This invention discloses a data-driven method for anomaly detection and recovery of water network sensors. It constructs minimum-order observers for sensors in the water network, solves the parameter matrix and online update rules of each minimum-order observer using historical data of the water network, and in practical use, inputs real-time input and output data of the water network into the minimum-order observers to obtain a set of real-time estimates. The absolute error of the real-time estimates is used to determine whether the sensor is abnormal. For abnormal sensors, the output data of normal sensors and real-time input data are used to reconstruct their measurement data, thus achieving anomaly recovery. Without needing to obtain a precise dynamic model of the water network and edge weight information, rapid sensor anomaly detection and data recovery can be achieved simply by constructing observers using historical input and output data, providing an efficient and robust solution for water network sensor monitoring.

The present invention relates to the field of data processing technology, and in particular to a computer data transmission system, comprising: a file initiating terminal, a preprocessing module, a first optimization module, a second optimization module, a third optimization module and a file receiving terminal; the preprocessing module evaluates the file to be transmitted, determines the transmission mode of the file to be transmitted according to the initial capacity obtained by the evaluation, and in the case where the file to be transmitted needs to be segmented, the second segmentation standard is modified by optimizing the file to be transmitted and determining the final segmentation standard, thereby obtaining a number of actual segmented files, and completing the transmission of the target content according to the requirements of the control instruction. After the file to be transmitted is segmented, the present invention realizes parallel transmission, fully utilizes the network bandwidth, speeds up the overall transmission speed, saves the transmission time, and makes it more flexible to manage the transmission process to maximize the transmission efficiency.
