[0027] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0028] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0029] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0030] The term "multiple" as used in this application refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0031] The degree of refinement of vehicle DVR data management under related technologies is low. When accessing data, the full amount of data is usually loaded from the media library. It is impossible to access and obtain data according to different access rights. There are problems of data leakage and misoperation, which reduces the security of the vehicle DVR system.

[0032] To this end, one aspect of the present application provides a DVR data management method. Figure 1 , Figure 1 1 is a flowchart of a DVR data management method shown in an exemplary embodiment of the present application. The management method at least includes S110 to S140, which are described in detail as follows:

[0033] S110: In response to the access request, determine the data access rights of the current login account according to the identity identifier of the current login account.

[0034] In an optional embodiment, it may be a passive access request that is automatically triggered after a user logs into an account. After the executing subject of this embodiment (this application) obtains the current login information, it automatically enters the access process for the data corresponding to the current login account, which is conducive to quickly responding to the user's subsequent data operation requests.

[0035] In another optional embodiment, the access request may also be an active access request triggered by a user, which is used to specifically access a certain type or item of data.

[0036] In this application, data access rights refer to rights for different accounts to access different ranges of data in the vehicle DVR media library. In some embodiments, a mapping relationship is established between the rights and the corresponding accounts, that is, different accounts have different data access rights.

[0037] S120: Based on the data access rights, determine the data set corresponding to the current login account, and obtain the data in the data set and save it in the cache area.

[0038] There is an inclusion relationship between data sets corresponding to different levels of data access permissions.

[0039] In this application, the data set corresponding to the high-level data access permission includes the data set corresponding to the low-level data access permission. Among them, the level of data access permission is a relative concept determined by relevant technical personnel in combination with actual scenarios. Generally, the higher the level of data access permission, the larger the range of accessible data.

[0040] Exemplarily, if the data access permission of the current login account is the lowest, the corresponding data set only includes data generated under the current login account; if the data access permission of the current login account is the highest, the corresponding data set also includes data generated under other lower-level accounts.

[0041] S130: In response to the operation request, according to the operation type specified by the operation request, a corresponding data operation is performed on the buffer area to output the buffer area data after the operation.

[0042] Among them, the operation type includes at least a query type and a modification type. In this application, the operation type may also include a sorting type, a compression type, an indexing type, etc. that are commonly used in practical applications, and this application does not impose any restrictions on this.

[0043] The operation request is actively proposed by the user, usually for querying or modifying certain data. After receiving the operation request, the corresponding data operation is performed on the cache area according to the specified operation type, and the data after the operation is output, thereby completing data management and page interaction.

[0044] This embodiment allocates different data access rights to different accounts, restricts different users' access to and operation of DVR data, implements DVR data classification management, avoids data leakage and misoperation, and improves the security of the DVR system. By saving the data set corresponding to the current login account to the cache area, receiving the user's operation request, and performing corresponding data operations on the cache area according to the corresponding operation type, the data loading and processing speed can be improved, and the user experience can be improved.

[0045] In another exemplary embodiment of the present application, based on the above Figure 1 The management method shown illustrates how to determine the data access rights of the current login account. The specific steps include S1101-S1103, which are described in detail as follows:

[0046] S1101: If the identity identifier of the current login account has an index relationship with the identity identifiers of other accounts, and the identity identifier of the current login account is the parent node in the index relationship, then the data access permission of the current login account is the first-level access permission.

[0047] In this application, the accounts of car DVR users are divided into three categories. The first category is the car owner account, the second category is the authorized account authorized by the car owner account, and the third category is the unauthorized visitor account. Among them, there is only one car owner account and one visitor account respectively, but there can be multiple authorized accounts.

[0048] In order to facilitate the management of authorized accounts by the car owner account, an index relationship will be established between the car owner account and the authorized accounts. The car owner account is the parent node of multiple authorized accounts, and correspondingly, each authorized account is the child node of the car owner account. The tourist account is a temporary account. In order to save the management overhead of the tourist account and to preserve the temporary nature of the tourist account, the tourist account is generally not associated with other accounts, but is independent of other accounts.

