摘要
核电仪控系统关系国家的核电安全,采用国产芯片实现仪控系统至关重要,只有基于国产技术平台才能从内在保障核级仪控系统的安全。基于国产芯片实现仪控系统过程中,面临系统设计、器件选型,以及新的系统架构下如何满足产品的稳定性、可靠性、独立性和确定性等问题,给出了基于国产芯片、计算机技术平台的核级仪控系统主控板卡的设计与实现,并重点对独立性和确定性设计进行了说明。对主控板卡的性能指标进行了测量,结果表明使用国产芯片实现的控制系统满足关键指标要求,主控板卡的设计与实现对核电仪控系统国产化具有参考意义。
The nuclear power instrument and control(I&C)system is related to the country′s nuclear power safety.It is very important to use domestic chips to realize the I&C system.Only based on the domestic technology platform can guarantee the safety of the nuclear-level I&C system internally.In the process of implementing the instrument and control system based on domestic chips,we are faced with the problems of system design,device selection,and how to meet the stability,reliability,independence and certainty of products under the new system architecture.This paper presents the design and implementation of the control principle of the nuclear-level instrument and control system based on domestic chips and computer technology platform,and focuses on the independent and deterministic design.In this paper,the performance indicators of the main control unit are measured.The results show that the control system realized by using domestic chips meets the requirements of key indicators.The design and implementation of the main control unit has reference significance for the localization of nuclear power I&C systems.
