基于AT89S52的GSM安防系统

本人最近弄了个基于AT89S52的GSM安防系统，想到当初由一个新手开始做这个的时候在找案例参考基本都看不懂。所以我做好这个项目后，就把它无私贡献给大家。希望对有兴趣的朋友有所帮助。这是一整套的成品，里面有说明文档，99SE的原理图和PCB，还有全套代码。在这里需要说明一点的是，由于本人孤军做此项目，所以很多地方都不是很完善。

该程序已经实现发生警报，然后通过GSM发送短信到目标号码，然后由目标再回发相应的控制短信去控制。

I recently broke a AT89S52 of GSM based security systems, originally thought of starting from a novice to do this when looking for the basic reference case are read. So I do this project, put it selflessly to the party. Want to help friends who are interested. This is a set of finished product, which has documentation, 99SE schematic and PCB, have a complete code. Need to point out here is that, because I alone in doing this project, many places are not quite perfect.

The program has been achieved alarm occurred, and then send text messages to the destination GSM number, and then issued by the goal of returning to the corresponding control messages to control.
