[0034] Embodiment 1

[0035] Figure 1 It is a structural diagram of an industrial edge computing gateway system based on the Internet of Things provided by Embodiment 1 of the present invention, comprising: a server 110, a router 120, at least two edge gateways 130 and a management terminal 140, each of the edge gateways being communicatively connected;

[0036] Each of the edge gateways 130 is used to obtain working data of at least one connected device and / or other edge gateways 130, wherein the working data represents data generated or obtained by the connected device during operation; and perform data fusion processing and analysis on the working data;

[0037] The router 120 is used to realize the communication between the server 110 and the edge gateway 130 via WiFi to upload the working data and / or the processing and analysis results of the working data;

[0038] The management terminal 140 is used to configure all built-in parameters of the edge gateway and its subordinate industrial devices or sensor devices, including parameter configuration required for the network connection of the edge gateway.

[0039] Among them, the northbound communication between the edge gateway and the server is realized based on the WiFi network, replacing the traditional industrial gateway equipment to use 4G or 5G network communication. Advantages: easy deployment, no traffic fees, meeting the demand for industrial data not to be on the public network to avoid factory data exposure on the public network and information security issues. The gateways are interconnected and can transmit information to each other. They are not independent devices. The processing and analysis of sensor data and industrial equipment data are realized inside the edge gateway, and the emergency processing mechanism is realized inside the edge gateway to reduce server load and shorten emergency processing and response time.

[0040] In addition, the WiFi network can be replaced by RF433, Lora, or a custom 2.4G wireless communication network.

[0041] In an embodiment of the present invention, an edge gateway is configured with a serial port converter compatible with RS232 and RS485; the connected devices include: industrial equipment; accordingly, the edge gateway is used to detect whether the serial port signal type of the industrial equipment is RS232 or RS485 and dynamically switch the working mode of the serial port converter, wherein RS232 and RS485 correspond to different working modes, and each working mode includes different electrical characteristics.

[0042] RS232 and RS485 are two different serial communication standards, which have significant differences in signal level, communication mode and electrical characteristics. Therefore, to achieve automatic adaptation on the same serial port, you need to use a specially designed circuit or chip, usually called a serial port converter or serial port adapter.

[0043] This type of serial port converter usually has the following features:

[0044] Automatic detection function: can detect the signal type on the serial port and determine whether it is RS232 or RS485.

[0045] Automatic switching mode: Automatically adjust the serial port working mode according to the detected signal type to adapt to different device connections.

[0046] Electrical characteristics conversion: RS232 and RS485 have significant differences in electrical characteristics, including electrical levels, line drive capabilities, etc. The converter needs to be able to correctly convert these electrical characteristics to ensure correct communication between devices.

[0047] Communication rate adaptation: Serial port converters usually support a wide range of communication rates to meet the communication requirements of different devices.

[0048] Protection circuit: Protects serial ports and devices to prevent damage or communication errors caused by mismatched electrical characteristics.

[0049] The shared serial port application scenarios of RS232 and RS485 may appear in some industrial control equipment, for example. By using a specially designed serial port converter, RS232 and RS485 devices can be connected and communicated without manually adjusting the settings. This converter will automatically identify and adapt to the type of device connected, allowing users to configure and operate the device more conveniently.

[0050] In summary, the key to achieving RS232 and RS485 sharing the same serial port and automatically adapting is to use a serial port converter or adapter with automatic identification, conversion and adaptation functions. This can effectively solve the electrical and protocol differences between different communication standards and ensure normal communication and data exchange between devices.

[0051] In an embodiment of the present invention, each edge gateway is connected via a Bluetooth mesh network communication; accordingly, the management terminal is used to send WiFi configuration information to an edge gateway via Bluetooth communication, so that other edge gateways transmit the WiFi configuration information via the Bluetooth mesh network to connect to the router and connect to the server through the router.

[0052] Most smart devices provide two common network configuration methods: AP mode and SmartConfig mode (also known as AirKiss, One-click network configuration, etc.).

[0053] AP mode (Access Point mode): The device itself acts as a WiFi hotspot. You connect to this hotspot through a mobile phone or computer, and then enter the target WiFi information through the network configuration APP or web interface.

[0054] SmartConfig mode: The device receives WiFi information through sound waves or other special wireless signals.

[0055] If you choose AP mode, turn on the device, wait for the device to start the WiFi hotspot, and then connect to this hotspot through your mobile phone or computer.

[0056] If SmartConfig mode is selected, a dedicated network configuration APP is usually required or specific operation steps are performed to trigger the device to enter the network configuration mode, and then the WiFi information is entered in the APP, or the WiFi information is transmitted to the device through sound waves or other methods.

