The VBR Vibration Sensor by M.D. Micro Detectors has been successfully tested and installed in the escalators of one of the most important and crowded metropolitan areas of the planet. That of Seoul in South Korea has 607 stations and is one of the most used urban transport systems in the world, with over 8 million daily trips on a system of 19 lines. In October 2017, IoT technology was applied to 100 escalators of subway line 7, reducing repair time from 56 minutes to 37 minutes per failure. The number of problem reports also decreased by 15% from an average of 20.5 to 17.4. The escalator exploits the IoT technology and installs 20 to 40 sensors (of different types, including our VBR), which allow to identify the reason for faults immediately after their occurrence. The insiders are able to immediately send the necessary replacement parts where the failure occurred, greatly reducing the recovery time. In the past, however, the procedure adopted consisted in reporting the malfunction to the dedicated site, checking the malfunction and, only then, preparing the equipment necessary for repair. Information collected through IoT technology are used in preventive maintenance. For example, the Seoul subway analyzed the vibration frequency data of the escalator drive part at the Guangzhou station of line 5 avoiding an accident by intervening on the engine base.

The device for IoT technology for escalators and the vibration analysis system is applied to the escalator equipment by a digital system designed to analyze and maintain the state of the machines. The company is planning to promote the digital metro innovation project by implementing the system to the subway infrastructure, power supply, signal control and information communication area.

IoT technology will be applied to 250 escalators by the end of this year and will be introduced in 1334 cars by 2022.
