1、第I页辽宁科技大学本科生毕业设计(论文)物品移动短信报警系统设计摘要贵重物品的小型化趋势,使这些物品的体积越来越小。不幸的是,便携性带来的另一个问题就是物品很容易被盗。传统的防盗方法主要是机械式的防盗锁,这种防盗锁很笨重,而且要把设备拆卸下来也很麻烦,因此影响到了物品的便携性。所以嵌入防盗系统成为我们的主要研究方向。本系统采用了由华为生产的GTM900-C模块,借用无线发送和接收、基带处理等功能,来实现无线数据传输和短信收发任务。系统中采用的振动加速度传感器具有制作简单、成本低、安装方便、防盗性能稳定等特点,采用外部供电方式
2、,它的信号易于处理并经单片机系统处理后方便和PC机通信。可实现报警信号的无线快速传递,同时能直接将报警信息传送到客户手机终端上,方便及时报警,通过GPRS模块也能使该系统与PC终端相连,方便多系统的协调统一管理。GTM900-C借用无线发送和接收、基带处理等功能,来实现无线数据传输和短信收发任务。结合AT89C51单片机,外加串口电路,报警电路以及显示模块,设计了防盗检测并报警的硬件系统和软件系统。关键词:GTM900-C;报警器;振动传感器;单片机第II页辽宁科技大学本科生毕业设计(论文)AbstractGnarlwire
