Abstract:
The present invention is directed to determining an arrival time for each of the passengers boarding an elevator car. Where the elevator car stops at a floor in response to a hall call request, the arrival time of the passengers which boarded the elevator car is preferably determined based the time period between when the hall call was registered and when the elevator car door closed. Where the elevator car stops at a floor in response to a car call registered within the elevator, the arrival time of the passengers which boarded the elevator car is preferably determined based on the time period between when the elevator stopped at the floor and when the elevator car door closed. Alternatively, the time period between when the elevator car door opened and when the elevator car door closed can be used. In the preferred embodiment, the first passenger is assumed to have an arrival time corresponding to the beginning of the time period. If more than one passenger boarded the elevator, the passengers are assumed to have arrived in a distributed fashion over this time period.
Abstract:
Elevator control software uses a signal from a passenger weight sensor and observed weight fuzzy logic sets to provide a fuzzy logic set indicative of the number of passengers in an elevator car. Optionally, the fuzzy set is defuzzified to produce a single crisp value indicative of the number of car passengers. Also, a table having indices corresponding to passenger weights and entries corresponding to the number of passengers in an elevator can be constructed using the plurality of observed weight fuzzy sets.
Abstract:
An uncertainty filter is provided with input data which is indicative of a fuzzy logic set having basis elements corresponding to elevator cars of an elevator system having degrees of membership associated therewith corresponding to the utility (suitability) of assigning the associated car to service a hall call. The uncertainty filter chooses a car corresponding to the term from the set having the highest degree of membership. The choice can be delayed until; a predetermined amount of time has passed; the degree of membership exceeds a predetermined amount; or the degree of certainty (the degree of membership of the chosen car over the sum of degrees of membership of the other cars) is more than a predetermined amount; or until either the degree of membership or the degree of certainty meets a value which varies as a function of time from when a hall call was registered.
Abstract:
The invention relates to call registration wherein of a plurality of elevators an elevator which a user (passenger) wants to ride is called to the elevator hall of the user. A display is provided at an elevator hall for users. When a user depresses a hall calling button, a group supervisory controller determines and selects a suitable elevator, and causes the condition of the elevator to be displayed on the display in the form of sentences or the like. If the user is satisfied with the selected elevator, the hall calling button is not actuated again. If the user is dissatisfied with the selected elevator, the hall calling button is depressed again so that the controller selects another elevator for service to the user.
Abstract:
An apparatus for statistically processing elevator traffic information by statistically processing traffic information on each building floor in each of a number of time zones of a day to generate group control information, comprising a first statistical data generator device responsive to the traffic information on each floor for issuing a total value of the traffic information as a statistical value, a second statistical data generator device for issuing as a statistical value the ratio of the traffic information on each floor to the absolute value of traffic information, and a control converter device for converting the statistical values from the first and second statistical data generator devices into the group control information.
Abstract:
A supervisory apparatus for elevators wherein cages are respectively caused to disperse and wait at predetermined floors during an inactive elevator operation during which a demand for the cages has decreased; the demand magnitudes of the cages in each of a predetermined number of time zones into which one day is divided, future demand magnitudes are estimated for each time zone on the basis of the measured values, and a suitable number of floors are allotted to each cage on the basis of the estimated demand magnitudes so that the respective cages may take charges of equal demand magnitudes during the inactive elevator operation. Further, the waiting floor of each cage is determined at that floor of the allotted floors at which an expected value of a period of time required for responding to a next occurring hall call becomes the smallest.
