Abstract: An operation control method of plural elevators working between many floors is constructed so that a risk floor having a high probability that a long wait occurs is selected from among floors on which a platform call is not generated when a platform call is newly generated, assuming that along with the newly generated platform call a platform call is generated on the risk floor, allocation evaluations are made on the cases of allocating respective elevators to render services to these calls, an elevator to respond to the new platform call is decided based on the allocation evaluation result, and the plural elevators are controlled to be operated based on this decision.

Abstract: An elevator group management controller, that: predicts an arrival time each elevator car can arrive from a present position to a floor where a hall call is generated; estimates a travel distance for each car from its present position to stop in response to every car call to be handled by the car; calculates a waiting time with respect to the hall call based upon the predicted arrival time, for evaluating a waiting time by employing a first evaluation function while the waiting time is employed as an evaluation index, and for evaluating a travel distance by employing a second evaluation function employing the estimated travel distance as an evaluation index; and calculates an integral evaluation function containing at least the waiting time evaluation and travel distance evaluation for each car, and assigns a car whose integral evaluation function value is minimum with respect to the hall call.

Abstract: A building is provided with a plurality of service zones each including a plurality of floors, and elevators each assigned to the floors included in a corresponding one of the service zones as service floors. The service zones are provided such that the floors included in each of the service zones are at least partially different from the floors included in each of the other service zones. In an event of a fire in the building, an evacuation control apparatus for the elevators controls the elevators to convey those stranded in the building to a common evacuation floor.

Abstract: It is an object of the present invention to provide a control apparatus for a one-shaft multi-car system elevator in which a plurality of cars operate in one shaft, the control device being capable of efficient group control while avoiding collisions and minimizing the occurrence of confinement of passengers. The control apparatus includes approaching direction traveling prohibiting means 1D for prohibiting the cars from traveling in a direction in which the cars approach each other in the same shaft, and door open standing-by means 1E for causing the car to stand by with its doors open if the car is prohibited by the approaching direction traveling prohibiting means from traveling and if any passenger is present in the car.

Abstract: In an elevator group supervisory control apparatus, an estimation processing unit determines an estimated in-cage load in departing from a departure floor and estimates at least one of speed, acceleration, and jerk rate of the car in accordance with the estimated in-cage load to determine an estimated arrival time. An assignment unit selects and assigns a car serving as a response to a hall call on the basis of information from the estimation processing unit when the hall call is issued.

Abstract: The invention relates to a triple-deck elevator equipment planning support system, arranged such that the average number of times of being stopped per going-round is calculated on the basis of a given building specification and cage specification data in a triple-deck elevator system; a total value of getting-on/off time periods of passengers, a total value of door-opening/closing time periods, and the total value of running time periods are calculated based on the average number; and a going-round time period of an elevator is calculated from these calculation results, and a practical transportation capacity per on triple-deck elevator is calculated.

Abstract: An elevator group supervisory control apparatus is obtained which can achieve efficient group supervisory control while preventing or reducing the possibility of collision and the safe stopping of an upper car and a lower car in one and the same shaft as much as possible.

Abstract: An elevator group control apparatus collectively controls an elevator system where at least two cars can travel in each shaft independently of each other. The apparatus has a destination floor registration device installed at each hall for passengers to register destination floors and to indicate to passengers which cars will serve respectively for the registered destination floors. Priority zones and a shared zone for upper cars and for lower cars are set; a judgment is made as to whether the shared zone set can be entered by an upper or lower car; a car is put on standby based on the judgment a car is sent to a withdrawal floors, as necessary, after a service is completed. A car is selected as a candidate for assignment to a destination call if, according to the destination to be served by each car and the zones set for each car, so that the car would cause neither collision nor safety stop; and a car is assigned based on the selection.

Abstract: An elevator group control apparatus to control an elevator system in which an upper car and a lower car serve in a single shaft and go up and down independently. If a new destination call is registered, a car travel range calculator provisionally assigns a car to the new destination call and calculates the travel range of the provisionally assigned car and the travel range of the other car in the same shaft. Based on the calculated travel ranges, an assignment candidate selector selects or rejects the car as a candidate for assignment to the new destination call. Later, several evaluation index values are calculated for each of the selected candidate cars. By comprehensively evaluating these calculated evaluation index values, a determination is made as to which car is to be assigned to the new destination call.

Abstract: In a multi-deck-elevator-equipped building control system, operating modes of an elevator control portion include a double operating mode. In the double operating mode, only a first cage is permitted to stop at first cage stop floors, and only a second cage is permitted to stop at second cage stop floors that are distinct from the first cage stop floors. A building fixture control portion has a first group control portion for associatively controlling an electrical fixture on the first cage stop floors and a second group control portion for associatively controlling an electrical fixture on the second cage stop floors.

Abstract: In an elevator system, an evacuation elevator control portion devises an evacuation plan making use of elevators based on disaster information in the event of a disaster, and outputs a command to perform evacuation operation, which is based on the evacuation plan, to an elevator operation control portion. The evacuation elevator control portion monitors an evacuation situation resulting from evacuation operation, and transmits information on the evacuation situation to the outside.

Abstract: Provided is a fire evacuation operation system for group-controlled elevators which enables a large number of people to evacuate in a short time.

Abstract: An elevator control device which realizes, in a multi-car system, operation control superior in transportation efficiency. A first shunting device outputs a first shunting command for moving a car which has responded to a call request to a shunting floor. A blocked state detection device detects a blocked state in which a succeeding car cannot run due to a preceding car being in a standby state at a shunting floor, and outputs blocked-state-generation information. A second shunting device outputs a second shunting command for moving the preceding car in the standby state to a new shunting floor based on the blocked-state-generation information. Further a collective operation control device collectively controls the operation of each car based on information for each car, the first shunting command from the first shunting device, and the second shunting command from the second shunting device.
