摘　　要：针对野生保护动物主要分布于无信号的山区深处而难于监测的情况,提出一种利用LoRa技术的野生动物声音监测系统。文章以野生保护动物大壁虎为例,设计一种包含信息采集、LoRa网关及远程信息接收模块的声音监测系统,并对大壁虎声音进行实验分析。研究结果表明,LoRa扩频通信方式可实现在障碍物较多的山林环境下3 km范围内自行组网并准确传输数据,结合大壁虎声音特性,可准确监测其种群密度。此项研究对山区智慧农业、森林环境监测等领域具备较好参考价值。In allusion to the situation that the protected wild animals are mainly distributed in the interior of mountains without signal,and are difficult to be monitored,a wild animal sound monitoring system based on LoRa technology is proposed.Taking the big gecko,a wild protected animal,as an example,a sound monitoring system including information collection,LoRa gateway and remote information receiving modules is designed,and an experimental analysis of the gecko′s sound is performed.The research results show that the LoRa spread spectrum communication mode can realize the self networking and accurately transfer data within the scope of 3 km in the mountain environment with more obstacles,and can accurately monitor the population density of the gecko in combination with its sound characteristics.This research has a certain reference value in the fields of intelligent agriculture in mountainous areas and forest environmental monitoring.
