[0045] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0046] The following describes, with reference to the accompanying drawings, a method for updating device mapping relationships of an air-conditioning unit, a device mapping relationship updating device of an air-conditioning unit, an air-conditioning unit, and a computer-readable storage medium according to embodiments of the present invention.

[0047] With the popularization of intelligence, existing air-conditioning units are gradually entering the stage of networked intelligent control. For the convenience of data communication and standardization of production, when the air-conditioning unit includes multiple outdoor units, each outdoor unit will be equipped with a networking module to obtain the operating data of the outdoor unit and upload the operating data of the outdoor unit to the cloud server in real time. Among them, the networking module can be a 4G (The 4th Generation Mobile Communication Technology, the fourth generation of mobile communication technology) communication module, a 5G (The 5th Generation Mobile Communication Technology, the fifth generation of mobile communication technology) communication module, or a wifi (wireless network communication technology) communication module. The networking module uploads the operating data of the air-conditioning unit to the cloud server through a mobile network or a wireless network.

[0048] The technical solution of the present application is described below by taking an air-conditioning unit including an outdoor unit as an example.

[0049] In some embodiments of the present invention, an outdoor unit, multiple indoor units connected to the outdoor unit, and a networking module corresponding to the outdoor unit, the outdoor unit and each indoor unit are communicated with each other, the outdoor unit is used to obtain the operating parameters and setting parameters of each indoor unit, and upload the operating parameters and setting parameters of the outdoor unit and the operating parameters and setting parameters of the indoor unit to the cloud server through the networking module, so that the cloud server can remotely control and monitor the air-conditioning unit in real time according to the data uploaded by the networking module.

[0050] In general, each networking module, the corresponding indoor unit, and the indoor unit connected to the outdoor unit have a corresponding mapping relationship when storing parameters. For example, the mapping relationship is: networking module-outdoor unit-number of connected indoor units-number of each indoor unit. In the cloud server, there will be a corresponding database for storing the corresponding parameter information, and a corresponding label card for displaying the parameter information. For example, each indoor unit corresponds to a database and a label card. The database is used to store the operating parameters and setting parameters of the indoor unit, and the label card is used to display the operating parameters and setting parameters. For another example, the outdoor unit also corresponds to a database and a label card. The database is used to store the operating parameters and setting parameters of the outdoor unit, and the label card is used to display the operating parameters and setting parameters of the outdoor unit.

[0051] However, when the address or device of the outdoor unit or indoor unit changes, the corresponding database and label card cannot be replaced in time, which will cause confusion in the device mapping relationship and fail to accurately display the status of the device. Figure 2As shown in the figure, (a) and (c) represent the label cards corresponding to the stopped indoor units, (b), (d) and (e) represent the label cards of the running indoor units, and (f)-(j) represent the label cards corresponding to the historical data. Due to the change of the indoor unit address, the label card of the device data mapping relationship is not deleted.

[0052] In order to solve the above problems, the present invention proposes a device mapping relationship updating method for an air-conditioning unit, which can timely update the mapping relationship, the database and the performance card corresponding to the changed identity identification when the operating parameters of the equipment change, thereby avoiding the troubles caused to users by the failure to update in time due to changes in the operating parameters.

[0053] Figure 1 The present invention is a flowchart of a method for updating a device mapping relationship of an air-conditioning unit according to an embodiment of the present invention.

[0054] like Figure 1 As shown, the device mapping relationship updating method of the air conditioning unit according to the embodiment of the present invention may include the following steps:

[0055] S1, obtaining the operating parameters of the air-conditioning unit uploaded by the networking module, wherein the operating parameters of the air-conditioning unit include the identity and operating data of the outdoor unit, the number of indoor units, and the identity and operating data of each indoor unit.

[0056] In one embodiment of the present invention, the operation data of the outdoor unit may include: the number of indoor units connected to the outdoor unit, the operating frequency of the compressor, the target frequency of the compressor, the defrosting status of the outdoor unit, the current and voltage of the outdoor unit, the outdoor ambient temperature, the condenser temperature, the exhaust temperature of the compressor, the parameters of the controller of the outdoor unit, the fault code of the outdoor unit, the outdoor wind speed status, etc., and the identity of the outdoor unit may include the SN (Serial Number, product serial number) code of the outdoor unit. The operation data of the indoor unit may include: the inlet and outlet temperatures of the indoor heat exchanger, the refrigerant flow rate, the dirty and blocked condition of the indoor heat exchanger, the power, voltage, current, etc., and the identity of the indoor unit may include the SN code and / or the indoor unit address of the indoor unit. The identity of the networking module may include the SN code (SN number) and / or the ICCID (Integrate Circuit Card Identity). It should be noted that the SN of the networking module, the indoor unit and the outdoor unit is generally a factory number, and the manufacturer will set it according to different rules to produce a role similar to the identity ID to ensure that the SN of each device is unique.

