Summary: | 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 |
