摘　　要：介绍了基于单片机C8051F410的温室WSN节点的恶劣环境测试平台的系统构建,系统的软硬件设计以及上位机控制及通讯界面的设计。介绍了C8051F410和节点MSP430F135通讯的建立,测试系统的组成及工作原理以及应用该测试平台来测试WSN节点的工作原理和工作流程。并给出了数据采集程序流程、上位机控制算法流程的框图。测试平台采用模糊自整定PID控制方式,具有同时控制平台温度和湿度的功能,能够实时采集数据,处理、显示数据和控制功能。文中还给出了无线传感网络节点的构成及工作原理和流程,讨论了温湿度对节点功耗、传输距离、丢包率等关键指标的影响。最后给出了测试平台的WSN节点恶劣环境测试算法。The temperature and humidity in a greenhouse is very important for WSN node performance. In order to research temperature and humidity on the performance of WSN, a greenhouse WSN harsh environment testing platform based on C8051F410 was introduced, included the system＇s hardware, software design and PC control communications interface design. The test system composition and work principle, the principle of testing the WSN performance and the workflow on this platform were expatiated. The process of data collection procedures, PC control algorithm were given. The system adopts fuzzy self-tuning PID control arithmetic which has auto-measurement, gathering and dealing with real-time data and show control result, etc. The composition, work principles and processes of the wireless sensor network nodes in greenhouse were description. The impact to node of key indicators such as power, transmission distance, packet loss rate on temperature and humidity were discussed. The performance testing algo-rithm were presented.
