Such an image file name and a GPS file name may shorten the time and location search time for the image stored in the black box 100.

In an embodiment, a Global Positioning System (GPS) file having the same file name as an image file having time information may include GPS information for a time period corresponding to the image file in text format. In an embodiment, a target image file may be identified using the file name of the GPS file and GPS information inside the GPS file.

9 is a diagram illustrating an exemplary image file name and a GSP file name stored in the black box 100 according to an embodiment of the present invention in a shaded area. 9, when a vehicle enters a shaded area such as an underground parking lot while driving, the black box 100 cannot receive GPS information, so the latest GPS information received before entering the underground parking lot is copied and It can be recorded in a GPS file that matches the recorded video file. That is, the GPS information of an image recorded in the shadow area may record all recent GPS information immediately before the shadow area.

In an embodiment, GPS information is generated at predetermined time intervals, and GPS information in a shaded area in which GPS information is not generated may be stored at predetermined time intervals by following previously generated GPS information.

10 is a diagram illustrating a method of determining user location information in a user terminal 200 according to an embodiment of the present invention. Referring to FIG. 10, the user terminal 200 may record a current location at predetermined intervals (eg, 10 minutes).

In an embodiment, the user location information may be 2-point location information corresponding to the user terminal 200. Whether to feedback the report request notification message may be determined in consideration of whether or not overlap between the first area corresponding to the 2-point location information and the second area corresponding to the report request notification message.

In an embodiment, the 2-point location information may include initial location information and current location information of a point outside the driver's moving range.

The user terminal 200 may record locations in a manner that does not record all locations in units of 10 minutes, but maintains only two pieces of location information (squares) of the outermost point of the moving range. As a result, the user terminal 200 can only store a range in which the driver of the vehicle has approximately moved. Meanwhile, it should be understood that the time interval for storing the user location information in the user terminal 200 is not limited to 10 minutes.

FIG. 11 is a diagram illustrating two-point location information stored in a user terminal according to a movement path shown in FIG. 10 by way of example. At time (a), the user terminal 200 may store (x, y) location information. In time (a+10 minutes), the user terminal 200 may store (x, y) and (x1, y1) location information. At time (a+20 minutes), the user terminal 200 deletes the location information of (x1, y1) because the value of x2 is not between x and x1, and the value of y2 is not between y and y1, (x2, y2) information can be stored. At time (a+30 minutes), the user terminal 200 deletes the location information of (x3, y3) because the value of x3 is between x and x3, and the value of y3 is between y and y2, and ( x2, y2) information can be maintained as it is.

In another embodiment, the user terminal 200 may enlarge the square range by using the stored 2-point location information as a predetermined error value (a). For example, at a time (a+30 minutes), the user terminal 200 may store location information of (x-a, y-a) and (x2+a, y2+a).

12 is a diagram illustrating a main screen of a reporting app installed in a user terminal 200 according to an embodiment of the present invention. As shown in FIG. 12, the reporting app may include a server setting function menu and a black box SSID setting menu.

13 is a diagram illustrating a screen for setting video collection time and location information in the server 400 according to an embodiment of the present invention. The server 400 may request the user terminal 200 to set the reporting range. As shown in FIG. 13, the report request type may be selected as 1 (jurisdiction), 2 (competent police office), and 3 (nationwide).

If the report request type is '1', the report app of the user terminal 200 compares the set server code (eg, PL0900 (Sejong Police Station)) with the server identifier (PL0900) sent from the server 400 and is the same, You can receive a report request notification message. On the other hand, the report app can ignore the report request notification message when the set server code and the server identifier do not match.

If the report request type is '2', the report app of the user terminal 200 is the first two digits (eg,'PL') of the set server code and the first two digits of the server identifier transmitted from the server (eg,'PL'). When') matches, a report request notification message can be received. On the other hand, the report app can ignore the report request notification message when the first two digits of the set server code and the first two digits of the server identifier do not match.

If the report request type is '3', the report app of the user terminal 200 may unconditionally receive a report request notification message.

As described above, the report request type may include a value indicating whether to provide feedback on the report request notification message.

On the other hand, the reporting app of the user terminal 200 may determine whether or not to provide feedback request notification by checking the location range of the driver. For example, the report app is a report request notification when the driver location information (x, y), (x2, y2) range shown in FIGS. 10 and 11 and the report location information transmitted from the server 400 overlap at least in part. You can receive messages. On the other hand, the report app can ignore the report request notification message if the driver's location information and the report location information do not overlap.

On the other hand, the reporting app of the user terminal 200 may include a function of automatically connecting the black box 100 and WiFi when detecting a set SSID (Smoking Gun), even if the user does not directly connect. This can eliminate the hassle of having to connect by selecting a black box SSID by the user.