[0057] The solution used in the embodiment of the present invention is to support the above two network configuration modes, AP mode and SmartConfig mode, at the same time, and is based on Bluetooth communication between the network configuration APP and the device to trigger the seamless switching of the two modes and transmit the network configuration information.

[0058] The administrator configures the edge gateway and all its subordinate devices through the management terminal device, where the management terminal device includes but is not limited to mobile terminal devices such as mobile phones. The configuration software of the management terminal device can be mobile phone APP, WeChat applet, PC software, Web page configuration, etc. The management terminal device can be a mobile terminal device such as a mobile phone, tablet computer, laptop computer, etc. Based on the local area network communication of the Bluetooth mesh network, the edge gateways actively discover and automatically complete the Bluetooth mesh network networking, and the edge gateways are interconnected and can transmit information to each other. WiFi and Bluetooth dual-mode coexist, WiFi does not need to switch working modes, and Bluetooth can be used to achieve fast network configuration of WiFi. The handheld terminal configuration device only needs to establish Bluetooth communication with one of the gateways and send the configuration information to one gateway. Other gateways transmit configurations to each other through the Bluetooth mesh network to achieve fast WiFi configuration and connect to the specified server.

[0059] In addition, the Bluetooth mesh network can be replaced by RF433, Zigbee, or a customized 2.4G wireless communication network.

[0060] In an embodiment of the present invention, the edge gateway uses at least one of a symmetric encryption algorithm and an asymmetric encryption algorithm to encrypt data, and uses at least one of a digital certificate, a user name and password, fingerprint recognition, and facial recognition to authenticate access.

[0061] In addition, a security module can be built into the edge gateway to encrypt data transmitted by the gateway and authenticate access to the gateway to ensure data security and gateway access control. Its working principle is: use at least one of the symmetric encryption algorithm and asymmetric encryption algorithm to encrypt data. For the encryption process, select the appropriate encryption algorithm and key length according to the importance of the data and the transmission scenario. During the data transmission process, the data is encrypted and packaged to ensure the confidentiality and integrity of the data. Use at least one of digital certificates, user names and passwords, fingerprint recognition, facial recognition, etc. to authenticate access to the gateway. Set different authentication methods and verification processes according to different access levels and user types.

[0062] In an embodiment of the present invention, the connected device also includes: a sensor; each sensor is used to sense at least one physical quantity in the working environment of the corresponding industrial equipment; accordingly, an edge gateway is used to obtain the physical quantities obtained by the sensor and the operating status data and production parameter data of the industrial equipment; the physical quantities and production parameter data are used as working data, and data fusion processing and analysis are performed on the working data.

[0063] The access of industrial field environment detection sensors based on Bluetooth mesh network enables a set of gateway solutions to access industrial equipment and sensor equipment at the same time. Its working principle is: through the communication protocol and related interface standards of Bluetooth mesh network, it identifies and receives the data sent by the sensor, and incorporates the sensor into the management scope of the gateway.

[0064] In the embodiment of the present invention, the edge gateway is used to fuse the working data using a mathematical model and perform processing and analysis based on the fusion result;

[0065] In an embodiment of the present invention, the edge gateway is used to set weights for the working data of the sensor and the working data of the industrial equipment, and then perform weighted average calculation to obtain a fusion result, and perform processing and analysis based on the fusion result.

[0066] Among them, the data fusion calculation of industrial field environment detection sensor data and industrial equipment based on Bluetooth mesh network is realized inside the edge gateway, and an emergency processing mechanism is established. Its working principle is: collect and pre-process the data from sensors and industrial equipment, and then fuse the data according to the preset fusion algorithm, analyze and process the fused data inside the edge gateway, and activate the emergency processing mechanism according to the analysis results.

[0067] For industrial field environment detection sensors, they sense various physical quantities in the environment, such as temperature, humidity, pressure, gas concentration, etc., through their built-in sensor elements, and convert these physical quantities into electrical signals. The sensor sends the data represented by the electrical signal to the edge gateway according to its own communication protocol, such as the Bluetooth mesh network protocol. Different types of sensors may have different data formats and sampling frequencies. The edge gateway needs to identify and receive these data to ensure the integrity and accuracy of the data.

[0068] Industrial equipment connects to the communication interface module of the gateway through its own communication interface, such as RS232, RS485, etc. Industrial equipment sends the equipment's operating status data, production parameter data, etc. to the edge gateway according to its internal operating logic and data generation mechanism.

[0069] In addition, preprocessing the collected sensor data and industrial equipment data is an important preliminary step for fusion calculation. Preprocessing may include data cleaning to remove noise, outliers, and erroneous data in the data. For example, for temperature sensor data, if there are values ​​that are obviously beyond the normal range, it may be caused by sensor failure or interference, which needs to be identified and processed. It may also include data standardization to unify data from different sources to a standard scale. For example, temperature data of different ranges can be unified into a specific temperature range to facilitate subsequent fusion calculation and comparative analysis.

