摘　　要：为了优化校车室内传感器和控制器的布局,消除现有的安全隐患,提出了基于Zigbee技术的校车安全监控系统。Zigbee模块构建星型通讯网络,中心节点汇集传感器节点的实时信息并广播控制指令给控制节点;STM32单片机处理实时信息,控制整个系统运行。最终增强了酒驾监控、学生人数检测的性能,有效地提高了校车的安全性。For optimizing the layout of sensors and controllers in school buses,and removing hidden dangers,a monitoring system for school bus safety based on the Zigbee technology is presented in this paper. The communication network is built by Zigbee module. The center node collects real-time information offered by sensors in data collection nodes,and broadcasts instructions to the control nodes. STM32 single chip controls the entire system by processing the real-time information and making decisions. The control for drunk driving and the performance of calculating the number of students are enhanced,which effectively improves the security of school buses.