[0049] For example, Figure 2 As shown, Figure 2 This is a diagram showing the relationship between the identity identifiers of multiple accounts. If the identity identifier of the current login account is 10000417, Figure 2It can be seen that 10000417 has an index relationship with the identity identifiers of multiple other accounts, and 10000417 is the parent node in the index relationship. Therefore, it is determined that the data access permission of the current login account is the first-level access permission.

[0050] It is understandable that in actual applications, the car owner account should have the highest access rights, and 10000417 is the identity identifier of the car owner account.

[0051] S1102: If the identity identifier of the current login account has an index relationship with the identity identifiers of other accounts, and the identity identifier of the current login account is a child node in the index relationship, then the data access permission of the current login account is a secondary access permission.

[0052] For example, in combination Figure 2 As shown, if the identity identifier of the current login account is 10000519, it has an index relationship with 10000417, and 10000519 is a child node in the index relationship. Therefore, it is determined that the data access permission of the current login account is a secondary access permission.

[0053] In actual applications, the authorization account authorized by the car owner should have authority second only to the car owner, and 10000519 is the identity identifier of the authorized account.

[0054] Similarly, 10000518, 10000520, etc., which are similar to 10000519, are the identity identifiers of other authorized accounts.

[0055] S1103: If there is no index relationship between the identity identifier of the current login account and the identity identifiers of other accounts, the data access permission of the current login account is the third-level access permission.

[0056] For example, in combination Figure 2 As shown, if the identity identifier of the current login account is Guest, there is no index relationship with the identity identifiers of other accounts. Therefore, it is determined that the data access permission of the current login account is the third-level access permission.

[0057] In actual applications, unauthorized guest accounts have the lowest permissions, and Guest is the identity identifier of the guest account.

[0058] The data set corresponding to the first-level access permission includes the data set corresponding to the second-level access permission, and the data set corresponding to the second-level access permission includes the data set corresponding to the third-level access permission.

[0059] For example, see Figure 3 , Figure 3It is a schematic diagram of the inclusion relationship between the data sets corresponding to different accounts, where the data set accessible to the owner account includes data under the directory of the owner account itself, as well as data under all authorized account directories and visitor account directories; the data set accessible to the authorized account includes data under the directory of the authorized account itself and data under the directory of the visitor account, while the data set accessible to the visitor account only includes data under the directory of the visitor account itself.

[0060] In this application, the data access permissions of multiple authorized accounts are all second-level access permissions, and each account cannot access the data under the other account, thereby ensuring the data privacy and security of different authorized accounts.

[0061] This embodiment provides a method for determining the data access rights of the current login account based on the identity identifier of the current login account. By judging whether there is an index relationship between the identity identifiers of multiple accounts and the node positions in the index relationship, the data access rights are determined, thereby conveniently and quickly realizing differentiated management of different accounts and providing a basis for classified management of DVR data.

[0062] In another exemplary embodiment of the present application, based on the above Figure 1 The management method shown in the figure illustrates how to determine the data set corresponding to the current login account, and obtain the data in the data set and save it in the cache area. The specific steps include S1201-S1203, which are described in detail as follows:

[0063] S1201: If the access request does not carry any associated information, all data in the data set corresponding to the current login account are saved in the cache area.

[0064] If the access request does not carry any associated information, it indicates that the current access request is a passive access request automatically triggered after the user logs into the account. At this time, all data in the data set corresponding to the current login account is saved in the cache area.

[0065] Exemplarily, when a user logs into a vehicle owner account and does not actively request access to a certain category or item of data, all accessible data under the vehicle owner account will be automatically saved to the cache area, including the vehicle owner account, various authorized accounts, and data generated by the visitor account.

[0066] S1202: If the access request carries the target data type, the data belonging to the target data type in the data set corresponding to the current login account is saved in the cache area.

