Description

Technical Field

[0001] This application relates to the field of data access technology, specifically to a data access method, apparatus, device, and storage medium based on the Industrial Internet of Things. Background Technology

[0002] The IoT operational architecture comprises the IoT information architecture, physical architecture, and functional architecture. The functional architecture, in particular, is the external functional manifestation of the information system supported by the physical system. It presents a five-platform structure, including the user platform, service platform, management platform, sensor network platform, and object platform. These correspond to the user domain, service domain, sensor domain, and object domain in the information architecture, and the user layer, service layer, management layer, sensor network layer, and object layer in the physical architecture, respectively.

[0003] Due to the explosive growth of data volume, the traditional five-platform architecture reduces the user experience during data access. For example, the centralized management of large amounts of data leads to low operating efficiency and the platform is prone to crashing. In this case, user access verification is restricted, identity verification often gets stuck, and users may be unable to access the platform or some unauthorized users may be authorized to access it, resulting in a significant reduction in the user experience of data access interaction.

[0026] In response to an access request initiated by a target user on the user platform, the target user is authenticated on the management sub-platform to confirm that the target user has access rights to the object sub-platform bound to the management sub-platform and to obtain the authentication result.

[0036] Compared with the prior art, the beneficial effects of this application are:

[0037] This application provides a data access method, apparatus, device, and storage medium based on the Industrial Internet of Things (IIoT). The method includes: responding to an access request initiated by a target user on a user platform, determining a target object sub-platform and a target service sub-platform; transmitting target data stored in a sub-database corresponding to the target object sub-platform to a first master database via its sensor network sub-platform; transmitting the received target data from the first master database to a sub-database corresponding to the target service sub-platform via a second master database; determining accessible data in the target data according to the target user's data access permissions, and authorizing the accessible data to the user platform for access by the target user through a third master database.

[0047] See attached document Figure 2Based on the hardware devices of the foregoing embodiments, embodiments of this application provide a data access method based on the Industrial Internet of Things (IIoT), applied to the IIoT. The IIoT includes a user platform, a service platform, a management platform, a sensor network platform, and an object platform. The object platform includes several object sub-platforms, which are used to collect data fed back by different sensor objects. The sensor network platform includes a first overall database and several sensor network sub-platforms. Each of the several sensor network sub-platforms is configured with a sub-database, which is used to store data collected by an object sub-platform. The several sensor network sub-platforms interact with the first overall database. The management platform includes a second overall database, which interacts with the first overall database. The service platform includes a third overall database, several sub-databases, and several service sub-platforms. The third overall database interacts with the user platform. The third overall database interacts with the second overall database through the sub-databases. The several sub-databases interact with a service sub-platform. The method includes the following steps:

[0048] S10: In response to an access request initiated by a target user on a user platform, determine the target object sub-platform and the target service sub-platform.

[0049] In practice, the target user is the user who initiates the access request through the user platform, which can be a device such as a mobile phone or computer. The user's access request directly specifies the object or service to be accessed. For example, the object platform may have several physical devices connected via sensors, and the user's request may only access data from one or more of them, such as accessing the operating data of a smart water meter or a motor. The services accessed are the various services that the operator can provide to the user, such as maintenance services or inspection services.

[0050] In one embodiment, in response to an access request initiated by a target user on a user platform, determining the target object sub-platform and the target service sub-platform includes:

[0051] In response to an access request initiated by a target user on the user platform, the system authenticates the target user and obtains the authentication result.

[0052] Based on the authentication result, obtain the target user's accessible objects and services;

[0053] Within the accessible objects and accessible services, the target object sub-platform and the target service sub-platform are determined respectively.

[0054] In the specific implementation process, in order to improve the security of data access, after a user initiates an access request, their identity is verified. Verifying identity is actually to verify which objects and services the user has access permissions to. These permissions are granted by the IoT platform. Some users may not be aware of their own permissions, so identity verification is required to verify whether the object in their request is one they can access, thereby determining the target object sub-platform and the target service sub-platform.

[0055] In one embodiment, the management platform further includes several management sub-platforms, each management sub-platform being bound to an object sub-platform. All management sub-platforms interact with the second central data platform, responding to an access request initiated by a target user on the user platform, authenticating the target user, and obtaining the authentication result, including:

[0056] In response to an access request initiated by a target user on the user platform, the target user is authenticated on the management sub-platform to confirm that the target user has access rights to the object sub-platform bound to the management sub-platform and to obtain the authentication result.

[0057] In practice, identity verification is usually performed on the management platform. However, in order to improve the efficiency of identity verification and avoid the verification process from occupying the management platform's resources for a long time, the management platform is configured as multiple sub-platforms. Each management sub-platform is bound to an object sub-platform. That is, one management sub-platform is used to verify whether the user has access rights to the bound object sub-platform. In this way, even when faced with many access requests and many access objects, the verification work can be distributed to the sub-platforms, which greatly improves the efficiency of verification.

[0058] S20: The target data stored in the sub-database corresponding to the target object sub-platform is transmitted to the first general database via the sensor network sub-platform where it is located.

[0059] In the specific implementation process, after identifying the target object, i.e., the target object sub-platform, the target data stored in its corresponding sub-database is first transmitted to the first main database through the sensor sub-platform. Since the sensor network platform is configured as multiple sub-platforms, data transmission does not need to occupy the main channel every time. The data of each object sub-platform is transmitted through its corresponding sensor network sub-platform, effectively alleviating the data transmission pressure of the platform under big data.

