【摘要】：近年来,水质安全成了社会关注的焦点。国内水质污染问题日益加重,而目前国内市场上缺乏一种集多参数水质快速检测与快速水域环境分析于一体的解决方案,对此,项目组决定开发一套由数据采集终端、网络服务器、控制中心及用户APP组成的“互联网+移动式水环境现场监测系统”平台。手持式水质测试仪为数据采集终端的一种,具备水质测试、数据上传等功能,同时也具备友好的用户界面和简洁性的操作方式。本文围绕手持式水质测试仪的设计与实现展开研究,核心内容为手持式水质测试仪的硬件电路的设计与实现、嵌入式软件的设计与实现及整机测试。完成的主要工作有:1.硬件电路方面,本文着重实现了电路系统中主要的电子器件的选型及模块电路的设计。模块电路包括电源模块、控制器模块、显示模块、颜色传感器模块、存储器模块、联网模块、定位模块及若干接口电路等。2.嵌入式软件方面,作者首先实现UCOSIII实时操作系统、emWin图形库及FATFS在控制器上的移植,然后完成存储、联网、定位、测频等功能,最后完成水质测试算法及校正算法的设计与实现。3.整机测试方面,本文对仪器的运行、存储、网络、定位、水质测量精度及调试接口进行测试,被测试的每项功能都能达到较为理想的效果。本仪器已经投放到市场,并赢得了广大用户的接受和认可,也得到一些来自用户的反馈,为本仪器的进一步改进提供了方向。
[Abstract]:In recent years, water quality safety has become the focus of attention of the society. The domestic water pollution problem is becoming more and more serious. However, there is a lack of a solution that integrates multi-parameter water quality rapid detection and rapid water environment analysis in the domestic market. The project team decided to develop a "mobile water environment monitoring system on the Internet" consisting of a data acquisition terminal, a network server, a control center and a user APP. The hand-held water quality tester is a kind of data acquisition terminal. It has the functions of water quality testing, data uploading and so on. At the same time, it also has friendly user interface and simple operation mode. This paper focuses on the design and implementation of hand-held water quality tester. The core contents are the design and realization of hardware circuit of hand-held water quality tester, the design and realization of embedded software and the testing of the whole machine. This paper focuses on the selection of the main electronic devices and the design of the module circuit in the circuit system. The module circuit includes power supply module, controller module, display module, color sensor module, memory module, networking module. In the aspect of embedded software, the author realizes the transplantation of UCOSIII real-time operating system UCOSIII graphics library and FATFS on the controller, and then completes the functions of storage, networking, positioning, frequency measurement and so on. Finally, the design and implementation of water quality testing algorithm and correction algorithm are completed .3. in the whole machine test, this paper tests the operation, storage, network, positioning, water quality measurement precision and debugging interface of the instrument. The instrument has been put into the market and won the acceptance and approval of the majority of users, as well as some feedback from the users, which provides a direction for further improvement of the instrument.
