混合运用DTMF和FSK数据通信的智能网终端实现

Realization of Mixedly Using DTMF and FSK Data Communication Intelligent Network Terminal

在介绍DTMF和FSK信号基础上,分析混合运用DTMF和FSK两种信号进行数据通信的优点,最后重点介绍一种使用该方式与智能网服务器进行数据通信的智能网终端的软硬件方案,该方案同时考虑了功耗及成本问题.

Based on introducing the two kinds of signals FSK and DTMF, the merits of mixedly using DTMF and FSK to realize data communication, are analyzed. Finally, a kind of intelligent network terminal＇s software and hardware realization are described emphatically, which uses the method to communicate with the intelligent network server. This project has also considered the power loss and the cost.
