To solve the problems of complex industrial production data communication protocol and difficult communication between industrial equipment and cloud, an industrial internet of things (IIoT) gateway architecture is proposed. Firstly, aiming at the complexity and diversity of transport protocols, this paper proposes a multi-protocol data analysis method, which can parse data under various protocols, and converts it into MQTT protocol of the Internet of Things standard to realize data upload by unified protocol. Secondly, aiming at the problem of real-time reliability in protocol conversion, an asynchronous processing mechanism with breakpoint continuation capability is proposed to deal with concurrent tasks quickly, which ensures the real-time reliability of protocol conversion. Finally, on the basis of guaranteeing real-time reliability, a three-layer encryption method is proposed to realize highly secure data transmission. At the same time, The IIoT gateway architecture is implemented on hardware and software, and experiments are conducted on industrial process control equipment. The experimental results show that the proposed IIoT gateway architecture can effectively address the problem of data fusion between industrial system and cloud platform.
