Patent number: 10407085Abstract: A train travel prediction device includes a required time database that records a station-to-station required timetable created in advance between stations and indicating a relation of a time difference between a last station departure time of a target train and a next station departure time of a precedent train with respect to a required time of the target train to a next station by the use of a train simulation on the basis of a train moving condition and an operation prediction unit that creates a prediction schedule on the basis of information of the required time acquired for each target train during a prediction period by referring to the station-to-station required timetable recorded in the required time database on the basis of information of a train schedule and a train arrival-departure time.Type: GrantFiled: April 21, 2014Date of Patent: September 10, 2019Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Yasuyuki Kawabata, Yusaku Nagasaki, Koki Yoshimoto

Patent number: 10053122Abstract: When it is determined that a control-target train has an impact on a third train that is other than a train that is determined to affect the control-target train, a ground running control unit of a train-running management device further changes a running pattern and instructs the control-target train to take less time to completely leave a departure station.Type: GrantFiled: February 7, 2014Date of Patent: August 21, 2018Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Masashi Hagiwara, Yusaku Nagasaki, Koki Yoshimoto

Patent number: 9646272Abstract: A technique which comprehensively optimize passengers' convenience and a power consumption amount. An operation schedule evaluation apparatus has a passenger flow calculator and a power consumption amount calculator. The passenger flow calculator creates passenger flow information related to a passenger flow generated by transportation of a train, based on operation schedule information of each train and passenger information related to an entry and an exit of a passenger at a station. The power consumption amount calculator calculates the number of passengers or a car occupancy of each train based on the passenger flow information created by the passenger flow calculator, the operation schedule information and car information of each train, and calculates a power consumption amount of each train per unit time which reflects car weight corresponding to the number of passengers or the car occupancy.Type: GrantFiled: October 29, 2013Date of Patent: May 9, 2017Assignee: Mitsubishi Electric CorporationInventors: Atsuko Aoki, Kenji Ueda, Satoru Takahashi, Masahiko Tanimoto, Yusaku Nagasaki

Patent number: 9642163Abstract: A train control device includes an on-vehicle base station mounted on a train, base stations that can communicate with the on-vehicle base station, an on-vehicle control device controlling an operation such that the train can stop before reaching a stop limit before which the train can run safely, and ground control devices that transmit, to the train side, the stop limit calculated based on information on the current position acquired from the train side via the base stations and opening information on a turnout on the ground. The on-vehicle control device calculates a channel-reservation start pattern, which is a pattern determining a reservation start position of a communication channel of a base station as a switching target when the base station as a communication partner to the on-vehicle base station is switched and in which the reservation start position is different according to train speed and train position.Type: GrantFiled: June 11, 2013Date of Patent: May 2, 2017Assignee: Mitsubishi Electric CorporationInventors: Yusaku Nagasaki, Masashi Asuka, Atsushi Takami

Patent number: 8967553Abstract: In accordance with a predetermined segment definition rule based on a point-switch protection section, a point switch control direction, and a train advancing direction, a plurality of segments are defined in advance with respect to a railway network. Segment competition information in which a competitive relationship between the plurality of segments is set in advance is prepared. A segment use permission setting part determines whether or not a competition for a use-requested segment in terms of a train operation occurs between the plurality of trains, by using segment competition information and segment use permission status information. A use-requested segment for which it is determined that no competition occurs is incorporated, as a use permission segment, into use permission segment information of the corresponding train. In accordance with a result of the competition determination, the segment use permission status information is updated.Type: GrantFiled: November 15, 2011Date of Patent: March 3, 2015Assignee: Mitsubishi Electric CorporationInventors: Masashi Asuka, Satoru Takahashi, Koki Yoshimoto, Atsushi Takami, Yusaku Nagasaki
