At this time, the reset of the smartphone 101 can be made at least twice, and if the camera 104 does not normally photograph the parking surface even after the second reset, the smartphone parking guidance camera 100 equipped with the camera 104 ) By sending a message including the unique number and location information of the manager to the manager's terminal so that the smartphone parking guidance camera 100 is repaired by the manager, the detection of the parking surface using the camera 104 is normally performed.

The configuration of the parking guidance control server 500 may be omitted when the video and photo data of the parking surface taken by the camera 104 in the smartphone parking guidance camera 100 is analyzed through the microcomputer 108, and this In this case, the smartphone parking guidance camera 100 converts the analysis result data into a control signal in the microcomputer 108 so that the Mangong differential light 111, the wired Mangong differential light 113, and/or the Bluetooth Mangong differential light 200 turn on or flicker. do.

The image storage server 600 stores the image and photo data of the parking surface received from the smart phone parking guidance camera 100 in a database. At this time, the administrator can connect to the server 600 for image storage and upload the image and photo data of the parking surface stored in the database to a terminal or PC program.

The cloud server 700 may be configured when the smartphone parking guidance camera 100 analyzes the parking surface video and photo data, and the parking surface video and photo data and analysis from the smartphone parking guidance camera 100 Receive and store result data.

At this time, each smartphone parking guidance camera 100 receives (uploads) the video and photo data of the parking surface stored in the cloud server 700, whether the vehicle is parked and the analysis result data of the license plate of the vehicle to the parking surface. It can induce parking of approaching vehicles.

In this way, when the smartphone parking guidance camera 100 analyzes the video and photo data of the parking surface and the cloud server 700 is configured, the configuration of the expensive and high-performance parking guidance control server 500 can be omitted, The cloud server 700 has an effect of improving the problem of the parking guidance control server 500, which is difficult to perform its role when communication is disconnected due to an internet problem.

The management web server 800 is a smart phone parking guidance camera 100 and the Bluetooth emergency bell 300 and / or Bluetooth emergency button 400 installed in the parking lot are wirelessly connected without a pairing process. ) And pairing information between the Bluetooth emergency bell 300 and/or the Bluetooth emergency button 400 is stored in the database.

Hereinafter, a parking guidance process by detecting a parking surface using an emergency situation management system according to an embodiment of the present invention will be described in detail.

6 is a diagram for explaining a parking induction process using an emergency situation management system according to an embodiment of the present invention.

Referring to FIG. 6 , a plurality of parking areas 10 may be formed in a parking lot. For example, a first parking area 10a, a second parking area 10b, a third parking area 10c, and a fourth parking area 10a. A parking area 10d may be formed.

Each of the plurality of parking areas 10a, 10b, 10c, and 10d includes a parking surface 11 in which the vehicle is in an empty state and a parking surface 12 in which the vehicle is in a full state, and each parking surface 11 and 12 includes At least one of a mangong differential 111, an external wired mangong differential 113, and a Bluetooth mangong differential 200 is disposed.

A plurality of smartphone parking guidance cameras 100 are provided to detect the parking surfaces 11 and 12 of the plurality of parking areas 10a, 10b, 10c, and 10d, and for example, the first smartphone parking guidance camera ( 100a), the second smartphone parking guidance camera (100b), the third smartphone parking guidance camera (100c) and the fourth smartphone parking guidance camera (100d) can be configured.

A plurality of smartphone parking guidance cameras (100a, 100b, 100c, 100d) can detect three or more parking surfaces (11, 12) formed in each parking area (10a, 10b, 10c, 10d) according to the specifications of the wide-angle lens. can

For example, the first smartphone parking guidance camera 100a is disposed in the first parking area 10a, and photographs the second parking area 10b facing the first parking area 10a with the camera 104. The three parking surfaces 11 and 12 formed in the second parking area 10b can be detected. Unlike this, the second smart phone parking guidance camera 100b disposed in the second parking area 10b takes pictures of the first parking area 10b with a camera 104, and displays three images formed in the first parking area 10b. Parking surfaces 11 and 12 can be detected.

That is, the smartphone parking guidance camera 100 of the present invention can detect the parking surface of the facing position based on the installed position.

On the other hand, a plurality of smart phone parking guidance cameras (100a, 100b, 100c, 100d) can guide the vehicle to be parked in the parking surface 11 of the empty state formed in each parking area (10a, 10b, 10c, 10d) .

For example, when the vehicle is parked on the parking surface 12 of the first parking area 10a to which the first parking guidance camera 100a is to guide parking and is in a full state, the first parking guidance camera 100a is the microcomputer 108 ) is transmitted to the mangong differential control unit 110 so that the mangong differential lamp 111a turns on or flickers in red light, so that the vehicle is parked on the parking surface 12. Drivers of other vehicles can be informed of the state there is. Furthermore, the first parking guidance camera 100a causes the wired mangong differential lights 113a and 113b to turn on or blink in green light through the mangong differential lamp external connector 112, so that the driver of another vehicle can see the empty vehicle where the vehicle is not parked. The vehicle may be induced to be parked on the other parking surface 11 of the first parking area 10a in this state.

As another example, when the parking surface 11 of the third parking area 10c to which the third parking guidance camera 100c is to guide parking is in an empty vehicle state, the third parking guidance camera 100c controls the microcomputer 108. A signal may be transmitted to the mangong differential control unit 110 so that the mangong differential lamp 111c turns on or flickers in green light, thereby inducing the vehicle to be parked on the parking surface 11. Furthermore, the third parking guidance camera 100c controls the operation of the Bluetooth mangong differential light 200a wirelessly connected through Bluetooth 103 to induce parking of the vehicle on a parking surface in a location where wired connection is difficult to reach the corresponding parking surface. The vehicle can be induced to park.
