Description
TECHNICAL FIELD Ill The present disclosure relates to the field of Internet of Things (IoT), and specifically, to an edge computing-based IoT proxy apparatus and data decision-making method.
[2] Mainly used in local areas, a wireless sensor network cannot implement network-to-network communication and is not suitable for remote data transmission due to the particularity of its application scenarios. Sensor device nodes become information islands, and truly comprehensive interconnection and interworking and collaborative perception cannot be implemented. In addition, there are various perception technologies in the IoT, and different communication protocols are used. This increases the difficulty of interconnection and interworking.
[3] At present, an edge computing technology is widely used in the IoT, especially in application scenarios with special service requirements such as low latency, high bandwidth, high reliability, massive connections, heterogeneous convergence, and local security and privacy protection. A smart IoT system of Internet of everything and ubiquitous IoT requires a network edge apparatus to collaborate with a service master station in a cloud, and implement functions such as edge computing and regional autonomy in addition to data acquisition and protocol conversion, to reduce analysis and decision-making pressure of the service master station in the cloud, so as to adapt to requirements of various IoT application scenarios.
[4] As a link between the wireless sensor network and a traditional communication network, an IoT gateway (also referred to as an intelligent gateway) completes protocol conversion between the wireless sensor network, the traditional communication network, and another different type of network, to implement local and wide area data interconnection. Because various communication technology protocols are incompatible, and the existing IoT gateway usually adopts point-to-point protocol conversion in operations and information exchange between heterogeneous networks, it is difficult to implement mutual conversion between various transmission protocols. In addition, the existing IoT gateway mainly acquires and forwards data, and transmits converged perceived source data (or simply preprocessed and cleaned data) to a backend management system. The backend management system analyzes and processes the data and makes a decision. The gateway has insufficient local data processing and local decision-making capabilities. In other words, the gateway performs few local decision-making and has a weak regional autonomy capability. This increases data analysis and decision-making pressure of the backend management system.
SUMMARY 151 The present disclosure provides an edge computing-based IoT proxy apparatus and data decision-making method to implement unified conversion of various transmission protocols, unified convergence and access of data from terminal devices, and local analysis and decision-making of the data.
[6] To achieve the foregoing objective, one aspect of the present disclosure provides an edge computing-based IoT proxy apparatus, applied to an IoT. The apparatus includes:
[71 a local communication module, configured to receive information acquisition source data sent by different terminal devices at a perception layer of the IoT;
[8] a protocol conversion module, configured to use different preset communication protocol specifications to resolve or convert the information acquisition source data sent by the different terminal devices;
191 a data analysis module, configured to analyze resolved or converted data, make a decision, and generate decision data; and
[10] a remote communication module, configured to convert the decision data by using a communication protocol corresponding to a remote communication mode of an IoT management platform in the IoT, and transmit converted decision data to the IoT management platform.
[11] Further, the using different preset communication protocol specifications to resolve or convert the information acquisition source data sent by the different terminal devices may specifically include:
[12] analyzing a transmission protocol used by each terminal device to send the information acquisition source data, selecting a communication protocol specification corresponding to the transmission protocol from the different preset communication protocol specifications, and using the communication protocol specification corresponding to the transmission protocol to resolve or convert the information acquisition source data.
[13] Further, the apparatus may include an application program module. Various communication protocol specification resolution programs are preset in the application program module.
[14] If the protocol conversion module selects no communication protocol specification corresponding to the transmission protocol from the different preset communication protocol specifications, a communication protocol specification resolution program corresponding to the transmission protocol in the application program module is called to resolve or convert the information acquisition source data.
[15] Further, the apparatus may include:
[16] a resource management module, configured to orderly manage the information acquisition source data sent by the different terminal devices and received by the local communication module, and schedule the protocol conversion module to resolve or convert the information acquisition source data in order.
[17] Further, the apparatus may include:
[18] a security encryption module, configured to encrypt the decision data to be transmitted to the IoT management platform.
[19] The edge computing-based IoT proxy apparatus in the present disclosure uses the local communication module to implement unified convergence and access of the source data acquired by the different terminal devices at the perception layer of the IoT, uses the protocol conversion module to convert the source data transmitted by using different transmission protocols to implement unified conversion of various transmission protocols, uses the data analysis module to analyze the converted data and make the decision, and finally uses the corresponding communication protocol to upload the decision data to the IoT management platform to implement unified convergence and access and standardized protocol-based upload of the data from the terminal devices at the edge of the IoT. The apparatus implements a smooth communication link between the perceived data and the management platform, intelligent data analysis, and the smart IoT with regional collaboration and autonomy. The IoT proxy apparatus implements unified convergence and access of local perceived data through protocol adaptation, and implements local analysis and decision-making of the accessed data from the edge of the IoT by using the data analysis module, without a need to request backend management systems such as the IoT management platform and a service master station. This reduces data analysis and decision-making pressure of the backend management systems such as the service master station.
