In one case of this embodiment, the case of a failure occurring at the video capture end is as follows: the video acquisition end is shielded, so that the uploaded video is a black screen; the video acquisition end is passively cut off and cannot upload videos. Therefore, when the working state of the video acquisition end fails, extracting the video data acquired within a period of time before the video acquisition end fails specifically comprises:
step S110: when the video uploaded by the video acquisition end is a continuous full-black video, video data uploaded by the video acquisition end in a specified time period before the full-black video appears is intercepted.
Step S111: when the video acquisition end interrupts the uploading of the video, the video data uploaded by the video acquisition end before the uploading of the video data is interrupted is intercepted. The video data are analyzed to find out the fault reason with the highest possibility, so that the video data provide guidance directions and reference opinions for maintenance personnel, the time for problem finding is shortened, and the root cause of the problem is found quickly.

Step S31: and identifying the change condition of the video definition and brightness in the last appointed time period in the video data.
Step S32: when the video definition and the brightness gradually become dark and disappear, the reason for interrupting uploading the video data by the video acquisition terminal is judged in advance to be battery power exhaustion. Because the electric quantity is gradually exhausted, the electric quantity cannot support the normal operation of the video acquisition end, and the picture gradually blurs and disappears.
Step S33: when the video definition and the brightness are suddenly darkened, the service time of the video acquisition end is further obtained, and whether the service time is in the aging life interval of the equipment is judged.
Step S34: when the service life of the video acquisition end is in the aging life interval of the equipment, the reason that the video acquisition end interrupts uploading of the video data is judged in advance to be natural aging damage of the video acquisition end. The probability of equipment failure is increased after the aging life interval of the equipment is used for a certain time, and the video acquisition end can lose pictures due to slight external stimulation.
