多通道超音波發射接收之偵測系統及方法

This invention provides a multi-channel ultrasonic transmitting and receiving detection system and method, which use a transmitting control system to send a plurality of detection signals, which is then sent out by a transducer. The receiving system determines a channel signal of the transmitting control system after receiving a reflection signal reflected from an obstacle so as to control a multiplexer for switching one single channel and amplifying the reflection signal. The receiving system will then perform analog-to-digital conversion, high-speed sampling and USB-high-speed transmission on the amplified reflection signal. Finally, a graphical interface of a computer performs smoothing processing on the reflection signal to present the wave form of the reflection signal for determining the distance of the obstacle.
