[0002] In traditional multi-split air conditioning units, each outdoor unit and indoor unit need to communicate. During installation, the more indoor and outdoor units there are and the farther apart they are, the more and longer the communication lines need to be connected. The increased number of lines exacerbates the possibility of incorrect wiring, making the installation more complex. Moreover, at present, the communication between indoor and outdoor units is basically high-voltage communication, which poses certain risks. The complexity of the wiring places relatively high demands on installation and use. Summary of the Invention

[0019] If the response time of the sub-unit meets the preset response time, and it is determined that each sub-unit has fed back the search response information, then the search result is generated based on the search response information.

[0020] If the response time of the sub-unit does not meet the preset response time and / or at least one sub-unit fails to provide the search response information, then the sub-unit that fails to provide the search response information is marked and removed from the Bluetooth network.

[0028] Based on the network information of the main outdoor unit, if the sub-outdoor unit and the sub-indoor unit are multi-connected units, and the number of online sub-indoor units matches the number of online sub-outdoor units, then the search result is generated;

[0029] Based on the networking information of the main outdoor unit, if the sub-outdoor unit and the sub-indoor unit are multi-unit systems, and it is determined that the number of online sub-indoor units does not match the number of sub-indoor units included in the search network command, then an alarm message is generated.

[0030] Specifically, this embodiment provides an implementation method for generating machine search results based on the number of online sub-indoor units and the number of online sub-outdoor units.

[0031] According to one embodiment of the present invention, the step of generating the search result based on the number of online indoor units and the number of online outdoor units specifically includes:

[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] The present invention will now be described in detail with reference to the accompanying drawings. The specific operation methods in the method embodiments can also be applied to the device embodiments or system embodiments. In the description of the present invention, unless otherwise stated, "at least one" includes one or more. "Multiple" refers to two or more. For example, at least one of A, B, and C includes: A existing alone, B existing alone, A and B existing simultaneously, A and C existing simultaneously, B and C existing simultaneously, and A, B, and C existing simultaneously. In the present invention, " / " means "or". For example, A / B can mean A or B. "And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone.

[0056] The present invention will now be described in detail with reference to specific embodiments.

[0057] In some specific embodiments of the present invention, such as Figures 1 to 3 As shown, this solution provides a networking method for air conditioners, applied to the main indoor unit. The method includes:

[0058] Based on the search and networking command, the indoor unit that receives the search and networking command is assigned as the main indoor unit, and the remaining indoor units are assigned as sub-indoor units. The search and networking command includes at least the networking information of the main outdoor unit, the number of sub-outdoor units, and the number of sub-indoor units connected to the sub-outdoor units.

[0059] Based on the device search and networking command, a device search prompt command is generated and broadcast within the Bluetooth network range. The device search prompt command includes a prompt message to the sub-unit indicating that it has entered the networking state.

[0060] Based on the fact that the device search prompt command meets the preset prompt conditions, the device search and play command is broadcast within the Bluetooth network range. The device search result is generated and sent to the host unit based on the device search response information fed back by the sub-unit. The device search and play command includes the sub-unit address information that identifies the sub-unit, and the device search response information is the feedback information from the sub-unit based on the device search and play command.

[0061] It should be noted that existing air conditioner indoor units are connected via communication lines, which is cumbersome and difficult to install. This invention uses Bluetooth to enable communication between indoor units, reducing installation difficulty, avoiding complex wiring, and improving the efficiency of networking between the outdoor and indoor units of the air conditioner.

[0062] Furthermore, in traditional multi-split air conditioning units, one outdoor unit is designated as the main outdoor unit, and the indoor unit connected to the main outdoor unit is designated as the main indoor unit. In this invention, the indoor units connected to the main outdoor unit are designated as the main indoor units, and the remaining indoor units are designated as sub-indoor units. The system then transmits the relevant commands for searching for the units via Bluetooth network to confirm the search for the indoor units and feed back the search results to the main outdoor unit, thereby realizing a multi-split network of outdoor and indoor units.

[0063] In a possible embodiment, the search and networking command includes the networking information of the main outdoor unit. The networking information of the main outdoor unit includes the main outdoor unit's address information, the number of sub-outdoor units connected to the main outdoor unit and their address information, as well as the distribution of the main outdoor unit and sub-outdoor units. For example, the main outdoor unit and sub-outdoor units may be located in the same area, or they may be located in different areas. The information about the area settings is provided because the location of the main outdoor unit and sub-outdoor units within the area will affect the communication method between the indoor and outdoor units, i.e., multi-connection communication or non-multi-connection communication.

[0064] In a possible embodiment, the device search and networking command is a device search command sent by the main outdoor unit after it connects to the indoor unit. After receiving the device search and networking command, the indoor unit connected to the main outdoor unit sets itself as the main indoor unit, sets the other indoor units in the Bluetooth network as sub-indoor units, and sends subsequent device search commands.