[20] The present disclosure is applied to the IoT, and an application mode of cloud-edge collaboration (coordination of the cloud master station and the IoT proxy apparatus at the edge) greatly improves the operation analysis effectiveness and intelligence level of the terminal devices at the edge, and can reduce congestion of a remote data transmission channel and improve reliability of data delivery.
[21] Another aspect of the present disclosure provides an edge computing-based IoT proxy data decision-making method. The method includes:
[22] receiving information acquisition source data sent by different terminal devices at a perception layer of an IoT;

[27] analyzing a transmission protocol used by each terminal device to send the information acquisition source data, selecting a communication protocol specification corresponding to the transmission protocol from the different preset communication protocol specifications, and using the communication protocol specification corresponding to the transmission protocol to resolve or convert the information acquisition source data.
[28] Further, the method may include:
[29] if no communication protocol specification corresponding to the transmission protocol is selected from the different preset communication protocol specifications, calling a communication protocol specification resolution program corresponding to the transmission protocol to resolve or convert the information acquisition source data.
[30] Further, the method may include:
[31] orderly managing the received information acquisition source data sent by the different terminal devices, and resolving or converting the information acquisition source data in order.
[32] Further, the transmitting converted decision data to the IoT management platform may specifically include:
[33] encrypting the converted decision data and transmitting encrypted decision data to the IoT management platform.
[34] The edge computing-based IoT proxy data decision-making method in the present disclosure implements unified convergence and access of the source data acquired by the different terminal devices at the perception layer of the IoT, converts the source data transmitted by using different transmission protocols to data in a uniform format, analyzes the data, makes the decision, and uses the corresponding communication protocol to upload the decision data to the IoT management platform to implement unified convergence and access and standardized protocol-based upload of the data from the terminal devices at the edge of the IoT. The method implements a smooth communication link between the perceived data and the management platform, intelligent data analysis, and the smart IoT with regional collaboration and autonomy.
The method implements unified convergence and access of local perceived data through protocol adaptation, and implements local analysis and decision-making of the accessed data from the edge of the IoT, without a need to request backend management systems such as the IoT management platform and a service master station. This reduces data analysis and decision-making pressure of the backend management systems such as the service master station.
[35] Other features and advantages of the embodiments of the present disclosure are described in detail in the following specific embodiments.
[36] The accompanying drawings are provided for further understanding of the embodiments of the present disclosure, and constitute part of the specification.

[40] The embodiments of the present disclosure are described below with reference to the accompanying drawings. It should be understood that the embodiments described herein are merely intended to illustrate and interpret the present disclosure, rather than to limit the present disclosure.
[41] An edge computing-based IoT proxy apparatus provided in the embodiments of the present disclosure is applied to an IoT. FIG. 1 is a connection diagram of an edge computing-based IoT according to an embodiment of the present disclosure. As shown in FIG. 1, a network connection relationship of the IoT provided in this embodiment is as follows: Terminal devices at a perception layer are connected to an IoT proxy apparatus, the IoT proxy apparatus is connected to the IoT management platform, and the IoT management platform is connected to a service master station (namely, a cloud master station constructed in an IoT application industry and field). Located on a perception site of the IoT, the terminal devices at the perception layer are components with data acquisition functions such as perception, alternating current sampling, and metering, separate functional components, or sensors or terminals that implement data perception and acquisition functions on a site of the IoT. Located on the site of the IoT, the IoT proxy apparatus is connected to the terminal devices at the perception layer in a local communication mode, such as a controller area network (CAN), Recommended Standard 232 or 485, a carrier, Bluetooth, Zigbee, wireless fidelity (Wi-Fi), or micro-power wireless, and connected to the IoT management platform in a remote communication mode, such as an optical fiber, Ethernet, 4G, 5G, or Narrowband IoT (NB-IoT), to implement local communication mode and protocol specification adaptation and conversion functions for the terminal devices at the perception layer. The IoT proxy apparatus acquires all data from the terminal devices at the perception layer, performs protocol conversion, uses a uniform IoT specification to upload information to the IoT management platform, and performs local analysis and decision-making on the data. However, data transmission protocols between different terminal devices at the perception layer and the IoT proxy apparatus are different. When different terminal devices at the perception layer may simultaneously transmit source data acquired by themselves to the IoT proxy apparatus, the IoT proxy apparatus needs to be able to perform point-to-multipoint data acquisition, convert various transmission protocols, perform analysis and make decisions based on the acquired data, implement edge computing and regional autonomy, and collaborate with the IoT management platform to reduce analysis and decision-making pressure of the service master station.
