[0002] In the context of the open architecture of the Industrial Internet, open and interconnected industrial control networks not only require real-time control on-site, but also network interconnection and long-distance transmission.

[0045] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0046] A communication method, industrial network architecture, and communication device based on a converged industrial network according to an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0047] As mentioned above, in the traditional industrial Ethernet network environment, industrial Ethernet connects various industrial devices, enabling data information exchange between devices, and realizing the interconnection function of industrial equipment through wired means. However, the communication protocols between different devices use the industrial Ethernet dominated by major manufacturers, resulting in different communication protocols for devices used in industrial sites, and different data scheduling, which increases the application complexity and use cost of industrial sites. At the same time, because the communication time bases of equipment manufacturers are also different, there is no unified time standard for communication between devices, making real-time communication difficult.

[0048] Figure 1 1 is a flow chart of a communication method based on a converged industrial network provided in an embodiment of the present application. Figure 1 As shown, the communication method based on the integrated industrial network includes the following steps:

[0049] In step S101 , a first process management system acquires an industrial control message.

[0050] The first process management system is located in the first industrial local area network in the integrated industrial network, and the destination address of the industrial control message is the target controller in the target industrial local area network.

[0051] In step S102, in response to determining that the target industrial local area network is the first industrial local area network, an industrial control message is sent to a time sensitive network, and the time sensitive network sends the control message to the target controller after completing the scheduling.

[0052] In step S103, in response to determining that the target industrial local area network is the second industrial local area network, the industrial control message is sent to the second process management system in the second industrial local area network through the mobile communication network.

[0053] In step S104, the second process management system sends the industrial control message to the time sensitive network, and the time sensitive network sends the control message to the target controller after completing the scheduling.

[0054] Among them, the second industrial LAN is an industrial LAN in the integrated industrial network that is different from the first industrial LAN.

[0055] In some embodiments of the present application, the communication method based on the integrated industrial network can be executed by an industrial network system, and a specific component in the industrial network system transmits the industrial control message to the target controller. Among them, the controller can be a unit module in an industrial control system for executing various electrical and electronic technical tasks formulated by IEC (International Electrotechnical Commission), or a unit module in an industrial control system for executing IO (Input Output) data exchange tasks, or a unit module in an industrial control system for executing IO data voting tasks, or a unit module for executing other control tasks, which is not limited here.

[0056] In some implementations, the industrial control message may be obtained by a first process management system in the converged industrial network, the first process management system being located in a first industrial local area network in the converged industrial network, and the destination address of the industrial control message being a target controller in a target industrial local area network. The process management system is a system for managing how a controller operates.

[0057] Furthermore, if the target industrial LAN is determined to be the first industrial LAN, the industrial control message can be sent to the time-sensitive network. The time-sensitive network receives the industrial control message, schedules the transmission of the industrial control message based on various parameters in the industrial LAN, and sends the control message to the target controller after the scheduling is completed.

[0058] Furthermore, if the target industrial LAN is determined to be the second industrial LAN, the industrial control message can be sent to the second process management system in the second industrial LAN through the mobile communication network. The second process management system further sends the industrial control message to the time-sensitive network, and the time-sensitive network sends the control message to the target controller after completing the scheduling. The second industrial LAN is an industrial LAN different from the first industrial LAN in the integrated industrial network.

[0059] It is understandable that the time-sensitive networks in different industrial LANs may also be different, that is, the process management system and controller in the same industrial LAN may communicate via the time-sensitive network in the industrial LAN.

[0060] According to the technical solution provided in the embodiment of the present application, an industrial LAN including a time-sensitive network, a process management system and a controller is deployed in the industrial LAN, and a wireless communication network is deployed between the industrial LANs. The industrial control messages obtained by the process management system in the first industrial LAN are directly sent to the controller in the industrial LAN through the time-sensitive network, and are sent to the controllers in other industrial LANs through the wireless communication network, thereby realizing cross-network and cross-regional collaborative real-time control, thereby improving the real-time and heterogeneous nature of industrial information communication.

[0061] Figure 2 is a flow chart of another communication method based on a converged industrial network provided in an embodiment of the present application. Figure 2 Steps S201 to S204 in the embodiment shown are Figure 1 Steps S101 to S104 in the illustrated embodiment are substantially the same and will not be described in detail herein. Figure 2 As shown, the method also includes the following steps:

[0062] In step S205, after receiving the control message, the target controller controls the industrial device through the industrial real-time Ethernet based on the instructions in the control message.

[0063] Among them, the industrial equipment includes at least one of the following: a controlled industrial device, a controlled industrial production line, a transmitter, a sensor, an actuator, a wireless instrument, a wireless access point, and a wireless terminal.

