摘　　要：详细介绍了一种基于单片机实时语音播报、带有LED数码显示功能的脉冲反射式超声测距系统。利用AT89S51定时功能来计算超声波在媒质中的传播时间,进而计算出超声波在媒质中的传播距离。该仪器在工业控制、能源勘探、水利监测等领域具有广泛的应用,特别是在实时性要求比较高的领域具有更大的优势和更广阔的应用前景。This thesis introduces a kind of single-pulse reflection ultrasonic distance measurement system in detail with the functions of real-time voice broadcast and LED display based on single chip. The propagation time of ultrasonic in the medium is obtained through the timing function of AT89S51,and then the propagation distance of ultrasonic is calculated.This instrument has wide applications in the industrial control,energy exploration and water conservancy,especially in the areas of high real-time demand with greater advantages and extensive application prospects.
