基于高分子压电线缆的智能家居系统设计

The Design of Intelligent Home Furnishing System Based on Polymer Piezoelectric Cable

设计一套低成本、低人力、稳定可靠的家居安防系统,采用高分子压电线缆作为传感器,将压电线缆输出的电荷信号通过电荷处理电路,转换为电压脉冲信号,单片机通过AD转换,判断电压信号大小,在有人入侵时,系统完成声光报警并用步进电机旋转带动照相机拍摄入侵者照片。经过测试,系统响应速度快、定点拍摄精确高、稳定可靠、能耗低、具有很强的实用价值。

As people＇s living standards continue to improve, a low-cost, low manpower, stable and reliable home security systems are increasingly being required. This system should be adopted in accordance with the piezoelectric polymer piezoelectric material as a sensor, the charge signal output by the piezoelectric charge cable processing circuit is converted to a voltage pulse signal, the microcontroller through the AD converter to determine the voltage signal magnitude, someone invasion, sound and light alarm system complete with a stepper motor driven rotary camera intruder photos. After testing, the system response soeed, fixed-point shooting accurate, reliable, low power consumption, has a strong practical value.
