超声测距是一种生物仿真测距技术,它利用超声波在空气中传播速度为一恒定值,测量超声波从甲地传播到乙地所需时间从而得知甲乙两地间的距离,实现非接触测量。它以独特的测量方式广泛应用于建筑、农业、水利、地矿、交通等测量中。过去超声测距仪一直是从国外进口,在此之前国内尚未生产出此类产品。 Ultrasound distance measurement is a kind of biological simulation distance measurement technology, which uses the ultrasonic propagation velocity in the air as a constant value, the ultrasonic wave propagation from A to B to the time required to know the distance between A and B, to achieve non-contact measuring. It is a unique measurement widely used in construction, agriculture, water conservancy, mining, transportation and other measurements. In the past ultrasonic range finder has been imported from abroad, before this has not been produced in China.
