Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an air conditioning system,

The present invention relates to an air conditioning system and a control method thereof.

The air conditioning system is a system for keeping the air in a predetermined space in a most suitable state according to the purpose of use. Generally, the air conditioning system includes a compressor, a condenser, an expansion device, and an evaporator, and a refrigerant cycle for compressing, condensing, expanding, and evaporating the refrigerant is driven to cool or heat the predetermined space.

At this time, the predetermined space may be variously proposed according to the place where the air conditioning system is used. For example, when the air conditioning system is used in a home or an office, the predetermined space may be a house or an indoor space of a building. In addition, when the air conditioning system is used in an automobile, the predetermined space may be a boarding space on which a person is boarded.

A technique for automatically controlling the air conditioning system by determining the presence of a user who needs conditioned air in the predetermined space has recently been developed. The prior art information related to these technologies is as follows.

(1) First Prior Art: Registered Patent No. 10-1074300, Method of Controlling Air Conditioning Based on Resident Behavior.

(2) Second Prior Art: Patent No. 10-1470540, air conditioner and control method thereof.

These prior documents require a separate sensing device, such as an infrared sensor, to identify the user's presence. Such a sensing device has a problem that it is difficult to accurately grasp the existence of a user. For example, in the case of the infrared sensor, it is possible to recognize a non-human animal and a device for emitting heat.

Also, this sensing device is very expensive equipment. Therefore, there is a problem in that the price competitiveness is deteriorated when a separate apparatus is provided. In addition, there is a problem in that reliability of such a sensing device can not be ensured and replacement is necessary because of the life span.

The present invention provides an air conditioning system and an air conditioning system for controlling an indoor unit adjacent to a user by receiving an AP list from a user's mobile terminal without providing a separate sensing device.

The present invention also provides an air conditioning system and a control method thereof for efficiently determining a space by controlling whether or not a user is present in a place adjacent to an indoor unit to perform a power saving operation or a rapid operation.

The air conditioning system according to the present invention includes a plurality of indoor units installed at different positions, at least one outdoor unit connected to the plurality of indoor units, and a control unit for controlling the plurality of indoor units and the at least one outdoor unit , The control unit includes a user AP receiving unit receiving a list of APs from a mobile terminal equipped with an AP (Access Point) signal detecting module, an AP list received by the user AP receiving unit, and APs corresponding to locations where the plurality of indoor units are installed An AP processing unit for calculating the similarity by comparing the lists, and an indoor unit determining unit for determining indoor units adjacent to the mobile terminal according to the degree of similarity calculated by the AP processing unit.

The control unit further includes an AP storage unit storing an AP list corresponding to a location where the plurality of indoor units are installed, and the AP processing unit compares the AP list received by the user AP receiving unit and the AP list stored in the AP storage unit The degree of similarity can be calculated.

Wherein the plurality of indoor units are each provided with an AP signal detecting module and the control unit further comprises an indoor unit AP receiving unit for receiving an AP list from the plurality of indoor units, The similarity can be calculated by comparing the list of APs received by the indoor unit AP receiving unit.

The AP list may include signal strengths of a plurality of APs and APs.

The AP processor may calculate the similarity using the Euclidean distance.

The AP processor calculates a degree of similarity between the mobile terminal and each indoor period by summing squared differences of signal strengths when there is a corresponding AP and squaring differences between the signal strengths when there is no corresponding AP .

The indoor unit determination unit may determine that the mobile terminal is located adjacent to the indoor unit when the value calculated by the AP processing unit is smaller than a predetermined reference.

The user AP receiving unit receives each AP list from a plurality of mobile terminals, and the AP processing unit can calculate the similarity between each mobile terminal and the plurality of indoor periods.

The control unit may further include an indoor unit control unit for controlling the plurality of indoor units, and the indoor unit control unit may control the indoor unit in which the adjacent mobile terminal is not located to be OFF or in a power saving mode.