[0057] In general, the operating parameters and setting parameters of each indoor unit are transmitted to the outdoor unit through the communication line. The outdoor unit stores the parameters of each indoor unit and its own parameters, collectively referred to as global data. When a networking module is provided, the outdoor unit can establish a communication connection with the networking module according to the communication protocol. After the communication connection is established, the networking module can obtain the global data of its corresponding outdoor unit. The networking module will transmit the global data to the cloud server for remote monitoring of the air conditioning unit.

[0058] S2, according to the identity of the networking module, the identity and operation data of the outdoor unit, the number of indoor units, the identity and operation data of each indoor unit, establish a database and label card corresponding to each identity, and establish a mapping relationship between the outdoor unit, the networking module and each indoor unit.

[0059] That is to say, each device establishes a corresponding database to store the device's operating data, and establishes a corresponding label card to display the device's operating data. That is, the networking module establishes a corresponding database and label card, the outdoor unit establishes a corresponding database and label card, and each indoor unit also establishes a database and label card.

[0060] For example, when there is an outdoor unit, the connection relationship between the networking module, the outdoor unit and the indoor unit is as follows: Figure 3 As shown, the outdoor unit is used to receive the operating parameters and identity identifiers of the 1# indoor unit, the 2# indoor unit, the 3# indoor unit and the 4# indoor unit (where 1#, 2#, 3#, 4# represent the indoor unit addresses, and 101X1, 101X2, 101X3, 101X4 represent the SN of each indoor unit), and the cloud server establishes a mapping relationship based on the identity identifier, as shown in Table 1.

[0061] Table 1

[0062]

[0063] When there are multiple outdoor units, for the convenience of control, the multiple outdoor units will be divided into a master outdoor unit and multiple slave outdoor units. The master and slave outdoor units can be determined when the installer installs the air conditioning unit, and the address code of the master and slave outdoor units is saved in the corresponding outdoor unit. The outdoor unit is determined to be the master outdoor unit or the slave outdoor unit according to the address code. The master outdoor unit establishes a communication connection with the multiple slave outdoor units to receive the operating data sent by each slave outdoor unit. The master outdoor unit is also used to distribute control instructions to the corresponding slave outdoor units so that the slave outdoor units can control the indoor units connected to them.

[0064] When there are two outdoor units, the connection relationship between the master outdoor unit, the networking module corresponding to the master outdoor unit, the multiple indoor units connected to the master outdoor unit, the slave outdoor unit, the networking module corresponding to the slave outdoor unit, and the multiple indoor units connected to the slave outdoor unit is as follows: Figure 4 As shown, the cloud server establishes a mapping relationship based on the identity identifier, as shown in Table 2.

[0065] Table 2

[0066]

[0067] It should be noted that when there are multiple slave outdoor units, each slave outdoor unit is correspondingly provided with a networking module, and each slave outdoor unit is communicatively connected with the master outdoor unit, which will not be described in detail here.

[0068] S3, when the operating parameters of the networking module and / or the air-conditioning unit change, the mapping relationship, the database and the tag card corresponding to the changed identity are updated.

[0069] That is to say, when the identification of the networking module, outdoor unit, indoor unit, or the number of indoor units, or the corresponding operating data changes, the corresponding update mechanism is selected according to the content of the change to update the mapping relationship, label card, and database. For example, when the operating parameters of the indoor unit change, the database and label card of the corresponding indoor unit are updated; for another example, when the outdoor unit fails and is replaced, the SN code of the outdoor unit will change, and the database, label card, and mapping relationship of the outdoor unit are updated.

[0070] The following describes how this application updates the mapping relationship, label card and database by taking an outdoor unit, a networking module corresponding to the outdoor unit and four indoor units as an example.

[0071] According to an embodiment of the present invention, the updating method includes: when the identity of the networking module changes, updating the identity of the networking module in the mapping relationship and the database and label card corresponding to the networking module.

[0072] Specifically, taking the mapping relationship shown in Table 1 above as an example, when the networking module is replaced, its SN code will also change. At this time, only the SN code of the networking module needs to be updated, and other identity identifiers in the mapping relationship remain unchanged, and a new database and label card of the networking module are established. For example, the SN code of the networking module is updated from 00101 to 00102 (SN code of the new networking module). At this time, the SN code of the outdoor unit, the addresses of the four indoor units and the four SN codes remain unchanged, the label card and database corresponding to the outdoor unit remain unchanged, and the label cards and database corresponding to the four indoor units also remain unchanged.

[0073] According to an embodiment of the present invention, the updating method includes: when it is determined according to the operating parameters of the outdoor unit that the identity of the outdoor unit has changed, updating the identity of the outdoor unit in the mapping relationship and the database and label card corresponding to the outdoor unit.

