Research on digital twin system for railway station signals

Railway signal is the technical assembly to ensure the safety of railway traffic, how to intuitively observe the operation of railway signal equipment is crucial, two-dimensional state of the computer interlocking system obviously can no longer meet the current needs of the times, digital twin as a new technology, can be observed from a dynamic multi-dimensional, multi-scale perspective of the physical world, cognitive, this paper will be based on the computer interlocking system, through the digital twin. This paper will establish a station digital twin software based on the computer chain system, based on the establishment of this system, it can monitor the railway signal in real time intuitively; this system can show the working process and working principle of the station signal equipment in detail, and achieve the effect of three station redisplay, so it also has a positive effect on the training of station staff and students studying railway signal system.
