Wireless Real-time Observation System for Water Level of Urban Drainage

摘要

Real-time water level observation in urban drainageis essential 'o control rainwater or sewage storage so as toreduce overflow pollution. To achieve real-time data accessing,wireless communication and ultrasonic Water level gauge areintegrated to design the observation system. A developedwireless real-time observation system for Caohejing drainagesysem in Shanghai, with the area of 3.74 km~2, is presened toshow how to control storm drainage so as to reduce dry-weather pump discharging, which also displays reliability ofthe system.
