The Development and Application of Small Watershed Hydrological Telemetry System

Abstract:

Small watershed floods have a short confluence time. Aiming at the demand of flash floods forecast, we do this research mainly around two key components, telemetry terminal and central station software. First, we design the telemetry terminal technology index, telemetry terminal circuit and GXU-1001 Hydrological Telemetry Terminal. They all based on equipment interface, communication channel, working mode, data sampling, solid-state storage, data query, parameter settings, power management, equipment, power consumption and other special technical requirements. Second, we developed central station software for GXU-1001, realize the telemetry terminal set parameters, received and compiled data, managed database, remote diagnosis and calibration, forwarded data, leak proof message, etc. The application in medium reservoirs of Baise, Guangxi, China shows the water level, rainfall, and images can be automatically acquired, transfered and processed. It provides timely and accurate hydrological data for the flood control and disaster mitigation.
