Transformation of Hydrology Cableway Observation System Based on EKL-3
In order to enhance the reliability of EKL-3 hydrology cableway observation system and the sampling accuracy, we transformed the inlet valve of this system, river bottom weightlessness and the data communication module, then revised the way of measuring according to the hydrology code requirement. To avoid the remaining silt to catch the valve in the sampling process we used the double barrel bistability valves; Installed a normally closed weightlessness switch on the winch lifting cable to solve the tray type river bottom weightlessness which is unable worked when it falls into sludge; we have solved the wireless signal weaken quick in the water by the double audio communication method. The test result in XIAJIANG station, WUJIANG station, the BAISHA station indicated that the reliability of the system is enhancement, the sampling precision to be able to sharpen, the transmission signal antijamming ability as well as anti-weaken ability can strengthen, and this system maintenance is convenient, especially qualify in small rivers hydrology data gathering and survey.
