Elevator security system

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 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.

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 member information through at least one of smart devices coupled to a same home network, upon generation of a predetermined event;
• storing and managing the collected member information of members of a corresponding residence unit;
• receiving passenger information from the server through a communication network;
• comparing the received passenger information and the stored member information to identify members of the corresponding residence unit among the passengers in the elevator;
• and
• transmitting the comparison result to the server,
• 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.
