[0025] Embodiments of the present embodiment will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present embodiment are shown in the accompanying drawings, it should be understood that the present embodiment can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein, which are instead provided for a more thorough and complete understanding of the present embodiment. It should be understood that the drawings and embodiments of the present embodiment are only for exemplary purposes and are not intended to limit the scope of protection of the present embodiment.

[0026] In order to support multiple industrial protocols, the industrial edge gateway provided by the existing solution 1 collects, organizes, processes and monitors device data locally, and then sends this data to the IoT (Internet of Things). This solution runs on local hardware devices such as third-party industrial gateways and computers. This solution uses multiple industrial protocols to collect this data, including OPC UA (OLE for Process Control Unified Architecture, object linking and embedding process control), Modbus (a serial communication protocol), TCP / IP (Transmission Control Protocol / Internet Protocol) and Ethernet / IP (a communication protocol, communication protocol, which is based on the Ethernet standard and uses the Internet Protocol for communication), all of which are provided as pre-packaged connectors for operation. This method is deployed on the edge gateway, has high hardware resource requirements, and there are relatively few third-party industrial gateways that are adapted.

[0027] In the existing solution 2, the edge gateway supports the plug-in framework, supports different industrial protocols through protocol plug-ins, and can dynamically download plug-ins to the edge gateway. The plug-in supports Java (a computer language), C (a computer language), C# (a computer language) and other language SDKs (Software Development Kit), which are provided to third parties for integration on the edge side. The operating environment of this solution has relatively high requirements for resource hardware. Different third-party hardware needs to be adapted separately, and plug-ins need to be ported and developed separately for each hardware.

[0028] The edge industrial protocol gateway of the existing solution three uses lightweight industrial protocol gateway software, which allows more functional expansion by hot-swapping more driver modules. Each pluggable driver module works independently without interfering with each other and has its own specific capabilities. The different third-party hardware of this solution needs to be adapted and ported separately, and the plug-in needs to be ported and developed separately for the hardware.

[0029] In addition, considering that gateways are generally embedded systems, different models of gateways have different CPU architectures, hardware resource configurations, compilers, and runtime libraries of different versions. The development cycle for porting an industrial protocol to a piece of hardware is relatively long, and the development cycle will be even longer if multiple protocols are ported at the same time.

[0030] Based on the above background, the embodiments of the present invention provide a method and device for processing industrial control equipment protocols and an Internet of Things platform system. The industrial driver protocols of this solution are all implemented in the cloud and do not need to be adapted to different hardware, which simplifies the transplantation and development tasks. The protocol driver agent only implements the proxy forwarding function of the protocol frame, which has simple functions, low hardware cost, and universal functions, and the same hardware can be used to connect to multiple protocol devices.

[0031] The terms involved are explained below.

[0032] CNC (Computerized Numerical Control): Computer numerical control technology machine tools.

[0033] PLC (Programmable Logic Controller): A programmable logic controller is a digital computing and operating electronic system designed specifically for use in industrial environments.

[0034] DTU (Distribution Terminal Unit): A discrete terminal whose main responsibility is to transmit the data of remote devices back to the cloud wirelessly.

[0035] CloudDriver: Cloud driver center,implementing industrial protocols.

[0036] DriverAgent: Driver agent, deployed on independent hardware with a network interface. It can be connected to industrial control equipment through the network or serial port. The network can also be connected to the driver center in the cloud.

[0037] In an embodiment of the present invention, a method for processing a protocol for industrial control equipment is provided. The method can be applied to a protocol processing module arranged in a platform system. Both the platform system and the protocol processing module are deployed in the cloud. Figure 1 is a flowchart of the industrial control equipment protocol processing method according to an embodiment of the present application. Figure 1 The method steps involved are described.

[0038] Step S101: the protocol processing module obtains an uplink protocol frame, wherein the uplink protocol frame is generated by industrial control devices according to the industrial control protocols supported by the devices.

