Abstract: The detection of traffic demand for elevator cars serving a plurality of floors is related. A device is provided for detecting the latest information on traffic demand based on the number of passengers actually boarding and alighting from cars (herein-after referred to as the "boarding and alighting passengers"). On the basis of the respective floors at which cars are stopped to serve, the direction of travel of the cars, and the number of passengers boarding and alighting from the cars at the respective floors, the number of boarding and alighting passengers by direction is detected for each floor. The detected numbers for the respective floors are totaled to detect the traffic demand at each floor by direction. Further, the total is made for each traffic demand pattern to detect the traffic demand at each floor by traffic demand pattern and by direction.

Abstract: An elevator car group control system for controlling a plurality of elevator cars arranged for parallel operation for serving a plurality of service floor landings of a building, comprising means for selecting suitable ones of the cars for serving hall calls, and means for forecasting the length of time required for each of the selected cars to arrive at each of the allotted hall call originating floors and displaying the forecast waiting time on display means disposed at the landing of each of the floors. In the invention, the serving car selecting means comprises means for detecting for each car the number of floors subject to change in forecast waiting time displayed at each of the already allotted floors when a new hall is originated from one of the floors, and means for preferentially selecting the car detected to provide a smaller number of floors subject to such change than the others.

Abstract: In an elevator system comprising a plurality of elevator cars serving a plurality of floors in response to hall calls and cage calls, an elevator control apparatus is provided which comprises a device for forecasting cage calls as a new type of traffic information expected to be registered as hall waiting passengers take a given car. The device includes means arranged on each hall for detecting the number of prospective passengers waiting on the particular hall and means for setting the ratios of the hall waiting passengers destined for respective floors. The detected number of hall waiting passengers is multiplied by the ratios of destination floors (hereinafter referred to as "destination ratios") to figure out floors to which the hall waiting passengers joining the car are most likely to proceed, thus forecasting a corresponding cage call or calls.

Abstract: An elevator control system for controlling a plurality of elevator cars arranged for parallel operation for servicing a plurality of service floor landings of a building, in which means are provided so that, in response to origination of a new hall call in addition to hall calls originated and allotted already, a suitable car for servicing this new hall call can be selected and the new hall call can be allotted to the selected car to be serviced by the selected car. In the system, the change in the service condition of all the cars for the already allotted hall calls due to allotment of this new hall call thereto is taken into account in selecting the suitable car. For example, means are provided for computing for each car the forecast waiting time at each of the already allotted floors to be serviced thereby to detect the change in the forecast waiting time when this new hall call originating floor is serviced.

Abstract: An elevator control apparatus is provided with means for detecting a new type of elevator car traffic information consisting of the information indicating, by allotting the passengers in the car to resistered cage calls, how many passengers classified for each of destination floors are in the car, namely, the information indicating the number of in-cage passengers classified for each of destination floors. In an apparatus comprising means for allotting a hall call generated to an optimum one of a plurality of cars and means for detecting the number of prospective passengers waiting on the floors, the number of prospective passengers waiting at the floor the hall call from which is allotted to the car and the number of passengers classified for each of destination floors are added to or subtracted from the number of passengers in the car for each floor involved thereby to forecast the number of in-cage passengers in the leading floors.

Abstract: Elevator cars for servicing a plurality of floors are under the control of register means provided at elevator halls to registrate the hall calls for the up- and down-directions. Detector means are installed at the elevator halls to detect the number of the passengers awaiting the cars at the halls. Discriminator means are employed to obtain the information concerning the number of the car awaiting passengers classified for each of the directions of their destinations. The information thus obtained is utilized in the elevator control apparatus to operate the elevator system with a high working efficiency. When the hall calls for one direction are registrated, the detected number of the car awaiting passengers is regarded as the number of the awaiting passengers for the hall calls of the above one direction.
