基于无线网络的家庭安防系统的硬件设计

随着社会的进步,人们生活水平逐渐提高,对家庭财产及家居安全重视程度也不断提高。城市居民住宅小区的大量崛起,促使人们在家庭住宅的观念上逐步发生变化。人们不仅需要宽敞、豪华的住宅,同时也希望有一个安全、便利的生活空间。因此,市场上出现了很多安防产品。经过调研市场上的这些产品,发现这些产品普遍存在着智能化不足,产品功能未充分开发等问题。 本文从普通家庭的一般安全需求入手,详细说明了设计了两款系统,一款是基于无线网络的家庭安防系统,另一款是基于无线网络的控制系统。通过硬件测试,硬件系统运行正常,满足设计要求。 基于无线网络的家庭安防系统主要是针对家庭中的盗窃情况而设计的。应用成本很低的但是应用非常广泛的PT2262/PT2272组建家庭的无线传感器网络,一方面使得安装更加方便,另一方面保护了家庭内原有的装饰。用户可以设置报警电话,当有警情发生后,主机自动拨打所设置的电话,无需用户过问,提高了应急速率,可以使危害降低到最低。内置时钟芯片,为主机提供精确的时间信号,主机通过时钟芯片可以自动布防。特别是在晚上主人如果由于疏忽忘记了手动布防,主机将自动布防。 基于无线网络的控制系统,使用PT2262/PT2272组建无线传感器网络,将高端探测器和低端探测器有机的结合起来。主要针对家庭中出现的火灾,煤气泄漏,盗窃等情况,系统能够在这些情况发生的时候第一时间做出应对控制,使得损失降低到最低。系统灵活多变,充分考虑到PT2262/PT2272的资源,一个家庭中可以布防的房间数可以达到8个,探测器种类可以达到4种,每一种探测器在一个房间中的数量可以达到2个。这样可以充分满足一个家庭内的需求。探测器和主机的地址码和数据码都是可以更改的,因此,只需要遵循一定的设定规则,就可以不仅在原有系统的情况下增减探测器种类,而且可以实现同种探测器的替换。
