Method for detecting conversion force of actuating rod of three-phase alternating current point switch

The invention relates to a three-phase alternating current point switch actuating rod conversion force detection method, which is characterized by comprising a three-phase alternating current asynchronous motor (1), a speed reduction and motion conversion assembly (2), a point switch actuating rod (3), a rotating speed or rotating angle detection device (4), a sensor (5), a processing unit (6) and mode selection hardware (7), a driving output shaft of the three-phase alternating-current asynchronous motor (1) is in shaft connection with the speed reduction and motion change assembly (2); the three-phase alternating current asynchronous motor (1) drives the speed reduction and motion change assembly (2). According to the method for detecting the switching force of the actuating rod of the three-phase alternating current switch machine, the switching force on the actuating rod of the switch machine can be continuously measured and calculated in real time in the switching process of the switch machine, maintenan
