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.

Abstract: A method is provided using a safety system. The safety system has an electronic access system for a safety zone for objects, at least one radio transponder and at least one radio station to recognize the radio transponder, at least one control and evaluation unit that is connected to the radio station for evaluating the read radio transponder information, and at least one spatially bounded access zone having an access station. The safety zone is only accessible via the access zone so that the access zone can be passed through by the object before reaching the safety zone and after leaving the safety zone, with the access station being actuated when an object passes through the access zone. Permitted objects have the radio transponder, with the radio transponder having an identification whereby the object can be identified. The permitted objects having the radio transponder can pass through the access zone.

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 provi
