As shown in FIG. 3 , a system for controlling a plurality of air conditioners, the system comprising: one or more temperature sensors 200 installed in each of one or more zones; a plurality of controllers 300 for controlling each of a plurality of air conditioners installed in each of the one or more zones; one or more repeaters 400 for receiving temperature information from the temperature sensor 200 and transmitting air conditioner control information to the controller 300; and a service server 100 communicating with the repeater 400, wherein the service server 100 is a first air conditioner capable of operating with a preset output for each of the plurality of air conditioners for a preset time. a first air conditioner control information transmitting step of transmitting control information to the controller 300 through the repeater 400 (S10); a zone temperature information deriving step (S11) of deriving zone temperature information for each of the one or more zones based on the temperature information received from the one or more temperature sensors 200 installed in each of the one or more zones for the preset time; an operation priority determining step (S12) of determining an operation priority of a plurality of air conditioners installed in each of the one or more zones based on the zone temperature information; And based on the set temperature information for each of the one or more zones, the current zone temperature information for each of the one or more zones, and the operation priority of the plurality of air conditioners for each of the one or more zones Deriving second air conditioning control information, A second air conditioner control information transmission step (S13) of transmitting the second air conditioner control information to the controller 300 through the repeater 400 may be performed.

Specifically, the first air conditioner control information derived in the first air conditioner control information transmission step S10 enables each of the plurality of air conditioners corresponding to the corresponding zone to operate with a preset output for a preset time. More specifically, the first air conditioner control information enables only a specific air conditioner among a plurality of air conditioners corresponding to the corresponding zone to operate with a preset output for a preset time, and only other specific air conditioners from among the plurality of air conditioners after the preset time By enabling operation with a preset output for a preset time, as a result, each of the plurality of air conditioners corresponding to the corresponding zone can be operated independently. Accordingly, the first air conditioner control information controls all of the plurality of air conditioners corresponding to the corresponding zone to sequentially operate with a preset output for a preset time.

Meanwhile, the preset output may correspond to a specific output value that can be output from the air conditioner, but preferably, the preset output may correspond to a maximum output that can be output from the corresponding air conditioner.

In the zone temperature information deriving step (S11), the zone temperature information of the corresponding zone for the preset time for each air conditioner operated by the first air conditioner information derived in the first air conditioner control information transmission step (S10) is obtained. derive More specifically, the zone temperature information derivation step S11 derives zone temperature information of the corresponding zone that is changed by each air conditioner operated for a predetermined time according to the first air conditioner control information. Accordingly, in the zone temperature information deriving step S11, zone temperature information of the corresponding zone for the preset time for each air conditioner operated by the first air conditioner control information may be derived.

On the other hand, in the zone temperature information deriving step (S11), the zone temperature information of the zone is derived in real time or periodically for a preset time in order to derive zone temperature information of the zone for a preset time, or the zone temperature information of the zone is derived for a preset time. It is also possible to derive only the zone temperature information for each of the first and last time points.

In the operation priority determining step ( S12 ), cooling or heating performance is measured for each of a plurality of air conditioners corresponding to a corresponding zone, and an operation priority for each air conditioner is determined. Therefore, in the operation prioritization step (S12), the amount of change in the zone temperature information of the corresponding zone is calculated for a preset time operated by the first air conditioner control information for each air conditioner, and the change amount is the largest, preferably the The operation priority of each air conditioner may be determined in the order of the greatest absolute value of a value obtained by subtracting the zone temperature information at the last point of the preset time from the zone temperature information at the first point in time of the preset time.

The above-described first air conditioner control information transmission step (S10), zone temperature information derivation step (S11), and operation priority determination step (S12) are performed when the system for controlling a plurality of air conditioners of the present invention is first installed in a zone Although this is preferable, in another embodiment of the present invention, the corresponding steps are performed even after the initial installation, so that the operation priority for each zone may be updated in consideration of the different cooling or heating performance as each air conditioner deteriorates.

