Abstract: A method using a safety system and a safety system for localizing at least one object, with varying locations, having at least one control and evaluation unit, and having at least one radio location system, wherein the radio location system has at least three arranged radio stations; wherein at least one radio transponder is arranged at the object; wherein position data of the radio transponder and thus position data of the object can be determined by means of the radio location system; wherein the position data can be transmitted from the radio station of the radio location system to the control and evaluation unit, wherein the control and evaluation unit is configured to cyclically detect the position data of the radio transponder and wherein a first inspection unit is provided, with the first inspection unit being connected to the control and evaluation unit, and with the control and evaluation unit being checked by the first inspection unit.

Abstract: A method for detecting an object inside a monitored zone includes monitoring at least a part of a monitored zone. Sensors generate respective single digital images of the total monitored zone, with the single images of all sensors being generated in a uniform coordinate system. Coordinate points of the single images are flagged as “safe” by each sensor if they are free of the object, with all other coordinate points being flagged as “unsafe”. The single images are each transmitted to an evaluation unit and are superimposed to form a resulting total image. The coordinate points of the total image, which are flagged as “safe”, correspond to those flagged as safe in at least one of the single images. All other coordinate points of the total image are flagged as unsafe. The coordinate points flagged as unsafe in the total image are used for the determination of the object coordinates.

Abstract: An apparatus for the control of at least one safety-relevant function of a machine is described having a machine control for the control of the movements of the machine, having at least one sensor for the sensing of an object inside a monitored zone and having an evaluation unit for the setting of a danger zone and for the triggering of the safety-relevant function on the intrusion of the sensed object into the danger zone. To set the danger zone, the evaluation unit is coupled to the machine control and the evaluation unit is designed for the derivation of the parameters required for the setting of the danger zone starting from the control signals used by the machine control for the movement control of the machine. A corresponding method is furthermore described.
