基于STC89C52的家庭智能安防系统设计

Design of Home Intelligent Security System Based on STC89C52

提高安防措施已成为现代很多家庭优先考虑的问题之一。针对家庭安全的要求,设计了一种基于单片机的家庭智能安防系统。以STC89C52单片机为主控芯片,采用GSM模块作为远程报警模块,分别采用红外对射传感器、火焰传感器、烟雾传感器,配合外围电路,组成一个多功能的安防系统。对其系统性能进行优化,实现了实时监控、现场远程报警等功能。对系统进行了测试,结果表明,系统工作稳定可靠,对居家环境能进行有效监控和报警,具有误报率低、操作简单、易于实现的优点。

With the development of today＇s society, to improve security has become one of the priority issues of the family. According to family members and property safety, a set of intelligent home security system is designed based on microcontroller. STC89C52 microcontroller is used as the main control chip, and the GSM module is used as the remote alarm module. In addition, infrared radiation sensor, flame sensor, smoke sensor, and a peripheral circuit are used to form a multifunctional security system. The system performance is optimized to realize real-time monitoring, remote alarm and other functions. It has advantages of simple operation, convenient installation, low false alarm rate and so on. Test results show that the system is stable, effective monitoring and alarm. It meets the expected design goals.
