摘　　要：讨论了一种新型的基于超声测距的高精度三维定位系统的原理与设计。该定位系统采用波头计数与零交叉点检测的方法来提高超声测距精度，并通过三角形方法来实现三维定位。这种三维定位系统具有精度高、成本低、易于安装、体积小、抗电磁干扰能力强、对光线不敏感、无电磁辐射等优点。The principle and design of a novel 3-D precise position- ing system based on ultrasonic distance measurement are discussed. This method enhanced the measuring accuracy by using the methods of wave head counting and zero-cross detection, and it implement- ed 3-D positioning with triangle square wave. This 3-D positioning system features high accuracy, low cost, ease installation, small dimension, high anti-EM interference capability and less sensitive to lights as well as no ray, electric and magnetic radiation.
