Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of data orchestration, and particularly relates to an access authentication and data orchestration method and device based on a visualization technology. BACKGROUND

[0002] When a device accesses an Internet of Things platform, a series of preparation work and configuration need to be performed at the device end, and access authentication is particularly crucial. Since devices of different manufacturers have their own technical characteristics and security requirements, their authentication processes will also differ.

[0003] Most Internet of Things platforms provide an SDK to simplify communication between devices and the platform. When a device needs to access an Internet of Things platform, it initiates a request to the server through the SDK, and the request contains necessary authentication information such as an API key or an access token.

[0004] The SDK is integrated into the firmware of the device, and the following configurations are performed according to the requirements of the platform, including but not limited to: (1) initializing the SDK: initializing the SDK using the API key, access token or other credentials provided by the platform; (2) setting communication parameters: configuring the communication protocol (such as MQTT, COAP, etc.), port, server address, etc.

[0005] The SDK provided by cloud service providers and the SDK development method for specific protocols (such as MQTT, COAP, UDP and HTTP, etc.) in the prior art need to be completed through programming languages (such as Java, Python, C++, Node.JS, etc.). The method of using the SDK plug-in provided by the cloud service provider may cause a high dependence on a certain platform or service, thereby limiting future flexibility. If multiple operating systems or hardware platforms need to be supported, the integration of the SDK may become very complex, and the SDK development also needs a certain amount of time to learn its API and working principle, which requires more human and time resources.

[0006] When device data accesses an upper Internet of Things platform or different SAAS applications, it may be necessary to unify the data into a standard format for data collection and unified management, or to distribute the data in a specific format to different SAAS applications to meet their business logic or performance requirements.

[0007] The current method device or the Internet of Things platform provides an SDK library or uses a special software or hardware gateway to receive data from different devices and convert the data into a standard format supported by the Internet of Things platform. The above method of introducing a protocol gateway or an SDK to convert the data format will result in a large number of device data message formats as the number of customers increases and custom data formats. At the same time, due to the large number of data protocols, the difficulty and cost of device firmware version maintenance, logistics storage and order management are greatly increased, and the overall complexity is increased, that is, there are problems of protocol incompatibility, data format diversity, complex access authentication process and the like. These problems result in high device development and access costs and great difficulty in subsequent maintenance.

[0008] Therefore, the application provides an access authentication and data arrangement method and device based on a visualization technology to solve the above technical problems. SUMMARY

[0069] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0070] In the embodiments, refer to Figures 1 to 7 .

[0071] In the prior art, referring to Figure 7 , when a device accesses an Internet of Things platform, a series of preparation work and configuration need to be performed at the device end, and access authentication is particularly critical. A conventional Internet of Things platform provides an SDK to simplify the communication between the device and the platform. When the device needs to access the Internet of Things platform, it initiates a request to the server through the SDK, and the request contains necessary authentication information such as an API key or an access token. The SDK is integrated into the firmware of the device, and the following configurations are performed according to the requirements of the platform, including but not limited to: (1) initializing the SDK: initializing the SDK using the API key, access token or other credentials provided by the platform; (2) setting communication parameters: configuring the communication protocol (such as MQTT, COAP, etc.), port, server address, etc. At this time, the device accessing the Internet of Things platform or SAAS application has problems such as protocol incompatibility, data format diversity, and complex access authentication process. These problems lead to high cost of device development and access, and great difficulty in subsequent maintenance.

[0072] Therefore, as shown in Figure 2 , the embodiments of the present application propose an access authentication and data arrangement method based on visual technology to realize the authentication operation and unified data format arrangement operation of the generic protocol device accessing the Internet of Things platform or SAAS application. The method uses field tree mapping and visual diagramming through an intermediate device without the need to write code, thereby greatly improving the efficiency of data processing. This method not only reduces the development cost, but also enables non-technical personnel to easily manage and adjust the authentication strategy and data structure of the system, thereby enhancing the usability and flexibility of the entire solution, as shown in Figure 1 and Figure 3 , the method specifically includes:

[0073] (1) implement an authentication access strategy to obtain device data that passes authentication;

