| 摘 要： | 介绍基于LPC2378开发的配变监测终端程序远程更新方法,利用芯片自带的IAP功能实现片内Flash上的程序更新,从而避免了使用对硬件配置要求较高的商业嵌入式操作系统。同时,将LZW压缩算法应用到程序更新中,使程序更新文件压缩了40%,大大缩减了通信流量,节省了终端的存储空间。

| Abstract: | A program remote updating method of distribution transformer monitoring terminal based on LPC2378 is introduced.The method updates the program in Flash with built-in IAP function of LPC2378 instead of commercial embedded operating system which demands better hardware.LZW compression algorithm is used in the updating,compressing the size of the program updating file by 40% and reducing the communication flows and the required storage space of the terminal. |
