摘要
提出了一种通过以太网对监控分站进行固件升级的技术,该技术以Bootloader为基础,以Flash ROM为载体,实现分站固件的远程更新。论述了该技术的原理,介绍了总体方案的设计,实现的方法和具体应注意的问题。该技术通过校验机制保证数据的准确性,另一方面保证升级过程发生中断后,程序能回到旧版本的程序运行状态。通该技术稳定可靠,避免了传统固件升级方式繁琐的缺点,提高了效率。
A firmware upgrade technology for the monitoring station through the Ethernet is proposed, the technology is based on Bootloader and using Flash ROM as the carrier to implement remote firmware update. This paper expounds the principle of the technology, introduces the design of the overall scheme, the method of implementation and the specific problems needing attention.The technology ensures the accuracy of the data through the verification mechanism. On the other hand, after the interruption of the upgrade process, the program can go back to the running state of the old version of the program. The technology is stable and reliable, and avoids the complexity of traditional firmware upgrading methods and improves efficiency.
