Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0037] The present application will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present application can be combined with each other.

[0038] The following is combined Figure 1 This application describes a multi-split air conditioning system according to some embodiments.

[0039] This application provides a multi-split air conditioning system, such as Figure 1 As shown, it includes: a first control panel 1, at least one second control panel 2, and an indoor unit 3; the indoor unit 3 is connected to the first control panel 1 and at least one second control panel 2 via a power line communication line.

[0040] In this embodiment, the indoor unit can be either a central air conditioning unit or a split-type air conditioning unit. The specific form of the air conditioner is not limited in this embodiment. Specifically, the indoor unit of a central air conditioning system differs from that of a split-type air conditioner because they typically serve multiple rooms or the entire building. A central air conditioning system provides cooling or heating services to multiple indoor units through a centralized refrigerant handling unit (outdoor unit).

[0041] In some examples, the air conditioning control panel is the main interface for interaction between the user and the air conditioning system. It allows users to set and adjust various operating parameters, such as temperature, fan speed, and mode (cooling, heating, dehumidification, etc.). For a central air conditioning system, the control panel can be a standalone device or integrated into each indoor unit. In the embodiments of this application, the control panel is a standalone device, and the first control panel and the second control panel can be the main control panel and the secondary control panel, respectively.

[0042] In this embodiment, Power Line Communication (PLC) is a technology that utilizes existing power lines for data transmission. It allows the transmission of electrical energy and digital information along the same power line, reducing the need for additional wiring and maintaining reliable communication over long distances. PLC technology is widely used in smart homes, smart grids, industrial automation, and other fields.

[0043] In this embodiment, a first control panel, at least one second control panel, and an indoor unit are connected via a power line communication (PLC) line. Electrical energy and signals can be transmitted via the PLC line, and these signals may include analog signals, digital signals, electrical signals, etc. For example, when it is necessary to control the air conditioner's automated functions, the signal corresponding to the automated function can be transmitted to the indoor unit via the PLC line, and the indoor unit adjusts based on the received signal. Similarly, when the air conditioner needs to be upgraded, the corresponding upgrade control command can be transmitted to the indoor unit via the PLC line, and the indoor unit performs the corresponding upgrade process.

[0044] Compared with existing technologies, the multi-split air conditioning system of this embodiment includes a first control panel, at least one second control panel, and an indoor unit. The indoor unit is connected to the first control panel and at least one second control panel via a power line communication line. Power and signals can be transmitted simultaneously via the power line communication line. When it is necessary to upgrade the air conditioner or control the automatic operation function of the air conditioner, the operation can be performed on the first or second control panel, and the signal is transmitted to the indoor unit via the power line communication line. This enables the air conditioner to be controlled through the first and second control panels, eliminating the need to use mobile smart devices to control the air conditioner and improving the user experience.

[0045] Optionally, the first control screen 1 corresponds to a first control plugin on the smart device side, and the second control screen 2 corresponds to a second control plugin on the smart device side, with the first control plugin having more functions than the second control plugin.

[0046] Optionally, the functional difference between the first control plugin and the second control plugin is at least as follows: the first control plugin has the function of automatic configuration of cloud scenarios.

[0047] In some examples, the control permissions of the first control screen and the second controller are different, and the control permissions of the first control screen are higher than those of the second control screen. For example, the first control screen can directly control other devices, such as humidifiers, smart lights, curtains and other home appliances, through cloud control. However, if the second control screen needs to control other devices through cloud control, it must send cloud control commands through the first control screen as an agent. For example, the second control screen sends the cloud control commands to the first control screen, and then the first control screen sends the cloud control commands to the server to control other devices.

[0048] In this embodiment of the application, the server can be a cloud server or a central server. Specifically, the central server can be a server set up locally.

[0049] In some examples, the functions corresponding to the first control plug-in may include air conditioning control, smart home device control, and automation setting functions; the functions corresponding to the second control plug-in may include air conditioning control and smart home device control.

[0050] Specifically, the air conditioning control function can be the function of controlling the indoor unit and / or outdoor unit of the air conditioner; the smart home device control function can be the function of controlling the smart home; and the automation setting function can be the function of setting and running automation on the smart terminal, such as setting the air conditioner and humidifier to turn on simultaneously according to a certain trigger condition (such as when the indoor temperature reaches a certain temperature).

