PROBLEM TO BE SOLVED: To provide a detection method and system for operators close to the outer periphery of a heavy machine, suitable for a work side where the plurality of operators perform operation of the heavy machine and work therearound by turns.SOLUTION: Each of a plurality of operators 8a, 8b in a work side E carries an IC transmission tag 30, and a heavy machine 1 operating on the work side E is mounted with a receiver 21, an alarm 23, and a control device 10. When the heavy machine 1 is started up by any operator 8a, an operator ID of this operator is registered into the control device 10 and the alarm 23 is activated interlocking with the registration of the operator ID. When the operator ID received by the receiver 21 is different from the registered ID according to the control device 10, the alarm 23 is driven. Preferably, the control device 10 is activated interlocking with the startup of the heavy machine 1. Alarm activation means 18b may activate the alarm 23 interlocking with activation of the heavy machine engine after the registration of the operator ID, instead of interlocking with the registration of the operator ID. |
