摘　　要：针对特种纤维检测控制系统各节点软件升级困难的问题,设计了基于CAN总线应用层协议的一种远程在线升级系统,实现了单节点、多节点同时在线升级。通过实际运行分析,该系统具有可靠性高、升级操作简便、系统稳定的特点,对一般工业网络中的节点升级具有参考意义。Aiming at the nodes software upgrading difficulty of special fiber detection and control system,a remote online upgrade system based on CAN bus application layer protocol is designed. The single node upgrade mode and multi-nodes upgrade mode are achieved. Ex- perimental results indicate that the system is high reliable,convenient to operate and stable,and the system has reference significance for the node upgrading in general industrial network.
