[0021] In order to make the person skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.

[0022] The embodiments of the present application provide a method for industrial equipment networking, as shown in Figure 1 The method for industrial equipment networking specifically includes steps S101-S104:

[0023] S101, establish network connection between a plurality of active identification devices, and construct a WIFI-Mesh ad hoc network.

[0024] Specifically, the active identification device is installed in the industrial equipment to be transformed, and the active identification device is powered on; network connection is established between each powered-on active identification device through the AP hotspot function of the active identification device, and a WIFI-Mesh ad hoc network is obtained; wherein each active identification device is an ad hoc network node.

[0025] Figure 2 A WIFI-Mesh ad hoc network diagram provided by the embodiment of the application is shown in FIG. 1. Figure 2 As shown in FIG. 1, compared with the traditional wireless network, the WIFI-Mesh ad hoc network adopts a tree topology structure, and is a mobile broadband multimedia communication system designed based on a new "wireless mesh network" concept. All nodes of the system can realize real-time interaction of multimedia information such as multi-channel voice, data, and image under non-line-of-sight and fast movement conditions, using the distributed network architecture of the centerless ad hoc network. The overall system is convenient to deploy, flexible to use, simple to operate, and easy to maintain. It can provide a network that is easy to deploy, automatically networked, and self-repaired. It can deploy nodes in a larger range without deploying Wi-Fi infrastructure. Based on this network topology structure, it can be expanded to thousands of nodes at most. The more nodes, the more stable the communication quality. The wireless long-distance WiFi ad hoc network can use mesh technology, and is composed of a group of mobile nodes with wireless transceiver devices, forming a temporary multi-hop autonomous system. It does not depend on infrastructure, has the characteristics of temporary networking, no control center, and strong anti-destruction.

[0026] The application designs an active identification device with WIFI-Mesh ad hoc network function. A plurality of active identification devices can form a star-shaped distributed network through the ad hoc network mode, access the industrial internet system through the center node, and solve the current problems of active identification terminal networking difficulty, unstable field network, low communication rate, and the like. In the ad hoc network, all active identification terminals have AP hotspot function and act as Agent roles. The Agent node is both a branch node in the star-shaped network node and a device entity accessing the network. It needs to execute the command sent by the Controller node, and periodically reports the network metric and capability information to the Controller node. The Agent node can indirectly connect to the Controller node through other Agent nodes.

[0027] S102, determine the center node of the WIFI-Mesh ad hoc network.

[0028] Specifically, the transmission power of each mesh node in the WIFI-Mesh ad hoc network is acquired. The mesh node with transmission power greater than a preset threshold is selected as the center node.

[0029] As a feasible implementation, the node with the strongest transmission power is selected as the center node, as the main node accessing the public network, and undertakes the Controller role of the WIFI-Mesh ad hoc network, and provides the access function in the network for other active identification devices supporting the Mesh ad hoc network. The Controller node receives network metrics and device capability information, and through certain analysis and calculation, unifies the functions of the entire Mesh network, such as channel, topology structure, and client roaming. The Controller node also sends control commands to the Agent node to improve the load balancing in the network or control the management of other functions. The Controller node can be a separate device, or can be integrated with the Controller+Agent.

[0030] Further, if a new active identification device is added, the new active identification device is added as an Agent node to the WIFI-Mesh ad hoc network, so that the center node Controller and the new active identification device Agent are mutually discovered and connected. Then the network information and the capability information of the new Agent node are acquired, and the node information of the new Agent node is configured according to the network information and the capability information; wherein the capability information includes whether the new Agent node supports 2.4G, 5G, and the number of supported SSIDs.

[0031] As a feasible implementation, when an active identification device is added as an Agent node to the network, the center node Controller and the active identification device Agent are mutually discovered through IEEE 1905.1 protocol initialization. The Controller queries the network information and the wireless capability (whether supporting 2.4G, 5G, and the number of supported SSIDs) of the connected Agent through the protocol, and according to the information, the Controller decides how to configure the Agent.

[0032] Further, based on the automatic configuration process in the IEEE 1905.1 protocol, the node information of the new Agent node is configured; wherein the node information at least includes any one or more of the following: hotspot SSID, password, metric, network topology configuration.

[0033] S103, access the public network of the industrial internet platform by the center node, so that the active identification device is connected with the industrial internet platform through the center node.

[0034] Specifically, the center node is configured as a controller role, and accesses the public network of the industrial internet platform. The active identification device is set as an Agent role, accesses the center node through the relay nodes of various levels of Agents, and connects with the industrial internet platform through the center node.

[0035] As a feasible implementation, in the WIFI-Mesh self-organizing network in the initial stage of networking, the center node accessing the Ethernet needs to be configured as a controller role. After the configuration of the Controller device is completed, new Agent nodes are imported and information is configured to achieve the purpose of expanding the network. After the active identification device is powered on, it will actively broadcast its own hotspot SSID, and establish a connection with the center node according to the WPS protocol and using the WPA2 protocol.

[0036] Further, each active identification device as an AP hotspot will poll the sub-devices connected to it based on a preset period, obtain the signal strength of each sub-device, and periodically select channels according to the signal strength. The center node Controller obtains the channel information currently selected by each active identification device, and configures the preferred channel and transmission power and other information of each Agent node according to the channel information.

[0037] S104, collecting operation data of the industrial equipment to be transformed by the active identification device, and remotely intelligently transforming the industrial equipment to be transformed according to the operation data.

[0038] Specifically, according to the type of the active identification device in the industrial equipment to be transformed, the type of operation data to be collected is determined. The active identification device collects the type of operation data to be collected to obtain the operation data of the industrial equipment to be transformed; and according to the remote configuration strategy, the collected operation data of the industrial equipment to be transformed is periodically or real-time reported, so that the industrial internet platform intelligently transforms the industrial equipment to be transformed.

[0039] As a feasible implementation, the active identification device collects the state of the old equipment in the industrial field after connecting with the industrial internet platform. According to different types of equipment, various types of operation data such as voltage, current, switch state and other data can be collected. According to the remote configuration strategy, the state of the currently connected old equipment can be periodically / real-time reported to realize the intelligent transformation of the old equipment. The active identification device as an Agent node can enhance its communication capability through a high-gain antenna module, can increase the transmission power in a harsh electromagnetic environment, and can maintain channel stability through spread spectrum and frequency modulation to solve the problem of unstable field network and communication easily affected by interference.

[0040] Further, when a certain active identification device in the WIFI-Mesh self-organizing network fails and cannot undertake the Agent node function, the child device of the active identification device detects the network disconnection, searches all hot spot SSIDs of the nearby neighbors, until the most stable active identification device is found and connected, thereby re-accessing the WIFI-Mesh self-organizing network.

[0041] The failure of a certain active identification terminal does not affect the stability of the self-organizing network system, and the more the number of active identification terminals in the intelligent field is changed, the more stable the star-shaped distributed network will be, and the communication quality is more stable.

[0042] In addition, the embodiment of the application further provides an active identification terminal for industrial equipment networking, as shown in the figure.
