水质问题涉及民生，随着人们生活水平的提高，人们对水质的要求也越来越高。防范与治理水污染逐渐被人们密切关注，而水质监测终端设备也成为当下研发热点。 根据水质监测设备的要求，基于FPGA架构的DE2_115开发平台设计一种水质监测智能终端。该终端通过多参数水质传感器采集水质参数信息，通过视频传感器观察水源现场信息。采用无线网络与Web服务器进行通信，实现数据的实时传输与控制。 水质监测智能终端根据功能需求进行模块化设计，围绕开发平台DE2_115分别设计信息采集模块，存储模块，无线发送模块以及Web服务器模块。该终端以Quartus II开发软件和Nios II处理器提供的开发套件来完成各模块之间的搭建及运行。利用Niche Stack的TCP/IP Network Stack网络软件，在Micro C/OS-II上实现HTTP伺服器。通过Web服务器来远程操控采集端，实现数据的传输与接收。通过软硬件结合的方法优化各处理模块，实现监测终端的正常运行。 测试结果表明该终端运行稳定，实现了数据的采集与传输和Web服务器的远程接收与操控。为调度中心提供原水水质的动态变化信息，达到原水水质监测和预警的目的。

Water quality refer to people's livelihood, People call increasingly high requirements for water quality along with the improvement of living standards. Prevent and control water pollution is paid close attention by people gradually, and quality monitoring terminal equipment become a research hot spot. According to the requirements of water quality monitoring equipment, an intelligent terminal of water quality monitoring was designed in this paper, which was based on DE2_115 platform and FPGA architecture. This terminal got water quality parameters through multi-parameter water quality sensors, and observed environment surrounding the water source by video sensors. It uses Wireless network was used to communicate with web server to realize real-time data transmission and control. The intelligent terminal of water quality monitoring was designed according to functional requirements. The collection module, storage module, wireless transmitter module and web server module were developed around DE2_115 development platform. The terminal set up and ran between each modules by Quartus II software and NIOS II processor. HTTP sever was achieved on Micro C/OS-II via TCP/IP Network Stack network software of Niche Stack. Acquisition Side was controlled remotely through Web server and achieved in the transmission and receiving of data. Combination of hardware and software makes optimization between each processing module and ensure the monitoring terminal operated normal. Testing results show that the terminal worked stable, realized the collection and transmission of data, receiving and controlling of Web server remotely. Meanwhile, it also can provide dynamic information about raw water for dispatching centers, it got the goal of raw water quality monitoring and early-warning.
