Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more particularly to an air conditioner. Background Technology

[0002] Air conditioners are one of the most commonly used household appliances in modern life, with a wide range of applications in homes, shopping malls, and offices. Functional information records the user's specific controls for the air conditioner, such as silent operation, high-temperature cooling control, priority cooling capacity control, and fan reverse control, allowing users to meet different usage needs by setting different functional information.

[0003] Traditional air conditioner function information is modified via buttons and a central controller. Modifying function information via buttons is set on the air conditioner's main control board, while modifying function information via the central controller is achieved through communication. When the central controller sends a function information setting message, the air conditioner receives this message and modifies the corresponding function information. When function information is modified via buttons, the main control board sends a function information change message, and the central controller can promptly obtain the latest function information.

[0004] With the advancement of air conditioning technology, air conditioners are now equipped with slave devices (such as NFC devices) that communicate with them. Functional information can be set through these slave devices. While the slave device sets this information, the air conditioner only reads or writes messages when the slave device requests them. Therefore, the air conditioner does not proactively send function information change messages to the slave device. Consequently, the slave device cannot obtain function information data in a timely manner; it can only acquire the information when manually triggered. Therefore, the functional information in the slave device cannot always be guaranteed to be consistent with the functional information within the air conditioner. Summary of the Invention

[0005] In response to the problems pointed out in the background art, some embodiments of this application provide an air conditioner that, by setting up at least one central controller that is communicatively connected to the air conditioner and at least one function selection management device that performs master-slave control with the air conditioner, when the central controller or the function selection management device changes the function information, the corresponding function information can be updated synchronously through communication between the two and the air conditioner, ensuring consistency with the function information in the air conditioner.

[0006] To achieve the above-mentioned objectives, the present invention employs the following technical solution: Some embodiments of this application relate to an air conditioner, including: At least one central controller is connected to the outdoor unit for communication. At least one function selection management device communicates with the outdoor unit as a master and slave respectively, and the communication information between each function selection management device and the outdoor unit includes a function flag bit; The processing unit is configured as follows: During the power-on initialization of the air conditioner, synchronize the functional information of the air conditioner, each central controller and each function selection and management device. When the central controller changes the function information, the air conditioner sends a function information change message to the remaining central controllers to update the function information synchronously, and sets the function function flag position in the function information change message sent to all function selection management devices as the first flag bit. When the function selection management device changes the function information, the air conditioner sends a function information change message to all central controllers to update the function information synchronously, and sets the function function flag position in the function information change message sent to the remaining function selection management devices as the first flag bit, the first flag bit indicating that the function information is updated; When each function selection management device reads the function flag bit as the first flag bit, the function information of the corresponding function selection management device is updated synchronously.

[0007] The technical solution of this embodiment has the following beneficial effects or advantages: At least one central controller communicates directly with the air conditioner. Therefore, when the function information is changed on the central controller, it can be directly synchronized to the air conditioner. Furthermore, since at least one function selection management device communicates with the outdoor unit in master-slave mode, when the function information of the air conditioner is changed, the slave device is triggered to read the function information of the air conditioner, thereby achieving synchronization of function information among the central controller, the air conditioner, and the function selection management device.

[0008] In some embodiments of this application, the function selection management device has a data storage device for storing the manufacturing information and function information of the air conditioner. The specific process of powering on and initializing the air conditioner is as follows: After each central controller is successfully connected to the air conditioner, the central controller sends a function information request message to the air conditioner to obtain the function information of the air conditioner's main control board. After the various function selection and management devices are successfully connected to the air conditioner, the manufacturing information of the air conditioner is read and determined; If the read manufacturing information is empty, the function selection management device writes the stored function information into the air conditioner to complete the synchronization of function information; If the read manufacturing information is not empty and the manufacturing information of the function selection management device is empty, the function selection management device reads the function information of the air conditioner and synchronizes it to its data storage. If the manufacturing information read is consistent with the manufacturing information of the function selection management device, synchronization is not required; If the manufacturing information read is not empty and the manufacturing information of the function selection management device is inconsistent with each other, determine which of the main control board and the board of the function selection management device is the board to be replaced by another machine, and update the function information corresponding to the replaced board with the function information corresponding to the unreplaced board.

[0009] The technical solution of this embodiment has the following beneficial effects or advantages: During power-on initialization, the manufacturing information of the air conditioner and the manufacturing information of the function selection management device are matched to confirm that they are compatible air conditioners and function selection management devices, thereby synchronizing the function information of the two.

[0010] In some embodiments of this application, the following features are described: The manufacturing information is either a manufacturing code or model information.

[0011] The technical solution of this embodiment has the following beneficial effects or advantages: The manufacturing information used for matching is selected as manufacturing code or model information, which are hardware information that is not easy to change, making it convenient to match air conditioners and corresponding function selection management equipment.

[0012] In some embodiments of this application, the processing unit is further configured to determine whether the functional information to be changed by the central controller or the functional selection management device is reasonable; If the functional information to be changed is reasonable, the air conditioner changes the functional information and sends a functional information change message; otherwise, the air conditioner does not change the functional information and does not send a functional information change message.

