摘要
为了提高住宅小区智能化水平,针对住宅小区所面临的盗窃、火灾及煤气泄漏等安全问题,设计基于STC89C52单片机为控制核心的小区安防系统。在进行需求分析的前提下,采用集成芯片LM393、MQ-5气体传感器、火焰传感器、DS18B20温度传感器组成检测电路,上位机实时显示监测信息。该系统可检测并显示火灾、煤气泄漏及室内盗窃等安全方面的突发事件,并具有声光报警的功能,有效地提高了小区安防的智能化水平。
In order to improve the level of intelligent district, according to the security problems of theft, fire and gas leakage in the residential district, a residential security system based on STC89G52 single chip microcomputer as the control core was designed. On the premise of the demand analysis, the system＇ s detection circuit was designed by us-ing the integrated chip LM393, MQ-5 gas sensor, flame sensor, DS18B20 temperature sensor detection circuit, and monitoring information was displayed in real time through the host computer. This system can detect and display the fire, gas leakage and indoor theft and other security emergencies, and has the function of sound and light alarm, which effectively improve the intelligent level of residential security.
