Description: 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。
更多请查看附件里面的说明文档-AT89S52 based on the GSM security system
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.

Description: GSM/gps通信程序：双串口控制。当时我编这程序时还是花了不少力气的。
(1)gsm部分：以AT指令控制西门子TC35模块。程序代码精简。也可以用于TC35i，MC45,TC45的控制.
(2)采用GPS标准协议格式，获取GPS模块发来的时间、位置、速度等信息。该程序经过试验验证.
程序中，实现GPS信息的接收，并和其它信息一起编码成GSM传输协议格式发送出去。-GSM/gps Communication Program: Two serial control. When I compile this program, or spent a lot of effort for. (1) gsm Part: AT command to control the Siemens TC35 module. Streamlined code. Can also be used TC35i, MC45, TC45 control. (2) The standard protocol format, GPS, GPS module made to obtain the time, location, speed and other information. After the test verification process. Program to achieve GPS information received, and other information with the coded format of GSM protocol to send out.