[0067] If the access request carries the target data type, it indicates that the current access request is an active access request triggered by the user, which is used to access a certain type of data in a targeted manner. At this time, the data belonging to the target data type in the data set corresponding to the current login account is saved in the cache area.

[0068] In this application, the vehicle-mounted DVR is taken as a driving recorder as an example, and the data types include: loop video, emergency video and picture.

[0069] Exemplarily, when a user logs in to authorized account 1 with the identity ID 10000518 and actively requests access to looping video data, the data belonging to the looping video type in the data set accessible under authorized account 1 is saved to the cache area, specifically including the looping video data generated by authorized account 1 and the visitor account.

[0070] An example access path is:

[0071] pathMap.put(10000518,"DVR root path / SeresDVR / RecordLoop / 10000518","DVR root path / SeresDVR / RecordLoop / Guest"])

[0072] Among them, RecordLoop represents the loop video.

[0073] S1203: If the access request carries a target date, the data corresponding to the timestamp that matches the target date in the data set corresponding to the current login account is saved in the cache area.

[0074] If the access request carries a target date, it indicates that the current access request is an active access request triggered by the user, which is used to access one or more data in a targeted manner. At this time, the data with the corresponding timestamp that meets the target date in the data set corresponding to the current login account is saved in the cache area.

[0075] Exemplarily, a user logs in to a guest account with the identity of Guest, and actively requests to access data with a date of 2012.12.21, and saves the data with a date of 2012.12.21 under the guest account to the cache area.

[0076] An example access path is:

[0077] pathMap.put(Guest,"DVR root path / SeresDVR / Guest / 2012.12.21"])

[0078] In an optional embodiment, the access request may carry both the target data type and the target date, or other applicable associated information for filtering data, which is not limited in the present application.

[0079] This embodiment provides a method for determining the data set corresponding to the current login account and obtaining the data in the data set and saving it to the cache area. The basic data set is determined through the data access rights of the current login account, and the associated information carried in the access request for filtering data is combined to determine the data that ultimately needs to be cached, thereby achieving secure and personalized management of DVR data.

[0080] This embodiment monitors the media library data and updates the data stored in the buffer area in real time, thereby improving the intelligence of the vehicle DVR data management and the user's access experience.

[0081] In another exemplary embodiment of the present application, based on the above Figure 1 The management method shown also explains how to perform corresponding data operations on the buffer area according to the operation type specified by the operation request to output the buffer area data after the operation, that is, S130 also includes S310-S330, which are described in detail as follows:

[0082] S310: If the operation type specified by the operation request is a query type, the target data in the buffer area is output.

[0083] The target data is determined according to the target resource identifier.

[0084] In the present application, the operation request actively proposed by the user carries a target resource identifier, which is used to represent the target data that needs to be operated. Since the data in the cache area is copied from the data in the media library, the same data in the media library and the cache area have the same resource identifier.

[0085] For example, the user submits an operation request with a URI of / images / pic.jpg and a flags value of 04, that is, a query operation is performed on a piece of image data, then the image data is directly called from the cache area to realize page display of the image data.

[0086] Among them, URI is the target resource identifier in this application, and its format is only an example. The same applies to the following, and this application does not limit this. Flags is used to represent the operation type. In this application, there are four states: 01, 02, 03, and 04, which represent add, delete, update, and query respectively.

[0087] S320: If the operation type specified by the operation request is addition or update in the modification type, the target data is obtained from the media library based on the target resource identifier, the data in the buffer area is modified, and the modified buffer area data is output.

[0088] For example, a user submits an operation request with a URI of / videos / movie.mp4 and flags of 01 or 03, i.e., to add or update a video data. First, a modification operation is performed on the target data located by the URI in the media library. Then, based on the modified target data in the media library, the target data located by the URI in the cache is modified, and the modified target data is output.

[0089] S330: If the operation type specified by the operation request is deletion in the modification type, the target data in the cache area is deleted, and the cache area data after deletion is output.

[0090] For example, the user makes an operation request with URI / videos / movie.mp4 and flags 02, that is, to delete a video data. Then, the target data located by the URI in the media library is deleted first, and then the target data located by the URI in the cache is deleted, and the cache data after deletion is output.