[0074] Specifically, the mapping relationship shown in Table 1 above is still used as an example for explanation. When the SN of the networking module has not changed and the operating parameters of the indoor unit have not changed, if the outdoor unit fails and is replaced, its SN will also change. At this time, only the SN code of the outdoor unit needs to be updated, and other identity identifiers in the mapping relationship remain unchanged. A new database and label card corresponding to the outdoor unit are established. For example, the SN of the outdoor unit is updated from 101W0 to 101W1 (SN of the new outdoor unit). At this time, the SN code of the networking module, the addresses of the four indoor units, and the SN of the indoor unit remain unchanged, the database and label card corresponding to the networking module remain unchanged, and the label cards and database corresponding to the four indoor units remain unchanged.

[0075] In addition, when the operating parameters of the networking module and the outdoor unit have changed, and the operating parameters of the indoor unit have not changed, it is only necessary to update the SN of the networking module and the SN of the outdoor unit in the mapping relationship, and establish the corresponding database and label card. The four indoor unit addresses and the SN of the indoor unit remain unchanged, and the corresponding label cards and databases also remain unchanged.

[0076] The following takes the case where the operating parameters of the networking module and the outdoor unit have not changed as an example to describe in detail how to update the mapping relationship, database and label card when the operating parameters of the indoor unit change.

[0077] According to one embodiment of the present invention, the identity of each indoor unit includes the indoor unit address and / or the indoor unit SN number, wherein the updating method includes: obtaining the total number of SN numbers of all indoor units in the air-conditioning unit; when the total number of SN numbers of all indoor units is the same as the actual total number of SN numbers of all indoor units in the air-conditioning unit, updating the mapping relationship, the database and the label card corresponding to the changed identity according to the change of the indoor unit SN number.

[0078] Specifically, when the networking module can obtain the SN number of each indoor unit, the label card and the database are updated according to the SN of the indoor unit. Still taking Table 1 as an example, when there are actually 4 indoor units, if the networking module can obtain the SN numbers of 4 indoor units, it means that the SN numbers of all indoor units can be obtained. At this time, it is determined whether to update the database and the label card according to the SN number of the indoor unit. When the networking module cannot obtain the SN numbers of the 4 indoor units, the database and the label card are updated according to the indoor unit address. Among them, regardless of whether the SN numbers of all indoor units can be obtained, as long as the operating parameters of the indoor unit change, the mapping relationship needs to be updated. That is to say, when the SN number of the indoor unit can be obtained, the mapping relationship is updated according to the SN number of the indoor unit, and when the SN number of the indoor unit cannot be obtained, the mapping relationship is updated according to the address of the indoor unit.

[0079] The following describes how the networking module can obtain the SN numbers of all indoor units and how to update the mapping relationship, label card and database.

[0080] In the first case, the update is performed according to the change of the indoor unit SN number, including: when the number of indoor units is determined to remain unchanged based on the operating parameters of each indoor unit uploaded by the networking module, if the indoor unit SN number changes and the address of the indoor unit does not change, a new database and label card corresponding to the indoor unit are created, the original database corresponding to the indoor unit is sealed, and the indoor unit SN number in the mapping relationship is updated.

[0081] Specifically, when the indoor unit device is replaced and the address is the original indoor unit address, as shown in Table 3, the networking module finds that the database of the original indoor unit with SN 101X4 has no uploaded data according to the mapping relationship table, and a new indoor unit with SN code 101X5 has been added. The running data, and the label card of the 4# indoor unit has also changed. At this time, the database of the original indoor unit with SN 101X4 is sealed, and a new database and label card are established for the indoor unit with SN code 101X5, and then the SN of the indoor unit in the mapping relationship is updated. Among them, after a certain period of time (determined by the delay of the indoor unit upload, to ensure that the data of the original indoor unit can be stored in the cloud server), the label card of the original indoor unit can be automatically deleted, or the user can be reminded to delete it manually.

[0082] Table 3

[0083]

[0084] The second case is to update according to the change of the indoor unit SN number, including: when the number of indoor units is determined to remain unchanged based on the operating parameters of each indoor unit uploaded by the networking module, if the indoor unit SN number has not changed and the indoor unit address has changed, then update the indoor unit address in the mapping relationship and retain the original database and label card of the indoor unit.

[0085] Specifically, when the indoor unit address is reset, but the indoor unit is not replaced (the SN of the indoor unit has not changed), as shown in Table 4, the networking module finds that the indoor unit with SN number 101X4 still has data to upload according to the mapping relationship table, but the indoor unit address has changed. At this time, the database of the indoor unit with SN number 101X4 is processed in an inherited manner, and the operation data of the indoor unit with SN number 101X4 is displayed on the original label card, but the indoor unit address in the mapping relationship is changed from 4# to 5#. In other words, when the SN of the indoor unit has not changed and the indoor unit address has changed, there is no need to create a new label card and database, and the original database is used to store the operation data, and the original label card is used to display the operation data.

