1 and 2, the home energy management system includes a home energy management server 100, an internal environment information collecting device 200, an external environment information collecting device 300, and an energy management device 400.

The home energy management server 100 generates control information by using the internal environment information received from the internal environment information collecting device 200 and the external environment information received from the external environment information collecting device 300 and based on the control information. The server controls the operation of the energy management apparatus 400.

To this end, the home energy management server 100 generates prediction data by using at least one of the internal environment information received from the internal environment information collecting device 200 and the external environment information received from the external environment information collecting device 300. do.

In one embodiment, the home energy management server 100 generates an occupancy pattern using the motion information received from the motion sensor 210 of the internal environment information collecting device 200 and then generates the occupancy prediction data according to the occupancy pattern. Create

More specifically, the home energy management server 100 analyzes the motion information received from the motion sensor 210 of the internal environment information collecting device 200 in units of time to extract a time zone during which motion is detected, and then uses the corresponding time zone. To create a room pattern. Thus, the occupancy pattern includes information on the time zone in which the user occupies the room.

Then, the home energy management server 100 generates room prediction data by predicting whether the user is indoors after a specific time based on the current time according to the room pattern.

In another exemplary embodiment, the home energy management server 100 may include sensing information received from the internal environment information collecting device 200, sensing information received from the external environment information collecting device 300, and a weather information providing server (not shown). Using the weather information received from the) to generate weather forecast data.

More specifically, the home energy management server 100 performs map learning based on external weather information for a specific time period or more received from the external environment information collecting device 300, and then wakes up at the next time point based on the current time point. To predict.

For example, the home energy management server 100 indicates that the temperature change trend from 1 AM to 1 PM received from the external environment information collecting device 300 indicates that the temperature is high, and the light intensity change trend indicates that the illuminance is high. In this case, it is predicted that the temperature and illuminance will increase in the next time zone based on the current time point.

For another example, the home energy management server 100 indicates that the temperature change trend from 4 pm to 7 pm received from the external environment information collection device 300 indicates that the temperature is lowered and that the light intensity change trend is lowered. If instructed, the temperature and illuminance will be lowered in the next time zone based on the current time point.

Then, the home energy management server 100 generates a control signal using the weather prediction data and the room prediction data.

In one embodiment, the home energy management server 100 applies the weather prediction data and the room prediction data to the deep learning algorithm to generate a control signal.

More specifically, the home energy management server 100 performs map learning based on weather forecast data and occupancy prediction data for each hour or more at a specific time, and then predicts energy consumption of the building based on the weather forecast data and the occupancy prediction data. After that, it generates the optimal control signal for the next time zone.

At this time, the home energy management server 100 determines whether each of the energy management apparatus 400 operates based on the weather forecast data and the occupancy prediction data, and the energy consumption of the building according to whether the energy management apparatus 400 operates. To predict.

For example, the home energy management server 100 is based on the weather prediction data, when the temperature is above a certain temperature, the illuminance is above a certain illuminance, and the user is occupied based on the occupancy prediction data, among the energy management apparatus 400. The electric blind 410 is operated to block external light, and the temperature controller 430 is operated to lower the internal temperature and operate the lighting 420. At this time, the electric blind 410 may block the solar heat flowing through the window and can significantly reduce the energy of the temperature controller 430.

For another example, the home energy management server 100 may perform energy management device 400 when the temperature is below a certain temperature based on the weather forecast data, the illuminance is above a certain illuminance, and the user is occupied based on the occupancy prediction data. The electric blind 410 is not operated so that external light enters the inside, and the temperature controller 430 is operated to increase the internal temperature and operate the lighting 420.

At this time, since the electric blind 410 does not operate, the temperature of the inside is increased by allowing sunlight to enter through the glass, and then the temperature controller 430 is operated to increase the temperature of the inside of the temperature controller 430. Energy can be greatly reduced.

In addition, the home energy management server 100 adjusts the ESS discharge start time by estimating the power peak load generation time based on the energy prediction consumption amount of the building and the PV generation amount.

For example, the home energy management server 100 starts the ESS discharge by predicting the power peak load generation time based on the energy prediction consumption and the PV generation amount of the building calculated based on the weather prediction data and the planting prediction data as shown in FIG. 3. Adjust the time as in reference (a).

The internal environment information collecting device 200 includes a motion sensor 210, a temperature sensor 220, a humidity sensor 230, and an illuminance sensor 240.

The motion sensor 210 senses a motion of an object inside and provides motion information to the home energy management server 100.

The temperature sensor 220 senses an internal temperature and provides temperature information to the home energy management server 100.

The humidity sensor 230 senses the humidity inside and provides humidity information to the home energy management server 100.

The illuminance sensor 240 senses the illuminance therein and provides the illuminance information to the home energy management server 100.

The electricity meter and the temperature sensor 300 sense the amount of solar power generation and the module temperature, and provide the power amount and the module temperature information to the home energy management server 100.

The external environment information collecting device 300 includes a temperature sensor 310, a humidity sensor 320, and an illuminance sensor 330.

The temperature sensor 310 senses an external temperature and provides temperature information to the home energy management server 100.

