processing capabilities, high-performance CPUs and memories, and wireless communication devices. In addition, the used smart phone is very easy to obtain because it is active in the market, and it is very cheap compared to the IP camera.

The built-in camera of the smartphone is high-performance so that it can take high-resolution photographs and can take clear and clear images of specific parts, so it is enough to judge the existence of vehicle or car number by photographing one side of the parking lot. Therefore, it is possible to perform functions of a general IP camera with a built-in camera in an inexpensive used smart phone.

Since the smartphone can use the 220V power supply which can be easily provided around the parking lot, it is possible to solve the problem of installing POE HUB required for installation of the existing IP camera system and separately installing a cable for power supply.

However, since the parking guidance system according to the present invention requires only a wireless router to be connected to the management unit, it is possible to use a wireless Since various wireless communication functions such as CDMA, WIFI, BT (Bluetooth) can be utilized by using the communication function, construction for communication is unnecessary.

The parking guidance system according to the present invention not only can save a great deal of cost in installation, but is also effective in controlling the system.

In the existing parking management system, the IP camera is only used for shooting the parking area. However, the IP camera can not proceed with the parking induction and number recognition. Therefore, it sends the image information of the camera to the server, And then control the system by sending commands to individual systems, such as a pseudo-differential. As a result, image information captured by dozens of cameras is simultaneously transmitted to a server, so a high-performance server must be provided, and a large number of NVR (Network Video Recorder) servers for processing a vehicle guidance and car number recognition process are secured There is a problem to be done.

In the case of the parking induction system according to the present invention, parking guidance and car number recognition can be handled using the self CPU 112 and the memory of the smart phone. That is, the parking induction program module 820 and the car number analysis program module 830 can perform the parking guidance and the car number recognition function in the camera module unit 100 in which the smartphone is installed.

Since only a small amount of data such as the presence of a vehicle and a car number can be transmitted to the management unit 500 in order to guide the entire parking lot by the zone-specific guide unit 600 and the comprehensive guide unit 700, Do.

In addition, it is possible to utilize the memory built in the smartphone to store the parking image, and it can be extended to a separate external memory which is very inexpensive as NVR (Network Video Recorder) server. The video data can be stored in the server of the management unit 500 by transmitting the video data to the management unit 500 at a time when the communication cost is low such as the morning time zone.

Since the terminal period aggregation apparatus 400 can sequentially transmit the image data stored in the smart phones 110 and 120 to the server of the management unit 500 by the first switching hub 410 and the second switching hub 420, The load can be minimized and the system construction cost can be minimized because the amount of data requiring simultaneous processing is small.

The parking induction system according to the embodiment of the present invention can be automatically switched to the rechargeable battery provided in the smart phone, so that the system can be operated stably for a long time even in the case of a power failure. In addition, there is an advantage that the parking display unit 200 can be operated without an emergency power source by using a lighting function built in a smartphone even during a power failure.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And it goes without saying that the invention belongs to the scope of the invention.
