The three trackside components of the signal system, i.e. signal, track circuit and turnout, are the basic equipment for ensuring the normal running of trains and are the key content of rail transit teaching. Turnout is the weak link of train lines, and turnout failure will directly affect the safe and orderly running of trains. Therefore, in the process of rail transit teaching, it is important to train students to quickly and accurately troubleshoot turnout failures.

[0029] In the embodiment of the utility model, as Figure 1 shown, the switch machine simulation device includes PLC controller and relay device, and the PLC controller is connected with the relay device in control. The relay device includes four relays, that is, KA1 relay, KA2 relay, KA3 relay and KA4 relay, and the PLC controller is connected with the KA1 relay, KA2 relay, KA3 relay and KA4 relay in control.
