摘要： 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.

摘要： An optoelectronic sensor (10) for detecting objects in a monitored zone (20) is provided which has the following: a front screen (38); a light transmitter (12) for transmitting a light beam (16); a movable deflection unit (18) for the periodic sampling of the monitored zone (20) by the light beam (16); a light receiver (26) for generating a received signal from the light beam (22) remitted by the objects; at least one test light transmitter (42); at least one test light transmitter (42), at least one test light receiver (44) and at least one test light reflector (48) which span a test light path (46a-b) through the front screen (38); and an evaluation unit (32) which is configured to acquire pieces of information on the objects in the monitored zone (20) from the received signal and to recognize an impaired light permeability of the front screen (38) from a test light signal which the test light receiver (44) generates from test light which is transmitted from the test light transmitter (42) and which is reflected at the test light reflector (48). In this respect, the test light reflector (48) is arranged such that it moves along with the deflection unit (18).
