With the continuous development of building informatization technology, the multi-split system has the requirements such as partition management, fault diagnosis, indoor positioning and the like. However, due to the lack of the correspondence between the mounting positions and the digital codes, many techniques are difficult to apply in a floor-standing manner. For example, for the partition management technology, although about 30% of operation energy saving can be realized, as different indoor units are distinguished at the cloud only through digital codes, the accurate installation positions of the indoor units cannot be determined, so that cloud centralized control is difficult to develop; for the fault diagnosis technology, the cloud can achieve fault prediction accuracy of more than 95%, but when the fault is reported to operation and maintenance personnel, the operation and maintenance personnel can only know the digital codes of the fault indoor units and cannot know the specific installation positions of the fault indoor units in the whole building, so that the maintenance time is greatly prolonged.
Although the installation position and the digital code of the indoor unit of the multi-split system can be matched manually in the related technology, the manual matching method needs to consume a great deal of manpower and material resources, and cannot realize automatic matching of the installation position and the digital code of the indoor unit of the multi-split system.

Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
In order to clearly illustrate the indoor unit location recognition method, the device, the electronic equipment and the medium according to the embodiments of the present invention, the following description is made with reference to a flowchart of the indoor unit location recognition method shown in fig. 1. As shown in fig. 1, the indoor unit location identifying method in the embodiment of the present application includes the following steps:
S11: acquiring system parameters of a multi-split system and acquiring a building design drawing;
s13: determining digital coding distribution information, peripheral coefficients and association degree information of each indoor unit according to system parameters, and determining installation position distribution information of each indoor unit according to a building design drawing;
s15: and carrying out multiple matching according to the digital code distribution information, the peripheral coefficient, the association degree information and the installation position distribution information, and establishing a matching relationship between the digital code and the installation position of each indoor unit.
According to the indoor unit position identification method provided by the embodiment of the invention, the installation position and the digital code of the indoor unit can be automatically matched, so that the labor matching cost is reduced. And after the installation position of the indoor unit is matched with the digital code, the indoor unit is convenient to carry out partition management on the cloud end, and meanwhile, when the indoor unit fails, a maintainer can quickly determine the installation position of the failed indoor unit according to the failure data, so that the failed indoor unit can be timely maintained, and the maintenance time is shortened.
Specifically, the multi-split system may include a central air conditioning system. The multi-connected air conditioner system can comprise an outdoor unit and a plurality of indoor units, wherein each indoor unit comprises a digital code, and the digital codes of the indoor units are different from each other, so that different indoor units are represented by the digital codes in the communication process. The positions of the outdoor units are usually fixed and easy to identify, and the indoor units are large in number and wide in distribution, and when the indoor units are monitored to be faulty, only the digital codes corresponding to the faulty indoor units can be determined, but the mounting positions corresponding to the faulty indoor units cannot be determined, so that the faulty indoor units are not beneficial to being quickly maintained, and therefore, the mounting positions and the digital codes of each indoor unit need to be matched in advance.
The system parameters may include time, outdoor temperature, evaporating temperature of each indoor unit, digital code, first indoor unit type, first affiliated refrigerant system, operation mode, first indoor unit number, return air temperature and set temperature.
After the system parameters are acquired, data alignment can be performed on a plurality of data in the system parameters according to time, so that the accuracy of the installation positions and the digital codes of the matched indoor units can be improved. It can be understood that the indoor units in the same refrigerant system generally have the same operation mode, and by comparing the operation modes of the plurality of indoor units in the system parameters, it can be verified whether the plurality of indoor units are in the same refrigerant system. The digital code can be understood as the virtual ID number of the indoor unit. The numerical code may be one or more of a number, letter, symbol. In one example, the number codes of the plurality of indoor units are 1#, 2#, 3#, and 4# in sequence. The set temperature may be understood as a temperature at which each indoor unit is individually set by a user. In some embodiments, the system parameters may further include a refrigerant temperature change, which is equivalent to the evaporation temperature, and the refrigerant temperature change is the evaporation temperature change.
The building design drawing can be a CAD plan, and the building design drawing can be marked with inner wall information, envelope information, inner machine icons of each indoor machine, installation positions, icon marks and the like. In one example, the installation location may be denoted A, B, C, D, etc. The building envelope information may be understood as the exterior walls of the building. It can be appreciated that by identifying the outer wall label and the inner wall label in the architectural design drawing, the outer wall position and the inner wall position can be determined, thereby facilitating the determination of the indoor areas of the plurality of indoor units according to the outer wall and the inner wall. In some embodiments, the building design drawing further comprises region labels, such as office area labels, conference area labels, printing area labels, corridor labels and rest area labels, so that the region where the indoor unit is located indoors can be rapidly determined according to the building design drawing.