[0074] The specific implementation steps of the authentication access strategy include:

[0075] S1. In the Internet of Things platform, register the device using the device number (device ID, device code, or IMEI number, etc. on the device side), and the Internet of Things platform automatically generates a unique ID for the Internet of Things authentication device and the corresponding key based on the provided device code in combination with the product ID of the Internet of Things platform;

[0076] S2. Import the corresponding file generated by the Internet of Things platform, which contains device number, Internet of Things ID, and key information, into the intermediate device, and based on the corresponding file generated by the Internet of Things platform, establish an authentication mapping relationship between the device number of the device itself and the Internet of Things ID, as shown in Figure 4

[0077] S3. Determine the device access method, including device direct connection and platform access, wherein: device direct connection uses the device to directly report the collected data to the intermediate device; platform access configures authentication information such as platform account, password, and Internet of Things key token in the intermediate device, which is used to verify the identity of the device and its access rights, and realizes data transmission between the device and the device through a defined interface;

[0078] S4. Whether using device direct connection or platform access, all device data will be stored in a unified device data pool, and the data pool serves as a centralized data storage and processing unit for receiving, integrating, and managing information sent from devices accessed from various channels;

[0079] At this time, it needs to be supplemented that in the device direct connection state, the data is directly reported by the device to the data pool; in the platform access state, the data is first verified by the configured authentication information (such as account, password, and Internet of Things key token, etc.) to verify the identity of the device, and then securely transmitted to the data pool through a specific interface;

[0080] S5. In the device data pool, retrieve the device data that has been registered and mapped according to the device number, and then use the device ID and Internet of Things key token to complete the authentication process;

[0081] In summary, by setting the authentication access strategy in the intermediate device, the mapping relationship between the device number and the Internet of Things device ID can be established, thereby achieving fast and non-sensing access of the device or platform without modifying the device firmware, and further completing seamless connection with various Internet of Things platforms and SAAS applications; ​

[0082] (2) Source data format to target data format visualization arrangement conversion for different structure data;

[0083] The specific execution steps of the visualization arrangement operation include:

[0084] L1. Receive authenticated device (source) data, including XML, key-value pair, hexadecimal, and JSON formats;

[0085] L2. Determine whether the device data is connected to the Internet of Things platform, and perform different processing methods on the data source. At this time, there are two processing methods for the data source, specifically including:

[0086] a1. For device data that needs to be connected to the Internet of Things platform, use the visualization data format arrangement function of the intermediate device to convert different data format standards to JSON format, and upload it to the Internet of Things platform through MQTT;

[0087] a2. For data that needs to be distributed to different SAAS applications, use the visualization data format device to parse and arrange the device data, and then use the data distribution tool to distribute the special data format required by different customers to different customers;

[0088] L3. Use the intermediate device to configure the data format arrangement process by dragging and dropping nodes to arrange the data format and clean the data;

[0089] Taking XML and hexadecimal to JSON as an example, the data format arrangement and data cleaning include:

[0090] b1. First, perform XML to JSON arrangement conversion node configuration operation in field tree connection mode;

[0091] The specific operation process includes:

[0092] b101. Build a data arrangement process by dragging and connecting nodes, start node pushes device source data to the conversion node, and end node pushes data through MQTT protocol;

[0093] b102. Configure the conversion node. In the data format arrangement conversion node, select the input type as XML stream and the output type as JSON stream;

[0094] b103. Refer to Figure 5 , import XML source field tree text and JSON target field tree text, and use the intermediate device to parse and recognize XML and JSON data text into field tree graph according to the key / value values of the text;

[0095] b104. Refer to Figure 6The field that needs to set the mapping relationship is connected, and the value mapping of the source field and the target field is completed.

