摘要:
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.

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.

An elevator control apparatus for moving free elevator cages to optimal stand-by floors determined according to a plurality of fuzzy rules of if-then format. A learning function is employed for altering the parameters of the fuzzy rules based on statistics of past traffic patterns over a pre-determined time period. Free elevator cages are detected by an operation control element and then moved to optimal stand-by floors. A stand-by control element responsive to fuzzy rules generates a signal directed to the operation control element for initiating movement of the free elevator cages.
摘要:
A method for increasing the transportation capacity of elevators in a building involving dividing the elevators (2-7) into two or more groups, each comprising one or more elevators, in such manner that in certain loading situations the groups will temporarily serve different zones (11, 12) of the building (1). Upward peak traffic conditions are detected and the boundaries between zones (11, 12) are determined and maintained by the steps which include:(a) detecting by a peak traffic condition, mainly on the basis of elevator loading time and/or the number of people arriving in an elevator lobby (9) of the building (1).(b) calculating an initial optimal zone boundary value mainly on the basis of traffic statistics and existing transportation capacity.(c) effecting transition of elevator operation to sub-zoning during upward peak traffic.(d) re-calculating the optimal zone boundary value mainly on the basis of short-term traffic statistics, the number of people in the elevator lobby and the available transportation capacity.(e) sensing the need for change in the zone boundary and effecting the desired change as calculated in section (d).(f) cancelling the sub-zoning upon completion of the upward peak passenger period or when the volume of upward traffic has fallen below a predetermined limit.
摘要:
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.
摘要:
A control apparatus for elevators in which one cycle of a fluctuating demand is divided into a plurality of sections, the demand in each section or a service condition value of the elevators for the demand is measured, the demand or the service condition value of the corresponding section is estimated from the measured value, the estimated value is compared with a measured value obtained anew, so that when both the values have not been decided to differ greatly as the result of the comparison, cages may be controlled by the use of an estimative value obtained by considering the measured value obtained anew, whereas when both the values have been decided to differ greatly as the result of the comparison, the cages may be controlled by the use of the estimated value obtained without considering the measured value obtained anew, and measurement value analyzing means is comprised for analyzing the measured values differing greatly from the estimated value, in the same section, so that when a permanent change in the demand or the service condition has been noted as the result of the analysis, the cages may be controlled by the use of the estimated value obtained by considering the measured value differing greatly from the estimated value. Thus, the estimative value is caused to quickly follow up the fluctuation of the demand or the service condition value, and the responsiveness of the cages to the new demand or service condition value can be improved.
摘要:
In an elevator control system comprising a plurality of cars serving a plurality of floors, hall call register means provided on the landing of each floor, cage call register means provided in each car, and means for detecting the number of passenger in each car;The improvement comprising means for forecasting the number of in-cage passengers for every destination floor by allotting the detected number of in-cage passengers to the cage calls, means for detecting the number of waiting passengers provided on the landing of specified floors, means for setting the number of waiting passengers on other than the landing of the specified floors, means for sequentially adding the detected number of prospective passengers waiting on each of the specified floors that have generated the hall calls to the detected number of in-cage passengers, means for sequentially adding the setting of the number of waiting passengers on each of the floors other than the specified floors that have generated the hall calls to the number of detected passengers, means for subtracting the number of forecast in-cage passengers for every destination floor from the detected number of in-cage passengers, means for setting the limit of in-cage passenger number, and means for detecting serviceable floors by comparing the forecast number of in-cage passengers for each floor obtained by the addition and subtraction with the limit of in-cage passenger number.
摘要:
The invention relates to a method of providing a seamless wireless connection in an elevator system of a building. The method comprises receiving an elevator car request from a passenger who is on a source floor, dispatching an elevator car to the source floor in response to the elevator car request, selecting at least one wireless local area network (WLAN) established in the building, and forwarding the selected at least one WLAN via a network node placed in at least one of an elevator hall of the source floor, the dispatched elevator car, or an elevator hall of a destination floor.
摘要:
An elevator trip based on destinations and activity parameters of a user is planned by a system having an elevator controller of an elevator installation, a storage device storing building plan data and a route planning computer. The user's trip inquiry, including a desired destination and a desired activity parameter, is received by the planning computer. Building plan data is read from the storage device by the planning computer. The current location of the user is determined by the planning computer, which calculates at least one route proposal based on the user's location, the destination and the activity parameter. The route proposal is communicated to the user. Upon receipt of a confirmation that the user selected the route proposal, a control signal identifying a boarding floor and a destination floor is transmitted by the planning computer to the elevator controller. The elevator installation is controlled according to the control signal.

The invention relates to a method for allocating elevator calls in an elevator system (10) comprising at least one elevator (12a-12c), which elevator system (10) is controlled by an elevator control (16) comprising a destination call allocation control, wherein passenger IDs are inputted into at least one I/O-device (20) of the elevator system (10), whereafter based on the passenger ID a destination call is issued comprising the floor of the I/O-device (20) as departure floor and a preset or inputted destination floor as destination floor of the elevator call. According to the invention when a new destination call is issued, it is checked whether or not a destination call is still pending under the same passenger ID, and if a destination call of said person is still pending, either the new call or the pending call is cancelled.
