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

Abstract

The invention discloses an SDN-based intelligent production line multi-modal data interaction system and method. The system includes a device layer, a conversion layer, a network layer and a server layer. The device layer is composed of bottom devices, sensors and data acquisition nodes. It is used to collect the operation information of the equipment and summarize the data; the conversion layer is composed of distributed intelligent gateways, which are responsible for the format conversion of data and the interaction with the network layer; the network layer is built with a software-defined SDN network, which is used for the dynamic conversion of the conversion layer conversion protocol Configuration and data transmission path optimization; the server layer stores different protocol conversion installation packages through the establishment of the database, and stores the collected data and accesses user services. Based on the SDN network, the system decouples the device control plane and the data plane, realizes flexible control of network traffic, and mixes wired and wireless networks, making the data collection network system more flexible and convenient, and more suitable for current Production line status.