[0070] In an embodiment of the present invention, the edge gateway is used to analyze and process the fusion result internally; when the fusion result shows that the industrial equipment has an abnormal situation, the emergency processing mechanism is started according to pre-set thresholds and judgment rules, and one or more of the operating parameters of the industrial equipment and alarm information is sent to the server.

[0071] For the data fusion algorithm at the edge gateway, it can be implemented through rule-based fusion algorithm, model-based fusion algorithm and weighted average-based fusion algorithm. The rule-based fusion algorithm fuses data according to pre-set rules. For example, if the sensor detects that the ambient temperature is too high, and the relevant parameters of the cooling system of the industrial equipment show that the cooling efficiency is reduced, according to the pre-set rules, it can be judged that the industrial equipment may have an overheating risk. The rules can be set by domain experts based on the actual experience and knowledge of industrial production, or determined by analyzing and mining a large amount of historical data. The model-based fusion algorithm uses a mathematical model to fuse data. For example, a neural network model, a Bayesian network model, etc. can be used. Taking the neural network model as an example, the sensor data and the industrial equipment data are used as the input layer of the neuron input, and the hidden layer of the neural network is used to extract features and process data, and finally the fusion result is obtained at the output layer. In practical applications, the selection of the model needs to be based on the specific application scenario and data characteristics. Different models have different advantages and scopes of application. The weighted average-based fusion algorithm gives certain weights to the sensor data and the industrial equipment data respectively, and then performs weighted average calculation to obtain the fusion result. For example, for a fusion calculation that considers both ambient temperature and industrial equipment temperature, if the weight of ambient temperature on the overall temperature is 0.4 and the weight of industrial equipment temperature is 0.6, then the fused temperature = 0.4 × ambient temperature + 0.6 × industrial equipment temperature. The weight can be determined based on the importance and reliability of the data and the degree of influence on the fusion result.

[0072] The fusion results are analyzed and processed inside the edge gateway. For example, if the fusion results show that the industrial equipment has abnormal conditions, such as excessive temperature or abnormal pressure, the gateway can make corresponding decisions based on the pre-set thresholds and judgment rules, such as starting the emergency response mechanism, adjusting the operating parameters of the industrial equipment, or sending alarm information to the server. The analysis results can also be used to optimize the industrial production process, such as adjusting the production plan or equipment maintenance plan based on the fusion results of the ambient temperature and the operating status of the industrial equipment.

[0073] The fusion results can be stored inside the edge gateway for subsequent query and analysis. At the same time, as needed, the fusion results can be transmitted to the server in a certain communication protocol and format for further analysis and processing in a higher-level system. During data transmission, the security and integrity of the data need to be ensured, and encryption and other technical means can be used to protect it.

[0074] Figure 2 : is a topology diagram of an industrial edge computing gateway system used in the first embodiment of the present invention, such as Figure 2 As shown in the figure, the northbound communication of the gateway is the WiFi network, the interconnection between gateways is the Bluetooth mesh network, and the southbound communication of the gateway is the Bluetooth wireless connection communication that supports sensor devices in addition to the traditional wired connection communication such as RJ45, CAN, RS232, RS485. The administrator configures the edge gateway and all its subordinate devices through the management terminal device, where the management terminal device includes but is not limited to mobile terminal devices such as mobile phones. The configuration software of the management terminal device can be a mobile phone APP, WeChat applet, PC software, Web page configuration, etc. RS232 and RS485 share a serial port, which can realize the connection and automatic adaptation of RS232 and RS485 devices without manual adjustment of settings.

[0075] In summary, the solution of the embodiment of the present invention has at least the following advantages and improvements:

[0076] 1. Realize northbound communication between edge gateway and server based on WiFi network, instead of using 4G or 5G network communication of traditional industrial gateway equipment.

[0077] 2. Based on the local area network communication of Bluetooth mesh network, gateways actively discover and automatically complete Bluetooth mesh network networking.

[0078] 3. WiFi and Bluetooth dual-mode coexist, WiFi does not need to switch working modes, and the handheld terminal configuration device can quickly configure the WiFi of the edge gateway through Bluetooth communication.

[0079] 4. An access solution for industrial field environment detection sensors based on Bluetooth mesh network. A gateway solution can connect industrial equipment and sensors at the same time.

[0080] The industrial field environment detection sensor data based on the Bluetooth mesh network and the data of industrial equipment are integrated and calculated inside the edge gateway, and an emergency processing mechanism is implemented on the edge side.
