Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.

The following detailed description of exemplary embodiments of the disclosure refers to the accompanying drawings.

In order to enable the industrial internet to realize high-time-precision Network control information transmission inside production lines, between production lines and between a control Network and an information Network, the embodiment of the disclosure realizes Network information processing of the industrial internet by building a Wireless Local Area Network (WLAN) with TSN capability.

The TSN (Time-sensitive networking) technology is mainly responsible for the formulation and application of the underlying protocols driven by the IEEE802.1 TSN working group, which can ensure that information is transmitted from one point to another in a fixed and predictable Time. Due to the characteristics of high-precision time synchronization, personalized and accurate flow scheduling, an intelligent network management mechanism and the like, the TSN technology can be widely applied to a service data transmission scene with the requirements of interconnection and intercommunication, deterministic high-quality transmission and full-service bearing in a network.

The functional architecture of the TSN Network follows SDN (Software Defined Network) technology, and conforms to current protocol requirements (ieee std802.1qcc), and the configuration models are divided into three types, namely, a fully centralized configuration model, a hybrid configuration model, and a fully distributed configuration model. Considering that a deployment architecture under an industrial internet network scene needs to be fused with an SDN architecture, the embodiment of the present disclosure selects to adopt a fully centralized configuration model (CNC centralized control model) to realize the construction of a TSN wireless network.

Referring to fig. 1, the TSN network functional architecture includes three functional modules, namely, a control management module 11(CNC, CUC), a Bridge module 12(Bridge), and a terminal module 13 (Talker/Listener).

The control management module 11 includes a centralized user configuration module 111(CUC) and a centralized network configuration module 112 (CNC). The CUC (Centralized User Configuration) is responsible for translation of network requirements by users and inter-domain cooperation of network information and equipment Configuration; the CNC (Centralized Network Configuration) is in charge of realizing the functions of monitoring and managing the device, discovering the Network topology, monitoring and optimizing the traffic, modeling the service, issuing the scheduling model, and the like, in the same TSN domain.

The Bridge module 12 includes one or more bridges (bridges), which may be two-layer Bridge devices of different forms, supports the relevant online measurement protocol, and sends the relevant status to the control management module 11 in real time, so as to implement real-time network-wide monitoring and dynamically adjust the relevant configuration according to the network requirements and status.

The terminal module 13 includes a sending unit (Talker) and a receiving unit (Listener), where the Talker or Listener may be an industrial device or an application system, and has the capability of accessing the TSN network, and supports online measurement and operation and maintenance related protocols, so as to implement topology discovery, state monitoring, and network service optimization over the whole network.

In order to build an industrial internet with a TSN function, the embodiment of the present disclosure implements the architecture shown in fig. 1 through a WLAN networking device. WLAN is a wireless local area network technology defined by IEEE 802.11 working group, and enterprise networks usually adopt FAT AP (FAT AP) architecture or FIT AP (thin AP) architecture for WLAN networking. The AP (Access Point, Access Point device) is a basic network transmission unit in the WLAN system. The FAAP, namely a FAT AP framework, has the management and self-configuration functions of routing, DNS, DHCP and the like, the AP equipment can work independently, the upper layer does not have uniform control equipment, a centralized network configuration management unit is lacked, and the centralized collection of network demand information and the centralized setting of network information control of the TSN technology are difficult to realize in FAAP networking. The FIT AP, i.e. the thin AP architecture, refers to a networking mode in which an AP device has no management and self-configuration functions, only has a wireless access function, and needs to work in conjunction with an AC (access Point Controller) device. The FIT AP architecture can structurally adapt to the centralized network configuration management unit deployment requirement existing in the configuration architecture of the TSN mainstream, so that the inventor of the application builds a WLAN system (wireless local area network system) with the TSN capability by improving equipment on the basis of the traditional FIT AP architecture.

Referring to fig. 2, the wireless local area network system 200 may include:

the wireless access controller 21(AC device) includes a centralized user configuration module 211(CUC) and a centralized network configuration module 212(CNC), the centralized user configuration module 211 is configured to receive the network requirement information and send the network requirement information to the centralized network configuration module 212, and the centralized network configuration module 212 is configured to generate a TSN data transmission configuration instruction according to the network requirement information in the TSN operating mode.

The transmission module 22 is connected to the wireless access controller 21, and includes an access point device 221(AP device), where the access point device 221 includes a TSN control protocol stack, and the transmission module 22 is configured to receive a TSN data transmission configuration instruction and transmit data according to the TSN data transmission configuration instruction.

The application module 23, which connects the transmission module 22 and the radio access controller 21, includes a sending unit 231(Talker) and a receiving unit 232(Listener), where the sending unit 231 is configured to output the network requirement information to the radio access controller 21, and the receiving unit 232 is configured to receive the data transmitted by the transmission module 22.

