[0018] The present disclosure will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention and are not intended to limit the invention. Additionally, it should be noted that for the sake of description, only parts related to the relevant invention are shown in the drawings.

[0019] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other. The present disclosure will be described in detail below with reference to the drawings and embodiments.

[0020] Figure 1The IoT-based access method of the present disclosure is shown. In an embodiment of the present disclosure, the method includes:

[0021] Step S101, the edge access point encapsulates multiple communication protocols through a communication protocol stack.

[0022] Step S102, the initial data is processed into a standard mode data format through a decoder or an encoder to obtain the data to be transmitted in the standard mode data format.

[0023] Step S103, the data to be transmitted is transmitted through a transmission channel and the encapsulated communication protocol.

[0024] The execution subject of the IoT-based access method in this embodiment can simplify the process of interacting with different protocols by encapsulating these protocols and provide a consistent interface to the upper-layer application. Moreover, the complex underlying details can be hidden, enabling developers to not need to care about the specific implementation details and only need to call the encapsulated API to complete the operation. Once the encapsulation of a certain function is achieved, it can be reused in multiple projects, reducing repetitive labor. Through encapsulation, direct access to certain sensitive operations can be restricted, and only secure operation interfaces are exposed to the outside. Through decoding, it can be ensured that data can be correctly exchanged between different devices and levels.

[0025] Furthermore, to solve the unified access standard and unified output content, the present disclosure designs the concept of an edge access point for accessing terminal devices, and shields the differences through the design of the edge access point for different protocols, different platforms, different manufacturers, different terminal device processing, etc. This improves the visualization of access and the observability of output.

[0026] In addition, the terminal device access platform in the present disclosure has certain protocol standards. For illegal protocols and illegal data formats, the access platform will process them as illegal data, and the access process can also be docked according to the process specified by the platform side.

[0027] In some optional implementation manners of any embodiment of the present disclosure, the encapsulation of the transport communication protocol in the communication transport protocol stack is divided into the implementation of the communication transport protocol stack, the logic of encoding and decoding, and the establishment of a transmission channel. The communication transport protocol stack implements the encapsulation of the protocols defined in the industry (including MQTT, RestFul, etc.). The encoding and decoding logic is mainly responsible for encoding and decoding the data during transmission. Specifically, it can include: encoding Encode from the standard model data into a format recognizable by the device side, and decoding Decode from the device side into the standard model data format. The transmission channel is specifically to construct and bind to an io input-output buffer space with the access platform to achieve data reception and distribution.

[0028] In some alternative implementation manners of any embodiment of the present disclosure, the Internet of Things further includes a server; the server converts the data transmitted by the edge access point according to the format of the standard object model through a processing chain of standard data to obtain converted data, and the converted data supports the standard point position or the standard model format, and the data supporting the standard point position and the standard model format is used for data storage and disk writing.

[0029] Specifically, the server can be set in the cloud, and in some cases, it can also be set in the terminal device.

[0030] The processing chain of standard data (std-processor-chain) is designed to process the specific service model data reported by various terminal devices according to the format of the standard object model, and convert it into data supporting the standard point position data or the standard model format, so as to facilitate the operations of data storage and disk writing.

[0031] Optionally, the server includes multiple data conversion rules corresponding to multiple Internet of Things application scenarios, and different data conversion rules correspond to different service data requirements; the method further includes: the server determines the corresponding data conversion rule according to the service data requirement of the converted data, and uses the data conversion rule to perform data conversion on the converted data.

[0032] Specifically, the processing of the translate-chain on the server side where the platform is located is designed for scenario-based data standard processing. By receiving the standard service model data, that is, the above-mentioned generation of standard point position data and standard format data content, different conversion rules and logics are set to meet the data requirements of the application service. There is a component transformer in the translate-chain that can implement this data conversion process.

[0033] As Figure 2 shown, it shows a schematic flow diagram of data conversion using the component transformer. Among them, the format of the standard product input can be formulated, and the intermediate converter Transformation can be constructed to support the expansion of data scenarios and data quality. In addition, the format and form of scenario-based output can also be formulated, including subscription and alarm, as well as other scenario-based outputs.

[0034] In some alternative implementation manners of any embodiment of the present disclosure, the Internet of Things includes a terminal device and any edge access point, and the method further includes: the terminal device adds an identifier corresponding to the edge access point to the initial data; the initial data and the data to be transmitted include the identifier of the edge access point; the transmitting the data to be transmitted through the transmission channel and the encapsulated target communication protocol includes: any edge access point distributes the data to be transmitted through the transmission channel to the edge access point corresponding to the identifier according to the identifier of the edge access point in the data to be transmitted; if the edge access point corresponding to the identifier is the target edge access point, the target edge access point receives the data to be transmitted.

