Device and method for detecting longitudinal tear in conveyor belt

A device for detecting a longitudinal tear in a conveyor belt, the device comprising:

• an embedded body embedded in the conveyor belt;
• a detector configured to wirelessly communicate with the embedded body without contacting the conveyor belt;
• and
• a calculation unit connected to the detector;
• the embedded body comprising an integrated circuit (IC) tag that is passive and a detection element connected to the IC tag, extending in a width direction of the conveyor belt outside the IC tag to form a loop circuit, and having a linear shape,
• in the calculation unit, at least position data in a longitudinal direction in the conveyor belt is stored in association with tag unique information for specifying the IC tag as embedded position data of the IC tag in the conveyor belt and further, at least position data in the longitudinal direction in the conveyor belt is stored in association with element identification information for specifying detection element as position information for the IC tag to which the detection element forming the loop circuit is connected,
• the detector being configured to emit a transmission radio wave toward the IC tag, and the calculation unit is configured to determine presence or absence of energization of the loop circuit by using information transmitted from the IC tag to the detector via a return radio wave emitted from the IC tag in response to the transmission radio wave, and in accordance with this determination result, presence or absence of generation of a longitudinal tear in the conveyor belt in a range where the loop circuit is embedded being detected, and
• the tag unique information of the IC tag connected to the loop circuit being healthy and the element identification information of the detection element forming the loop circuit are transmitted via the return radio wave and received by the detector.
