The disclosure provides an MQTT-based distribution Internet of Things system and a method thereof. The system includes: a sensing ring including a plurality of data acquisition and monitoring devices and a sensing control module provided in a distribution network; an application ring including a plurality of application servers and an application control module; a communication ring including at least one communication module, each communication module being connected with the application control module and a corresponding sensing control module respectively. The application ring is configured to issue an application request, so that the sensing ring controls a distribution device in the distribution network according to the application request and acquires device data of the distribution device, and the sensing ring feeds the device data back to the application ring; and/or the sensing ring is configured to sense and acquire the device data of the distribution device, and send the device data to the application ring, so that the application ring performs data management, data processing, data analysis, data monitoring and data pre-warning on the device data. The method has a beneficial effect that the constructed distribution Internet of Things system is simpler.

MQTT-based distribution internet of things system and method thereof

The disclosure provides a method, a device and a system for fault detection. The fault detection method includes following steps: acquiring interactive data generated during a working process of a target Internet of Things system, and generating data to be detected based on the interactive data; detecting whether the data to be detected is fault data or not, and performing an emotion analysis on the data to be detected which is judged as the fault data to obtain a corresponding emotion label; and extracting a corresponding fault type from a preset fault emotion mapping table based on the emotion label and outputting the fault type. In this disclosure, the interactive data is analogized to human emotions, and the faults are accurately found through the emotional analysis on the data, thereby achieving the fault detection of the Internet of Things system in a convenient, flexible and accurate manner.