[0086] Table 4

[0087]

[0088]

[0089] The third case is to update according to the change of the SN number of the indoor unit, including: when the number of indoor units is determined to remain unchanged based on the operating parameters of each indoor unit uploaded by the networking module, if the SN number of the indoor unit changes and the address of the indoor unit also changes, a new database and label card corresponding to the indoor unit are created, the original database of the indoor unit is sealed, and the identity of the indoor unit in the mapping relationship is updated.

[0090] Specifically, when the indoor unit device is changed and the indoor unit address is reset, as shown in Table 5, the networking module finds that the indoor unit with SN number 101X4 has no data uploaded according to the mapping relationship table, and a new indoor unit with SN code 101X5 has been added. At this time, the database of the original indoor unit with SN number 101X4 is sealed, and a new database and label card are created for the indoor unit with SN number 101X5 to store the operating data of the indoor unit with SN number 101X5 and display the operating data, and then update the SN of the indoor unit in the mapping relationship. Among them, after a certain period of time (determined by the delay of the indoor unit upload, to ensure that the data of the original indoor unit can be stored in the cloud server), the label card of the original indoor unit can be automatically deleted, or the user can be reminded to delete it manually.

[0091] Table 5

[0092]

[0093] The fourth situation is to update according to the change of the indoor unit SN number, including: when it is determined that the number of indoor units connected to the outdoor unit has increased according to the operating parameters of each indoor unit uploaded by the networking module, a corresponding database and label card are created according to the identity of the newly added indoor unit, and the identity of the newly added indoor unit in the mapping relationship is updated according to the identity of the newly added indoor unit.

[0094] Specifically, when the number of indoor units changes, the number of indoor units recorded in the indoor unit will also change synchronously. Generally, the outdoor unit is reset on site by after-sales personnel. If the number of indoor units connected to the outdoor unit is not updated, an alarm will be issued. At this time, the cloud data will not add a new label card and database. When the outdoor unit is fault-free, the number of indoor units has been updated. The updated mapping relationship table is shown in Table 6. At this time, a new database and label card are established for the newly added indoor unit, which are used to store and display the operating data of the indoor unit with SN number 101X5, respectively. At the same time, the identity of the newly added indoor unit is added to the mapping relationship to update the original mapping relationship.

[0095] Table 6

[0096]

[0097] The fifth situation is to update according to the change of the indoor unit SN number, including: when it is determined that the number of indoor units connected to the outdoor unit is reduced according to the operating parameters of each indoor unit uploaded by the networking module, the corresponding label card is deleted and the corresponding database is sealed according to the reduction of the identity of the indoor unit, and the identity of the indoor unit is deleted from the mapping relationship based on the update of the identity of the indoor unit.

[0098] Specifically, when the number of indoor units changes, the number of indoor units recorded in the indoor unit will also change synchronously. Generally, the outdoor unit is reset on site by after-sales personnel. If the number of indoor units connected to the outdoor unit is not updated, an alarm will be issued. At this time, the cloud data will not reduce the label card and database. When the outdoor unit is fault-free, that is, the number of indoor units has been updated, and the updated mapping relationship table is shown in Table 7. When it is determined that the number of indoor units has decreased, the operating data of the online indoor units is further determined. When the number of indoor units that can obtain operating data is equal to the number of indoor units set by the outdoor unit, the label card of the indoor unit that has not obtained the operating parameters is deleted, and its database is sealed. At the same time, the identity of the indoor unit is reduced in the mapping relationship to update the original mapping relationship.

[0099] Table 7

[0100]

[0101] The following describes how to update the mapping relationship, label card and database when the networking module cannot obtain the N number of all indoor units.

[0102] According to one embodiment of the present invention, when the total number of SN numbers of all indoor units is different from the actual total number of SN numbers of all indoor units in the air-conditioning unit, the mapping relationship, the database and the label card corresponding to the changed identity are updated according to the indoor unit address.

[0103] Specifically, when the SN numbers of all indoor units cannot be obtained, or the number of SN numbers obtained is different from the number of indoor units set for the outdoor unit, the mapping relationship is updated according to each indoor unit address. For example, when the number of detected indoor unit addresses is the same as the number of indoor units set for the outdoor unit, the mapping relationship can be as shown in Table 8.

[0104] Table 8

[0105]

[0106] According to one embodiment of the present invention, updating is performed based on the indoor unit address, including: obtaining the number of indoor units connected to the outdoor unit, and obtaining the operating data of each indoor unit; when it is determined that the current indoor unit address is valid based on the operating data of the indoor unit, retaining the label card and database corresponding to the current indoor unit; when it is determined that the current indoor unit address is invalid based on the operating data of the indoor unit, determining the invalidity duration of the current indoor unit address; when it is determined that the sum of the number of indoor units with valid addresses and the number of indoor units with invalid addresses is less than or equal to the number of indoor units connected to the outdoor unit, keeping the label card and database of each indoor unit unchanged; when it is determined that the sum of the number of indoor units with valid addresses and the number of indoor units with invalid addresses is greater than the number of indoor units connected to the outdoor unit, deleting the label cards corresponding to the indoor units with the longest invalidity duration in turn, until the sum of the number of indoor units with valid addresses and the number of indoor units with invalid addresses is equal to the number of indoor units connected to the outdoor unit, and updating the identity of the indoor unit in the mapping relationship.

