Abnormal state detecting method and system for equipment in internet of things

Abstract

The invention discloses an abnormal state detecting method and system for equipment in the internet of things. The method comprises the following steps of receiving equipment operation state detection information, analyzing the detection information, obtaining equipment states of the equipment, judging whether the similarity between the equipment states and any stored equipment state in state space is in a preset range, judging that the equipment is in normal operation if the similarity is in the preset range and giving out virtual alarm information that the equipment may be abnormal if the similarity is not in the preset range. According to the abnormal state detecting method and system, the equipment operation states are judged by taking factors into consideration instead of only relying on read values of a sensor. Thus, the abnormal state detecting method and system are accurate in judgment. Furthermore, a plurality of normal operation states are previously stored, the current equipment operation states are compared with the normal operation states, and the false alarm ratio is effectively reduced.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to a method and system for detecting abnormal states of equipment in the Internet of Things. Background technique [0002] The Industrial Internet of Things integrates various acquisition or control sensors or controllers with perception and monitoring capabilities, as well as technologies such as ubiquitous technology, mobile communication, and intelligent analysis, into all aspects of the industrial production process, so as to upgrade traditional industries to intelligence. goals of the new stage. In terms of application form, the application of industrial Internet of Things has the characteristics of real-time, automation, embedded (software), security, and information interoperability and interconnection. [0003] There are many devices involved in the Internet of Things, and it is usually necessary to monitor the operating status of the devices in order to detect abnorma...

AI Technical Summary

Problems solved by technology

[0004] Based on this, it is necessary to provide a method and system for detecting abnormal state of equipment in the Internet of Things with a low false alarm rate in view of the problem that the traditional technology simply relies on the reading value of the equipment sensor to judge the equipment operation status, which is easy to cause false alarms.
