摘要
本文提出了一种基于单片机信号处理的分布式防盗报警系统的软硬件设计方法,该系统包含有线式探测头和无线式探测头,探测头可以是基于热释电的主动式红外传感器或者是基于多普勒频移原理的微波雷达传感器。该系统具有检测范围大、组网方便灵活、灵敏度可调等优点,通过对软件算法的优化,使得系统具有较高的可靠性,且误报率低。
The paper has put forward a kind of software and hardware design method of distributed burglar alarm system based on signal processing technology of SCM. This system includes wired type detecting head and wireless type detecting head, which are the active pyroelectric infrared sensor or microwave radar sensor based on the Doppler principle of frequency moved. The system has many advantages ,such as big testing ranges, convenient and flexible of group＇s network and adjustable of the sensitivity. By using the optimization of the software algorithm, the system has higher dependabilit; and lower rate of false alarm.
