Abstract: A method and a safety system for localizing at least two objects has a control and evaluation unit, and at least one radio location system. The radio location system has at least three arranged radio stations, wherein at least two respective radio transponders are arranged at the objects. The two radio transponders are arranged spaced apart from one another. Position data of the radio transponders and thus position data of the objects can be determined by means of the radio location system, and the position data can be transmitted from the radio station of the radio location system to the control and evaluation unit and/or the position data can be transmitted from the radio transponder to the control and evaluation unit. The control and evaluation unit is configured to cyclically detect and compare the position data of the radio transponders.

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 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 and a safety system for localizing at least two objects with varying locations, having at least one control and evaluation unit, having at least one radio location system, wherein the radio location system has at least three arranged radio stations, wherein at least one respective radio transponder is arranged at the objects, wherein first objects are persons and second objects are mobile objects, wherein the radio transponders have identification, wherein a respective radio transponder is at least associated with either a respective person or a mobile object, whereby the control and evaluation unit is configured to distinguish the persons and mobile objects, and wherein the control and evaluation unit is configured to associate a risk classification with each person at least in dependence on the position of the person with respect to at least one mobile object.
