The invention provides an alarm method based on a vehicle event data recorder.

In the embodiment of the present invention, as shown in fig. 1, the alarm method based on the automobile data recorder includes:

and S10, when the driving record detects that the automobile is abnormal, sending alarm information to the remote terminal.

It is worth explaining that, the automobile data recorder of the basic technical scheme of the application has an alarm function besides a basic video recording function. The alarm function is specifically to give out an alarm sound to remind people in the automobile when the abnormal running condition of the automobile is detected. However, the automobile data recorder can only provide a prompt at a local end, and various limitations exist.

Aiming at the problems of the automobile data recorder, the technical scheme of the invention detects the condition of the automobile by using the automobile data recorder, and when the automobile data recorder detects the abnormal condition of the automobile, the remote terminal can be informed at the first time, so that a user of the remote terminal can know the abnormal condition of the automobile at the first time. Particularly, when a serious car accident occurs during the driving process of the automobile and people (including a driver and passengers) in the automobile are seriously injured and cannot give an alarm independently, the automobile data recorder of the embodiment can give an alarm to a user of the remote terminal after giving the alarm to the remote terminal, so that the user can avoid missing the optimal rescue time. Therefore, the alarm method based on the automobile data recorder has the advantages of expanding the alarm function of the automobile data recorder and providing more perfect guarantee for the safety of personnel in the automobile.

It should be noted that, a user of the remote terminal may be generally set as a relative or a friend of a car owner, and the remote terminal may be a mobile phone, a smart watch, a tablet computer, a notebook computer, a desktop computer, or the like having a network connection function.

Further, in the present embodiment, the abnormal condition of the automobile includes a collision, a fall, a slip, or a sharp turn. Among them, collision, slippage and sharp turning are common conditions of automobiles in the event of traffic accidents, and dropping is a relatively rare case. Of course, the abnormal condition of the vehicle is not limited to the above-mentioned several conditions, and may include emergency braking.

Specifically, in the present embodiment, the alarm information includes a trigger signal for triggering an alarm of the remote terminal and abnormal information for reflecting the abnormal condition. The triggering signal is used for triggering the remote terminal to alarm after the abnormal condition of the automobile occurs, and at the moment, a user of the remote terminal can know that the corresponding automobile occurs the abnormal condition. The abnormal information can reflect the abnormal condition, so that the user of the remote terminal can know what the specific abnormal condition of the automobile is. Of course, the design of the present application is not limited thereto, and in other embodiments of the present application, the alarm information may also include only a trigger signal for triggering an alarm of a remote terminal, or abnormal information for reflecting an abnormal condition.

It should be noted that after receiving the trigger signal of the remote terminal, the remote terminal may send the prompt message in the manner of ringing, vibrating, flashing a flash lamp, flashing a screen, and the like.

Specifically, the abnormality information includes at least one of video information, voice information, text information, and position information. Among them, the amount of data to be transmitted by the video information is large, and the video information can feed back various conditions of the accident scene in detail when the signal is good. The data volume to be transmitted by the voice information and the text information is small, and under the condition of poor signal, the automobile data recorder can send the voice information and/or the text information to the remote terminal so as to explain the current condition of the automobile to a user of the remote terminal. It should be noted that, because the car recorder can detect the status of the car, when the car recorder sends the voice message, the voice message may be the collected voice of the person in the car, or the preset voice message corresponding to various abnormal conditions in the car recorder according to the current car status. The text information may be text information actively entered by a vehicle occupant, or may be text information obtained by converting voice of the vehicle occupant into text, or preset text information corresponding to various abnormal conditions in the vehicle event data recorder.

The location information may inform the user of the remote terminal of the current location of the vehicle so that the user of the remote terminal can know the location of the vehicle. Specifically, the automobile data recorder comprises a positioning module, and the positioning module is used for positioning the position of the automobile, so that the position information required by alarming can be provided through the positioning module. For example, the positioning module may be a GPS navigation module or a beidou navigation module. It should be noted that, according to different product models, the abnormal information sent by the automobile data recorder may include one, two, three or all four of video information, voice information, text information and position information.

Further, as shown in fig. 2, the alarm method based on the automobile data recorder of the embodiment further includes:

s20, setting the time node of the abnormal condition of the automobile in the driving state as a first accident occurrence node;

s21, uploading image data collected by the automobile data recorder within a first preset time before the node occurs in the first accident, and/or uploading image data collected by the automobile data recorder within a second preset time after the node occurs in the first accident to a cloud, and/or using the image data as alarm information.

