摘要
GPRS传输模块的设计采用低功耗单片机MSP430F149为主控芯片,通过主控芯片发送AT指令控制内嵌TCP/IP协议的GSM/GPRS模块SIM900B来实现模块的各项功能。本文着重说明该模块在海洋水文数据传输中的应用,重点解决模块的硬件电路设计、短消息收发和GPRS网络连接等问题。
Low-power microcontroller MSP430F149 is used as the main chip in GPRS transmit module.Various functions are achieved by main chip sending AT commands to GSM/GPRS module SIM900B embedded TCP/IP protocol.This paper focuses on the application of this module in marine hydrological data wireless transmission.Some module problems are solved,such as module hardware design,receiving and sending short message and GPRS network connection.
