本论文通过分析智能居家安全领域在国内外的发展现状以及结合国内居民实际生

This paper analyzes the development status of the smart home security field at home and abroad and combines with the actual lifestyle of domestic residents to design a smart home security system with perfect functions and superior performance. The STC89C51 microcontroller, three sensors, LCD1602 liquid crystal, buzzer and led lamp local alarm circuit and GSM mobile communication and other circuit designs are introduced in detail; then based on the software program development, the signal collection and analysis, status display, abnormal alarm, etc. are effectively completed The functional programming and the use of Proteus8 software for simulation and debugging, and finally to simulate and monitor the indoor security status through physical objects.

This paper designs a smart home security system with perfect function and superior performance by analyzing the development status of the field of intelligent home security at home and abroad and combining the actual life style of domestic residents. The design of STC89C51 microcontroller, three sensors, LCD1602 LCD, buzzer and led lamp local alarm circuit and GSM mobile communication circuit design, and then based on software program development, the program design and utilization of signal acquisition and analysis, status display, abnormal alarm and other functions are effectively completed, and Proteus8 software is simulated and debugged, and finally the physical simulation and monitoring of indoor safety status.

In this paper, by analyzing the development of intelligent home security field at home and abroad, and combining with the actual life style of domestic residents, we design an intelligent home security system with perfect function and superior performance. This paper introduces the circuit design of STC89C51 single chip microcomputer, three kinds of sensors, LCD1602 liquid crystal, buzzer, LED lamp local alarm circuit and GSM mobile communication. Then based on the software development, the program design of signal acquisition and analysis, status display, abnormal alarm and other functions is completed effectively, and the simulation debugging is carried out by using proteus8 software. Finally, the indoor monitoring is simulated by the real object Security status.
