Abstract

The present invention discloses an outlier analysis-based device anomaly detection method and system. The method includes the following steps that: a plurality of monitoring data in a sewage treatment process are collected; the plurality of monitoring data are detected, so that outliers in the monitoring data and the distribution status of the outliers are obtained; and the outliers are screened and replaced according to the distribution status of the outliers; the anomaly of a device is determined according to the distribution status of the replaced outliers; and the abnormal status on the device is fed back. According to the outlier analysis-based device anomaly detection method and system of the invention, the anomalies of the monitoring data are sequentially analyzed, so that the outliers in the monitoring data can be obtained; and the distribution status of the outliers is further analyzed, so that the anomaly of the device can be detected, and therefore, detection accuracy and real-time performance can be improved.

Description

technical field [0001] The invention relates to the technical field of equipment control, in particular to a method and system for detecting equipment abnormality. Background technique [0002] The normal operation of sewage treatment equipment is the key to ensure process stability and effluent quality up to standard. The "Water Pollution Prevention and Control Action Plan" ("Water Ten Measures") issued by the State Council in 2015 put forward higher requirements for sewage treatment. It is imperative to promote the development and application of sewage treatment equipment, management and control technologies around the water quality of sewage treatment. At present, the research on sewage treatment control technology mainly focuses on closed-loop control, among which PID control can better realize the control of water plant equipment, but its adaptability to the environment is poor, and there is a lack of equipment abnormal alarm measures, and at the same time, it is affec...
