It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein.

Example 1

Fig. 1 is a flowchart of a vehicle driving video and audio storage method provided in an embodiment of the present invention, where the embodiment is applicable to a situation of timely storing driving video and audio data, the method may be performed by a vehicle driving video and audio storage device, and the device may be implemented in a software and/or hardware manner and may generally be directly integrated in an electronic device for executing the method, where the electronic device may be a terminal device or a server device, and the embodiment of the present invention does not limit a type of the electronic device for executing the vehicle driving video and audio storage method. Specifically, as shown in fig. 1, the vehicle driving video storage method specifically includes the following steps:

s110, acquiring driving video and audio data to be stored of a preset frame number; the driving video data to be stored comprise driving video data to be stored and/or driving audio data to be stored.

The preset frame number may be a preset frame number for acquiring the driving video and audio data to be stored. The driving video data to be stored can be video data in the driving process of the vehicle to be stored. The driving video data to be stored may be video data during driving of the vehicle to be stored. The driving audio data to be stored may be audio data during driving of the vehicle to be stored.

In the embodiment of the invention, the preset frame number of the video data of the driving to be stored is acquired, the preset frame number of the audio data of the driving to be stored is acquired, or the preset frame number of the video data of the driving to be stored and the audio data of the driving to be stored are acquired at the same time.

Exemplary, the method for obtaining the audio-video data of the driving to be stored with the preset frame number may obtain one frame of audio-video data of the driving to be stored, or may obtain multiple frames of audio-video data of the driving to be stored, which is not limited in the embodiment of the present invention.

And S120, carrying out data encoding processing on the driving video and audio data to be stored to obtain encoded video and audio data.

The encoded audio-visual data may be data obtained by encoding the driving audio-visual data to be stored.

In the embodiment of the invention, after the driving video data to be stored with the preset frame number is obtained, the driving video data to be stored can be further subjected to data encoding processing to obtain encoded video data. It can be understood that the data encoding process is performed on the driving video data to be stored, and the data encoding process may be performed on each frame of the driving video data to be stored. That is, if the multi-frame driving video and audio data to be stored is obtained, the multi-frame encoding video and audio data can be obtained.

S130, determining a preset storage space of a first storage module to store the encoded video and audio data into the preset storage space; wherein the first memory module is a ferroelectric memory module.

The first storage module may be a module for storing the driving video and audio data to be stored, for example, may be a ferroelectric storage module. The preset storage space may be a space in the preset first storage module for storing the driving video and audio data to be stored.

In the embodiment of the invention, after the driving video data to be stored is subjected to data encoding processing to obtain the encoded video data, the preset storage space of the first storage module can be further determined so as to store the encoded video data into the preset storage space. It should be noted that, if the preset frame number is multiple frames, the storage space occupied by the encoded audio-visual data of the preset frame number needs to be smaller than the preset storage space of the first storage module. It may be understood that if multi-frame encoded audio-visual data is obtained, the multi-frame encoded audio-visual data may be stored in the preset storage space at the same time, or the frame encoded audio-visual data may be stored in the preset storage space after each frame of encoded audio-visual data is obtained, which is not limited in the embodiment of the present invention.

Note that the ferroelectric memory (FRAM, ferroelectric RAM) is a nonvolatile memory, which combines the advantages of the RAM (Random Access Memory ) and the nonvolatile memory, and has high read-write durability and a fast writing speed. However, since the ferroelectric memory is expensive, if all the video and audio data are stored in the ferroelectric memory, the cost of the tachograph is too high. Therefore, the ferroelectric memory module has smaller preset memory space, i.e. less encoded video and audio data is stored in the ferroelectric memory module.

According to the technical scheme, the driving video data to be stored of the preset frame number is obtained, the driving video data to be stored is subjected to data encoding processing to obtain encoded video data, the preset storage space of the first storage module is determined, so that the encoded video data is stored in the preset storage space, the problem that the driving video data cannot be stored completely in the prior art is solved, the driving video data can be stored timely, and therefore the complete storage of the driving video data is achieved.

Example two

Fig. 2 is a flowchart of a vehicle driving video and audio storage method according to a second embodiment of the present invention, where the foregoing technical solutions are further refined, and various specific alternative implementations are provided after the encoded video and audio data is stored in the preset storage space and the data encoding process is performed on the driving video and audio data to be stored to obtain the encoded video and audio data. The technical solution in this embodiment may be combined with each of the alternatives in one or more embodiments described above. As shown in fig. 2, the method may include the steps of:

s210, acquiring driving video and audio data to be stored of a preset frame number; the driving video data to be stored comprise driving video data to be stored and/or driving audio data to be stored.

