Abstract:
An elevator group supervision controlling apparatus has a response time predicting means, a passenger movement estimating means, a standby time predicting means, a candidate car selecting means, an allocating means, and an instructing means. The response time predicting means predicts response time to a car call from a remote call registering apparatus for respective cars. The passenger movement estimating means estimates passenger moving time based on a positional relationship between the remote call registering apparatus and a landing. The standby time predicting means predicts the standby times of each of the cars based on the response time and the passenger moving time. The candidate car selecting means includes cars for which standby time is shorter than a predetermined time interval in candidate cars, and excludes cars for which standby time is greater than or equal to the predetermined time interval from the candidate cars. The allocating means decides an allocated car from among the candidate cars if at least one of the cars has been included in the candidate cars. The instructing means generates an informing instruction to communicate to the remote call registering apparatus reinput requesting information that recommends an input operation at the landing call registering apparatus if all of the cars are excluded from the candidate cars.
Abstract:
The present invention discloses a method for controlling an elevator system. In the method an elevator is allocated for the use of a passenger in a first optimization phase in such a way that a first cost function is minimized, a second optimization phase is performed, in which the route of the allocated elevator is optimized in such a way that a second cost function is minimized.
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.
Abstract:
An elevator swing operation system for use in a building includes a plurality of floors with landings that are grouped into zones. The elevator cars are allocated to service the zones with a default allocation setup or configuration. The allocation of elevator cars to zones can be modified by moving an elevator car from one zone to another in response to a maximum estimated time to arrival being exceeded and a maximum number of elevator cars allowed to change zones not being exceeded. Furthermore, the default configuration or allocation can be restored when the system is in swing operation, an elevator car is parked, and a minimum time for receiving no calls has been exceeded.
Abstract:
An elevator system which utilizes a plurality of independently moving cabs in each elevator shaft. The lower cabs are connected to spatially separated counterweights in order to prevent interference between cables, pulleys and counterweights. The top cab may be connected to one or two counterweights by connection points on the roof of the cab. The cabs are mounted on tracks, to guide each cab through the elevator shaft. The system includes a motor attached to each of the cabs by lift cables to facilitate the independent movement of all cabs. Existing buildings can be retrofit for compatibility with the present invention. A system and method for controlling the motions of all cabs comprising determining and selecting an optimal cab and a best hoistway range to service passenger requests.