[0013] The technical solution of this embodiment has the following beneficial effects or advantages: By judging whether the functional information to be changed is reasonable, we can avoid malicious or arbitrary changes to the functional information, which could affect the reliability of the air conditioner.

[0014] In some embodiments of this application, different functional information corresponds to different functional data; When the central controller or function selection management device changes the function information, it determines whether the function data corresponding to the function information to be changed is within the specified data range. If so, it means that the function information to be changed is reasonable; otherwise, the function information to be changed is unreasonable.

[0015] The technical solution of this embodiment has the following beneficial effects or advantages: By setting functional data corresponding to functional information and comparing the functional data with the specified data range, the rationality of the functional information to be changed is limited, thus avoiding arbitrary changes to functional information and affecting the reliability of the air conditioner.

[0016] In some embodiments of this application, the processing unit is further configured to perform an information verification process on the air conditioner, specifically: Determine whether the inspection conditions of the air conditioner meet the preset verification conditions. If so, verify the function information of the air conditioner using the function information in the data storage of the function selection device; otherwise, do not verify the function information of the air conditioner.

[0017] The technical solution of this embodiment has the following beneficial effects or advantages: During air conditioner operation, software or hardware issues may cause functional information to suddenly reach abnormal values. Therefore, when the air conditioner's inspection conditions meet the preset inspection conditions, the functional information of the air conditioner can be verified to correct abnormal functional information in a timely manner. Furthermore, recording the abnormal points can help troubleshoot problems and facilitate subsequent air conditioner maintenance.

[0018] In some embodiments of this application, the process of verifying the information of the air conditioner is as follows: If the test conditions of the air conditioner meet the preset verification conditions, the air conditioner sends a function information verification request to the function selection management device and sets the function function flag position in the communication information to the second flag position indicating the verification of function information; When the function selection management device reads the function function flag bit as the second flag bit, the function selection device performs a write operation on the function information; When the functional information in the functional selection management device is consistent with the functional information in the air conditioner, no writing is performed, and the system returns to determine whether the preset verification conditions are met. When the functional information in the functional selection management device is inconsistent with the functional information in the air conditioner, the functional information in the functional selection management device is written into the air conditioner, and the functional information abnormality is recorded.

[0019] The technical solution of this embodiment has the following beneficial effects or advantages: Since the function selection management device and the outdoor unit communicate in a master-slave manner, the read / write frequency in the data storage unit within the function selection management device is low, and the data storage is relatively stable, which can be used for the verification function of the air conditioner's function information.

[0020] When the air conditioner meets the preset verification conditions, the air conditioner triggers the function selection management device. The function information in the function selection management device is used to verify the function information in the air conditioner, preventing unauthorized devices from modifying the air conditioner's function information or causing sudden changes in function information due to software and hardware incompatibility.

[0021] In some embodiments of this application, when there are multiple function selection management devices, each function selection management device has a different priority, and the communication information between the function selection management device and the outdoor unit also includes priority information; When there are multiple function selection management devices and one of the function selection management devices changes its function information, the air conditioner sends a function information change message to all central controllers to update the function information synchronously, and sends a function information change message to other function selection management devices whose priority is not greater than that of the one function selection management device, and sets the function function flag position in the corresponding function information change message to the first flag bit. When the function selection management device reads the function function flag bit as the first flag bit, it synchronously updates the function information of the function selection management.

[0022] The technical solution of this embodiment has the following beneficial effects or advantages: When multiple function selection management devices exist, by setting their corresponding priorities, it is possible to use the function selection management device to synchronize function information, and at the same time, to use the function selection management device with higher priority to manage function information.

