Power facilities such as distribution boards, distribution boards, motor control panels, emergency generators, etc., which are installed in building units such as schools or group residential facilities, or sub-region units, are scattered independently of each other in necessary areas. It requires a lot of manpower and money.

In particular, these power facilities are hazardous facilities that handle high or special high pressures, but they are not facilities that can be arranged with regular managers. Therefore, they are generally installed in narrow spaces in the basement to prevent safety accidents and improve the efficiency of building spaces. As a result, maintenance and management of most individual switchboard facilities is also very inconvenient.

In addition, since the generation and recording of a series of management information related to facility maintenance inspection, breakdown repair and maintenance of current electric power facilities are collected at the central management center through individual managers, the statistics of overall management information and recognition of the on-site situation are recognized. This requires a considerable time or due date, which makes it impossible to check real-time management.

The lack of real-time management of power facilities, including switchgear facilities, is an issue that needs to be urgently improved in view of the characteristics of power facilities that struggle with troubleshooting and maintenance.
