摘要
The present invention relates to a river flow measuring system and a measuring method using the same, the river flow measuring system according to the present invention, the guide rail is installed from the rock wall to the bottom of the river, coupled to the guide rail moving pulley And, an ultrasonic flow rate distribution measuring instrument which is fixed to the moving pulley to measure the flow velocity of the corresponding depth, a flow rate data transmission device which transmits the flow rate data measured by the ultrasonic flow rate distribution measuring instrument, and controls the vertical movement distance of the moving pulley. A servo motor equipped with a line monitor, a data transmission device for converting the flow rate data transmitted from the flow rate data transmission device and the vertical movement distance data converted from the rotational speed of the servo motor into digital signals, and transmitting the ultrasonic flow rate. Inverter controlling the operation of the distribution meter and servomotor and the transmitted data Transmitter and receiver to receive and demodulate the data, and convert the flow rate to the flow rate by the programmed program by applying interpolation and precision flow calculation method using the demodulated data, storing the flow rate and flow rate data, and converting the flow rate and flow rate data into the video signal. And a microcomputer controlling the inverter.;Accordingly, it is useful for measuring the flow of rivers for grasping water resources, stream ecology, stream environment improvement, and understanding the changes and transmission characteristics of downstream streams due to multi-purpose dam discharges. In particular, it is very useful for measuring the flow rate of flat and dry season. In addition, the flow rate can be accurately calculated by continuously measuring the flow rate accurately, and there is an advantage that it is not necessary to interpolate the flow rate at the discontinuous point as in the prior art.
