The working principle is as follows: when the rubber track chassis works, firstly, under the connecting action of the connecting frame 6, the output roller 1 drives the track 2 to rotate, so that the rubber track chassis moves, at the moment, the rotation of the track 2 can drive the roller shaft 3 and the connecting roller 4 to rotate along with the roller shaft, and at the moment, the judging mechanism 5 on the connecting roller 4 can be under the action of pressure, so that the extruding block 53 drives the electric contact 54 to be extruded to the inner side of the sliding groove 51 along the inner wall of the sliding groove 51, the electric contact 54 and the conductive rail 52 are in a disconnected state, and the conductive rail 52 and the electric contact 54 in the judging mechanism 5 cannot form a complete closed ring;

when the crawler 2 is broken, the extrusion force of the crawler 2 on the extrusion block 53 disappears, at this time, under the action of the elastic force in the sliding groove 51, the electric contact 54 moves outwards along the sliding groove 51 under the action of the driving of the extrusion block 53, the electric contact 54 and the conductive rail 52 are in a closed state at the moment, and the conductive rail 52 and the electric contact 54 in the judgment mechanism 5 form a complete closed ring;
