[0036] The following describes embodiments of the present invention in detail, 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 are not to be construed as limiting the present invention.

[0037] The following describes a multi-connected system and its external unit positioning method, device, electronic device, and storage medium according to an embodiment of the present invention with reference to the accompanying drawings.

[0038] Figure 1 is a schematic structural diagram of a multi-connected system according to an embodiment of the present invention. Figure 2 FIG is a schematic diagram of the structure of a multi-connected system according to another embodiment of the present invention. Figure 1 and Figure 2 As shown, there can be one or more multi-split systems, each of which includes at least one external unit (e.g., 1-4 units) and at least one internal unit 200 (e.g., 1-64 units). Each external unit (110, 120, and 130) is provided with an audio device (111, 121, and 131). The audio device (111, 121, and 131) can be a buzzer, which can be provided in a controller (not shown) of the external unit.

[0039] by Figure 1Taking a multi-split system shown as an example, the multi-split system includes two external units (110 and 120) and multiple internal units 200. One of the two external units (110 and 120) is a master external unit 110, and the other is a slave external unit 120. The master external unit 110 and the slave external unit 120 are connected via a communication line, and the multiple internal units 200 are connected to the master external unit 110 via a communication line.

[0040] by Figure 2 As shown in the figure, the two multi-split systems are respectively a first multi-split system and a second multi-split system. The first multi-split system includes one outdoor unit and multiple indoor units 200. Therefore, the outdoor unit is the main outdoor unit 130, and the multiple indoor units 200 are connected to the main outdoor unit 130 through communication lines; the second multi-split system includes two outdoor units (110 and 120) and multiple indoor units 200. The structure of the second multi-split system is the same as that of the first multi-split system. Figure 1 The structure of the multi-connected system shown is the same.

[0041] Further, such as Figure 1 and Figure 2 As shown, each outdoor unit (110, 120, and 130) is also provided with a networking module (112, 122, and 132). The networking module (112, 122, and 132) can upload the real-time operating information of the corresponding multi-split system to the cloud server 300, and can send control commands from the cloud server 300 to the corresponding outdoor unit and the corresponding indoor unit. The real-time operating information of the multi-split system includes operating data, control parameters, engineering setting parameters, etc., wherein the operating data includes but is not limited to the sensor detection data of the outdoor unit and the indoor unit itself (such as ambient temperature, high pressure in the air conditioning system, etc.), data calculated by the main control chip (such as exhaust superheat, real-time capacity of the indoor unit, etc.), data from the external components of the multi-split system and transmitted through the bus of the multi-split system through the networking module (such as outdoor unit power, indoor humidity sensor data, etc.), and operating status parameters (such as indoor / outdoor unit operating mode, outdoor unit mute setting, indoor unit address, set temperature, etc.).

[0042] Therefore, the external unit positioning method of the multi-split system of this embodiment can be applied to the cloud server 300. The networking modules (112, 122 and 132) upload the operation information of the corresponding multi-split system to the cloud server 300. The cloud server 300 generates control instructions for the audio devices (111, 121 and 131) and sends the control instructions to the corresponding networking modules. The corresponding networking modules receive the control instructions, and the controller of the corresponding external unit controls the audio device.

[0043] It should be noted that in actual applications, the number of outdoor units in a multi-split system is not limited to one or two. Figure 1 and Figure 2 The structure of the multi-connected system shown is merely exemplary and is not intended to limit the present application.

[0044] Figure 3 FIG. 1 is a flow chart of a method for locating an external unit of a multi-connected system according to an embodiment of the present invention. Figure 3 As shown in the figure, the external unit positioning method of the multi-split system includes:

[0045] S301, when all multi-split systems are in the power-on state, determine the target multi-split system according to the system to be located, and obtain the mute state of each outdoor unit in the target multi-split system.

