Sensor network for a passenger transport system

A sensor network for a passenger transport installation, the sensor network comprising:

• a master unit;
• a signal transmission means;
• a plurality of sensor nodes in signal communication with the master unit through the signal transmission means;
• a plurality of sensors each for detecting a physical measured variable of the passenger transport installation and wherein each of the sensor nodes includes at least one of the sensors and transmits the detected measured variable to the master unit by the signal transmission means;
• wherein the master unit includes a sensor detection module that determines an identity of the sensors included in the sensor nodes by using information previously stored in a database;
• and
• wherein the information previously stored in the database is at least one of,
• (i) a first type of information comprising information about reference measurement results to be typically provided under known conditions by particular sensors to be installed in the passenger transport installation,
• (ii) a second type of information comprising information about an identity of particular sensor nodes to be installed in the passenger transport installation, the identified particular sensor nodes comprising a plurality of different ones of the sensors or a plurality of same ones of the sensors in different configurations, and
• (iii) a third type of information comprising information about a pre-established configuration of particular sensor nodes to be installed in the passenger transport installation, the configured particular sensor nodes comprising a plurality of different ones of the sensors or a plurality of same ones of the sensors in different configurations.
