Detailed Description

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments.

Intelligent driving and safety monitoring of vehicles have been attracting attention, and along with the development of vehicle intellectualization, many vehicle control systems integrate digital video recorders, sentry modes and other functions.

Digital video recorders (digital video recorder, DVR), also known as hard disk recorders, use hard disk recordings as opposed to traditional analog video recorders. A DVR is a device mounted on a car to photograph a plurality of angles. The DVR uses advanced video and audio coding and decoding technology to carry out digital-to-analog conversion and compression storage on videos inside and outside the automobile. Some vehicles' DVRs may also perform GPS positioning, vehicle-mounted entertainment playback, wireless network transmission, etc. The DVR can record related information such as images and sounds during the running of the vehicle, record video images and sounds during the whole running process of the vehicle, provide evidence for traffic accidents, reduce disputes and the like.

The sentinel mode refers to the fact that after a specified area is parked and locked, the system automatically monitors suspicious activity around the vehicle. When suspicious behavior is detected, the vehicle will react according to the severity of the threat. If a serious threat is detected, the vehicle camera will begin recording video and activate the alarm system. The mobile phone application of the vehicle will send a message to alert the user that an accident may occur.

Typically, the file data generated by the digital video recorder or the sentinel mode is stored in an on-board external memory, such as a usb disk, a Secure Digital (SD) card, etc. Taking a USB flash disk as an example, the USB flash disk is connected with a vehicle-mounted system by adopting a universal serial bus (universal serial bus, USB). USB is an external bus standard for standardizing the connection and communication of a computer with external devices.

The digital video recorder and the sentry mode are usually recorded circularly, for example, a 128G USB flash disk is used, if the vehicle is in the sentry mode, the video file stored first in the sentry mode can be automatically covered and deleted to continue recording after the vehicle is fully stored, and the process is repeated. The USB flash disk can be taken down, and data on the USB flash disk can be backed up to other electronic equipment.

In some vehicles, if the usb flash disk is not inserted, the sentinel mode may receive a notification on the mobile APP when entering the alarm state, but no video recording is performed, and the key video data may be lost.

With the development of vehicle intellectualization, video data generated by service modules such as a digital video recorder and a sentinel mode occupy a larger space, and the storage space of a plurality of service modules such as the sentinel mode is not reasonably configured to influence the functions of the vehicle service modules, so that the intellectualization of the vehicle is influenced.

Therefore, how to develop a reasonable vehicle-mounted file storage management scheme is a problem to be solved.

Based on this, the embodiment of the application proposes a storage management system of a vehicle. Fig. 1 is a schematic flow chart of a storage management system of a vehicle according to an embodiment of the present application. The storage management system of the vehicle of fig. 1 may be a storage management system under a single operating system, which may be, for example, an android (android) system. The storage management system of the vehicle of fig. 1 may also be configured as a storage management system under a dual operating system, which may be, for example, an android system and a Linux system. The following describes in detail a storage management system of a vehicle according to an embodiment of the present application with reference to fig. 1. As shown in fig. 1, the storage management system 100 of the vehicle may include an application program interface layer 110, a capacity configuration module 120, a capacity management module 130, and a database management module 140.

The application program interface layer 110 may be connected to a plurality of service modules of the vehicle, and is configured to perform access operation on service data generated by the plurality of service modules of the vehicle. The application program interface layer 110 is provided with an application program interface through which an application program can interact with service data of a plurality of service modules.

In some implementations, the application program interface may be used to perform at least one of the following operations: storing service data; searching service data; deleting service data; and coverage of service data. I.e. the application program interface may be used to perform CRUD operations. CRUD refers to add (Create), read, update, and Delete (Delete) operations at the time of the computing process, and is primarily used to describe the basic operational functions of a database or persistence layer in a software system. The file information aiming at the service module can be uniformly written into the database to uniformly manage the related information of the file, so that the searching of the file can be uniformly operated on the database, and the searching speed is increased.

The capacity configuration module 120 is connected to the application program interface layer 110, and is configured to obtain a storage space of a storage device of the vehicle, and configure a plurality of storage spaces corresponding to the plurality of service modules one by one according to the storage space of the storage device. The storage spaces are respectively used for storing service data generated by the service modules, the service modules are all in a system self-starting mode, and the service data are stored in a cyclic coverage mode based on preset rules.

