摘　　要：在大型智能系统中,种类繁多的嵌入各种控制软件的设备分布于不同的使用环境中,如何运用系统既有的现场总线来解决嵌入式设备程序的维护问题,是提高工作效率的关键所在。文中介绍了一种基于CAN总线实现远程在线更新程序的技术。运用TI公司提供的Flash API函数库,用编程的方式来实现对TMS320F2808片内Flash存储资源的读写操作,再借助上位机辅助软件来实现远程在线更新。侧重介绍几种不同编程方式的选择原则、实现原理以及过程中需要注意的问题。这种方式在实际工程运用中得到了验证,工作稳定可靠。In the large-scale intelligent system, many embedded equipments are distributed in different environments. A key problem is how to enhance work efficiency, and how to solve the problem of online remote updating program technology based on field bus. This paper introduces a custom programming implementation of using CAN bus communication to upgrade the program in the TMS320F2808 on-chip Flash together with using Flash API lib of TI offering, with emphasis on the selection principle of different hardware program- ming modes. A brief summary of their functional operation, the principle of the remote updating online and the problem that you must take extra care are presented. This method works stablely work. program with during actual work.
