【摘要】 鉴于智能终端的系统软件远程升级和维护困难的问题,提出了一种基于LPC2114和GPRS的远程系统软件升级的设计方案。介绍了LPC2114的主要性能和特点,片上Flash的构成及IAP编程原理,GPRS数据传输的通信协议,并系统地阐述了IAP技术在远程配变监控终端上的应用与实现。实践证明该方案较好地解决了终端软件远程升级和维护困难的问题,缩短了终端软件系统的开发周期。最后对远程IAP升级方案的可靠性进行了探讨。更多还原

【Abstract】 Directing the difficulty of remote maintenance and updating of the intelligent terminal’s software system,a design for remote software system updating based on LPC2114 and GPRS is presented.It introduces the performance,characteristic of LPC2114,the on-chip flash memory configuration and IAP programming principle,the communication protocol of data transportation in GPRS,then systemically expandes the remote IAP application in the monitoring of power distribution terminal.Practice has proved that the approach has solved the difficulty of remote maintenance and updating of the terminal’s software system,it also helps to shorten the development period of terminal’s software system.The thesis discusses its reliability at last.更多还原