The storage devices of the vehicle may include an internal storage device and an external storage device. Internal storage devices such as memory, cache, hard disk, etc. of the storage management system; external storage devices such as SD cards, USB discs connected through USB interfaces, and the like. The internal storage device and the external storage device of the vehicle are collectively referred to as a local storage device. The storage capacity or storage space, the storage space of the storage device or storage capacity of the storage device, which is not differentiated by the embodiments of the present application. The storage space of the storage device may include total space, used space, remaining space, and the like.

The plurality of service modules may refer to service modules that generate multimedia data such as video, pictures, etc. The plurality of business modules may include a sentinel mode module, a vehicle recorder, etc., wherein the sentinel mode module may be referred to as a sentinel module for short. The video data generated by the service module is typically streaming data. The streaming data may include at least one group of pictures (group of pictures, GOP), one GOP including one I frame, a plurality of B frames, and a plurality of P frames.

The plurality of service modules of the vehicle are usually operated in a background service mode after the system is started, namely a system self-starting mode.

The plurality of service modules can be configured as storage spaces with the same capacity or as storage spaces with different capacities. For example, according to the storage space of the storage device, a plurality of storage spaces corresponding to a plurality of service modules of the vehicle one by one can be configured according to a certain proportion relation. Generally, the larger the storage space of the storage device, the larger the configuration storage space corresponding to the plurality of service modules.

The capacity allocation module 120 may perform customized capacity allocation for a plurality of service modules for different storage spaces. For example, when the total storage space of the storage device is 10G and the remaining storage space is 6G, the storage space of the sentinel module may be configured to be 2G and the storage space of the automobile data recorder module may be configured to be 3G.

In some implementations, the capacity of the plurality of service modules may be configured for different sizes of storage space, and the capacity of the plurality of service modules may have different scale setting ranges for different storage space ranges. For example, when the total storage space is 10G or less, the storage space configuration ratio of the sentinel module and the automobile data recorder may be 1:2; when the total storage space is 10G-20G, the storage space configuration ratio of the sentinel module and the automobile data recorder can be 1:3.

The capacity allocation module 120 may allocate a plurality of storage spaces corresponding to a plurality of service modules of the vehicle one by one according to the storage spaces of the storage devices and the type information of the service modules. For example, in some implementations, where the vehicle is often in a sentinel mode for a period of time, the memory space corresponding to the sentinel module may be configured to be larger in order to store more video files, increase the cycle coverage period of the files, help to improve the resolution of the video data, and so on. In some embodiments, the vehicle is in a driving state for a long time, and the storage space corresponding to the automobile data recorder can be configured to be larger.

In some embodiments, after the system is started, the capacity configuration module 120 may pre-configure a plurality of storage spaces corresponding to a plurality of service modules of the vehicle one-to-one according to the total storage space, the remaining storage space and the used storage space of the storage device. And respectively storing the service data generated by the service modules into the corresponding storage spaces according to the preconfigured storage spaces. For example, the service data such as the video and the picture generated by the sentry module are stored in the storage space corresponding to the sentry module, and the service data such as the video and the picture generated by the automobile data recorder are stored in the storage space corresponding to the automobile data recorder.

The service data generated by the plurality of service modules is typically video data that is stored continuously in time order. The storage of the service data is cyclic coverage storage based on preset rules. The loop overlay storage is alternatively referred to as loop overlay, loop delete. The service data file (video) with the longest storage date can be deleted first by circularly overlaying storage, and the service data file with the longest file number can be deleted first. The preset rule may be to delete the service data with the longest storage date first, or delete the service data with the longest file number first. The cyclic coverage storage based on the preset rule may be cyclic coverage according to a certain period of time, or cyclic coverage may be performed according to a certain capacity.

For example, in the manner of performing the cyclic coverage according to the capacity, when the remaining capacity of the service module is smaller than the corresponding remaining capacity threshold, the newly generated service data may be stored in the manner of the cyclic coverage. In some implementations, the cyclic overlay may also delete only the service data (video) of the lowest security level that is the longest in storage date, and not the service data of the higher security level, taking into account the different security levels of the service data.

And if the residual capacity of the storage space corresponding to the service module is smaller than the corresponding residual capacity threshold value, performing cyclic coverage based on a preset rule on the newly generated service data.