[0046] Specifically, the cloud server can only control the audio device of each external unit in the multi-connected system when the multi-connected system is powered on and meets the mute state, or when the multi-connected system is in the shutdown state. Therefore, it is necessary to first determine whether all multi-connected systems are powered on and obtain the mute state of each external unit in the target multi-connected system. The system to be located may be a faulty multi-connected system that needs repair, and the target multi-connected system is a multi-connected system in the same working area as the system to be located. The operating sound of each external unit in the target multi-connected system will interfere with the sound of the audio device of each external unit in the system to be located. Therefore, it is necessary to obtain the mute state of each external unit in the target multi-connected system.

[0047] In an optional embodiment, before determining whether all multi-split systems are in the power-on state, the cloud server also needs to index the cloud platform database and query the serial number of the gateway directly connected to the main outdoor unit in the multi-split system. If the gateway directly connected to the main outdoor unit in the multi-split system is online, the outdoor unit can be quickly found through the outdoor unit positioning method of the present application. If the gateway directly connected to the main outdoor unit in the multi-split system is not online, the outdoor unit cannot be quickly found through the outdoor unit positioning method of the present application.

[0048] S302, when the mute status of each external unit in the target multi-connected system meets the preset mute conditions, control the audio devices of all external units in the system to be located to send a first prompt message, so as to locate all external units in the system to be located according to the first prompt message.

[0049] Specifically, when the mute state of each external unit in the target multi-connected system meets the preset mute conditions, it indicates that the external units in the same working area as the system to be located are all in a mute state and will not interfere with the sound of the audio device. Therefore, a first prompt message can be sent by controlling the audio devices of all external units in the system to be located, and the user can locate all external units of the system to be located according to the first prompt message.

[0050] In the above embodiment, when the outdoor unit is in silent state, the first prompt message is sent by controlling the audio device in the outdoor unit, so that maintenance personnel can locate the outdoor unit through the first prompt message, shortening the maintenance time and thus improving the maintenance efficiency.

[0051] In some embodiments, the silent state includes a silent mode state and a silent gear state, and the method further includes: when the silent mode state of each external unit in the target multi-split system is respectively in the on state, and the silent gear state of each external unit in the target multi-split system is greater than or equal to the preset silent gear, determining that the silent state of each external unit in the target multi-split system meets the preset silent conditions.

[0052] Specifically, the cloud server can obtain the silent mode status and silent gear status. If the silent mode is off, the corresponding outdoor unit is in non-silent mode; if the silent mode is on, the corresponding outdoor unit is in silent mode. In addition, when the outdoor unit is in silent mode, the silent gear status of the outdoor unit also needs to be obtained. Different silent gears correspond to different maximum wind speeds and maximum compressor frequencies of the outdoor unit. The higher the silent gear, the quieter the outdoor unit sound. When the silent gear status of each outdoor unit in the target multi-connected system is greater than or equal to the preset silent gear, the operating sound of each outdoor unit in the target multi-connected system will not interfere with the audio device, and the outdoor unit can be searched.

[0053] For example, if the preset silent mode is 5, the corresponding maximum outdoor unit speed is 680 rpm and the maximum frequency is 60 Hz. Silent modes 1-4 correspond to higher maximum speeds and higher compressor frequencies than Silent 5. Silent modes 6 and above correspond to lower maximum speeds and lower compressor frequencies than Silent 5.

[0054] In the above embodiment, whether the outdoor unit is in silent mode and whether the silent gear state of the outdoor unit meets the preset silent gear is determined to determine whether the current silent gear meets the requirement for searching for the outdoor unit.

[0055] In some embodiments, when the mute status of at least one external unit in the target multi-split system does not meet the preset mute condition, the method also includes: controlling the external unit in the target multi-split system whose mute mode is off to turn on the mute mode, and adjusting the mute gear status of each external unit in the target multi-split system to the preset mute gear.

[0056] It is understandable that when the silent state of the outdoor unit does not meet the preset silent condition, it may be that the outdoor unit is not in silent mode, or it may be that the silent gear state of the outdoor unit does not meet the preset silent gear state. Therefore, it is necessary to control the outdoor unit whose silent mode state is off to turn on the silent mode, and set the external gear state of all outdoor units in the target multi-split system to the preset silent gear state, so that the silent state of each outdoor unit in the target multi-split system meets the preset silent condition.

