Among them, a method of storing an image photographed using a camera or the like uses a method of storing an image photographed by a camera mounted on a vehicle in which an accident occurs. However, using such a conventional method, it is possible to determine whether an accident has occurred by analyzing the captured image, but it is insufficient to determine the degree of negligence of the perpetrator and the victim.

This is because, when an accident occurs outside the shooting area, for example, when a collision accident occurs in the rear of a vehicle equipped with a black box for a vehicle that photographs only the front, objective evidence of the accident cannot be obtained.

Therefore, in order to secure objective evidence in the event of an accident of a vehicle, a technology capable of securing an image of an accident scene of the vehicle is required.

In order to solve this problem, Korean Patent Publication No. 10-2011-0088012 discloses a "vehicle accident image data collection device" that enables the collection of image data of an accident scene of a vehicle from nearby vehicles when an accident occurs. Is disclosed. When the accident image data collection device of the vehicle determines that an accident of the vehicle has occurred, an accident image data request message requesting the surrounding vehicles to transmit the accident image data generated by photographing the vehicle at the time of the accident of the vehicle It generates and sends to the surrounding vehicles, and receives the response message of the surrounding vehicle to the accident image data request message. However, in the above-described prior art, the accident image data request message should be transmitted to the surrounding vehicles at the time of the accident.

In addition, as another background technology, Korean Unexamined Patent Publication No. 10-2011-0012120 discloses a black box service system. Referring to FIG. 1, the black box service system includes a black box 101, a black box service server 103, a related department 105, a wireless terminal 107, and a CCTV video service server 109. The black box service server 103 stores the location information and the image information transmitted from the black box 101 and transmits the transmitted location information and the image information to the related department 105. The preset department 105 may be a fire department, a police station, or an insurance company of a user of the black box 101 related to traffic accident processing. Therefore, the police station or insurance company can recognize the occurrence of the traffic accident by using the location information and the image information transmitted from the black box service server 103, can be dispatched to the accident site quickly to handle the accident.

However, this technology, when the impact on the black box over the threshold set by the traffic accident, the shock sensor detects the shock, the black box service server stores the location information and video information transmitted from the black box, and transmits It is configured to transmit the location information and the image information, and there is no supplementary means for the malfunction of the shock sensor due to the road situation or other external conditions, and also to receive the request information from the wireless terminal, the CCTV video service server Since it is configured to transmit the CCTV image information received from the wireless terminal, there is a disadvantage that the transmission of the accident image is not made when the user is unconscious due to the accident.