The peripheral coefficient can be understood as the probability that the indoor unit is close to the enclosure. The larger the peripheral coefficient is, the closer the indoor unit is to the enclosure structure; the smaller the peripheral coefficient is, the farther the indoor unit is from the enclosure structure.
The correlation degree information can be understood as the degree of interaction between every two indoor units. The association degree information of one indoor unit may include the interaction degree of the one indoor unit and any other indoor unit. The degree of interaction may be expressed in numerical form. In the same closed environment, the closer the two indoor units are, the more serious the degree of interaction of the two indoor units is, and accordingly, the larger the numerical value of the degree of interaction of the two indoor units is.
In some embodiments of the present invention, determining the digital code distribution information of each indoor unit according to the system parameters in step S13 includes: and determining the digital coding distribution information of each indoor unit according to the digital codes of each indoor unit, the first indoor unit type, the first indoor unit number and the first affiliated refrigerant system in the system parameters.
Thus, the digital code distribution information comprises a first affiliated refrigerant system, a first internal machine number and a first internal machine type identification characteristic, and provides a basis for automatically matching the installation position and the digital code.
Specifically, in the digital code distribution information, one digital code corresponds to a first affiliated refrigerant system, a first internal machine number and a first internal machine type, and the first affiliated refrigerant system, the first internal machine number and the first internal machine type corresponding to different digital codes can be the same or different. The generated digital code distribution information can be transmitted and stored in a form of a table.
In one example, the digital code distribution information is shown in table 1, and it can be seen that the first refrigerant systems of the three indoor units with digital codes of # 1, # 3 and # 4 are all C1, the first indoor units have numbers of 1.5, and the first indoor units are all ceiling machines; the first refrigerant system of the indoor unit with the digital code of 2# is C1, the number of the first indoor units is 1, and the type of the first indoor units is a ceiling suspended machine; the first refrigerant systems of the two indoor units with the digital codes of 5# and 6# are C2, the number of the first indoor units is 2, and the types of the first indoor units are ceiling machines; the first refrigerant systems of the three indoor units with the digital codes of 7#, 8#, and 9# are all C2, the number of the first indoor units is 1, and the types of the first indoor units are all ceiling machines.

Referring to fig. 2, in some embodiments of the present invention, the system parameters include an outdoor temperature and a return air temperature of each indoor unit, and determining the peripheral coefficient of each indoor unit according to the system parameters in step S13 includes:
s21: respectively determining the difference value between the outdoor temperature and the return air temperature of each indoor unit;
s23: and determining the peripheral coefficient of each indoor unit according to the difference value and the preset corresponding relation.
In this way, the peripheral coefficient can be obtained by the outdoor temperature and the return air temperature.
Specifically, the difference may be obtained by subtracting the return air temperature from the outdoor temperature, or may be obtained by subtracting the return air temperature from the outdoor temperature, which is not limited herein. It should be noted that the difference between the return air temperature and the outdoor temperature of each indoor unit is calculated in a consistent manner.
The preset corresponding relation is the corresponding relation between the difference value and the peripheral coefficient. The peripheral coefficients can be calibrated in advance according to different differences, so that the corresponding relation between the differences and the peripheral coefficients is obtained. It can be appreciated that the closer the indoor unit is to the enclosure, the greater the correlation between the return air temperature and the indoor temperature, and the greater the peripheral coefficient. Because the system parameters do not include the distance between the indoor unit and the enclosure structure, the distance between the indoor unit and the enclosure structure cannot be directly determined according to the system parameters, the peripheral coefficient can be determined based on the correlation between the outdoor temperature and the return air temperature, and the probability that the indoor unit is close to the enclosure structure is further represented by the peripheral coefficient.
Referring to fig. 3, in some embodiments of the present invention, the system parameters include a return air temperature, an evaporation temperature, and a set temperature of each indoor unit, and determining the association degree information of each indoor unit according to the system parameters in step S13 includes:
s31: calculating first correlation coefficients of every two indoor units according to the evaporating temperature;
s33: calculating a second correlation coefficient of each two indoor units according to the return air temperature;
s35: calculating a third correlation coefficient of each two indoor units according to the set temperature;
s37: and carrying out weighted summation on the first correlation coefficient, the second correlation coefficient and the third correlation coefficient to determine the association degree information of each indoor unit.
