The second correspondence between the third identification code, the second identification code and the first identification code refers to a one-to-one correspondence between the third identification code, the second identification code and the first identification code, and taking the example that the first identification code is a product serial number SN, the second identification code is an international mobile equipment identification code IMEI, and the third identification code is a System, the second correspondence can be expressed as a System: (SN + IMEI).
In one embodiment, the backend server may be configured to update the second correspondence between the third identity code, the second identity code, and the first identity code by performing the following operations:
judging whether a second corresponding relation to which the first identification code received currently belongs exists in a second corresponding relation stored currently by the background server or not according to the first identification code received currently by the background server; and if the second corresponding relationship currently stored does not have the second corresponding relationship to which the first identification code currently received by the background server belongs, establishing and storing the corresponding second corresponding relationship according to the first identification code currently received by the background server, the second identification code in the relevant state parameter and the third identification code of the multi-split air-conditioning subsystem to which the Internet of things communication equipment belongs, which corresponds to the relevant state parameter.
An example is as follows: the second corresponding relationship currently stored by the background server includes System1: (SN 1+ IMEI 1) and System1: (SN 2+ IMEI 1), the state parameters corresponding to the indoor unit 3 sent by the internet of things communication equipment 1 currently received by the background server include a second identification code IMEI1 of the internet of things communication equipment 1 and a first identification code SN3 of the indoor unit 3, wherein the multi-split air-conditioning subsystem to which the internet of things communication equipment 1 belongs is the multi-split air-conditioning subsystem 1, and the third identification code of the multi-split air-conditioning subsystem 1 is System1. After determining that there is no second corresponding relationship to which the first identification code SN3 belongs in the second corresponding relationship currently stored by the background server, indicating that the indoor unit 3 is a newly added indoor unit in the multi-split air conditioning subsystem 1, the second corresponding relationship established and stored for the indoor unit 3 according to the first identification code SN3, the second identification code IMEI1 and the third identification code System1 is System1: (SN 3+ IMEI 1), namely when a new indoor/outdoor unit is added to the system, manual configuration is not needed, the background server can automatically store the newly added indoor/outdoor unit identification code, the internet of things communication equipment accessed by the newly added indoor/outdoor unit and the affiliated multi-split air conditioner subsystem.

An example is as follows: the first identification codes currently received by the background server comprise first identification codes SN1 and SN2 of indoor units 1-2 in the multi-split air conditioner subsystem 1, and the second corresponding relation currently stored by the background server comprises System1: (SN 1+ IMEI 1), system1: (SN 2+ IMEI 1) and System1: (SN 3+ IMEI 1), and the first identifiers in the three second correspondences are SN1, SN2, and SN3, respectively. Through judgment, it can be determined that the first identification code currently received by the background server does not contain System1: a first identification code SN3 corresponding to (SN 3+ IMEI 1).
Step 2: if the currently received first identification code does not contain the first identification code corresponding to a certain second corresponding relation, judging whether the first identification code corresponding to the certain second corresponding relation is in an offline state or not; if the state is in the loss of contact counting time state and the continuous loss of contact time reaches a preset time threshold value, deleting the certain second corresponding relation; and if the first identification code corresponding to the certain second corresponding relation is not in the loss-of-contact-counting state, performing loss-of-contact-counting processing on the first identification code corresponding to the certain second corresponding relation (marking the first identification code corresponding to the certain second corresponding relation as in the loss-of-contact-counting state and starting timing).
The following describes step 2 in detail by taking data sent by the internet of things communication device in three consecutive data reporting periods (e.g., 1 hour) as an example. The state parameters of the indoor unit and the outdoor unit are not changed in the three continuous data reporting periods, and the preset time threshold is 2 hours.
1 st data reporting period: the first identification code received by the background server does not contain System1: and (SN 3+ IMEI 1) corresponding to the first identifier SN3 (for brevity, the first identifier SN3 corresponding to the System1 (SN 3+ IMEI 1) is simply referred to as a target identifier) and the target identifier is not in the loss-of-contact counting state, performing loss-of-contact counting processing on the target identifier.
The 2 nd data reporting period: the first identification code received by the background server does not contain the target identification code, and the continuous loss time of the target identification code is 1 hour.
The 3 rd data reporting period: the first identification code received by the background server does not contain the target identification code, and the continuous loss time of the target identification code is 2 hours. Further, since the continuous loss of connection time reaches the preset time threshold (2 hours), which indicates that the indoor unit 3 corresponding to the target identification code has been removed from the multi-split air conditioning System, the second correspondence System1 stored in the background server is deleted: (SN 3+ IMEI 1).
The internet of things communication device in the multi-split air conditioning system in the embodiment of the invention collects the state parameters of each indoor/outdoor unit in communication connection with the main control outdoor unit through the main control outdoor unit, and sends the state parameters (including but not limited to a first identification code of the indoor/outdoor unit, a HomeBus communication address and a second identification code of the internet of things communication device) corresponding to a certain indoor/outdoor unit to the background server after detecting that the state parameters of the certain indoor/outdoor unit are changed. Therefore, even if the identification code of the indoor unit and/or the outdoor unit is changed due to abnormal operation of a software program and the like, the background server can quickly and accurately acquire the changed identification code, so that the stable operation of the multi-split air conditioning system is ensured. Further, the internet of things communication device may also periodically send the state parameters (including but not limited to the first identification code of the indoor/outdoor unit, the HomeBus communication address, and the second identification code of the internet of things communication device) corresponding to each indoor/outdoor unit to the background server according to a preset data reporting period. Therefore, even if the indoor/outdoor units are added, deleted and replaced in the multi-split air-conditioning system, the background server can accurately acquire the identification codes of the indoor/outdoor units in the multi-split air-conditioning system, the identification codes of the indoor/outdoor units do not need to be manually configured and maintained by technicians, and the operation reliability and stability of the multi-split air-conditioning system are further improved.
So far, the technical solution of the present invention has been described with reference to one embodiment shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
