高铁自动列车控制系统的磁暴防护探究
Research of Automatic Train Control Systems Used in High-speed Railway to Prevent Geomagnetic Storm's Infringements
摘要
Abstract
How the space radiation caused by geomagnetic storm affects FPGA devices was analyzed.This paper investigated the FPGA fault-tolerance techniques used nowadays and presented a new mitigation technique against upsets,duplication with comparison combined with time redundancy.The results show that in the minimum partitioning dual modular redundancy design,with the upset detector and voter circuit(the "DnV" circuit) no radiation-hardened,the radiation sensitive areas will be 0%.At the same time,it also overcomes the problem of excessive power consumption of the three mode redundancy.关键词
