摘要
介绍了一种以AT 89C 2051单片机为核心,利用超声波的特性设计出低成本、高精度测距仪的方法。给出了这种测距仪的硬件原理电路和主要的软件设计思路,用Psp ice对硬件的主要部分进行了模拟仿真。根据理论分析和试验统计对设计进行改进,电路达到了预期的效果。
A kind of ultrasonic telemeter based on AT89C205 is introduced. This telemeter is provided with some merits such as low cost and high-accuracy because of the ultrasonic wave characteristic. The hardware principle electric circuit and the main software design idea are showed. The simulation of the main part of the hardware has been done with Pspice. At last, according to the theoretical analysis and the experience some improvements of the design are made. The system has achieved the anticipated effect.