[0065] In a possible embodiment, the device search prompt command is a prompt command issued by the master internal unit to the sub-internal unit, which is used to prompt the sub-internal unit to prepare to enter the network connection. Upon receiving the device search prompt command, the sub-internal unit enters the waiting device search state from other states.

[0066] In one application scenario, monitoring and after-sales equipment can connect to the network of indoor and outdoor units via Bluetooth, avoiding the previous problem of needing to access the communication bus to view air conditioner parameters, and reducing the difficulty of later equipment maintenance and on-site problem handling.

[0067] In some possible embodiments of the present invention, the step of satisfying preset prompt conditions based on the sending of the search prompt command specifically includes:

[0068] Get the real-time status of all sub-machines;

[0069] When all internal units are in the off state, the sending of the machine search prompt command meets the preset prompt conditions.

[0070] If at least one sub-unit is in a non-power-off state and the number of times the search prompt command is sent reaches the preset number of times, then the sub-unit in the non-power-off state will be marked and removed from the Bluetooth network.

[0071] Specifically, this embodiment provides an implementation method based on sending a search prompt command that meets preset prompt conditions. During the networking process, the internal unit may be in various states, such as power-on state, running state, test state, etc. The internal unit determines that it has been assigned as a sub-internal unit according to the received search prompt command. At the same time, regardless of the state of the sub-internal unit at this time, it is adjusted to the power-off state so that the main internal unit and the sub-internal unit can search for and play on the device.

[0072] It should be noted that after receiving the search prompt, the sub-unit may not switch to or remain in the off state due to network failure or its own device issues. In this case, the main unit will send the search prompt again and obtain the status of the sub-unit. If the sub-unit still does not switch to the off state after a preset number of sends, it is determined that the sub-unit cannot form a network. The sub-unit will be removed from the Bluetooth network and marked to facilitate the rapid identification of the faulty sub-unit for maintenance or troubleshooting.

[0073] In one application scenario, the main indoor unit broadcasts a search prompt command at least three times via Bluetooth network. If any sub-indoor unit is still not powered off after the three search prompt commands are broadcast, then the sub-indoor unit is removed from the Bluetooth network.

[0074] In some possible embodiments of the present invention, the step of broadcasting a device search and play command within the Bluetooth network range specifically includes:

[0075] Based on the machine search and networking instructions, determine the number of sub-units and the sub-unit address information of each sub-unit;

[0076] Based on the number of sub-units and their address information, broadcast the machine search and play command one by one.

[0077] Specifically, this embodiment provides an implementation method for broadcasting search and play commands within a Bluetooth network range. After the main unit determines the number of sub-units and their corresponding address information based on the search and network configuration command, it broadcasts the search and play commands one by one within the Bluetooth network range.

[0078] This can be understood as follows: when there are multiple sub-units, the main unit assigns numbers to the sub-units based on their number and address information, and then performs a request for the corresponding number within the Bluetooth network range. Upon receiving the relevant information, the sub-units provide feedback and response, thereby determining the corresponding search results to facilitate subsequent network setup.

[0079] In one application scenario, the search and networking command identifies five sub-internal units connected to the sub-external unit. The host obtains the sub-internal unit address information and assigns them sequential numbers, such as sub-internal unit 1, sub-internal unit 2, ..., sub-internal unit 5, etc. After numbering, the host internal unit broadcasts the search and request command for the corresponding sub-internal unit. In other words, within the Bluetooth network, the host internal unit broadcasts a call to sub-internal unit 1. After receiving the call, sub-internal unit 1 responds or provides no feedback. The host internal unit generates the search results based on the relevant responses.

[0080] Furthermore, a waiting time is set for the response of sub-unit 1. After the waiting time is reached, it indicates that sub-unit 1 has no response. At this time, the main unit broadcasts a call to sub-unit 2.

[0081] In a possible implementation, after receiving a broadcast call from the main internal unit, the sub-unit will respond within 5ms. If the main internal unit does not receive a response from the corresponding sub-unit within 50ms, it will determine that the sub-unit is in a state of no response, malfunction, or offline.

[0082] In a possible implementation, after receiving a broadcast call from the main internal unit, the sub-unit responds within 5ms. If the main internal unit does not receive feedback from the corresponding sub-unit within 50ms, it broadcasts a call to the corresponding sub-unit again. After a certain number of consecutive calls, such as 3 times, it is determined that the sub-unit is in a state of no feedback, malfunction, or offline.

