摘要 针对幼儿被遗忘校车惨遭闷死的事件,基于ZigBee技术研制了一种校车防滞留检测报警系统。系统通过ZigBee无线传感器网络中的声音传感器和人体红外传感器同时检测幼儿滞留情况,并上传数据到控制中心判断是否存在异常,如果存在异常则控制报警系统给出声光报警提示,并通过GSM模块发送报警短信到指定号码。设计充分发挥了ZigBee无线传感器网络低功耗、低成本、分布式和自组织的4大优点。通过软硬件设计实现了系统的功能,实验测试结果表明,系统检测异常情况的成功率高,响应时间短,能够为幼儿的生命安全起到保驾护航的作用。 Aiming at the death of detained children in school bus,a detection and alarm system based on ZigBee technology is developed.The system detects the children′s detention through the sound sensor and infrared sensor in ZigBee wireless sensor network,and uploads the data to the control center to judge if there is any abnormality.If there is an abnormality,the control alarm system gives the sound and light alarm prompt,and sends the alarm short message to the designated number through GSM module.The design gives full play to the four advantages of ZigBee wireless sensor network:low power consumption,low cost,distributed and self-organizing.The function of the system is realized by software and hardware design.The experimental results show that the system has high success rate and short response time in detecting abnormal situations.It can play an escort role for the safety of children′s lives.
