摘要
针对现有虹吸式雨量计和翻斗式雨量计的缺点,以及对现有自动气象站中雨量值实时数据采集、处理、上传困难的问题,文中提出了基于无线传感网络的压力式雨量计的设计,详细介绍了jennic5121微控制器,通过zigbee协议组建无线传感网络,对雨量值实时采集、处理、上传。文中给出系统结构,硬件电路和软件流程的设计,该压力式雨量计具有实时性好、精度高、受环境影响小的优点,能较好的满足现有气象观测的要求。
Aiming at the shortcomings of Siphon rainfall gauge and dump-type rainfall gauge, and the problems in real-time acquisition, processing and upload of the rainfall data, this paper presents a pressure pluviometer based on wireless sensor network, describes in detail the jennic5121 microcontrollers, the establishment of wireless sensor networks through Zigbee agreement, and real-time acquisition, processing, and upload process of the rainfall data. This paper also gives the system architecture, hardware circuit and software design. This pressure pluviometer is of such advantages as real-time capability, high accuracy, and less environmental effect, and fairly meets the present requirements by meteorological observation.
