Abstract: A safety system for localizing a movable machine having a safety controller, having at least one radio location system, and having at least one sensor for position determination, wherein the radio location system has radio stations arranged as stationary, wherein at least one radio transponder is arranged at the movable machine, wherein position data of the movable machine can be determined by means of the radio location system, wherein the position data can be transmitted from the radio station or from the radio transponder of the radio location system to the safety controller and position data of the movable machine can be determined by means of the sensor, and wherein the safety controller is configured to compare the position data of the radio location system and the position data of the sensor and to form checked position data on agreement.

Abstract: A safety system and a method having a safety system for localizing and identifying a person or an object, a control and evaluation unit, at least one radio location system, and having at least one identification sensor for identifying the person or the object, wherein a marking is arranged on the person or on the object, wherein the radio location system has arranged radio stations, wherein at least one radio transponder is arranged on the person or on the object, wherein position data of the person or of the object can be determined by means of the radio location system, and wherein the position data can be transmitted from the radio station of the radio location system to the control and evaluation unit, and identification data from the marking on the person or the object can be determined by means of the identification sensor.

Abstract: A safety system and a method for localizing at least one object having a control and evaluation unit have at least one radio location system. The radio location system has at least three arranged radio stations. Position data of the object can be determined by means of the radio location system and can be transmitted to the control and evaluation unit. At least three radio transponders are arranged at the object, each arranged spaced apart from one another and the three radio transponders form different points on a plane and unambiguously define the plane in space. The control and evaluation unit is configured to compare the position data of the radio transponders and to form checked position data of the object. The control and evaluation unit is configured to form orientation data of the object from the position data of the radio transponders.
