Problems solved by technology

[0002] The traditional Internet of Things platform technology links multiple IoT devices through streaming processing on the cloud platform side based on data flow. This will cause massive data streams to converge on the platform for processing, causing great data processing pressure on the platform. At the same time, IoT devices pass through Various networks upload data to the platform. Once the network fails, the linkage function will not work
At the same time, various networks bring great delay and unreliability, making it impossible to realize real-time device linkage

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] like figure 1 In the described embodiment, a kind of local equipment linkage method of Internet of Things based on MQTT message-driven mechanism, specifically comprises the following steps:

[0031] (1) Arrange the device linkage rule engine in the cloud, and associate the rules configured by the rule engine with the selected edge gateway; the configuration method of the device linkage rule engine is:

[0032] (11) The internal message bus data sends the data to the data object segmentation module for processing, and the data object segmentation module divides the data into the form of key->value;

[0033] The data frame transfer format of the internal message bus is divided into attributes, events, and services. Their payload formats are all the same. The data of the internal message bus needs to be filtered first. Topic and data relea...

Abstract

The invention discloses an Internet of Things local device linkage method based on an MQTT message driving mechanism. The method specifically comprises the following steps: (1) arranging an equipmentlinkage rule engine at a cloud end, and associating a rule configured by the rule engine to a selected edge gateway; and (2) issuing configuration to an edge gateway end, carrying out edge calculationand rule engine logic linkage, specifically executing on an edge end, and when the network is unreliable, executing by local equipment according to user pre-configuration. The method has the beneficial effects that when the network is unreliable, local equipment still executes according to the pre-configuration of a user, so that the centralized processing pressure of a cloud platform is shared,and meanwhile, the local real-time reliable equipment linkage is realized without depending on a public network.

Description

technical field [0001] The present invention relates to the technical field related to the Internet of Things, in particular to a method for linking local devices of the Internet of Things based on an MQTT message-driven mechanism. Background technique [0002] The traditional Internet of Things platform technology links multiple IoT devices through streaming processing on the cloud platform side based on data flow. This will cause massive data streams to converge on the platform for processing, causing great data processing pressure on the platform. At the same time, IoT devices pass through Various networks upload data to the platform. Once the network fails, the linkage function will not work. At the same time, various networks bring great delay and unreliability, making it impossible to realize real-time device linkage. Contents of the invention [0003] The present invention aims to overcome the above-mentioned deficiencies in the prior art, and provides a local devi...
