摘 要
我国水环境污染日趋严重，水源水质变差导致自来水质量的不断下滑，因此城市生活饮用水和自来水处理一直是环境保护领域的一个重要的课题。在这种情况下我国也开始重视起来，也设计和研制了一些有关水质检测的仪器仪表，本文根据一些原始资料和所学的专业知识，为便携式自来水水质检测仪的研究与设计提供借鉴和帮助。
首先，本设计利用自来水水质检测的原理和应用，根据一些易测变量（PH值、溶解氧浓度、电导率、浊度、温度）和单片机控制原理以及测控电路原理等难测变量之间的数学关系，通过测量易测变量和数学计算得到难测变量，从而实现对难测变量的测量。
其次，本检测系统硬件部分是以AT89S52单片机为核心的扩展电路，包括A/D转换、电源电路、外部时钟电路、数据采集电路、LCD显示电路、键盘显示电路以及复位电路等组成。软件部分是在Windows集成开发环境uVision5l下，采用单片机高级语言C5l编写完成。最后，总结了此检测系统的未来发展前景。

Abstract
China's worsening water pollution, water quality deterioration resulting in declining water quality, so drinking water and water of urban life to deal with the field of environmental protection has always been an important issue. In this case also began to pay attention to our country, but also the design and development of a number of water quality testing instruments and meters, according to some raw data in this article and the study of expertise, water quality for portable detector designed to provide the research and learn from and help .
First, the design of the use of tap water quality testing and application of the principle, according to some easily measured variable (PH value, dissolved oxygen concentration, conductivity, turbidity, temperature) and the principle of single-chip control circuit, as well as monitoring and control variables, such as unpredictable The mathematical relationship between the easily measured by measuring the variables and mathematical calculations to be variable and unpredictable in order to achieve the measurement of unpredictable variables.
Secondly, the detection system hardware is based on single chip AT89S52 expansion as the core circuit, including the A / D converter, power supply circuit, the external clock circuit, data acquisition circuit, LCD display circuit, keyboard, display circuit and reset circuit and so on. Software in Windows integrated development environment uVision5l, the use of single-chip high-level language C5l prepared. In conclusion, summed up the future of this detection system development.