The automobile data recorder can upload image data collected in a first preset time before a node occurs in a first event and image data collected in a second preset time after the node occurs in the first event to a cloud end, and the image data are sent to a remote terminal as alarm information. Therefore, the problem that the accident evidence is lost due to the fact that the image data stored in the automobile data recorder is damaged when an accident happens can be solved. Therefore, the alarm method based on the automobile data recorder can also save the image data in the cloud when the automobile is in an abnormal condition, so that the stability of accident evidence storage is ensured, and later-period accident restoration and responsibility determination are facilitated. It is worth to say that, in this embodiment, the vehicle event data recorder sends the image data collected in the first preset time before the node occurs in the first event and the image data collected in the second preset time after the node occurs in the first event to the cloud, and sends the image data to the remote terminal as the alarm information. In other embodiments, the automobile data recorder may only send the image data collected within a first preset time before the first event occurrence node, or send the image data collected within a second preset time after the first event occurrence node to the cloud and the remote terminal. It should be noted that, in the case of sufficient bandwidth (i.e., good signal), the image data collected by the vehicle event data recorder (image data collected before or after an accident) can be sent to the cloud and the remote terminal at the same time. In the case of insufficient bandwidth (i.e., poor signal), the image data collected by the automobile data recorder is only transmitted to the cloud or the remote terminal, and the priority of uploading the image data to the cloud is higher than that of uploading the image data to the remote terminal.

Specifically, in the present embodiment, the first preset time is at least 30 seconds and at most 60 seconds; the second predetermined time is at least 30 seconds and at most 60 seconds. It can be appreciated that the process of an accident is typically instantaneous or transient, so that only the collected image data in a short period of time need be uploaded to the cloud and used as alarm information. Meanwhile, the time length of image acquisition is limited, the size of image data to be transmitted can be limited, and the image data can be uploaded timely and quickly. For example, the first preset time may be 30 seconds, 35 seconds, 40 seconds, 45 seconds, 50 seconds, 55 seconds, 60 seconds; the second preset time may be 30 seconds, 35 seconds, 40 seconds, 45 seconds, 50 seconds, 55 seconds, 60 seconds.

Therefore, the automobile reminding device can remind an automobile owner or a preset contact person of the automobile of the abnormal situation, and can store evidences for later-stage case processing. It is worth mentioning that, in this embodiment, the automobile data recorder sends the image data collected within a third preset time after the second accident occurs to the cloud, and sends the image data to the remote terminal as alarm information. It should be noted that, in other embodiments, the automobile data recorder may also send only image data acquired within a third preset time after the second accident occurrence node to the cloud or the remote terminal.

Specifically, in the present embodiment, the third preset time is at least 30 seconds and at most 60 seconds. It can be appreciated that the process of an accident is typically instantaneous or transient, so that only the collected image data in a short period of time need be uploaded to the cloud and used as alarm information. Meanwhile, the time length of image acquisition is limited, the size of image data to be transmitted can be limited, and the image data can be uploaded timely and quickly. For example, the third preset time may be 30 seconds, 35 seconds, 40 seconds, 45 seconds, 50 seconds, 55 seconds, 60 seconds.

Specifically, the abnormality information includes at least one of video information, voice information, text information, and position information. Among them, the amount of data to be transmitted by the video information is large, and the video information can feed back various conditions of the accident scene in detail when the signal is good. The amount of data to be transmitted between the voice message and the text message is small, and in the case of a poor signal, the alarm module 30 may send the voice message and/or the text message to the remote terminal 200 to explain the current status of the vehicle to the user of the remote terminal 200. It should be noted that, because the alarm module 30 can detect the status of the vehicle, when the alarm module 30 sends the voice message, the voice message may be the collected voice of the vehicle occupant, or the alarm module 30 may preset the voice message corresponding to various abnormal conditions in the car event recorder 100 according to the current vehicle status. The text information may be text information actively entered by the vehicle occupant, or may be text information obtained by converting the voice of the vehicle occupant into text, or preset text information corresponding to various abnormal conditions in the drive recorder 100.

The location information may inform the user of remote terminal 200 of the current location of the vehicle so that the user of remote terminal 200 may know the location of the vehicle. Specifically, the automobile data recorder 100 further includes a positioning module (not shown) disposed on the automobile data recorder body 10 for positioning the position of the automobile, so that the positioning module can provide the position information required for alarming. For example, the positioning module may be a GPS navigation module or a beidou navigation module.
