Abstract:
An elevator group control apparatus includes a parameter calculating unit for determining a weighting factor for an item to be evaluated, which is calculated from a running distance estimated by an estimation arithmetic operation unit by taking into consideration a relation between a running distance of an elevator and a passenger average waiting time, and an evaluation arithmetic operation unit for calculating a total evaluated value from an item to be evaluated of a passenger waiting time, an item to be evaluated of the running distance, and the weighting factor determined by the parameter calculating unit. The elevator group control apparatus selects an elevator whose total evaluated value is the best from among the plurality of elevators, and assigns a hall call to the selected elevator.
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:
A device for controlling a elevator installation with multiple deck cars which are simultaneously accessible at a main stopping point by different main stopping floors includes a call registering device by which a passenger can input a destination floor. In order to enable a more rapid filling of the building, a conversion unit responds to the destination call travel orders already allocated to and/or demanded of the multiple car having the deck which is to be allocated to the passenger to minimize the number of stops of the car. An indicating device indicates to the passenger the allocated car deck and/or the main stopping floor thereof.
Abstract:
During up-peak, a dispatcher selecting method chooses among three dispatching algorithms: (i) an up-peak sectoring scheme triggered when two cars leave the lobby fully loaded, (ii) static sectoring, and (iii) dynamic sectoring, in response to any of three criteria: car load, floor population, and average waiting time, allowing a group of elevators to be operated under any three of the dispatching algorithms, not locked into any two.
Abstract:
A plural elevator system having a group controller for controlling the joint response of a plurality of elevator cars to the needs of a building, employs a microprocessor-based group controller for providing up peak, down peak and other zone-controlled elevator functions. The group controller provides a variable interval between dispatching of elevator cars from the lobby during up peak, the dispatching interval being controlled by the approximate round trip time of an elevator being dispatched from the lobby in serving the car calls registered within it and returning to the lobby, or the average of the approximate round trip time for two or three most recently dispatched elevator cars. The dispatching interval is determined by the approximate round trip time divided by the number of elevator cars serving the up peak traffic. In addition, the dispatching interval can be further reduced in dependence upon the number of cars standing at the lobby, the reduction being greater in case the last car leaving the lobby is not more than half full than in the case when the last car leaving the lobby is more than half full. Exemplary elevator and microprocessor structure, an overall group controller microprocessor program logic flowchart, illustrative of the environment of the invention, and detailed logic flowcharts illustrative of an embodiment of the invention are disclosed.
Abstract:
Controls for multicompartment elevator cars including, one, an arrangement operating while a car is parked and in response to the answering of a hall call for one direction of travel by one compartment to delay for at least a predetermined period the answering of a hall call for the other direction by the other compartment; two, an arrangement for preventing under certain circumstances the registration of certain car calls in each of the compartments of a car; three, an arrangement in which two separate hall call registration devices are provided at a predetermined intermediate landing for indicating desired travel in a particular direction from that landing, one for travel to odd landings in that direction and the other for travel to even landings; four, an arrangement for stopping some of a plurality of two compartment cars with their lower compartments for odd landing hall calls and the rest of the cars with their upper compartments for even landing hall calls; five, an arrangement for preventing both the registration of car calls for even landings in lower compartments stopped for odd landing hall calls and the registration of car calls for odd landings in upper compartments stopped for even landing hall calls; six, an arrangement for transferring selection at a dispatching floor from a selected car to another car in response to an indication that a passenger at that floor desires to travel to a landing which is not served by the compartment of the selected car adjacent the dispatching floor; and seven, an arrangement for transferring selection at a dispatching floor from a selected car to another car in response to the registration of a hall call at a predetermined landing which the selected car cannot answer.
Abstract:
A system and method for controlling multiple elevator cabs in an elevator shaft of a structure, where at least one elevator shaft having a plurality of zones, each zone representing at least one floor of the structure; at least one zone having at least one sensor; at least two elevator cabs moveable within the shaft, each cab moveable independently of other cabs; and a controller that determines movement of each cab into a zone. A first cab preceding any other cab, designated a leading cab; each cab following the leading cab, designated as a trailing cab; each cab moveable in the same direction of travel to service zones until each cab reaches its designated end zone; wherein the controller only instructs a trailing cab to move into a zone with a sensor, after the sensor in the zone detects a cab that was located in such zone has exited that zone thereby preventing collisions.
Abstract:
An elevator controller that enables enhancement in serviceability, avoids a collision between multiple cars that ascend/descend inside a common shaft, and suppresses increase in the number of floors a car cannot reach. The elevator controller includes: multiple cars arranged inside a common shaft such that each car can ascend/descend independently; an occupied area setting mechanism setting, for each of the multiple cars, a maximum area of a travel section necessary for the car to make an emergency stop as an occupied area for the car based on a running speed, a running direction, and a call registration status; and a running speed setting mechanism setting a running speed of a car so a number of floors the car can service is maximized within a range in which the car can make an emergency stop without entering an occupied area set by the occupied area setting mechanism for the other car.
Abstract:
An elevator system includes at least two independently operable elevator cars in each elevator shaft of the system. The elevator shaft may include a first and a second region, with the first region extending from a ground level to sub-ground levels, and with the second region extending from the ground level to a top floor. A first elevator car may move within the first region and a second elevator car may move within the second region, in the same shaft independently of each other.