[42] FIG. 2 is a structural block diagram of an edge computing-based IoT proxy apparatus according to an embodiment of the present disclosure. As shown in FIG. 2, an embodiment of the present disclosure provides an edge computing-based IoT proxy apparatus.

The local communication module is configured to receive information acquisition source data sent by different terminal devices at a perception layer of an IoT.
[43] The protocol conversion module is configured to use different preset communication protocol specifications to resolve or convert the information acquisition source data sent by the different terminal devices. Specifically, analyze a transmission protocol used by each terminal device to send the information acquisition source data, select a communication protocol specification corresponding to the transmission protocol from the different preset communication protocols, and use the communication protocol specification corresponding to the transmission protocol to resolve or convert the information acquisition source data.
[44] The data analysis module is configured to analyze resolved or converted data, make a decision, and generate decision data. The data analysis module includes a main control chip and a corresponding data analysis unit. The main control chip needs to have specific data processing and caching capabilities. For example, the main control chip has a dominant frequency not less than 1.2 GHz, a processor that has at least four cores, and tens of GB of synchronous dynamic random access memory (SDRAM) and flash memory, to implement data analysis, processing, and local decision-making.
[45] The remote communication module is configured to convert the decision data by using a communication protocol corresponding to a remote communication mode of an IoT management platform in the IoT, and transmit converted decision data to the IoT management platform, for example, use a uniform protocol, such as Message Queue Telemetry Transmission (MQTT), to upload the data to the IoT management platform.
[46] In this embodiment, the apparatus may further include a resource management module, an application program module, and a security encryption module. The resource management module is configured to orderly manage the information acquisition source data sent by the different terminal devices and received by the local communication module, and schedule the protocol conversion module to resolve or convert the information acquisition source data in order. Various communication protocol specification resolution programs are preset in the application program module. If the protocol conversion module selects no communication protocol specification corresponding to the transmission protocol from the different preset communication protocol specifications, a communication protocol specification resolution program corresponding to the transmission protocol in the application program module is called to resolve or convert the information acquisition source data. General communication protocols are preset or industry-specific communication protocols are dynamically expanded in the application program module to implement compatibility with all data transmission modes and communication protocols of the IoT as far as possible, and implement unified convergence and access of perceived data. The security encryption module is configured to encrypt the decision data to be transmitted to the IoT management platform, to implement security functions of hardware-level encryption and decryption.
[47] The IoT proxy apparatus in this embodiment is configured with a clock module and a power module. An industrial-grade clock circuit is used, which has its own crystal oscillator and supports high-speed inter-integrated circuit (12C) communication. The power module can implement wide-voltage input and regulated-voltage output, and supports overcurrent protection and normal power supply of each hardware functional module in the IoT proxy apparatus. In addition, a basic software platform adopted by the IoT proxy apparatus can provide stable and common software environments, such as an operating system, an edge computing framework, and an embedded virtualization technology application, to implement customized and tailored transplantation development based on a general and common software framework or platform.
[48] The edge computing-based IoT proxy apparatus provided in this embodiment of the present disclosure uses the local communication module to implement unified convergence and access of the source data acquired by the different terminal devices at the perception layer of the IoT, uses the protocol conversion module to convert the source data transmitted by using different transmission protocols to implement unified conversion of various transmission protocols, uses the data analysis module to analyze the converted data and make the decision, and finally uses the corresponding communication protocol to upload the decision data to the IoT management platform to implement unified convergence and access and standardized protocol-based upload of the data from the terminal devices at the edge of the IoT. The apparatus implements a smooth communication link between the perceived data and the management platform, intelligent data analysis, and the smart IoT with regional collaboration and autonomy. The IoT proxy apparatus implements unified convergence and access of local perceived data through protocol adaptation, and implements local analysis and decision-making of the accessed data from the edge of the IoT by using the data analysis module, without a need to request backend management systems such as the IoT management platform and a service master station.