[0023] In some embodiments of this application, the preset verification conditions include a first time period verification condition. When multiple function selection management devices exist, the process of verifying the function information of the air conditioner includes the following: S11: Determine whether the priority of the function selection management device for changing function information is the lowest priority. If yes, proceed to S21; otherwise, proceed to S12. S12: Determine whether the priority of the function selection management device for changing function information is the highest priority. If yes, proceed to S31; otherwise, proceed to S13. S13: Determine whether the inspection conditions of the air conditioner meet the inspection conditions of the first time period. If yes, proceed to S14; otherwise, return to S11. S14: The air conditioner sends a function information verification request to other function selection management devices with a priority no greater than that of the function selection management device that changes function information, and proceeds to S15; S15: Determine whether the function information of the other function selection management devices is the same as each other. If yes, proceed to S16; otherwise, proceed to S18. S16: Determine whether the function information of the other function selection management device is consistent with the function information of the air conditioner. If yes, return to S11; otherwise, proceed to S17. S17: Write the function information of the other function selection management device into the air conditioner, record any abnormal function information, and return to S11; S18: The air conditioner sends a function information verification request to the highest priority function selection management device, synchronizes the function information of the highest priority function selection device to the air conditioner, synchronizes it to other function selection management devices, records function information abnormalities, and returns to S11. S21: Determine whether the inspection conditions of the air conditioner meet the inspection conditions of the first time period. If yes, proceed to S22; otherwise, return to S11. S22: The air conditioner sends a function information verification request to the lowest priority function selection management device, and proceeds to S23; S23: Determine whether the function information in the lowest priority function selection management device is consistent with the function information in the air conditioner. If yes, return to S11; otherwise, proceed to S24. S24: Write the function information of the lowest priority function selection management device into the air conditioner, record the function information abnormality, and return to S11; S31: Determine whether the inspection conditions of the air conditioner meet the inspection conditions of the first time period. If yes, proceed to S32; otherwise, return to S11. S32: The air conditioner sends a function information verification request to all function selection management devices and proceeds to S33; S33: Determine whether the function information in all function selection management devices is the same. If yes, proceed to S34; otherwise, proceed to S36. S34: Determine whether the function information of all function selection management devices is consistent with the function information of the air conditioner. If yes, return to S11; otherwise, proceed to S35. S35: Write the function information of the function selection management device into the air conditioner, record any abnormal function information, and return to S11; S36: The air conditioner sends a function information verification request to the highest priority function selection management device, synchronizes the function information of the highest priority function selection device to the air conditioner, synchronizes it to other function selection management devices, records function information abnormalities, and returns to S11.

[0024] The technical solution of this embodiment has the following beneficial effects or advantages: By setting the first time period for verification, the function information of the air conditioner is verified using the function selection management device, thus avoiding the problem of asynchronous function information caused by the function selection management device arbitrarily changing the function information in the air conditioner; and when the function information of the air conditioner is abnormal, the function information is corrected in a timely manner.

[0025] In some embodiments of this application, the preset verification condition further includes at least one second time period verification condition, wherein the duration of each second time period verification condition is longer than that of the first time period verification condition. The number of at least one second time period verification condition is equal to the number of multiple function selection management devices minus 1; the time period of the second time period verification condition corresponding to the function selection management device with higher priority is longer; When multiple function selection management devices exist, the process of verifying the air conditioner's function information also includes the following: S41: Determine whether the inspection conditions of the air conditioner meet the corresponding second time period inspection conditions of any function selection management device with a higher priority than the function selection management device with changed function information. If yes, proceed to S42; otherwise, return to S11. S42: The air conditioner sends a function information verification request to any function selection management device, synchronizes the function information of any function selection management device to the air conditioner, and synchronizes it to other function selection management devices with a lower priority than any function selection management device, and returns to S11.

[0026] The technical solution of this embodiment has the following beneficial effects or advantages: By using at least one second time period verification condition, it is ensured that the functional information in the high-priority functional selection management device is consistent with the functional information in the low-priority management device, and also consistent with the functional information in the air conditioner, thus enabling synchronous management of the functional information in the functional selection management device.

[0027] Some embodiments of this application also relate to an air conditioner, comprising: At least one indoor unit for indoor air conditioning; The outdoor unit communicates with each indoor unit. At least two function selection management devices communicate with the outdoor unit as master and slave respectively, and the communication information between the function selection management devices and the outdoor unit includes a function flag bit; The processing unit is configured as follows: During the power-on initialization of the air conditioner, synchronize the functional information of the air conditioner and each function selection and management device. When a function selection management device changes its function information, the air conditioner sends a function information change message to all function selection management devices, and the function function flag bit in the function information change message is the first flag bit indicating that the function information has been updated. When the function selection management device reads the function function flag bit as the first flag bit, it synchronously updates the function information of the corresponding function selection management device.

[0028] The technical solution of this embodiment has the following beneficial effects or advantages: Since at least one function selection management device communicates with the outdoor unit in master-slave mode, when the air conditioner changes its function information, the slave device is triggered to read the air conditioner's function information, thereby synchronizing the function information of the air conditioner and the function selection management device.

[0038] Air conditioners execute a refrigeration cycle using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle involves a series of processes, including compression, condensation, expansion, and evaporation, to cool or heat an indoor space.

[0039] Low-temperature, low-pressure refrigerant enters the compressor, which compresses it into a high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0040] The expansion valve expands the high-temperature, high-pressure liquid refrigerant that condenses in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0041] The outdoor unit of an air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner includes the indoor heat exchanger, and an expansion valve can be provided in either the indoor or outdoor unit.

[0042] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0043] The outdoor unit of an air conditioner is usually called the outdoor unit, and the indoor unit of an air conditioner is usually called the indoor unit.

[0044] More and more devices connected to air conditioners can modify the air conditioner's functional information. In order to ensure the reliable operation of the air conditioner, when the device modifies the air conditioner's functional information, the functional information of each device should be synchronized to avoid the air conditioner control chaos caused by the asynchrony of functional information.

[0045] In some embodiments of this application, see Figure 1 The device may include a central controller 300 and a function selection management device 400 (e.g., an NFC device). The central controller 300 is used to centrally control the air conditioner, and the central controller 300 communicates with the outdoor unit 100, for example, using Hlink communication, and can communicate directly with the outdoor unit 100. The function selection management device 400 communicates with the outdoor unit 100 in master-slave mode and can change the function information of the air conditioner.

