Internet of Things data transmission method and system

Abstract

The embodiment of the invention provides an Internet of Things data transmission method and system. The method comprises the steps that a device end receives a control instruction sent to all device ends in a broadcast mode through a websocket connection pool by a cloud server, and if it is judged that the control instruction is used for indicating a local instrument to execute operation, the local instrument is controlled to execute operation corresponding to the control instruction, and an execution result is obtained; and the equipment end reports the execution result and data collected bya local instrument at regular time to the cloud server based on a websocket connection channel established between the equipment end and the cloud server. According to the embodiment of the invention,the data submission channel and the instruction issuing channel are separated, so that on one hand, the fault-tolerant capability can be improved; and on the other hand, the connection burden of theequipment end can be reduced. And on the other hand, the cloud server sends the broadcast to all the equipment ends, so that the coordination of the unified work of all the equipment ends is facilitated, and the operation synchronization performance can be improved for the cross-equipment-end operation.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of the Internet of Things, and in particular to a data transmission method and system of the Internet of Things. Background technique [0002] Instrument and equipment data communication has been widely used in all aspects of the Internet of Things, and the various aspects of industrial production are monitored through the Internet of Things system. The IoT system generally involves three main bodies: the device side, the cloud, and the client side. At present, the network architecture of the Internet of Things system generally adopts the network architecture form based on the websocket server. [0003] At present, the general processing method of the network architecture based on the websocket server is: establish a websocket service on the cloud server, each device end and the cloud server establish its own websocket connection channel, send data regularly, and receive the server’s r...

Problems solved by technology

[0005] (1) The fault tolerance of this processing method is poor. For example, once an error occurs in the execution of the instruction, it will cause the data report to fail, which will affect the normal work.

[0006] (2) This processing method is based on one connection for device data reporting and command issuance, and because the websocket long connection has a default timeout period, that is, if no message is sent f