The control unit may further include an indoor unit controller for controlling the plurality of indoor units, and the indoor unit controller may control the indoor units adjacent to the indoor units in a rapid mode in which the indoor units are larger than a predetermined reference.

The present invention also provides a control method of an air conditioning system including a plurality of indoor units installed at different positions, the method comprising: receiving an AP list from a mobile terminal, And a list of APs corresponding to the positions of the plurality of indoor units, calculates the similarity, determines indoor units adjacent to the mobile terminal based on the calculated similarities, and operates the indoor units determined to be adjacent.

The AP list corresponding to the position where the plurality of indoor units are installed can be stored.

The AP list can be received from the plurality of indoor units and compared with the AP list received from the mobile terminal to calculate the similarity.

The degree of similarity can be calculated using the signal strength of each AP included in the AP list of the mobile terminal and the signal strength of each AP included in the AP list of each indoor unit using the Euclidean distance.

When the value calculated using the Euclidean distance is smaller than a predetermined reference, it can be determined that the mobile terminal is located adjacent to the indoor unit.

According to the present invention, when the indoor unit and the user do not exist adjacent to each other, energy efficiency can be increased as the indoor unit is operated in the power saving mode.

Further, when a large number of users are present adjacent to the indoor unit, the indoor unit is operated in the rapid-mode operation, thereby providing more comfortable air to the user.

In addition, it is possible to know the location information of the user by using the installed AP and to control the indoor unit accordingly. Particularly, since the position of the user is matched with the indoor unit by using the mobile terminal possessed by the user, a separate sensing device is not necessary and the price competitiveness can be enhanced.

In addition, since the AP list formed in the mobile terminal is generally used, the user does not need to take any other action, which is advantageous to the user.

Also, there is an advantage that it is not necessary to separately receive the AP list of the indoor unit since the AP list of the place where the indoor unit is located is inputted once, at first.

Also, since the indoor unit is provided with the AP signal detection module, it is possible to compare the position information of the indoor unit with the position information of the user more accurately.

1 is a view illustrating an air conditioning system according to an embodiment of the present invention.

1, an air conditioning system according to an embodiment of the present invention includes a plurality of indoor units 10, at least one outdoor unit 20, and a control unit (not shown) for controlling the indoor unit 10 and the outdoor unit 20 100).

In FIG. 1, connections between the indoor unit 10, the outdoor unit 20 and the control unit 100 are briefly shown.

The indoor unit (10) and the outdoor unit (20) may be connected to each other through a refrigerant pipe so that the refrigerant flows and forms a refrigerant cycle. In addition, a distributor may be provided so that a plurality of indoor units 10 are connected to one outdoor unit 20 to be driven. Such a configuration is used in a general air conditioning system, and a detailed description thereof will be omitted.

The control unit 100 may be connected to the indoor unit 10 and the outdoor unit 20 through a communication line. That is, the control unit 100 may receive the driving information of the indoor unit 10 and the outdoor unit 20, and may issue a predetermined control command to the indoor unit 10 and the outdoor unit 20.

The control unit 100 may be variously connected to the indoor unit 10 and the outdoor unit 20. For example, the control unit 100 may be connected to the indoor unit 10 and the outdoor unit 20, respectively. The control unit 100 may be connected to the outdoor unit 20 and the outdoor unit 20 may be connected to the indoor unit 10.

Although one outdoor unit 20 is shown in FIG. 1, the outdoor unit 20 may be a plurality of outdoor units. 1, the indoor unit 10 is illustrated as a ceiling type indoor unit. However, the indoor unit 10 may be provided in various forms such as a stand type, a wall type, and the like. .

At this time, the plurality of indoor units 10 according to the present invention are installed at different positions. The different positions mean that the indoor units 10 are spaced apart from each other by a predetermined distance. For example, the indoor unit 10 may be installed in each room in a space having a plurality of rooms. They can also be installed separately from one room or on different floors within a building.