During normal operation of the system, the plurality of memory spaces of the plurality of business modules, which correspond one-to-one, are typically no longer changed. In some embodiments, after the system is restarted, the multiple storage spaces corresponding to the multiple service modules one to one may be reconfigured according to the total storage space, the remaining storage space, the used storage space information, and the preset adjustment conditions of the storage device.

The capacity management module 130 is connected to the capacity configuration module 120, and the capacity management module 130 is configured to scan a plurality of storage spaces; and monitoring capacity information corresponding to each of the plurality of storage spaces according to the scanning result, wherein the capacity information comprises used capacity information and residual capacity information of the storage spaces.

The capacity information of the storage space corresponding to each of the plurality of service modules is obtained through scanning, so that the capacity service conditions of the plurality of service modules, such as the information of service time, total capacity, used capacity, residual capacity, the duty ratio of the used capacity to the total capacity and the like, can be obtained.

The capacity configuration module 120 is further configured to obtain capacity information corresponding to each of the plurality of storage spaces from the capacity management module 130, and adjust the plurality of storage spaces according to the capacity information corresponding to each of the plurality of storage spaces.

The database management module 140 is connected to the application program interface layer 110, and is configured to manage service data generated by a plurality of service modules based on a database.

According to the embodiment of the application, the capacity information corresponding to the storage spaces is monitored, and the storage spaces can be reasonably and dynamically configured. The method is beneficial to reasonably configuring the storage spaces corresponding to the service modules, and the functions of the service modules are better played.

The capacity of the internal memory of the vehicle is typically fixed, limited, and the vehicle is typically also connectable to external storage devices, such as a USB flash disk. The external storage device is large in storage capacity and extensible, such as a USB flash disk, is in quick plug connection, and is convenient for copying and outputting service data. The system can perform unified storage management on the external storage device and the internal storage device.

Before configuring storage spaces corresponding to a plurality of business modules, it is generally necessary to calculate the storage space of the storage device of the vehicle. In some implementations, the capacity configuration module 120 is to: monitoring whether the vehicle is connected with an external storage device; and if the vehicle is in a connection state with the external storage device, acquiring a storage space from the external storage device, and taking the external storage device as a target storage area of the service modules. And if the vehicle is in a disconnected state with the external storage device, acquiring the storage space from the internal storage device of the vehicle, and taking the internal storage device as a target storage area. The external storage device is also used for backing up high-priority data in the service data stored by the internal storage device, so that unified processing of the external storage device and the internal storage device of the vehicle is facilitated.

In some implementations, the capacity management module 130 may employ the same scanning thread for scanning multiple storage spaces, or may employ different scanning threads. In some embodiments, one scanning thread may be independently turned on for each business module. For example, different threads are adopted to scan the storage spaces corresponding to the sentry modules and the automobile data recorder, so that mutual interference among different service modules can be reduced to the greatest extent, and more system resources can be occupied. In some embodiments, the number of scanning threads can be dynamically adjusted, so as to achieve better cost performance according to the actual conditions of the system load and the service modules. Such schemes typically require some scheduling policy and algorithm support.

In some implementations, the capacity management module 130 is configured to monitor, via the first scanning thread, whether the vehicle is connected to an external storage device; if the vehicle is connected with the external storage device, judging whether the external storage device meets the preset condition; when the vehicle is connected with the external storage device and the external storage device meets a preset condition, the capacity management module 130 is configured to return to an external storage path, where the external storage path is a path for storing service data generated by a plurality of service modules to the external storage device; if the vehicle is not connected to an external storage device, the capacity management module 130 is configured to return an internal storage path, which is a path for storing service data generated by a plurality of service modules to the internal storage device. The preset condition may be that the external storage device (USB device) is an external storage device authenticated by the vehicle, or that the external storage device is a USB device that meets the authentication requirement of the vehicle, or that the capacity of the external storage device meets the minimum capacity requirement. The preset conditions are not particularly limited in the embodiment of the present application.

