基于特征字符串的GSM短信模块接口设计

Design of GSM SMS Module Interface Based on Feature String

短信接口程序是解决移动技术在企业网络中应用问题的有效途径,它能够把方便快捷的短信技术与企业各应用系统无缝对接;为实现计算机对短信的自动收/发,对基于GSM的短信接口进行了设计,分析了计算机利用GSM短信模块收发短信的工作原理,根据短信模块响应AT命令所返回的字符串,提出了一种基于"特征字符串"来控制接收/发送动作的设计方案,并在Windows XP平台下用Delphi 7.0加以实现;测试结果表明,该设计方案具有较高的发送速率和接收响应速度。

For the seamless SMS technology application on the enterprise application systems, SMS interface is the efficient method for the mobile technology application on the enterprise network. In order＇to realize automatic sending/receiving between computer and SMS Module, the SMS interface based GSM is designed, the mechanism for sending/receiving SMS with PC and GSM SMS Module is analyzed. Because the GSM SMS Module will return corresponding strings to PC for receiving different AT Commands, a design to control the receiving/sending of GSM SMS based on the feature strings is presented. The design with Borland Delphi 7.0 is implemented based on the Windows XP platform. The test results indicate that the design can send and receive SMS at higher speed.
