Remote-control System for Elevator with Sensor Technology

Elevators are essential in high-rise buildings.Their principle is simple but they have many devices and functions for safe operation and effective management.The development of new technologies based on the Internet of Things (IoT) and high-rise building technology allows improved elevator systems with remote control and intelligent operation.Many studies have proposed new functions for safety management, efficient operation, and effective data collection and storage.However, remote-control technology is required for advanced elevator systems, especially those based on recent technologies such as the IoT and sensor technology.Therefore, a study was carried out to provide the required basic information on what should be sensed, which sensors should be used, and where they should be installed in a remote-control elevator system.For this study, we designed a questionnaire to define the issues with the help of experts.The replies to the questionnaire were analyzed using the Delphi method, and the results suggest that 18 major tasks must be performed when designing an elevator system appropriate for remotecontrol and intelligent operation.We propose the monitoring items, related sensors or devices, and their installation locations for an intelligent elevator system.A design based on the results of this study is expected to contribute to the development of an improved intelligent and remotecontrol elevator system.The results enable subsequent research on the technological requirements of the equipment and the establishment of maintenance and management strategies for the proposed elevator system.
