[0031] With reference to Figure 1 and Figure 2 , the present disclosure provides an electric control simulation teaching board for a crossing protection device, the electric control simulation teaching board for a crossing protection device comprising:

[0032] a workbench 1 having a circular track 3, a crossing 4, and a protection device 2, the crossing 4 penetrating at least one of the circular track 3, the protection device 2 being arranged on both sides of the crossing 4, the protection device 2 comprising proximity sensors 21, a protection signal machine 23, a barrier monitoring limiter 24, a barrier machine 25, a crossing signal machine 26, a warning indicator 27, and an arrival sensor 22 arranged on both sides of the crossing 4 and spaced apart;
