However, because the thickness of the steel plate is different and the distance from the length measuring wheel to the steel plate is also different, a fixed limit baffle for measuring the position of the length measuring wheel cannot be installed, and an interlocking signal for starting the length measuring wheel to work cannot be effectively transmitted; especially, when a plurality of length measuring wheels are needed to carry out joint measurement, intermediate gear-breaking is easy to generate, and the measured data is inaccurate. For example, in an automatic flaw detector, the normal map is shown in fig. 2, but when the second length measuring wheel is lifted to finish the work, the third length measuring wheel does not fall down within a specified time due to the blockage of the cylinder and the like, so that a neutral position occurs between the second length measuring wheel and the third length measuring wheel length measuring encoder, and the map of the flaw detector is easy to be misplaced, as shown in fig. 3, two parts originally having the same straight line in the middle are present, so that a flaw judgment error and a flaw judgment omission are caused.
