It's being a trend that contemporary buildings are getting higher. And in line with this, we suggest the smart elevator operation management mobile application which is designed using clustering techniques to improve user's elevator access control and convenience. This clustering technique using the elevator's calling data make it possible to find its best position, and know the state of it using a smart phone as well. With this, not only the users' waiting time can be decreased, but also their convenience can be improved with the remote control system that got efficient a lot.

Recently, most of people wants to have smart life for themselves like smart phones. In this paper, we propose the smart elevator based on the laser screen, speakers and air fresheners. Using this elevator, we could enjoy the various screen inside, and we could keep contacting with manager for wifi in the emergency situation. Also, the elevator could be operated with user's motion for Kinect. Finally, we did the survey for understanding preference of smart elevator. The grops are elevator manufacturing company, elevator distribution corporation and consumers, each group have 200 people.

From Korea Elevator Safety Institute's report, the major accident factor of elevator is user's mistake, 60%. It means that the necessity of simple monitoring system. In this paper, we explain the standard of elevator safety check and the rate of accidents, then compare with old elevator managing system and new elevator managing system based on IOT technology. Also, we explain the reliability statistics of smart managing system based on expert's decision. Finally, we propose the smart managing system as the alternative method for decreasing the accident factor of elevator.

In a modern smart building, sensors can detect various physical conditions, such as temperature, humidity, sound, motion, and light, which can be used in medical services and security, and for energy savings. This paper presents an efficient elevator scheduling system that utilizes smart sensor technologies with radio-frequency identification, video, and floor sensors to detect the arrival of elevator users in advance. The detected information is then delivered to the elevator scheduling system via building networks. By using this information, the proposed system makes a reservation call for efficient control of the elevator's direction and time. Experiments under a spectrum of traffic conditions show that the proposed system performs better than a legacy system with respect to average wait time, maximum wait time, and energy consumption.

In this paper, a smart elevator system was studied using real-time object detection technology based on YOLO(You only look once)v5. When an external elevator button is pressed, the YOLOv5 model analyzes the camera video to determine whether there are people waiting, and if it determines that there are no people waiting, the button is automatically canceled. The study introduces an effective method of implementing object detection and communication technology through YOLOv5 and MQTT (Message Queuing Telemetry Transport) used in the Internet of Things. And using this, we implemented a smart elevator system that determines in real time whether there are people waiting. The proposed system can play the role of CCTV (closed-circuit television) while reducing unnecessary power consumption. Therefore, the proposed smart elevator system is expected to contribute to safety and security issues.

Recently, It has enlarged various service requirements for the market of elevator with the environment of IT convergency. In this paper, we propose the information and control system of elevator based on media streaming service that is extended from the existing control system of an elevator. There is the service environments based on Internet for architecture of information communication in the framework of the suggested streaming service. We use this framework to operate and integrate the various services of elevator system. And also, we so apply to the user requirements easily that we can construct the smart elevator environment by convergence home network and various electronic devices based on IT.

Smart work can classify three types. First, mobile office equipped with a portable computer and connect to the company servers and Intranet via mobile phones. Second, home working using video conference system. Third, smart work center. Smart work has enabled us to work efficiently, to work anytime and to work anywhere, beyond conventional office working. This paper presents development processes of a smart work for After Service Business, especially, for the elevator industry. we called implemented mobile office system "A/S work". A/S work using mobile devices has some advantages as compared with previous system. 1) Before/After photo management function 2) Assessment process of customer satisfaction 3) The work history management app. 4) The inquiry and confirmation function to current status of all workers 5) The group SMS function sending selected workers. 'M' elevator company has used A/S work as efficient smart work system.

In this paper, we proposed an efficient method for implementing a voice recognition elevator. Unlike the existing ones, the proposed system is based on the bluetooth communication and smartphones equipped with the google speech recognition software, which makes it possible that the speech recognition capability can be added to the previously installed elevators. In order to improve the recognition accuracy, instead of using the result of the google recognizer, we built a web server where the user data are accumulated and they are used for recognition error correction.
