PROBLEM TO BE SOLVED: To provide an approach detection system capable of changing a level of a warning according to the distance between a worker and an apparatus, and setting the distance of issuing the warning on an apparatus side.SOLUTION: The approach detection system comprises: an RFID tag with an induction field detection function, to be attached to a worker; and a distance detection control device to be attached to a mobile apparatus. The RFID tag with the induction field detection function can set multiple magnetic field detection sensitivity and has means for intermittently transmitting magnetic field detection sensitivity setting data and magnetic field detection data, to the distance detection control device. The distance detection control device outputs different warning levels depending on received data. |