[0039] In this step, the uplink protocol frame is an industrial control protocol frame generated by the industrial control device. Since different industrial control devices support different industrial control protocols, the uplink protocol frame obtained by the protocol processing module is an industrial control protocol frame generated according to different industrial control protocols. In the embodiment of the present invention, the industrial control protocol frame generated by the industrial control device and processed by the protocol processing module is used as the uplink protocol frame. The industrial control device can generate an uplink protocol frame at a set time or time interval, or generate an industrial protocol frame according to a received acquisition instruction or control instruction.

[0040] It should be noted that industrial protocols refer to communication protocols used in the field of industrial automation, such as but not limited to: Modbus protocol, S7 protocol, OPC-UA protocol, Profibus protocol, BACnet protocol and CAN protocol. The industrial protocol frame refers to the data frame format transmitted in these protocols. The function of the protocol frame is to encapsulate the data in a certain format so that it can be transmitted and identified during the communication process. Usually, the protocol frame includes a data header, a data body, a check code, etc. Therefore, the industrial protocol and the industrial protocol frame are closely related. The protocol specifies the mode and content of data transmission, while the protocol frame is a specific data transmission format. The format and content of the protocol frame are usually specified by the communication protocol, and different communication protocols may use different protocol frame formats and contents. For example, the protocol frame of the Modbus protocol includes a start character, an address code, a function code, data, a check code, etc.; the protocol frame of the CAN protocol includes a frame header, data, a frame tail, etc.

[0041] It should also be noted that in the embodiments of the present invention, the industrial control equipment may include but is not limited to: CNC, PLC, sensor, distributed control system, human-machine interface, servo drive, motor controller, industrial computer, communication equipment, machine vision system and industrial robot, etc. The industrial control equipment can also be used to collect industrial control protocol frames of other industrial control equipment that are connected to the industrial control equipment.

[0042] In this step, the industrial protocol adopted by the industrial control equipment can be determined according to demand, or an industrial control equipment supported by a specified industrial protocol can be selected.

[0043] Step S102: the protocol processing module performs protocol processing according to the industrial control protocol corresponding to the uplink protocol frame, and parses and obtains industrial control data of the industrial control device during the protocol processing.

[0044] In this step, the protocol processing module can determine the industrial control protocol corresponding to the uplink protocol frame according to the protocol identification information carried in the uplink protocol frame, such as the identifier of the protocol class or the protocol name, and the protocol processing module performs protocol processing according to the industrial control protocol corresponding to the uplink protocol frame, thereby supporting multiple industrial protocols. Among them, the protocol processing mainly includes the processing steps of parsing data according to the protocol specification, receiving and responding to data according to the protocol flow, and parsing and obtaining the industrial control data of the industrial control equipment in the protocol processing.

[0045] In this step, the cloud platform implements various industrial protocols and transplants an industrial protocol on the cloud, which can be applied to all industrial control devices that support the protocol without adapting to different hardware, making the transplantation development task simple.

[0046] Step S103: the protocol processing module transmits the industrial control data to the industrial control data processing device in the platform system.

[0047] In this step, the protocol processing module transmits the industrial control data to the industrial control data processing device in the platform system, wherein the industrial control data processing device is communicatively connected with the protocol processing module.

[0048] It should be noted that in this step, the industrial control data may include point data. In order to facilitate the industrial control data processing device to perform data processing, before the protocol processing module transmits the industrial control data to the industrial control data processing device in the platform system, it can also convert the above point data into attribute data according to a preset corresponding mapping relationship. For example, if the industrial control device is an air conditioner, it is analyzed that the collected industrial control data includes first point data and second point data. According to the mapping relationship, it can be known that the first point data is the temperature data of the air conditioner, and the second point data is the humidity data of the air conditioner.

[0049] The embodiment of the present invention is applied to a protocol processing module set in a platform system, and the industrial control equipment protocol processing method includes: the protocol processing module obtains an uplink protocol frame, wherein the uplink protocol frame is generated by the industrial control equipment according to the industrial control protocol supported by each; the protocol processing module performs protocol processing according to the industrial control protocol corresponding to the uplink protocol frame, and parses and obtains the industrial control data of the industrial control equipment during the protocol processing; the protocol processing module transmits the industrial control data to the industrial control data processing equipment in the platform system. After the embodiment of the present invention obtains the uplink protocol frames of different industrial protocols, it performs protocol processing according to the industrial control protocol corresponding to the uplink protocol frame, can support multiple types of industrial protocols, parses and obtains the industrial control data of the industrial control equipment during the protocol processing, and transmits the industrial control data to the industrial control data processing equipment in the platform system, so as to realize the collection or control of the industrial control equipment.

