| 中文摘要: |
| 以核电站数字仪控系统为背景,以提高网络通信可靠性为目的,提出一种基于DeviceNet现场总线协议的安全通信层协议设计.本研究通过分析国标IEC61784所提出的八种通信故障,在原协议的基础上扩展了几种安全措施,可以预防以上所有通信故障,保证整个通信系统的可靠性和安全性.本文在硬件平台MICON系统上进行了协议栈的开发和验证,实验证明这些措施能够满足该平台对可靠性及安全性的需求. |

| For the purpose of improving the reliability of the network communication in the digital instrumentation and control system of nuclear power plant,a safety communication protocol design based on DeviceNet was proposed.According to the eight kinds of communication failures defined in the national standard IEC61784,we extended several safety measures to prevent those communication failures and ensure the reliability and safety of the whole communication system.In order to verify their validity,we developed a protocol stack on the MICON platform and designed some test cases.The test results show that they can meet the needs of reliability and safety for the platform. |
