The air conditioning system is a system for maintaining the air in a predetermined space in the most suitable state according to the purpose and purpose. In general, an air conditioning system includes a compressor, a condenser, an expansion device, and an evaporator, and a refrigerant cycle performing compression, condensation, expansion and evaporation of the refrigerant is driven to cool or heat the predetermined space.

In this case, the predetermined space may be variously proposed according to a place where the air conditioning system is used. For example, when the air conditioning system is used in a home or office, the predetermined space may be an indoor space of a house or a building. Also, when the air conditioning system is used in a vehicle, the predetermined space may be a boarding space in which a person boards.

Recently, a technology for automatically controlling the air conditioning system by judging the existence of a user who needs air conditioned in the predetermined space has been developed. Prior literature information related to this technology is as follows.

(2) 2nd prior document: Registered Patent 10-1470540, air conditioner and its control method.

These prior documents require a separate sensing device, such as an infrared sensor, to determine the presence or absence of a user. Such a sensing device has a problem in that it is difficult to accurately determine the presence or absence of a user. For example, in the case of the infrared sensor, it is possible to recognize a non-human animal, a device that emits heat, and the like.

In addition, these sensing devices correspond to very expensive equipment. Accordingly, there is a problem in that price competitiveness is lowered when a separate device is provided. In addition, there is a problem in that the reliability of such a sensing device is not ensured and replacement is required because it has a lifespan.

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

In addition, the present invention provides an air conditioning system and a control method for efficiently balancing a predetermined space by determining whether a user is present in a place adjacent to an indoor unit and controlling the power saving operation or rapid operation to be performed.

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

The AP processing unit may calculate the similarity by using the Euclidean distance.

The AP processing unit calculates the similarity between the mobile terminal and each indoor period by squaring the difference in signal strength when there is a corresponding AP, and summing the squared value of the difference in signal strength when there is no corresponding AP. can

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

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

The control unit may further include an indoor unit controller configured to control each of the plurality of indoor units, and the indoor unit controller may control an indoor unit in which a mobile terminal located adjacent to each other is not present, in an OFF or power saving mode.

The control unit may further include an indoor unit controller configured to control each of the plurality of indoor units, and the indoor unit controller may control the indoor units in which the number of adjacent mobile terminals is greater than a predetermined criterion in a rapid mode.

In addition, in the control method of an air conditioning system according to the spirit of the present invention, in the control method of an air conditioning system provided with a plurality of indoor units installed at different positions, an AP list is received from a mobile terminal, and the received AP list is received. and an AP list corresponding to the locations where the plurality of indoor units are installed to calculate a similarity, determine an indoor unit adjacent to the mobile terminal according to the calculated similarity, and operate the determined adjacent indoor unit.

An AP list corresponding to a location where the plurality of indoor units are installed may be stored.

The AP list may be received from the plurality of indoor units, and a degree of similarity may be calculated by comparing the AP list with the AP list received from the mobile terminal.

The similarity of 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 may be calculated using the Euclidean distance.

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

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

1, in the air conditioning system according to the spirit of the present invention, a plurality of indoor units 10, at least one outdoor unit 20, and a control unit for controlling the indoor unit 10 and the outdoor unit 20 ( 100) is included.

In FIG. 1 , the connection between the indoor unit 10 , the outdoor unit 20 , and the control unit 100 is schematically illustrated.

The indoor unit 10 and the outdoor unit 20 may be connected through a refrigerant pipe so that a refrigerant flows and a refrigerant cycle is formed. In addition, a distributor may be provided such that a plurality of indoor units 10 are connected to one outdoor unit 20 to be driven. As such a configuration is used in a general air conditioning system, 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 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 connected to the indoor unit 10 and the outdoor unit 20 in various ways. For example, the control unit 100 may be respectively connected to the indoor unit 10 and the outdoor unit 20 . Also, 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 to be connected to each other.

Although one outdoor unit 20 is illustrated in FIG. 1 , this is exemplary and a plurality of outdoor units 20 may also be provided. In addition, although the shape of the indoor unit 10 is illustrated as a ceiling-type indoor unit in FIG. 1 , this is illustrative. can

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

The present invention relates to the plurality of indoor units 10 and the control unit 100 for controlling the plurality of indoor units 10, and details 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 diagram showing the configuration of an air conditioning system according to an embodiment of the present invention.

As shown in Figure 2, the control unit 100 is provided with various configurations. For convenience of description, only the components related to the features of the present invention are shown and described, and the remaining components are omitted. In addition, the plurality of indoor units 10 includes a first indoor unit 11 and a second indoor unit 12 to an N-th indoor unit 18 .

The control unit 100 is provided with an AP (Access Point) signal detection module 200a provided with a user AP receiving unit 110 to receive the AP list from the mobile terminal 200 is provided.

The mobile terminal 200 includes a smartphone possessed by the user. In addition, the AP signal detection module 200a means a Wi-Fi detection function provided in the smartphone. That is, the AP list may be understood as a 'connectable Wi-Fi list' searched for by a smartphone.

