基于手机短信服务的网上选课系统设计

为使选课系统更加灵活、便于使用,提出了基于手机短信服务的选课方式,对采用这种方式的选课系统进行了功能规划和软硬件设计.这种选课系统应可以通过Web浏览器和手机收发短信进行选课、查询,并具有监控、报表功能.硬件设计着重介绍了利用单片机、M22手机模块和串口扩展芯片GM8125搭建的嵌入式短消息处理器.软件设计着重介绍了基于AT指令和C51语言的手机模块控制程序.这种选课方式作为网上选课方式的补充,受到的限制更少,因而具有较好的应有前景.

Design of elective system based on GSM short message service

To make the elective system more flexible and handy,an elective manner based on short message service is put forward.It's function is preplanned as well as the hardware and software of this system are designed.This system is used through web explore and mobile telephone short message to select course and inquiry.It also has the function of monitor and report.Hardware desiring emphasized how to construct an embedded short message server used single chip computer,M22 module,and serial port extend chip GM8125.Sof- tware designing emphasized mobile telephone model controlling program based on AT(attention)command system and C51 language. An elective system based on short message service as a makeup of net elective system has less limit,so it will widely be used.
