In addition, when a power supply is always required when there is a person as well as when there is no person, the system is configured separately.

For this reason, the purpose of implementing a smart factory is not achieved, and the reality is that most of the restricted area, that is, the degree of controlling access by installing a door lock having a sign or password that is simply a restricted area in a space where security is required.

In addition, although there are some occasions where a biometric device is emerging as a hot topic in recent years, it is true that it is too expensive to manage and place the device in all restricted areas. In addition, most of them are not able to know when, how, and who went in a restricted area, and there is a problem in that unauthorized access is frequently made by stealing a password or a key. As a way to solve this problem, a method of recording access status by CCTV in a restricted area has been proposed, but there is still a problem of storing recorded data, and CCTV is for simple shooting and cannot be linked with the existing door lock system. There is. It is also difficult to safely evacuate and respond to all personnel in unforeseen disasters such as fires. In addition, the RFID card adopted by most companies merely reflects the commute, access and work attitude.

The problem to be solved in the present invention is to provide a method for controlling the power of the factory using indoor location-based services.

Another problem to be solved by the present invention is to provide a system for controlling the power of the factory using indoor location-based services.

Another problem to be solved by the present invention is to provide a new method and system that can enhance security with power control using indoor location-based services.
