Therefore, how to change the current panoramic vehicle data recorder when the vehicle is in a flameout state, the panoramic vehicle data recorder works for a long time, so that the power supply is insufficient, and the problem that needs to be solved by users are needed at present. The low-power protection method of the automobile data recorder provided by the embodiment of the application is applied to a server. The server of the present application may be a platform for providing services for a vehicle event data recorder on a vehicle, and fig. 1 is a first flow chart of a low-voltage protection method of a vehicle event data recorder according to an embodiment of the present application, and referring to fig. 1, the method includes the following steps S101 to S105.

S101: and acquiring information that the cameras are in a dormant state.

In S101, the plurality of cameras refer to the number of driving recorders in the vehicle, and the present application is mainly directed to a panoramic driving recorder, which is a vehicle-mounted image capturing device with a wide angle or a panoramic view, and is used for recording video and sound during driving of the vehicle, and the panoramic driving recorder generally adopts a multi-camera system, and installs the plurality of cameras at different positions of the vehicle, such as front, rear, left, right, and other directions. Multiple cameras can shoot pictures in different directions at the same time, and the pictures are combined into a panoramic picture by using a software technology. The panoramic automobile data recorder is implemented by using a plurality of automobile data recorders.

At this time, the cameras are used in the panoramic traffic recorder, and when the vehicle is in a flameout state, the panoramic traffic recorder in the vehicle is in a dormant state, namely in a closed state, so that unnecessary electric quantity consumption is reduced.

S102: acquiring preset information of a preset vehicle in a preset range; the preset information is personnel information or vehicle information near the preset vehicle.

In S102, after determining that the preset vehicle is in a flameout state, information that the plurality of cameras are in a dormant state is obtained. The preset range is a peripheral distance extending to the periphery by N meters by taking the preset vehicle as a circle center, and can be set according to actual conditions.

In order to facilitate obtaining preset information close to a preset vehicle, a vibration sensor or a movement detection function is installed in the preset vehicle, vibration or movement around the preset vehicle can be sensed after the vibration sensor or the movement detection function is installed, and according to the vibration or movement information, a panoramic automobile data recorder is started to record. As shown in fig. 2, the method includes steps S201 to S203.

S201: acquiring movement information of a preset vehicle; the movement information is vibration information acquired by a vibration sensor in a preset vehicle, and the vibration information comprises vibration source coordinates and vibration amplitude.

In S201 above, vibration information of the preset vehicle is acquired by the vibration sensor, the vibration information including the vibration source coordinates and the vibration amplitude. The vibration source coordinates are distances between a preset vehicle and a person or a vehicle approaching the preset vehicle, and a coordinate is drawn by taking the preset vehicle as a center. The vibration amplitude refers to the frequency of motion, and if a person approaches a preset vehicle, the walking frequency of the person is obtained; when the vehicle approaches the preset vehicle, the running frequency of the vehicle is acquired. The movement detection function can be used for acquiring preset information of a preset vehicle, and the specific mode is selected for acquisition, so that the selection can be performed based on actual conditions.

S202: and judging whether the vibration source coordinate is in a preset range or not.

In the step S202, after the vibration source coordinates are obtained, whether the vibration source coordinates are within a preset range is determined; the preset range refers to a range of values of which the values of the ordinate and the abscissa are smaller than or equal to N of vehicles or persons approaching the preset vehicle, and the approaching vehicles or persons need to be recorded.

S203: when the vibration source coordinates are in a preset range, vibration information close to a preset vehicle is acquired, and the vibration information is preset information.

In S203 described above, when the vibration source coordinates are within the preset range, preset information near the preset vehicle is acquired. The vibration source coordinate obtained for the first time can be used for judging in advance, and when the vibration source coordinate obtained for the first time is not in the preset range, the vibration source coordinate at the current time is obtained, so that whether the vibration source coordinate is in the preset range is judged.