In the embodiment of the present disclosure, the radio access controller 21 is centrally deployed in the enterprise network, and centrally manages one or more transport modules 22 by connecting the transport modules 22 through tunnels. In one embodiment, the radio access controller 21 may manage the transmission module 22 through a netconf interface, and manage the operation mode configuration and TSN protocol family processing of the transmission module 22 through a centralized network configuration module 212 (CNC). The centralized user configuration module 211(CUC) is configured to receive the network requirement information transmitted by the sending unit 231(Talker) in the application module 23, collect user information, and receive a resource application from a user to the network.

In the embodiment of the present disclosure, the radio access Controller 21, i.e., an AC (access Point Controller) device, is further provided with a centralized user configuration module 211(CUC) and a centralized network configuration module 212(CNC) in addition to the capability of the AC device in the conventional FIT AP architecture, so as to implement the TSN capability.

Referring to fig. 3, according to the ISO/OSI seven-layer network model, the radio access controller 21 has two-layer (data link layer) encryption, WMW QoS, and management of out-of-frame 802.11 base protocol functions, three-layer (network layer) mobile IP, IP specification (IP Sec), and 802.1x protocol analysis functions, four-layer (transport layer) TCP/IP, UDP, and DPI protocol analysis functions, five-layer (session layer) channel (Sockets) function, six-layer (presentation layer) SSL, and TSL functions, seven-layer (application layer) DHCP, NTP, SNMP, and Portal functions, and a centralized user configuration module 211(CUC) and a centralized network configuration module 212(CNC) are provided in the seventh layer.

Through the improvement of the wireless access controller 21, the wireless lan system of the embodiment of the present disclosure not only has TSN capability, but also can simultaneously operate in a normal wireless network (WiFi) operating mode.

In one embodiment, the centralized user configuration module 211(CUC) further determines a network operation mode according to the network requirement information, and sends the network operation mode and the network requirement information to the centralized network configuration module 212(CNC), wherein the network operation mode includes a TSN operation mode and a non-TSN operation mode. The wireless lan system 200 may form a WiFi network and a TSN network tightly coupled, and select an FIT AP mode (non-TSN operating mode) or a TSN operating mode according to a service condition, to reasonably carry various services, so that the WiFi network can be more flexibly deployed and used, and the construction cost is reduced.

In one embodiment, the transmission module 22 may include an access point device 221(AP device). The access point device 221 may include a TSN control protocol stack to execute TSN data transmission configuration instructions sent by the centralized network configuration module 212 (CNC).

Referring to fig. 4, in an embodiment, an access point device 221(AP) includes a first layer antenna, a network card (physical layer), and management frame and control frame functions of a second layer (data link layer), and a TSN protocol stack 2211 is further disposed in the second layer, and a built-in TSN protocol family (802.1Qbv, 802.1Qcc, 802.1Qbu, 802.1AS, 802.1CB) may support traffic shaping, resource management, traffic preemption, time synchronization, and high availability. Meanwhile, the access point device 221 has three layers (network layers) of IP packet encapsulation and tunnel construction functions.

In the FIT AP mode, the AP device has no routing function, and only the AC device has. Because the AP has no routing function and no capability of more than three layers (only the AC device is available), the data plane traffic flows will bypass to the AC device for interaction, which results in an uncertain transmission time, which causes a section of uncertain network transmission, and affects the performance of the TSN network. Therefore, in an embodiment of the present disclosure, a four-layer (transport layer) function module, i.e., a packet parsing module 2212, is disposed in the access point device 221(AP device) to implement a minimal basic protocol layer function such as TCP/IP and UDP packet parsing, so that the access point device 221 has a function of routing and forwarding. Therefore, the traffic of the AP device can be forwarded to the TSN network through the local interface or directly interwork with other devices in the AP device and the transmission module 22, or directly transmit data (not required by the network) with the application module 23, and the built-in TSN protocol family (802.1Qbv, 802.1Qcc, 802.1Qbu, 802.1AS, 802.1CB) can support traffic shaping, resource management, traffic preemption, time synchronization and high availability.

In addition, the access point device 221 has four-layer capability, and may be suitable for OPC UA (OLE for Process Control Unified Architecture) to implement the fusion of the TSN technology and OPC UA. The TSN technology mainly solves the problems of time synchronization, data scheduling and network configuration of a data link layer, and the OPC-UA focuses on 5-7 layers and solves the problem of semantic analysis by establishing connection and using a unified information model specification.

The access point device 221 shown in fig. 4 and the radio access controller 21 shown in fig. 3 may implement wireless transmission with the application module 23, but in some scenarios, the application module 23 is a terminal without wireless capability, and at this time, an STA device may be set in the transmission module 22.

Referring to fig. 5, in one embodiment, the transmission module 22 may include a plurality of AP devices 221 and one or more wireless terminals 222. AP device 221 and wireless terminal 222 may communicate with each other.

The wireless terminal 222 is also called sta (station) Equipment or UE (User Equipment), and has a network connection function. In the embodiment of the present disclosure, a TSN protocol conversion module 2221(TSN Translation, TT module) is provided in the wireless terminal 222, and is used for implementing ethernet and TSN network protocol Translation, so as to implement interconnection and intercommunication between a wireless network and a wired network.

