Elevator group management and control device

Abstract

An elevator management and control device for selecting an elevator car when a landing call registration device is away from a landing, where the selection is made by taking user's walk time and the number of floors the elevator serves into account. The elevator management and control device has a walk time estimation means (9) for estimating the time required for a passenger to reach a landing, aprediction and calculation means (10) for predicting and calculating a time in which each elevator car (2) can reach the landing, a waiting time conversion means (11) for converting the difference between the predicted time before arrival of the car (2) that is predicted and calculated by the prediction and calculation means (10) and the estimated walk time into real waiting time or loss time, anevaluation value calculation means (12) for calculating an evaluation value increasing with an increase in real waiting time or loss time, an allocation means (13) for determining a car, as an allocated car, whose evaluation value calculated by the evaluation value calculation means (12) is minimum, an operation control means (15) for instructing the allocated car to move to the floor for which the call is registered, and a door opening / closing means (14) not opening a door (2) of the allocated car until the estimated walk time has passed after the door is opened.

Description

technical field [0001] The present invention relates to an elevator group management control device that efficiently manages and controls the transportation of a plurality of elevators. Background technique [0002] In conventional elevator group supervisory control devices, there is call allocation control as one of group supervisory controls performed when a plurality of elevators are installed in parallel. In the call allocation control, when a landing call is registered, the car that should serve the landing call is selected and allocated immediately, thereby determining the allocated car that should respond. By appropriately performing such call allocation, the transportation efficiency of a plurality of elevators installed in a building or the like can be improved. [0003] In addition, there is a system in which a device capable of registering a hall call is installed at a certain distance from a hall and registers a hall call, for example, an example in which a devi...

Problems solved by technology

Therefore, in a high-rise building served by multiple cars, contrary to the case where the elevator near the call registration floor arrives and waits with the door open, the elevator that is arbitrarily selected exists due to calls from other floors. The case where the arrival time of the car is significantly delayed compared with the walking time to reach the elevator
