具有语音功能的超声波测距仪

Speech FunctionUltrasonic Distance Detector

介绍一种基于单片机AT89C52的超声波测距系统,它带有ISD2590语音芯片,能实时读出所测距离,采用一线串行温度传感器DS18B20修正声波传播速度。并介绍了该系统的硬件电路及软件设计,实验表明该系统测量精度高,抗干扰能力强,并具有微型化数字显示和语音播报等功能。

An ultrasonic distance detector, based on a single-chip computer AT 89C52 with a speech chip ISD2590 is introduced. It can read out distance measurement in real time. A serial 1 - wire temperature sensors DS18B20 is adopted to regulate the speed of sound wave. The hardware electric circuit and software design of the system are described. The experiment express that this system are highaccuracy, super anti - jamming capacity, and it also has mi- cro digital display and the speech function.