[0107] Specifically, the database changes with the change of the indoor unit address. When the indoor unit address increases or decreases, the database of the reduced indoor unit is sealed, and the database of the added indoor unit is established. When the indoor unit address returns to the original address after multiple changes, the database corresponding to the original address of the indoor unit is unsealed and continues to store operating data.

[0108] Combination Figure 5 To describe how to update the database and tag card of the indoor unit.

[0109] S501, every time period T, obtain the number of indoor units N set in the outdoor unit. Among them, one end time T is the update cycle according to the upload rate of the networking module. For example, the frequency of data upload of the networking module is once every 1 minute, and T can be correspondingly shorter, such as T is 0.5h-24h. It should be noted that when it is detected that the number of outdoor units N changes, the time T can be extended to ensure the stability of data transmission.

[0110] S502, determine whether the operation data of the indoor unit is received within a preset time. If yes, execute step S504; if not, execute step S503.

[0111] S503, record that the current indoor unit address is invalid, and record the invalid duration.

[0112] S504, record that the current indoor unit address is valid, and retain the label card and database of the current indoor unit.

[0113] S505, obtaining the number N1 of indoor units with valid addresses, and obtaining the number N2 of indoor units with invalid addresses.

[0114] S506, determine whether N1+N2≤N is established. If yes, execute step S507; if no, execute step S508.

[0115] S507, keep the label card of the original indoor unit unchanged, and keep the database of the original indoor unit unchanged.

[0116] S508: sort the invalid time lengths of the indoor units with invalid addresses in descending order of time.

[0117] S509: Remove the label cards of the indoor units with the longest invalid time in order until N1+N2=N.

[0118] It should be noted that in the above update method, as long as any one of the outdoor unit, indoor unit, and networking module changes (SN number or address), the mapping relationship needs to be updated, and there is no priority or restriction relationship between them.

[0119] In summary, the method of the present application can update the mapping relationship, label card and database in time regardless of whether the SN of the networking module changes, the SN of the outdoor unit changes, or the SN code of the indoor unit or the address of the indoor unit changes, thereby avoiding the trouble caused to users by the failure to update in time due to changes in operating parameters.

[0120] To sum up, according to the update method of the embodiment of the present invention, when the operating parameters of the device change, the mapping relationship, the database and the performance card corresponding to the changed identity identification can be updated in time, avoiding the trouble caused to users by the failure to update in time due to changes in operating parameters.

[0121] Corresponding to the above embodiment, the present invention further proposes a device for updating the equipment mapping relationship of an air-conditioning unit.

[0122] Figure 6 4 is a block diagram of a device mapping relationship updating apparatus for an air-conditioning unit according to an embodiment of the present invention.

[0123] In one embodiment of the present invention, an air conditioning unit includes an outdoor unit, a plurality of indoor units connected to the outdoor unit, and a networking module corresponding to the outdoor unit. The outdoor unit, the plurality of indoor units connected to the outdoor unit, and the networking module corresponding to the outdoor unit are connected to each indoor unit in communication, and the outdoor unit is used to obtain operating parameters and setting parameters of each indoor unit, and upload the operating parameters and setting parameters of the outdoor unit and the operating parameters and setting parameters of the indoor unit to a cloud server through the networking module, so that the cloud server can remotely control and monitor the air conditioning unit in real time according to the data uploaded by the networking module.

[0124] In general, each networking module, the corresponding indoor unit, and the indoor unit connected to the outdoor unit have a corresponding mapping relationship when storing parameters. For example, the mapping relationship is: networking module-outdoor unit-number of connected indoor units-number of each indoor unit. In the cloud server, there will be a corresponding database for storing the corresponding parameter information, and a corresponding label card for displaying the parameter information. For example, each indoor unit corresponds to a database and a label card. The database is used to store the operating parameters and setting parameters of the indoor unit, and the label card is used to display the operating parameters and setting parameters. For another example, the outdoor unit also corresponds to a database and a label card. The database is used to store the operating parameters and setting parameters of the outdoor unit, and the label card is used to display the operating parameters and setting parameters of the outdoor unit.

[0125] However, when the address or device of the outdoor unit or indoor unit changes, the corresponding database and label card cannot be replaced in time, which will cause confusion in the device mapping relationship and fail to accurately display the status of the device. Figure 2 As shown in the figure, (a) and (c) represent the label cards corresponding to the stopped indoor units, (b), (d) and (e) represent the label cards of the running indoor units, and (f)-(j) represent the label cards corresponding to the historical data. Due to the change of the indoor unit address, the label card of the device data mapping relationship is not deleted.

