非接触式超声波角度测量方法的应用开发研究

超声波具有指向性强,遇到障碍物会被反射的特点。针对此种情况,文章利用多个超声波传感器构成传感器阵列,首先测量目标与各超声波传感器之间的距离,然后根据不同传感器与目标之间的距离差异,利用单片机解算目标的角度,最后在显示器上进行显示,从而实现了目标角度的非接触式便捷智能测量。通过实验可以看出,该角度测量器具有智能性、便携性、准确性等优点,具有一定的实用价值。

Application and Development of Methods for Contactless Ultrasonic Angle Measurement

Ultrasonic waves feature accurate directivity and will be reflected while encountering obstacles.The sensor array is constructed by using multiple ultrasonic sensors in this situation.Firstly,the distance between the target and each ultrasonic sensor is measured.And then based on the different distance between different sensors and the target,the angle of the target is calculated by the single chip microcomputer and shown on the displayer.Thereby the contactless measurement of the target angle can be achieved.It can be seen from the experiments that the angle measurer has the advantages of intelligence,portability and accuracy,which is of certain practical value.