The present invention relates to a plurality of indoor units (10) and the control unit (100) for controlling the plurality of indoor units (10), and contents related to the outdoor unit (10) will be omitted. Hereinafter, the configuration of the control unit 100 will be described in detail.

2 is a view illustrating the configuration of an air conditioning system according to an embodiment of the present invention.

As shown in FIG. 2, the control unit 100 is provided with various configurations. For convenience of explanation, only the configuration related to the features of the present invention will be shown and described, and the rest of the configuration will be omitted. The plurality of indoor units 10 includes a first indoor unit 11 and a second indoor unit 12 to an Nth indoor unit 18.

The control unit 100 is provided with a user AP receiving unit 110 receiving a list of APs from a mobile terminal 200 having an AP (Access Point) signal detecting module 200a.

The mobile terminal 200 includes a smart phone possessed by a user. Also, the AP signal detection module 200a means a Wi-Fi detection function provided in a smart phone. That is, the AP list can be understood as a 'connectable Wi-Fi list' retrieved from a smartphone.

Also, even if the user does not use the Wi-Fi function in the mobile terminal 200, the 'connectable Wi-Fi list' may not require the user's action because the smart phone itself is searched.

The AP list may include signal strengths of a plurality of APs and APs. AP means a router or the like arbitrarily installed in each place. For example, these APs are installed in a room with as few as six, as many as 45. In particular, more APs can be installed in an environment where smart phones and the like are becoming commonplace.

Such an AP does not correspond to a configuration of the air conditioning system of the present invention, and the present invention uses only an AP installed in general.

Although the mobile terminal 200 is shown in FIG. 2 for convenience of description, the mobile terminal 200 does not correspond to a configuration of the air conditioning system. That is, the mobile terminal 200 corresponds to an example of a device for transmitting predetermined information to the user AP receiving unit 110.

The mobile terminal 200 may be configured to transmit the AP list to the user AP receiving unit 110 at predetermined time intervals. At this time, the mobile terminal 200 can transmit the AP list at the time of transmission to the user AP receiving unit 110.

2, the mobile terminal 200 transmits predetermined information to the user AP receiving unit 110. However, when the user AP receiving unit 110 receives a signal for requesting information from the mobile terminal 200, As shown in FIG. Accordingly, when the user AP receiving unit 110 has requested the mobile terminal 200, the mobile terminal 200 can transmit the AP list at that time to the user AP receiving unit 110.

The control unit 100 includes an AP processing unit 120 for comparing the list of APs received by the user AP receiving unit 110 with the list of APs corresponding to the locations of the plurality of indoor units 10, . In this case, 'similarity' is a measure of similarity between AP lists, and the calculation method will be described later.

The control unit 100 further includes an AP storage unit 150 in which a list of APs corresponding to the positions where the plurality of indoor units 10 are installed is stored. That is, the AP processing unit 120 may compute the similarity by comparing the list of APs received by the user AP receiving unit 110 with the list of APs stored in the AP storage unit 150.

As described above, since the plurality of indoor units 10 are installed at different positions, they have different AP lists. For example, different AP types and numbers may be included, or even the same AP may have different signal strengths.

The AP storage unit 150 stores an AP list of the location where the indoor unit 10 is installed when the indoor unit 10 is installed. For example, the installer installs the indoor unit 10 in a predetermined space, and stores the AP list of the corresponding location in the AP storage unit 150 using a smart phone or the like.

At this time, since the position of the indoor unit 10 is not changed once installed, it is sufficient to store the AP list once. In addition, the indoor unit 10 does not require a separate device through the above process.

The AP processing unit 120 may calculate the similarity using the Euclidean distance. In particular, the AP processing unit 120 may calculate the similarity by calculating the Euclidean distance between the AP list received by the user AP receiving unit 110 and the AP list of each indoor unit stored in the AP storage unit 150. [

For example, the AP processing unit 120 calculates the Euclidean distance of the AP list received by the user AP receiving unit 110 and the AP list of the first indoor unit 11 stored in the AP storage unit 150. The Euclidean distance between the AP list received by the user AP receiving unit 110 and the AP list of the second indoor unit 12 to the Nth indoor unit 18 stored in the AP storage unit 150 is calculated

A detailed calculation method will be described later with reference to FIG.

