Simple subway train traction braking practical training system

A simple subway train traction braking practical training system relates to a subway train practical training system and comprises a traction braking module, a data acquisition module and a computer.The traction braking module comprises a driver controller used for implementing subway train traction and braking signals, an alternating current motor used for simulating a traction motor in a subwaytrain traction system, and a frequency converter used for adjusting the rotating speed of the alternating current motor. The data acquisition module comprises a data acquisition card used for converting an operation signal of the driver controller into an analog signal and a digital signal; and the computer is used for processing the signals transmitted by the data acquisition card and outputtingdifferent frequencies to control the frequency converter. During use, the driver controller sends out a traction or braking signal, data is collected through the data collection card and transmittedto the computer, the compute