The humidity sensor 320 senses an external humidity and provides humidity information to the home energy management server 100.

The illuminance sensor 330 senses an external illuminance and provides humidity information to the home energy management server 100.

The energy management device 400 includes an electric blind 410, an illumination 420, and a temperature controller 430.

The motorized blind 410 is formed in the air layer after forming an air layer at predetermined intervals on two glass plates. A motor is formed in the electric blind 410 and is adjusted up, down, and angle according to a control signal received from the electric blind control module 510 or a control signal received from the electric blind control module 510.

As described above, since the electric blind 410 is embedded in the air layers of the glass plates, it is possible to fundamentally block a concern due to breakage, contamination, etc., and to block the solar heat flowing through the windows and to significantly reduce the cooling energy.

In this case, the solar selective transmissive glass coating technology is applied to the glass plate on which the electric blinds 410 are formed. As described above, when the solar selective transmissive glass coating technology is applied to the glass plate, selective blocking of ultraviolet rays and infrared rays while simultaneously transmitting visible light regions minimizes the influx of solar energy incident through the windows, while the light is not reduced. It has performance and at the same time realizes excellent surface hardness and semi-permanent durability of the coated surface.

For this reason, the solar selective transmissive coating glass applied to the outside primarily blocks the sun's heat and the electric blind 410 blocks the solar heat in the first place. The coating glass applied to the outside is primarily blocked to improve the durability of the electric blind 410.

The lighting 420 is controlled to turn on, turn off, brightness, temperature, etc. according to a control signal received from the lighting control module 520. The lighting 420 may be implemented as an LED module or the like.

The temperature controller 430 adjusts the temperature according to the control signal received from the temperature controller control module 530.

On the other hand, the above-described motion detection sensor 210 will be described.

The above is described only as a motion sensor, and accordingly, the motion is determined only when there is behavior of the occupant. However, in the case of occupants usually have a form in which only a slight fine movement is seen in place.

In general, as the motion sensor recognizes the movement through microwave or pixel analysis, the technology has been secured to a level that can detect even small fine movements in recent years. In this case, since the number of errors is large, the accuracy is inevitably deteriorated.

Therefore, the motion sensor 210 according to the present invention is provided so that the detection range overlaps the wall and the ceiling of the reference space for occupant determination. And the motion sensor 210 is adapted to receive the reflection of the object after the output of the microwave wave to detect the object and the movement of the object.

In this case, since the microwave wave according to the motion sensor is received after being reflected through a predetermined reflection angle (the reflection of a wave-type source hitting the output after being reflected is determined), the motion sensor installed on the wall and ceiling Although microwave waves may be used in the same frequency domain, they may be selectively used among frequency domains within 1 to 20 GHz in order to prevent interference in a case.

On the other hand, the home energy management server 100, in any one of the two motion detection sensor, when the object is detected at a position where the object including a person was previously detected, primarily determines that the occupant is present.

If no fine motion is detected for a predetermined time after the primary occupant is determined, it is determined that there is no occupant, and the determination information of the primary occupant is deleted.

In this case, the criterion for the detection of fine motion refers to a case where motion is detected in both of the two motion detection sensors 210 provided on the wall and the ceiling.

If the movement is not detected in both, that is, if the movement is not detected in the lateral direction or the planar direction, it may be determined that the occupants do not exist as above.

If the motion is detected only in one of the two, the fine motion detection time extends the predetermined time for a predetermined time (for example, 10 seconds to 1 minute).

Accordingly, it is determined that the occupant is present when the motion is detected by both motion sensors for an extended time, or that the occupant is not present when the motion is not detected by both motion sensors.

On the other hand, as described above, in the case of performing home energy management in accordance with the association of the weather prediction data and the weather prediction data, as the predetermined time is extended as described above, the following problem may occur.

For example, the temperature and illuminance of the next time zone were predicted according to the temperature change and the illuminance change of the temperature from 4 pm to 7 pm, and home energy management should be performed based on the room prediction data for the next time zone. However, as the predetermined time is extended as described above, the time zone for the temperature and illuminance prediction may be over 7 pm, and thus confusion may occur in the prediction of the occupancy and the processing of the information on the temperature and the illuminance prediction.

In order to prevent this, the home energy management server 100 exceeds a predetermined time period for the temperature and illuminance prediction by the above-described sensing operation by the motion sensor 210, for example, from 4 pm to 4 pm If the time is set to 7 o'clock, and motion detection is over 1 minute than 7 pm, the information by the motion sensor detected until 7:05 pm is assumed if the over range of the above predetermined time is about 5 minutes. Can be retroactively processed in the previous time zone (4 pm-7 pm) to allow information processing. However, based on the system log, the detection started within the previous time zone (4 pm to 7 pm) may be applied only when the time zone is exceeded according to the time extension.

Although specific embodiments of the present invention have been described so far, various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the claims below, but also by the equivalents of the claims.

As described above, the present invention has been described by way of limited embodiments and drawings, but the present invention is not limited to the above-described embodiments, which can be variously modified and modified by those skilled in the art to which the present invention pertains. Modifications are possible.
