[0035] The application layer is composed of the server, the first computer and the second computer.

[0036] The network layer consists of wireless APs, firewalls, three-layer switch groups, industrial switches, edge computing gateways, wireless WiFi-485 conversion gateways, and LoRa communication machine protocol converters.

[0037] The edge layer consists of data management unit, feeding unit, sorting unit and storage unit.

[0040] It is understood that the multi-protocol industrial interconnection system illustrated in this embodiment includes an application layer consisting of a server, a first computer, and a second computer; a network layer consisting of a wireless access point (AP), a firewall, a three-layer switch group, an industrial switch, an edge computing gateway, a wireless WiFi-485 conversion gateway, and a LoRa communication device protocol converter; and an edge layer consisting of a data management unit, a feeding unit, a sorting unit, and a storage unit.

[0041] In practice, the system network architecture is divided into three layers: application layer, network layer, and edge layer. The system integrates multiple communication protocols, basically covering most of the communication protocols of industrial communication, including various wired and wireless communication protocols such as Industrial Ethernet TCP / IP, Profinet, Profibus-DP, Modbus-TCP, Modbus-RTU, WiFi, and LoRa. Figure 1 Among them, Modbus-RTU is used between the data management PLC and the second LoRa data terminal, the second LoRa data terminal and the 485 sensor, and the 485 sensor and the switch; TCP / IP is used between the H750 gateway and the first industrial switch, and between the visual camera and the fourth industrial switch; Modbus-TCP is used between the feeding unit RFID and the second industrial switch, and between the storage unit RFID and the fourth industrial switch; Profinet is used between the unit modules of other edge layers and the industrial switches; and Figure 1 In the , other communication protocols of the application layer and the network layer are TCP / IP.

[0042] The application layer primarily consists of two industrial control monitoring hosts (the first and second computers) and a self-built private cloud platform (server). The cloud platform is connected to a Layer 3 switch via a firewall, enabling cloud-based storage, configuration design, and computational analysis of system data.

[0043] The network layer comprises network devices such as wireless access points (APs), firewalls, Layer 3 switches, industrial switches, edge computing gateways, wireless WiFi-485 conversion gateways, and LoRa communication protocol converters. The wireless APs access the system as external network devices. A 485-WiFi gateway is connected and configured to them. This allows necessary external sensor signal data to be transmitted to the internal network management or control unit via the external network, with appropriate firewall communication security policies in place, to complete detection and control tasks. The Layer 3 switch facilitates cross-segment communication between devices and is suitable for the industrial Internet communication requirements of large and medium-sized industrial sites with numerous devices and complex network architectures. The Layer 3 switch also provides cross-segment connectivity to the management platform control unit and various actuator units. The edge computing gateway, connected to one of the Layer 3 switches, integrates into the system and performs functions such as computing, managing, and distributing data collected and monitored by the edge layers. A communication configuration scheme for industrial wireless LoRa-485 has also been designed. Through LoRa master-slave gateways and protocol converters, remote wireless sensor data can be accessed through the system.

[0044] In the network layer, it should be noted that the three-layer switch group includes a first three-layer switch, a second three-layer switch and a third three-layer switch; the first three-layer switch is connected to the first computer, the firewall, the second three-layer switch and the third three-layer switch respectively; the second three-layer switch is connected to the second computer, the edge computing gateway, the first three-layer switch and the third three-layer switch respectively; the third three-layer switch is connected to the industrial switch, the first three-layer switch and the second three-layer switch respectively.

[0046] It should be noted that there are four industrial switches, namely the first industrial switch, the second industrial switch, the third industrial switch and the fourth industrial switch; the first industrial switch, the second industrial switch, the third industrial switch and the fourth industrial switch are all connected to the third three-layer switch; the first industrial switch is connected to the data management unit; the second industrial switch is connected to the feeding unit; the third industrial switch is connected to the sorting unit; and the fourth industrial switch is connected to the storage unit.

[0047] The edge layer primarily involves the control units of various management and execution mechanisms. The data management unit primarily manages all control system data, generates and distributes orders, and performs monitoring and alarm functions. The feeding, sorting, and warehousing units, distributed through commands issued by the application layer and the management platform, select material feeding methods, quantities, and materials, perform kinematic control of material sorting by classification function, and finally perform quality inspection, storage algorithm processing, and other process functions on the sorted products. Each of the three execution mechanisms is equipped with an integrated visualization machine to perform inspection and visual management of each unit's work tasks.

[0048] It should be noted that the data management unit includes: a data management PLC, a data management HMI and an H750 gateway; the data management PLC, the data management HMI and the H750 gateway are all connected to the first industrial switch.

[0053] 1. To address the many problems of traditional industrial field communication, such as the single mode and lack of intelligent control and management design units, the multi-protocol integrated industrial communication solution of this embodiment is suitable for the production line management and automation control needs of most industrial enterprises.

RFID is responsible for writing order and warehousing information; the barcode scanner scans bottle information; the encoder detects the belt's operating status and converts pulse data into distance and speed via the PLC; and the frequency converter controls the three-phase AC asynchronous motor. Combined with an intelligent industrial vision inspection system, this system enables rapid functional classification and quality inspection of production line products.
