Lastly, the server 300 is installed at a specific place such as a garage of the vehicle, requests the event item through the wireless communication network to the vehicle DVR apparatus 200, and stores the received event item by database in a list. . Therefore, the manager can make management much easier because only the data of the vehicle in which the event occurs are collected without looking at the data stored in the DVR devices of all the vehicles.

The vehicular DVR device 200 having the above-described configuration stores the speed in the video data while recording a video of how many kilometers the vehicle currently runs. When the vehicle speeds up, stops suddenly, starts or runs, an event item for a violation is generated and an event item (violation data) is stored together with the speed when the video is stored in the digital video / audio memory 205. ) Is also stored together.

Then, the in-vehicle DVR device 200 manages an event item (violation material) separately so that an administrator can conveniently manage it later. In other words, make a list for each violation and save it or make a list for each time. The data generated in this way is displayed as a list, and when the list of the selected item is selected, the corresponding item is searched and the video data is displayed on the monitor screen.

If a collision accident or a safety accident occurs in a vehicle while driving, pressing the emergency button stores the current date and time in the event item. Previously, when an accident occurred, the driver wrote down the date and time of the accident on paper one by one. If the driver could not record the date and time because there was no situation, there was a problem of finding the stored video data one by one. However, using the emergency button 214 function implemented in the present invention can easily solve this problem.

When the vehicle arrives at the point where the server 300 is installed, the event item stored in the memory unit 206 is transmitted to the server 300 through the wireless module 212 to the wireless communication network.

The server 300 displays a database on a monitor screen by making a database for easy management. The manager can easily manage the data by collecting only the data of the vehicle in which the event occurs, without having to collect and view all the vehicle data.

3 is a display example of an event item according to a preferred embodiment of the present invention.

As shown in Fig. 3, the event items include year, month, day, hour, violation items (speeding, opening run, sudden start, sudden stop, accident, etc.).

As such, when the emergency button 214 is attached to the vehicle DVR device 200 and configured, if an accident such as a safety accident or a crash occurs in the vehicle, the driver presses the emergency button 214 to be stored in an event item. You can save this time separately to facilitate future searches.

In the past, when an accident occurs, the driver writes the date and time on paper. In this case, if the driver is embarrassed and does not write it down accidentally, there is a lot of inconvenience in handling the accident later. In order to eliminate such inconvenience, when an accident occurs by attaching a separate button, the driver directly presses the emergency button 214, which is convenient because the accident date and time are simply recorded.