Optionally, the data acquisition module of the automobile data recorder may acquire the to-be-stored automobile data, or may acquire the to-be-stored automobile data in any other manner, which is not limited in the embodiment of the present invention.

S220, carrying out data encoding processing on the driving video and audio data to be stored to obtain encoded video and audio data.

Optionally, the data encoding module of the automobile data recorder may perform data encoding processing on the automobile data to be stored, or may perform data encoding processing on the automobile data to be stored in any other way, which is not limited in the embodiment of the present invention.

Optionally, after performing data encoding processing on the driving video and audio data to be stored to obtain encoded video and audio data, the method further includes: acquiring coded video and audio data in a preset time period; storing the coded video and audio data in a preset time period into a second storage module; the second storage module is an external hard disk storage module.

The preset time period may be a preset time period, for example, may be 3 seconds, or may be 5 seconds, which is not limited in the embodiment of the present invention. The second storage module may be another module for storing the driving video and audio data to be stored, for example, may be an external hard disk storage module.

In the embodiment of the invention, after the data encoding processing is performed on the driving video and audio data to be stored to obtain the encoded video and audio data, the encoded video and audio data in the preset time period can be further obtained, so that the encoded video and audio data in the preset time period can be stored in the second storage module. It can be understood that, because the writing times of the external hard disk storage module are limited and the writing speed is slower, when the external hard disk storage module is written, the coded video and audio data in the preset time period can be written once, and more coded video and audio data can be stored in the external hard disk storage module, namely, the video and audio data with a longer time can be stored in the external hard disk storage module for a user to check.

It should be noted that if the number of the obtained encoded audio/video data cannot meet the number of the encoded audio/video data in the preset time period, waiting may be performed until the number of the encoded audio/video data in the preset time period is met. For example, assuming that the preset time period is 3 seconds, and the 1 second encoded audio-visual data includes 25 frames of encoded audio-visual data, the encoded audio-visual data in the preset time period may be 75 frames of encoded audio-visual data, and if 5 frames of encoded audio-visual data are obtained, waiting may be performed until 75 frames of encoded audio-visual data are obtained.

S230, determining a preset storage space of a first storage module, and determining whether an available storage space exists in the preset storage space; if yes, executing S240; otherwise, S250 is performed.

Wherein the available storage space may be available storage space. It is understood that the available storage space may be less than or equal to the preset storage space.

In the embodiment of the invention, after the data encoding processing is performed on the driving video and audio data to be stored to obtain the encoded video and audio data, the preset storage space of the first storage module can be further determined, and whether the available storage space exists in the preset storage space or not is determined. If the available storage space exists in the preset storage space, the target storage position of the coded video and audio data can be determined in the available storage space. If the available storage space does not exist in the preset storage space, the to-be-covered video and audio data in the first storage module can be determined, so that the to-be-covered storage position of the to-be-covered video and audio data is determined to be the target storage position of the coded video and audio data.

Optionally, the duration of the audio-visual permission corresponding to the preset storage space is greater than the duration of the audio-visual permission corresponding to the preset time period.

The audio-visual time allowed to be stored may be an audio-visual time allowed to be stored in a preset storage space, for example, 5 seconds of audio-visual data may be allowed to be stored in the preset storage space, 7 seconds of audio-visual data may be allowed to be stored in the preset storage space, and the embodiment of the invention is not limited in this way. It may be appreciated that the allowable audio-visual duration may be an audio-visual duration stored in the first storage module. The audio-visual duration of the time period may be an audio-visual duration included in a preset time period. It can be understood that the audio-visual duration of the time period can be the audio-visual duration of each writing into the second storage module.

Specifically, the allowable audio-visual storage time length corresponding to the preset storage space is longer than the audio-visual time length of the time period corresponding to the preset time period, that is, the audio-visual time length stored in the first storage module can be longer than the audio-visual time length written into the second storage module each time.

S240, determining a target storage position of the coded video and audio data in the available storage space.

The target storage location may be a storage location of the encoded audio-visual data in the first storage module.

In the embodiment of the invention, after determining that the available storage space exists in the preset storage space, the target storage position of the encoded video and audio data can be further determined in the available storage space. It should be noted that, the embodiment of the present invention does not limit a specific implementation manner of determining the target storage location of the encoded audio-visual data in the available storage space, as long as the determination of the target storage location of the encoded audio-visual data in the available storage space can be achieved.