Thus, accurate association degree information among different indoor units can be obtained. It will be appreciated that, considering that the indoor units are devices for adjusting the temperature in the sealed environment, the indoor units having an effect share one sealed environment, and thus the obtained return air temperature, evaporation temperature and set temperature of the indoor units can be used to extract the effect.
In some embodiments, determining a first covariance of an evaporating temperature of one of each of the two indoor units and an evaporating temperature of the other of each of the two indoor units; determining a first variance value of the evaporating temperature of one indoor unit in every two indoor units; determining a second variance value of the evaporating temperature of the other indoor unit in every two indoor units; a first correlation coefficient is calculated based on the first covariance, the first variance value, and the second variance value. In one example, a first correlation coefficient r 1 The calculation formula of (J, K) is as follows:
wherein J represents one indoor unit of every two indoor units, K represents the other indoor unit of every two indoor units, cov 1 (J, K) represents the first covariance, var 1 [J]Representing a first variance value Var 1 [K]Representing a second variance value.
In some embodiments, a second covariance of the return air temperature of one of the two indoor units and the return air temperature of the other of the two indoor units is determinedThe method comprises the steps of carrying out a first treatment on the surface of the Determining a third deviation value of the return air temperature of one indoor unit in every two indoor units; determining a fourth difference value of the return air temperature of the other indoor unit in every two indoor units; and calculating a second correlation coefficient according to the second covariance, the third variance value and the fourth variance value. In one example, the second correlation coefficient r 2 The calculation formula of (J, K) is as follows:
wherein J represents one indoor unit of every two indoor units, K represents the other indoor unit of every two indoor units, cov 2 (J, K) represents a second covariance, var 2 [J]Representing a third difference value Var 2 [K]Representing a fourth difference value.
In some embodiments, determining a third covariance of the set temperature of one of the two indoor units and the set temperature of the other of the two indoor units; determining a fifth variance value of the set temperature of one indoor unit in every two indoor units; determining a sixth variance value of the set temperature of the other indoor unit in every two indoor units; and calculating a third correlation coefficient according to the third covariance, the fifth variance value and the sixth variance value. In one example, a third correlation coefficient r 3 The calculation formula of (J, K) is as follows:
wherein J represents one indoor unit of every two indoor units, K represents the other indoor unit of every two indoor units, cov 3 (J, K) represents a third covariance, var 3 [J]Represents a fifth variance value Var 3 [K]Representing a sixth variance value.
In one example, the association degree information R of each indoor unit may be expressed by the following formula: r=a×r 1 (J,K)+b*r 2 (J,K)+c*r 3 (J, K), wherein a is the weight of the first correlation coefficient, b is the weight of the second correlation coefficient, and c is the weight of the third correlation coefficient. a. b and c can be set as required.
Referring to fig. 4, in some embodiments of the present invention, a building design drawing includes an enclosure structure, indoor units, an indoor unit connection pipeline, an indoor unit icon and an icon label, and determining installation position distribution information of each indoor unit according to the building design drawing in step S13 includes:
s41: identifying an indoor unit icon to determine the installation position and the second indoor unit type of each indoor unit;
s43: identifying icon labels to determine the second number of indoor units of each indoor unit;

s47: determining the coordinates of the indoor unit and the coordinates of the enclosure structure, and determining the distance from the indoor unit to the enclosure structure according to the coordinates of the indoor unit and the coordinates of the enclosure structure;
S49: and determining the installation position distribution information of each indoor unit according to the installation position of each indoor unit, the type of the second indoor unit, the number of the second indoor units, the refrigerant system of the second indoor unit and the distance from the indoor unit to the enclosure structure.
Therefore, the second affiliated refrigerant system, the second indoor unit number, the second indoor unit type, the installation position and the distance from the indoor unit to the enclosure structure of each indoor unit can be determined through the image recognition technology.
Specifically, the architectural design drawing can be converted into a clear image in advance, and then used for image recognition. The second belonging refrigerant system, the second internal machine number, the second internal machine type and the installation position can be directly determined by identifying specific icons and marks in the image.
In step S47, the building design drawing may be two-dimensionally coordinated, and the envelope coordinates and the indoor unit coordinates may be identified by calculating the pixels of the building design drawing.
