DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the drawings, the same reference numerals as in the drawings denote the same elements in the drawings, unless they are indicated on other drawings.

FIG. 1 is a schematic diagram showing an energy saving system using a behavior pattern of a resident according to the present invention, and FIG. 2 is a plan view of an indoor space showing an energy saving system.

Referring to FIGS. 1 and 2, an energy saving system 1 according to an embodiment of the present invention includes a sensing unit 100 and a control unit 200.

The configuration of the present invention will be described in detail as follows.

First, the sensing unit 100 senses the presence or absence of a resident of a plurality of rooms (hereinafter, referred to as 'space S') formed in each room, that is, inside the building. do.

Specifically, the detection sensor 110 includes a first sensor 111 provided outside the door G provided in each of the spaces S, S1 through Sn, and a second sensor 111 disposed inside the door G, And a sensor 113.

In this case, the detection sensor 110 may include at least a pressure sensor installed in the bottom material. That is, by applying the detection sensor 110 locally to the outside of the door G of each space, the number of the inserted sensors can be minimized.

The pressure sensor is generally used in various fields, and a detailed operation principle thereof will be omitted. Such a pressure sensor is inexpensive as compared with the infrared sensor, and thus the cost required for constructing the energy saving system according to the present invention can be reduced.

The control unit 200 determines the presence or absence of a resident for each space on the basis of the signal sensed by the sensing unit 100. The control unit 200 automatically conveys the convenience product 10 including the air conditioner, / Off.

More specifically, as shown in FIG. 3A, a signal is first sensed by a first sensor 111 installed outside a door G, and then a signal is transmitted from a second sensor 113 installed inside the door G If it is detected, the control unit 200 determines that the occupant has entered the space S.

3B, if a signal is sensed by the first sensor 111 installed outside the door G after the signal is first sensed by the second sensor 113 installed in the door G, The control unit 200 determines that the resident has left the space S.

Referring back to FIG. 1, the controller 200 may include a data storage unit 210 for data of a behavior pattern of a resident through sensing using the sensing unit 100.

The control unit 200 including the data storage unit 210 receives the real time sensing signal from the sensing unit 100 and the behavior pattern data of the occupant stored in the data storage unit 210, Is greater than a reference value. Then, the convenience product 10 is controlled on / off according to the determination result.

That is, the control unit 200 determines the behavior pattern of the resident rather than turning on / off the convenience product 10 immediately according to the signal detected by the sensing unit 100, and determines whether the behavior is improvised and repetitive And finally determines whether the product 10 is turned on / off.

For example, the reference value may be related to how many times the occupant repeats entering and leaving the space for a predetermined period of time. In other words, when a resident enters and exits the space S from time to time, the on / off operation is rather frequent and energy may be wasted. Accordingly, the control unit 200 measures how many times the occupant has entered and exited the space within a predetermined time, and can temporarily hold on / off control of the convenience product 10 when the measured value is equal to or greater than the reference value.

Also, the controller 200 can detect various information including the number of resident persons, the residence time, as well as the presence or absence of the resident for each space through the detection of the sensing unit 100.

Specifically, the control unit 200 can adjust the cooling / heating set value by grasping the occupant density in each space. In other words, when there is one resident in a limited space and when three or four persons are present, the room temperature may be higher due to body temperature. Therefore, the control unit 200 determines the occupant's occupancy, and if the occupant has a large number of occupants, the indoor temperature is set to be lower by the corresponding temperature in consideration of the room temperature increase due to the body temperature. On the contrary, when the occupant is one, the controller 200 sets the room temperature to a predetermined value.

More specifically, the following description will be given with reference to Table 1 below.

Staff room Setpoint 1 person 24 ℃ 2 people 23.5 DEG C 3 people 23 ℃ 4 people 22.5 DEG C

First, the control unit 200 sets the initial set value of the room temperature to 24 [deg.] C if the occupant is identified as one person in the space S through the sensing unit 100. [

In addition, when the occupancy rate increases in the space S, the indoor temperature set value per additional person is decreased by 0.5 ° C in consideration of the fact that the indoor temperature rises due to the body temperature of the resident.

Also, if the control unit 200 recognizes three persons as the occupant in the space S, the set value is set to 23 ° C. If the occupant has four occupants, the set value is set to 22.5 ° C.

In this way, the control unit 200 can reduce the energy compared to the case where the entire space S is cooled and heated to the same temperature by flexibly changing the room temperature set value according to the occupant of the space S in question.

Also, the control unit 200 can grasp the average return time of a resident who resides in the space S through the data stored in the data storage unit 210. Thus, by preheating the heating before the occupant enters the space, it is possible to reduce the time for preheating and heating for the initial heating, thereby providing an efficient heating environment for the residents.

Hereinafter, an energy saving method using the occupant's behavior pattern according to the present invention will be described.

First, the presence or absence of a resident for each space S is sensed through the sensing unit 100 (Step 1).

The control unit 200 determines whether there is a resident in the space S based on the signal detected by the sensing unit 100 and determines whether any one of the convenience products 10 including cooling / (Step 2).

In this case, the second step may include a step of converting the behavior pattern of the resident into data in the data storage unit 210 through detection using the sensing unit 100.

Therefore, based on the real time sensing signal from the sensing unit 100 and the behavior pattern data of the occupant stored in the data storage unit 210, it is determined whether or not the measured value in the sensing unit 100 exceeds the reference value And controls on / off the convenience product 10 according to the result.

In this case, the reference value may be related to how many times the occupant repeats the entry and exit of the space for a predetermined time.

In addition, the control unit 200 obtains various information including not only the presence of a resident for each space S, but also the number of staff members and residence time. That is, the control unit 200 may determine the residence density of the resident in the space S and then set the room temperature set value differently according to the room occupancy. That is, the room temperature set value is set to be low when the room S is large, and the room temperature set value is set to a predetermined value when the room S is small (see Table 1).

Also, the control unit 200 can grasp the average return time of the resident through the data stored in the data storage unit 210 and preheat the heating before the resident enters and exits the corresponding space.

The energy saving system and the method using the behavior pattern of the resident according to the present invention can detect whether a resident enters / exits in a corresponding space in a building in real time and automatically turn on / off heating / Off control.

In particular, in the control unit 200 of the present invention, the behavior pattern of the occupant is detected through the detection using the detection sensor 110, and it is determined whether the measurement value exceeds the reference value based on the data. Off control of the convenience product 10 even if the occupant repeatedly enters and exits the space, it is possible to prevent the on / off operation of the convenience product 10, thereby saving energy.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