[0050] In a possible implementation, the protocol processing module performs protocol processing according to the industrial control protocol corresponding to the uplink protocol frame, which can be executed according to the following steps: the protocol processing module parses the uplink protocol frame according to the industrial control protocol corresponding to the uplink protocol frame, generates a downlink protocol frame for responding to the uplink protocol frame, and sends the downlink protocol frame to a proxy server.

[0051] In this possible implementation, the protocol processing module parses the uplink protocol frame according to the industrial control protocol corresponding to the uplink protocol frame, obtains the industrial control data, and transmits the industrial control data to the industrial control data processing device in the platform system. After the user obtains the industrial control data through the industrial control data processing device, the user may issue an acquisition or control instruction based on the industrial control data through the cloud driver module. The protocol processing module can start the frame processing when receiving the acquisition or control instruction or according to the preset acquisition or control start condition, that is, during the protocol processing, a downlink protocol frame is generated to respond to the uplink protocol frame, and the downlink protocol frame is sent to the proxy server, so that the proxy server forwards the downlink protocol frame to the industrial control device.

[0052] It should be noted that, in the embodiment of the present invention, the industrial protocol frame generated in the protocol processing module and processed by the industrial control device is used as the downlink protocol frame.

[0053] In this step, the protocol processing module may parse the uplink protocol frame according to the industrial control protocol corresponding to the uplink protocol frame, or frame the uplink protocol frame to obtain a downlink protocol frame in response to the uplink protocol frame, thereby supporting multiple industrial protocols.

[0054] It should be noted that the industrial control protocol processing may include the following steps: receiving data packets: receiving data packets from the industrial control network. parsing data packets: parsing the header and payload of the data packets to determine the type and content of the data packets. verifying data packets: verifying the integrity and correctness of the data packets to ensure that the data packets are not spoofed or damaged. If the data packets are encrypted using an encryption algorithm, a decryption operation is required. performing a security check on the data packets to ensure that the data packets do not contain malicious code or attack behavior. performing a protocol check: performing a protocol check on the data packets to ensure that the data packets comply with the specifications of the industrial control protocol. processing data packets: performing corresponding processing operations according to the type and content of the data packets, such as controlling the device, collecting control data, etc. generating a response data packet: generating a corresponding response data packet according to the processing result to reply to the sender or notify other devices. encrypting the response data packet: encrypting the response data packet if necessary. sending a response data packet: sending the response data packet back to the industrial control network to complete the protocol processing process. It should be noted that the industrial control protocol processing may include the following steps: receiving data packets: receiving data packets from the industrial control network. parsing data packets: parsing the header and payload of the data packets to determine the type and content of the data packets. Verify the data packet: Verify the integrity and correctness of the data packet to ensure that the data packet has not been spoofed or damaged. If the data packet is encrypted using an encryption algorithm, a decryption operation is required. Perform a security check on the data packet to ensure that the data packet does not contain malicious code or attack behavior. Perform a protocol check: Perform a protocol check on the data packet to ensure that the data packet complies with the specifications of the industrial control protocol. Process the data packet: Perform corresponding processing operations based on the type and content of the data packet, such as controlling the device, collecting control data, etc. Generate a response data packet: Based on the processing results, generate a corresponding response data packet to reply to the sender or notify other devices. Encrypt the response data packet: If necessary, encrypt the response data packet. Send the response data packet: Send the response data packet back to the industrial control network to complete the protocol processing process.

[0055] In a possible implementation manner, the uplink protocol frame and the downlink protocol frame are forwarded by the proxy server between the protocol processing module and the industrial control device.

