Patent number: 8439169Abstract: An elevator group supervision controlling apparatus has a response time predicting means, a passenger movement estimating means, a standby time predicting means, a candidate car selecting means, an allocating means, and an instructing means. The response time predicting means predicts response time to a car call from a remote call registering apparatus for respective cars. The passenger movement estimating means estimates passenger moving time based on a positional relationship between the remote call registering apparatus and a landing. The standby time predicting means predicts the standby times of each of the cars based on the response time and the passenger moving time. The candidate car selecting means includes cars for which standby time is shorter than a predetermined time interval in candidate cars, and excludes cars for which standby time is greater than or equal to the predetermined time interval from the candidate cars.Type: GrantFiled: August 25, 2008Date of Patent: May 14, 2013Assignee: Mitsubishi Electric CorporationInventors: Mitsutoshi Iio, Shiro Hikita

Patent number: 8286755Abstract: In an elevator system floors each include: a hall registration device that places a plurality of car calls for moving a car to destination floors different from one another; and a display device that displays the car that has been assigned the plurality of car calls. A limit value setting mechanism sets, for each of the plurality of floors separately, a limit value for limiting a count of the plurality of car calls that can be assigned to the same car. A count-up mechanism obtains, when a new car call is made, a call count of each car by a given method, based on information about the plurality of car calls that have been assigned to the car. A candidate car selector compares the limit value set to a floor where the new car call is made and the call count of the each car, to thereby select, as a candidate car, the car to which the new car call can be assigned from among the cars.Type: GrantFiled: May 23, 2007Date of Patent: October 16, 2012Assignee: Mitsubishi Elelctric CorporationInventors: Masaharu Eto, Shiro Hikita