In the second air conditioner control information transmission step (S13), the second air conditioner control information is derived based on the set temperature information for the corresponding zone, the current zone temperature information of the corresponding zone and the operation priority for the corresponding zone, and the second air conditioner control information is derived. 2The air conditioner control information is transmitted to the controller 300 that controls the corresponding air conditioner through the repeater 400 . The second air conditioner control information operates the air conditioner having the highest operation priority with a preset output for a preset time, and compares the set temperature information with the zone temperature information at the time after the preset time has elapsed. Decrease the output of the air conditioner, or allow another air conditioner of lower priority to operate.

As described above, the second air conditioner control information controls the air conditioners to operate in the order in which the cooling or heating performance is excellent, so that the zone temperature information of the corresponding zone is lowered up to the set temperature information. Or heating can be performed.

As shown in (A) of FIG. 4 , the area temperature information deriving step S11 is received from the single temperature sensor 200 when a single temperature sensor 200 is installed in the corresponding area. When two or more temperature sensors 200 are installed in the corresponding zone, the representative of the two or more temperature information received from each of the two or more temperature sensors 200. The value can be derived as the zone temperature information for the zone.

Specifically, the zone temperature information derivation step (S11) includes, in addition to deriving the zone temperature information of the corresponding zone for a preset time operated by the first air conditioner control information, the corresponding method for deriving the second air conditioning control information Zone temperature information for each zone may be derived in real time or according to a preset period based on temperature information sensed by one or more temperature sensors 200 arranged for each zone, such as zone temperature information of each zone.

In addition, in the zone temperature information derivation step (S11), when there is one temperature sensor 200 disposed in the zone, the temperature information sensed by the temperature sensor 200 is derived as zone temperature information of the zone, and When there are two or more temperature sensors 200 disposed in a zone, the representative value of two or more temperature information sensed by the corresponding temperature sensor 200 is used to derive zone temperature information of the zone. In addition, the representative values of two or more temperature information may correspond to various statistical values representing a plurality of pieces of information. For example, the representative value may correspond to an arithmetic mean value, a median value, a geometric mean value, and a harmonic mean value for two or more temperature information.

Meanwhile, as shown in FIG. 4A , each of the air conditioners controlled by the controllers A to C may operate with a preset output for a preset time according to the first air conditioner control information, and each air conditioner According to the operation by the first air conditioner control information, the zone temperature of the corresponding zone for a preset time may change, and a graph of this trend is shown in FIG. 4B .

As shown in FIG. 4B, the operation prioritization step (S12) calculates the amount of change in the zone temperature information for the predetermined time for each of the plurality of air conditioners installed in each zone, The operation priority of the plurality of air conditioners for the corresponding area may be determined in the order of the largest change amount.

Specifically, as shown in FIG. 4B , the three air conditioners arranged in the corresponding area operate based on the first air conditioner control information transmitted from the controllers A to C, respectively, and preferably, each air conditioner is individually operated. By operating at maximum output for the set time (T _test ), it is possible to lower the zone temperature of the corresponding zone. Meanwhile, in FIG. 4(B) , the zone temperature of the corresponding zone is lowered according to the operation of each air conditioner, but when each air conditioner performs heating, the zone temperature may be increased by the operation of the air conditioner, Hereinafter, for ease of explanation, description will be made based on a case in which each air conditioner performs cooling.

Meanwhile, each air conditioner may have a different amount of change of zone temperature information for a _{preset time T test according to cooling performance.} For example, as shown in (B) of FIG. 4 , the air conditioner controlled by the controller A among the three air conditioners controlled by each of the controllers A to C is the amount of change of the zone temperature information during the _{preset time (T test )} is the smallest, it can be determined that the corresponding air conditioner has the lowest cooling performance, and since the air conditioner controlled by controller B has the largest change in zone temperature information during the _{preset time (T test ), the corresponding air conditioner has the cooling performance} This can be considered the highest.

FIG. 4C corresponds to a diagram schematically illustrating an operation priority in a corresponding zone according to the cooling performance of each air conditioner according to an embodiment of the present invention. As described in (B) of FIG. 4 , the operation priority for the corresponding zone may be determined in the order in which the amount of change of the zone temperature information during the _{preset time T test is greatest, that is, the cooling performance is the best.} Accordingly, the air conditioner controlled by the controller B may be determined as the first priority, and the air conditioner controlled by the controller A may be determined as the third priority.

