Abstract:
A multi-car ropeless elevator system includes at least one lane. An elevator car is arranged in the at least one lane. A linear motor system includes a plurality of stationary motor primary sections extending along the at least one lane and at least one moveable motor secondary section mounted to the elevator car. A plurality of sensors is operatively connected to the linear motor system. Each of the plurality of sensors is operatively associated with a corresponding one of the plurality of stationary motor primary sections. A sensor failure detection and fusion system is operatively connected to each of the plurality of sensors. The sensor failure detection and fusion system operates to identify failures in one or more of the plurality of sensors and fuse data received from remaining ones of the plurality of sensors.
