Safety system and method using a safety system

A safety system for localizing at least one object with varying locations, the safety system having at least one control and evaluation unit, and at least one radio location system,

• wherein the at least one radio location system has at least three arranged radio stations;
• wherein at least one radio transponder is arranged at the at least one object;
• wherein position data of the at least one radio transponder and the object is determined by the at least one radio location system;
• wherein the position data is transmitted from the at least three radio stations of the at least one radio location system to the at least one control and evaluation unit;
• wherein the control and evaluation unit is configured to cyclically detect the position data of the at least one radio transponder;
• wherein the safety system further comprises a first inspection unit connected to the control and evaluation unit, the control and evaluation unit being monitored by the first inspection unit, and
• wherein the at least one radio transponder comprises at least one second inspection unit, the at least one second inspection unit being cyclically reset by a signal from the first inspection unit.
