摘　　要：针对当前防盗报警装置体积大、布线复杂、及时性和准确性差的问题,提出了一种基于物联网技术的标签式防盗报警器。采用MMA7260三轴加速度传感器采集物品的加速度信息,判断其是否受力而动。利用CC2530对数据进行A/D转换和无线收发,在2.4 GHz频段信道通过ZigBee无线传感器网络传送。报警器具有可大量分布式布置的特点,能够实时、准确地监控物品的状态信息,保证被测物品的安全。For the bulk mass, wiring complex, poor timeliness and accuracy problems of current anti-theft alarm, propose a tabbed anti-theft alarm based on Internet of Things Technology. Use three-axis acceleration sensor MMA7260 collect things＇ acceleration information; determine whether it is forced moving. Use CC2530 to do A/D convert and wireless send or receive, then transmit it though ZigBee WSN at the 2.4 GHz channel. The alarm can be distributed arranged in large numbers, can monitor things＇ status information in real time and accurately, ensure things＇ security.