In some implementations, the capacity management module 130 is configured to create a plurality of capacity scan threads that are in one-to-one correspondence with the plurality of traffic modules; and scanning a plurality of storage spaces corresponding to the service modules by using a plurality of capacity scanning threads respectively, and sending capacity information corresponding to the storage spaces to the capacity configuration module 120. For example, a folder and a scanning thread for storing video data can be generated according to whether a USB is inserted and provided service module list (sentinel/DVR) information, and then up-summarizing is performed according to service data scanned by different service threads, so as to collect total storage space, used storage space, residual storage space and the like of each service module.

After the storage management system is restarted, a certain amount of resources and time are generally consumed for calculating the storage space of the storage device, and then a plurality of storage spaces corresponding to a plurality of service modules of the vehicle one by one are configured. The larger the storage space of the storage device, the more used space the service data occupies, generally the longer the computation time.

In some implementations, the capacity configuration module 120 is further configured to store capacity information of the plurality of storage spaces into a memory of the vehicle to form a memory snapshot; and storing the memory snapshot to a local storage device of the vehicle, such as a hard disk, to form the local snapshot. After the storage management system is restarted, the capacity information corresponding to each of the storage spaces is determined according to the memory snapshot (or the local snapshot). This helps to reduce the storage space computation time of the storage device, providing response timeliness and efficiency of the storage management system.

The memory snapshot, as the name implies, takes a picture of the memory, records the data in the memory at a certain moment, and saves the data on the hard disk in the form of a file. The memory snapshot may be updated periodically to the local storage device, e.g., the memory snapshot may be updated to the local hard disk before the storage management system shuts down.

The capacity configuration module 120 is further configured to adjust the plurality of storage spaces according to the capacity information and the first adjustment condition corresponding to each of the plurality of storage spaces.

The first adjustment condition may be that the change amount of the capacity information of the storage space of the service module exceeds a preset threshold value within a preset time, and capacity adjustment is required after the first adjustment condition is satisfied. For example, the first adjustment condition may be that a change amount of the used capacity information of the storage space of the service module exceeds a preset threshold, or that a change amount of a ratio of the used capacity information to the total capacity information exceeds a preset threshold. For example, in the historical preset time, if the change amount of the used capacity information of the storage space of the automobile data recorder module exceeds the preset threshold, that is, the first adjustment condition is satisfied, the storage space of the automobile data recorder module can be adjusted. If the ratio variation of the used capacity to the total capacity of the storage space of the automobile data recorder module is 80% within a preset time (one week), and exceeds a preset threshold value of 70%, that is, the first adjustment condition is satisfied, the storage space of the automobile data recorder module can be reset, and the corresponding storage space configuration of the automobile data recorder module can be increased.

The database management module 140 manages service data generated by a plurality of service modules based on a database. Databases refer to software systems used in computer systems to organize, store, and manage data. Databases typically occupy a certain amount of memory space and require management and optimization to ensure the performance and reliability of the database. Scanning and monitoring of the storage space helps to ensure adequate and reasonable utilization of the storage space. First, the scanning and monitoring of storage space may help identify and free up unnecessary storage space, thereby providing more space for the database. Secondly, the management and optimization of the database needs to consider the use condition of the storage space, including the allocation, backup, recovery and the like of the storage space.

The storage management system 100 may manage service data generated by the plurality of service modules based on a database. The database management module 140 may perform the following operations: receiving a query request, wherein the query request is used for querying target service data from service data generated by a plurality of service modules; and responding to the query request, and searching the target service data through the database. The target business data may be, for example, video file data, image file data, or event information at a time in the sentinel module.

In some implementations, the storage management system 100 may include a common layer. The generic layer is connected to the application program interface layer 110, the database management module 140 and the capacity configuration module 120, and is used for implementing data interaction between the database management module 140 and/or the capacity configuration module 120 and the application program interface layer 110. The generic layer may include one or more of the following functions: generating a service module catalog, acquiring a service module path, storing pre-verification, acquiring a service module data table, deleting coverage judgment, generating an ID (identity) strategy and the like.

In some implementations, the storage management system 100 performs unified management encapsulation, identification, and parsing of the business data. The main process may include the steps of:

and (3) packaging: the storage management system may provide a uniform (universal) package format for the service data, such as MP4, AVI, etc., for use by different applications. The application may package the business data into this generic format. And (3) identification: the encapsulation format of the service data may be identified, for example, by checking header information of the service data. Different processing modes can be provided for data in different formats. Analysis: the storage management system can perform corresponding analysis according to the format of the service data. For example, for MP4 format video data, information such as audio, video, subtitles, etc. may be parsed to facilitate playing or editing. Through these steps, the storage management system 110 can uniformly manage service data in different formats and provide a uniform interface for application programs, thereby improving the usability and expandability of the data.