[0035] Optionally, the distributing the data to be transmitted through the transmission channel to the edge access point corresponding to the identifier includes: determining the edge access point corresponding to the identifier, determining a target instance for receiving data among the edge access points according to at least one of the source area of the data to be transmitted and the terminal function, and distributing the data to be transmitted to the target instance through the transmission channel; the target edge access point receiving the data to be transmitted includes: the target edge access point receiving the data to be transmitted in the target instance.

[0036] For the distribution processing of edge access point data, the data coming up through the communication transmission protocol stack transmission channel needs to carry the identifier of the corresponding edge access point, and the corresponding data is distributed to the specific implementation instances constructed by the corresponding edge access points through the identifier of the edge access point, so as to provide the edge access points with the data logical processing ability.

[0037] The source area can be, for example, the geographical area where the data comes from. The terminal function refers to the function category implemented by the terminal device, such as robot type, lighting type, switch type, and so on.

[0038] In some cases, the method further includes: the target edge access point determines a unified access protocol according to the product type of the terminal device in the target instance, and the unified access protocol includes a standard access protocol or an extended protocol; processing the data to be transmitted through the unified access protocol to obtain a data structure corresponding to the access protocol, so as to generate the data to be transmitted to be uploaded.

[0039] The standard access protocol and the extended protocol can be respectively understood as a standard product model and other extended formats.

[0040] In some alternative implementation manners of any embodiment of the present disclosure, the method further includes: the server generates operation data of the target edge access point, where the operation data includes the response delay time to the server and the data collection time; monitors the operation of the target edge access point through the operation data, and generates response information according to the monitoring result.

[0041] The response information here can be various information such as alarm information.

[0042] In some alternative implementation manners of any embodiment of the present disclosure, the method further includes: the terminal device, in response to the edge access point having been started and running, reads the configuration information of the transmission capacity of the edge access point, where the transmission capacity includes the reporting capacity and the control capacity; constructs a transmission channel between the server and the communication transmission protocol stack as the first channel, a channel for edge access point data distribution as the second channel, and an Internet of Things access platform on the server as the third channel; the terminal device transmits data to the edge access point through the first channel, the second channel, and the third channel.

[0043] In some alternative implementation manners of any embodiment of the present disclosure, the method further includes: the edge access point coordinates and cascades the upload and download of data through the transmission capacity.

[0044] Definition and implementation of the capabilities (data upload and download) of the edge access point. This module is mainly responsible for the configuration of the access point capabilities (reportAbility capability configuration, ctlAbility capability configuration), mainly including the startup and operation parameters of the capabilities, the communication transmission protocol stack transport communication protocol definition of the capabilities, the channel configuration of the capabilities, and the access product configuration of the capabilities. During the startup and operation of the access point, the configuration content will be read, and then a transmission channel for communicating with the communication transmission protocol stack transport, access point data distribution, and a transmission channel with the access platform will be constructed. By binding these three channels and logics, the original data of the device terminal is transmitted into the capabilities (reportAbility capability, ctlAbility capability) of the specific access point, and then specific business processing is performed. This process is the core of the entire edge access point, and realizes the intermediate coordination and cascading process of data upload and data download by abstracting and constructing the reportAbility capability and ctlAbility capability. It is the transfer module in the entire edge access point.

[0045] Such as Figure 3As shown in the figure, the process of layer-by-layer transmission is shown in the direction from the bottom layer to the application layer during the access of the terminal device. Specifically, the rightmost box represents the operation of the communication layer in the edge access point, the middle box represents the operation of the edge access point in the application layer, and the leftmost box represents the operation of the server.

[0046] Among them, as shown in the rightmost box, the transmission channel buffer space can enhance and improve the problem of insufficient edge device resource processing, integrate the computing power of the edge access point, and the codec plug-in for encoding and decoding can expand and maintain the plug-ins that need to perform data format encoding and decoding, and can expand a variety of newly added protocols at the edge device side, and build in the protocols widely used in the industry.

[0047] As shown in the middle box, in the architecture of the edge access point, the unified access standard protocol for a large number of devices solves the problem of the diversity of communication protocols and data formats of terminal devices through various standard protocols and extended protocols built in the edge access point. For the access of complex and massive scenario devices, through the function and area division function of the edge access point, it can conveniently manage the access of terminal devices.

[0048] As shown in the left box, the cloud architecture can quickly and conveniently integrate various operation data of the edge access point, and through the data processing pipeline of Transformer, monitor the response delay time of the edge access point and edge devices and the collected data to optimize the topology of the terminal device and the edge access point.
