Description

Elevator safety management system and safety management method {Safety Administration System for Elevator and Administration Method Those}

The present invention relates to an elevator safety management system and a safety management method.

Lifts allow people to easily climb up and down relatively high buildings, and are becoming essential building blocks that are indispensable in the modern society.

Since these elevators are occupied by a user in an enclosed space isolated from the outside, it is very important to be able to safely rescue the occupants at a time when a failure of the elevator occurs or a crime inside the elevator.

A common elevator safety management system for occupant safety is an interphone method that connects the elevator interior and the management room with a voice call.

However, the elevator safety management system of interphone boxing is required that the occupant's calmness and the interphone use familiarity, there is a problem in that the rescue request using the interphone is virtually impossible when the occupant is a child or an elderly person.

In particular, when a criminal act such as robbery or assault occurs in an elevator isolated from the outside, the victim is not able to use the interphone user due to a personal threat, and thus the occupant is very dangerous.

As an elevator safety management system for solving such a problem, an image management method for confirming an image of an elevator inside a management room of an image may be used.

The image management method is to install a surveillance camera inside the elevator to always photograph the situation inside the elevator, and to monitor and store the captured image information using the monitor and storage media installed in the management room of the building.

However, in the case of such an image management method, the surveillance camera and the monitor of the management room inside the elevator are always operated even if the user does not board the elevator, which leads to an increase in the elevator management cost due to unnecessary waste of power and loss of storage media. have.

In addition, when the elevator operation is normally performed without an accident for a long time, and the situation where there is no occupant inside the elevator is repeated, the attention of the manager who observes the monitor is likely to be lowered. As a result, when a malfunction of the elevator in a user's boarding state or a criminal activity occurs inside the elevator, the recognition of the internal situation of the elevator due to a decrease in the attention of the manager is not made quickly, thereby preventing passenger safety.

In particular, in the case of a relatively large building or apartment complex in which a plurality of elevators are observed by a plurality of monitors, the manager observes a plurality of monitors, so it is difficult to carefully observe a specific monitor due to gaze dispersion. In particular, as described above, when the normal operation of the elevator and the non-boarding operation are repeated for a considerable period of time, the attention of the manager is greatly reduced, and thus the passenger's safety is not recognized quickly in an emergency such as abnormal operation of the elevator and a crime occurrence. There is a problem that there is no guarantee.

On the other hand, a general elevator management system is a form in which a manager who works in the management room of a building in which a lift is installed recognizes the situation in case of a lift failure or a crime and performs follow-up actions by contacting a lift specialized repair company or a police station.

However, in the conventional elevator management system, as described above, since the emergency situation of the elevator is not recognized quickly by the manager, it is difficult for the manager to appropriately and promptly deal with the accident and follow-up actions (such as contact with the elevator maintenance company and the police station). There is a problem that does not guarantee safety.
