| 摘 要： | 随着对通信实时性要求的提高，特别是在传输海量数据时，传统的基于GPRS网络的数据传输单元（DTU）带宽明显不够，而基于CDMA 1X通信网络的DTU能很好的解决这一问题．以单片机为核心，结合CDMA 1X通信网络的特点，着重阐述了DTU的设计过程，给出了系统的具体实现方案，构建了它的应用系统，分析了它的硬件组成，论述了软件系统的设计流程和开发要点．

| Abstract: | Along with the increasing real-time request to the communications'efficiency,especially in the process of transmission of massive data,the bandwidth of traditional data transmit unit(DTU) based on GPRS network is obviously inadequate,however the DTU based on the CDMA 1X communication net is able to solve this problem.With micro control unit(MCU)as the core,the design course of DTU is particularly demonstrated in conjunction with characteristic of MAIZ Communication network.The concrete design scheme is given.The hardware structure is built,The design flowchart and the key design points of software system are discussed. |