[0064] In some embodiments of the present application, after receiving the control message, the target controller controls the industrial equipment through the industrial real-time Ethernet based on the instructions in the control message, so that the industrial equipment acts according to the control instructions carried in the control message. Among them, the industrial equipment may include industrial intelligent equipment, such as controlled industrial devices, controlled industrial production lines, etc.; may also include digital or analog or remote IO equipment, such as transmitters, sensors, actuators, etc.; may also include industrial gateway equipment, such as wireless instruments, wireless AP (Access Point), etc.; may also include wireless IP equipment, such as wireless terminals, etc.

[0065] Figure 3 is a flow chart of another communication method based on a converged industrial network provided in an embodiment of the present application. Figure 3 Steps S301 to S304 in the embodiment shown are Figure 1 Steps S101 to S104 in the illustrated embodiment are substantially the same and will not be described in detail herein. Figure 3 As shown, the method also includes the following steps:

[0066] In step S305, the target controller receives the reporting information sent by the industrial device through the industrial real-time Ethernet, and sends the reporting information to the time-sensitive network.

[0067] In step S306, the time sensitive network sends a control message to the target process management system after completing the scheduling.

[0068] The target process management system is a process management system in a target industrial local area network.

[0069] In some embodiments of the present application, the target controller may also receive reporting information sent by industrial equipment via industrial real-time Ethernet, and then send the reporting information to the time-sensitive network. Further, the time-sensitive network may send a control message to the target process management system after completing the scheduling.

[0070] For example, the target controller can receive the report information sent by the sensor including the industrial data collected by it, or receive the report information sent by the controlled device including the feedback information of the control execution instruction. In order to ensure the real-time synchronization of data between different devices in the industrial LAN, the information can be first transmitted to the time-sensitive network, and then the time-sensitive network will uniformly schedule and report it to the management system in the industrial LAN.

[0071] Figure 4 : is a flow chart of another communication method based on a converged industrial network provided in an embodiment of the present application. Figure 4 Steps S401 to S404 in the embodiment shown are Figure 1 Steps S101 to S104 in the illustrated embodiment are substantially the same and will not be described in detail herein. Figure 4 As shown, the method also includes the following steps:

[0072] In step S405 , the target controller receives the shared information sent by the industrial device via the industrial real-time Ethernet.

[0073] In step S406, the target controller sends the shared information to other controllers in the target industrial local area network via the industrial real-time Ethernet, or the target controller sends the shared information to other controllers in the target industrial local area network via the time sensitive network.

[0074] In some embodiments of the present application, the target controller can also receive shared information sent by industrial equipment through industrial real-time Ethernet, and then send the shared information to other controllers in the target industrial local area network through the industrial real-time Ethernet, or send the shared information to other controllers in the target industrial local area network through a time-sensitive network.

[0075] For example, the target controller can receive shared information including industrial data of the first industrial device reported by the transmitter or sensor, and send the shared information directly to the controller of the second industrial device in the industrial local area network through the industrial real-time Ethernet. Alternatively, if the target controller and the controller of the second industrial device cannot communicate in real time due to time asynchrony or other reasons, the target controller can first transmit the shared information to the time-sensitive network in the industrial local area network, and send the shared message to the controller of the second industrial device after the time-sensitive network completes the scheduling.

[0076] In some embodiments of the present application, any industrial LAN in the fused industrial network includes a time-sensitive network and an industrial real-time Ethernet, and the time-sensitive network is the backbone network. In other words, any industrial LAN in the fused industrial network can be constructed with the time-sensitive network as the backbone network, and the process management system and the controller communicate through the time-sensitive network. Furthermore, the industrial real-time Ethernet can also be integrated, and the controller and each industrial device communicate through the industrial real-time Ethernet. Different controllers can communicate directly or through the time-sensitive network.

[0077] Figure 5 Schematic diagram of the structure of the integrated industrial network architecture provided by the embodiment of the present application. Figure 5 As shown, the integrated industrial network architecture includes at least one industrial LAN and a wireless communication network. Each of the at least one industrial LAN includes a process management system, TSN (Time-Sensitive Networking) and at least one controller. The process management system interacts with industrial equipment through the controller, and the time-sensitive network is used to schedule messages in the industrial LAN. The TSN network is a backbone network that can achieve time synchronization and has both real-time and non-real-time communication functions. The controller can be a process control or logic control device. Different controllers can communicate directly between domains or communicate through the TSN network.

[0078] Furthermore, each industrial LAN also includes an industrial real-time Ethernet, which is used to provide a communication network for controllers and industrial equipment in the industrial LAN. Furthermore, the wireless communication network can be a 5G communication network, and the process management system is connected to the 5G gateway through a firewall. Slice-based 5G virtual private networks can be deployed between different 5G gateways to achieve inter-factory communication.

