Abstract

The embodiment of the invention provides an Internet-of-things communication method and a cloud gateway. The method comprises the following steps: a data acquisition process: acquiring industrial datacollected by network equipment in a heterogeneous network; a protocol conversion process: analyzing the industrial data, and converting the industrial data with different communication protocols to OPC UA standard data, and then converting the industrial data to MQTT protocol data; a cloud transmission process: sending MQTT protocol data to cloud platform; a task scheduling process: triggering protocol conversion task generation after data acquisition process; triggering the generation of cloud transmission tasks after the protocol conversion process; storing the protocol conversion tasks andcloud transmission tasks in the task queue according to the generation time sequence, and triggering execution of the corresponding process by calling the non-blocking task scheduling function of thetasks in the task queue in turn. The embodiment of the invention realizes the communication transmission of the Internet-of-thigns in a non-blocking mode through a single gateway, and improves the real-time property of the communication of the Internet-of-things. Industrial data cloud services with different protocols are implemented.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of Internet of Things communication, and in particular to an Internet of Things communication method and a cloud gateway. 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 protocol standards...
