        In the present invention, in the case of a flood light in which the flow rate is rapidly increased in a river, a pair of laser beam transmitters and receivers are installed upstream and downstream, respectively, at regular intervals at both points of the bank embankment, and then the laser beam reflector attachment buoy dropped in the center of the river is installed. When the laser beam is passed between the laser beam transmitter and the receiver installed upstream of the stream, the laser beam emitted from the laser beam launcher is reflected by the laser reflector so that the reflected laser beam is received by the laser beam receiver. When the laser beam reflector attachment buoy passes a distance between the laser beam transmitter and receiver installed downstream from a certain installation section, the laser beam emitted from the laser beam launcher causes the laser reflector of the laser beam reflector attachment buoy to reflect the laser beam. The laser beam receiver to receive the received laser beam The low beam reflector attachment buoy transmits measured data such as the time it takes to move between the laser beam launcher and receiver installed at a certain distance upstream and downstream of the stream to a computer and uses the flow measurement program previously inputted to the computer to It is a flow rate estimation method using a flow rate estimator that can automatically measure the flow rate of rivers flooded by measuring the average velocity of the sections.

        An object of the present invention is to remotely calculate the flow rate using a device that automatically calculates the flow rate of the river by measuring the average flow rate of the stream automatically 24 hours in a bad weather such as flood by using the above method To provide a way.

        Conventionally, as shown in FIG. 1, a person directly measures a rich man's time flowing down a certain section of a river at a constant measuring position of the river to measure the flow velocity of the river. If the conditions are bad or at night, it is very difficult to measure the dwell time of the rich man has been raised as a disadvantage that can not measure the exact flow rate.

        In addition, as shown in FIG. 2, the ultrasonic launch device is installed at a predetermined position upstream of the stream, and the ultrasonic receiver is installed at a position opposite to the point where the ultrasonic emitting device is installed at a predetermined distance away from the downstream. When the ultrasonic wave is received by the ultrasonic receiver after passing a certain point upstream or downstream on the ride, the received time is measured to indirectly measure the flow velocity of the stream and calculate the flow rate of the stream using the flow rate.

        In the above method, during the flooding period when the water floods the river, the ultrasonic wave is emitted to the stream, so that the flow of the water is very difficult to pass through the fluid. Due to a variety of materials, such as to provide a very unfavorable condition for the ultrasonic passage through the fluid, it is difficult to effectively measure the flow rate, which is a disadvantage in that the acidity of the flow rate is inaccurate.

        The present invention has been proposed to improve the above problems, and installed a pair of laser beam transmitters and receivers upstream and downstream, respectively, at regular intervals on both sides of the river banks, and then attached to the laser beam reflector dropped in the center of the river. When the buoy passes between the laser beam transmitter and the receiver installed upstream of the river, the laser beam emitted from the laser beam launcher is reflected by the laser reflector so that the reflected laser beam is received by the laser beam receiver. When the laser beam reflector attachment buoy passes through the laser beam transmitter and receiver installed downstream at a certain distance, the laser beam emitted from the laser beam launcher causes the laser reflector of the laser beam reflector attachment buoy to reflect the laser beam. The laser beam receiver receives the received laser beam The laser beam reflector attachment buoy is transmitted to the computer by measuring the time it takes to move between the laser beam launcher and receiver installed at a certain distance upstream and downstream of the stream. It measures the flow rate of the river where flood is generated by measuring the average flow rate of a certain section, and provides a method to calculate the flow rate by using a device that can measure the flow rate remotely 24 hours regardless of weather conditions. It is.

        According to the present invention, a pair of laser beam transmitters and receivers 40 and 42 are installed at both sides of the levees 10 in the flooded rivers 11 at regular intervals, and at the center of the rivers 11. When the dropped laser beam reflector attachment buoy 30 passes between the laser beam transmitter and receivers 40 and 42 installed upstream of the river 11, the laser beam 45 emitted from the laser beam launcher 40 is lasered. After the laser beam 45 is reflected by the reflector 31 so that the reflected laser beam 45 is received by the laser beam receiver 42, the laser beam reflector attachment buoy 30 is separated from the predetermined installation section. When passing between the laser beam transmitter and the receivers 40 and 42 installed downstream, the laser beam 45 emitted from the laser beam launcher 40 causes the laser reflector 31 of the laser beam reflector attachment buoy 30 to be laser beamed. Reflects the reflected laser beam 45 to a laser beam Data for measuring the time taken for the laser beam reflector attachment buoy 30 to move between the laser beam launcher and the receivers 40 and 42 installed at a predetermined interval up and down the stream 11 by allowing the new device 42 to receive it. To measure the average flow rate of a certain section of the river 11 by using a flow rate measurement program pre-input to the computer 44 to the computer 44, the flow rate to automatically measure the flow rate of the river flows the flood It is characterized by a method of estimating the flow rate using an estimator.

Transmitting data measured in the time required to move between the laser beam launcher and the receivers 40 and 42 apart from the predetermined installation section 41 upstream and downstream of the river 11 to the computer 44 and inputting the data to the computer in advance.
