Abstract:
1. A sensor network for state monitoring of a wind turbine, the sensor network comprising: one or more standard sensor modules, each standard sensor module including a sensor configured for measuring a standard parameter related to normal operation of the wind turbine or its surroundings at regular intervals or on an on-going basis; a processor configured for receiving input from said one or more standard sensor modules; and a data transfer channel configured for transferring sensor output from said one or more standard sensor modules to said processor, said data transfer channel including one or more auxiliary connection points that are free during the normal operation of the wind turbine for connection of one or more additional sensor modules configured to measure a non-standard parameter, and said one or more additional sensor modules being in surplus of the one or more standard sensor modules in a standard set-up of the wind turbine sensor network.
