The national railway signal simulation training system is mainly used to train students of national railway signal and electrical personnel of railway bureau. According to the composition of the signal equipment and the curriculum of the signal profession in institutions, the system is composed of signal basic equipment experimental system, station interlocking experimental system, inter-district blocking experimental system, high speed rail train control experimental system, etc. The system emphasizes the cross-fertilization of various aspects of knowledge and knowledge and knowledge and ability to achieve comprehensive and innovative capabilities. The system builds a national railway signal simulation training base identical to the real field environment through actual signal basic equipment (relay, signal machine, rutting machine, track circuit, etc.) + 1:1 full-featured software and hardware simulation of national railway signal control equipment (computer interlocking, column control center, wireless blocking center, CTC/TDCS, etc.) + full range of training and teaching services (circuit fault setting, hardware board fault setting, automatic issuance and execution of training tasks, automatic assessment and analysis, etc.).
