Patent number: 8839914Abstract: An elevator system capable of an efficient evacuation using an elevator in case of a fire, and capable of confirming an evacuee remaining status in a case that an evacuation operation using the elevator is discontinued. An evacuation-call response-order setting section sets a priority order of a response to an evacuation special call registered in an evacuation special call registration section, based on fire occurrence information received by a fire situation reception section. A responding floor is selected based on the priority order. The evacuation operation running section controls an operation of the elevator so as to direct a car to the responding floor selected in this manner. In a case that the evacuation operation availability determination section determines that the evacuation operation is not available, the evacuation operation terminating section causes an evacuation special call remaining floor display section to display a remaining evacuation special call registration floor.Type: GrantFiled: January 18, 2010Date of Patent: September 23, 2014Assignee: Mitsubishi Electric CorporationInventors: Masafumi Iwata, Masahiko Konishi, Kiyoji Kawai, Toshiyuki Kodera, Akihisa Miyajima
