Embodiment Construction
[0054] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0055] Due to the relatively complex advantages of the external environment, sometimes miscalculation of the pull-out value occurs, and it is not possible to judge the pull-out value exceeding the limit only by the size of the pull-out value. Therefore, the present invention introduces limited conditions such as the peak-to-valley difference threshold, extreme value, and the number of contact lines, and restricts the pull-out limit judgment, reducing the problem of false alarms for pull-out value over-limit defects.