[0083] In some possible embodiments of the present invention, the step of generating a search result to be sent to the main external unit based on the search response information fed back by the internal unit specifically includes:

[0084] Based on the address information of each sub-unit, obtain the machine search response information of each sub-unit;

[0085] If the response time of the sub-unit meets the preset response time, and it is determined that each sub-unit has fed back the search response information, then the search result is generated based on the search response information.

[0086] If the response time of the sub-unit does not meet the preset response time and / or at least one sub-unit fails to provide a response to the search for the device, the sub-unit that fails to provide a response to the search for the device will be marked and removed from the Bluetooth network.

[0087] Specifically, this embodiment provides an implementation method for generating search results sent to the main external unit. After receiving the response information from the corresponding sub-internal unit, the main internal unit counts the number of sub-internal units that have responded, determines that the number of sub-internal units that have responded with search results corresponds to the number of sub-internal units identified by the search network command, and then generates search results based on the search results from all sub-internal units.

[0088] Furthermore, if the number of sub-units responding to the search for devices does not correspond to the number of sub-units identified by the search for devices networking command, the sub-units that did not respond to the search for devices will be marked and removed from the Bluetooth network, so that the faulty sub-units can be quickly identified for maintenance or troubleshooting.

[0089] In some possible embodiments of the present invention, the step of generating a search result to be sent to the main external unit based on the search response information fed back by the internal unit specifically includes:

[0090] Based on the number of machine search response messages and the address information of the sub-internal unit, determine the number of online sub-internal units.

[0091] The number of online sub-external units is determined based on the search response information, wherein the search response information sent by the sub-internal unit includes information on whether there are any online sub-external units connected.

[0092] The search results are generated based on the number of online internal and external sub-units.

[0093] Specifically, this embodiment provides another implementation method for generating and sending the search results to the main outdoor unit. After the sub-indoor unit responds with the corresponding search response information, it determines the connection between the sub-indoor unit and the sub-outdoor unit, and counts the corresponding sub-indoor unit address information and sub-outdoor unit address information to determine the connection between the sub-indoor unit and the sub-outdoor unit, and generates the search results. Then, it sends the search results to the sub-outdoor unit to determine the final networking of the air conditioner's indoor and outdoor units.

[0094] Furthermore, the indoor and outdoor units may be connected in a one-to-one correspondence, or there may be cases where they are not connected. Therefore, it is necessary to determine the connection status of the indoor and outdoor units, whether they are connected in a one-to-one correspondence, and whether they are connected to the nearest unit. If there is a difference from the expected connection status, adjustments are made. If the expected connection requirements are met, the networking is considered complete.

[0095] It should be noted that the data transmission and processing center is still based on the main outdoor unit, but each outdoor unit can freely choose its installation location and only needs to communicate with the nearest indoor unit, which can solve the problem of limited installation area.

[0096] In some possible embodiments of the present invention, the step of generating the machine search result based on the number of online indoor units and the number of online outdoor units specifically includes:

[0097] Based on the network information of the main outdoor unit, if the sub-outdoor and sub-indoor units are multi-connected, the number of online sub-indoor units and the number of online sub-outdoor units are matched, and then the machine search results are generated.

[0098] Based on the network information of the main outdoor unit, if the number of online sub-outdoor units and sub-indoor units is determined to be mismatched with the number of sub-indoor units included in the search network command, an alarm message will be generated.

[0099] Specifically, this embodiment provides an implementation method for generating machine search results based on the number of online indoor units and the number of online outdoor units. The indoor and outdoor units may be connected in a one-to-one correspondence, or there may be cases where they are not connected. Therefore, the connection status of the indoor and outdoor units is determined, whether it is a one-to-one correspondence, and whether it is connected to the nearest unit. If there is a difference from the expected connection status, adjustments are made. If the expected connection requirements are met, the network is considered complete.

[0100] It should be noted that multi-connection networking is mainly divided into two cases: one is multiple outdoor units connected, and the other is no multiple outdoor units connected. Depending on the connection method of the outdoor units, the acquisition of the search response information of the sub-indoor units and the generation of the corresponding search results are determined. This embodiment is based on multiple outdoor units connected.

[0101] Furthermore, based on the number of online sub-units and the number of online sub-external units, if it is determined that the number of online sub-units and the number of online sub-external units match the information identified in the network information of the main external unit, then the machine search result is generated.

[0102] Furthermore, if the number of online indoor units and the number of online outdoor units do not match the information identified in the network information of the main outdoor unit, it indicates a fault and requires troubleshooting. Based on relevant problem information, such as the mismatch in numbers, alarm information is generated to facilitate subsequent maintenance and troubleshooting.

[0103] In an application scenario, such as Figure 2 As shown, when the outdoor unit is multi-unit, the main outdoor unit and the sub-outdoor units are located in at least two installation areas. This installation method can meet the needs of users with smaller installation areas. At this time, the outdoor unit can communicate with any adjacent indoor unit. After the main outdoor unit informs the main indoor unit that the outdoor unit is multi-unit, the main indoor unit determines the connection status of the sub-indoor unit and the sub-outdoor unit based on this information.

