System for measuring interfloor traffic for group control of elevator cars

Claim 1

A system comprising: position detecting means (5) for detecting a position of an elevator car (1); passenger number detecting means (7) for detecting an outgoing passenger number and an incoming passenger number at each of floors at which said elevator car stops; car call registering means (6) for registering car calls for destination floors which are made by incoming passengers at each of the floors at which said elevator car stops; a clock device (9); hall call registering means for registering a hall call at each service floor; interfloor traffic measuring means (4) for distributing passengers whose destination floors cannot be determined, the number of which is determined by the incoming or outgoing passenger number and the number of the registered car calls, to each of origin-destination floor pairs using empiricial probability weights which are derived from previous traffic measurements, and estimating the number of passengers for each of the origin-destination floor pairs in accordance with passengers whose destination floors can be determined by the incoming passenger number and the number of the registered car calls, and the distributed passengers; recording means (8) for recording the measured interfloor traffic for each of origin-destination floor pairs and for each of predetermined time conditions; and predicting means (4) responsive to the measured traffic for predicting average traffic per unit time for each of the origin-destination floor pairs, arrival time of said elevator car at a floor at which a hall call is registered, and destination floors of incoming passengers at the hall-call registered floor in accordance with the predicted arrival time of said elevator car and the predicted average traffic.

Claim 2

A system comprising: position detecting means (5) for detecting a position of an elevator car (1); passenger number detecting means (7) for detecting an outgoing passenger number and an incoming passenger number at each of floors at which said elevator car stops; car call registering means (6) for registering car calls for destination floors which are made by incoming passengers at each of the floors at which said elevator car stops; a clock device (9); hall call registering means for registering a hall call at each service floor; interfloor traffic measuring means (4) for distributing passengers whose destination floors cannot be determined, the number of which is determined by the incoming or outgoing passenger number and the number of the registered car calls, to each of origin-destination floor pairs using empiricial probability weights which are derived from previous traffic measurements, and estimating the number of passengers for each of the origin-destination floor pairs in accordance with passengers whose destination floors can be determined by the incoming passenger number and the number of the registered car calls, and the distributed passengers; recording means (8) for recording the measured interfloor traffic for each of origin-destination floor pairs and for each of predetermined time conditions; and predicting means (4) responsive to the measured traffic for predicting average traffic per unit time for each of the origin-destination floor pairs, arrival time of said elevator car at a floor at which a hall call is registered, and destination floors of incoming passengers at the hall-call registered floor in accordance with the predicted arrival time of said elevator car and the predicted average traffic.

Claim 8

A method of measuring interfloor traffic of passengers utilizing an elevator car comprising the steps of: detecting a position of said elevator car; detecting an incoming passenger number and an outgoing passenger number at each of floors at which said elevator can stops; registering car calls for destination floors specified by incoming passengers at each of the floors at which said elevator car stops; registering a hall call at each service floor; distributing passengers whose destination floors cannot be determined, the number of which is determined by the incoming or outgoing passenger number and the number of the registered hall calls, to each of origin-destination floor pairs using empiricial probability weights which are derived from previous traffic measurements; and estimating the number of passengers for each of the origin-destination floor pairs in accordance with passengers whose destination floor can be determined by the incoming passenger number and the car call registration number, and the distributed passengers.

Claim 9

A method of measuring interfloor traffic of passengers utilizing an elevator car comprising the steps of: detecting a position of said elevator car; detecting an incoming passenger number and an outgoing passenger number at each of floors at which said elevator can stops; registering car calls for destination floors specified by incoming passengers at each of the floors at which said elevator car stops; registering a hall call at each service floor; distributing passengers whose destination floors cannot be determined, the number of which is determined by the incoming or outgoing passenger number and the number of the registered hall calls, to each of origin-destination floor pairs using empiricial probability weights which are derived from previous traffic measurements; and estimating the number of passengers for each of the origin-destination floor pairs in accordance with passengers whose destination floor can be determined by the incoming passenger number and the car call registration number, and the distributed passengers.

Claim 10

A method of predicting passenger traffic demand of for an elevator car comprising the steps of: detecting a position of said elevator car; detecting an incoming passenger number and an outgoing passenger number at each of floors at which said elevator car stops; registering car calls for destination floors specified by incoming passengers at each of the floors at which said elevator car stops; measuring traffic of passengers utilizing the elevator car between origin-destination floor pairs in response to a detected position of said elevator car, detected passenger number, and registered car calls to predict an average traffic per unit time for each of the origin-destination floor pairs; predicting arrival time of said elevator car at a floor at which a hall call is registered; and predicting destination floors of incoming passengers at the hall-call registered floor in accordance with the predicted arrival time and the predicted average traffic.

Claim 11

A method of predicting passenger traffic demand of for an elevator car comprising the steps of: detecting a position of said elevator car; detecting an incoming passenger number and an outgoing passenger number at each of floors at which said elevator car stops; registering car calls for destination floors specified by incoming passengers at each of the floors at which said elevator car stops; measuring traffic of passengers utilizing the elevator car between origin-destination floor pairs in response to a detected position of said elevator car, detected passenger number, and registered car calls to predict an average traffic per unit time for each of the origin-destination floor pairs; predicting arrival time of said elevator car at a floor at which a hall call is registered; and predicting destination floors of incoming passengers at the hall-call registered floor in accordance with the predicted arrival time and the predicted average traffic.
