摘要
 單片機(jī)（Micro Controller Unit 簡稱MCU）系統(tǒng)在現(xiàn)代社會(huì)的檢測和控制系統(tǒng)中得到了較為廣泛的應(yīng)用，坡度是系統(tǒng)經(jīng)常測量的量，但坡度常常是一個(gè)模擬量，而模擬量是比較難被測量出來的，因此，需要采用適當(dāng)?shù)募夹g(shù)將模擬的測量量轉(zhuǎn)化為數(shù)字測量量。在原理上雖然不是非常困難但實(shí)現(xiàn)起來，還是會(huì)遇到其它各種方面的問題。因此對(duì)單片機(jī)坡度測量系統(tǒng)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(jī)的智能坡度測量儀的設(shè)計(jì)。利用單片機(jī)對(duì)坡度等參數(shù)進(jìn)行測量，可以充分利用單片機(jī)的運(yùn)算和控制功能，方便地實(shí)現(xiàn)測量，使測量精度得到提高。同時(shí)用軟件程序代替一些硬件測量電路，可在硬件結(jié)構(gòu)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(duì)坡度參數(shù)的測量，以滿足現(xiàn)代測控系統(tǒng)的需要。

 ABSTRACT
 MCU (Micro Controller Unit) system in a modern society in the detection and control system has been more widely used, the slope system is often measured by quantity , but the slope is often an analog and analog is more difficult to be measured.therefore, requiring the use of appropriate technology  simulate the measurement into a digital measurement. Although in theory it is not very difficult to achieve, I will continue to face various other aspects.  So the slope of MCU Measurement System Research has a very important purpose and significance.
 It is mainly discussed in this paper that the design of the MCU-based Intelligent slope measuring instrument. I measure the slope and other parameters measured by the MCU,and I can take full advantage of MCU processing and control functions, to facilitate the realization of measurements for improving measurement accuracy. Simultaneously using the software procedure replaces some hardware metering circuits, and with the hardware architecture invariable situation, I can revise the software to increase the new function.  the slope parameter is well measured to achive the need in the modern observation and control system.

Key words: MCU, slope measuring circuit, figures show circuit.