[0057] It should be noted that when adjusting the mute status of a multi-connected system, it will affect the operation of the multi-connected system. Therefore, when there are multiple multi-connected systems, if the mute status of the target multi-connected system needs to be adjusted, the user's permission must be obtained.

[0058] In some embodiments, after all external units of the system to be located are located according to the first prompt message, the method further includes: controlling the audio devices of all external units in the system to be located to stop sending the first prompt message; and restoring the mute state of each external unit in the target multi-connected system to the mute state before adjustment.

[0059] Specifically, after the user locates all external units of the system to be located according to the first prompt message, the audio device is no longer required to send the first prompt message. Therefore, the audio devices controlling all external units in the system to be located stop working. Moreover, after the mute state is adjusted before, it will affect the operating state of the multi-connected system, so the mute state of each external unit in the target multi-connected system also needs to be restored to the mute state before the adjustment.

[0060] In the above embodiment, if the mute state of the external unit is adjusted before the audio device is controlled to send the first prompt message, it will affect the operating state of the multi-connected system. Therefore, after all external units in the positioning system are positioned, the mute state of the external unit needs to be restored to the mute state before the adjustment, so that the multi-connected system can restore its previous operating state, which has less impact on the user's comfort.

[0061] In some embodiments, controlling the audio devices of all external units of the system to be located to send a first prompt message includes: controlling the audio devices of all external units of the system to be located to send the first prompt message within a first preset time and at a first preset time interval.

[0062] That is, the cloud server sends control instructions to the audio devices of all external devices in the system to be located through the gateways of the corresponding external devices at a first preset time interval, causing the audio devices of all external devices in the system to be located to emit a first prompt message and continue to do so for a first preset time. For example, if the audio device is a buzzer, the buzzer is controlled to operate for a seconds, then stop for b seconds, and continue to sound for c minutes.

[0063] It should be noted that, when there are multiple external units in the system to be located, it is necessary to control the audio devices of all external units to send out the first prompt message at the same time.

[0064] In some embodiments, the method further includes: obtaining an identity identifier of the system to be located; and determining the number of the multi-connected systems according to the identity identifier of the system to be located.

[0065] Specifically, the identity identifier can be the serial number of the indoor unit or the serial number of the outdoor unit of the system to be located. When a multi-split system encounters a malfunction, poor cooling / heating effect, abnormal noise, or other passive after-sales work order, the user can follow the customer service's instructions to find the serial number of the indoor unit in the affected area to report the problem and record it. After the user authorizes the activation of active after-sales service, the manufacturer generates an after-sales work order, and the cloud server can obtain the serial number of the outdoor unit or indoor unit. The cloud server obtains the number of multi-split systems in the project based on the serial number of the indoor unit or outdoor unit reported for repair, and then checks whether all systems are in the power-on state.

[0066] In some embodiments, when there is only one multi-connected system, determining a target multi-connected system based on the system to be located includes: determining the system to be located as the target multi-connected system.

[0067] It is understandable that if there is only one multi-connected system, the multi-connected system is the system to be located, and the system to be located is the target multi-connected system.

[0068] In some embodiments, the method further includes: when the system to be located is in a shutdown state, controlling the audio devices of all external units in the system to be located to send a first prompt message within a second preset time period and at a second preset time interval.

[0069] Specifically, if there is only one multi-connected system, and the system to be located fails, it may be in a shutdown state and will not interfere with the sound of the audio device. Therefore, the cloud server can send control instructions to the audio devices of the corresponding external devices through the gateways of all external devices in the system to be located multiple times within a second preset time period and at a second preset time interval. For example, the cloud server can send control instructions to the audio devices of the corresponding external devices three times within d minutes, so that the audio devices of all external devices in the system to be located emit the first prompt message. In this case, the audio devices of all external devices in the system to be located can also emit the first prompt message within the first preset time period and at the first preset time interval.