In addition, such a 'connectable Wi-Fi list' may be searched by the smart phone itself even when the user does not use the Wi-Fi function in the mobile terminal 200 and may not require a user's action.

The AP list may include a plurality of APs and signal strengths of each AP. AP means a router, etc. installed arbitrarily in each place. For example, these APs are installed in one room at least 6, at most 45. In particular, more APs may be installed in an environment in which smartphones and the like become daily life.

Such an AP does not correspond to one configuration of the air conditioning system of the present invention, and the present invention merely uses an AP that is generally installed.

In addition, although the mobile terminal 200 is illustrated in FIG. 2 for convenience of explanation, the mobile terminal 200 does not correspond to one configuration of the air conditioning system. That is, the mobile terminal 200 corresponds to an example of a device that transmits predetermined information to the user AP receiver 110 .

The mobile terminal 200 may be set to transmit the AP list to the user AP receiver 110 at predetermined time intervals. In this case, the mobile terminal 200 may transmit the AP list at the time of transmission to the user AP receiver 110 .

In addition, in FIG. 2 , only the mobile terminal 200 transmits predetermined information to the user AP receiver 110 , but the user AP receiver 110 requests information from the mobile terminal 200 . may be arranged to transmit. Accordingly, when the user AP receiving unit 110 requests, the mobile terminal 200 may transmit the AP list at that time to the user AP receiving unit 110 .

In addition, in the control unit 100, the AP processing unit 120 for calculating the similarity by comparing the AP list received by the user AP receiver 110 with the AP list corresponding to the location where the plurality of indoor units 10 are installed. is provided In this case, 'similarity' is a measure indicating the degree of similarity between AP lists, and the calculation method will be described later.

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

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

The AP storage unit 150 stores an AP list of locations 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 position in the AP storage unit 150 using a smart phone or the like.

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

The AP processing unit 120 may calculate the similarity by 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 between 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 . In addition, the Euclidean distances of the AP list received in the user AP receiver 110 and the AP list of the second indoor unit 12 to the Nth indoor unit 18 stored in the AP storage unit 150 are respectively calculated.

A detailed calculation method will be described later with reference to FIG. 5 .

In addition, the control unit 100 is provided with an indoor unit judging unit 130 for determining the 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 determining unit 130 may determine that the mobile terminal 200 is located adjacent to the corresponding indoor unit 10 when the value calculated by the AP processing unit 120 is smaller than a predetermined criterion. In this case, being adjacent to each other may be understood that the mobile terminal 200 is located in the sphere of influence of the indoor unit 10 .

The predetermined criterion may be determined as a predetermined value through an experiment. For example, when the indoor unit 10 is installed in each room, the range of the AP list generated when the mobile terminal 200 is located in the room where the indoor unit 10 is installed may be set. Based on the range of the AP list, a criterion for determining that the mobile terminal 200 is located in the room where the indoor unit 10 is installed can be calculated.

Through this, the indoor unit determination unit 130 may determine that the mobile terminal 200 is positioned adjacent to any one of the plurality of indoor units 10 .

In addition, the control unit 100 further includes an indoor unit controller 140 for controlling each of the plurality of indoor units 10 . The indoor unit control unit 140 may drive each indoor unit 10 according to a result determined by the indoor unit determination unit 130 .

For example, when it is determined by the indoor unit judging end unit 130 that the mobile terminal 200 is positioned adjacent to the first indoor unit 11, the indoor unit control unit 140 controls the first indoor unit ( 11) can be driven.

Also, as the user moves, the AP list of the mobile terminal 200 may be changed. Accordingly, the user AP receiving unit 110 receives the changed AP list and transmits it to the AP processing unit 120 , and the AP processing unit 120 restores the degree of similarity to the AP list stored in the AP storage unit 150 . Calculate.

Accordingly, when it is determined by the indoor unit judging end unit 130 that the mobile terminal 200 is positioned adjacent to the second indoor unit 12 , the indoor unit control unit 140 controls the first indoor unit 11 . ) may be stopped and the second indoor unit 12 may be driven.

Through this process, the control unit 100 may drive each indoor unit 10 according to the user's location.

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

In FIG. 3, each indoor unit 10 is provided with the AP signal detection module 11a, 12a, 18a, and the control unit 100 is provided with the AP receiver 160 instead of the AP storage unit 150 described above. is shown for The description of the configuration described in FIG. 2 is omitted and the above content is cited.

The first indoor unit 11 to the N-th indoor unit 18 are provided with AP signal detection modules 11a, 12a, and 18a, respectively. As described above, the AP signal detection modules 11a, 12a, and 18a can be understood as a kind of communication module that means a Wi-Fi detection function.

Each AP signal detection module 11a, 12a, 18a does not need to be directly installed in each indoor unit 10, but it is sufficient to be installed in a space in which each indoor unit 10 is installed. For example, an AP signal detection module disposed in a space in which each indoor unit 10 is installed may be used.

The indoor unit AP receiver 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 AP list received by the user AP receiving unit 110 with the AP list 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 once stored AP list. 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 drive the indoor unit 10 .