Meanwhile, in FIG. 4 (A) to (C), the process of determining the operation priority for a plurality of air conditioners included in the zone is illustrated, but the operation priority determining step (S12) is included in the zone. Including a plurality of air conditioners and one or more air conditioners included in other zones affecting the zone, it is possible to determine the operation priority for the corresponding zone, group the plurality of air conditioners into 2 or more, and set the operation priority for each group. may decide This will be described in detail with reference to FIG. 6 .

In another embodiment of the present invention, when each of the plurality of air conditioners operates with a preset output for a preset time according to the first air conditioner control information, a predetermined waiting time may be given between the operations of each air conditioner. Therefore, since the air conditioner is not operated during the waiting time, the temperature of the corresponding area being cooled is increased to a certain degree or the temperature of the corresponding area being heated is lowered to a certain degree, so each air conditioner operates according to the first air conditioner control information. By maintaining the temperature of the corresponding area at the time point constant, it is possible to exert the effect of more accurately calculating the cooling or heating performance of each air conditioner.

5 schematically illustrates operation processes of a plurality of air conditioners in a corresponding area according to second air conditioner control information according to an embodiment of the present invention.

As shown in FIG. 5 , the second air conditioner control information derived in the second air conditioner control information transmission step S13 is the first air conditioner having the highest first priority with respect to the corresponding area for a predetermined first time period. It operates at this maximum output, and when the zone temperature information of the corresponding zone is less than or equal to the set temperature information of the zone after the first time, it is possible to control the output of the first air conditioner to decrease.

Specifically, when the second air conditioner control information transmitter 140 receives the set temperature information for the corresponding zone from the user terminal 500, the set temperature information for the corresponding zone, the current zone temperature information of the corresponding zone, and the corresponding Based on the operation priority determined for the zone, the second air conditioner control information is derived. Thereafter, the second air conditioning control information transmitter 140 transmits the second air conditioning control information to the plurality of controllers 300 through one or more repeaters 400 that can transmit information to the plurality of controllers 300 corresponding to the corresponding zone 300) may transmit the second air conditioner control information (S20).

According to the result of operation according to the control information, separate second air conditioner control information for transmission to the corresponding air conditioner or one or more other air conditioners may be derived and transmitted to the corresponding controller 300 .

On the other hand, the controller 300 for controlling the first air conditioner having the highest operation priority that has received the second air conditioner control information operates the first air conditioner at maximum output for a first time based on the second air conditioner control information. control (S21). In the corresponding step, one or more other air conditioners corresponding to the corresponding area do not operate, and only the first air conditioner may operate at maximum output for the first time.

Thereafter, the service server 100, preferably the second air conditioner control information transmitting unit 140, compares the zone temperature information of the corresponding zone at the time when the first time has elapsed and the set temperature information of the corresponding zone (S22). )do. On the other hand, the zone temperature information of the corresponding zone at the time when the first time has elapsed is obtained from one or more temperature sensors 200 disposed in the corresponding zone at the time when the first time has elapsed in the zone temperature information derivation step (S11). It may be derived based on one or more sensed temperature information.

When the set temperature information in step S22 is equal to or higher than the zone temperature information at the time when the first air conditioner completes the operation for the first time, the second air conditioner control information has the highest operation priority It is possible to control (S23) to decrease the output of the first air conditioner.

In another embodiment of the present invention, in the second air conditioner control information transmitting unit 140, the set temperature information in step S22 is the same as the zone temperature information at the time when the first air conditioner completes the operation for the first time. or high, separate second air conditioner control information for controlling to decrease the output of the first air conditioner may be derived and transmitted to the controller 300 for controlling the first air conditioner.

Meanwhile, although not shown in FIG. 5 , the second air conditioner control information performs the step S23, and the second air conditioner control information transmitter 140 performs the step S22 after a predetermined time has elapsed, and the set temperature information When is equal to or higher than the zone temperature information at the time point, the second air conditioner control information may additionally reduce the output of the first air conditioner, and when the set temperature information is lower than the zone temperature information at the time point The second air conditioner control information may perform the step S21 or may perform the step S24 to be described later.