[0056] In this possible implementation, the proxy server is used to forward the uplink protocol frame generated by the industrial control device to the protocol processing module so that the protocol processing module can decode the frame to obtain the industrial control data. The proxy server is also used to forward the downlink protocol frame generated by the protocol processing module to the industrial control device to realize the collection or control of the industrial control device. The proxy server only realizes the forwarding function of the protocol frame, which is very simple, does not require high hardware resources, has a very low hardware cost, and the hardware can be applied to all protocols.

[0057] In a possible implementation, the proxy server is disposed at the industrial control device end, or is disposed in an industrial control gateway, and the industrial control gateway is disposed between the industrial control device and the platform system.

[0058] In this possible implementation, the proxy server is arranged on the industrial control device, or arranged in the industrial control gateway, and the industrial control gateway is arranged between the industrial control device and the platform system, so as to realize the communication between the industrial control device and the platform system.

[0059] In this step, the industrial protocol driver is implemented by the cloud, which can be applied to all industrial control devices that support the protocol. There is no need to burn or download the driver to the gateway or driver agent separately, and there is no need to adapt the driver for different embedded hardware. It can be adapted to all gateway hardware, and the development cycle is short.

[0060] In a possible implementation, the proxy server corresponds to the industrial control device one-to-one; before the protocol processing module obtains the uplink protocol frame, the method further includes: the protocol processing module obtains a connection request from the proxy server, and establishes a first connection channel with the proxy server based on the connection request, wherein the connection request carries an identifier of the industrial control device; the protocol processing module obtains connection parameters for connecting to the industrial control device based on the identifier of the industrial control device, and transmits the connection parameters to the proxy server through the first connection channel, so that the proxy server establishes a second connection channel with the industrial control device based on the connection parameters, and the first connection channel and the second connection channel are used to transmit the downlink protocol frame and the uplink protocol frame.

[0061] In this possible implementation, a proxy server is set up on each industrial control device. Before the protocol processing module obtains the uplink protocol frame, when the proxy server is powered on, it is connected to the protocol processing module through the network. The protocol processing module obtains a connection request from the proxy server, and establishes a first connection channel with the proxy server based on the connection request, wherein the connection request carries the identification of the industrial control device. In this step, a first connection channel is established between each proxy server and the protocol processing module. The protocol processing module obtains connection parameters for connecting to the industrial control device based on the identification of the industrial control device, and transmits the connection parameters to the proxy server through the first connection channel, so that the proxy server establishes a second connection channel with some or all of the industrial control devices based on the connection parameters. It should be noted that in this step, the industrial control device that needs to establish a second connection channel with the proxy server may be the industrial control device that is intended to be collected or controlled.

[0062] In this step, protocol frame transmission between the industrial control device, the proxy server, and the protocol processing module is implemented through the first connection channel and the second connection channel.

[0063] In a possible implementation, the proxy server is assigned a key, and the uplink protocol frame and the downlink protocol frame are both forwarded by the proxy server through the first connection channel and the second connection channel encrypted based on the key; the protocol processing module obtains the plaintext data of the uplink protocol frame and the downlink protocol frame based on the key.

[0064] In this possible implementation, each proxy server is assigned a unique key and identifier, the identifier is used to identify the proxy server, and the key is used to encrypt the first connection channel and the second connection channel to ensure the security of the transmitted data, that is, the proxy server is assigned a key, and the uplink protocol frame and the downlink protocol frame are forwarded by the proxy server through the first connection channel and the second connection channel encrypted based on the key. The protocol processing module obtains the plaintext data of the uplink protocol frame and the downlink protocol frame based on the key.

[0065] In this step, a symmetric encryption algorithm or an asymmetric encryption algorithm may be used. The specific encryption algorithm may be selected according to actual needs, and the embodiment of the present invention does not specifically limit this.

[0066] Taking into account that the transmission of industrial protocol frames over the Internet will introduce additional overhead, therefore, in a possible implementation, after the protocol processing module obtains the uplink protocol frame, the method further includes: the protocol processing module decompresses and processes the uplink protocol frame, wherein the uplink protocol frame is compressed and processed by the proxy server; after the protocol processing module generates a downlink protocol frame for responding to the uplink protocol frame, the method further includes: the protocol processing module compresses and processes the downlink protocol frame.

