摘要
设计了一种基于ARM7内核aduc7024为主控芯片的IAP技术在监控分站远程升级程序中的应用方案,分别从IAP原理、Bootloader设计与二级中断映射原理等方向进行详细设计;与此同时,为了监控分站远程升级程序过程的安全性以及纠错能力,在软件上设计了掉电数据保护与误码容错,从而保证监控分站程序的远程在线更新的稳定性与正确性。
This paper designs an application scheme of IAP technology based on ARM7 core aduc7024 as the main control chip in the monitoring sub-station remote upgrade program,from IAP principle,Bootloader design and detailed design of the secondary interrupt mapping principle.At the same time,in order to monitor the safety and error correction capability of the remote upgrade procedure of the substation,the power failure data protection and error tolerance are designed by the software to ensure the stability and correctness of the remote online update of the monitoring substation program.
