Remote Water Level Measurement System Based on Ultrasonic Ranging and Wireless Data Transmission Technology
Flow released by hydropower station in daily regulation mode results in rapid water level change in downstream waterway, and thus brings the safety problems of shipping. This paper presents a remote water level measurement system, which meets the need of real-time water level monitoring and early-warning for shipping based on ultrasonic ranging and wireless data transmission technology. The ultrasonic water level gauge is used to measure the water level in waterway, eliminating the problems associated with the manual water level gauge and measuring well, and proven to be more suitable for field water level monitoring. Through the wireless data transmission module via GPRS/CDMA network, the measured water level data can be transmitted to data center timely and accurately. The water level database is used to store and manage the real-time water level data, and provides the basis for further applications. The water level data can be queried and analyzed for a variety of applications in the system, and information of the waterway can be accessed via the network. This paper also describes the automatic early-warning function of the measurement system. Once meeting the early-warning criteria of the waterway, an early-warning message of water level will be automatically sent to the certain persons in the waterway management department, which provides decision support for shipping scheduling. The system with real time water level monitoring and earlywarning function provides powerful information support for shipping scheduling and management, and has been applied in the real-time water level monitoring project in the waterway of Lancang River. The system has shown a good prospect in a wide range of applications.
