A time (Tbef + Taft seconds) obtained by adding the recording time Taft seconds after receiving the recording command signal to the recording time Tbef seconds before receiving the recording command signal is recorded on the CF card 10 when the recording command signal is received. This corresponds to the total time Tsum of the information recording range. The recording time Tbef before receiving the recording command signal can be set in the range of 5 seconds to 25 seconds, and the recording time Taft after receiving the recording command signal can be set in the range of 5 seconds to 25 seconds. Is possible.

  In the present embodiment, the image information, the vehicle position information, the time information, and the vehicle information stored in the second recorder SD-RAM 46 over a predetermined period determined based on the reception time Rs of the recording command signal as described above are stored in the CF. Although it is configured to record on the card 10, it is not limited to such a configuration.

  FIG. 9 is a diagram showing a relationship between the G sensor output value exceeding the threshold and the total time Tsum of the recording range of the image information recorded on the CF card 10. The center device 4 determines that the G sensor output value, which is information transmitted from the vehicle allocation device 2 and is acceleration information representing the gravitational acceleration of the vehicle detected by the G sensor 14, exceeds the threshold value Gmax or Gmin. Then, a record command signal that causes the CF card 10 to record at least part of the image information, vehicle information, and position information when the G sensor output value exceeds the threshold value Gmax or Gmin is transmitted to the vehicle allocation device 2. The threshold value Gmax in the present embodiment is 0.4G, and the threshold value Gmin is minus (−) 0.4G.

  When the recorder CPU 41 receives the recording command signal via the vehicle allocation device 2, the recorder CPU 41 temporarily stores it in the second recorder SD-RAM 46 over a recording range of up to 30 seconds with reference to the threshold excess time Tg of the G sensor output value.

Therefore, it is possible to reliably detect not only a longitudinal collision accident but also a lateral collision accident and analyze the cause. In the present embodiment, the vector sum of the gravitational acceleration in the front-rear direction and the gravitational acceleration in the left-right direction is obtained, and it is determined whether or not the obtained value exceeds the threshold value Gabs. This threshold value Gabs can be changed to an arbitrary value by setting.

The information temporarily stored in the second recorder SD-RAM 46 is recorded on the CF card 10 from the time TR2 at which the Lo signal for switching to the state is output to the time when Taft 2 seconds elapses. However, it is not necessarily limited to such a configuration.

  In another embodiment of the present invention, the recording is temporarily recorded in the SD-RAM 46 for the second recorder over a recording range of up to 30 seconds on the basis of the time TR1 at which the Hi signal for switching from the empty vehicle state to the actual vehicle state is output.

  The time obtained by adding the recording time Taft 1 second after the time TR1 to the recording time Tbef 1 second before the time TR1 is recorded on the CF card 10 when the Hi signal for switching from the empty state to the actual vehicle state is output. This corresponds to a total time T1 seconds of the information recording range. A maximum of 30 seconds can be set within a range from 5 seconds to 25 seconds before the time TR1 has elapsed and from 5 seconds to 25 seconds after the time TR1 has elapsed.

  Also, image information and G sensor output values temporarily recorded in the second recorder SD-RAM 46 over a recording range of up to 30 seconds with reference to the time TR2 at which the Lo signal for switching from the actual vehicle state to the empty vehicle state is output.