The control unit 100 is also provided with an indoor unit determination unit 130 that determines an indoor unit 10 adjacent to the mobile terminal 200 according to the degree of similarity calculated by the AP processing unit 120.

The indoor unit determination unit 130 may determine that the mobile terminal 200 is positioned adjacent to the indoor unit 10 when the value calculated by the AP processing unit 120 is smaller than a predetermined reference. At this time, it can be understood that the adjacently positioned mobile terminal 200 is located in the influence zone of the indoor unit 10. [

A predetermined criterion can be set to a predetermined value through an experiment. For example, when the indoor unit 10 is installed in each room, it is possible to set a range of an AP list generated when the mobile terminal 200 is located in a room where the indoor unit 10 is installed. A criterion determining that the mobile terminal 200 is located in the room where the indoor unit 10 is installed can be calculated through the range of the AP list.

Accordingly, the indoor unit determination unit 130 can determine that the mobile terminal 200 is located adjacent to any one of the plurality of indoor units 10. [

The control unit 100 further includes an indoor unit controller 140 for controlling the plurality of indoor units 10, respectively. The indoor unit controller 140 may drive the indoor units 10 according to the result of the determination by the indoor unit determination unit 130. [

For example, when it is determined by the indoor unit determination unit 130 that the mobile terminal 200 is located adjacent to the first indoor unit 11, the indoor unit controller 140 controls the first indoor unit 11 can be driven.

Also, as the user moves, the AP list of the mobile terminal 200 can be changed. Accordingly, the user AP receiving unit 110 receives the modified AP list and transfers the received AP list to the AP processing unit 120, and the AP processing unit 120 returns the similarity to the AP list stored in the AP storage unit 150 again .

When it is determined by the indoor unit determination unit 130 that the mobile terminal 200 is located adjacent to the second indoor unit 12, the indoor unit control unit 140 determines that the first indoor unit 11 And the second indoor unit 12 can be driven.

Through this process, the control unit 100 can drive each indoor unit 10 according to the position of the user.

3 is a view illustrating the configuration of an air conditioning system according to another embodiment of the present invention.

3, when each indoor unit 10 includes the AP signal detection modules 11a, 12a and 18a and the control unit 100 includes the AP reception unit 160 instead of the AP storage unit 150 described above Respectively. The description of the configuration described with reference to FIG. 2 will be omitted and the above description will be referred to.

AP signal detecting modules 11a, 12a, and 18a are provided in the first indoor unit 11 to the Nth indoor unit 18, respectively. As described above, the AP signal detection modules 11a, 12a, and 18a may be understood as a kind of communication module that means a Wi-Fi detection function.

Each of the AP signal detecting modules 11a, 12a, and 18a is not necessarily installed directly in each indoor unit 10, but is installed in a space where the indoor units 10 are installed. For example, an AP signal detection module disposed in a space where the indoor units 10 are installed can be used.

The indoor unit AP receiving unit 160 is provided to receive the AP list from the plurality of indoor units 10. Accordingly, the AP processing unit 120 may calculate the similarity by comparing the list of APs received by the user AP receiving unit 110 with the list of APs received by the indoor unit AP receiving unit 160.

The similarity can be calculated more effectively as the AP list is continuously received rather than using the stored AP list once. In addition, the indoor unit determination unit 130 can more effectively determine the indoor unit 10 adjacent to the mobile terminal 200, and the indoor unit control unit 140 can effectively operate the indoor unit 10. FIG.

FIG. 4 is a view illustrating an operation state of the air conditioning system according to an embodiment of the present invention, and FIG. 5 is a diagram illustrating an AP list processed in the air conditioning system according to an embodiment of the present invention. Figs. 4 and 5 illustrate operation by the above-described configuration by way of example.

