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:
An elevator system having cars in service at top and bottom in a single shaft with efficient group control. The elevator system is provided with a shaft assignment finalizing unit for selecting a shaft and a car to be assigned to a new call, and a reassigning unit for reassigning a car as necessary when a new call occurs after assignment is performed. After tentative assignment is finalized, if a new call is generated before a time for finalizing a stop of a tentatively assigned car is reached, then the tentative assignment is reviewed. If it is determined that reassigning of cars is necessary for a call, then the reassigning unit changes car assignment to the call. Assignment of a car is finalized by the car assignment finalizing unit, and information regarding a final decision is displayed by a display controller.
Abstract:
In a vertically movable elevator group management control apparatus for control of a plurality of transversely shiftable cars among plural shafts, control is done by storing route data with respect to each said car, generating target floor data including a target floor, based on car call data obtained in correspondence with each said car and station call data as obtained correspondingly to each floor, estimating the time taken for said car to reach said target floor, based on at least said route data, said target floor data and said car call data, and assigning a certain car to a certain floor call, based on the estimated arrival time.
Abstract:
An object of the present invention is to provide an elevator system, wherein the allocation of a plurality of elevator cars is determined on the basis of the information inputted from the inside and outside of the elevator cars to thereby increase the operating efficiency of the elevator cars and save a space in a building occupied by the elevator system. In addition, another object of the present invention is to provide an elevator system, in which a destination floor can be selected by numeral input at the inside or outside of an elevator car. Further, a further object of the present invention is to provide an elevator system, in which a stop preferential order of elevator cars can be varied according to the number of standby passengers determined at the outside of the elevator cars. Furthermore, a still further object of the present invention is to provide an elevator system capable of calculating the average number of passengers of an elevator car at respective floors. According to the present invention for achieving the objects, there is provided an elevator system for controlling a plurality of elevator cars, wherein the plurality of elevator cars are arranged in at least one hoist way and driven individually, and speed of the plurality of elevator cars are independent of each other.
Abstract:
An improved elevator system and control method thereof is provided for effectively scheduling elevator cars and reducing hoistway spaces. The elevator system of the present invention includes at least one hoistway and at least two elevator cars operating independently in the hoistway. The elevator system schedules multiple elevator cars for multiple calls on the basis of information obtained by analyzing various signals provided from the button panels installed at elevator cars and elevator entrances of a building, thereby improving operation efficiency of the elevator system.
Abstract:
If a front car arrives in response to a car call and a landing call is assigned to a rear car in the same hoistway for the same floor and the same direction as the car call, a user who needs to board the rear car to which the landing call is originally assigned may erroneously board a car that has arrived at a car call destination in response to the car call. In an elevator system in which a plurality of cars are operated in a coupled or independent manner in a single hoistway, an elevator group-control device includes a front-car car-call detection means for detecting a car call of a front car with respect to its traveling direction out of the plurality of cars or for detecting a floor and a car that are assigned a destination floor of a registered destination floor call; and a rear-car assignment-candidate exclusion means for excluding, from assignment candidate cars, a rear car in the same hoistway as the front car assigned the car call when a landing call for the same direction as the traveling direction is registered at a floor registered by the car call detected by the front-car car-call detection means.
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. The apparatus includes a hall destination floor registration device 4 that is installed in each hall and has a destination floor registration function and a function of providing a predictive indication of a response car for each destination floor, a zone setting section 12 that sets priority zones and a common zone for each of upper and lower cars, an entry determination section 13 that determines whether the upper and lower cars can come into the common zone, a safe waiting section 14 that makes the cars 20 wait safely in accordance with the determination result of the entry determination section 13, a shunting section 15 that makes each car 20 move to a shunting floor as required at the instant when each car finished its service, a confinement time prediction section 16 that predicts a confinement time due to safe waiting when each car is assigned to a destination call generated in a hall, an evaluation value calculation section 17 that evaluates a waiting time, the confinement time, etc., upon assignment of each car, and an assignment section 18 that determines a final assigned car on the basis of the calculation result of the evaluation value calculation section 17.
Abstract:
An elevator group control apparatus to control an elevator system where an upper car and a lower car serve in one shaft and are allowed to go up and down independently. If a new destination call is registered, car travel range calculating means (1b) 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, assignment candidate selecting means (1c) selects or does not select 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, assigning means (1e) determines which car is to be assigned to the new destination call.
Abstract:
An elevator group control device and an elevator group control method can eliminate congestion caused by stoppage, jam or deadlock in a vertical and horizontal movement type elevator system. The vertical and horizontal movement type elevator system controls running of a plurality of cages capable of vertically moving in a plurality of shafts and horizontally moving between the shafts. In the system, path data are stored for each of the cages, target floor data including target floors are produced on the basis of call data obtained correspondingly to the respective cages and platform call data obtained correspondingly to the respective floors, periods of time required for the cages to arrive at the target floor is predicted on the basis of the path data, target floor data, call data and cage data indicative of positions of the respective cages, and predetermined cages are allotted to predetermined platform calls on the basis of the predicted arrival time.