[0126] In order to solve the above problems, the present invention proposes an equipment mapping relationship updating device for an air-conditioning unit, which can timely update the mapping relationship, the database and the performance card corresponding to the changed identity identification when the operating parameters of the equipment change, so as to avoid the trouble caused to users by the failure to update in time due to changes in operating parameters.

[0127] like Figure 6 As shown, the device mapping relationship updating apparatus of the air-conditioning unit according to the embodiment of the present invention may include: an acquisition module 10 , a creation module 20 and an update module 30 .

[0128] Among them, the acquisition module 10 is used to obtain the operating parameters of the air-conditioning unit uploaded by the networking module, wherein the operating parameters of the air-conditioning unit include the identity and operating data of the outdoor unit, the number of indoor units, and the identity and operating data of each indoor unit. The establishment module 20 is used to establish a database and label card corresponding to each identity according to the identity of the networking module, the identity and operating data of the outdoor unit, the number of indoor units, the identity and operating data of each indoor unit, and to establish a mapping relationship between the outdoor unit, the networking module and each indoor unit. The update module 30 is used to update the mapping relationship, the database and label card corresponding to the changed identity when the operating parameters of the networking module and / or the air-conditioning unit change.

[0129] In one embodiment of the present invention, the operation data of the outdoor unit may include: the number of indoor units connected to the outdoor unit, the operating frequency of the compressor, the target frequency of the compressor, the defrosting status of the outdoor unit, the current and voltage of the outdoor unit, the outdoor ambient temperature, the condenser temperature, the exhaust temperature of the compressor, the controller parameters of the outdoor unit, the fault code of the outdoor unit, the outdoor wind speed status, etc., and the identity of the outdoor unit may include the SN (Serial Number, product serial number) code of the outdoor unit. The operation data of the indoor unit may include: the inlet and outlet temperatures of the indoor heat exchanger, the refrigerant flow rate, the dirty and blocked condition of the indoor heat exchanger, the power, voltage, current, etc., and the identity of the indoor unit may include the SN code and / or the indoor unit address of the indoor unit. The identity of the networking module may include the SN code and / or ICCID (Integrate Circuit Card Identity). It should be noted that the SN of the networking module, the indoor unit and the outdoor unit is generally a factory number, and the manufacturer will set it according to different rules to produce a role similar to the identity ID to ensure that the SN of each device is unique.

[0130] In general, the operating parameters and setting parameters of each indoor unit are transmitted to the outdoor unit through the communication line. The outdoor unit stores the parameters of each indoor unit and its own parameters, collectively referred to as global data. When a networking module is provided, the outdoor unit can establish a communication connection with the networking module according to the communication protocol. After the communication connection is established, the networking module can obtain the global data of its corresponding outdoor unit. The networking module will transmit the global data to the cloud server for remote monitoring of the air conditioning unit.

[0131] Specifically, each device establishes a corresponding database to store the device's operating data, and establishes a corresponding label card to display the device's operating data. That is, the networking module establishes a corresponding database and label card, the outdoor unit establishes a corresponding database and label card, and each indoor unit also establishes a database and label card.

[0132] For example, when there is an outdoor unit, the connection relationship between the networking module, the outdoor unit and the indoor unit is as follows: Figure 3 As shown, the outdoor unit is used to receive the operating parameters and identity identifiers of the 1# indoor unit, the 2# indoor unit, the 3# indoor unit and the 4# indoor unit (where 1#, 2#, 3#, 4# represent the indoor unit addresses, and 101X1, 101X2, 101X3, 101X4 represent the SN of each indoor unit), and the cloud server establishes a mapping relationship based on the identity identifier, as shown in Table 1 above.

[0133] When there are multiple outdoor units, in order to facilitate control, the multiple outdoor units will be divided into a master outdoor unit and multiple slave outdoor units. The method of judging the master and slave outdoor units can be determined when the installer installs the air-conditioning unit, and the address code of the master and slave outdoor units is saved in the corresponding outdoor unit. According to the address code, it is determined whether the outdoor unit is the master outdoor unit or the slave outdoor unit. A communication connection is established between the master outdoor unit and the multiple slave outdoor units to receive the operating data sent by each slave outdoor unit. The master outdoor unit is also used to distribute control instructions to the corresponding slave outdoor unit so that the slave outdoor unit can control the indoor units connected to it. When there are two outdoor units, the connection relationship between the main outdoor unit, the networking module corresponding to the main outdoor unit, the multiple indoor units connected to the main outdoor unit, the slave outdoor unit, the networking module corresponding to the slave outdoor unit, and the multiple indoor units connected to the slave outdoor unit is as follows: Figure 4 As shown, the cloud server establishes a mapping relationship based on the identity identifier, as shown in Table 2 above.

[0134] It should be noted that when there are multiple slave outdoor units, each slave outdoor unit is correspondingly provided with a networking module, and each slave outdoor unit is communicatively connected with the master outdoor unit, which will not be described in detail here.

