Description

Technical Field

[0001] The utility model relates to the technical field of urban rail transit training, in particular to a five-wire switch machine turnout control training device. Background Art

[0002] As an important part of the signal system, the switch is an important guarantee for the safe and efficient operation of trains. On the one hand, the switch is responsible for important functions such as train turning back and changing lines. Once a failure occurs, it will have a significant impact on the trains on the entire line. If it cannot be restored in time, the train will be degraded or even unable to move, seriously reducing operational efficiency. Therefore, it is particularly important for signal personnel to be able to handle switch failures accurately and quickly.

[0003] However, since the switch equipment is relatively complex and the related equipment is large in size, the equipment is distributed in places such as the signal equipment room, the train control room and the track area, which is relatively scattered, expensive, noisy, and inconvenient for practical operation. Daily training mostly remains in the theoretical stage, and practical operation can only be carried out through the training base of the vehicle depot or at night maintenance points, which consumes a lot of time and energy of signal personnel, and cannot intuitively analyze and judge the fault phenomenon and circuit direction. The signal personnel training effect is not good, and the training practice is difficult. Therefore, the utility model proposes a five-wire switch control training device that integrates the switch related equipment on a display board, with a reduced equipment size but complete functions.
