Abstract

The invention relates to a method and a system for detecting, transmitting, and analyzing at least one safety-related signal (S1 . . . Sn), wherein the at least one safety-related signal (S1 . . . Sn) is detected using at least one detection unit (EE1 . . . EEn) and is transmitted to at least one analyzing unit (AE1 . . . AE4) via a radio system (FS). In order to simplify the detection of safety-related signals and improve the transmission thereof via a faulty radio path, at least two safety-related signals (S1, S2) are independently detected and transmitted to the analyzing unit (AE1 . . . AE4) via the radio system (FS) so as to allow a dangerous action to be carried out, and an output signal (FRS) for allowing a dangerous action to be carried out is generated by logically combining the received safety-related signals (S1 . . . Sn).

Claims

1-61. -61. (canceled)

62. A system (SYS3) for the detection, transmission and analysis of safety-related signals (S1 . . . Sn) with at least one safety-certified detection unit (ZMEE), at least one radio stretch (FS) and at least one safety-certified processing unit (ZMVE), whereby the safety-certified detection unit (ZMEE) has at least one safety-related input (SnI), operating inputs/outputs (BnI, BnO) as well as a transmission/reception unit (TR5) for wireless communication via the radio stretch (FS), and whereby the safety-certified processing unit (ZMVE) comprises safety-related inputs/outputs (SnI, SnO) and operating inputs/outputs (BnI, BnO),

wherein the safety-certified detection unit (ZMEE) as well as the safety-certified processing unit (ZMVE) each comprise a universal data interface (UDIEE, UDIVE), that an input of the universal data interface (UDIEE, UDIVE) is connected to an output of a client-specific module that makes a client-specific interface (KSI) available on the input side, that the safety-certified system makes available a fixed and/or a variable bandwidth for the transparent transmission of non-safety-relevant data, and that the data is inserted into and/or taken away from hardware by superposed multiplexing or inserted into and/or taken away from software by packing into and/or packing out of a transmission protocol.

63. The system according to claim 62, wherein an analog output such as an analog voltage output and/or a serial input/output such as RS232 is made available via the universal data interface (UDIEE, UDIVE).

64. The system according to claim 62, wherein the universal data interface (UDIEE, UDIVE) can be adapted to a client-specific application in hardware and/or software.

65. The system according to claim 62, wherein the universal data interface (UDIEE, UDIVE) is connected via a data protection module (DSMC) for control data to a multiplexer/demultiplexer (MUX) whose output is connected to a transceiver (TR4, TR5).
