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 increasingly serious water pollution, water tap water to the poor quality of urban life, thus drinking water treatment and in the field of environmental protection is an important subject. In this case also begin, the design and development of some relevant quality detection instrumentation, according to some sources and learn professional knowledge, portable water quality testing for the research and design of reference and help.
First, this design using the tap water quality inspection, according to the principle and application of some easily measured variables (PH value, the concentration of oxygen, conductivity, turbidity and temperature) and single-chip microcomputer control principle and control circuit principle, the mathematical relationship between variables are easily measured by measuring the variables and mathematical calculation, so as to achieve the variables are obtained for the measuring pieces.
Secondly, the detection system hardware p
