DISCONNECTION DETECTION SENSOR AND TRANSMISSION METHOD FOR CRACK PROGRESS SITUATION

摘要

PROBLEM TO BE SOLVED: To provide a technique for observing a crack generated on material, construction, machinery or the like.SOLUTION: A disconnection detection sensor arranges, at an intervals of crack measurement resolution, a plurality of liner disconnection detection elements which is electrically broken when tensile force exceeds a threshold value. The disconnection detection sensor connects RFIDs respectively each having different individual identification information to each of the plurality of liner disconnection detection elements. Using electromotive force which is generated by radio wave received by respective RFID as electric power source, the disconnection detection sensor transmits via information which represents existence of disconnection on a disconnection detection element connected to the disconnection detection sensor while associating with own individual identification information.SELECTED DRAWING: Figure 2