[0046] In some embodiments of this application, when the central controller 300 changes the functional information, it can directly communicate with the outdoor unit 100, that is, achieve direct synchronous change.

[0047] In some embodiments of this application, since the function selection management device 400 and the outdoor unit 100 communicate in master-slave manner, when the function information of the air conditioner changes, the function selection management device 400 needs to synchronize the function information through its communication with the outdoor unit 100. Therefore, the communication information between the outdoor unit 100 and the function selection management device 400 includes a function flag bit.

[0048] When the function information of the air conditioner changes, it actively sends a function information change message to the function selection management device 400, and sets the function function flag in the function information change message to the first flag bit indicating the updated function information (for example, the first flag bit is 1). When the function selection management device 400 reads the function function flag bit which is the first flag bit, it updates its own function information to achieve synchronous update with the function information of the air conditioner.

[0049] In some embodiments of this application, the air conditioner includes at least one central controller 300 and at least one function selection management device 400.

[0050] The functional information of the air conditioner is stored in the air conditioner's memory, the functional information of the central controller 300 is stored in the central controller 300's memory, and the functional information of the function selection management device 400 is stored in its data memory.

[0051] In some embodiments of this application, the air conditioner further includes a processing unit (not shown) for performing synchronous updates of functional information and verification of the functional information of the air conditioner.

[0052] When the air conditioner is powered on and initialized, the functional information of the air conditioner, the central controller 300 and the function selection management device 400 are synchronized.

[0053] After the air conditioner is powered on, its main control program initializes the data and reads the data from the air conditioner's memory.

[0054] After the central controller 300 is successfully connected to the air conditioner, the central controller 300 sends a functional information request message to obtain the functional information of the air conditioner's main control board, thereby synchronizing the functional information of the central controller 300 during the power-on initialization of the air conditioner.

[0055] In some embodiments of this application, in order to synchronize the functional information of the air conditioner and the function selection management device 400 when the air conditioner is powered on and initialized, the air conditioner's memory also stores the air conditioner's manufacturing information (e.g., the manufacturing information of the main control board), and the function selection management device 400's data memory also stores its own board's manufacturing information. The manufacturing information of the air conditioner's main control board matches the manufacturing information of the function selection management device 400's board. Thus, by comparing the manufacturing information of the main control board and the board's manufacturing information, it can be determined whether they belong to the same air conditioning system.

[0056] In some embodiments of this application, after the function selection management device 400 is successfully connected to the air conditioner, it will determine the status of the air conditioner, see [link to relevant documentation]. Figure 2 The specific description is as follows.

[0057] After the various function selection management devices 400 are successfully connected to the air conditioner, the manufacturing information of the air conditioner is read and judged.

[0058] If the manufacturing information of the air conditioner read is empty, it means that the main control board of the air conditioner is a new board. At this time, the function selection management device 400 writes the function information it stores into the air conditioner to complete the synchronization of function information.

[0059] If the manufacturing information of the air conditioner is not empty, and the manufacturing information of the function selection management device 400 is empty, it means that the substrate of the function selection management device 400 is a new substrate. At this time, the function selection management device 400 reads the function information of the air conditioner and synchronizes it to its data memory.

[0060] If the manufacturing information of the air conditioner is not empty, the manufacturing information of the function selection management device 400 is not empty, and the manufacturing information of the air conditioner and the manufacturing information of the function selection management device 400 are consistent, it means that the function selection management device 400 is the device originally matched with the air conditioner. In this case, no synchronization is required.

[0061] If the manufacturing information read and the manufacturing information of the function selection management device 400 are both not empty and are inconsistent with each other, determine which of the main control board and the board of the function selection management device 400 is the board to be replaced by another machine, and update the function information corresponding to the replaced board with the function information corresponding to the unreplaced board.

[0062] In some embodiments of this application, when it is determined that the main control board of the air conditioner is a replacement board of another machine, the function information in the function selection management device 400 needs to be synchronized to the air conditioner. When it is determined that the board of the function selection management device is a replacement board of another machine, the function information of the air conditioner needs to be synchronized to the function selection management device 400.

[0063] This power-on initialization process ensures that the functional information of the central controller 300 and the function selection management device 400 is consistent with the functional information of the air conditioner.

[0064] In some embodiments of this application, the manufacturing information mentioned above may be hardware information that is not easily changed, and may include manufacturing number, model information, etc.

[0065] In some embodiments of this application, during the operation of the air conditioner, the functional information of the air conditioner can be changed by the central controller 300 or the functional selection management device 400, as described in detail below.

[0066] See Figure 1 When an air conditioner includes at least one central controller 300 and at least one function selection management device 400, since the central controller 300 and the function selection management device 400 communicate with the outdoor unit 100 in different ways, the situations in which the function information is changed can be divided into the following types: (1) There is one central controller 300 and at least one function selection management device 400, and one central controller 300 changes the function information; (2) There are multiple central controllers 300 and at least one function selection management device 400, and one central controller 300 changes the function information; (3) There is at least one central controller 300 and at least one function selection management device 400, and one function selection management device 400 changes the function information.

