Abstract

The invention is applicable to the technical field of water quality detection, and provides a water quality abnormity detection method and device and terminal equipment. The method comprises the following steps of acquiring time sequence measurement data within a first duration of a to-be-detected water area monitoring node, and inputting the time sequence measurement data into a UV254 predictionmodel based on a recurrent neural network (RNN) to obtain UV254 prediction data in the first duration of the to-be-detected water area monitoring node; computing a difference by using the UV254 measurement data and the UV254 prediction data, obtaining a residual error, and generating a confidence interval according to the residual error distribution; if the residual error is within the confidenceinterval, determining as a normal point; if the residual error is not within the confidence interval, determining as an abnormal point; and representing a cumulative probability of the water quality abnormity probabilities in a second time window for all measurement moments in the second time window in the first duration, and if the cumulative probability is larger than a preset probability threshold value, judging that a water quality abnormality event occurs in the second time window. According to the method, the device and the terminal equipment, the water quality abnormity detection effectis greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of water quality detection, and in particular relates to a method, device and terminal equipment for abnormal water quality detection. Background technique [0002] China is short of water resources, and the per capita water resources are only a quarter of the world's average level. However, some water resources in my country are polluted to varying degrees. Among them, organic pollution incidents account for a large proportion of river water pollution incidents, which affect urban water supply. . UV254 is an important control parameter to measure the organic matter in water. It can effectively reflect the content of organic matter in water. It has the characteristics of fast detection speed, high sensitivity to organic matter, and no reagents. It can effectively detect the content of organic matter in rivers, so it is suitable for use It is used in the detection of abnormal water quality of rivers, especial...
