Abstract: A safety system (1) and a method using a safety system (1) for localizing at least one spatially variable object (2) having at least one first real time control and evaluation unit (3), having at least one radio location system (4), wherein the radio location system (4 has at least three arranged radio stations (5); wherein at least one radio transponder (6) is arranged at the object (2); wherein the radio transponder (6) has a check unit (8); wherein the radio transponder (6) has safe switch outputs (9); wherein position data of the radio transponder and thus position data of the object (2) are determined by means of the radio location system (4); wherein the position data are transmitted to the first real time control and evaluation unit (3) by the radio stations (5) of the radio location system (4); wherein the first real time control and evaluation unit (3) is configured to cyclically detect the position data of the radio transponder (6); wherein a second real time control and evaluation unit (7) is provided; wherein the second real time control and evaluation unit (7) is connected to the first real time control and evaluation unit (3); wherein the first real time control and evaluation unit (3) is checked by the second real time control and evaluation unit (7); wherein the second real time control and evaluation unit (7) is configured with two channels; and wherein there is a radio communication connection between the radio transponder and the second real time control and evaluation unit (7) via the first real time control and evaluation unit (3).

Abstract: A method using a safety system for localizing a person and/or object in a monitored zone having a control and evaluation unit, having at least one radio location system for the position determination of the person and/or object in the monitored zone, wherein the control and evaluation unit is configured to evaluate position data of the radio location system and status information of a spatially resolving sensor and, if a person and/or object is/are determined in the monitored zone by the radio location system, the control and evaluation unit is configured to set the spatially resolving sensor into operation at a non-reduced safety level and, if no person and/or no object is/are determined in the monitored zone by the radio location system, the control and evaluation unit is configured to set the spatially resolving sensor into operation at a reduced safety level.
