Claim 0:
1. A method for monitoring operating parameters in a passenger transport installation having a plurality of sensors detecting different ones of the operating parameters as well and a signal processing device, the method comprising the steps of:
repeatedly detecting a first of the operating parameters with a first of the sensors;
triggering a second of the sensors only in response to the first operating parameter assuming a predetermined trigger characteristic;
detecting a second of the operating parameters with the second sensor and transmitting a signal reproducing the detected second operating parameter to the signal processing device in response to the triggering; and
processing the signal to monitor the second operating parameter; wherein the first sensor is a current sensor connected to a main power supply and the second sensor is an acceleration sensor or a microphone measuring operating parameters of the passenger transport installation.
