基于单片机的智能家居防火防盗系统设计

Design of Smart Home Fireproofing and Security System Based on Single-chip Microcomputer

以STC89C51单片机作为中心控制器,以烟雾传感器、红外热释电传感器和温度传感器作为信号采集模块,以LCD1602为显示模块,以ADC0832模数转换器为数据处理模块,设计了一套智能家居防火防盗系统.介绍了系统主要功能模块设计方案和功能实现过程,并对系统功能进行了验证和分析.结果表明:设计的系统可实现温度和烟雾浓度检测、人体感应监测、警戒值设置和环境数据显示等功能.

In this paper, based on the central controller of STC89C51 single-chip microcomputer, an attempt to design a smart home fireproofing and security system was presented. The system uses the smoke sensor, infrared pyroelectric sensor and temperature sensor as signal acquisition module, ADC0832 analog-to-digital converter as data processing module, and LCD1602 is regarded as display module. The design scheme and function realization process of the main functional modules of the system were introduced, and the system functions were also verified and analyzed. The results showed that the designed system can realize the functions of temperature and smoke concentration detection, human body induction, alarm value setting and environmental data presentation in the environment.
