[0002] At present, for the practical training of handling outdoor faults of railway signal equipment, generally, manually on the main signal equipment such as outdoor track circuits, switch machines, signal machines and direction boxes, a certain group of contacts are cut off. For example, insulating parts are installed on individual terminal posts, transparent tapes are used, connection wires are sealed, and temporary open circuits such as contact insulation are carried out. And after the training is completed, it needs to be restored so as not to affect the normal use in the later stage.

[0003] Since faults have a certain degree of concealment in actual situations, such temporary artificial open circuits have certain limitations on the fault points. For example, if the distance between fault points is too far, the temporary fault will be too obvious and be directly observed, thus losing the relevant significance of fault troubleshooting. In addition, this fault setting method is time-consuming and laborious, and prone to problems. For example, each time the fault is set, it is necessary to manually confirm whether the fault arrangement is correct, resulting in limited training efficiency; each time a fault is created, it will cause a certain degree of damage to the equipment; forgetting to restore the fault will not only affect the normal use of the equipment, but also affect the training effect of the next time.
