Elevator group management device and elevator group management method

Abstract

It is intended to provide an elevator group management apparatus having high versatility and a stably-large electric-power-saving effect. An operation status measurement unit 109 measures a frequency (e.g., number of running times) of power operation of an entire elevator group, and a frequency (e.g., number of running times) of regeneration operation of the entire elevator group. The operation status measurement unit 109 calculates a ratio between the frequency of the regeneration operation and the frequency of the power operation. When the ratio between the frequency of the regeneration operation and the frequency of the power operation is greater than a predetermined value (e.g., 2.0), an assigned car selection unit 106 selects an elevator (i.e., a car 103) from the elevator group according to a preset priority order. A car halt unit 110 halts the operation of the car 103 selected by the assigned car selection unit 106.

Description

technical field [0001] The present invention relates to an elevator group management device and an elevator group management method. Background technique [0002] In recent years, a group management apparatus for controlling a plurality of elevators can realize arithmetic processing of a large amount of information and high-level control by using a microcomputer. [0003] In recent years, the realization of eco-friendly products has been increasingly demanded for various industrial products including elevators. In a large-scale high-rise building in which dozens of elevators are installed, it is no longer possible to ignore the situation of electric power consumption due to travel of elevators. [0004] Several proposals have been made in the past to achieve energy saving in a group management device. For example, Patent Document 1 proposes a method in which the number of people in a building is detected, compared with a predetermined number of registered people, and the n...

AI Technical Summary

Problems solved by technology

[0009] The existing technology, for example, uses a unit different from the group management device that detects the number of people in the building and predetermines the number of registered people, so the versatility is relatively low

In addition, the existing technology simply controls the timing of turning on the lighting in the car, so the energy saving effect is relatively low

In addition, the number of people who will get into the car is predicted every time a hall call occurs, and the operation of the car is controlled according to the predicted number of people, so the energy-saving effect is limited by the prediction accuracy

[0010] In addition, in the prior art, for example, there is no power-saving scheme corresponding to seasons such as summer and winter, which consume a lot of power.

In addition, there is no proposal for the choice of a resting car that considers the user's convenience of use.

And, although some schemes give priority to the landing call that makes the car run in the direction of regeneration, it cannot guarantee that the car will run in the direction of regeneration whenever a landing call occurs, and for example, it does not consider From the perspective of a longer period of time, the overall increase in the proportion of the car running in the direction of regeneration
