【摘要】：水是生命之本,是人类赖以生存必不可少的物质资源之一。可是随着工业化的高速发展、人类生活水平的提高,生产和生活排出的大量污水导致水污染越来越严重,这直接危害到了人类的健康。因此,对水质的监测显得尤为重要。但是传统的人工监测方法已经不能满足要求,因为传统的化学检测方法过程复杂而且不具有实时性,不能反应水质的最原始状态,并且这种检测方法还会带来二次污染；而现代仪器监测法是现如今水质检测的趋势,它是通过相关传感器,将被测对象的化学量或者物理量转化为电信号并经过数字化处理后输入到MCU后得到准确的参数。本文提出了一种以太阳能电池板为供电形式,STM32系列单片机为核心控制板,GPRS为数据传输平台的水质监测系统的整体设计方案。设计包括水质检测、现场LCD屏显示以及上位机软件三部分,可实时监测被测点位水质的PH、DO(溶解氧)、EC(电导率)、ORP(氧化还原点位)等参数。使用本设计的工作人员可通过现场屏幕和远程上位机软件两种方式及时的了解到水质情况并采取相应措施；也可读取系统中的SD卡得到历史数据以得到水质的变化趋势。系统每隔设定时间向传感器请求一次数据并上传,当传感器发生异常,系统会自动定位错误类型并通知服务器。随着水环境问题越来越受到重视,各级政府部门正在加大建立实时水质监测系统的力度,目前本设计己受到合肥市政府认同并以浮标的形式投放到天鹅湖试用,系统已稳定运行数月。相信,随着系统的日趋完善,本设计定会为我国水环境监测和治理做出一份贡献。
[Abstract]:Water is the basis of life and one of the essential material resources for human survival. However, with the rapid development of industrialization, the improvement of human living standards. A large amount of sewage discharged from production and living causes more and more serious water pollution, which directly endangers the health of human beings. Monitoring of water quality is particularly important, but the traditional manual monitoring method can not meet the requirements, because the traditional chemical detection process is complex and does not have real-time, can not reflect the most primitive state of water quality. And this detection method will also bring secondary pollution; And the modern instrument monitoring method is the trend of water quality detection nowadays, it is through the correlation sensor. The chemical quantity or physical quantity of the measured object is converted into electric signal, then digitally processed and input to MCU to get the accurate parameters. In this paper, a kind of solar panel is proposed as the form of power supply. The whole design scheme of water quality monitoring system with STM32 series single chip microcomputer as the core control board and data transmission platform. The design includes water quality detection. The field LCD screen display and the host computer software can monitor the water quality of the measured point in real time. ORP (redox point position) and other parameters. The staff who use this design can know the water quality situation and take the corresponding measures in time through the field screen and the remote host computer software. The SD card in the system can also be read to get the historical data to get the trend of water quality. The system requests and uploads the data to the sensor every set time, when the sensor is abnormal. The system will automatically locate the wrong type and notify the server. With the increasing attention to water environmental problems, government departments at all levels are increasing efforts to establish real-time water quality monitoring system. At present, the design has been approved by Hefei municipal government and put into use in Swan Lake in the form of buoy. The system has been running steadily for several months. I believe that with the system becoming more and more perfect. This design will make a contribution to water environment monitoring and management in China.
