Description

Technical Field

[0001] The present invention relates to an elevator control system, and more specifically, to a GIS-based elevator control system using a digital signage terminal for elevators.

Background Art

[0002] Elevators have become an indispensable means of transportation in modern society, but the response system to safety accidents and emergencies is still insufficient. In particular, the absence of an appropriate response system to extraordinary situations such as falls, violence, and fires that can occur inside elevators has emerged as a major safety issue. In such a situation, existing emergency bell-based systems rely on physical button operations and have limitations in immediate response.

[0003] Existing elevator control systems are mainly operated in a way that a person directly stays to monitor problems and respond after receiving reports. Such a method is limited in perceiving and dealing with problems in real time. In particular, the response speed becomes slow during time periods when no one is staying. Also, the current system may become useless in situations where users cannot recognize or use the emergency button.

[0004] The accessibility of elevator systems for socially vulnerable people, especially those with visual and hearing impairments, is also at a low level. Since existing systems rely only on voice and text guidance, it is difficult for users with various types of disabilities to appropriately respond in emergency situations. Therefore, there is a need to strengthen information transmission and interaction with users in extraordinary situations.

[0005] Existing elevator maintenance and management systems are carried out in a way that responds after a failure occurs, and lack the function of preventing or precluding accidents. In particular, since information transmission between the management entity and the maintenance provider is not performed in real time, there is a problem that the rescue time is delayed.

[0006] Currently, signage systems inside elevators are primarily limited to advertising and providing basic safety information. The utilization of internal displays in elevators during emergencies is low, highlighting the need for an integrated platform that can effectively support situation dissemination and rescue requests.

[0008] The object of the present invention is to provide a GIS-based elevator control system that utilizes a digital signage terminal for elevators. [Means for solving the problem]

[0009] The elevator control system based on a GIS that utilizes a digital signage terminal for elevators according to the above-described objectives of the present invention may be configured to include a digital signage terminal for elevators that conducts video calls between passengers and control personnel when an abnormal situation occurs, and a control center terminal that conducts video calls between passengers inside the elevator and the control personnel.

[0010] Here, the abnormal situation may be configured to include a fire, smoke, power outage, the passenger collapsing, acts of violence, and acts of robbery inside the elevator.

[0011] Furthermore, the digital signage terminal for elevators may be configured to output elevator safety accident content and advertising content. [Effects of the Invention]

[0012] According to the GIS-based elevator control system using the aforementioned digital signage terminal for elevators, various IoT-based sensors such as IoT vibration sensors, sound sensors, and acceleration sensors are utilized to continuously monitor the status of the elevator drive system. By analyzing the data in real time, malfunctions and abnormal conditions can be detected early, which helps prevent accidents and maximizes maintenance efficiency.

[0013] Furthermore, the digital signage terminals for elevators automatically recognize abnormal situations and enable immediate action through linkage with control center terminals and on-site personnel terminals. Real-time consultation and rescue support are provided through video calls with control personnel, and the system also allows visually and hearing impaired individuals to safely use the service through sign language avatars and braille tactile displays.

[0053] Here, the abnormal situation may be configured to include, for example, a fire inside the elevator, smoke, a power outage, the passenger collapsing, acts of violence, or acts of robbery.

[0054] At this time, the elevator safety accident content output control module 507 can be controlled to select and output elevator safety accident content corresponding to the abnormal situation automatically recognized by the abnormal situation automatic recognition module 511 using the elevator safety accident content storage module 501.

It may also be configured to feed the analysis results back to the CMS server 30.

[0065] Here, the advertising content storage control module 503 may be configured to select and request advertising content to be stored in the advertising content storage module 502 on the CMS server 30 based on the passengers cumulatively analyzed by the passenger cumulative analysis module 517 and the advertising interest level of each passenger analyzed by the advertising interest level analysis module 519, and to receive the requested advertising content and store it in the advertising content storage module 502.

[0066] On the other hand, if the passenger's gaze remains fixed for less than a predetermined time based on the real-time monitoring results of the passenger gaze monitoring module 518, the advertising content output control module 508 can stop outputting the relevant advertising content and control the advertising content storage module 502 to re-select and output advertising content stored in real time.

[0069] The IoT sensor value analysis module 521 for each elevator component may be configured to work in conjunction with the control values ​​of the elevator drive controller 20 and analyze vibration, sound, and acceleration stored in the IoT sensor value accumulation storage module 520 for each elevator component in real time. If the vibration, sound, and acceleration linked to the previously accumulated control values ​​change significantly beyond a predetermined standard, it can be analyzed that the elevator component in question is malfunctioning or needs to be replaced.

[0070] The elevator component-specific failure / replacement notification transmission module 522 may be configured to generate elevator component-specific failure / replacement notifications based on the analysis results of the elevator component-specific IoT sensor value analysis module 521 and transmit them in real time to the GIS-based elevator control server 700.

[0071] The destination floor automatic drive module (not shown) may be configured to automatically drive the elevator to the destination floor by comparing the destination floor with the most frequently recorded destination floor with the current floor, when the passenger QR code is recognized by the passenger QR code recognition module 505. For example, if a passenger mainly uses the 1st and 11th floors, the elevator can automatically drive to the 11th floor if the current floor is the 1st floor, and vice versa if the current floor is the 11th floor. This has the advantage of being able to drive the elevator without touching any buttons.

[0072] The control center terminal 600 may be configured to facilitate video calls between passengers in the elevator and the air traffic controller.

[0081] The elevator component-specific failure / replacement notification receiving module 705 may be configured to receive elevator component-specific failure / replacement notifications in real time from the elevator component-specific failure / replacement notification transmitting module 522.

[0082] The elevator component-specific fault / replacement inspection command generation module 706 may be configured to generate elevator component-specific fault / replacement inspection commands in real time in response to elevator component-specific fault / replacement notifications received in real time from the elevator component-specific fault / replacement notification receiving module 705.