For example, movement information near a preset vehicle is acquired, when the vibration source coordinates between the person and the preset vehicle are (2, 3), the preset range may be set to (3, 3), and when both the ordinate and the abscissa are less than or equal to 3, it is determined that the vibration source coordinates are within the preset range. The setting to acquire the preset range may be set based on actual conditions, and is not limited here.

S103: sending a preset first instruction to a plurality of automobile data recorders so that the automobile data recorders collect parking videos; the first instruction is preset as a working instruction.

In S103, it is determined that within the preset range, preset information is close to the preset vehicle, and the server sends preset first instructions to the plurality of driving recorders, wherein the preset first instructions are working instructions, that is, the driving recorders start a video recording mode; after the plurality of automobile data recorders receive the preset first instruction, the plurality of automobile data recorders begin to collect parking videos around the preset automobile. Before the plurality of automobile data recorders receive a preset first instruction, the plurality of automobile data recorders are in a closed state, so that the plurality of automobile data recorders work for a long time for reducing the electric quantity, and the electric quantity is consumed too fast.

S104: identifying a first video, and judging whether the first video has preset information or not, wherein the first video is any one of a plurality of parking videos acquired by a first driving recorder; the first automobile data recorder is any one of a plurality of automobile data recorders.

In S104, before the first video is identified, the first video is acquired, and the first video is preprocessed, where the preprocessing includes video compression, video resolution adjustment, video format conversion, and image enhancement, so as to obtain the preprocessed first video. Video compression: because the video files recorded by the automobile data recorder are usually relatively large, in order to reduce the file size and facilitate storage and transmission, the video files are compressed. Common compression formats include h.264 and h.265, among others. Video resolution adjustment: the resolution of the video may be adjusted to accommodate different display devices or storage requirements. Common resolutions include 720p, 1080p, etc. Video format conversion: the video format of the tachograph may need to be converted according to different requirements. For example, the original video file is converted into a common video format, such as MP4, AVI, etc. Image enhancement: to improve the quality and visibility of video, image enhancement may be performed, including adjusting brightness, contrast, saturation, etc.

And after the driving recorders are in the working state, acquiring a first video, and identifying the first video. The first video is any one video of a plurality of parking videos recorded and collected by the first vehicle recorder, and at the moment, the plurality of parking videos refer to videos recorded by the vehicle recorder after the vehicle recorder receives a preset first instruction. Because the duration of the video recorded in the automobile data recorder is limited, the parking video is divided into a plurality of sections for recording. The first automobile data recorder is any one of a plurality of automobile data recorders.

In order to facilitate the subsequent distinction of the parking videos recorded by each automobile data recorder, a plurality of automobile data recorders can be numbered sequentially, the automobile data recorder at a first position can be defined as a first automobile data recorder, the first position can be set to any one direction among the front direction, the rear direction, the left direction and the right direction, the automobile data recorder at a second position can be defined as a second automobile data recorder, and the second position is in other directions except the first position.

In addition, after the first video is acquired, the first video is decompressed, and the video file in the automobile data recorder needs to be decompressed and converted into processable video data. And inputting the video data into a preset face detection model for matching to obtain personnel information, wherein the personnel information is preset information, and the preset face detection model is trained by a plurality of face information and personnel information. The technology involved in the construction process of the preset face detection model is only a conventional technical means adopted by those skilled in the relevant technical field, so that further description is omitted here.

The plurality of face information refers to persons associated with a preset vehicle, such as a vehicle owner, persons associated with the vehicle owner. The corresponding relation between the face information and the personnel information is established so as to confirm the personnel information close to the preset vehicle, an algorithm and feature extraction of the model are provided, the matching is carried out in the preset face detection model, the face information of the personnel is matched and identified, and the face information obtained through the matching is compared with the preset personnel information, so that the corresponding personnel information is obtained. The preset face detection model provided by the application can also be used for confirming the personnel identity of the video and identifying target personnel.

S105: if the preset information exists in the first video, a preset second instruction is sent to the second automobile data recorder so that the second automobile data recorder enters a dormant state, the second automobile data recorder is an automobile data recorder except the first automobile data recorder among the automobile data recorders, and the preset second instruction is a dormant instruction.

