Intelligent cloud gateway of industrial IoT (Internet of Things) and communication method of gateway

Abstract

The invention provides an intelligent cloud gateway of the industrial IoT and a communication method of the gateway. The gateway comprises a data collection module, a protocol analysis and conversionmodule and a cloud transmission module; the data collection module obtains industrial data collected by network equipment in the heterogeneous network; the protocol analysis and conversion module analyzes protocols of the industrial data, converts the industrial data with the different communication protocols into OPC UA standard data, and further converts the obtained OPC UA standard data into MQTT protocol data; and the cloud transmission module transmits the MQTT protocol data to a cloud platform. Thus, the industrial data with the different protocols is sent to the cloud via the single gateway, different network device access schemes are provided, and the difficulty in transmitting the multi-protocol industrial data to the cloud in the heterogeneous network is solved; and the securityof data transmission is ensured comprehensively in the network, transmission and application layers, and a complete security guarantee system is formed.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technologies, and in particular to an industrial Internet of Things intelligent cloud gateway and a communication method thereof. Background technique [0002] Industrial data communication has been widely used in all aspects of industrial production, and all aspects of industrial production are monitored through industrial communication systems. At present, there are two main ways to access industrial data, one is to transmit to the local computer for control through the serial port or bus, and the other is to upload to the cloud server through the network and use the remote terminal for data access. Although the Internet of Things is currently widely used in various fields, there is no unified interface for Internet of Things data access. At present, there are many data acquisition protocols for sensor networks, especially traditional industrial sensor networks, and the pro...
