Δx=x1+x2+x3-1435-2×δ (2)
wherein 1435 shows that the gauge of the standard rail is 1435 mm, delta is the distance between the inner side surface of the rail head of the steel rail and the inner side surface of the rail web, and the delta values of the steel rails with different types are different.
6. The on-line gauge measuring system according to claim 3 or 4, wherein: the method for identifying the steel rail and the light spot by the second control circuit board comprises the following steps: the method comprises the steps of firstly carrying out graying processing on an acquired image to obtain a grayscale image, then carrying out filtering and denoising processing on the acquired image by utilizing a wavelet transform filtering algorithm, and then separating a steel rail image from a complex background by a two-dimensional maximum entropy threshold segmentation method.
7. The gauge on-line measuring system of claim 1, wherein: the scheme for realizing the on-line track gauge monitoring comprises the following steps: initializing a system, transmitting acquired information to a second control circuit board by a laser ranging sensor, calculating a current track gauge value by the second control circuit board, acquiring image information of a steel rail by a high-definition camera, and transmitting the acquired image to the second control circuit board for image recognition processing, wherein the laser ranging sensor actively transmits a laser beam to a rail web of the steel rail during measurement to form a light spot on the rail web, recognizing the light spot image information from the steel rail image after recognizing the steel rail information, judging whether the light spot information on the rail web is recognized once the steel rail information is recognized, judging that the current calculated track gauge value is an effective value by the second control circuit board after recognizing the light spot image information, and transmitting the current calculated track gauge value to the first control circuit board; when the laser beam sent by the laser ranging sensor is shielded by other sundries, the laser beam cannot irradiate the rail web of the steel rail, light spots on the rail web cannot be identified on the steel rail picture collected by the camera, the second control circuit board judges that the track gauge value collected by the current laser ranging sensor is invalid and does not send out the track gauge measured value, the second control circuit board sends the first control circuit board that the track gauge at the position has false detection, and the first control circuit board controls the 5G module to send a signal for maintenance to workers in relevant departments of the railway.
