一种多方位超声波测距仪的设计

由于超声波对环境的适应能力强、信息处理简单、速度快等特点而广泛应用于液位测量、机械手控制、车辆自动导航、移动机器人、物体识别等方面,但它也存在一些缺陷使得测量的准确度受到影响.基于对超声波测距原理和超声波特点的研究,针对回波信号弱,方向性差的缺陷,为了实现在某些特殊场合(如井下测量、能源勘探)的测距以及提高测量强度,提出了一种多方位超声波测距仪的设计思想.

More Than one Bearing Ultrasonic Telemeter Senor Design

As result of ultrasonic is strong to the environment acclimatization.The information processing simple.the speed is quick and so on.The ultrasonic be widely used to the fluid place measures,manipulator controls,voiture autokinetic navigation,the move robot,objoct identification and so on.But it also has some flaws to drop the accuracy of measure.Based on the measure principle of the ultrasonic and the characteristic of ultrasonic,Specifically for the echo signal is weak,directionality dispatching,in order to measure some special occasions(for example measure under the well,Energy sources prove up)and enhance the intensity.Have brought forward on kind of many bearing ultrasonic telemeter senor design.
