传感器在笔记本防盗器中的应用

Application of Sensors in Anti-theft Device for Notebook Computers

近年来针对笔记本等个人贵重物品被盗时有发生这一现状,设计出一种基于加速度传感器的低功耗无线防盗器。提出仅通过2个节点构建成最简单的无线传感器网络,传递PC移动信息,通知主人迅速做出反应,避免笔记本的丢失。通过硬件电路设计和软件编程烧写使整个网络得以驱动,并通过实验测验达到了预期的报警效果。解决了一般防盗器价格昂贵,系统复杂,体积较大,时延较长的缺点。

A low-power wireless anti-theft device based on acceleration sensors is designed to prevent the notebook computers and other personal valuables from being stolen from time to time.The moving message of PC is transmitted by the most simple wireless sensor networks which are built just with two nodes to notify the owner to respond quickly to avoid the loss of laptops.The whole network is driven through the hardware circuit designand software programming.The experimental testing shows that it can satisfy the alarm expected result.The shortcomings of high price,complex structure,large volume and long time delay of general anti-theft devices were overcome.The innovation point is the concept of ＂use with building＂.
