1. A safety system (1) for localizing at least two objects (2) comprising:
at least one 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 two respective radio transponders (6) are arranged at the objects (2), with the two radio transponders (6) being arranged spaced apart from one another;
wherein position data of the radio transponders and thus position data of the objects (2) can be determined by means of the radio location system (4);
wherein the position data can be transmitted from the radio station (5) of the radio location system (4) to the control and evaluation unit (3);
and/or wherein the position data can be transmitted from the radio transponder (6) to the control and evaluation unit,
characterized in that
the control and evaluation unit (3) is configured to cyclically detect the position data of the radio transponders,
with the control and evaluation unit (3) being configured to cyclically compare the position data of the radio transponders (6) and to form cyclically checked position data of the objects (2).
