基于SIM900A的智能家居远程防盗报警系统的设计
[摘要] 近些年来我国人民的生活水平一直在不断的提高，家庭的安全防盗方面也越来越受到人们的重视，而随着移动网络技术以及智能家居方面的快速发展，智能家居远程防盗报警系统也走进了寻常百姓家。本文主要设计和介绍了一种使用AT89S52单片机进行控制，通过SIM900A模块进行通信的防盗报警控制系统。本系统可以实现当主人外出时对家庭房间内部空间进行检测有没有人非法进入的功能，当探测到有人进入的时候，报警系统可以现场发出警报的声音，可以对私自进入的人施加心理压力，与此同时，单片机控制SIM900A模块给预先设定好的手机号码发送报警信息；如果进入的人是家里主人的认识的人，那么也可以使用系统设定好的那个手机号码对报警系统发送短消息进行远程关闭报警系统。本系统硬件方面主要分为SIM900A模块电路、红外探测模块电路、现场报警模块电路和单片机外围电路；系统的软件方面使用了能被所有手机兼容的基于AT指令中的PDU模式编写程序。

Smart home based on SIM900A remote anti-theft alarm system design
[Abstract] In recent years our country people’s living standard has been constantly improved, the safety of the family security is more and more get people’s attention, and with the mobile network technology and the rapid development of smart home, intelligent household remote anti-theft alarm system also entered the ordinary people. This article mainly introduced how to use a design and AT89S52 single chip microcomputer to control, through SIM900A modules communicate anti-theft alarm control system. This system can be achieved when the master to go out to test the family room interior space if anyone illegally entering the function, when detect someone entering the sound of the alarm system can alert the scene, can apply for to enter the mental pressure, at the same time, single chip microcomputer control SIM900A module to the predefined phone number send alarm information; If people enter the home owner is the person who is know, so you can also use the system set the cell phone number to send short message alarm system remotely close alarm system. The system hardware is mainly divided into SIM900A module circuit, infrared detection module circuit, alarm module circuit and MCU peripheral circuit; System software USES the all mobile compatible can be based on the AT command in the PDU mode to write programs.