FIG. 4 shows an exemplary situation in which the plurality of indoor units 10 are installed. In detail, the indoor unit 10 is provided with eight rooms provided with the respective rooms.

For convenience of explanation, the first chamber 300, the second chamber 310, the third chamber 320, the fourth chamber 330, the fifth chamber 340, the sixth chamber 340, 350, a seventh room 360, and an eighth room 370. In addition, a passage is provided between the first chamber 300 and the fourth chamber 330, and between the fifth chamber 340 and the eighth chamber 370.

The plurality of indoor units 10 are installed in each room and include a first indoor unit 11 installed in the first room 300, a second indoor unit 12 installed in the second room 310, A third indoor unit 13 installed in the third room 320, a fourth indoor unit 14 installed in the fourth room 330, a fifth indoor unit 15 installed in the fifth room 340, The sixth indoor unit 16 installed in the sixth chamber 350, the seventh indoor unit 17 installed in the seventh room 360 and the eighth indoor unit 18 installed in the eighth room 370 .

That is, it is assumed in FIG. 2 that the Nth indoor unit is provided as the eighth indoor unit and the AP list of the first indoor unit 11 to the eighth indoor unit 18 is stored in the AP storage unit 150.

4 shows a plurality of arbitrarily installed APs. For convenience of explanation, six APs are installed at arbitrary positions. In general, the APs are installed in a larger number and can be installed in each room for the convenience of the user. Accordingly, the accuracy of the result according to the present invention can be further enhanced.

FIG. 5 exemplarily shows an AP list, which is arbitrarily created for the sake of convenience of description and is not related to actuality. 5A is a list of AP searched by the mobile terminal 200 of the user.

For example, when the user (U, USER) holding the mobile terminal 200 exists in the seventh room 360 as shown in FIG. 4, when A disposed in the seventh room 360 has the highest signal strength , And B may have the next stronger signal strength. Further, the signal of the remote E may not be caught. Accordingly, the AP list as shown in FIG. 5 (a) can be searched by the mobile terminal 200.

5 (b) and 5 (c) show the AP list of any one of the plurality of indoor units 10.

5 (b) is very similar to the AP list of the mobile terminal 200 shown in FIG. 5 (a), and thus FIG. 5 (b) And can be predicted as the indoor unit 17. 5C can be predicted by the fifth indoor unit 15 installed in the fifth chamber 340 because the signal of F is strongest and the signal of C is not caught.

Through the AP list, the AP processing unit 120 calculates the degree of similarity. As described above, the similarity can be calculated by Euclidean distance.

In detail, when there is a corresponding AP, the AP processing unit 120 squares the difference of the signal strengths thereof, and if there is no corresponding AP, ) And each indoor unit 10 can be calculated.

For example, the Euclidean distance of the AP list retrieved from the user's mobile terminal 200 and the AP list of the indoor unit 10 shown in FIG. 5 (b) is calculated. At this time, since all APs correspond to each other, a value obtained by squaring the signal strength difference of each AP is obtained.

Specifically, the difference of the signal intensity corresponding to A is squared 2, the difference of the signal intensity corresponding to B is squared, the square of the difference of the signal intensity corresponding to C is squared, and the signal corresponding to D The square of the difference of 13, squared, and the square of 11, which is the difference of the signal strength corresponding to E, is added. If you get the value in this way, you can get the value 339.

Also, the Euclidean distance of the AP list retrieved from the mobile terminal 200 of the user and the AP list of the indoor unit 10 shown in FIG. 5C is calculated. In this case, the corresponding AP is A, B, D, and E, which is obtained by squaring the signal intensity difference of each AP, and C and F, which are not corresponding APs, squared each signal intensity difference.

Specifically, the difference of the signal intensity corresponding to A is squared, the square of the signal intensity corresponding to B is squared, the square of the signal intensity corresponding to D is squared, and the signal corresponding to E Add the square of 21, which is the difference in strength, squared. Also, the signal strength of C is squared and the signal strength of F is squared. If you get the value in this way, you can get a value of 13544.

