DEVELOPMENT OF HYDROLOGICAL CABLEWAY SAND CONTROL MEASUREMENT INSTRUMENT BASED ON THE DOUBLE AUDIO FREQUENCY SIGNAL CONTROL
摘要
Abstract
According to the automatic cable measurement instruments widely used in hydrologic station, which has some problems such as cannot measurement and sampling sediment normally, we carried out the development of hydrological cableway sand control measurement instrument. The automatic control instrument will organically combine double tube double steady water sample collected valves and lead fish, reasonable decorate into the drainage pipeline and communication lines, the horizontal and vertical of hydrological cableway operate accurate positions, with double audio signal to transmit reliable control subsea sampler valve switch, acquisition section of each location, different depth of water samples, and send back the valve switch status signal in time. Practice has proved that the adoption of double tube double steady water samples collected valves can solve the problem of inlet pipe alluvial sediment under closed pressure, at the same time valve no need to seal. It also implements the hydrological monitoring data two-way transmission control of the bank to the water and the water to the shore.关键词
