Patent number: 11208295Abstract: An arrangement of counting passengers in an elevator using two separate counting mechanisms is disclosed. The elevator car typically has a curtain of light arranged to the door and a load weighing device arranged to measure the weight of the elevator car. From the information recorded by the curtain of light and the load weighing device, it is possible to count the number of passengers. The reliability of the counting results can be improved by processing the counting results for forming a combined counting result that provides a more reliable counting result when the independent counts deviate from each other.Type: GrantFiled: January 17, 2019Date of Patent: December 28, 2021Assignee: KONE CORPORATIONInventors: Marja-Liisa Siikonen, Johan Backlund, Janne Sorsa, Juha-Matti Kuusinen

Patent number: 10227207Abstract: A method for a passenger-allocation in a multi-deck elevator group where the decks of the elevator cars are stacked above each other and being mounted in a car frame to be moved synchronously in an elevator shaft utilizes an improved allocation strategy. The method is performed by a control unit to dispatch the elevator cars for serving any passenger call which can be entered as a landing call or a car call, wherein a call creates plural allocation proposals calculated by an optimization algorithm carried out by the control unit for dispatching an elevator to a passenger call. The allocation proposals are then processed in a routing algorithm defining one serving deck to be taken for the allocation of a specific call, which routing algorithm is restarted for any further incoming call independent of whether a further incoming call is creating new elevator allocation proposal(s) or when a reallocation timeout has passed. A computer program carrying out the method is further disclosed.Type: GrantFiled: January 28, 2016Date of Patent: March 12, 2019Assignee: KONE CORPORATIONInventors: Janne Sorsa, Marja-Liisa Siikonen
