Maintenance engineers typically need to locate the outdoor unit via refrigerant piping or communication lines between the indoor and outdoor units, increasing repair time and reducing overall efficiency. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the first objective of this invention is to propose a method for locating the outdoor unit of a multi-split air conditioning system. When the outdoor unit is in a silent state, a first prompt message is emitted by controlling the audio device inside the outdoor unit, allowing maintenance personnel to locate the outdoor unit based on the first prompt message, thus shortening maintenance time and improving maintenance efficiency.

[0008] To achieve the above objectives, according to a first aspect of the present invention, a method for locating the outdoor units of a multi-split air conditioning system is proposed. The multi-split system has at least one outdoor unit, and each outdoor unit is equipped with an audio device. The method includes: with all multi-split systems powered on, determining a target multi-split system based on the system to be located, and obtaining the mute status of each outdoor unit in the target multi-split system; and, when the mute status of each outdoor unit in the target multi-split system satisfies preset mute conditions, controlling the audio devices of all outdoor units in the system to be located to issue a first prompt message, so as to locate all outdoor units of the system to be located according to the first prompt message.

[0009] According to the outdoor unit positioning method of the multi-split air conditioning system of the present invention, when all multi-split air conditioning systems are powered on, a target multi-split air conditioning system is determined based on the system to be positioned, and the silent state of each outdoor unit in the target multi-split air conditioning system is obtained. If the silent state of each outdoor unit in the target multi-split air conditioning system meets preset silent conditions, the audio devices of all outdoor units in the system to be positioned are controlled to issue a first prompt message, so as to locate all outdoor units in the system to be positioned based on the first prompt message. Therefore, when the outdoor unit is in a silent state, by controlling the audio device inside the outdoor unit to issue a first prompt message, maintenance personnel can locate the outdoor unit based on the first prompt message, shortening maintenance time and improving maintenance efficiency.

[0016] According to an embodiment of the present invention, the method further includes: when the system to be located is in a shutdown state, controlling the audio devices of all outdoor units in the system to be located to issue a first prompt message according to a second preset time interval within a second preset time period.

[0017] According to one embodiment of the present invention, after controlling the audio devices of all outdoor units in the system to be located to issue a first prompt message according to a second preset time interval, the method further includes: issuing a second prompt message if the audio devices of all outdoor units in the system to be located do not issue the first prompt message, wherein the second prompt message is used to indicate that the audio devices of all outdoor units in the system to be located have failed to execute.

[0018] According to one embodiment of the present invention, when there are multiple multi-split air conditioning systems, determining the target multi-split air conditioning system based on the system to be located includes: determining the system to be located and the multi-split air conditioning system located in the same working area as the system to be located as the target multi-split air conditioning system.

[0019] To achieve the above objectives, a computer-readable storage medium is provided according to a second aspect of the present invention, on which a computer program is stored, which, when processed by a processor, executes the outdoor unit positioning method of any of the preceding embodiments of the multi-unit system.

[0020] According to an embodiment of the present invention, a computer-readable storage medium, by executing a computer program of the above-described multi-unit system outdoor unit positioning method, when the outdoor unit is in a silent state, controls the audio device inside the outdoor unit to issue a first prompt message, enabling maintenance personnel to locate the outdoor unit through the first prompt message, thereby shortening maintenance time and improving maintenance efficiency.

[0021] To achieve the above objectives, an electronic device is provided according to a third aspect of the present invention, including a memory, a processor, and a multi-unit system outdoor unit positioning program stored in the memory and executable on the processor. When the processor executes the multi-unit system outdoor unit positioning program, it implements the multi-unit system outdoor unit positioning method of any of the foregoing embodiments.

[0024] According to an embodiment of the present invention, the outdoor unit positioning device for a multi-split air conditioning system determines the target multi-split air conditioning system based on the system to be positioned when all multi-split air conditioning systems are powered on using a first determining module. It then acquires the silent state of each outdoor unit in the target multi-split air conditioning system using a first acquiring module. Finally, when the silent state of each outdoor unit in the target multi-split air conditioning system meets preset silent conditions using a first control module, it controls the audio devices of all outdoor units in the system to be positioned to emit a first prompt message, thereby locating all outdoor units in the system to be positioned based on the first prompt message. Thus, by controlling the audio devices within the outdoor units to emit the first prompt message while the outdoor units are in a silent state, maintenance personnel can locate the outdoor units using the first prompt message, shortening maintenance time and improving maintenance efficiency.