The same indoor unit may correspond to a plurality of pixels, one pixel corresponds to one coordinate, and thus the same indoor unit may correspond to a plurality of coordinates.
The enclosure structure also corresponds to a plurality of pixels, one pixel corresponds to one coordinate, and the enclosure structure can further correspond to a plurality of coordinates, and it is pointed out that the distance from the inner machine to the enclosure structure is the shortest distance between the inner machine and the enclosure structure, namely, the pixel coordinate of the enclosure structure closest to the coordinate of the inner machine is selected to calculate the distance.

In some embodiments, by performing image recognition on the architectural design drawing, it may also be determined whether the indoor unit is in an independent space. Independent space is understood to be a relatively enclosed area, such as a conference room, a booth, etc. The value of the association degree information between the indoor units located in the independent space and the indoor units located outside the independent space is low.
Referring to fig. 6, in some embodiments of the present invention, step S15 includes:
s151: performing first matching on the digital code distribution information and the installation position distribution information to obtain a first matching result;
s153: performing secondary matching on the digital coding distribution information and the installation position distribution information according to the peripheral coefficient and the first matching result to obtain a second matching result;
s155: and carrying out third matching on the digital code distribution information and the installation position distribution information according to the association degree information and the second matching result so as to obtain the matching relationship between the digital code and the installation position of each indoor unit.
Therefore, the installation positions and the digital codes of part of the indoor units in the plurality of indoor units are matched rapidly through the first matching and the second matching, so that the number of the indoor units to be matched in the third matching is reduced, the operand of the third matching is saved, and the overall matching speed is accelerated.
Specifically, the digital code distribution information includes a digital code of each indoor unit, excluding an installation position of each indoor unit. The installation position distribution information comprises the installation position of each indoor unit, and does not comprise the digital code of each indoor unit. The digital code distribution information and the installation position distribution information may simultaneously include at least one identification feature of the same indoor unit, so that a correspondence relationship between an installation position of a part of the indoor units and the digital code can be established by comparing the two kinds of distribution information in the first matching, and a rough indoor area of each indoor unit can be determined, and a first set of indoor units to be matched can be determined. In one example, after the first matching, it may be determined that the indoor unit corresponding to the first digital code, the indoor unit corresponding to the second digital code, the indoor unit corresponding to the third digital code are located in an office area, and the indoor unit corresponding to the fourth digital code and the indoor unit corresponding to the fifth digital code are located in a corridor or the like.
In the second matching, the two kinds of distribution information are cross-verified by combining the distance between the indoor units and the outer wall, so that the corresponding relation between the installation position of a part of indoor units and the digital codes can be further determined, and after the second matching, the first set of the indoor units to be matched can be simplified to obtain the second set of the indoor units to be matched. The number of indoor units to be matched in the second set is less than the number of indoor units to be matched in the first set.
In the third matching, the matching relation between the installation position of the indoor unit to be matched and the digital code in the second set is determined by combining the association degree information, so that the automatic matching of the installation position of each indoor unit in the multi-split system and the digital code is completed.
In some embodiments of the present invention, the digital code distribution information includes a first refrigerant system, a first number of indoor units, a first type of indoor units, and a digital code, and the installation location distribution information includes a second number of indoor units, a distance from the indoor units to the enclosure, a second refrigerant system, an installation location, and a second type of indoor units.
Thus, the installation position distribution information and the digital code distribution information comprise identification characteristics such as the refrigerant system, the number of indoor units, the type of the indoor units and the like of the indoor units, and a basis is provided for automatically matching the installation position and the digital code of the indoor units.
Specifically, in the digital code distribution information, the digital code of one indoor unit corresponds to a first refrigerant system, a first number of indoor units and a first type of indoor units. The generated digital code distribution information can be transmitted and stored in a form of a table.
In the installation position distribution information, the installation position of one indoor unit corresponds to the distance from one indoor unit to the enclosure structure, a second affiliated refrigerant system, a second indoor unit number and a second indoor unit type. The generated installation position distribution information can be transmitted and stored in a table form.
Referring to fig. 7, in some embodiments of the present invention, step S151 includes:
s1511: and matching the first affiliated refrigerant system, the first indoor unit number, the first indoor unit type and the second affiliated refrigerant system, the second indoor unit number and the second indoor unit type of each indoor unit of the digital coding distribution information to obtain a first matching result.
In this way, the installation positions and the digital codes of some of the plurality of indoor units can be matched.
