基于压力传感器的笔记本电脑防盗报警装置

Burglar Alarm Device for Notebook Computer Based on Press Sensor

针对笔记本电脑安全防盗问题,设计了一种采用压力传感器的笔记本电脑防盗报警装置.通过压力传感器感知笔记本电脑对散热架的压力产生的形变,转化为相应的电信号,然后经过信号处理,实现笔记本电脑的防盗功能.该报警装置结构简单、成本低廉,具有较高的实用价值,适合于产业化生产.

Considering the problem of the anti-burglar alarm of the notebook computer, a burglar alarm device for notebook computer based on press sensor was designed. The pressure sensor was used for the deformation sensing caused by the pressure of the notebook computer on the heat dissipation plane. Then the anti-burglar function of the notebook computer was carried out by pro- cessing the electronic signal converted by the sensor signal. It has the characteristics of the simple structure, low cost and high prac- tical value. Furthermore, it suits for the industrialization production.
