基于ZigBee的幼儿园无线指纹识别接送系统设计

Design of ZigBee-based wireless fingerprint recognition picking-up and dropping-off system of kindergarten

针对幼儿园在儿童接送管理方面存在的冒领、错接、拐骗和绑架等安全问题,设计了一种基于ZigBee的幼儿园无线指纹识别接送系统。系统分别获取接送人员和儿童的指纹与事先录入指纹库中的指纹模板进行比对,如果匹配成功,则将匹配信息通过ZigBee无线网络上传给服务器,同时通过GSM短消息提醒模块通知儿童的家长;而对于那些企图进行冒领的不法分子,节点会发出报警信息,提醒门卫立即采取措施。另外,还设计了可移动的巡逻节点,以保证幼儿园环境的安全。该系统结合ZigBee技术和指纹识别技术,能有效地解决幼儿园在儿童接送管理方面存在的问题,给儿童的安全提供了一种有力的保护措施。

In view of the safety issues existing in children′s picking-up and dropping-off management of kindergartens,such as impersonator,picking up kids by mistake,kidnapping and abduction,a ZigBee-based wireless fingerprint recognition system for picking up and dropping off children of kindergarten were designed. It acquires the surrogate′s and children′s fingerprints,and then compares them with fingerprint templates in the fingerprint database that have been gathered before. If the matching is successful,it will transfer the matching information to the coordinator through the ZigBee wireless network,and inform the children′s parents simultaneously by means of the GSM short message reminder module. The node will send out an alarm to remind the guard to take an immediate measure when the criminals attempt to impersonate one kid. In addition,a patrolling node is designed to ensure the safety of kindergarten environment. In combination with the ZigBee technology and the fingerprint recognition technology,the system can solve the above problems effectively and provide a powerful protective measure for the children going to kindergarten.
