Filed: 1993-08-12
Abstract: PURPOSE:To provide an ultrasonic number-of-fish-measuring instrument which counts the number of small fishes, passing through a fish ladder by using quickly repeated pulses. CONSTITUTION:Numerous ultrasonic vibrators 3 are arranged on the bottom of a fish ladder 2 provided in a river so that small fishes can pass through the ladder 2 and high-frequency pulse signals are repeatedly inputted to the vibrators 3 from a transmission circuit 4. In addition, a receiver 5 composed of an amplifier and time gate circuit is connected to each vibrator 3 and reflected signals are inputted to the time gate circuits only when the vibrators 3 transmit ultrasonic waves and input reflected signals from the surface of the water so that the vibrators 3 can receive reflected signals from small fishes and signals from the gate circuits of the circuits 5 are fetched to a control circuit 6 and inputted to a buffer memory 7. Since small fishes swimming at high speeds are overlooked when the ultrasonic waves are transmitted at the normal frequency, the ultrasonic waves are transmitted more frequently by inputting a transmission trigger made coincident with multiple horizontal synchronizing signals against one vertical synchronizing signal by using horizontal synchronizing signals from the circuit 6 as clocks to the transmission circuit 4 and the ultrasonic waves are displayed on a display device 8. Therefore, the number of small fishes can be accurately counted from a displayed picture.
