Abstract

The present invention relates to an IoT-based autonomous guide system and method for an elevator during unawareness. The present invention is configured to mutually and organically operate an elevator system, an intelligent IoT device unit, and a cloud server. Thus, elevator passengers having much lower cognitive ability as well as normal persons can receive a safer and more convenient service. An organic connection between objects, between an object and a mobile, and between a mobile and a person allows a driving state of an elevator to be monitored, diagnosed, and controlled through two-way communications in real time. When an accident occurs during driving of the elevator, a description of the accident and advice thereon are provided to the passengers or latent users through digital signage or mobile devices. Accidents can be autonomously dealt with while the situation of the accident is transmitted to a registered remote place and an emergency response system such as passenger rescue can be quickly directed. The safety of the passenger and maintenance of the elevator can be achieved.

[0001] The present invention relates to an elevator, an elevator, an elevator,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator intelligent IoT device for safety and maintenance of an elevator moving vertically and horizontally to transport a passenger, a vehicle or a cargo, and more particularly, Analyze, and store the information to the cloud operation center to distribute the situation to the relevant agencies (eg, management office, elevator manufacturer / maintenance company, 119 control room, police station, etc.) It provides smart services according to the situation through broadcasting, digital signage and mobile devices. Especially, in case of system malfunction, obstacle or accident, the system can be used for general passengers as well as disabled persons, seniors, pregnant women, To recognize and judge the situation and to explain safety and related situation and cope Providing guidance services, in conjunction with the IoT real-time big data analysis linked to the site, in conjunction with the cloud center and external system providing AI (Intelligent AI) functions, and elevator life safety and maintenance during the lifetime of the elevator And more particularly, to an elevator object-based on-site self-guided information system and method for providing a proactive maintenance system for the Internet.

In general, control systems related to elevator operation continue to pursue better service to passengers in various buildings. In addition to ordinary passengers, the control system has a remarkable ability to recognize various types of users, such as disabled persons, infants, pregnant women, For those who fall, there is also a need to provide services that are practically helpful by an active and autonomous system that is susceptible to potential safety hazards.

However, the control system of the conventional elevator is limited in service by the local on-site unit operation as in the appended Fig. 1, and the service access to the elderly, pregnant or infant passengers is restricted and the difficulty of coping with unexpected accidents There is a problem that it is difficult for the manager (engineer) to take immediate action in case of a failure or a failure.

In other words, since the conventional elevator control system is installed in the field and operated independently, it is difficult to know the operating state of the elevator, so that the manager has to constantly visit and manage the conventional elevator control system. It is difficult to respond in real time.

First, there is a concern that the leveling error between the floor and the corridor of the aisle may expose children to the accident, as well as the general public, the elderly, and pregnant women.

Second, malfunctions due to faults in car doors and corridor doors, or problems with opening and closing, may put passengers at risk.

Third, the risk of accidents is high due to overspeed issues caused by malfunction of the elevator control system.

Fourth, a dangerous situation can occur such as falling into the shaft due to a major accident such as power outage or confiscation accident.

Fifth, if repair and inspection are not carried out at appropriate time, malfunctions often lead to accidents.

On the other hand, conventionally, there has been a difficulty in maintaining and managing elevators of various manufacturers / vendors in a building.

In other words, it is difficult to perform integrated monitoring and diagnostic control with a unique interface protocol for each manufacturer.

In addition, conventionally, there is a considerable difficulty in real-time monitoring of a failure or a failure state of an elevator, and it is difficult to cope with customer demand in real time due to difficulty of real-time inventory management of elevator maintenance parts. Response, and supply chain management (SCM), warehouse management, and so on.

Accordingly, the elevator system for minimizing the downtime of the elevator, reducing the number of defects, managing the detailed information, and providing the seamless service can be safely and intelligently connected to the user The necessity of gateway devices, the necessity of applying the latest technologies such as ICBMA (Internet, Cloud, Bigdata, Mobile, Artificial Intelligent) which is represented by the 4th industrial revolution, the necessity of prediction system against potential failure or obstacle of elevator, There is a growing need for a variety of convenient service requirements for elevator users through mobile and digital signage.