4 is a diagram schematically illustrating an operating 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. 4 and 5 exemplarily show the operation by the above-described configuration.

4 illustrates an exemplary situation in which the plurality of indoor units 10 are installed. In detail, a space provided with eight rooms in which the indoor unit 10 is installed is shown.

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 ( 350), the seventh chamber 360 and the eighth chamber 370 are divided. In addition, a passage is provided between the first chamber 300 to the fourth chamber 330 and the fifth chamber 340 to the eighth chamber 370 .

The plurality of indoor units 10 are provided 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 , and the second indoor unit 12 installed in the second room 310 . The third indoor unit 13 installed in the third room 320, the fourth indoor unit 14 installed in the fourth room 330, the fifth indoor unit 15 installed in the fifth room 340, the The sixth indoor unit 16 installed in the sixth room 350 , the seventh indoor unit 17 installed in the seventh room 360 , and the eighth indoor unit 18 installed in the eighth room 370 are provided. Included.

That is, it is assumed in FIG. 2 that the N-th 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 .

In addition, FIG. 4 shows a plurality of arbitrarily installed APs. For convenience of explanation, it is shown that six APs are installed in arbitrary positions. In general, a larger number of APs are installed, and may be installed in each room for user convenience. Accordingly, the accuracy of the results according to the present invention can be higher.

FIG. 5 shows an AP list by way of example, which is arbitrarily prepared for convenience of description and has nothing to do with reality. 5A is a list of APs searched for in the user's mobile terminal 200 .

For example, when a user (U, USER) holding the mobile terminal 200 exists in the seventh room 360 as shown in FIG. 4 , A disposed in the seventh room 360 has the strongest signal strength. , and B may have the next strongest signal strength. In addition, the signal of distant E may not be picked up. Accordingly, the AP list as shown in (a) of FIG. 5 can be searched for in the mobile terminal 200 .

In addition, FIGS. 5 ( b ) and 5 ( c ) show an AP list of any one of the plurality of indoor units 10 .

FIG. 5(b) is very similar to the AP list of the mobile terminal 200 shown in FIG. 5(a), and accordingly, FIG. It can be predicted by the indoor unit 17 . Also, in FIG. 5C , the signal F is the strongest and the signal C is not captured, so it can be predicted as the fifth indoor unit 15 installed in the fifth room 340 .

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

In detail, the AP processing unit 120, when there is a corresponding AP, squares the difference in its signal strength, and when there is no corresponding AP, adds the squared value of the difference in signal strength to the mobile terminal 200 ) and the degree of similarity between each indoor unit 10 may be calculated.

For example, the Euclidean distance between the AP list retrieved from the user's mobile terminal 200 and the AP list of the indoor unit 10 shown in FIG. 5B is calculated. At this time, since all APs correspond, the squared value of the signal strength difference of each AP is obtained.

In detail, the difference in signal strength corresponding to A is squared by 2, the difference in signal strength corresponding to B is squared by 6, the difference in signal strength corresponding to C is squared by 3, and the signal corresponding to D is squared. The difference in strength, 13, is squared, and 11, the difference in signal strength corresponding to E, is squared and added. If the value is obtained in this way, a value of 339 can be obtained.

In addition, the Euclidean distance between the AP list retrieved from the user's mobile terminal 200 and the AP list of the indoor unit 10 described in FIG. 5C is calculated. In this case, the corresponding APs are A, B, D, and E, which are obtained by squaring the signal strength difference of each AP, and non-corresponding APs C, F square the signal strength difference.

In detail, the difference in signal strength corresponding to A is squared by 36, the difference in signal strength corresponding to B is squared by 30, the difference in signal strength corresponding to D is squared by 31, and the signal corresponding to E is squared. Square the difference of intensities, 21, and add them. In addition, the signal strength of C is squared and the signal strength of F is squared and added. If the value is obtained in this way, a value of 13544 can be obtained.

According to the calculated value, the indoor unit judging unit 130 may find the indoor unit 10 adjacent to the mobile terminal 200 .

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

As described above, the mobile terminal 200 corresponds to a smartphone possessed by the user. That is, each mobile terminal means one user, and shows a case in which N users transmit an AP list.

At this time, the user AP receiving unit 110 receives each AP list from the plurality of mobile terminals 200 , and receives each AP list from the plurality of indoor units 10 through the indoor unit AP receiving unit 160 . may be transmitted to the processing unit 120 . Of course, the AP processing unit 120 may 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 a degree of similarity between each mobile terminal 200 and the plurality of indoor units 10 . For example, the similarity between the first mobile terminal 210, the first indoor unit 11, and the second indoor unit 12 to the N-th indoor unit 19 is calculated, and the second mobile terminal 220 and the degree of similarity between the first indoor unit 11, the second indoor unit 12 to the N-th indoor unit 19 is calculated, and the N-th mobile terminal 280, the first indoor unit 11, and the second indoor unit The degree of similarity between the indoor unit 12 to the N-th indoor unit 18 is calculated.
