Speed sensor performance test practical training device

A speed sensor performance test practical training device relates to a practical training system and comprises a driver controller used for implementing train traction and braking. The data acquisition card A is used for converting signals of the driver controller into analog and digital signals and transmitting the analog and digital signals to the computer; the alternating-current motor is usedfor simulating a traction motor; the frequency converter is used for adjusting the rotating speed of the alternating-current motor; the encoder is used for acquiring the standard running speed of thealternating current motor; the speed sensor is used for measuring the actual running speed of the alternating-current motor; the data acquisition card B is used for collecting the standard operation speed and the actual operation speed of the alternating current motor and transmitting the standard operation speed and the actual operation speed to the computer for processing; the computer is used for processing the data inf