The wireless terminal 222 may be a client capable of connecting a wireless network and a wired network, and may be a computer equipped with a wireless network card or a smart phone with a WiFi module. In one embodiment, the wireless terminal 222 may connect to the implementing device of the application module 23 through the TSN protocol conversion module 2221 by using a wired connection, so as to provide the application module 23 without wireless communication capability with TSN function through the wired connection.

When the wireless terminal 222 is disposed in the communication module 22, the wireless terminal 222 and the access point device 221 together form a TSN Bridge (TSN Bridge), and the communication module 22 may include one or more TSN bridges. A centralized network configuration module 212(CNC) in the radio access controller 21 manages the operating mode configuration of the wireless terminal 222 and the access point device 221.

When the sending module 231 in the application module 23 has the wireless communication capability, the network requirement information may be directly sent to the radio access controller 21, and when the sending module 231 does not have the wireless communication capability, the network requirement information may be sent to the wireless terminal 222, and the wireless terminal 222 sends the network requirement information to the radio access controller 21. When the receiving module 231 has the wireless communication capability, the data may be directly received from the ap device 221, and when the receiving module 231 does not have the wireless communication capability, the data may be received by the wireless terminal 222.

In the embodiment of the present disclosure, the sending module 231 and the receiving module 232 in the application module 23 are only virtual function modules. In practical applications, the method can be implemented by one or more terminals. For example, one terminal in the system 200 may include both the transmission module 231 and the reception module 232, and the other terminal may include only the transmission module 231 or only the reception module 232. In addition, one or more sending modules 231 and one or more receiving modules 232 may be disposed on a terminal and in the system 200, and the number of the sending modules 231 and the number of the receiving modules 232 may be the same or different.

The sending unit 231 is mainly used for sending the network requirement information, and the network requirement information sent by the sending unit 231 may be generated by itself or received from a connected enterprise network, an external application, a wired TSN network, and the like. The receiving unit 232 is configured to receive the data output by the transmission module 22, and after the receiving unit 232 receives the data, the data may be applied locally, or the data may be transmitted to an enterprise network, an external application, a wired TSN network, or the like connected thereto. In one embodiment, the same network device may include both the sending unit 231 and the receiving unit 232, the number of the sending unit 231 and the number of the receiving unit 232 may be one or more, and the number of the sending unit 231 and the number of the receiving unit 232 may be equal or different. The network device can be connected to an enterprise network, an external application and a wired TSN network on the one hand, and to the wireless access controller 21 on the other hand, and is used for realizing data transmission between a wireless local area network system (WLAN system) with TSN capability and the enterprise network, the external application and the wired TSN network.

Referring to fig. 6, a terminal device 61(Talker) provided with a transmitting unit connects the enterprise network and the wired TSN network, has a wireless communication capability, and directly transmits network demand information to the CUC module 211 in the AC device 21. Meanwhile, when the terminal device 62(Talker/Listener) provided with the transmitting unit and the receiving unit does not have the wireless communication capability, the STA device 222 provided with the TT module may transmit the network requirement information to the CUC module 211 of the AC device 21. That is, when there is a new data stream, the CUC module 211 may sense through Talker and Listener, collect user information, receive a resource application of a user to a network, and configure the user, where the Talker may be initiated by the STA device 222 to perform an operation (send network requirement information), or initiated by the terminal device 61 to perform an operation.

The CUC module 211 indicates Talker and Listener to notify the CNC module 212 of the network requirement information, and selects a conventional FIT AP mode (non-TSN operating mode) or a TSN FIT AP mode (TSN operating mode) according to the service condition, and notifies the CNC module 212 of the result of the operation mode selection. The CNC module 212 performs corresponding operation according to the obtained information, and issues the obtained network configuration parameters to the relevant TSN Bridge (TSN Bridge) in the communication module 22, respectively, and the AP device and the STA device in the TSN Bridge transmit data to the receiving module 232 using corresponding strategies when forwarding the data frame according to the received configuration information. In fig. 6, the terminal apparatus 63 is provided with a receiving unit, functioning as a Listener. The terminal device 62 may also act as a Listener. When the terminal device 62 or the terminal device 63 has the wireless communication capability, data can be obtained from the AP device 221, and when the terminal device does not have the wireless communication capability, data can be obtained from the STA device 222 having the TT module. In a TSN bridge, STA device 222 and AP device 221 may communicate with each other (AP device 221 has four-layer capabilities). The communications module 22 may include a plurality of TSN bridges.

In the wireless local area network system of the embodiment of the disclosure, under an FIT AP architecture, CNC and CUC control management units adapted to TSN network capacity are added in an AC device, a TSN FIT AP mode (namely, a TSN working mode) is defined, a TSN related protocol stack and functions are modularized, and the TSN network capacity is respectively built in the AC device and the AP device in a modularized manner, so that the WLAN network of the AC + AP architecture bears the TSN, the TSN deployment can be flexibly adapted, the deployment cost is reduced, and the WLAN network is easier to have the TSN capacity.