It can be understood that the first belonging refrigerant system and the second belonging refrigerant system corresponding to the same indoor unit are the same; the number of the first internal machines corresponding to the same indoor machine is the same as the number of the second internal machines; the first internal machine type and the second internal machine type corresponding to the same indoor machine are the same.
When the refrigerant system-internal unit number-internal unit type combination corresponding to one indoor unit is different from the refrigerant system-internal unit number-internal unit type combination corresponding to any other indoor unit, that is, the number of the indoor units corresponding to one refrigerant system-internal unit number-internal unit type combination is one but not a plurality of indoor units, the corresponding relation between the installation position and the digital code of the one indoor unit can be accurately determined by matching the installation position distribution information and the digital code distribution information.
When the refrigerant system-internal unit number-internal unit type combination corresponding to one indoor unit is the same as the refrigerant system-internal unit number-internal unit type combination corresponding to at least one other indoor unit, that is, the number of the indoor units corresponding to one refrigerant system-internal unit number-internal unit type combination is multiple, the location areas of the plurality of indoor units with different digital codes can be determined through matching the installation position distribution information and the digital code distribution information, that is, the installation positions are roughly determined.
Referring to fig. 8, in some embodiments of the present invention, step S153 includes:
s1531: and matching the peripheral coefficient, the first affiliated refrigerant system, the first indoor unit number, the first indoor unit type and the distance from the indoor unit to the enclosure structure of each indoor unit of the digital coding distribution information according to the first matching result, and the second affiliated refrigerant system, the second indoor unit number and the second indoor unit type of each indoor unit of the digital coding distribution information so as to obtain a second matching result.
Thus, by adding the identification feature, the installation position and the digital code of another part of the plurality of indoor units can be matched. It can be understood that the degree to which the indoor unit approaches the building envelope is one of the conditions for identifying the installation position of the indoor unit, and on the basis that the first matching result has determined the area where the indoor unit with different digital codes is located, the installation position and the digital codes of the indoor unit approaching and far from the building envelope can be matched by further combining the peripheral coefficient, and the number of indoor units to be matched is reduced. If the final matching is not performed according to the peripheral coefficient for the second time, but is performed directly according to the association degree information, the recognition difficulty in the final matching process is increased, and the recognition accuracy is correspondingly reduced.
Specifically, the peripheral coefficient and the distance from the internal machine to the enclosure structure basically form a negative correlation, and the larger the peripheral coefficient is, the smaller the corresponding distance from the internal machine to the enclosure structure is; the smaller the peripheral coefficient, the larger the distance from the corresponding internal machine to the enclosure structure.
The indoor units with different digital codes in the digital code distribution information may be ordered according to the peripheral coefficients, for example, the indoor units with different digital codes in the digital code distribution information may be ordered according to the order of the peripheral coefficients from large to small, or the indoor units with different digital codes in the digital code distribution information may be ordered according to the order of the peripheral coefficients from small to large. Meanwhile, the indoor units with different installation positions in the installation position distribution information can be ordered according to the distance from the indoor unit to the building envelope, for example, the indoor units with different installation positions in the installation position distribution information can be ordered according to the order from the indoor unit to the building envelope, or the indoor units with different installation positions in the installation position distribution information can be ordered according to the order from the indoor unit to the building envelope.
Further, according to the first matching result, the first refrigerant system, the first internal machine type and the second refrigerant system, the second internal machine type and the second internal machine number of the indoor machine with the smallest distance from the enclosure structure in the distribution information of the first internal machine type and the first internal machine number of the indoor machine with the largest peripheral coefficient in the digital coding distribution information can be compared in sequence according to the sequence from the large peripheral coefficient to the small peripheral coefficient.
And comparing the first refrigerant system, the first internal unit type and the first internal unit number of the indoor units with the peripheral coefficient of the digital coding distribution information for a plurality of times with the second refrigerant system, the second internal unit type and the second internal unit number of the indoor units with smaller distance from the envelope structure in the installation position distribution information.
Until the first affiliated refrigerant system, the first indoor unit type and the first indoor unit number of the indoor unit with the minimum peripheral coefficient in the digital coding distribution information are compared with the second affiliated refrigerant system, the second indoor unit type and the second indoor unit number of the indoor unit with the maximum distance from the envelope structure in the installation position distribution information
And the matching relation between the installation positions of the indoor units close to and far from the enclosure structure and the digital codes is determined through comparison.