[0051] In this embodiment, the first control screen 1 can be the main control screen in a multi-split air conditioning system, and the second control screen 2 can be the secondary control screen in the multi-split air conditioning system. It should be noted that the internal structure of the first control screen 1 and the second control screen 2 is the same. However, when the automation function is controlled and operated through a smart terminal, it can only be operated based on the operation interface of the first control screen in the smart terminal. That is, the operation interface of the second control screen in the smart terminal cannot be used to operate and control the automation function. For example, the automation function can be to set the indoor unit or home equipment to run at a fixed time, or to set the indoor unit or home equipment to run automatically according to a predetermined mode, and so on. No further examples will be given here.

[0052] For example, if a user needs to control the indoor unit in room 1 to operate the automation function via a mobile phone, the user can only control the indoor unit to operate the automation function through the operation interface of the first control screen on the mobile phone, and cannot control the indoor unit to operate the automation function through the operation interface of the second control screen on the mobile phone.

[0053] It should be noted that the difference between the first control panel 1 and the second control panel 2 is that the server stores the corresponding control relationship between the first control panel 1 and the controlled device, but does not store the corresponding control relationship between the second control panel 2 and the controlled device. Therefore, when the user inputs a command to the second control panel 2, the second control panel 2 needs to act as an agent through the first control panel 1 to upload the control command to the server. The server needs to rely on the control association information between the first control panel 1 and the controlled device to control the home appliances.

[0054] Optionally, both the first control screen 1 and the second control screen 2 are defined with control attributes, and the control attributes of the first control screen 1 and the second control screen 2 can be switched between each other.

[0055] It should be noted that control attributes can be main screen control attributes and secondary screen control attributes. For example, if the first control screen is the main screen, then the second control screen is the secondary screen; conversely, if the first control screen is the secondary screen, then the second control screen is the main screen.

[0056] Optionally, the first control panel 1 and / or the second control panel 2 may include at least two of the following modules: a Bluetooth module, a Wi-Fi module, and a high-voltage interface module.

[0057] In some examples, a High Voltage Interface Module (HVIM) refers to a component in an electrical system used to handle and manage high voltage or high current.

[0058] For example, the first control panel 1 and / or the second control panel 2 can connect to smart home devices or indoor units via Bluetooth modules. The first control panel 1 and / or the second control panel 2 can also connect to a local area network via Wi-Fi modules. The first control panel 1 and / or the second control panel 2 can also connect to smart home devices via power interface modules. For example, the first control panel 1 and / or the second control panel 2 can connect to smart lights via power interface modules.

[0059] Optionally, the multi-split air conditioning system includes a bus, one end of which is connected to the first control panel 1 and the second control panel 2 respectively, and the other end is connected to the bus interface of the indoor unit.

[0060] It should be noted that the first control panel 1 and the second control panel 2 can be connected to the indoor unit via a bus and communicate with the indoor unit. As an optional method, the first control panel 1 and the second control panel 2 can also be directly connected via a bus for communication, which is not limited here.

[0061] Optionally, the multi-split air conditioning system in this application embodiment also includes an outdoor unit 4; the outdoor unit 4 is connected to the indoor unit 3 via a power line communication line.

[0062] In this embodiment, the outdoor unit is an important component of a split or central air conditioning system. It is primarily responsible for transferring indoor heat to the outdoor environment while providing power to the entire air conditioning system.

[0063] In some examples, the outdoor unit can be a central outdoor unit or a split outdoor unit. The specific type of outdoor unit is not limited in the embodiments of this application. However, it should be noted that the outdoor unit needs to be used in conjunction with the indoor unit. That is, the central indoor unit needs to correspond to the central outdoor unit, and the split indoor unit needs to correspond to the split outdoor unit.

[0064] In this embodiment, the outdoor unit is connected to the indoor unit via a power line communication line, which is a technology that uses power lines for data transmission. This method can simplify the installation process and reduce the need for additional wiring. It can also transmit power and signals between the indoor and outdoor units simultaneously.

[0065] In a specific example, when it is necessary to control the automatic function of the air conditioner, the signal corresponding to the automatic function can be transmitted to the indoor unit through the power line communication line. The indoor unit then transmits the signal to the outdoor unit through the power line communication line, and the indoor and outdoor units adjust together based on the received signals.

[0066] For example, when an air conditioner needs to be upgraded, the corresponding upgrade control command can be transmitted to the indoor unit via a power line communication line, and the indoor unit can then transmit the control command to the outdoor unit via the power line communication line, so that the indoor and outdoor units can be upgraded accordingly.

