便携式数据传送终端设计

Design of a Portable Data Transmission Terminal

根据基层机动单位传送数据信息的需求,针对文本、图片、数据信息的传送问题,研制了便携式数据传送终端,开发了其配套服务器软件。围绕终端系统功能,提出了硬件实现方案及软件功能模块,采用主控制模块、调制解调器模块、逻辑控制模块、U盘控制模块等完成硬件设计;文件系统的单片机移植和数据加密解密等为设计的关键技术。样机开通运行后,各项功能正常,其技术指标达到预期的目标。实际应用表明,该终端方便了基层机动单位的文件收集、分发及管理。

According to the demand and the problems of data transmission,a portable data transmission ter鄄minal is designed,alone with its server software. The hardware realization and software function modules aredescribed,including the main control module,the modem module,logic control module,and U disc controlmodule. The key technology concerns single chip micyoco of the data system and data encryption/ decryp-tion. Functions of the sample terminal are normal and specfications meet the desired goal. Application of theterminal proves that it makes data collection,transmission and arrangement convenient for basic units.