[0067] In some embodiments of this application, the first case is described below.

[0068] When the central controller 300 changes the function information, the central controller 300 sends a function information change message to the air conditioner. After receiving the message, the air conditioner changes the function information.

[0069] The air conditioner sends a function information change message to the function selection management device 400, and sets the function function flag position to the first flag position.

[0070] When each function selection management device 400 reads that its function flag bit is the first flag bit, it changes the function information of its data storage to achieve synchronous change.

[0071] In some embodiments of this application, the second case is described below.

[0072] When the central controller 300 changes the function information, the central controller 300 sends a function information change message to the air conditioner. After receiving the message, the air conditioner changes the function information.

[0073] The air conditioner sends a function information change message to other central controllers 300 to synchronize the function information of other central controllers 300.

[0074] Furthermore, the air conditioner sends a function information change message to the function selection management device 400, and sets the function function flag position as the first flag position.

[0075] When each function selection management device 400 reads that its function flag bit is the first flag bit, it changes the function information of its data storage to achieve synchronous change.

[0076] In some embodiments of this application, the third case is described below.

[0077] When the function selection management device 400 changes the function information, the air conditioner sends a function information change message to all function selection management devices 400 and sets the function function flag position as the first flag position.

[0078] Furthermore, the air conditioner sends a function information change message to all central controllers 300, and synchronously changes the function information of all central controllers 300.

[0079] When each function selection management device 400 reads that its function flag bit is the first flag bit, it changes the function information in its data storage, thereby realizing the synchronous change of the function information of all function selection management devices 400.

[0080] In this way, the functional information of the air conditioner, at least one central controller 300 and at least one function selection and management device 400 can be changed synchronously.

[0081] In some embodiments of this application, see Figure 3 When the air conditioner includes multiple function selection and management devices 400, 400A and 400B, the synchronous change method described above can also be adopted, as follows.

[0082] When one of the function selection management devices 400 / 400A / 400B changes the function information, the air conditioner sends a function information change message to all function selection management devices 400, 400A and 400B, and sets the function function flag position to the first flag position.

[0083] When each function selection management device 400, 400A and 400B reads that its function flag bit is the first flag bit, it changes the function information in its data storage, so as to realize the synchronous change of function information of the air conditioner and multiple function selection management devices 400, 400A and 400B.

[0084] In some embodiments of this application, to avoid unauthorized modification of functional information, see [link to relevant documentation]. Figure 4 The processing unit will also determine whether the functional information to be changed by the central controller 300 or the functional selection management device 400 is reasonable.

[0085] The air conditioner will only change its functional information and send a functional information change message when it is deemed reasonable. Otherwise, the air conditioner will not change its functional information or send a functional information change message. That is, the functional information of the air conditioner will not be changed and other devices will not be synchronized with the functional information.

[0086] In some embodiments of this application, see Figure 5 Functional data can be set for functional information, and corresponding preset data ranges can be set. Different functional information can correspond to different functional data and different specified data ranges.

[0087] If the functional data corresponding to the functional information to be changed is within its specified data range, it indicates that the functional information to be changed is reasonable; otherwise, it is unreasonable.

[0088] During the operation of an air conditioner, functional information may suddenly change to abnormal values ​​due to software or hardware reasons. Therefore, it is necessary to regularly check the functional information of the air conditioner to ensure its reliable operation.

[0089] In order to periodically verify the functional information of air conditioners, preset inspection conditions can be set in advance. When the air conditioner meets the preset inspection conditions, the functional information of the air conditioner will be verified.

[0090] In some embodiments of this application, the preset test condition can be the operating time of the air conditioner, such as 1 hour.

[0091] In some embodiments of this application, the function selection management device has a low read / write frequency and stable data. Therefore, the function information in the function selection management device is used to verify the function information in the air conditioner.

[0092] In some embodiments of this application, see Figure 1 The following explanation will be based on the example of a functional selection management device 400.

[0093] After the central controller 300 or the function selection management device 400 changes the function information, when the air conditioner's inspection conditions meet the preset verification conditions, the air conditioner sends a function information verification request to the function selection management device 400, and sets the function function flag position in the communication information to the second flag bit indicating the verification of function information (for example, the second flag bit is 2).

[0094] When the function selection management device 400 reads the function function flag bit as the second flag bit, the function selection device 400 performs a write operation on the function information.

[0095] If the functional information in the functional selection management device 400 is consistent with the functional information in the air conditioner, no writing is performed, and the system returns to determine whether the preset verification conditions are met.

[0096] When the function information in the function selection management device 400 is inconsistent with the function information in the air conditioner, the function information in the function selection management device 400 is written into the air conditioner and the function information abnormality is recorded.

[0097] This function can prevent unauthorized devices from modifying the air conditioner's functional information or causing sudden changes in functional information due to software and hardware incompatibility.