[0091] In another exemplary embodiment of the present application, based on the above Figure 1 The management method shown in the figure illustrates how to obtain target data from the media library based on the target resource identifier and modify the data in the cache area, that is, S320 includes S3201 to S3202, which are described in detail as follows:

[0092] S3201: If the operation type specified by the operation request is addition in the modification type, target data is obtained from the media library based on the target resource identifier and added to the cache area, and the added cache area data is output.

[0093] For example, the user makes an operation request with URI / videos / movie1.mp4 and flags 01, that is, to add a video data. First, the target data is generated at the corresponding position in the media library and a URI is assigned to it. Then, the target data is located and obtained through the URI, added to the cache area, and the added target data is output.

[0094] S3202: If the operation type specified by the operation request is update in the modification type, the target data is obtained from the media library based on the target resource identifier, the data in the cache is updated, and the updated cache data is output.

[0095] For example, a user submits an operation request with a URI of / videos / movie2.mp4 and flags of 03, i.e., an update operation is performed on a video data, for example, the type of the video data is changed to a picture type. Then, a corresponding update operation is performed on the target data located by the URI in the media library, and then based on the updated target data in the media library, the target data located by the URI in the cache is updated, and the updated target data is output.

[0096] This embodiment locates and operates the target data through the target resource identifier and the operation type, quickly responds to the operation request put forward by the user, and updates the page by refreshing the cache, which is beneficial to the real-time operation of the user and improves the convenience of data management.

[0097] In another exemplary embodiment of the present application, another DVR data management method is provided, which specifically includes: if the data in the media library is updated, then based on the updated data in the media library, the data in the cache area is updated.

[0098] In this application, in addition to receiving operation requests for DVR data actively proposed by users, the data in the media library will also be monitored. If the data in the vehicle DVR media library changes, the data object will be accurately located and the corresponding change operation will be synchronously updated to the cache area to achieve unified data management.

[0099] For example, when a user logs in to the car owner account to access all data, the car DVR works synchronously and may generate new pictures and save them in the media library. If it is detected that a new picture data is added to the media library, in order to ensure that the data accessed by the user is not missed, the picture data is saved in the cache area through the resource identifier of the new picture data.

[0100] The specific method for updating the data in the cache area based on the updated data in the media library is the same as the steps in responding to the user's operation request, please refer to the above description.

[0101] In another exemplary embodiment of the present application, another DVR data management method is provided, which specifically includes: classifying multiple data according to the data types corresponding to each of the multiple data, and associating them with the identity identifiers of the corresponding accounts to generate data sets corresponding to each of the multiple accounts.

[0102] Exemplarily, before responding to access requests and operation requests, the data generated under each account in the vehicle DVR is classified according to the data type, and associated with the identity identifier of the corresponding account, and persistently stored and managed in the form of key-value pairs, so that data sets can be determined for different accounts based on their corresponding data access permissions, thereby realizing personalized data management based on the account.

[0103] This embodiment specifically describes how to classify and manage DVR data according to different accounts, and assign different data access rights to different accounts to avoid data leakage and misoperation, thereby ensuring data security. The data is saved in the cache area, and when the user's operation request is received, the data in the cache area is updated and output in real time to quickly respond to the user's operation, thereby improving the convenience of data management and interactive experience.

[0104] See also Figure 4 , Figure 4 FIG. 1 is a flow chart of another DVR data management method according to an exemplary embodiment of the present application. The detailed description is as follows:

[0105] First, the identity of the login account is obtained, and the looping video, emergency video and picture in the data set corresponding to the current login account are accessed. In order to reduce unnecessary processes, during the access process, it is determined whether the various types of data in the current account directory have generated physical files. If not, an error message is directly prompted and data management is exited. If the physical file has been generated, all types of data are saved in the cache area, and then the cached data is operated according to the user's operation request to add data, delete data, update data or query data, and finally the cached data is output.