[0036] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] The following description, with reference to the accompanying drawings, describes a multi-unit air conditioning system and its outdoor unit positioning method, apparatus, electronic equipment, and storage medium according to embodiments of the present invention.

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

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

[0040] by Figure 2 Taking the two multi-split air conditioning systems shown as examples, the two systems are the first multi-split system and the 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 via 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 similar to... Figure 1 The multi-split air conditioning systems shown have the same structure.

[0041] Furthermore, such as Figure 1 and Figure 2 As shown, each outdoor unit (110, 120, and 130) is also equipped with a network module (112, 122, and 132). These network modules (112, 122, and 132) can upload real-time operating information of the corresponding multi-split system to the cloud server 300, and can also send control commands from the cloud server 300 to the corresponding outdoor and indoor units. The real-time operating information of the multi-split system includes operating data, control parameters, and engineering setting parameters. Operating data includes, but is not limited to, data detected by sensors on the outdoor and indoor units themselves (such as ambient temperature and high pressure within the air conditioning system), data calculated by the main control chip (such as exhaust superheat and the real-time capabilities of the indoor unit), data transmitted via the network module from external components of the multi-split system through the system's bus (such as outdoor unit power and indoor humidity sensor data), and operating status parameters (such as indoor / outdoor unit operating mode, outdoor unit silent setting, indoor unit address, and set temperature).

[0042] Therefore, the outdoor unit positioning method of the multi-unit system in this embodiment can be applied to the cloud server 300. The network modules (112, 122 and 132) upload the corresponding multi-unit system operation information to the cloud server 300. The cloud server 300 generates control commands for the audio devices (111, 121 and 131) and sends the control commands to the corresponding network modules. The corresponding network modules receive the control commands, and the controllers of the corresponding outdoor units control the audio devices.

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

[0044] Figure 3 This is a flowchart illustrating a method for locating the outdoor unit of a multi-split air conditioning system according to an embodiment of the present invention. Figure 3 As shown, the outdoor unit positioning method for a multi-split air conditioning system includes:

[0045] S301, with all multi-split systems powered on, determines the target multi-split system based on the system to be located, and obtains the silent status of each outdoor unit in the target multi-split system.

[0046] Specifically, the cloud server can only control the audio devices of each outdoor unit in a multi-split system when the system is powered on and in a silent state, or when the system is powered off. Therefore, it is necessary to first determine whether all multi-split systems are powered on and obtain the silent state of each outdoor unit in the target multi-split system. The system to be located can be a faulty multi-split system requiring repair, and the target multi-split system is the multi-split system located in the same working area as the system to be located. The operating noise of each outdoor unit in the target multi-split system will interfere with the audio devices of each outdoor unit in the system to be located; therefore, it is necessary to obtain the silent state of each outdoor unit in the target multi-split system.

[0047] In one optional implementation, before determining whether all multi-unit systems are powered on, the cloud server also needs to index the cloud platform database and query the gateway serial number directly connected to the main outdoor unit in the multi-unit system. If the gateway directly connected to the main outdoor unit in the multi-unit system is online, the outdoor unit can be quickly located using the outdoor unit location method of this application. If the gateway directly connected to the main outdoor unit in the multi-unit system is offline, the outdoor unit cannot be quickly located using the outdoor unit location method of this application.

[0048] S302, when the silent state of each outdoor unit in the target multi-split system meets the preset silent conditions, control the audio devices of all outdoor units in the system to be located to issue a first prompt message, so as to locate all outdoor units in the system to be located according to the first prompt message.

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

[0050] In the above embodiment, when the outdoor unit is in a silent state, the audio device inside the outdoor unit is controlled to issue a first prompt message, which allows maintenance personnel to locate the outdoor unit through the first prompt message, thereby shortening the maintenance time and improving maintenance efficiency.