[0098] In some embodiments of this application, to be in Figure 3 The following explanation uses multiple functional selection management devices 400, 400A, and 400B as examples.

[0099] In some embodiments of this application, after the central controller 300 changes the functional information, when the air conditioner's inspection conditions meet the preset verification conditions, the air conditioner sends a functional information verification request to any functional selection management device 400 / 400A / 400B, and uses the functional information in any functional selection management device 400 to verify the functional information in the air conditioner.

[0100] Alternatively, after the function information is changed by one function selection management device 400, when the air conditioner's inspection conditions meet the preset verification conditions, the air conditioner can send a function information verification request to another function selection management device 400A / 400B, and use the function information in the other function selection management device 400A / 400B to verify the function information in the air conditioner.

[0101] In some embodiments of this application, in order to manage the functional information of different functional selection management devices, priority is set for the functional selection management devices, each functional selection management device has a different priority, and the communication information between the functional selection management device and the outdoor unit 100 also includes priority information.

[0102] In some embodiments of this application, the example is illustrated by having multiple function selection management devices with priority levels (e.g., including function selection management device 400, function selection management device 400A, and function selection management device 400B) and at least one central controller 300.

[0103] The priority of the function selection management device 400, the function selection management device 400A, and the function selection management device 400B decreases in that order.

[0104] In some embodiments of this application, when there are multiple function selection management devices 400 / 400A / 400B with priority levels, and for example, when function selection management device 400A changes its function information, the air conditioner sends a function information change message to all central controllers 300 to synchronously update the function information.

[0105] Furthermore, the function flag bit sent by the air conditioner to other function selection management devices 400A and 400B with a priority no greater than that of the function selection management device 400A is the first flag bit; When the function selection management devices 400A and 400B read the function flag bit as the first flag bit, the function information of the function selection management devices 400A and 400B is updated synchronously.

[0106] In some embodiments of this application, when there are multiple function selection management devices 400 / 400A / 400B with priority levels and, for example, when the function selection management device 400 changes its function information, the air conditioner sends a function information change message to all central controllers 300 to synchronously update the function information.

[0107] Furthermore, the air conditioner sends a function information change message to other function selection management devices 400, 400A, and 400B whose priority is no greater than that of the function selection management device 400, and sets the function function flag bit in the function information change message as the first flag bit.

[0108] When the function selection management devices 400, 400A and 400B read the function flag bit as the first flag bit, the function information of the function selection management devices 400, 400A and 400B is updated synchronously.

[0109] In some embodiments of this application, when there are multiple function selection management devices 400, 400A and 400B with priority levels, the state judgment of the air conditioner during power-on initialization is described as follows.

[0110] The difference from the above judgment that does not involve priority is that if the manufacturing information of the air conditioner read is empty, it means that the main control board of the air conditioner is a new board. At this time, the highest priority function selection management device 400 writes the function information it stores into the air conditioner to complete the synchronization of function information.

[0111] In some embodiments of this application, when there are multiple function selection management devices with priority levels, the function information of the air conditioner can be verified by the function selection management device, and the function information of different function selection management devices can also be managed.

[0112] When the air conditioner meets the preset verification conditions, the functional information of the air conditioner will be verified.

[0113] In some embodiments of this application, the preset verification conditions include a first time period verification condition.

[0114] The first time period verification condition can be the air conditioner's running time, such as 1 hour.

[0115] See below. Figures 6 to 10 This will describe the process of verifying the functional information of air conditioners and managing the functional information of different functional selection management devices.

[0116] The process is divided into three parts: (1) the priority of the function selection management device is changed to the lowest priority, that is, the function selection management device 400B; (2) the priority of the function selection management device is changed to the highest priority, that is, the function selection management device 400; (3) the priority of the function selection management device is changed to be lower than the highest priority and higher than the lowest priority, that is, the function selection management device 400A.

[0117] S11: Determine whether the priority of the function selection management device for changing function information is the lowest priority. If yes, proceed to the first verification mode (i.e., proceed to S21). If no, proceed to S12.

[0118] S12: Determine whether the priority of the function selection management device for changing function information is the highest priority. If yes, proceed to the second verification mode (i.e., proceed to S31). If no, proceed to the second verification mode (i.e., proceed to S13).

[0119] Since the communication information between the air conditioner and the function selection management device contains priority information, the processing unit can determine the priority of the function selection management device that changes the function information.

[0120] When the function selection management device with the lowest priority for changing function information (e.g., function selection management device 400B), the verification process from S21 to S24 is initiated. See [link to relevant documentation]. Figure 8 .

[0121] When the function selection management device with the highest priority for changing function information (e.g., function selection management device 400) enters the verification process from S31 to S36, see [link to relevant documentation]. Figure 9 .

[0122] When the priority of the function selection management device that changes the function information is higher than the lowest but lower than the highest (e.g., function selection management device 400A), the verification process from S12 to S18 is initiated. See [link to relevant documentation]. Figure 7 .

