Abstract:
An elevator system includes at least one shuttle elevator and at least two local elevators, the elevator cars of which are arranged to travel in the same elevator hoistway such that they can serve at least one shared transfer floor of a transfer level. The control system of the elevator system receives destination calls given from a destination call appliance, forms a plurality of route alternatives and allocates a destination call to one or more elevators by selecting the best route alternative. When allocating a destination call, the control system takes into account that the elevator cars of the local elevators that travel in the same elevator hoistway cannot simultaneously be at a shared transfer floor in cases in which the route alternative includes a part-trip with a local elevator and a change of elevator at a shared transfer floor.

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:
A method and a display for elevator allocation evaluating are provided. When an elevator allocated to a hall call is selected by employing two different view points such as a real and a future call evaluation index, an elevator allocation reason and a balance between the two view points can be easily grasped. An elevator allocated to a hall call is evaluated on orthogonal coordinates in which the real call evaluation index and the future call evaluation index are defined as an X and a Y coordinate axis. Evaluation indexes of first to fourth elevator cars are evaluated by employing contour lines of a synthetic evaluation function, which is represented as the real and the future call evaluation index. A weight for allocating is displayed visually.
Abstract:
A procedure for allocating the calls entered via landing call devices of the elevators in an elevator bank forms several allocation options. Each allocating option contains, for each active landing call, a call data item and an elevator data item which together are used to determine which elevator should service the call. The value of a cost function is calculated for each allocation option; one or more of the allocation options is repeatedly changed with respect to at least one data item, and the values of the cost functions of the new allocation options are calculated. Based on the values of the cost functions, the best allocation option is selected and the active elevator calls are allocated to the elevators in the elevator bank accordingly.
Abstract:
An elevator car dispatcher having an artificially intelligent supervisor which generates a crowd prediction signal associated with a particular floor, monitors a condition of a first elevator car which has serviced the predetermined floor and controls the remainder of elevator cars assigned to the predetermined floor dependent upon the condition of the first car.
Abstract:
A service estimation apparatus for an elevator adopting an estimated index with which service by the elevator can be estimated in any building and under any traffic state comprising a measurement apparatus to measure periods of service time and a microprocessor operating under program control to calculate a mean value and a variance of the periods of service time to set a reference value for designating a range of the periods of service time and to determine the estimated index, namely, an upper limit presumption value based on the mean value, the variance, and the reference value, and to determine an unachieved rate of service reference corresponding to the upper limit presumption value, the unachieved rate of service reference being a probability value at which the elevator periods of service time fall outside the range designated by the reference value.
Abstract:
A group supervision apparatus for an elevator has apparatus operating under program control to predict periods of time of service by respective cages and to calculate predicted service periods of time, to calculate a mean value and a variance of the predicted service periods of time as to each of the cages, to set a reference value for deciding whether the service periods of time are long or short, to obtain a square value of a difference between the reference value and the mean value, to calculate a value of a ratio between the variance and the square value and to calculate an assignment estimation value on the basis of the value of the ratio in conformity with a predetermined assignment estimation function which becomes a monotonically increasing function of the ratio, to preferentially select a cage as to which the assignment estimation value is smaller, and to assign the selected cage to a hall call.
Abstract:
A group control assigns elevator cars to floor calls optimized in such a manner, that minimal waiting times result and the elevating capacity is increased. A computing device provided for each elevator calculates at every floor a sum proportional to the time losses of the waiting passengers from the distance between the floor and the car position as indicated by a selector, the intermediate stops to be expected within the distance and the instantaneous car load. By means of call registering devices in the form of ten key keyboards at the floors, it is possible to enter calls for destination floors, so that at the time of calculation, the floor calls and the car calls are available simultaneously. The calculated lost time sum, also called servicing costs, is stored in a cost memory provided for each elevator. During a cost comparison cycle, the servicing costs of all elevators are compared with each other by way of a cost comparison device where in each case an assignment instruction can be stored in an assignment memory of the elevator with the lowest servicing costs which instruction designates that floor to which the respective car is optimally assigned in time.
Abstract:
An elevator control system for controlling a plurality of elevators in an elevator bank includes a processor in communication with a non-transitory memory, and a networking device. The processor executes software instructions that cause the elevator control system to receive an elevator call placed by at least one of a user and a mobile device of the user. The elevator control system wirelessly communicates with the mobile device to determine an elevator criteria set by the user on the mobile device via an elevator control application. The elevator criteria comprises a preference and a requirement. The software instructions allow the processor to determine whether an elevator in the elevator bank meets the requirement and the preference, and an elevator that meets at least the requirement is automatically assigned to the user.