[0096] It can be further explained at this time that in addition to connection mapping, the following operations can be performed on the field during the XML to JSON conversion arrangement conversion node configuration operation process in the field tree connection mode:

[0097] (a) Field transmission: used to determine whether the field needs to be transmitted according to the parameter content;

[0098] (b) Encryption and decryption: used to determine whether encryption and decryption are needed, and the parameter value is 1, then encryption is needed, and the parameter value is -1, then decryption is needed;

[0099] (c) Set global variable: used to set the field as a global variable;

[0100] (d) Get global variable: used to set the function parameter as a global variable name;

[0101] (e) Static value: no source field is needed to directly set a fixed value to the target field;

[0102] (f) Timestamp: no source field is needed to directly generate a timestamp for the target field;

[0103] (g) Value judgment: size judgment is performed according to the input value;

[0104] (h) Parameter merging: used to merge multiple parameters into one, so as to merge the fields set as global variables.

[0105] In addition, it can be explained that the same operation steps can also be used to complete the data format conversion between XML to JSON, JSON to JSON, XML to Key Value, XML to tuxedo, and other data formats;

[0106] b2. Then perform the hexadecimal to JSON operation in a visual diagram;

[0107] The specific operation process includes:

[0108] Drag and connect the nodes to build a data parsing process, at this time, use the parsing node to perform the hexadecimal to JSON operation step;

[0109] In the parsing node, the execution method and the parsing method will be encapsulated into a puzzle-like module. First, according to the target data format, drag the graphical module to build the JSON data structure, and then embed the parsing method modules such as string interception and hexadecimal to decimal conversion into the execution module. The source data string can be located and intercepted, the hexadecimal to decimal parsing method can be executed, and the module parameters can be filled in to customize the target field name.

[0110] (3) After the authentication and the source data format to the target data format are arranged and converted, the device ID is written into the Client Id field of the MQTT message, the token key is written into the device Password field, and data pushing is initiated to the Internet of Things platform or the SAAS application through the standard MQTT protocol message format, and specific data format customization is realized for the corresponding SAAS application according to the specific needs of different customers.

[0111] Therefore, by integrating the authentication access strategy and the data arrangement conversion function in the intermediate device, the development process can be simplified and the system security can be improved, thereby reducing the development cost and the maintenance cost, and further an efficient, safe and easy-to-manage Internet of Things solution can be provided.

[0112] Meanwhile, since the authentication access strategy and the visual arrangement conversion are both realized based on the intermediate device, the intermediate device operates as an intermediate layer between the device and each Internet of Things platform, and therefore on the other hand, the application also discloses an access authentication and data arrangement device based on a visual technology, which is used as an intermediate device to execute the access authentication and data arrangement method based on the visual technology disclosed in the above embodiments, and the device is internally provided with a system as shown in Figure 2 for executing corresponding access authentication and data arrangement operations, including:

[0113] An authentication access strategy is used to establish a mapping relationship between the device number and the Internet of Things device ID, and to bind the authentication information of the device with the authentication information required for accessing the Internet of Things platform.

[0114] A business arrangement, analysis and storage module is used to arrange, analyze and store the data of the accessed device, and the device data in different communication protocols are uniformly arranged and converted into a standard format, so as to facilitate smooth access to the Internet of Things platform.

[0115] A data format customization module is used to customize the data into a specific format to meet the needs of different upper-layer applications, and in the data format customization module, a visual data arrangement method is used to flexibly analyze and convert the data format, so as to meet the specific needs of different business applications of the upper layer, improve the adaptability of the system and the customer satisfaction.

[0116] In addition, as an intermediate layer of the device and the platform, the device actively adapts to various device protocols (such as TCP, UDP, HTTP and LwM2M, etc.), and through the visual interface operation, the device developer or the end user can complete the adaptation and access of the device through simple dragging and selection of parameters, and the whole process does not require any code writing or SDK installation on the device side.

[0117] Therefore, by supporting data access, parsing and arrangement of multiple communication protocols (such as TCP, UDP, HTTP and LwM2M) in the service arrangement, parsing and storage module, the mutual conversion between heterogeneous source data and platform standard format data can be realized, so as to improve the data processing flexibility and compatibility, and meet the access requirements of different devices and platforms.

[0118] Therefore, the device of the present application can actively adapt to different authentication modes of devices, process authentication requirements in the device access process, and ensure the non-inductive connection between devices and the Internet of Things platform and SAAS application.

[0119] In addition, the visual arrangement data format is also supported, which simplifies the data processing method and further improves the convenience and efficiency of device access.