[0123] S13: Determine whether the inspection conditions of the air conditioner meet the inspection conditions of the first time period. If yes, proceed to S14; otherwise, return to S11.

[0124] Determine if the air conditioner has been running for, for example, 1 hour. If so, perform a check; otherwise, return to S11 for a loop check.

[0125] S14: The air conditioner sends a function information verification request to other function selection management devices with a priority no greater than that of the function selection management device that changes function information, and proceeds to S15.

[0126] When, for example, the function selection management device 400A changes the function information, if verification is required, the air conditioner sends a function information verification request to the function selection management devices 400A and 400B.

[0127] S15: Determine whether the function information of other function selection management devices is the same as each other. If yes, proceed to S16; otherwise, proceed to S18.

[0128] For example, determine whether the functional information in functional selection management devices 400A and 400B is the same.

[0129] If they are identical, the functional information of the air conditioner will be verified using the functional information in the functional selection management devices 400A and 400B.

[0130] If they are different, proceed to S18, and use the function information in the low-priority function selection management device (e.g., function selection management device 400) with a higher priority than function selection management device 400A to manage the function information in the low-priority function selection management device.

[0131] S16: Determine whether the function information of other function selection management devices is consistent with the function information of the air conditioner. If yes, return to S11; otherwise, proceed to S17.

[0132] By comparing the functional information in the functional selection management device with the functional information in the air conditioner, the functional information in the air conditioner is verified to avoid abnormal values ​​in the functional information.

[0133] S17: Write the function information of other function selection management devices into the air conditioner, record any function information abnormalities, and return to S11.

[0134] When abnormal values ​​appear in the function information of the air conditioner, it is necessary to use the function information in the function selection management device to correct the function information of the air conditioner to ensure that the air conditioner works reliably.

[0135] Furthermore, recording abnormal functional information allows for timely troubleshooting, which is helpful for the later maintenance of the air conditioner.

[0136] S18: The air conditioner sends a function information verification request to the highest priority function selection management device, synchronizes the function information of the highest priority function selection device to the air conditioner, and synchronizes it to other function selection management devices, and returns to S11.

[0137] The function information in the function selection management device 400 is synchronized to the air conditioner, and any abnormal function information is recorded.

[0138] Furthermore, the functional information in the lower-priority functional selection management devices (e.g., functional selection management devices 400 and 400B) is managed using the functional information in the functional selection management device (e.g., functional selection management device 400) with a higher priority than functional selection management device 400A. In other words, the functional information in functional selection management device 400 is synchronized to functional selection management devices 400A and 400B.

[0139] S21: Determine whether the inspection conditions of the air conditioner meet the inspection conditions of the first time period. If yes, proceed to S22; otherwise, return to S11. When it is determined that the function selection management device with the lowest priority for changing function information (e.g., function selection management device 400B), the verification process from S21 to S24 is initiated.

[0140] In S21, it is determined whether the air conditioner has been running for, for example, 1 hour. If so, a check is performed; otherwise, the process returns to S11 for a loop check.

[0141] S22: The air conditioner sends a function information verification request to the lowest priority function selection management device and proceeds to S23.

[0142] Since the communication information between the air conditioner and the function selection management device contains priority information, the processing unit can determine the priority of the function selection management device that changes the function information.

[0143] S23: Determine whether the function information in the lowest priority function selection management device is consistent with the function information in the air conditioner. If yes, return to S11; otherwise, proceed to S24.

[0144] By comparing the functional information in the lowest priority functional selection management device with the functional information in the air conditioner, the functional information in the air conditioner is verified to avoid abnormal values ​​in the functional information.

[0145] S24: Write the function information of the lowest priority function selection management device into the air conditioner, record the function information abnormality, and return to S11.

[0146] When abnormal values ​​appear in the functional information of the air conditioner, the functional information in the lowest priority functional selection management device needs to be used to correct the functional information in the air conditioner to ensure reliable operation of the air conditioner.

[0147] Furthermore, recording abnormal functional information allows for timely troubleshooting, which is helpful for the later maintenance of the air conditioner.

[0148] S31: Determine whether the inspection conditions of the air conditioner meet the inspection conditions of the first time period. If yes, proceed to S32; otherwise, return to S11.

[0149] When it is determined that the function selection management device with the highest priority for changing function information (e.g., function selection management device 400), the verification process from S31 to S36 is initiated.

[0150] In S31, it is determined whether the air conditioner has been running for, for example, 1 hour. If so, a check is performed; otherwise, the process returns to S11 for a loop check.

[0151] S32: The air conditioner sends a function information verification request to all function selection management devices and proceeds to S33.

[0152] When, for example, the function selection management device 400 changes the function information, if verification is required, the air conditioner sends a function information verification request to the function selection management devices 400, 400A, and 400B.

[0153] S33: Determine whether the function information in all function selection management devices is the same. If yes, proceed to S34; otherwise, proceed to S36.

[0154] For example, determine whether the functional information in the functional selection management devices 400, 400A, and 400B is the same.