In S101, it is determined whether preset information exists in the first video, and when preset information exists in the first video, it is confirmed that a preset second instruction is sent to the second vehicle event data recorder, the preset second instruction is a sleep instruction, that is, the second vehicle event data recorder is in a non-working state, and the second vehicle event data recorder is other vehicle event data recorders except the first vehicle event data recorder among the multiple vehicle event data recorders. At this time, the first driving recorder continues to work, that is, continues to record preset information, so that other driving recorders are turned off, so as to reduce the problem of insufficient power caused by long-time work of a plurality of driving recorders.

For example, four driving recorders exist in the preset vehicle, one camera exists in each driving recorder, when the first driving recorder is installed in the left direction of the preset vehicle, the second driving recorder is installed in the front direction, the rear direction and the right direction of the preset vehicle respectively, and when personnel information exists in the first video, the first video is a parking video collected by the first driving recorder. And sending a dormancy instruction to the second automobile data recorder, namely closing other automobile data recorders except the first automobile data recorder in the preset automobile, and enabling the first automobile data recorder to continue to work.

In addition, when the first video does not have preset information, acquiring the acquisition time of the parking video in the plurality of automobile data recorders, namely the duration of the plurality of automobile data recorders for acquiring the parking video; when the acquisition time of the parking videos in the plurality of automobile data recorders is greater than or equal to a preset first time threshold, the preset first time threshold is the time length of the plurality of automobile data recorders for initially recording the parking videos after receiving the working instruction; and if the fact that the preset information does not exist in the parking videos is confirmed, a preset second instruction is sent to the automobile data recorders, so that the automobile data recorders are in an inactive state at the same time, and consumption of power supply is reduced.

For example, the acquisition time is 7 minutes, the preset first time threshold may be set to 5 minutes, and when the acquisition time is greater than the preset first time threshold, the sending of the sleep command to the plurality of automobile data recorders is confirmed. And when the acquisition time is smaller than the preset first time threshold, the plurality of automobile data recorders continuously acquire parking videos around the preset automobile.

In one possible implementation manner, after the server sends a preset second instruction to the second automobile data recorder, when the first automobile data recorder is in a working state, acquiring the acquisition time of the first video acquired by the first automobile data recorder, wherein the acquisition time is the time difference between the time when the first automobile data recorder starts to acquire and the current time; judging whether the acquisition time of the first video is greater than or equal to a preset second time threshold, wherein the preset second time threshold is the time for normally acquiring the parking video by each automobile data recorder; and when the acquisition time of the first video is greater than or equal to a preset second time threshold, determining to send a preset second instruction to the first driving recorder, namely closing the first driving recorder.

For example, acquiring the acquisition time of the first video, setting the preset second time threshold to 25 minutes when the acquisition time is 30 minutes, and confirming that the dormancy instruction is sent to the first driving recorder to stop the first driving recorder when the acquisition time of the first video is greater than the preset second time threshold. The preset second time threshold may be set according to actual conditions. And when the acquisition time is smaller than a preset second time threshold, the first driving recorder continues to acquire the parking video.

In one possible implementation manner, after the preset second instruction is sent to the second automobile data recorder, the second video collected by the first automobile data recorder is obtained, and the second video refers to the video that the first automobile records and begins to collect after the server sends the preset second instruction to the second automobile data recorder. And if the preset information does not exist in the second video, sending a preset second instruction to the first driving recorder. The situation that the first driving recorder needs to work continuously because the personnel only bypass the preset vehicle is reduced, but the personnel does not exist, and the acquisition time of the first driving recorder is not reached is avoided, the second video acquired can be identified to judge whether preset information exists in the second video, and when the preset information does not exist in the second video, a dormancy instruction is timely sent to the first driving recorder, so that unnecessary power consumption is reduced. When the preset information exists in the second video, the first driving recorder continues to work.