[0070] In some embodiments, after controlling the audio devices of all external units in the system to be located to send a first prompt message according to a second preset time interval, the method further includes: if the audio devices of all external units in the system to be located do not send the first prompt message, sending a second prompt message, wherein the second prompt message is used to indicate that the audio devices of all external units in the system to be located have failed to execute.

[0071] That is, after the cloud server sends control instructions to the audio devices of the corresponding external units multiple times within the second preset time, if the audio devices of all external units in the system to be located do not send the first prompt message, the cloud server determines that the audio devices of all external units in the system to be located have failed to execute, and therefore, sends a second prompt message to remind the user that the audio devices of all external units in the system to be located have failed to execute.

[0072] In an optional embodiment, the cloud server may also control the audio devices of all external units in the system to be located to send a first prompt message within a second preset time. If the audio devices of all external units in the system to be located do not send the first prompt message, the cloud server may control the audio devices of all external units in the system to be located to send the first prompt message again until the second preset time is reached.

[0073] In some embodiments, when there are multiple multi-split systems, determining a target multi-split system based on the system to be located includes: determining the system to be located and a multi-split system in the same working area as the system to be located as the target multi-split system.

[0074] Specifically, when there are multiple multi-connected systems, the operating sound of the multi-connected systems in the same working area as the system to be located will interfere with the sound of the audio device of the system to be located, so it is necessary to identify the system to be located and the multi-connected systems in the same working area as the system to be located as the target multi-connected systems.

[0075] In an optional implementation, if the working area of the multi-connected system has been divided in the engineering project, when determining whether the multi-connected system is in the power-on state, it is also possible to only determine whether the target multi-connected system is in the power-on state, rather than determining whether all multi-connected systems are in the power-on state.

[0076] The technical solution of this application is further described in detail below in conjunction with specific implementation methods:

[0077] like Figure 4 As shown, in the case where there is only one multi-split system, the method for locating the external unit of the multi-split system includes the following steps:

[0078] S401, querying the serial number of the gateway directly connected to the main outdoor unit in the multi-connection system;

[0079] S402, determining whether the gateway directly connected to the main outdoor unit in the multi-connected system is online, if yes, executing step S403, if not, executing step S412.

[0080] S403, determining whether the multi-connection system is in an on state, if yes, executing step S404, if not, executing step S407.

[0081] S404, determining whether the mute state of each external unit in the multi-split system meets the preset mute condition, if yes, executing step S406, if not, executing step S405.

[0082] S405, controlling the outdoor units in the multi-split system whose silent mode is off to turn on the silent mode, and adjusting the silent gear state of each outdoor unit in the multi-split system to a preset silent gear, and then executing step S406.

[0083] S406: Within a first preset time, the audio devices of all external units of the multi-connected system are controlled to send a first prompt message according to a first preset time interval.

[0084] S407: Within the second preset time, control the audio devices of all external units in the multi-connected system to send out a first prompt message according to the second preset time interval, and then execute step S408.

[0085] S408, determining whether the audio devices of all external units in the multi-connected system send out a first prompt message, if yes, executing step S409, if not, executing step S411.

[0086] S409: Control the audio devices of all external units in the multi-connected system to stop sending the first prompt message.

[0087] S410, restoring the mute state of each outdoor unit in the multi-split system to the mute state before adjustment.

[0088] S411: Send a second prompt message, wherein the second prompt message is used to indicate that the audio device execution of all external units in the multi-connected system has failed.

[0089] S412: Determine that the multi-connected system cannot execute the external unit positioning method.

[0090] In summary, according to the method for locating an external unit of a multi-split system according to an embodiment of the present invention, when all multi-split systems are in the powered-on state, the target multi-split system is determined based on the system to be located, and the mute state of each external unit in the target multi-split system is obtained. When the mute state of each external unit in the target multi-split system satisfies the preset mute conditions, the audio devices of all external units in the system to be located are controlled to send a first prompt message, so as to locate all external units in the system to be located according to the first prompt message. Thus, when the external unit is in the mute state, by controlling the audio device in the external unit to send the first prompt message, maintenance personnel can locate the external unit through the first prompt message, thereby shortening maintenance time and improving maintenance efficiency.