S250, determining the video and audio data to be covered in the first storage module.

The video data to be covered may be video data to be covered, which is stored in the first storage module. It can be appreciated that when there is no available storage space in the preset storage space, if the encoded audio-visual data is stored in the preset storage space, the stored audio-visual data needs to be covered.

In the embodiment of the invention, after determining that the available storage space does not exist in the preset storage space, the audio-visual data to be covered in the first storage module can be further determined.

Optionally, determining the audio-visual data to be covered in the first storage module may include: determining storage time stamp data of each storage video and audio data in the first storage module; determining target timestamp data in the stored timestamp data; and determining the stored video and audio data corresponding to the target time stamp data as video and audio data to be covered.

The audio-visual data stored in the first storage module can be audio-visual data stored in the first storage module. The stored time stamp data may be stored time stamp data corresponding to the audio-visual data. It will be appreciated that the storage time stamp data may be used to identify the time and order in which the storage of the audiovisual data was stored in the first storage module. The target timestamp data may be a target value in each stored timestamp data, for example, may be timestamp data of an earliest time in each stored timestamp data, which is not limited by the embodiment of the present invention.

Specifically, after determining that the available storage space does not exist in the preset storage space, the storage timestamp data of each storage video data in the first storage module can be further determined to determine the target timestamp data in each storage timestamp data, so that the storage video data corresponding to the target timestamp data is determined to be the video data to be covered.

S260, determining the storage position to be covered of the video and audio data to be covered as the target storage position of the encoded video and audio data.

The storage position to be covered may be a storage position of the audio-visual data to be covered in the first storage module.

In the embodiment of the invention, after the to-be-overlaid video and audio data in the first storage module is determined, the to-be-overlaid storage position of the to-be-overlaid video and audio data can be further determined as the target storage position of the encoded video and audio data.

S270, storing the coded video and audio data to the target storage position.

In the embodiment of the invention, after the target storage position of the encoded video and audio data is determined, the encoded video and audio data can be further stored in the target storage position.

In a specific example of an embodiment of the present invention, the automobile data recorder may include a data acquisition module, a data encoding module, a ferroelectric memory module, and an external hard disk memory module. Specifically, after the data acquisition module acquires data (i.e. to-be-stored driving video and audio data), the data is encoded by the data encoding module, and the encoded data (i.e. the encoded video and audio data) is immediately written into the ferroelectric memory (i.e. the first storage module). Meanwhile, the coded data is cached, and the data cached for 3 seconds (namely, the preset time period) is written into an external hard disk memory (namely, a second storage module) for long-term storage. Specifically, only 5 seconds (i.e. the duration of video and audio is allowed to be stored) of data is reserved in the ferroelectric memory, and after the storage time exceeds 5 seconds, the storage data at the earliest time (i.e. the video and audio data to be covered) is covered and stored, so that the latest 5 seconds of data are stored in the ferroelectric memory. When the encoded data is acquired, the encoded data is immediately written into the ferroelectric memory, and no buffer and no waiting time are needed. It will be appreciated that when a serious traffic accident occurs in the vehicle, longer time data may be obtained in the external hard disk memory and the last 5 seconds of data at the time of the accident may be obtained in the ferroelectric memory.

According to the technical scheme, the problem that key video and audio data are lost when all external power supplies of the automobile data recorder are damaged in an extreme automobile accident is solved, and the fact that the equipment is suddenly powered down can be ensured to store video at the last moment through the mode of storing the data in real time by the ferroelectric memory FRAM is solved.

According to the technical scheme, the driving video and audio data to be stored of the preset frame number are obtained, the driving video and audio data to be stored are subjected to data encoding processing to obtain encoded video and audio data, and the preset storage space of the first storage module is determined to determine whether available storage space exists in the preset storage space. And when the available storage space exists in the preset storage space, determining the target storage position of the coded video and audio data in the available storage space. And when the available storage space is not determined to exist in the preset storage space, determining the to-be-covered video and audio data in the first storage module, so as to determine the to-be-covered storage position of the to-be-covered video and audio data as a target storage position of the coded video and audio data. Therefore, the encoded video and audio data is stored to the target storage position, the problem that the existing vehicle video and audio data cannot be completely stored is solved, the vehicle video and audio data can be timely stored, and the complete storage of the vehicle video and audio data is realized.
