摘要
设计了一种基于ZigBee的高精度称重式雨量计。该雨量计利用称重传感器实现固态和液态降水测量,在组网情况下实现了雨量数据的实时传输。系统以STM32LI51系列ARM控制器、CC2530无线射频芯片为核心,对无线传感器网络中的终端节点、协调器节点的硬件和软件进行了设计。为了修正温度对传感器带来的输出误差,采用BP神经网络片数据进行修正和补偿。整个系统实时性好、精度高,能较好地满足现有气象观测的要求。
A high precision weighing rain gauge based on ZigBee is designed by using weighing sensor.The liquid and solid precipitation can be measured and transmitted.The gauge takes STM32L151 microprocessor and CC25300 RF chip as the core.The hardware and software of the terminal node and coordinator node are designed in wireless communication network.BP neural network is used to correct the sensor output error caused by temperature.The whole system has advantages of real-time and high accuracy,and can meet the requirements of meteorological observation.