[0067] Optionally, the indoor unit includes a control module 31; the control module 31 is connected to the first control panel 1, at least one second control panel 2, and the outdoor unit 4 via a power line communication line.

[0068] In this embodiment, the control module can be connected to the first control panel, the second control panel, and the outdoor unit. For example, when it is necessary to control the automatic function of the air conditioner, the signal corresponding to the automatic function can be transmitted to the control module in the indoor unit through the power line communication line, and the control module can then transmit the signal to the outdoor unit through the power line communication line.

[0069] Optionally, if the air conditioner needs to be upgraded, the corresponding upgrade control command can be transmitted to the control module in the indoor unit via a power line communication line, and the control module can then transmit the control command to the outdoor unit via the power line communication line.

[0070] For example, if the power line communication is PowerBus, the control module can be a PowerBus master station, and the first control panel, at least one second control panel, and the outdoor unit can be PowerBus slave stations. Specifically, PowerBus is a technology that uses power lines for data communication, and it is particularly suitable for scenarios that require the simultaneous transmission of electrical energy and control signals. In air conditioning systems, PowerBus can be used to enable communication between the outdoor and indoor units, simplifying wiring and improving system integration.

[0071] In some examples, when a user sets parameters such as temperature and mode through the first control panel, the master station in the indoor unit can convert these settings into signals and inject them into the power line through a coupler. The signals are then transmitted to at least one second control panel and the outdoor unit through the power line. After receiving the instructions from the master station, the outdoor unit adjusts its operating status (such as compressor speed and fan speed) and sends the status information back to the indoor unit for the user to view or for further automation control. Correspondingly, after receiving the instructions from the master station, the second control panel can adjust its own displayed parameter status to be the same as the parameters displayed on the first control panel.

[0072] Similarly, when a user sets parameters such as temperature and mode through any of the second control panels, the master station in the indoor unit can convert these settings into signals and inject them into the power line through a coupler. The signals are then transmitted to the first control panel, other second control panels, and the outdoor unit through the power line. After receiving the instructions from the master station, the outdoor unit adjusts its operating status (such as compressor speed and fan speed) and sends the status information back to the indoor unit for the user to view or for further automation control. Correspondingly, after receiving the instructions from the master station, the first control panel and other second control panels can adjust their own display parameter status to be the same as the control panel display parameters adjusted by the user.

[0073] Optionally, the first control screen 1 includes a first touch screen 11 and a first control button group 12; the first touch screen 11 and the control button group 12 are respectively connected to the control module 21 through power line communication lines.

[0074] Optionally, the first control button group 12 includes three control buttons; the first control button group 12 is located on one side of the first touch screen.

[0075] It should be noted that the control button group in this application can be a physical button or a smart button. The specific form of the control button is not limited in the embodiments of this application.

[0076] In this embodiment of the application, the first control button group may include a first control button, a second control button, and a third control button. Each button in the first control button group has a different control function. It should be noted that the first control button group may also include other numbers of control buttons. The specific number of buttons in the first control button group is not limited here.

[0077] For example, the first control button can be used to control the air conditioner temperature and fan speed, the second control button can be used to control the air conditioner cooling or heating mode, the third control button can be used to control the air conditioner timer, and so on.

[0078] Optionally, the second control screen 2 includes a second touch screen 21 and a second control button group 22; the second touch screen 21 and the second control button group 22 are respectively connected to the control module through power line communication lines.

[0079] Optionally, the second control button group 22 includes three control buttons; the second control button group is located on one side of the second touch screen 2.

[0080] It should be noted that at least one second control button group 22 in this application may include at least one fourth control button, at least one fifth control button and at least one sixth control button. The buttons in at least one second control button group 22 may be physical buttons or smart buttons. The specific form of the control buttons is not limited in the embodiments of this application.

[0081] In this embodiment, the control functions of at least one fourth control button, at least one fifth control button, and at least one sixth control button are different.

[0082] For example, at least one fourth control button can be used to control the air conditioner temperature and fan speed, at least one fifth control button can be used to control the air conditioner cooling or heating mode, at least one sixth control button can be used to control the air conditioner timer, and so on.

[0083] In this embodiment, the first control button has the same control function as at least one fourth control button, the second control button has the same control function as at least one fifth control button, and the third control button has the same control function as at least one sixth control button.

