中文摘要：

对于工业工程中的距离与温度测量，非侵人、无干扰式测量方法日显重要。为此，利用超声波飞渡时间与相位羞两种非侵入方法，对距离与温度的同时测量进行了研究。采用单片机作为核心，结合外围电路，构建了超声波测量系统硬件，并用MonteCarlo方法对硬件系统进行了仿真与误差分析。实验结果显示，该系统的测量相对误差不超过3％，为MonteCarlo方法的工业应用奠定了基础。

英文摘要：

In distance and temperature measurement for industrial processes, the non-invasive and non-interference measuring method becomes increasingly important. Therefore, the simultaneous measurement of both distance and temperature by adopting two of the non-invasive methods, i. e. , ultrasonic flying time and phase difference methods is researched. With the single chip machine as the core, and combining with peripheral circuits, the hardware of the ultrasonic measurement system is constructed; and the simulation and error analysis for hardware are accomplished by using Monte Carlo method. The experimental results indicate the relative measurement error does not exceed 3% , this laid the foundation of industrial applications for this method.
