METHOD AND SYSTEM FOR THE DETECTION, TRANSMISSION, AND ANALYSIS OF SAFETY-RELATED SIGNALS

摘要

The method involves detecting two safety-related signals by detection units (EE1, EE2) independently. The safety-related signals are transmitted to an analyzing unit (AE1) through a radio system (FS) such that dangerous action to be carried out is allowed by an output signal. The output signal is generated by logically combining the received safety-related signals, and a timing of signal transmission is given by the analyzing unit. The detection units are checked sequentially using a unique identification of the analyzing unit. An independent claim is also included for a system for detecting, transmitting and analyzing safety-related signals.
