- 目前的智能机在硬件上多采用双cpu的架构,一个是基带处理器,主要处理数字信号、语音信号的编码解码以及GSM通信协议,另一个是应用处理器,运行操作系统和各种应用程序。基带处理器、射频和其它外围芯片作为一个模块,成为GSM/GPRS modem,提供AT命令接口。网络的应用已经是一个需求的热点,而目前的GSM模块大多都能支持GPRS功能。应用处理器通过AT命令集与带GPRS功能的无线通讯模块通信,为实现网络的应用提供了一个最底层的支持。 -Intelligent machines in the
GSM
- 利用通讯模块进行数据通信,就是将数据体作为短消息的内容,从发送方的通讯模块发送出去,通过短消息中心进行转发,接收方通讯模块收到此短消息后即存储在SIM卡上,模块外接的控制器(如单片机、计算机等)从模块中读取短消息后,根据需要将无用的信息去除,取出有效信息,然后将SIM卡中的短消息删除,这样就完成一次单向数据的传输。利用通讯模块的短消息方式实现数据的发送和接收具有通信成本低、系统容量大、抗干扰能力强等优点,而且短消息经过服务中心再到达目的地的特点使通讯模块无需24小时开机,降低了系统功耗,特别适合
