Abstract

An elevator security procedure is performed according to a security level of an elevator of a building including a plurality of residence units through an elevator security system. The elevator security system includes home gateways respectively installed at the plurality of residence units and a server coupled to the home gateways. The server may analyze a comparison result of passenger information of passengers in the elevator and member information of members of residence units associated with floors selected by the passengers in the elevator. The server may determine a security level of the elevator based on the analysis result. The server may perform a security procedure designated for the determined security level by controlling at least one of constituent elements of the elevator and smart devices coupled to the at least one of home gateways.

First claim

What is claimed is:

1. A method of performing an elevator security procedure according to a security level of an elevator of a building including a plurality of residence units through an elevator security system including home gateways respectively installed at the plurality of residence units and a server coupled to the home gateways, the method comprising:
analyzing a comparison result of passenger information of passengers in the elevator and member information of members of residence units associated with floors selected by the passengers in the elevator;
determining a security level of the elevator based on the analysis result; and
performing a security procedure designated for the determined security level by controlling at least one of constituent elements of the elevator and smart devices coupled to the at least one of home gateways,
wherein the method comprises:
analyzing the passenger information including a monitoring result of monitoring activities of the passengers in the elevator; and
determining whether an abnormal event occurs in the elevator based on the analysis result and
wherein the abnormal event is determined to occur when the monitoring result includes information on a measured pressure level higher than a predetermined pressure level, when the monitoring result includes information on a measured sound level higher than a predetermined sound level, when the monitoring result includes information on an identified stranger not getting off the elevator on a floor selected by the identified stranger, and when the monitoring result includes information on the identified stranger included in a wanted person list.

2. The method of claim 1 , prior to the analyzing, further comprising:
receiving the passenger information from the elevator through a communication network; and
determining residence units associated with floors selected by passengers in the elevator based on the passenger information.

3. The method of claim 2 , comprising:
transmitting the received passenger information to home gateways of the determined residence units through a communication network;
receiving the comparison result from the home gateways of the determined residence units through the communication network; and
determining whether the passengers of the elevator are the members of the residence units based on the received comparison result.

4. The method of claim 2 , comprising:
transmitting a request home gateways of the determined residence units to provide member information;
receiving the member information from the home gateways of the determined residence units; and
determining whether the passengers of the elevator are the members of the residence units by comparing the passenger information and the member information.

5. The method of claim 1 , wherein:
the passenger information includes a shoe size, a shoe shape, a shoe outsole pattern, a weight, a moving direction, a selected floor to travel, a footstep pattern, an activity, a sound, of each passenger in the elevator; and
the passenger information is sensed and collected by a plurality of sensors of the elevator.

6. The method of claim 1 , wherein:
the member information includes identification, a shoe size, a shoe shape, a shoe outsole pattern, a weight, a height, an eye color, a hair color, a footstep pattern, a voice tone, a time of come-in, a time of go-out, a current in/out status, a coming home pattern, and a going out pattern of each member; and
the member information of each member of a respective residence unit is sensed and collected by a plurality of smart devices coupled to the home gateways.

7. The method of claim 1 , wherein the analyzing a comparison result comprises:
identifying a stranger among the passengers in the elevator based on the comparison result.

8. The method of claim 1 , wherein the determining a security level comprises:
determining a security level as a normal level when all of the passengers is identified as members of the associated residence units based on the analysis result;
determining a security level as an intermediate level when at least one of the passengers is identified as a stranger based on the analysis result;
determining a security level as a high level when an abnormal event is occurring in the elevator by a result of analyzing the passenger information; and
performing the security procedure designated for the determined one among the normal level, the intermediate level, and the high level.

9. The method of claim 1 , wherein the performing a security procedure comprises, when the determined security level is a normal level:
controlling home gateways of residence units associated with the passengers to output an informing message at the associated residence units and controlling at least one of constituent elements of the elevator to transmit captured images to the home gateways of the associated residence units,
wherein the information message is one of a voice message and a text message that informs of related members that a passenger is in an elevator.

10. The method of claim 1 , wherein the performing a security procedure comprises, when the determined security level is an intermediate level;
controlling at least one constituent element to output a warning message inside the elevator 100 ;
transmitting an informing message with information on a detected stranger to home gateways of residence unites associated with the passengers in the elevator;
transmitting captured images to the home gateways of the associated residence units.

11. The method of claim 1 , wherein the performing a security procedure comprises, when the determined security level is a high level;
sounding an alarm and outputting a warning message through at least one constituent element inside elevator;
transmitting an informing message with information on identified strangers to home gateways of residence units associated with the passengers in the elevator;
transmitting captured images to the home gateways of the associated residence units; and
controlling the elevator to stop and/or to open or close a door of the elevator.

12. The method of claim 11 , wherein the performing a security procedure further comprises:
transmitting an informing message with information on the identified strangers to at least one of a related security office and a related police station; and
transmitting captured images in real time to the at least one of the security office and the police station.

13. A method of performing an elevator security procedure according to a security level of an elevator of a building including a plurality of residence units through an elevator security system including home gateways respectively installed at the plurality of residence units and a server coupled to the home gateways, the method comprising:
collecting passenger information upon generation of a predetermined event;
transmitting the collected passenger information to the server through a communication network;
receiving a control signal from the server; and
controlling constituent elements based on the control signal,
wherein the method comprises:
analyzing the collected passenger information including a monitoring result of monitoring activities of the passengers in the elevator; and
determining whether an abnormal event occurs in the elevator based on the analysis result and
wherein the abnormal event is determined to occur when the monitoring result includes information on a measured pressure level higher than a predetermined pressure level, when the monitoring result includes information on a measured sound level higher than a predetermined sound
