Abstract

In a drinking water network, a telecontrol system must periodically acquire, store and validate sensor data to achieve accurate monitoring in real-time. Sensor data need to be validated before further use to assure the reliability of the results obtained when using them. In real operation, problems affecting the communication system, lack of reliability of sensors, or other inherent errors often arise, generating missing or false data during certain periods of time. These data must be detected and replaced by estimated data. In this paper, a methodology for data validation and reconstruction of sensor data collected from a drinking water network is developed, considering not only spatial models, but also temporal models (time-series of each sensor) and internal models of the several components in the local units (e.g., pumps, valves, flows, levels). The methodology is illustrated by means of its application to flow and level meters of the main Catalonia Regional Water Transport Networks.
