摘　　要：该文基于物联网设计一种自动气象信息采集系统,可以实时获取气象信息,保证终端显示结果与真实情况具有一致性。该文首先介绍自动气象信息采集系统的整体设计思路,以及智能传感器节点及其硬件电路和软件程序的设计要点;随后对比了常规Leach算法和改进Leach算法在传感网节能方面的优劣势,并设计仿真试验验证2种算法的节能效果。仿真结果表明,相比于常规Leach算法,使用改进Leach算法的传感网,在无数据融合时数据采集总量可提升11.35%;有数据融合时,数据采集总量可提升30.27%。由此可见,使用改进Leach算法的自动气象信息采集系统在运行时能耗更低,节能效果更好。This paper designs an automatic meteorological information acquisition system based on the Internet of Things,which can obtain real-time meteorological information and ensure that the terminal display results are consistent with the real situation.This paper first introduces the overall design idea of the automatic meteorological information acquisition system,and the key points of the design of the intelligent sensor node and its hardware circuit and software program,then compares the advantages and disadvantages of the conventional Leach algorithm and the improved Leach algorithm in the sensor network energy saving,and finally designs a simulation experiment to verify the energy saving effect of the two algorithms.The simulation results show that,compared with the conventional Leach algorithm,the sensor network using the improved Leach algorithm can increase the total amount of data collection by 11.35%without data fusion and 30.27%with data fusion.Thus,it can be seen that the automatic meteorological information collection system using the improved Leach algorithm has lower energy consumption and better energy-saving effect.
