Abstract

An evacuation strategy support system using an occupant evacuation elevator (OEE) capable of supporting an evacuation strategy so that information on a number of occupants is recognized by real-time occupant monitoring and thus occupants on each floor may use stairs and the occupant evacuation elevator to safely and quickly evacuate when a disaster situation occurs in a skyscraper and thus the occupants use the occupant evacuation elevator to evacuate, capable of monitoring occupant information on each floor in real time and supporting calculation of an evacuation capacity of the occupant evacuation elevator to establish an evacuation strategy to allow safe evacuation and early reaction in an overall skyscraper to be performed, and capable of optimizing the calculation of the evacuation capacity of the occupant evacuation elevator applicable to an initial stage of a design of the skyscraper, and a method thereof are provided.

First claim

What is claimed is:

1. An evacuation strategy support system using an occupant evacuation elevator (OEE) to evacuate in a disaster situation in a skyscraper, comprising:
an occupant monitoring part configured to collect occupant information on a number of the occupants on each floor of the skyscraper to store the occupant information on the number of occupants on each floor in a database, configured to calculate density of the occupants of each floor to perform grouping, and configured to analyze a number of accommodable people and an area of an evacuation safe area to determine whether the evacuation safe area is sufficient so that all the grouped occupants evacuate;
an occupant evacuation elevator specification analyzing part configured to analyze and input a specification of the occupant evacuation elevator in response to the grouped occupants being accommodable in the evacuation safe area;
an evacuation capacity calculating part configured to calculate an operating time of the occupant evacuation elevator of the evacuation safe area and determine whether the occupant evacuation elevator is operable; the evacuation capacity calculating part further configured to review an overload of an evacuation capacity at the evacuation safe area and whether a readjustment and a redesign are necessary, and configured to determine whether the evacuation capacity according to a selection of an evacuation path of the grouped occupants is distributable to calculate a final evacuation capacity of the occupant evacuation elevator; and
an occupant evacuation information providing part linked with a real-time distributed control system to provide occupant evacuation information corresponding to the calculated evacuation capacity of the occupant evacuation elevator,
wherein the evacuation capacity calculating part optimizes evacuation capacity calculation of the occupant evacuation elevator applicable to an initial stage of a design of the skyscraper.

2. The evacuation strategy support system using the occupant evacuation elevator of claim 1 , further comprising a database configured to store the occupant information on the number of occupants collected from the occupant monitoring part, and configured to store occupant evacuation elevator specification data, operating time data according to a general operation method, and National Fire Protection Association (NEPA) data.

3. The evacuation strategy support system using the occupant evacuation elevator of claim 1 , wherein:
the specification of the occupant evacuation elevator includes an elevator capacity, a number of operable elevators, and an operating velocity, which are specifications related to an operation of the occupant evacuation elevator; and
the occupant evacuation elevator specification analyzing part reviews and inputs an operation method of the occupant evacuation elevator.

4. The evacuation strategy support system using the occupant evacuation elevator of claim 1 , wherein the occupant monitoring part includes:
a part for collecting information on the number of occupants of each floor configured to collect the occupant information on the number of occupants on each floor of the skyscraper to store the occupant information on the number of occupants on each floor in the database;
a part for analyzing the density of occupants of each floor configured to calculate density, which is a number of people per area of the occupants of each floor, and to perform grouping so that the density of the occupants corresponds to the number of accommodable people at an evacuation safe floor;
an evacuation safe area analyzing part configured to analyze the number of accommodable people and an area of an evacuation safe area; and
an evacuation safe area accommodation determining part configured to determine whether the evacuation safe area is sufficient so that all the grouped occupants evacuate.

5. The evacuation strategy support system using the occupant evacuation elevator of claim 1 , wherein the evacuation capacity calculating part includes:
an occupant evacuation elevator operation determining part configured to calculate an operating time of the occupant evacuation elevator of the evacuation safe area and determine whether the occupant evacuation elevator is operable;
an evacuation capacity review part of the evacuation safe area configured to review the overload of the evacuation capacity at the evacuation safe area and whether the readjustment and the redesign are necessary in response to the occupant evacuation elevator being operable;
an evacuation capacity distribution determining part configured to determine whether the evacuation capacity according to the selection of the evacuation path of the grouped occupants is distributable; and
a final evacuation capacity calculating part configured to calculate the final evacuation capacity of the occupant evacuation elevator.

6. The evacuation strategy support system using the occupant evacuation elevator of claim 1 , wherein the real-time distributed control system selectively extracts a disaster/catastrophe situation and corresponding information of the skyscraper to quickly share to a location at which information is necessary, as a cyber physical system (CPS) linked with the evacuation capacity calculating part to provide evacuation situation information.

7. An evacuation strategy support method using an occupant evacuation elevator (OEE) to evacuate in a disaster situation which occurs in a skyscraper, comprising:
a) collecting occupant information on a number of occupants on each floor of the skyscraper and storing the occupant information on the number of occupants on each floor in a database;
b) calculating density of the occupants of each floor to perform grouping;
c) analyzing a number of accommodable people and an area of an evacuation safe area;
d) determining whether the evacuation safe area is sufficient so that all the grouped occupants evacuate;
e) analyzing and inputting a specification of the occupant evacuation elevator in response to the grouped occupants being accommodable in the evacuation safe area;
f) determining whether the occupant evacuation elevator of the evacuation safe area is operable;
g) reviewing an overload of an evacuation capacity at the evacuation safe area and whether a readjustment and a redesign are necessary in response to the occupant evacuation elevator being operable;
h) determining whether the evacuation capacity according to a selection of an evacuation path of the grouped occupants is distributable;
i) calculating a final evacuation capacity of the occupant evacuation elevator; and
j) providing occupant evacuation information linked with a real-time distributed control system to correspond to the calculated evacuation capacity of the occupant evacuation elevator,
wherein evacuation capacity calculation of the occupant evacuation elevator applicable to an initial stage of a design of the skyscraper is optimized.

8. The evacuation strategy support method using the occupant evacuation elevator of claim 7 , wherein the database in the operation a) stores the collected occupant information on the number of occupants, and stores occupant evacuation elevator specification data, operating time data according to a general operation method, and National Fire Protection Association (NEPA) data.

9. The evacuation strategy support method using the occupant evacuation elevator of claim 7 , wherein:
the specification of the occupant evacuation elevator in the operation e) includes an elevator capacity, the number of operable elevators, and an operating velocity which are specifications related to an operation of the occupant evacuation elevator; and
an operation method of the occupant evacuation el
