摘　　要：为了对农业环境进行监测和信息采集,设计一种基于LoRa无线传输的农业环境参数采集系统。该系统由监控中心和多个安置在农场不同地点的环境参数采集节点组成。农业环境参数采集节点对观测点处的环境参数和地理定位信息等数据采集;监控中心将各节点数据进行汇总,并利用LCD液晶屏和PC上位机程序进行显示和监测。该系统监控中心与各采集节点之间以星形结构组网的LoRa网络进行无线通信,有效解决传统测量方法费时费力、数据统计繁琐等问题,实现更完善的农业环境参数远程监测,提高生产效率和经济收益。In order to monitor the agricultural environment and collect its information,an agricultural environment parameter collection system based on LoRa wireless transmission is designed.The system consists of monitoring center and several environmental parameter acquisition nodes located in several points in farm.The nodes collect the environmental parameters and geographic location information at the observation point,and the data collected would be summarized by the monitoring center,which would be then displayed and monitored by LCD screen and PC upper computer program.The monitoring center of the system and the acquisition nodes are connected by the star structure Lora network for wireless communication,which effectively solves the problems of traditional measurement methods,such as time-consuming and labors,tedious data statistics and so on.The designed system realizes a better remote monitoring of agricultural environmental parameters,and improves the production efficiency and economic benefits.
