Abstract:
A method for assigning an elevator car to respond to a call signal includes a controller that determines which elevator car will respond to the call signal based on certain time metrics. The controller receives a hall call signal, and based on certain time metrics that can include, e.g., an estimated wait time (EWT), and/or estimated travel time (ETT), assigns the call signal to an elevator car. In this example, EWT represents the time a passenger is waiting for an elevator car to arrive, and ETT represents the it takes for a passenger to reach their destination once having boarded an elevator car. In some versions, an estimated time to destination (ETD) is used in determining which elevator car to assign, where ETD represents the sum of EWT and ETT. In some versions, a handling capacity coefficient (HCx), which reflects current traffic conditions, is used in determining which elevator car to assign.
Abstract:
An intelligent destination elevator control system streamlines the efficiency and control of destination elevators. The system monitors a building's population and predicts elevator traffic conditions. The system may monitor attributes of the destination elevators. Based on the monitored data, the system may generate a data structure that renders time-tables and target elevator service quality parameters that may control the destination elevators.

The system comprises first sensor means (2, 2A . . . 2H), which are arranged in the waiting area of each elevator (1A . . . 1H) on each floor (F, F1, F2, F3 . . . Fn), which sensor means (2, 2A . . . 2H) are fitted to give information about the presence and number of passengers waiting for an elevator at least in the waiting area in question; means for controlling the elevators, which means are fitted to receive information from the sensor means (2, 2A . . . 2H) about the presence and number of passengers waiting for an elevator and to control the movement of the elevators of the elevator system utilizing the information received from the sensor means.
Abstract:
An elevator group management system improving operational efficiency in consideration of a situation change that has occurred after a destination floor registration in a hall. An assigned car review mechanism executes assigned car review processing in units of review registration information sets each including at least one piece of provisionally assigned car registration information managed by a registered destination floor hall call management section during a review period. After ending the assigned car review processing, the assigned car review mechanism modifies the contents of the provisionally assigned car registration information in the registered destination floor hall call management section based on the contents of the review registration information set after modification. That is, the assigned car review mechanism newly registers the provisionally assigned car registration information after review and erases the provisionally assigned car registration information before review at the same time.
Abstract:
An exemplary method is useful for handling passenger requests during an elevator system modernization that includes modernizing elevator cars over time. The modernized elevator cars are capable of servicing destination requests placed outside of an elevator car. Such destination requests include an indication of a desired destination. The exemplary method includes assigning an elevator car to respond to a new pending destination request according to a selected criterion for selecting between a modernized elevator car and an elevator car that has not yet been modernized. The method includes automatically updating the selected criterion responsive to a change in a number of modernized elevator cars.
Abstract:
The present invention discloses a method and a system for modernizing at least one elevator group, which comprises a plurality of elevators, a group control that controls the elevator group as well as call-giving appliances connected to the group control via the landing appliance bus. According to the solution a new group control, new call-giving appliances for the floor levels and also a new landing call bus are installed in the elevator group; a new group control is connected to the pushbutton interface of the old call-giving appliances for transmitting calls given by passengers from the new group control to the old group control. The elevator calls given by passengers are divided between the modernized subgroup and at least one unmodernized subgroup on the basis of the given selection criterion, and a call addressed to the modernized subgroup is allocated in the new group control to the modernized elevators or a call addressed to the unmodernized subgroup is transmitted via the pushbutton interface to the unmodernized subgroup.
Abstract:
A method and system determine peak power consumption over time by a bank of elevator for servicing a set of passenger hall calls and delivery requests, and selecting elevator schedules that keep peak power consumption below a predetermined threshold. For each car in response to receiving a hall call, a set of all possible paths to service all hall calls assigned to the car are determined, in which each path includes a set of all possible segments. A peak power consumption for each possible segment is also determined. The peak power consumptions for the set of all possible segments for each time instant are added to determine a total peak power consumption for each time instant, and a particular path is selected as a schedule to operate the bank of elevator cars, if the total peak power consumption for any instant in time while operating according to the selected schedule is below a predetermined threshold.
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 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:
The invention concerns a method for solving an optimization task consisting of a plurality of sub-functions in the control of the operation of an apparatus. In the method, a set of a plurality of solution alternatives is generated and, according to the method, each sub-function is normalized. Normalized cost functions of the sub-functions are generated for each solution alternative for solving the optimization task, and based on the normalized cost functions of the sub-functions, a set of solutions to the optimization task is formed. From the set of solutions, the best solution is selected and the apparatus is controlled in accordance with the solution thus selected.