[0067] In this possible implementation, after the protocol processing module obtains the uplink protocol frame, the method further includes: the protocol processing module decompresses the uplink protocol frame, wherein the uplink protocol frame is compressed by the proxy server. That is, the proxy server sends the compressed uplink protocol frame to the protocol processing module, and after receiving the uplink protocol frame, the protocol processing module first decompresses the uplink protocol frame.

[0068] After the protocol processing module generates a downlink protocol frame for responding to the uplink protocol frame, the method further includes: the protocol processing module compresses the downlink protocol frame. That is, the protocol processing module compresses the downlink protocol frame before sending it to the proxy server.

[0069] In this step, before transmitting the uplink protocol frame or the downlink protocol frame, the industrial protocol frame data is compressed, so that the amount of transmitted data can be greatly reduced.

[0070] It should be noted that when compressing industrial coroutines, it is necessary to consider the processing speed of the compression algorithm and the size of the compressed data to ensure that the compressed data can be effectively transmitted and decompressed during network transmission. The specific compression method used can be selected according to actual needs, and the embodiment of the present invention does not make specific limitations on this.

[0071] In a possible implementation manner, the protocol processing module acquiring the uplink protocol frame includes: the protocol processing module acquiring an uplink setting protocol frame, wherein the uplink setting protocol frame is encapsulated with the uplink protocol frame based on a setting protocol, and the setting protocol is a private protocol between the protocol processing module and the proxy server; based on the setting protocol, parsing the uplink setting protocol frame to acquire the uplink protocol frame;

[0072] The protocol processing module sends the downlink protocol frame to the industrial control device, including: the protocol processing module encapsulates the downlink protocol frame into a downlink setting protocol frame based on the setting protocol, sends the downlink setting protocol frame to the proxy server, so that the proxy server parses the downlink setting protocol frame based on the setting protocol, obtains the downlink protocol frame, and sends the downlink protocol frame to the industrial control device.

[0073] In this possible implementation, the setting protocol is a private protocol between the protocol processing module and the proxy server. The setting protocol can be determined according to actual needs, and the embodiment of the present invention does not specifically limit this. By setting the protocol, the format of the industrial protocol frames transmitted in different industrial protocols can be unified for data processing. For example, the setting protocol can be to encapsulate the protocol frame in the format of frame header + frame data. Then, according to the setting protocol, the uplink protocol frame or the downlink protocol frame can be used as the frame data, and then according to the type of industrial protocol and other information, the frame header is designed for the frame data to obtain the uplink setting protocol frame or the downlink setting protocol frame.

[0074] It should be noted that the uplink setting protocol frame or the downlink setting protocol frame may also be compressed and / or encrypted before transmission. The specific configuration may be based on actual needs, and the embodiment of the present invention does not specifically limit this.

[0075] See also Figure 2 The schematic diagram of the implementation structure of the industrial control equipment protocol processing method in the industrial Internet of Things platform is shown below. The implementation of this method in the industrial Internet of Things platform of IoT products is described with a specific embodiment.

[0076] In an embodiment of the present invention, the industrial control device may include a 4G DTU, and a driver agent, namely the above-mentioned proxy server, is deployed on the edge 4G DTU or the gateway; the CloudDriver service ( Figure 2 The driver protocol parsing module is deployed in the industrial IoT platform. The DTU is connected to the industrial control equipment to be collected, remotely collects the power consumption status of photovoltaic equipment, remotely controls the equipment on the factory production line, and monitors equipment abnormalities.

[0077] The embodiment of the present invention also provides an industrial control device protocol processing method, which is applied to a proxy server, and the proxy server is set on the industrial control device, see Figure 6 The process of industrial control equipment protocol processing shown Figure 2 , the method comprising:

[0078] Step S601: collecting industrial control protocol frames generated by industrial control equipment according to supported industrial protocols.