[0051] In some embodiments, the silent state includes a silent mode state and a silent gear state. The method further includes: when the silent mode state of each outdoor unit in the target multi-split system is in the on state and the silent gear state of each outdoor unit in the target multi-split system is greater than or equal to a preset silent gear, determining that the silent state of each outdoor 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 level 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. Furthermore, when the outdoor unit is in silent mode, its silent level status also needs to be obtained. Different silent levels correspond to different maximum fan speeds and maximum compressor frequencies; the higher the silent level, the quieter the outdoor unit. In the target multi-split air conditioning system, when the silent level status of each outdoor unit is greater than or equal to the preset silent level, the operating sound of each outdoor unit in the target multi-split air conditioning system will not interfere with the audio device, allowing for outdoor unit location.

[0053] For example, assuming the preset silent mode is level 5, the outdoor unit's maximum fan speed is 680 rpm and the maximum frequency is 60 Hz. The maximum fan speed and compressor maximum frequency corresponding to silent modes 1-4 are higher than silent mode 5; the maximum fan speed and compressor maximum frequency corresponding to silent modes 6 and above are lower than silent mode 5.

[0054] In the above embodiments, by determining whether the outdoor unit is in silent mode and whether the silent mode of the outdoor unit meets the preset silent mode, it is determined whether the current silent mode meets the requirements when searching for the outdoor unit.

[0055] In some embodiments, if the silent state of at least one outdoor unit in the target multi-split system does not meet the preset silent conditions, the method further includes: controlling the outdoor unit in the target multi-split system that is in the silent mode off state to turn on the silent mode, and adjusting the silent mode of each outdoor unit in the target multi-split system to the preset silent mode.

[0056] It is understandable that if the outdoor unit's silent state does not meet the preset silent conditions, it may be because the outdoor unit is not in silent mode, or it may be because the outdoor unit's silent setting does not meet the preset silent setting. Therefore, it is necessary to turn on the silent mode of the outdoor unit that is in the off state, and set the silent setting of all outdoor units in the target multi-split system to the preset silent setting, so that the silent state of each outdoor unit in the target multi-split system meets the preset silent conditions.

[0057] It should be noted that adjusting the silent mode of a multi-split air conditioning system will affect its operation. Therefore, if there are multiple multi-split air conditioning systems, user permission must be obtained before adjusting the silent mode of the target system.

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

[0059] Specifically, after the user locates all outdoor units of the system to be located according to the first prompt message, the audio device does not need to continue to issue the first prompt message. Therefore, the audio device of all outdoor units in the system to be located is stopped. In addition, the previous adjustment of the mute state will affect the operation of the multi-split system, so it is also necessary to restore the mute state of each outdoor unit in the target multi-split system to the mute state before the adjustment.

[0060] In the above embodiments, if the mute state of the outdoor unit is adjusted before the control audio device issues the first prompt message, it will affect the operation of the multi-unit system. Therefore, after all the outdoor units in the system to be located are located, the mute state of the outdoor units needs to be restored to the mute state before the adjustment, so that the multi-unit system can return to its previous operation state, which has little impact on the user's comfort.

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

[0062] In other words, the cloud server sends control commands to the audio devices of the corresponding external units of the system to be located through the gateways of all external units of the system to be located at a first preset time interval, so that the audio devices of all external units of the system to be located emit a first prompt message and continue for a first preset time. Taking a buzzer as an example, the buzzer is controlled to run for 'a' seconds, then the buzzer is controlled to stop for 'b' seconds, and then continues for 'c' minutes.

[0063] It should be noted that when there are multiple outdoor units in the system to be located, it is necessary to control the audio devices of all outdoor units to simultaneously issue the first prompt message.

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

[0065] Specifically, the identification identifier can be the indoor unit serial number or outdoor unit serial number of the system to be located. When a multi-split system experiences a malfunction, poor cooling / heating performance, or abnormal noise, resulting in a passive after-sales work order, the user can follow the customer service's guidance to find the indoor unit serial numbers in the affected area, report the problem, and record it. After the user authorizes the activation of proactive after-sales service, the manufacturer generates an after-sales work order, and the cloud server can obtain the outdoor or indoor unit serial numbers. The cloud server then uses the reported indoor or outdoor unit serial numbers to determine the number of multi-split systems in the project and checks whether all systems are powered on.

