摘要
介绍我们研制的声表面波（SAW）压力传感器频率信号检测仪。分析了8031单片机控制下的等精度测频方法的原理；介绍了仪器的硬件结构和软件设计思想，给出了硬件原理电路图和主程序的流程图。
This paper introduces a new type of frequency signal measuring set of SAW pressure sensor on which we have made research recently. The principle of equal-accuracy frequency measuring under control of 8031 single-chip micro-controller is analysed. The hardware structure and the main idea of software design are also introduced. Final1y the hardware principle circuit and the main programme flow chart are given.
