US 12,528,525 B2 · Method for monitoring a danger area and monitoring device

Abstract

A method for monitoring a danger area of a railway installation. At least one radio module is arranged in, or in the vicinity of, the danger area. Radio signals are transmitted by the radio module and the radio signals are received and evaluated. A pattern of the received radio signals in a basic state of the danger area is determined and when the radio signals are evaluated, differences from the pattern in the basic state are determined and a response is triggered when the differences exceed a predefined limit value. There is also described a monitoring device. The radio modules are preferably WLAN modules and the danger area is a tunnel. Timetabled breaches of the danger area by trains do not lead to an alarm and the radio modules are functionally tested by determining whether the predefined limit value is exceeded when a train travels through.

A method of monitoring a danger area of a railway installation, the method comprising:

providing at least one radio module in the danger area or in a vicinity of the danger area;
transmitting radio signals by the radio module;
receiving and evaluating radio signals by the radio module;
determining a pattern of the received radio signals in a basic state of the danger area;
evaluating the radio signals by determining differences from the pattern in the basic state and triggering a response when the differences exceed a predefined limit value;
and
following the triggered response, checking whether there exists a planned breach of the danger area based on a timetable of the railway installation.