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

[0067] It is understandable that if there is only one multi-split system, then that multi-split system is the system to be located, and the system to be located is the target multi-split 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 outdoor units in the system to be located to issue a first prompt message according to a second preset time interval within a second preset time period.

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

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

[0071] In other words, after the cloud server sends control commands to the audio devices of the corresponding outdoor units multiple times within a second preset time, if the audio devices of all outdoor units in the system to be located do not issue the first prompt message, the cloud server determines that the audio devices of all outdoor units in the system to be located have failed to execute. Therefore, it issues the second prompt message to remind the user that the audio devices of all outdoor units in the system to be located have failed to execute.

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

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

[0074] Specifically, when there are multiple multi-split systems, the operating sound of the multi-split system located 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. Therefore, it is necessary to identify the system to be located and the multi-split system located in the same working area as the system to be located as the target multi-split system.

[0075] In an alternative implementation, if the working area of ​​the multi-split system in the project has been divided, when determining whether the multi-split system is powered on, only the target multi-split system can be determined, instead of determining whether all multi-split systems are powered on.

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

[0077] like Figure 4 As shown, when there is only one multi-split air conditioning system, the method for locating the outdoor unit of the multi-split air conditioning system includes the following steps:

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

[0079] S402, determine whether the gateway directly connected to the main outdoor unit in the multi-unit system is online. If yes, proceed to step S403; otherwise, proceed to step S412.

[0080] S403, determine whether the multi-split system is in the on state. If yes, proceed to step S404; otherwise, proceed to step S407.

[0081] S404. Determine whether the silent state of each outdoor unit in the multi-split system meets the preset silent conditions. If yes, proceed to step S406; otherwise, proceed to step S405.

[0082] S405, control the outdoor unit in the multi-split system that is in the silent mode off state to turn on the silent mode, and adjust the silent mode of each outdoor unit in the multi-split system to the preset silent mode, and then execute step S406.

[0083] S406, within a first preset time period, control the audio devices of all outdoor units of the multi-unit system to issue a first prompt message according to the first preset time interval.

[0084] S407, within the second preset time period, control the audio devices of all outdoor units in the multi-unit system to issue a first prompt message according to the second preset time interval, and then execute step S408.

[0085] S408, determine whether the audio devices of all outdoor units in the multi-split system have issued the first prompt message. If yes, proceed to step S409; otherwise, proceed to step S411.

[0086] S409 controls all outdoor units in a multi-split air conditioning system to stop emitting the first alert message.

[0087] S410 restores the silent state of each outdoor unit in the multi-split system to its original silent state.

[0088] S411, issue a second prompt message, which indicates that the audio devices of all outdoor units in the multi-unit system have failed to operate.

[0089] S412 indicates that the multi-unit system cannot execute the outdoor unit positioning method.

[0090] In summary, the outdoor unit positioning method for a multi-split air conditioning system according to embodiments of the present invention, when all multi-split air conditioning systems are powered on, determines the target multi-split air conditioning system based on the system to be positioned, obtains the silent state of each outdoor unit in the target multi-split air conditioning system, and, when the silent state of each outdoor unit in the target multi-split air conditioning system meets preset silent conditions, controls the audio devices of all outdoor units in the system to be positioned to issue a first prompt message, so as to locate all outdoor units in the system to be positioned according to the first prompt message. Therefore, when the outdoor unit is in a silent state, by controlling the audio device inside the outdoor unit to issue a first prompt message, maintenance personnel can locate the outdoor unit through the first prompt message, shortening maintenance time and improving maintenance efficiency.

[0091] Corresponding to the above embodiments, embodiments of the present invention also provide a computer-readable storage medium storing a computer program thereon, which, when processed by a processor, executes the outdoor unit positioning method of any of the aforementioned embodiments of the multi-unit system.
