Method and system for the detection, transmission and analysis of safety-related signals

A method for the detection, transmission and analysis of at least one safety-related signal (S1 . . . Sn), whereby the at least one safety-related signal (S1 . . . Sn) is detected with at least one detection unit (EE1 . . . EEn) and transmitted via a radio system (FS) to at least one analysis unit (AE2),

• wherein the safety-related signal (S1 . . . Sn) emitted by the at least one detection unit (EE1 . . . EEn) is received by transceiver units (TRA1 . . . TRAn) arranged in a spatially distributed manner, whereby the transceiver units are connected via a bus system (BUS) to a processing unit (VE2) of the analysis unit (AE2), wherein the processing unit (VE2) cyclically transmits a message in the form of a frame (TOKEN) into the ring bus (BUS), and wherein the frame (TOKEN) is processed by each transceiver unit (TRA1 . . . TRAn) which has received a valid radio message, whereby a first transceiver unit (TRA) enters the received data into the frame (TOKEN) and replaces an RSSI value and a reception identification character (RxID) if a reception quality of the transceiver unit (TRA1 . . . TRAn) is greater than a reception quality indicated via a frame cyclically received by the receiver unit.
