Description

Elevator safety management terminal with elevator emergency contact system and safety management application installed {SYSTEM FOR ELEVATOR EMERGENCY COMMUNICATION AND DEVICE FOR ELEVATOR SAFETY MANAGEMENT}

It relates to an emergency contact system and an elevator safety management terminal for preventing safety accidents in the event of an elevator emergency situation, and specifically, to an emergency contact system through a smart terminal provided inside the elevator and an elevator safety management application installed in the smart terminal.

Unless otherwise indicated herein, the content described in this section is not prior art to the claims of this application, and inclusion in this section is not admitted to be prior art.

An elevator is a mechanical device with an elevator car installed in a high-rise building and automatically moves people between floors and floors of a building. In general, elevators consist of a cage that carries people or cargo and a hoisting machine that operates the cage up and down, a guide rail, a counterweight and wire rope to reduce the load of the hoisting machine, and a power supply device that supplies driving voltage to the hoisting machine. do. In addition, an operation button and an emergency contact button are provided in the elevator to control the elevator such as raising and lowering the elevator and opening and closing the door. Such an operation button is generally a push-type button that is operated by a user's hand, and is implemented in various forms such as protruding or buried than a plate on a wall on which the operation button is installed.

Among these operation buttons, an emergency call button for making a phone call with a manager when a user is trapped in the elevator due to an accident or an emergency situation occurs during use of the elevator is separately provided. The emergency call button is an essential device for preventing personal accidents and safety in the elevator, but in case an elevator safety accident actually occurs, it is often not possible to connect to the manager even if the emergency call button is pressed. Since the conventional emergency call button is connected to the manager and the management server in case of an emergency situation through wired communication method, the emergency call button may not operate unless a power outage and voltage supply throughout the building are made.

In addition, a lot of time and cost are required to check the conventional wired emergency call button during regular elevator inspection. This is because the conventional emergency call button is a wired communication method, so all emergency call buttons must be managed and checked. In addition, the emergency call button of the conventional elevator should be used only in an emergency or emergency situation, but as it is arranged with a general operation button without any special protection means, the button is pressed due to a mischief of children or carelessness, or a handrail. There is a problem in that normal management is not performed properly, such as the user leaning on the body or pressing a button indirectly by an elbow.
