摘要
伴随着自动化技术的快速发展,在核电领域,国产安全级分布式控制系统(DCS)技术发展迅猛.安全级显示单元SVDU是核电厂安全级DCS的一个重要组成部分,其主要功能是向操作员提供接收到的与安全相关的参数信息,同时支持操作员通过SVDU向相关的安全系统发送必要的控制指令.文中设计了SVDU安全通信机制算法,在此基础上提出一种SVDU冗余通信的方案,既保证了安全级DCS平台安全通信的一致性,又有效地提高了SVDU通信的可靠性.
With the rapid development of automation technology,in the field of nuclear power,domestic security level DCS technology develops rapidly.SVDU is the abbreviation of safety level display unit,and is an important part of safety grade DCS of nuclear power plant.Its main function is to provide operators with information about safety parameters received,at the same time,it supports operators to send necessary control commands to related safety systems through SVDU.This paper designs a SVDU safety communication mechanism algorithm,it ensures the consistency of safety communication on security level DCS platform,and effectively improves the reliability of SVDU communication.
