基于AVR单片机防盗报警装置的设计与实现

摘要

The alarm system is designed based on AVR microcontroller. This system consists of angular displacing detection,an anti-misinforming,and send warning message to the owner's mobile phone. By collect angle detected unit,to find the goods id taken off by others. With the help of the anti-misinforming algorithms,the system can avoid the falsity alarm because of smoothful displacement or small vibration. But the system will alarm and send warning message to the owner's mobile phone once there does exist theft. And the user can chose Bluetooth or WIFI module by personal love. This system has smaller cubage,lower power,and little fare. And it is easily fixed.%本防盗报警装置基于AVR单片机系统设计开发,由角位移检测、防误报算法、以及向手机发送警情等部分组成.通过角位移传感器检测判断物品是否发生被盗事件;在防误报算法方面考虑由于不小心的非偷盗行为产生的微小位移、抖动等现象发生时发出的错误报警,防止误报;而一旦有偷盗行为确有发生,该系统在发出蜂鸣警示的同时,可根据实际应用场景的不同,由用户自行选择蓝牙或Wi-Fi通知被偷盗人完成报警.该系统价格低廉、体积小功耗低,便于安置实施.
