Patent number: 7740111Abstract: An elevator group control system for controlling multiple elevators cars each of which serves a plurality of floors includes a route preparation section which, at a time of assigning a hall call to one of the elevator cars, calculates a future trajectory for each of the elevator cars. The future trajectory for each elevator is for a case in which the hall call is assigned to the elevator car. A selecting unit which determines a selected one of the elevator cars to which the hall call is to be assigned using the calculated future trajectories.Type: GrantFiled: July 22, 2009Date of Patent: June 22, 2010Assignees: Hitachi, Ltd., Hitachi Mito Engineering Co., Ltd.Inventors: Toshifumi Yoshikawa, Satoru Toriyabe, Takamichi Hoshino, Atsuya Fujino, Shunichi Tanae, Hiromi Inaba, Kenji Yoneda, Toru Yamaguchi, Ryo Okabe

Patent number: 7730999Abstract: An elevator group control system includes a reference route generating portion, which for each elevator, generates a reference route which the elevator should follow with respect to the time axis and position axis; and an assignment portion which selects an elevator for assignment to a generated hall call so as to make the actual trajectory of each elevator closer to its reference route. Reference routes which guide the cage's trajectory into temporally equal interval condition are generated, and car assignment is executed to allow the cages to settle in temporally equal interval condition over a long period of time.Type: GrantFiled: August 5, 2008Date of Patent: June 8, 2010Assignees: Hitachi, Ltd., Hitachi Mito Engineering Co., Ltd.Inventors: Toshifumi Yoshikawa, Satoru Toriyabe, Takamichi Hoshino, Atsuya Fujino, Shunichi Tanae, Hiromi Inaba, Kenji Yoneda, Toru Yamaguchi, Ryo Okabe

Patent number: 7562746Abstract: A method and a display for elevator allocation evaluating are provided. When an elevator allocated to a hall call is selected by employing two different view points such as a real and a future call evaluation index, an elevator allocation reason and a balance between the two view points can be easily grasped. An elevator allocated to a hall call is evaluated on orthogonal coordinates in which the real call evaluation index and the future call evaluation index are defined as an X and a Y coordinate axis. Evaluation indexes of first to fourth elevator cars are evaluated by employing contour lines of a synthetic evaluation function, which is represented as the real and the future call evaluation index. A weight for allocating is displayed visually.Type: GrantFiled: February 17, 2006Date of Patent: July 21, 2009Assignees: Hitachi, Ltd., Hitachi Mito Engineering Co., Ltd.Inventors: Toshifumi Yoshikawa, Satoru Toriyabe, Takamichi Hoshino, Shunichi Tanae, Atsuya Fujino, Ryou Okabe, Masaya Furuhashi, Kenji Yoneda

Patent number: 6408986Abstract: An elevator capable of supplying electric power to accessory hall devices such as up/down elevator buttons and position indicators without requiring power supply lines between the cage and each hall. A drive battery which supplies electric power to hall devices provided in each hall and a receptor connected to the battery are provided on the hall. A feeder contactable with the respective receptors, a charging device that charges the battery via the feeder and receptor are provided on the top of the cage.

Patent number: 5409085Abstract: The present invention relates to a group control elevator system which has been adjusted to operate in response to a state of utilizing elevator cars. In a group control elevator system which carries out a control of allocating elevator cars to elevator car calls for serving many floors by using an evaluation function having a plurality of variable parameters, targets for elevator control performance are inputted, a traffic flow to which elevator car demand belongs is judged, variable parameters to be adjusted which have been set in advance for each combination of said targets and traffic flows are stored, stored variable parameters are adjusted, adjustment sequence of variable parameters to be adjusted is stored, and a plurality of variable parameters are sequentially adjusted according to the stored sequence. By the above arrangement, only desired parameters to be adjusted are selected and adjusted out of a plurality of variable parameters for desired targets and traffic flows.Type: GrantFiled: November 24, 1993Date of Patent: April 25, 1995Assignee: Hitachi, Ltd.Inventors: Atsuya Fujino, Toshimitsu Tobita, Hiromi Inaba, Kiyoshi Nakamura, Yoshio Sakai, Kenji Yoneda, Hiroaki Yamani
