江河防汛物联预警系统-硬件设计 摘 要 科技水平的发展是推动社会和人们的生活水平发展的重要力量，现在电子技术愈来愈成熟，而且人工智能也成为了时代的主流，最近还有一个大热的便是物联网，目前物联网已经成为发展的主流，物联网技术顾名思义，是需要实物还有网络通信，且现在这方面的技术也是和科技水平一样变得比以前更加成熟。江河防汛从古至今一直是人们要解决的一个重要问题。防洪防汛不仅能保证人们的生命财产安全，还可以利于水进行灌溉种植，养殖等，是人们生活中最重要的环节，也是推动社会和经济发展不可或缺的一环。本文所研究的基于物联网技术的防汛预警系统不仅可以实时监测水位还能及时得实施报警，在远程也可以对水位进行实时的监控，在后端也能及时得得知水位信息，得知是否预警，进而能够及时采取下一步措施。本文研究的江河防汛预警系统主要分为两个部分： 基于zigbeen组网的水位检测，在终端节点也就是传感器节点处zigbeen通过水位传感器器对水位进行检测，输出信号为模拟量，zigbeen通过AD转换得到输出的电压值，再根据公式计算出对应水位高度，然后通过Z-Stack协议栈将数据传输给协调器节点。 协调器节点接受各终端数据进行处理，将各节点的水位信息在OLED上显示出来，再将各子节点数据与设置的报警水位值进行对比，若超过阈值则进行预警，除此之外协调器读取GNSS定位信息再将水位数据和定位数据通过GPRS发送给远程服务器端。服务器端接受数据后，再由设计好的软件进行服务器取数，将所得到的数据显示在设计的界面上，并采用动画形式模拟水位信息。 关键词：江河防汛；物联网；zigbeen；水位检测 River Flood Control IOT Early Warning System-Hardware Design Abstract Science and technology level of development is an important factor in the development of the society and peoples living standard, now more and more mature electronic technology, and artificial intelligence became the mainstream of The Times, recently there is a big hot is the Internet of things, the Internet has become the mainstream of development, the Internet of things technology, as the name implies, is the need to physical and network communication, and now this technology is become more mature than before, science and technology level. Flood control has been an important problem to be solved since ancient times. Flood control not only ensures the safety of peoples life and property, but also facilitates irrigation, planting, farming, etc. It is the most important link in peoples life and an indispensable link in promoting social and economic development. The flood prevention and warning system based on the Internet of things technology studied in this paper can not only monitor the water level in real time but also give an alarm in time. It can also monitor the water level in real time at a remote location, and get the water level information in time at the back end, so as to know whether to give an early warning o
