摘要
The present disclosure relates to a method for increasing the operational safety of mobile machines (50) in aboveground or underground mining operations for the extraction of minerals by utilizing RFID technology. At least one transmitting unit (21) may be provided at the mobile machine (50). At least one receiving unit and at least one non-machine-related RFID transponder which can be activated by means of the transmitting unit and in the case of activation is contactlessly detected, may be provided. In addition, at least one reference transponder (7) and a control unit for actuating the transmitting unit and evaluating transponder signals in measuring cycles may be provided. To improve the energy requirement of the method and of a system designed therefor, the reference transponder (7) may be mounted on the mobile machine (50) at a defined distance, stored in the control unit, from the transmitting unit (21). The signal field strength L of the transmitter signal of the transmitting unit (21) may be changed in dependence on the response signal of the reference transponder (7) in a calibration cycle (KCB) for eliminating the environmental influences.
