  Abstract

‘NB-IoT Manhole Surveillance Solution" has been developed to safely manage manholes and facilities that are applied with 3GPP NB-IoT. It can remotely monitor the opening of the manhole cover and the air quality inside the manhole, thereby preventing accidents that may be caused by the manhole. Conventionally, there were methods to remotely manage manholes, but they were not widely used because of propagation attenuation caused by manhole cover made of cast iron, cast steel. It compensates for propagation attenuation by manhole covers through the coverage enhancement characteristics of NB-IoT, is designed to operate as battery because there is no power supply facilities inside a manhole, and 3GPP’s PSM is applied to minimize power consumption. In addition, ‘Adjustable Length Mounting Frame" was invented for use in manholes of various sizes so that it is possible to save time and cost due to no construction. It was verified by applying to the telecom manhole as a preliminary step for commercialization. In the future, when planning to design a smart city is required the development and adaptation of solutions that can remotely monitor various underground facilities as well as manhole, and these will protect the life and property of the people from accidents.
