Abstract

An elevator group management device includes: an existing car control device controlling an existing car; a newly-installed car control device controlling a newly-installed car; an evaluation value preparing mechanism preparing evaluation values for the existing car and the newly-installed car; an assignment determining mechanism determining a car assigned to a call based on the prepared evaluation values; an existing car storage beforehand storing information concerning which of the cars is the existing car; and a weight storage beforehand storing a weighting factor for the existing car in the evaluation value. The evaluation value preparing mechanism prepares the evaluation value for the existing car by using the existing car storage information and the weighting factor. The elevator group management device can realize proper car assignment while suppressing occurrence of failure and considering operation efficiency when the existing car and newly-installed car are managed and controlled as one group.

First claim

The invention claimed is:

1. An elevator group management device which manages and controls a plurality of cars including an existing car and a newly-installed car as one group, comprising:
an existing car control device which controls the existing car;
a newly-installed car control device which controls the newly-installed car;
evaluation value preparing means which prepares evaluation values for the existing car and the newly-installed car;
assignment determining means which determines a car assigned to a call from among the plurality of cars on a basis of the evaluation values prepared by the evaluation value preparing means;
existing car storing means which beforehand stores information concerning which of the plurality of cars is the existing car;
weight storing means which beforehand stores a weighting factor for the existing car in the evaluation value; and
failure rate storing means which beforehand stores the failure rate of the existing car for the installation period of the existing car,
wherein the existing car storing means beforehand stores information concerning the production time of each of the existing cars,
the weight storing means beforehand stores the weighting factor for the failure rate, and
the evaluation value preparing means determines the installation period of the existing car from the information concerning the production time of existing car stored by the existing car storing means, obtains the failure rate for the determined installation period of the existing car from the failure rate storing means, obtains the weighting factor for the obtained failure rate from the weight storing means, and prepares the evaluation value for the existing car.

2. The elevator group management device according to claim 1 , wherein
the evaluation value is arrival prediction time to the floor at which a call for each car has been registered,
the assignment determining means determines the car whose arrival prediction time is the shortest to be an assigned car,
the evaluation value preparing means prepares the evaluation value for the existing car by multiplying the arrival prediction time by the weighting factor obtained from the weight storing means, and
the weighting factor for the existing car stored by the weight storing means is set to a value of 1 or larger.

3. The elevator group management device according to claim 1 , further comprising:
wear/deterioration state storing means which beforehand stores the wear/deterioration state of each of the existing cars,
wherein the weight storing means beforehand stores the weighting factor for the wear/deterioration state, and
the evaluation value preparing means obtains the wear/deterioration state of the existing car from the wear/deterioration state storing means, obtains the weight factor for the obtained wear/deterioration state from the weight storing means, and prepares the evaluation value for the existing car.

4. The elevator group management device according to claim 2 , further comprising:
wear/deterioration state storing means which beforehand stores the wear/deterioration state of each of the existing cars,
wherein the weight storing means beforehand stores the weighting factor for the wear/deterioration state, and
the evaluation value preparing means obtains the wear/deterioration state of the existing car from the wear/deterioration state storing means, obtains the weight factor for the obtained wear/deterioration state from the weight storing means, and prepares the evaluation value for the existing car.

5. The elevator group management device according to claim 3 , further comprising:
wear/deterioration state inputting means configured for inputting the wear/deterioration state of each of the existing cars to be stored by the wear/deterioration state storing means.

6. The elevator group management device according to claim 4 , further comprising:
wear/deterioration state inputting means configured for inputting the wear/deterioration state of each of the existing cars to be stored by the wear/deterioration state storing means.

7. The elevator group management device according to claim 1 , further comprising:
modification schedule storing means which beforehand stores the modification schedule of each of the existing cars,
wherein the weight storing means beforehand stores the weighting factor for time period until modification, and
the evaluation value preparing means determines the time period until modification of the existing car from the modification schedule of the existing car stored by the modification schedule storing means, obtains the weighting factor for the determined time period until modification of the existing car from the weight storing means, and prepares the evaluation value for the existing car.

8. The elevator group management device according to claim 2 , further comprising:
modification schedule storing means which beforehand stores the modification schedule of each of the existing cars,
wherein the weight storing means beforehand stores the weighting factor for time period until modification, and
the evaluation value preparing means determines the time period until modification of the existing car from the modification schedule of the existing car stored by the modification schedule storing means, obtains the weighting factor for the determined time period until modification of the existing car from the weight storing means, and prepares the evaluation value for the existing car.

9. The elevator group management device according to claim 1 , further comprising:
paused car determining means which preferentially determines the existing car to be a paused car on a basis of the storage contents of the existing car storing means.

10. The elevator group management device according to claim 2 , further comprising:
paused car determining means which preferentially determines the existing car to be a paused car on a basis of the storage contents of the existing car storing means.

11. The elevator group management device according to claim 1 , further comprising:
paused car determining means which determines the installation period of the existing car from the information concerning the production time of existing car stored by the existing car storing means, obtains the failure rate for the determined installation period of the existing car from the failure rate storing means, and preferentially determines the existing car whose failure rate obtained is relatively high to be a paused car.

12. The elevator group management device according to claim 3 , further comprising:
paused car determining means which obtains the wear/deterioration state of the existing car from the wear/deterioration state storing means, and preferentially determines the existing car whose wear/deterioration state obtained is relatively harsh to be a paused car.

13. The elevator group management device according to claim 4 , further comprising:
paused car determining means which obtains the wear/deterioration state of the existing car from the wear/deterioration state storing means, and preferentially determines the existing car whose wear/deterioration state obtained is relatively harsh to be a paused car.

14. The elevator group management device according to claim 7 , further comprising:
