Problems solved by technology

Most of the current technologies are dedicated one-to-one protocol gateways. When converting between any two different protocols, a dedicated gateway is required, which is very inconvenient in the current complex intelligent production line heterogeneous network communication.
Moreover, it is necessary to write different gateway programs for different devices, and even need to add a private protocol in the gateway to enable the successful access of the device, which greatly affects the overall compatibility of the system
In addition, it is necessary to make corresponding hardware access ports according to the equipment, which not only prolongs the development cycle but also increases the maintenance cost of the system

Embodiment 1

[0034] This embodiment provides an SDN-based multi-modal data interaction system for intelligent production lines. The system includes four layers: equipment layer, conversion layer, network layer, and server layer. The equipment layer includes terminals and data of intelligent production lines. collection node. The terminal equipment mainly involves three aspects: product, processing, and transportation. The product aspect includes raw material addition and finished product packaging; the processing aspect includes processing equipment such as robotic arms and lathes; the transportation includes the movement and status detection of the production line. Due to the different manufacturers of each device, the types of communication protocols used for underlying data transmission are different. At present, there are more: ModbusTCP, ModbusRTU, OPCUA, RFID, Zigbee, Wifi, etc. Firstly, the equipment in the production line is divided according to function and area, and some areas or...

Abstract

The invention discloses a software-defined network (SDN) based multi-mode data interaction system and method for an intelligent production line. The system comprises an equipment layer, a conversion layer, a network layer, and a server layer, wherein the equipment layer comprises underlying equipment, sensors and data acquisition nodes, and is used to acquire equipment operation information and carry out data summarization; the conversion layer comprises distributed intelligent gateways, and is used for data format conversion and interaction with the network layer; the network layer is erectedthrough an SDN, and is used for dynamic configuration of a conversion protocol of the conversion layer and data transmission path optimization; and the server layer stores different protocol conversion installation packages through establishment of a database, and is used for storage of acquired data and access of user services. The system disclosed by the invention has the advantages that an equipment control plane and a data plane are decoupled based on the SDN, so that network traffics can be flexibly controlled; and a wired network is mixed with a wireless network, so that a data acquisition network system is more flexible and convenient, and is more applicable to the current production line situation.