On the other hand, the second air conditioner control information derived in the second air conditioner control information transmitting step (S13) is such that the first air conditioner having the highest first priority for the corresponding area for a predetermined first time operates at maximum output. and, when the zone temperature information of the corresponding zone exceeds the set temperature information of the zone after the first time, one or more other air conditioners having a lower priority than the first priority for the zone are set to a predetermined control. It can be controlled to operate additionally for 2 hours.

Specifically, in the above-described step S22, when the set temperature information is lower than the zone temperature information at the time when the first air conditioner completes the operation for the first time, the second air conditioner control information is The first air conditioner having a high operation priority and one or more other air conditioners having a lower operation priority are controlled to additionally operate for a predetermined second time (S24).

On the other hand, the one or more other air conditioners having the lower operation priority correspond to the air conditioners immediately below the highest operation priority or two or more air conditioners corresponding to two or more orders less than the highest operation priority. may correspond to, and the first air conditioner and one or more other air conditioners having a lower operation priority may operate at a predetermined output for a second time, and preferably operate at a maximum output during the second time. there is.

Thereafter, the second air conditioner control information transmitting unit 140 compares (S25) the zone temperature information of the corresponding zone and the set temperature information of the corresponding zone at the time when the second time has elapsed. Similarly, the zone temperature information of the zone at the time when the second time has elapsed is sensed by one or more temperature sensors 200 disposed in the zone at the time when the second time has elapsed in the zone temperature information derivation step (S11). It may be derived based on one or more temperature information.

On the other hand, when the set temperature information is equal to or higher than the zone temperature information at the time when the first air conditioner and the one or more other air conditioners complete the operation for the second time in the step S25, the second air conditioner is controlled The information may be controlled to decrease the output of the first air conditioner and the one or more other air conditioners that have operated (S26).

In another embodiment of the present invention, the second air conditioner control information transmitter 140 receives the set temperature information in step S25 when the first air conditioner and the one or more other air conditioners complete the operation for the second time. When it is equal to or higher than the zone temperature information of It may be transmitted to a plurality of controllers 300 that control the air conditioner.

On the other hand, when the set temperature information is lower than the zone temperature information at the time when the first air conditioner and the one or more other air conditioners complete the operation for the second time in the above-described step S25, the second air conditioner control information may control all the plurality of air conditioners corresponding to the corresponding zone to operate at a predetermined output, preferably, the maximum output for the third time (S27).

By outputting it, it is possible to display the effect of quickly lowering the zone temperature information of the corresponding zone corresponding to the set temperature information while optimizing the power consumption according to cooling.

Meanwhile, in another embodiment of the present invention, the second air conditioner control information may control a plurality of air conditioners corresponding to each zone to perform heating of the corresponding zone. In this case, as described with reference to FIG. 5, the operation of the plurality of air conditioners corresponding to the corresponding zone is controlled, but when the set temperature information in steps S22 and S25 is equal to or lower than the zone temperature information at the time point The second air conditioner control information controls the output of one or more air conditioners that have been operated to decrease, and when the set temperature information in steps S22 and S25 is higher than the zone temperature information at the time, the second air conditioner The control information may control one or more other air conditioners having a lower operation priority than the one or more air conditioners that have been operated to additionally operate.

It can be derived from the transmitter 140 . More specifically, when the set temperature information is higher than the current zone temperature information, the second air conditioning control information transmitting unit 140 derives second air conditioning control information for heating, and the set temperature information is the current zone temperature When it is lower than the information, the second air conditioner control information transmitter 140 may derive the second air conditioner control information for cooling.

A plurality of air conditioners including two or more air conditioners by deriving the first air conditioner control information, and in the operation prioritization step (S12), considering the change amount of zone temperature information for each of the plurality of air conditioners for a preset time can be grouped into groups of For example, in the operation prioritization step (S12), the air conditioner having the highest cooling performance and the air conditioner having the next highest cooling performance are grouped into one group, and the air conditioners corresponding to the next two priorities are grouped into another group. It can also be grouped in such a way as to
