Description

Power management system through evaluation of activity level by generation {System for power operation through evaluation of activity level by generation}

The present invention relates to electrical installations of buildings. More specifically, it relates to a power management system for efficiently managing power based on the amount of activity of members of each household and considering the characteristics of each household.

An apartment house is a form of housing in which a plurality of households or a plurality of households co-occupy in one building.

A distributing board means a device that distributes power to each household of an apartment house and has instruments, switches, safety devices, etc. necessary for controlling distribution.

A panel board refers to a device that branches electric power supplied from the panel board to each room within a household and includes instruments, switches, safety devices, and the like necessary for controlling the branching.

In recent years, due to the development of IT technology, the functions of a switchboard or distribution board are increasingly diversified, and power consumption can be optimized by monitoring power information consumed in the switchboard or distribution board and transmitting the monitoring result to an external device through a network. Development of smart power management technology is being carried out.

However, the conventional power management technology is used only to the extent that it is reflected in future power management by using only the power use information of each generation generated in the switchboard or the switchboard itself.

Accordingly, it is necessary to develop a technology capable of more efficiently managing power by considering not only the power use information of each generation but also the characteristics of each generation.

On the other hand, since the switchboard or switchboard is exposed to the outside, there is a problem in that safety accidents such as unintentional power cutoff or electric shock occur when the switchboard or switchboard is arbitrarily manipulated by an outside intruder or an infant, not a manager.

Then, the management server 200 may control the switchboard 110 according to the permissible boundary value for each household determined in step S130 (S140). That is, when the electric load of each household exceeds the allowable threshold set for each household, the management server 200 may control the switchboard 110 to cut off power of the household exceeding the allowable threshold.

In addition, the management server 200 may control the sub board 120 according to the determined permissible boundary value for each zone within the household. That is, the management server 200 may control the distribution panel 120 to cut off power in the area exceeding the allowable threshold when the electric load for each zone of each household exceeds the allowable threshold set for each zone of each household.

6 and 7 are exemplary views for explaining the function of the electric box device according to an embodiment of the present invention.

As shown in FIG. 6 , when the user performs a pressing operation on the button member 130, the control unit 107 identifies a pressing operation pattern of the button member 103, and the identified pressing operation pattern corresponds to a preset value. If they match, it can be determined that the person who pressed the button member 103 is a pre-registered user.

That is, the controller 107 may determine whether the pressing motion patterns match based on the number of pressing operations performed during a preset time period, the time interval between the pressing operations, and the pressure of each pressing operation.

For example, as shown in FIG. 7 , the pressing operation pattern presses the button member with a first pressure for 1 s (A), presses the button member with the first pressure for 2 s after 0.5 s (B), then presses the button member for 1 s after 2 s. It may be a pattern of pressing (C) with a first pressure during 0.5s and pressing (D) with a second pressure stronger than the first pressure for 1s after 0.5s.

In this way, the electric box device 100 according to an embodiment of the present invention receives the pressure sensed by the button member according to the user's pressing operation, and the person who pressed the button member based on the received pressure is already registered. In the case of a user, the security of the electric box can be enhanced by unlocking the door of the electric box through the locking member.

8 is an exemplary diagram for explaining a power management method according to an embodiment of the present invention.

As shown in FIG. 8, within each household or within each household area, an access point for transmitting a Wi-Fi signal is provided on one side, and a Wi-Fi receiver receives a Wi-Fi signal from the access point on the other side opposite to one side. (receiver) may be provided.

Here, when there is a motion of the object A within each household or within each household zone, interference of the Wi-Fi signal received from the access point to the Wi-Fi receiver occurs. Here, object A may be a member of a household residing within a household.

Accordingly, the management server 200 estimates the existence of the movement of the object A within the household or within the household area based on a pattern of change in Wi-Fi signal strength for each unit time set in advance, and estimates that the movement of the object exists. The amount of activity for each generation can be evaluated on the basis of the number and frequency of unit time.

That is, the management server 200 may use whether or not a resident moves within a household as an index for activity evaluation. For example, the management server 200 may evaluate the amount of activity per household as high as the number and frequency of unit time estimated to have movement of objects per household are higher.

As such, the management server 200 according to an embodiment of the present invention evaluates the amount of activity of members of the household within each household, determines the permissible threshold value for the amount of electricity load for each household according to the evaluated amount of activity, and controls the switchboard. By doing so, it is possible to efficiently manage power in consideration of the characteristics of each generation.

As described above, although preferred embodiments of the present invention have been disclosed in the present specification and drawings, it is in the technical field to which the present invention belongs that other modified examples based on the technical spirit of the present invention can be implemented in addition to the embodiments disclosed herein. It is self-evident to those skilled in the art.
