| 摘要: |
| 针对CAN网传输智能电子设备(IED)信息速度慢的现状,提出基于CAN网结构采用滑动窗口技术实现IED内部各通信插件之间信息交换的方法,将以太网TCP/IP协议中的"一问多答"、"断点续传"等先进技术应用到CAN网,可使IED大量的描述信息准确、快速交换,尤其是IED长时间故障录波后,可快速上传到分析终端进行故障诊断.对比试验发现,与传统的"停止一等待协议"相比,"滑动窗口协议"传输电网故障信息更加高效,同时"滑动窗口协议"配置灵活,通过改变窗口尺寸,即可兼容"停止一等待协议". |

| Abstract: |
| As the information exchange among IEDs(Intelligent Electronic Devices) on CAN(Control Area Network) is slow,the sliding window technique based on CAN structure is suggested,which adopts the advanced technique of Ethernet TCP/IP protocol,such as"multiple replies to single asking"and"continu- ous transmission after interruption".The massive descriptive information can be correctly and quickly exchanged,especially the long-time fault records can be quickly sent to analysis terminal for fault diagnosis.