[0079] That is to say, the integrated industrial network architecture provided in the embodiment of the present application is an IT (Information Technology) / OT (Operational Technology) solution that integrates real-time Ethernet, TSN network and 5G network. It can not only improve the accuracy and reliability of industrial Ethernet data transmission, solve the data scheduling and real-time communication of data transmission between various devices in the industrial field, but also have the ability to connect and communicate (real-time and non-real-time communication) between remote sites, realize the problem of production linkage of equipment in different locations, and constitute a more powerful control network.

[0080] On the one hand, by building the process or logic control equipment (i.e., controller) of the field network on a real-time Ethernet network, the process or logic control equipment and the execution equipment (i.e., industrial intelligent devices, digital / analog / remote IO, industrial gateways or wireless IO and other industrial devices) can have real-time communication capabilities.

[0081] On the other hand, with the support of the TSN backbone network, a factory LAN with TSN as the backbone is built and a process management system is deployed, so that the process management system can maintain efficient communication (real-time and non-real-time communication) with the controller.

[0082] On the other hand, with the support of 5G virtual private networks, a 5G-based inter-factory wide-area Internet network is built, combined with a factory local area network with TSN as the backbone to realize the deployment of cross-domain process management systems.

[0083] Among them, since the current industrial sites are basically dominated by industrial real-time Ethernet, it is necessary to fully consider the current network status when building the industrial network architecture, and solve the industrial interconnection with minimal hardware changes and minimal cost. The integrated industrial network architecture provided by the embodiment of the present application continues the real-time Ethernet of traditional industry. Real-time Ethernet is mainly used for communication between controllers and devices, ensuring that the controller can control the operation of the device in real time, and can obtain the operating status and operation data of the device in real time, so as to control the operation of the device more accurately and efficiently.

[0084] Through real-time Ethernet, the accuracy and reliability of data transmission between controllers and devices can be achieved, and the real-time nature of data can be taken into account, thereby improving the control accuracy of the controller over the device and the accuracy of device data collection. As a process / logic processing unit, the controller also needs to maintain efficient communication with the process management system to ensure mutual cooperation between multiple controllers and improve production efficiency at industrial sites.

[0085] In view of TSN's superior time synchronization and unified scheduling characteristics, building a factory LAN with TSN as the backbone enables field network data transmission to have the same transmission time standard, which can improve the accuracy and reliability of data transmission and reduce the complexity of industrial field applications. It can not only realize the communication between the process management system and the controller, but also improve the coordination accuracy and execution efficiency between the controllers. At the same time, in the process of the controller feeding back / transmitting device status / equipment collecting data to the process management system, it can improve the data transmission efficiency, ensure the real-time nature of the data, and facilitate the more efficient operation of the process management system.

[0086] In addition, the factory LAN with TSN as the backbone can realize efficient interaction between the process management system and the controller and improve production efficiency, but it cannot realize cross-domain communication, and thus cannot realize cross-domain management and cross-domain. In the context of the open architecture of the Industrial Internet, industrial networks need to realize cross-network and cross-regional collaborative implementation control. Therefore, the integrated industrial network architecture provided in the embodiment of the present application provides 5G network communication between domains. With the support of 5G's virtual private network, a 5G-based inter-factory wide area interconnection network is constructed to realize cross-domain network interconnection, thereby realizing the cross-domain deployment of the process management system.

[0087] That is to say, the technical solution provided in the embodiment of the present application proposes a cross-domain integrated real-time transmission solution for industrial flow data, and constructs a workshop-level control network with industrial real-time Ethernet as the core and integrated field bus; the factory local area network with TSN as the backbone and the wide area public network based on 5G adopt a link connection framework with a unified model and a layered application message structure to achieve the integration of multi-source heterogeneous networks and support cross-network and cross-regional collaborative real-time control.

[0088] The process control system transmits the process control / logic control content to the local controller through the TSN backbone network, or transmits it to a controller in a foreign domain through the 5G+TSN transmission method. After receiving the content sent by the process control system, the controller performs corresponding operations to control equipment operation and data collection.

[0089] Data is collected from industrial intelligent devices, digital / analog / remote IO, industrial gateways, wireless IO and other devices to their respective devices. Real-time Ethernet is responsible for uploading the data to the controller, and the controller then transmits the data to the local process control system through the TSN backbone network, or transmits it to a foreign process control system through TSN+5G, realizing low-latency and highly reliable transmission of core data in the local area, while the 5G network is responsible for the wide-area end-to-end information proprietary channel.

[0090] All the above optional technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described one by one here.

[0091] The following is an embodiment of the device of the present application, which can be used to execute the embodiment of the method of the present application.