[0155] If they are identical, the functional information of the air conditioner will be verified using the functional information in the functional selection management devices 400, 400A, and 400B.

[0156] If they are different, proceed to S36, and use the function information in the highest function selection management device 400 to manage the function information in the low-priority function selection management device.

[0157] S34: Determine whether the function information of all function selection management devices is consistent with the function information of the air conditioner. If yes, return to S11; otherwise, proceed to S35.

[0158] By comparing the functional information in the functional selection management device with the functional information in the air conditioner, the functional information in the air conditioner is verified to avoid abnormal values ​​in the functional information.

[0159] S35: Write the function information of the function selection management device into the air conditioner, record any abnormal function information, and return to S11.

[0160] When abnormal values ​​appear in the function information of the air conditioner, the function information in the function selection management devices 400, 400A and 400B needs to be used to correct the function information of the air conditioner to ensure reliable operation of the air conditioner.

[0161] Furthermore, recording abnormal functional information allows for timely troubleshooting, which is helpful for the later maintenance of the air conditioner.

[0162] S36: The air conditioner sends a function information verification request to the highest priority function selection management device, synchronizes the function information of the highest priority function selection device to the air conditioner, synchronizes it to other function selection management devices, records function information abnormalities, and returns to S11.

[0163] Synchronizing the functional information in the functional selection management device 400 to the air conditioner and recording any abnormal functional information is beneficial for the later maintenance of the air conditioner. It also enables the use of higher-priority functional selection management devices to manage the functional information in lower-priority functional selection management devices, ensuring that the functional information in multiple devices is synchronized and stable with the functional information in the air conditioner.

[0164] It should be noted that, as mentioned above, when sending a function information verification request to the function selection management device, the function flag position in the communication information will be set to the second flag bit.

[0165] When the function selection management device reads the function function flag bit as the second flag bit, the function selection device performs a write operation on the function information.

[0166] To determine whether the function can be written to the air conditioner, the lowest priority function selection management device is selected. If its function information is consistent with the function information inside the air conditioner, no writing is performed; otherwise, writing begins.

[0167] For other function selection management devices with a priority higher than the lowest priority, if their function information is the same, it is determined whether the function information is consistent with the function information inside the air conditioner. If they are consistent, no writing is performed; if they are inconsistent, writing begins.

[0168] In some embodiments of this application, in order to further use the function selection management device to manage function information, the preset verification condition also includes at least one second time period verification condition.

[0169] The first time period verification condition can be the short-term operating time of the air conditioner, and the second time period verification condition can be the long-term operating time of the air conditioner.

[0170] For example, a short-term running time can be, for example, 1 hour; a long-term running time can be, for example, 1 day.

[0171] In some embodiments of this application, the number of at least one second time period verification condition is equal to the number of multiple function selection management devices minus 1, and each second time period verification condition corresponds to each of the other function selection management devices except for the lowest priority function selection management device.

[0172] High-priority functional selection management equipment has a longer second time period inspection condition.

[0173] For example, if there are three function selection management devices 400, 400A and 400B with decreasing priority, a second time period verification condition A' can be set for function selection management device 400, and a second time period verification condition B' can be set for function selection management device 400A.

[0174] In this case, the duration of the second time period test condition A' is longer than that of the second time period test condition B'. For example, the running time of the second time period test condition A' is one week, while the running time of the second time period test condition B' is one day.

[0175] See below. Figure 10 This will describe the process of verifying and managing the functional information of the air conditioner when the inspection conditions of the air conditioner meet the inspection conditions of the second time period.

[0176] S41: Determine whether the inspection conditions of the air conditioner meet the corresponding second time period inspection conditions of any function selection management device with a higher priority than the function selection management device for changing function information. If yes, proceed to S42; otherwise, return to S11.

[0177] As described above, if the function management device for changing function information is 400A, after completing the verification process from S12 to S18 above, it will also determine in real time whether the air conditioner's running time meets the second time period verification condition A' corresponding to the function selection management device 400.

[0178] As described above, if the function management device for changing function information is 400B, after completing the verification process from S21 to S24 above, it will also determine in real time whether the air conditioner's running time meets the second time period verification condition A' corresponding to the function selection management device 400 or the second time period verification condition B' corresponding to the selection management device 400A.

[0179] S42: The air conditioner sends a function information verification request to any of the function selection management devices, synchronizes the function information of any of the function selection management devices to the air conditioner, and synchronizes it to other function selection management devices with a lower priority than any of the function selection management devices, and returns to S11.

[0180] If the second time period inspection condition A' is met, a function information verification request is sent to the function selection management device 400, and the function information in the function selection management device 400 is synchronized to the air conditioner and the function selection management devices 400A and 400B.

[0181] If the second time period inspection condition B' is met, a function information verification request is sent to the function selection management device 400A, and the function information in the function selection management device 400A is synchronized to the air conditioner and the function selection management device 400B.

[0182] By using higher-priority function selection management devices to manage function information in lower-priority function selection management devices, it is easier to manage function information at different levels.

[0183] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0184] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