According to the calculated value, the indoor unit determination unit 130 can find the indoor unit 10 adjacent to the mobile terminal 200. [

6 is a view illustrating the configuration of an air conditioning system according to another embodiment of the present invention.

FIG. 6 shows a case of receiving an AP list from a plurality of mobile terminals 200. FIG. The plurality of mobile terminals 200 includes a first mobile terminal 210 having an AP signal detection module 210a, a second mobile terminal 220 having an AP signal detection module 220a, And an Nth mobile terminal 280 equipped with a mobile terminal 230a.

As described above, the mobile terminal 200 corresponds to a smart phone possessed by a user. That is, each mobile terminal means one user, and N users transmit AP lists.

At this time, the user AP receiving unit 110 receives the list of APs from the plurality of mobile terminals 200, receives the list of APs from the plurality of indoor units 10 by the indoor unit AP receiving unit 160, To the processing unit 120. Of course, the AP processing unit 120 can receive the AP list from the AP storage unit storing the AP list of the plurality of indoor units 10. [

The AP processing unit 120 may calculate the similarity between each of the mobile terminals 200 and the plurality of indoor units 10. For example, the degree of similarity between the first mobile terminal 210 and the first indoor unit 11 and between the second indoor unit 12 and the Nth indoor unit 19 is calculated, The second indoor unit 12 and the Nth indoor unit 19 and calculates the degree of similarity of the first indoor unit 11 and the second indoor unit 12 to the Nth indoor unit 19. The Nth mobile terminal 280 and the first indoor unit 11, And calculates the degree of similarity between the indoor unit (12) and the Nth indoor unit (18).

The indoor unit determination unit 130 may determine the indoor unit 10 positioned adjacent to each mobile terminal 100. [ That is, the user and the indoor unit can be matched with each other.

Accordingly, the indoor unit controller 140 can operate the plurality of indoor units 10 in different modes. For example, the indoor unit 10 in which the adjacent mobile terminal 200 is not present can be controlled to be in an OFF or power saving mode. In addition, the indoor unit control unit 140 can control the indoor units, which are positioned adjacent to each other, in a rapid mode with the indoor unit having a preset reference value larger than a predetermined reference.

FIG. 7 is a view schematically showing an operation state of an air conditioning system according to another embodiment of the present invention. FIG. 7 shows a case where a plurality of users exist in FIG. 4, and the contents described above are cited. The positions of the plurality of users are arbitrarily specified for convenience of explanation.

7, the user exists only in the first chamber 300, the third chamber 320, the seventh chamber 360 and the eighth chamber 370, and the second chamber 310, There are no users in the fourth room 330, the fifth room 340, and the sixth room 350. At this time, unnecessary energy is wasted by operating the indoor units of all the rooms.

It is determined whether each user is located adjacent to which indoor unit through the above-described process. In detail, it is determined that the first user U1 is adjacent to the first indoor unit 11 and the second to seventh users U2, U3, U4, U5, U6, U7 are connected to the third indoor unit 13 And determines that the eighth and ninth users U8 and U9 are adjacent to the seventh indoor unit 17 and that the tenth user U10 is adjacent to the eighth indoor unit 18 Can be determined.

Accordingly, the indoor unit controller 140 can drive the first indoor unit 11, the third indoor unit 13, the seventh indoor unit 17, and the eighth indoor unit 18 in which adjacent users are present. In particular, the third indoor unit 13 in which a large number of adjacent users are present can be driven by a rapid operation. At this time, rapid operation means cooling or heating at a lower temperature, or operation with strong wind.

In addition, the indoor unit controller 140 may turn off the power of the second indoor unit 12, the fourth indoor unit 14, the fifth indoor unit 15, and the sixth indoor unit 16, .

With this control, the indoor unit can be more effectively controlled to provide convenience to the user, while energy can be saved.