[0135] Furthermore, when the identification of the networking module, the outdoor unit, the indoor unit, or the number of indoor units, or the corresponding operating data changes, the corresponding update mechanism is selected according to the content of the change to update the mapping relationship, the label card, and the database. For example, when the operating parameters of the indoor unit change, the database and label card of the corresponding indoor unit are updated; for another example, when the outdoor unit fails and is replaced, the SN code of the outdoor unit will change, and the database, label card, and mapping relationship of the outdoor unit are updated.

[0136] The following describes how this application updates the mapping relationship, label card and database by taking an outdoor unit, a networking module corresponding to the outdoor unit and four indoor units as an example.

[0137] Take the mapping relationship shown in Table 1 above as an example for explanation. When the networking module is replaced, its SN code will also change. At this time, you only need to update the SN code of the networking module, and the other identity identifiers in the mapping relationship remain unchanged, and establish a database and label card corresponding to the new networking module. For example, update the SN code of the networking module from 00101 to 00102 (SN code of the new networking module). At this time, the SN of the outdoor unit, the addresses of the four indoor units and the four SN codes remain unchanged, the label card and database corresponding to the outdoor unit remain unchanged, and the label cards and databases corresponding to the four indoor units remain unchanged.

[0138] When the SN of the networking module has not changed and the operating parameters of the indoor unit have not changed, if the outdoor unit fails and needs to be replaced, its SN will also change. At this time, only the SN code of the outdoor unit needs to be updated, and other identity identifiers in the mapping relationship remain unchanged. A new database and label card corresponding to the outdoor unit are established. For example, the SN of the outdoor unit is updated from 101W0 to 101W1 (SN code of the new outdoor unit). At this time, the SN code of the networking module, the 4 indoor unit addresses and the 4 SN codes remain unchanged, the database and label card corresponding to the networking module remain unchanged, and the label cards and database corresponding to the 4 indoor units also remain unchanged.

[0139] In addition, when the operating parameters of the networking module and the outdoor unit have changed, and the operating parameters of the indoor unit have not changed, it is only necessary to update the SN of the networking module and the SN of the outdoor unit in the mapping relationship, and establish the corresponding database and label card. The four indoor unit addresses and the SN of the indoor unit remain unchanged, and the corresponding label cards and databases also remain unchanged.

[0140] The following takes the case where the operating parameters of the networking module and the outdoor unit have not changed as an example to describe in detail how to update the mapping relationship, database and label card when the operating parameters of the indoor unit change.

[0141] Specifically, when the networking module can obtain the SN number of each indoor unit, the label card and the database are updated according to the SN of the indoor unit. Still taking the above Table 1 as an example, when there are actually 4 indoor units connected to the outdoor unit, if the networking module can obtain the SN numbers of 4 indoor units, it means that the SN numbers of all indoor units can be obtained. At this time, it is determined whether to update the database and the label card according to the SN number of the indoor unit. When the networking module cannot obtain the SN numbers of the 4 indoor units, the database and the label card are updated according to the indoor unit address. Among them, regardless of whether the SN numbers of all indoor units can be obtained, as long as the operating parameters of the indoor units change, the mapping relationship needs to be updated.

[0142] The following describes how the networking module can obtain the SN numbers of all indoor units and how to update the mapping relationship, label card and database.

[0143] In the first case, when the indoor unit device is replaced and the address is the original indoor unit address, as shown in Table 3 above, the networking module finds that the database of the original indoor unit with SN 101X4 has not uploaded data according to the mapping relationship table, and a new indoor unit with SN code 101X5 has been added. The operation data, and the label card of the 4# indoor unit has also changed. At this time, the database of the original indoor unit with SN 101X4 is sealed, and a new database and label card are established for the indoor unit with SN code 101X5, and then the SN of the indoor unit in the mapping relationship is updated. Among them, after a certain period of time (determined by the delay of the indoor unit upload, to ensure that the data of the original indoor unit can be stored in the cloud server), the label card of the original indoor unit can be automatically deleted, or the user can be reminded to delete it manually.

[0144] In the second case, when the indoor unit address is reset but the indoor unit is not replaced (the SN of the indoor unit has not changed), as shown in Table 4 above, the networking module finds that the indoor unit with SN number 101X4 still has data to upload based on the mapping relationship table, but the address of the indoor unit has changed. At this time, the database of the indoor unit with SN number 101X4 is processed in an inherited manner, and the operating data of the indoor unit with SN number 101X4 is displayed on the original label card, but the indoor unit address in the mapping relationship is changed from 4# to 5#. In other words, when the SN of the indoor unit has not changed and the address of the indoor unit has changed, there is no need to create a new label card and database, and the original database is used to store the operating data, and the original label card is used to display the operating data.

