Distance measurement method and device using ultrasonic waves

使用超声波的距离测量方法与装置

Abstract

The present invention provides a distance measurement method and device using ultrasonic waves. The present invention includes sufficiently amplifying a received ultrasonic wave signal and separating a specific frequency from an ultrasonic wave signal mixed with an unnecessary signal to extract an arrival signal of a first pulse. It is thus possible to calculate a distance of an object safely.
本发明提供了一种使用超声波的距离测量方法与装置。本发明涉及到充分放大接收到的超声波信号,并且从混有多余信号的超声波信号中将特定的频率分离出来,以提取第一个脉冲的到达信号。因此可以精确地计算目标的距离。
