MQTT (Message Queue Telemetry Transport) is an open OASIS and ISO standard (ISO/IEC PRF 20922) lightweight, publish-subscribe network protocol that transports messages between devices. The protocol usually runs over TCP/IP; however, any network protocol that provides ordered, lossless, bi-directional connections can support MQTT. It is designed for connections with remote locations where a "small code footprint" is required or the network bandwidth is limited.

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.

Error information pushing method, device and equipment and readable storage medium

ActiveCN111107080ATransmissionMQTTReal-time computing

The invention discloses an error information pushing method, device and equipment and a readable storage medium. The method disclosed by the invention is applied to a server, and comprises the following steps: obtaining error information in a browser; determining the category of the error information and a client corresponding to the category; and pushing the error information to the client through an MQTT protocol, and displaying the error information at the client. According to the invention, the client can receive the error information pushed by the server in real time; according to the method and the device, the feedback efficiency of the error information in the browser is improved, so that technicians of each client can obtain the error information in time and repair code errors running in the browser in time according to the error information, the repair duration can be shortened, and the repair efficiency is improved. Correspondingly, the invention also discloses an error information pushing device and equipment and a readable storage medium, which also have the above technical effects.
