Elevator wireless communication infrastructure using piconet modules

摘要

An elevator system has on each floor hall call buttons that are inter-connected with piconet modules ( 15 ), such as modules conforming to BLUETOOTH(TM) specifications; similar piconet modules ( 16 ) may be associated with hall fixtures such as lanterns and gongs; similar piconet modules ( 50 ) may be associated with hoistway doors, on each floor, so as to form a wireless communication system with a similar piconet module ( 19 ) at the controller ( 18 ); and a piconet module ( 40 ) may be associated with the car operating panel. A module ( 43 ) may be interconnected with the car door lock switch; a module ( 44 ) may be interconnected with a safety switch; modules ( 48 ) and ( 49 ) may be interconnected with lower and upper limit switches; and a module ( 49 ) may be interconnected with an overspeed detector, so as to form a safety chain. A prospective passenger ( 53 ) may carry a portable device with a piconet module ( 54 ) to request elevator service and receive acknowledgment, and maintenance personnel ( 58 ) may use a personal ditigal assistant having a piconet module ( 58 ) therein to acquire current and historical information about the elevator and to issue executable commands to the elevator system.