Referring to fig. 9, in some embodiments of the present invention, step S155 includes:
s1551: determining an indoor unit to be matched and a matched indoor unit according to a second matching result;
s1553: and matching the digital code distribution information with the installation position distribution information according to the association degree information corresponding to the matched indoor units so as to determine the matching relationship between the digital codes of the indoor units to be matched and the installation positions.
Thus, the installation positions and the digital codes of the rest indoor units in the plurality of indoor units can be matched according to the second matching result and the association degree information. It can be understood that in the related art, the first matching and the second matching are not performed in advance, but the installation position distribution information and the digital code distribution information are directly matched according to the association degree information, so that there are problems of large calculation amount, low recognition speed, low recognition accuracy, and the like.
Specifically, the matched indoor units are the indoor units which have already established the corresponding relation between the installation position and the digital code, and the indoor units to be matched are the indoor units which have not yet established the corresponding relation between the installation position and the digital code.
Referring to fig. 10, in some embodiments of the present invention, step S1553 includes:
S51: the searching steps are as follows: determining the number of matched indoor units in the adjacent area of each indoor unit to be matched, and taking the indoor unit to be matched with the largest number as the current indoor unit to be matched;
s53: matching: determining a matching relation between the digital codes of the current matching indoor unit and the installation position according to the association degree information of the matched indoor unit in the adjacent area of the current matching indoor unit;
s55: the circulation steps are as follows: and taking the matched current matched indoor units as matched indoor units, and repeating the searching step and the matching step until the matching relation between the digital codes and the installation positions of each indoor unit to be matched is determined.
Thus, the installation positions and the digital codes of the remaining indoor units of the plurality of indoor units can be accurately matched. It can be understood that the more the number of the matched indoor units in the adjacent area is, the more the matching installation positions of the indoor units to be matched and the identification characteristic parameters of the digital codes can be supported, the higher the accuracy of the determined matching relationship is, if one indoor unit to be matched is selected at random for matching, the matching cannot be successfully performed due to lack of the identification characteristic parameters, and therefore, in the third matching process, the indoor unit to be matched with the largest number of the matched indoor units in the adjacent area is selected each time for matching.
Specifically, the number information may be obtained by traversing the second matching result. In some embodiments of the invention, prior to the exploring step, the method further comprises: and determining the coordinates of the indoor units in the building design drawing, determining the distance between the indoor units according to the coordinates of the indoor units, and determining the adjacent areas according to the distance between the indoor units. The distance between the indoor units can be determined by calculating the distance between the coordinates of every two indoor units. Two indoor units with the inter-unit distance smaller than the preset threshold value can be determined as the indoor units in the adjacent areas.
The association degree information exists between every two indoor units, the value of the association degree information of two adjacent indoor units is usually higher, and because the association degree information is determined according to system parameters, namely the association degree information is related to the digital codes of the indoor units, the digital codes of the indoor units which are simultaneously higher in correlation with the matched indoor units can be determined by comparing the association degree information of the matched indoor units in the adjacent areas of the matched indoor units at the current installation position, and then screening is carried out according to the second matching result, the digital codes matched with the current installation position can be determined, and accordingly the corresponding relation between the installation position and the digital codes of the matched indoor units can be established.
In some embodiments, when there is no matched indoor unit in the indoor area, the indoor unit to be matched is selected as the current matched indoor unit.
Thus, the installation positions and the digital codes of the indoor units to be matched with more surrounding identification characteristic parameters are ensured to be matched preferentially. In one example, please refer to fig. 5, it is assumed that the indoor unit corresponding to the installation position a, the indoor unit corresponding to the installation position B, the indoor unit corresponding to the installation position C, and the indoor unit corresponding to the installation position D are located in an office area, and the indoor unit corresponding to the installation position E and the indoor unit corresponding to the installation position F are located in a corridor area, where the indoor unit corresponding to the installation position a, the indoor unit corresponding to the installation position B, the indoor unit corresponding to the installation position C, the indoor unit corresponding to the installation position D, and the indoor unit corresponding to the installation position E are all indoor units to be matched, the indoor unit corresponding to the installation position F is an indoor unit to be matched, and for an office area where no indoor unit to be matched exists, since the space between the indoor unit to be matched corresponding to the installation position D and the indoor unit to be matched in the corridor area is the minimum, the indoor unit to be matched corresponding to the installation position D is selected for the current indoor unit to be matched.
