摘要
短信息业务是移动网络上的一种基本无线业务,系统以数据终端为核心,将现场采集的数据以短信息的方式发送到监控中心,从而实现了无线数据传输。对无线数据传输系统的构成进行了研究,阐述了基于C8051F020微处理器和CDMA模块MG801A的数据终端的硬件设计电路和软件接口的实现。本设计的数据终端简单、经济、实用,在工程领域以及工业控制中具有一定的实用性和参考价值。
Short message service is a basic wireless service of mobile network. The system on the basis of DTU, sends the collected data by short message to supervision center, so the system can carry out wireless data transmission. The paper introduces structure of wireless data transmission system, and expounds realization of hardware design circuit and software of DTU based on C8051F020 microprocessor and CDMA module MG801A. The system designed is simple and applicable, which offers a good reference for engineering applications and industry control.
