Prevent accidents in advance by detecting rail temperature and cable tension.

SK Telecom and Busan Transportation Corporation have decided to utilize cutting-edge IoT and big data technologies to manage urban railways more safely.

SK Telecom announced on the 15th that it signed a memorandum of understanding with Busan Transportation Corporation to promote the development and demonstration of a 'smart urban railway standard model'.

Starting in April, the two companies will install "railway IoT sensors" at Busan subway stations and other locations for approximately two years to monitor facilities in real time. Each sensor will utilize SK Telecom's LoRa network.

The main elements monitored in real time by IoT sensors are ▲temperature and humidity ▲fine dust ▲fire occurrence ▲escalator vibration within the station, and ▲rail temperature ▲trolley line tension in the above-ground section of the train.

The two companies expect that if the 'Smart Urban Railway Standard Model' is applied, railway safety and management convenience will increase.

We are also developing a real-time control system using the railway integrated wireless communication network (LTE-R), including ▲power on/off devices and ▲subway shutter control sensors. Previously, station staff manually managed the lighting and shutters according to the first and last train times.

Busan Transportation Corporation is considering introducing a 'smart urban railway standard model' to the Sasang-Hadan and Yangsan light rail lines, which are scheduled to open in 2022.

SK Telecom's Public Works Division Director Choi Il-gyu said, "SK Telecom's IoT technology will make the Busan subway significantly safer," and added, "Based on this demonstration project, we hope that IoT technology will be fully introduced to urban railways in the future."
