家居安防系统的设计

A Design of Home Security System

本文论述了家居安防系统的新需求,分析了传统安防系统存在的问题,设计了一种新型家居安防系统。系统采用网关+功能模块的结构。功能模块包括门磁传感器、红外人体探测器、烟雾探测器、可燃气体探测器,不仅实现被动入侵检测,还可实现室内火灾、可燃气体泄漏等安全主动检测。功能模块超低功耗设计,采用电池供电与ZigBee无线通信方式,安装灵活,维护便捷,满足大众家居安防需求。

In this paper, the new requirements of home security system are discussed, the problems existing in the traditional security system are analyzed, and a new home security system is designed. System adopts gateway and function module structure. The function module includes magnetic sensor, infrared human body detector, smoke detector, and gas detector. The system not only can realize the passive intrusion detection, but also realize the safe and active detection of indoor fire and combustible gas leakage. Ultra low power design is used in the function module. Function module uses the battery power supply and Zig Bee wireless communication mode. Its flexible installation and convenient maintenance can meet the needs of the public home security.