Traffic data may be classified into a number of different priorities, high priority data or data known as high security level, high threat level data. In some implementations, video data generated in the sentinel mode may be classified into several levels, such as alert, alarm, severe threat (alert), for example, according to threat level. For example, the safety level of people depending on the car body and scraping the car can be a warning level, and illegal intrusion into the car can be a serious threat level.

In some implementations, the vehicle is not connected to the external storage device at first, the spaces of the service modules are set in the internal storage device, and the service data generated by the service modules are stored in the corresponding storage spaces of the internal storage device. And then, the connection of the vehicle and the external storage device is monitored, the external storage device is used as a target storage area of a plurality of service modules, and a plurality of storage spaces corresponding to the service modules of the vehicle one by one are reconfigured. Typically, the internal storage device has stored thereon a portion of the traffic data. In some embodiments, the important file data of the business module on the internal storage device may be copied to the external storage device, such as storing the high priority (high threat level) video data of the sentinel module to the U disk, and deleting the remaining business data. In some embodiments, the service data of the service module on the internal storage device may be deleted directly.

For example, when an external storage device (U disk) is not connected, video with illegal invasion is stored in the internal storage device; after the external storage device is connected, the illegal intrusion video stored in the internal storage device can be dumped to the external storage device. Thus, the method is beneficial to reducing the storage space occupied by the internal storage device and can also backup the service data with high security level.

In some implementations, the capacity configuration module 120 is further configured to configure, on a storage device of the vehicle, a shared storage space for remaining service modules of the vehicle other than the plurality of service modules; and storing the service data of the rest service modules into the shared storage space. And according to the capacity information and the second adjustment condition corresponding to each of the plurality of storage spaces, configuring part of the space in the shared storage space into the plurality of storage spaces, wherein the part of the space is used for storing service data generated by the plurality of service modules. The data types generated by the plurality of service modules are not identical to the data types generated by the rest of service modules. The remaining service modules may include, for example, an automatic navigation module, an audio-visual entertainment module, and the like. For example, the automatic navigation module may store video data, voice data, vehicle location information, and the like. The video data and the voice data are usually media stream data. Vehicle location information is typically structured data residing in a record or file in fixed fields, and may include longitude, latitude, altitude, vehicle speed, direction, etc.

The size of the shared memory space or the memory space called shared area or shared area can be adjusted. For example, the adjustment may be made according to the storage space of the storage device; the adjustment may also be performed according to the storage space of the storage device, the total storage space corresponding to the plurality of service modules, the remaining storage space information, and the like.

The second adjustment condition may be that a ratio of the plurality of storage spaces to the shared storage space is lower than a ratio threshold, which may be 8:2, for example. The second adjustment condition may be that a ratio of a change amount of the plurality of storage spaces to a change amount of the shared storage space within a predetermined time exceeds a ratio threshold, and the ratio threshold may be 8:2, for example. For example, when the target storage space is switched from the external storage device to the internal storage device, the total storage space becomes smaller, the ratio of the plurality of storage spaces to the shared storage space becomes 5:2, and the ratio is lower than the ratio threshold value 8:2, that is, the second adjustment condition is satisfied. According to the capacity information and the second adjustment condition corresponding to each of the plurality of storage spaces, a part of the space in the shared storage space may be arranged in the plurality of storage spaces. The shared memory space may be used to dynamically increase the multiple memory spaces of multiple business modules. For example, when the traffic data volume of the plurality of storage spaces increases rapidly within the predetermined time, but the shared storage space does not change, the ratio of the amount of change of the plurality of storage spaces to the amount of change of the shared storage space is 10:1, and exceeds the ratio threshold value of 8:2, that is, the second adjustment condition is satisfied, a part of the space in the shared storage space may be configured in the plurality of storage spaces.

In some embodiments, the videos generated by the business module may be divided into emergency videos and non-emergency videos. Non-emergency video may also be understood as cyclic video. For example, the video data with high threat level in the event data recorder and the sentry mode may be urgent video, and the video data with low threat level may be non-urgent video.
