文档介绍：基于CDMA数据传输终端的设计与实现
摘要
本课题研究内容为利用一个低功耗的单片机MSP430来设计一个数据传送终端。它以短消息作为数据传输的载体,将现场采集的数据通过中国联通的CDMA网络传送给监控中心,供相应的在监控中心进行数据处理、存储,并提查询、统计及报表功能。也可将监控中心的指令发送给终端设备。
本论文首先对MCU430控制CDMA模块的技术进行了介绍,研究了模块收发短信的基本原理。重点对系统终端中采用的串行通信技术做了详细的分析与描述。文章还介绍了
SMS短消息原理及协议,实现短信收发相关的AT指令集。
该装置简单,成本低体积小,功能多,易于集成设计,,实用性强等特点,它可以作为其它控制系统的平台,也可以单独的运行,有着广阔的应用。
关键词: MSP430 FD5105A AT指令集
Based on CDMA data transmission terminal design and realization
Abstract
This paper introduce designs a data transfer terminal using a 16 bits MCU MSP430. It use SMS as data transmission the carrier, transmits the scene gathering data through China 's work send to the monitoring center, carries on the data processing, the memory in the monitoring center, and provides the corresponding inquiry, the statistics and the report form function.
This system used the MCU MSP430F149 to control a cdma module FD5105A to realize SMS receiving and transmitering, Firstly, the article introduced the CDMA MODULE location technique, which used in vehicle location and navigation system, studies the basic theory of module vehicle location. The dissertation made detailed analysis and description to the munication technology that is adopted in the terminal system especially, including receiving and sending etc.
This equipment is smart and cost a little , it was used wildly ,It may take other control systems the platform, Also may the independent movement, have the broad application.
