基于单片机的水质监测系统的设计作 者薛松林指导老师张仲义摘要:现在水源污染已经成了社会密切关注的话题，所以对水质进行监测成了保护水资源的一项重要措施，基于此本文设计了一款能够有效监测水质的系统。对于水质的监测主要是监测水中自由离子浓度和水的浑浊度。设计的方案是基于单 AT89C51 单片机，对水源进行采集，再通过传感器对采集到的水源进行处理产生模拟信号，之后再通过模拟信号转变成数字信号转换器（A/D 转换器），转变之后的信号传送给单片机，单片机接收到信号之后进行处理后再显示模块进行显示。通过本设计可以有效地得出水中浑浊度、自由离子浓度，从而推断水的污染情况！在本设计中，系统地介绍了水质监测的原理、硬件的结构、工作原理及其使用和各部分功能电路的设计。关键词:水质监测、AT89C51 单片机、数据采集、A/D 转换、水中自由离子浓度、浑浊度、传感器Water quality monitoring system based on single chip design abstract: now water pollution has become a social topic closely, so the water quality monitoring has become an important measures to protect water, I designed a model based on effective monitoring of water quality system. Monitoring for water quality monitoring is mainly free ion concentration in water and the turbidity of water. Design scheme is based on single AT89C51, the acquisition of water and water supply were collected by sensors to produce analog signal processing, and then through the analog signal into digital signal converter (A/D converter), after the change of signal is transmitted to MCU, MCU receives the signal after processed before display module display. Through this design can effectively draw the water turbidity, free ion concentration, to judge the water pollution situation! In this design, systematically introduces the principle of water quality monitoring, the hardware structure, working principle and its usage and function circuit design of each partKeywords: water quality monitoring, AT89C51 single c...
