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: 变压器防盗报警器源码、原理图和PCB(protel 2004).MCU是STC89C58RD+.变压器防盗报警装置是针对野外的基站低压变压器被盗现象严重而开发的一种智能防盗报警系统。该装置采用RS422/ RS485通信手段，传输稳定可靠，维护方便等特点。弥补了传统集群式系统功耗高，通信距离短，购买价格昂贵等缺点。该产品采用高集成度的单片机作为控制核心，具有功能强，体积小，运行可靠等特点。-Transformer burglar alarm.Sound code, schematic diagram and PCB.MCU:STC89C58RD+.The transformer burglar alarm is aims at the open country the base depot low pressure transformer to rob one kind of intelligence security alarm system which the phenomenon serious develops. This equipment uses RS422/stably the RS485 means of communication, the transmission reliable, maintains characteristics and so on convenience. Made up the traditional colony type system power loss to be high, the signal distance was short, purchase price expensive and so on shortcomings. This product uses the high integration rate the monolithic integrated circuit to take the control core, has function, the volume is small, movement reliable and so on characteristics. Platform: |
