The invention discloses a wheel set size on-line detection method and device based on various sensors. The device comprises the first eddy current displacement sensor, the second eddy current displacement sensor and the second laser displacement sensor which are sequentially arranged on the inner side of a rail in the train heading direction, and comprises the first laser displacement sensor which is arranged on the outer side of the rail, wherein the first laser displacement sensor and the second laser displacement sensor are symmetrical about the rail. The method comprises the steps that the two laser displacement sensors detect and obtain a tread contour line, and a rim height and a rim thickness are worked out according to the geometrical relationship by extracting the tread contour line; the two eddy current displacement sensors are used for detecting the distances between the rim top point and the two eddy current displacement sensors, when the distances detected by the two eddy current displacement sensors are the same, the lowest point on the wheel rim top point circle passes through the middles of the two eddy current displacement sensors, and the wheel diameter is worked by extracting the distance readings on the eddy current displacement sensors and combining the distance readings with the rim height. According to the wheel set size on-line detection method and device, the cost is low, the principle is simple, practicability is high, and non-contact high-precision measurement is achieved.