[0104] In some possible embodiments of the present invention, the step of generating the machine search result based on the number of online indoor units and the number of online outdoor units specifically includes:

[0105] Based on the network information of the main outdoor unit, if the sub-outdoor and sub-indoor units are not multi-connected units, the number of online sub-indoor units and the number of online sub-outdoor units are matched, and then the machine search results are generated.

[0106] Based on the network information of the main outdoor unit, if the number of online sub-indoor units and sub-indoor units is not a multi-connector, and the number of online sub-indoor units does not match the number of sub-outdoor units included in the search network command, an alarm message will be generated.

[0107] Specifically, this embodiment provides another implementation method for generating machine search results based on the number of online sub-indoor units and the number of online sub-outdoor units. The indoor and outdoor units may be connected in a one-to-one correspondence, or there may be cases where they are not connected. Therefore, it is necessary to determine the connection status of the indoor and outdoor units, whether they are connected in a one-to-one correspondence, and whether they are connected to the nearest unit. If there is a difference from the expected connection status, adjustments are made. If the expected connection requirements are met, the network is considered complete.

[0108] It should be noted that multi-connection networking is mainly divided into two cases: one is multiple external units connected, and the other is no multiple external units connected. Depending on the connection method of the external units, the acquisition of the search response information of the sub-internal units and the generation of the corresponding search results are determined. This embodiment is based on the case where no multiple external units are connected.

[0109] Furthermore, based on the number of online sub-units and the number of online sub-external units, if it is determined that the number of online sub-units and the number of online sub-external units match the information identified in the network information of the main external unit, then the machine search result is generated.

[0110] Furthermore, if the number of online indoor units and the number of online outdoor units do not match the information identified in the network information of the main outdoor unit, it indicates a fault and requires troubleshooting. Based on relevant problem information, such as the mismatch in numbers, alarm information is generated to facilitate subsequent maintenance and troubleshooting.

[0111] In an application scenario, such as Figure 3 As shown, when the outdoor unit is not multi-unit, the main outdoor unit and the sub-outdoor unit are located in the same installation area. This installation method is suitable for situations with a large installation area. In this case, the sub-outdoor unit communicates with the indoor unit through the main outdoor unit, and the main outdoor unit transmits various data through its connection with the main indoor unit.

[0112] It should be noted that when the outdoor unit is not multi-unit, the outdoor unit may need to connect with the indoor unit to enable communication between the two. In this case, it is also necessary to obtain the address information of the sub-indoor unit and the sub-outdoor unit to ensure that the connected outdoor and indoor units meet the preset networking requirements.

[0113] Furthermore, when the outdoor unit is not multi-unit, the purpose of connecting the outdoor unit and the indoor unit is to determine the optimal distance. That is, by checking whether the connection status of the outdoor unit and the indoor unit matches the address information of the sub-indoor unit and the sub-outdoor unit obtained by the main indoor unit, and whether the proximity principle is met, it is determined whether the connection status needs to be adjusted.

[0114] In a possible implementation, if the main indoor unit informs the main indoor unit that the outdoor unit is not in a multi-connection state, the main indoor unit begins to query the connection status of each indoor and outdoor unit. For example, the main indoor unit queries sub-indoor unit 2 to see if there is a connected sub-outdoor unit, and if so, what the sub-outdoor unit's address information is. If sub-outdoor unit 2 has a sub-outdoor unit, it replies that it exists and provides the sub-outdoor unit's address information; if it does not exist, it replies that it does not exist. This process continues until all sub-indoor units have completed their on-demand playback.

[0115] In some specific embodiments of the present invention, such as Figures 1 to 4 As shown, this solution provides a networking device for an air conditioner, applied to the main indoor unit. The device includes:

[0116] The instruction receiving module 100 is used to assign the indoor unit that receives the search and networking instruction to the main indoor unit and the remaining indoor units to the sub-indoor units based on the search and networking instruction. The search and networking instruction includes at least the networking information of the main outdoor unit, the number of sub-outdoor units, and the number of sub-indoor units connected to the sub-outdoor units.

[0117] The instruction broadcasting module 200 is used to generate a search prompt instruction based on the search and networking instruction, and broadcast the search prompt instruction within the Bluetooth network range. The search prompt instruction includes a prompt message to the sub-unit indicating that it has entered the networking state.

[0118] The result generation module 300 is used to broadcast a search and play command within the Bluetooth network range based on the preset prompt conditions of the search and play prompt command, and generate a search result to be sent to the host unit based on the search and play response information fed back by the sub-unit.