[0060] To achieve accurate and rapid retrieval and transmission of stored data, each object sub-platform is connected to a physical device for integration into the Industrial Internet of Things (IIoT). The physical device feeds back data via sensors, and the object sub-platform collects the data from different sensor objects. Data from each physical device is stored in a sub-database. In other words, before transmitting the target data stored in the sub-database corresponding to the target object sub-platform to the first overall database via its respective sensor network sub-platform, the method further includes:

[0061] Data collected from different sensing objects by several object sub-platforms are stored in separate databases.

[0062] Furthermore, after storing the data collected from different sensing objects by several object sub-platforms into separate databases, the method also includes:

[0063] The data in the sub-database is classified to obtain the target sub-database.

[0064] In the specific implementation process, when establishing a sub-database, data can be classified and stored according to different data types. That is, different storage spaces are divided within the sub-database to store different types of data. The data classification criteria can be based on the data type collected, such as image data and video data. The classified sub-database is the target sub-database.

[0065] Based on the aforementioned steps, the target data stored in the sub-database corresponding to the target object sub-platform is transmitted to the first general database via the sensor network sub-platform where it resides, including:

[0066] The target data stored in the target sub-database corresponding to the target object sub-platform is transmitted to the first general database via the sensor network sub-platform where it is located.

[0067] S30: The received target data is transmitted from the first general database to the sub-database corresponding to the target service sub-platform via the second general database.

[0068] In the specific implementation process, after the target data is determined, the target data is transferred to the second main database through direct data transfer between the first and second databases. Then, according to the location of the target service sub-platform, the data is transferred purposefully to the corresponding sub-database, thereby improving the efficiency of interactive access.

[0069] S40: Based on the target user's data access permissions, determine the accessible data in the target data, and authorize the accessible data to the user platform through a third-party general database for the target user to access.

[0070] In the specific implementation process, after the target data is pushed, in order to ensure the security of data access, the accessible data in the target data will be filtered according to the user's data access permissions. The reason for confirming the target data on the service platform after it is finally received is that confirmation also requires computing resources. This can reduce the computing pressure on the previous platforms. In addition, if the data changes, it may affect the correspondence of the previous platforms. Therefore, it is placed on the last platform for data feedback to the user.

[0071] In this embodiment, by analyzing the access requests initiated by users, the objects and services that users can access are directly determined. Then, through the target object sub-platform, the corresponding data is transmitted layer by layer to the sub-database of the service platform sub-platform. Finally, based on the user's data access permissions, the accessible portion of the transmitted data is pushed to the user for access, thereby improving interaction security. Furthermore, since the access request is directly matched with the collected object, accurate data access push can be achieved. At the same time, the data is stored separately on the sensor network platform according to different objects, which not only ensures the orderly management of data on the sensor network platform, but also reduces the operational pressure on the management platform, thereby improving the efficiency of data access, making the access process clearer, and enhancing the user experience.

[0072] In one embodiment, after storing the data collected from different sensing objects by several object sub-platforms into a separate database, the method further includes:

[0073] Access permissions are categorized for the data collected from different sensor objects, and these access permission categories are then linked to the user's data access permission level.

[0074] In practical implementation, to achieve more efficient data access, access permissions are tiered immediately after data collection. For example, within the same object's collected data, some data is more confidential and requires higher access permissions, while other data is general and can be accessed with normal permissions. Simultaneously, the tiered data access permissions are linked to the user's data access permission level. This allows for faster and more accurate determination of which levels of data a user can access, achieving high-efficiency push notifications. Once the user's data access permission level is determined, matching the data at the corresponding level confirms that this data is accessible within the target data set. In other words: based on the target user's data access permissions, the accessible data within the target data set is determined, including:

[0075] Based on the target user's data access permission level, match data at the target level to determine the accessible data within the target data.

[0076] The framework for the Industrial Internet of Things (IIoT) in application scenarios provided in this application embodiment is attached. Figure 3 As shown, the system can include a user platform, a service platform, a management platform, a sensor network platform, and an object platform. The physical entities of the user platform include various user terminals, such as mobile phones, computers, and dedicated terminals, which, through integration with user information system software, provide services to the user end. The service platform is user-facing and independent of the management platform, and also provides user service demand calculations to form a service-related database. The management platform is the overall operation and coordination platform for the Internet of Things (IoT), including various management sub-platforms and a data center. Different management sub-platforms execute different management tasks, and the data center stores various types of management data. The sensor network platform provides functions such as data communication, transmission, parsing, identification, and classification, avoiding the direct aggregation of data from various object platforms onto the management platform, which would result in data redundancy and low data processing efficiency. The object platform, based on user-perceived service needs, senses and provides corresponding information to the user.

[0077] Based on the same inventive concept as in the foregoing embodiments, this application also provides a data access device based on the Industrial Internet of Things (IIoT), applied to the IIoT. The IIoT includes a user platform, a service platform, a management platform, a sensor network platform, and an object platform. The object platform includes several object sub-platforms, which are used to collect data fed back by different sensor objects. The sensor network platform includes a first overall database and several sensor network sub-platforms. Each of the several sensor network sub-platforms is configured with a sub-database, which is used to store data collected by one object sub-platform. The several sensor network sub-platforms interact with the first overall database. The management platform includes a second overall database, which interacts with the first overall database. The service platform includes a third overall database, several sub-databases, and several service sub-platforms. The third overall database interacts with the user platform. The third overall database interacts with the second overall database through the sub-databases. The several sub-databases interact with a service sub-platform. The device includes:

[0078] The request module is used to respond to access requests initiated by target users on the user platform and to determine the target object sub-platform and the target service sub-platform.

[0079] The first transmission module is used to transmit the target data stored in the sub-database corresponding to the target object sub-platform to the first general database via the sensor network sub-platform where it is located.

[0080] The second transmission module is used to transmit the received target data from the first general database to the sub-database corresponding to the target service sub-platform via the second general database.
