Abstract
A crack detection system and an apparatus equipped with a crack detection circuit, including a main body, and a detection control circuit and a detection coil disposed on the main body. The main body includes a top surface, a bottom surface, and a side surface coupled between the top surface and the bottom surface. The detection coil is distributed on an edge of the main body and disposed surrounding the side surface. Two ends of the detection coil are electrically coupled to the detection control circuit to form a closed-loop detection circuit. The detection circuit is configured to detect a crack in an edge region of the main body. The detection coil includes a plurality of detection sections sequentially coupled from head-to-tail, and adjacent detection sections are not collinear.