[0145] In the third case, when the indoor unit device is changed and the indoor unit address is reset, as shown in Table 5 above, the networking module finds that the indoor unit with SN number 101X4 has no data uploaded according to the mapping relationship table, and a new indoor unit with SN code 101X5 is added. At this time, the database of the original indoor unit with SN 101X4 is sealed, and a new database and label card are created for the indoor unit with SN number 101X5 to store the operating data of the indoor unit with SN number 101X5 and display the operating data, and then update the SN of the indoor unit in the mapping relationship. Among them, after a certain period of time (determined by the delay of the indoor unit upload, to ensure that the data of the original indoor unit can be stored in the cloud server), the label card of the original indoor unit can be automatically deleted, or the user can be reminded to delete it manually.

[0146] In the fourth case, when the number of indoor units changes, the number of indoor units recorded in the indoor unit will also change synchronously. Generally, the outdoor unit will be reset on site by after-sales personnel. If the number of indoor units connected to the outdoor unit is not updated, an alarm will be issued. At this time, the cloud data will not add a new label card and database. When the outdoor unit is fault-free, the number of indoor units has been updated. The updated mapping relationship table is shown in Table 6 above. At this time, a new database and label card are established for the newly added indoor unit, which are used to store and display the operating data of the indoor unit with SN number 101X5, respectively. At the same time, the identity of the newly added indoor unit is added to the mapping relationship to update the original mapping relationship.

[0147] In the fifth case, when the number of indoor units changes, the number of indoor units recorded in the indoor unit will also change synchronously. Generally, the outdoor unit will be reset on site by after-sales personnel. If the number of indoor units connected to the outdoor unit is not updated, an alarm will be issued. At this time, the cloud data will not reduce the label card and database. When the outdoor unit is fault-free, that is, the number of indoor units has been updated, and the updated mapping relationship table is shown in Table 7 above. When it is determined that the number of indoor units has decreased, the operating data of the online indoor units is further determined. When the number of indoor units that can obtain operating data is equal to the number of indoor units set by the outdoor unit, the label card of the indoor unit that has not obtained the operating parameters is deleted, and its database is sealed. At the same time, the identity of the indoor unit is reduced in the mapping relationship to update the original mapping relationship.

[0148] The following describes how to update the mapping relationship, label card and database when the networking module cannot obtain the N number of all indoor units.

[0149] Specifically, when the SN numbers of all indoor units cannot be obtained, or the number of SN numbers obtained is different from the number of indoor units set for the outdoor unit, the mapping relationship is updated according to each indoor unit address. For example, when the number of detected indoor unit addresses is the same as the number of indoor units set for the outdoor unit, the mapping relationship can be as shown in Table 8.

[0150] The database changes with the change of the indoor unit address. When the indoor unit address increases or decreases, the database of the reduced indoor unit is sealed and the database of the added indoor unit is established. When the indoor unit address returns to the original address after multiple changes, the database corresponding to the original address of the indoor unit is unsealed and continues to store operating data.

[0151] At intervals of T, the number of indoor units N set by the outdoor unit is obtained. Among them, one end time T is the update cycle according to the upload rate of the networking module. For example, the frequency of data upload of the networking module is once every 1 minute, and T can be correspondingly shorter, such as T is 0.5h-24h. It should be noted that when the number of outdoor units N is detected to have changed, the time T can be extended to ensure the stability of data transmission. When the current indoor unit address is invalid, the invalid duration is recorded; when the current indoor unit address is valid, the label card and database of the current indoor unit are retained. The number of indoor units with valid addresses N1 is obtained, and the number of indoor units with invalid addresses N2 is obtained. When N1+N2≤N, the label card and database of the original indoor unit are kept unchanged; when N1+N2>N, the invalid duration of the indoor units with invalid addresses is sorted in order from long to short, and the label cards of the indoor units with the longest invalid duration are removed in order until N1+N2=N.

[0152] In summary, no matter the SN of the networking module changes, the SN of the outdoor unit changes, or the SN code or address of the indoor unit changes, the mapping relationship, label card and database can be updated in time to avoid the trouble caused to users by the failure to update in time due to changes in operating parameters.

[0153] It should be noted that, for the details disclosed in the device mapping relationship updating apparatus of the air-conditioning unit in the embodiment of the present invention, please refer to the details disclosed in the device mapping relationship updating method of the air-conditioning unit in the embodiment of the present invention, and the details will not be repeated here.

[0154] According to the updating device of the embodiment of the present invention, when the operating parameters of the device change, the mapping relationship, the database and the performance card corresponding to the changed identity identification can be updated in time, thereby avoiding the trouble caused to users by the failure to update in time due to the change of operating parameters.

[0155] Corresponding to the above embodiment, the present invention also proposes an air conditioning unit.

[0156] Figure 7 Schematic diagram of a block diagram of an air conditioning unit according to an embodiment of the present invention.

[0157] like Figure 7 As shown, the air-conditioning unit 700 of the embodiment of the present invention includes a memory 710, a processor 720, and a device mapping relationship update program of the air-conditioning unit stored in the memory 710 and can be executed on the processor 720. The processor 720 executes the device mapping relationship update method of the air-conditioning unit on the device mapping relationship update of the air-conditioning unit.
