本科毕业设计 基于单片机的智能家居报警系统的设计 基于单片机的智能家居报警系统的设计 摘 要 随着电子技术的飞速发展，实现家居信息化已成家居系统发展的新趋势。传统的家居防盗在实际的使用中暴露了很多隐患，即使住所发生安全事故，户主也不能及时了解情况。智能家居报警系统能很好地解决这个问题。随着智能化家居概念的推广，智能家居报警系统发展迅速，它从原来的简单化、局部化向智能化、集成化发展，能对家居的安全环境进行监测，一旦发生安全事故，如火灾、被外人闯入等，就会发出报警信息，使得户主能及时对安全事故进行处理。目前市场上常见的防盗报警系统的通信方式有固定电话拨号、以太网、集群系统等。 本系统采用单片机ATMega16作为MCU，通过西门子公司的GSM模块TC35i与用户进行远程信息交换，以热释红外传感器、温度传感器DS18B20以及电子密码锁等报警信息采集模块构成安防系统，保障住户和生命财产安全。控制程序由主程序，TC35i程序、报警源信息采集程序等模块组成，其中主程序和TC35i程序共同负责短信息的发送。该系统采用现有电话网络和单片机网络控制技术，具有自动化程度高、适用性强、电路设计可靠等优点，一般家庭都能接受。 关键词：单片机 安防 GSM 短消息 the Intelligent Alarm System of Security on Single Chip Device Lin Weixing (College of Engineering, South China Agricultural University, Guangzhou 510642, China) Abstract: With the rapid development of electronic technology, realize home furnishing information has become a new trend in home furnishing system development. Home furnishing security traditional exposed a lot of problems in actual use, even if the home accidents, who can not understand the situation. Intelligent home furnishing alarm system can solve this problem well. With the development of intelligent home furnishing concept, intelligent home furnishing alarm system is developing rapidly, it is from the simple, localized to the original intelligent, integrated development, can monitor security environment of home furnishing, accidents, such as fire, by intruders, will send out alarm information, so that the time for security accident treatment. The security market common alarm system usually communicate with a fixed telephone dialing, Ethernet, cluster system. The design uses a microcontroller ATmega16 as the MCU for remote information exchange by Siemens GSM module TC35i user to constitute security systems, hydroelectric infrared sensor, temperature sensor DS18B20 and electronic lock alarm information collection module. It can protect the lives and property of residents. Control procedures by the main program, the TC35i program, alarm source information collection
