摘　　要：针对校车安全问题多发现象,在分析其原因的基础上,指出了目前校车安全系统的不足,设计了一种基于物联网的校车安全报警系统。该系统主要由传感器、协调器、报警主机、声光报警、屏幕显示、控制设备、短信服务器及数据库服务器8个组成部分构成,并通过ZigBee无线传感网络进行数据采集,利用RS-232总线将数据上传报警主机处理,利用GPRS无线通信技术将数据上传数据库服务器储存及进行短信报警。通过实验测试,该系统安装维护简单、扩展性强、成本低,能为校车的安全运行提供良好的保障。According to the multiple phenomenon of school bus safety problem,based on the analysis of its causes,the paper points out the deficiency of current school bus safety system,and designs a school bus safety alarm system based on the Internet of Things.The system mainly consists of eight components,i.e.,sensors,coordinator,alarm host,sound and light alarm,screen display,control equipment,short message server and database server,and collects data through the ZigBee wireless sensor network,uploads data to alarm host by using RS-232 bus,uploads data to database server for saving and sends SMS alarm by using GPRS wireless communication technology.Through the experimental test,the system has the advantages of simple installation and maintenance,strong expansibility,low cost,can provide a good guarantee for the safety operation of the school bus.
