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

Abstract

The invention relates to a method and a system for detecting, transmitting, and analyzing at least one safety-related signal (S 1 . . . Sn), wherein the at least one safety-related signal (S 1 . . . Sn) is detected using at least one detection unit (EE 1 . . . EEn) and is transmitted to at least one analyzing unit (AE 1 . . . AE 4 ) 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 (S 1, S 2 ) are independently detected and transmitted to the analyzing unit (AE 1 . . . AE 4 ) 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 (S 1 . . . Sn).

         62 . A system (SYS 3 ) for the detection, transmission and analysis of safety-related signals (S 1  . . . 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 (TR 5 ) 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 (TR 4 , TR 5 ).