[0079] In this step, the proxy server collects the industrial control protocol frames generated by the industrial control device according to the industrial protocol supported by the industrial control device. The industrial control device can generate uplink protocol frames at set times or time intervals, or generate industrial protocol frames according to received collection instructions or control instructions.

[0080] It should be noted that industrial protocols refer to communication protocols used in the field of industrial automation, such as but not limited to: Modbus protocol, S7 protocol, OPC-UA protocol, Profibus protocol, BACnet protocol and CAN protocol. The industrial protocol frame refers to the data frame format transmitted in these protocols. The function of the protocol frame is to encapsulate the data in a certain format so that it can be transmitted and identified during the communication process. Usually, the protocol frame includes a data header, a data body, a check code, etc. Therefore, the industrial protocol and the industrial protocol frame are closely related. The protocol specifies the mode and content of data transmission, while the protocol frame is a specific data transmission format. The format and content of the protocol frame are usually specified by the communication protocol, and different communication protocols may use different protocol frame formats and contents. For example, the protocol frame of the Modbus protocol includes a start character, an address code, a function code, data, a check code, etc.; the protocol frame of the CAN protocol includes a frame header, data, a frame tail, etc.

[0081] It should also be noted that in the embodiments of the present invention, industrial control equipment may include but is not limited to: CNC, PLC, sensors, distributed control systems, human-machine interfaces, servo drives, motor controllers, industrial computers, communication equipment, machine vision systems, and industrial robots.

[0082] In this step, the industrial protocol adopted by the industrial control equipment can be determined according to demand, or an industrial control equipment supported by a specified industrial protocol can be selected.

[0083] Step S602: forward the industrial control protocol frame as an uplink protocol frame to a protocol processing module, so that the protocol processing module performs protocol processing according to the industrial control protocol corresponding to the uplink protocol frame, and parses and obtains industrial control data of the industrial control device during the protocol processing.

[0084] In this step, in the embodiment of the present invention, the industrial control protocol frame generated by the industrial control device and processed by the protocol processing module is used as the uplink protocol frame. The uplink protocol frame is an industrial control protocol frame generated by the industrial control device. Since different industrial control devices support different industrial control protocols, the uplink protocol frame obtained by the protocol processing module is an industrial control protocol frame generated according to different industrial control protocols.

The protocol processing mainly includes parsing data according to the protocol specification, and receiving and responding to data according to the protocol flow, and the industrial control data of the industrial control equipment is obtained by parsing in the protocol processing.

[0086] In this step, the cloud platform implements various industrial protocols. An industrial protocol is transplanted in the cloud, which can be applied to all industrial control devices that support the protocol without adapting to different hardware, making the transplantation development task simple. The proxy server only implements the forwarding function of the protocol frame. The function is very simple, the hardware resource requirements are not high, the hardware cost is very low, and the hardware can be applied to all protocols.

[0087] The embodiment of the present invention provides an industrial control equipment protocol processing method, which can support various types of industrial protocols, has low hardware requirements for a proxy server, and greatly reduces hardware costs.

[0089] Step S701: the proxy server collects industrial control protocol frames generated by industrial control equipment according to supported industrial protocols; and forwards the industrial control protocol frames as uplink protocol frames to a protocol processing module.

[0094] In a possible implementation manner, the uplink protocol frame and the downlink protocol frame are forwarded by the proxy server between the protocol processing module and the industrial control device.

[0095] In a possible implementation, the proxy server is disposed at the industrial control device end, or is disposed in an industrial control gateway, and the industrial control gateway is disposed between the industrial control device and the platform system.

[0096] In a possible implementation, the proxy server corresponds to the industrial control device one-to-one; before the protocol processing module obtains the uplink protocol frame, the method further includes: the protocol processing module obtains a connection request from the proxy server, and establishes a first connection channel with the proxy server based on the connection request, wherein the connection request carries an identifier of the industrial control device; the protocol processing module obtains connection parameters for connecting to the industrial control device based on the identifier of the industrial control device, and transmits the connection parameters to the proxy server through the first connection channel, so that the proxy server establishes a second connection channel with the industrial control device based on the connection parameters, and the first connection channel and the second connection channel are used to transmit the downlink protocol frame and the uplink protocol frame.

