The invention provides a stored and calibrated wheel diameter value validity verification method, which specifically comprises the following steps of: in the running process of a train, carrying out first-time wheel diameter calibration based on a wheel diameter calibration beacon, updating a wheel diameter calibration state according to a first-time wheel diameter calibration result, storing a calibrated wheel diameter value, and calculating the calibration precision of the first-time wheel diameter calibration; detecting the reading condition of the wheel diameter calibration beacon in real time, performing secondary wheel diameter calibration based on the wheel diameter calibration beacon when the wheel diameter calibration beacon is read again, and calculating the calibration precision of the secondary wheel diameter calibration; and comparing the calibration precision of the first-time wheel diameter calibration with the calibration precision of the second-time wheel diameter calibration, verifying the validity of the stored wheel diameter value according to a comparison result, and updating the stored wheel diameter value according to a validity verification result. According to the method, the wheel diameter value can be updated according to the calibration precision of the stored wheel diameter value and the re-calibrated wheel diameter value, it is ensured that the stored wheel diameter value is the wheel diameter value with the highest precision, and high-precision positioning of a train is guaranteed.
