Method and system for automatically generating pressure flow monitoring threshold value of water supply system

Abstract

The invention provides a method and a system for automatically generating a pressure flow monitoring threshold value of a water supply system. The method comprises the following steps: selecting historical data of each sensor in a latest period of time for statistical analysis; performing abnormal value elimination processing on the data; performing periodical inspection on the data processed in the step S2, and distinguishing periodicity; selecting a sensor with strong periodicity, and verifying data at each moment until a threshold generation condition is met; performing statistical analysis on the data by using a statistical 3 sigma rule, and optimizing a threshold value; for other periodic sensors, a constant threshold value is generated; and repeating the contents on the latest historical data by taking day as a period to generate a latest threshold value. According to the method for generating the threshold value, disturbance caused by abnormal data is fully considered, input data are filtered through three elimination methods, smoothing processing is carried out on the data at each moment, and meanwhile in order to guarantee the reliability of the input data, the data quantity at each moment is checked and supplemented.

Description

technical field [0001] The invention belongs to the technical field of pressure and flow threshold setting of a water supply pipe network, and in particular relates to a method and system for automatically generating a pressure and flow monitoring threshold of a water supply system. Background technique [0002] At this stage, the water company usually adopts the following methods for judging the working conditions of the water supply network. First, the administrator sets corresponding alarm thresholds for each measuring point through the monitoring center software according to the surrounding water supply conditions. When the pressure or flow exceeds the limit, the monitoring equipment will The alarm information is uploaded to the monitoring center, and the water supply department handles it in a timely manner to ensure normal water supply pressure and prevent pipe bursts. The second is that the customer service center feeds back the leaks and pipe bursts reported by the m...