[0097] In a possible implementation, the proxy server is assigned a key, and the uplink protocol frame and the downlink protocol frame are both forwarded by the proxy server through the first connection channel and the second connection channel encrypted based on the key; the protocol processing module obtains the plaintext data of the uplink protocol frame and the downlink protocol frame based on the key.

[0098] In a possible implementation, after the protocol processing module obtains the uplink protocol frame, the method further includes: the protocol processing module decompresses and processes the uplink protocol frame, wherein the uplink protocol frame is compressed and processed by the proxy server; after the protocol processing module generates a downlink protocol frame for responding to the uplink protocol frame, the method further includes: the protocol processing module compresses and processes the downlink protocol frame.

[0100] An embodiment of the present invention also provides a proxy server, including: a collection unit, used to collect industrial control protocol frames generated by industrial control equipment based on supported industrial protocols; a forwarding unit, used to forward the industrial control protocol frames as uplink protocol frames to a protocol processing module, so that the protocol processing module can perform protocol processing based on the industrial control protocol corresponding to the uplink protocol frame, and parse and obtain the industrial control data of the industrial control equipment during the protocol processing.

[0101] In a possible implementation manner, the method further includes: a receiving unit configured to receive a downlink protocol frame sent by the protocol processing module; and the forwarding unit configured to forward the downlink protocol frame to the industrial control device.

[0102] An embodiment of the present invention also provides an Internet of Things platform system, characterized in that it includes an Internet of Things platform, industrial control equipment, the above-mentioned industrial control equipment protocol processing device and the above-mentioned proxy server; wherein the Internet of Things platform includes a driving module and an industrial control data processing device; the industrial control equipment protocol processing device is communicatively connected to the Internet of Things platform; and each of the industrial control equipment is provided with the proxy server.

[0103] See also Figure 3 The schematic diagram of the implementation framework of the industrial control equipment protocol processing method is shown, and the specific implementation method of the Internet of Things platform system of the embodiment of the present invention is described below. The Internet of Things platform includes a driver module and an industrial control data processing device, wherein the driver module is used to implement the driver model, and the driver model can be used for driver management. The cloud driver center is the protocol processing module, and the protocol processing module adopts the industrial control equipment protocol processing device, and the driver agent is the proxy server. The protocol processing module and the Internet of Things platform are deployed in the cloud, and the industrial control equipment protocol processing device is communicatively connected with the Internet of Things platform; each of the industrial control equipment is provided with the proxy server.

[0104] The protocol driver agent is deployed on the edge side, directly connected to the industrial control equipment, and can connect to the CloudDriver in the cloud through the network. CloudDriver is deployed in the cloud and is responsible for parsing the industrial protocol. The IoT platform is deployed in the cloud and communicates directly with CloudDriver to read the data collected by CloudDriver or remotely control the factory equipment through CloudDriver.

[0105] Based on the above implementation framework, the industrial protocol is implemented by CloudDriver deployed on the cloud. When collecting and controlling industrial control equipment at the edge, there is no need to modify any program of the protocol agent deployed at the edge. You only need to configure the driver protocol on the cloud, which shortens the implementation cycle. Figure 5 The implementation process of the industrial control equipment protocol processing method shown in the figure is as follows:

[0106] 1. When the protocol driver agent is powered on, it connects to the cloud driver center through the network. Clouddriver verifies the legitimacy of the device based on the device ID and establishes a connection channel between the protocol driver agent and Clouddriver.

[0107] 2. CloudDriver sends the connection parameters required by the industrial control device to the driver agent based on the user configuration.

[0108] 3. The protocol driver agent connects to the local industrial control device according to the connection parameters issued.

The cloud platform implements the industrial bus protocol driver, which is responsible for parsing various industrial bus protocols, assembling protocol frames, and disassembling protocol frames. The protocol driver agent has simple implementation logic, few functions, low requirements on CPU performance and hardware resources, and very low hardware costs. The cloud platform implements various industrial protocols, and once a protocol is transplanted, it can be oriented to all driver agent hardware.
