For the driving simulation, the most important information is the position information of the section signal and the station boundary marked by the incoming and outgoing signal (for displaying the station and its affiliated station tracks and switches). With this information, we can in fact use the dynamic modeling to automatically place the block signal in the right place, display the station and its affiliated tracks, switches and station affiliated buildings.
The position information of the interval signal machine is a numerical value which can be read at any time in the driving simulation process. The LKJ screen displays the relative distance of the front traffic signal and the attribute of the front traffic signal (whether the traffic signal passes through or enters or leaves the station traffic signal). When software is actually operated, the accurate matching of the 3D view and the position information of the annunciator in the simulation unit can be realized. When the actual parking space of the locomotive needs to be trained and the position of the signal machine has deviation (advance or lag), the model can modify the position of the signal machine in front at any time, and the situation can be simulated vividly.
