Research on Real-time Data Transmission between IoT Gateway and Cloud Platform based on Two-way Communication Technology

Abstract

To realize the real-time two-way communication between the IoT gateway and the cloud platform and improve the transmission efficiency, this paper adopts the designed open IoT platform, uses the Node.js server as the operating platform, and uses the Redis database fast access technology. The design is based on Modularized processing of real-time two-way communication system of Internet of Things gateway and resource platform based on Socket.IO communication protocol. Compared with the traditional Internet of Things communication protocol, the advantage of Socket.IO is that only a handshake between the client and the server is needed to quickly establish a Socket two-way channel, which can realize the real-time two-way transmission of data and effectively save broadband resources. Thereby improving the system's real-time update efficiency of the data model, and ensuring the stability and reliability of the system. For the system function and performance test, the experimental results show that the use of Socket.IO two-way communication technology can realize the simultaneous update of the physical model of the IoT gateway and the virtual model of the IoT cloud platform, and effectively improve the data transmission efficiency of the system.
