摘要
單片機（Micro Controller Unit 簡稱MCU）系統在現代社會的檢測和控制系統中得到了廣泛的應用，R、L、C是系統經常需要測量的量，而模擬量是比較難被測量出來的，因此，需要采用適當的技術將模擬的測量量轉化為數字測量量。在原理上雖然不是非常困難但實現起來，還是會遇到其它各種方面的問題。因此對單片機R、L、C測量系統的研究有著非常重要的目的和意義。本文主要論述了基于單片機的智能RLC測量儀的設計，利用單片機對R、L、C等參數進行測量，可以充分利用單片機的運算和控制功能，方便地實現測量，使測量精度得到提高。同時用軟件程序代替一些硬件測量電路，可在硬件結構不變的情況下，修改軟件以增加新的功能。能夠很好的完成對RLC參數的測量，以滿足現代測控系統的需要。

ABSTRACT
MCU(Micro Controller Unit) system in a modern society detection and control system, which is widely used, R, L, C system is often measured by quantity, analog is more difficult to measure is, therefore, require the use of appropriate technology to simulate the measurement into a digital measurement. 在原理上雖然不是非常困難但實現起來，還是會遇到其它各種方面的問題。Although in theory it is not very difficult to achieve, and will continue to face various other aspects. 因此對單片機R、L、C測量系統的研究有著非常重要的目的和意義。So right MCU R, L, C Measurement System Research has a very important purpose and significance.
It is mainly discussed in this paper that the design of intellectual RLC parameter measurer based on MCU. MCU use of R, L, C, and other parameters measured, can take full advantage of MCU processing and control functions, to facilitate the realization of measurements for improved measurement accuracy. Simultaneously uses the software procedure to replace some hardware metering circuits, may in the hardware architecture invariable situation, revise software to increase the new function.Can very good completing to the RLC parameter survey, satisfy the modern observation and control system the need.