[0084] For example, if the control function corresponding to the first control button is to control the air conditioner temperature and fan speed, then at least one fourth control button corresponds to the control function of controlling the air conditioner temperature and fan speed; if the control function corresponding to the second control button is to control the air conditioner cooling or heating mode, then at least one fifth control button corresponds to the control function of controlling the air conditioner cooling or heating mode; if the control function corresponding to the third control button is to control the air conditioner timer, then at least one sixth control button corresponds to the control function of controlling the air conditioner timer, and so on.

[0085] Optionally, the power line communication line in this embodiment is a PowerBus line.

[0086] Specifically, PowerBus is a technology that utilizes existing power lines for data communication, allowing the transmission of electrical energy and digital information on the same wire. This technology is particularly suitable for scenarios that require simplified wiring and improved system integration, such as smart homes, smart grids, and building automation systems.

[0087] It should be noted that connecting via PowerBus lines allows for the connection of various smart devices (such as lights, sockets, sensors, thermostats, etc.) to achieve centralized control and remote management. It can also monitor the power consumption of home appliances and help users optimize their energy usage habits.

[0088] For example, such as Figure 2 As shown in the device interaction diagram of this application embodiment, the actual scenario includes: outdoor unit 4, indoor unit 3, first control panel 1, and second control panel 2. The smart control panel 2 communicates with the indoor unit 3 via Powerbus. Each control panel has three physical buttons, and each button can be connected to a physical light or converted into a wireless switch to set up automated scene control devices. The control panel buttons can be configured to have synchronized or asynchronous states. When configured synchronously, controlling the button on the main control panel 1 also executes the corresponding button on the secondary control panel 2; for example, pressing the left button 11 on the main control panel 1 changes the state of the left button on the secondary control panel 2, pressing the middle button on the main control panel 1 changes the state of the middle button on the secondary control panel 2, and pressing the right button on the main control panel 1 changes the state of the right button on the secondary control panel 2. Similarly, controlling the button on the secondary control panel 1 also executes the corresponding button on the main control panel 1. When configured asynchronously, the buttons on the main control panel 1 and the secondary control panel 2 execute independently without affecting each other.

[0089] Compared with existing technologies, the multi-split air conditioning system of this embodiment includes a first control panel, at least one second control panel, and an indoor unit. The indoor unit is connected to the first control panel and at least one second control panel via a power line communication line. Power and signals can be transmitted simultaneously via the power line communication line. When it is necessary to upgrade the air conditioner or control the automatic operation function of the air conditioner, the operation can be performed on the first or second control panel, and the signal is transmitted to the indoor unit via the power line communication line. This enables the air conditioner to be controlled through the first and second control panels, eliminating the need to use mobile smart devices to control the air conditioner and improving the user experience.

[0090] Based on the above-mentioned multi-split air conditioning system, this application embodiment also provides a smart home system, which includes the above-mentioned multi-split air conditioning system and at least one smart home device, which is connected to at least one of the first control panel and the second control panel via a power line communication line.

[0091] Optionally, the aforementioned physical devices may also include a user interface, a network interface, a camera, radio frequency (RF) circuitry, sensors, audio circuitry, a Wi-Fi module, etc. The user interface may include a display screen, input units such as a keyboard, etc., and optional user interfaces may also include USB interfaces, card reader interfaces, etc. The network interface may optionally include standard wired interfaces, wireless interfaces (such as Wi-Fi interfaces), etc.

[0092] Those skilled in the art will understand that the physical device structure provided in this embodiment does not constitute a limitation on the physical device, and may include more or fewer components, or combine certain components, or have different component arrangements.

[0093] Through the above description of the embodiments, those skilled in the art can clearly understand that this application can be implemented using software plus necessary general-purpose hardware platforms, or it can be implemented through hardware. By applying the solution of this embodiment, compared with the existing technology, the multi-split air conditioning system of this embodiment includes a first control panel, at least one second control panel, and an indoor unit; the indoor unit is connected to the first control panel and at least one second control panel via a power line communication line. Power and signals can be transmitted simultaneously via the power line communication line. When it is necessary to upgrade the air conditioner or control the automatic operation function of the air conditioner, operation can be performed on the first or second control panel, and the signal is then transmitted to the indoor unit via the power line communication line, thereby realizing the control of the air conditioner through the first and second control panels. This eliminates the need for mobile smart devices to control the air conditioner, improving the user experience.
