Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning equipment control, in particular to a debugging device and an air-conditioning device. Background Art

[0002] Currently, air conditioning units (especially some commercial and industrial-grade air conditioning systems) are affected by environmental factors such as the climate of the region and the installation location of the building. Once the air conditioning unit is operated according to the initial configuration, it is very easy for the configuration information of the air conditioning unit to not match the surrounding environmental factors, which will then trigger an operation alarm of the air conditioning unit, requiring the equipment manufacturer to perform troubleshooting and debugging. Alternatively, if the initial configuration of the air conditioning unit cannot meet the user's personalized needs, the equipment manufacturer is also required to perform personalized debugging. When the equipment manufacturer's operation and maintenance personnel are performing debugging operations, if they encounter a situation where the outdoor unit of the air conditioning unit is located in the outdoor space of a high-rise building, the operation and maintenance personnel need to perform outdoor high-altitude operations to debug and repair the outdoor unit. This makes the operation and maintenance operations not only inconvenient but also relatively dangerous.

[0003] In addition, as current air-conditioning devices are becoming more and more intelligent, the debugging algorithms that need to be configured to realize these intelligent functions are also becoming more and more complex, resulting in the debugging algorithms occupying more and more memory space. Correspondingly, large-capacity storage chips need to be configured on the air-conditioning devices, which in turn increases the cost of the air-conditioning devices. Summary of the Invention

[0014] Further, the data storage module includes a storage medium interface and a removable storage medium, wherein the storage medium interface is connected to the debugging control module;

[0015] The removable storage medium is detachably connected to the storage medium interface and is used to store the debugging record and / or the firmware package.

[0016] Furthermore, the control module is also connected to a display module, and the debugging control module is further used to display the debugging result of the air-conditioning device through the display module after the air-conditioning device is debugged through the communication bus.

[0017] Furthermore, the debugging control module is also connected to a network communication interface, and the network communication interface is used to communicate with a cloud server so as to control and / or perform data analysis on the debugging device through the cloud server.

[0018] Furthermore, the debugging control module is also connected to a data communication interface, and the data communication interface is used to communicate with a third-party device so as to control and / or perform data analysis on the debugging apparatus through the third-party device.

[0019] Furthermore, the debugging device further includes a power supply module, which is connected to a power supply terminal of the debugging control module to supply power to the debugging control module;

[0020] Wherein, the power module includes a battery or a power conversion device.

The debugging device can exchange information with the outdoor unit and each indoor unit via the communication bus to debug the air conditioner and perform software upgrades on the outdoor unit and / or each indoor unit of the air conditioner. Because the debugging device of the present invention only needs to be connected to any indoor unit during debugging of the air conditioner, and does not need to be connected to the outdoor unit of the air conditioner, the problem of inconvenience in debugging and maintaining the outdoor unit of the air conditioner due to the assembly environment can be solved.

[0044] The debugging device provided by the present invention is applicable to an air-conditioning device and is used for debugging and software upgrading the air-conditioning device, wherein the structure of the air-conditioning device is as follows: Figure 1 As shown, it includes an outdoor unit 11 and multiple indoor units 12. The controller of the outdoor unit 11 and the controllers of each indoor unit 12 are connected to the communication bus 10, so that the communication connection between the outdoor unit 11 and each indoor unit 12 is established through the communication bus 10.

[0045] In this embodiment, the communication bus 10 of the air-conditioning device can be a Homebus bus, which is a communication protocol for implementing a home automation system. The outdoor unit 11 and each indoor unit 12 exchange information through the Homebus bus, and control the working status of the outdoor unit 11 and each indoor unit 12 according to the interactive information to control the temperature of the indoor space where each indoor unit 12 is located.

[0046] In this embodiment, a bus communication interface 13 is provided on at least some of the indoor units 12, or on all of the indoor units 12. The outdoor unit 11 may or may not be provided with a bus communication interface 13. The bus communication interface 13 is connected to the communication bus 10 of the air conditioner, and the type of the bus communication interface 13 matches the communication bus of the air conditioner. For example, if the communication bus of the air conditioner is a Homebus bus, the bus communication interface 13 is a Homebus bus interface. The bus communication interface 13 is used to connect to the debugging device. After the adjustment device is connected to any of the bus communication interfaces 13, the adjustment device is connected to the communication bus 10 of the air conditioner and can exchange information with the outdoor unit 11 and each indoor unit 12 via the communication bus 10 of the air conditioner.

[0047] The structure and working principle of the debugging device of the present invention are described in detail below in conjunction with specific application scenarios.

[0048] In one embodiment of the present invention, the debugging device of the present invention is as follows Figure 2 As shown, the debugging device includes a debugging interface 21 and a debugging control module 22 , and the debugging control module 22 is connected to the debugging interface 21 . The debugging control module 22 can send and receive data through the debugging interface 21 .

[0049] The debugging interface 21 of the debugging device is a communication interface corresponding to the aforementioned bus communication interface 12. For example, if the air conditioner's communication bus 10 is a Homebus bus, the debugging interface 21 is a Homebus bus interface corresponding to the bus communication interface 13. The debugging interface 21 is used to connect to the bus communication interface 13 on the outdoor unit 11 or the indoor unit 12. After the debugging interface 21 is connected to one of the bus communication interfaces 13, the debugging device can be connected to the air conditioner's communication bus 10 to establish a communication connection between the debugging device and the outdoor unit 11 and each indoor unit 12.

[0050] The debugging control module 22 can be implemented using a logic controller with data processing and data storage functions, such as a single-chip microcomputer or a CPU. In this embodiment, the debugging control module 22 stores at least one preset debugging algorithm. After the debugging interface 21 is connected to the communication bus of the air conditioner via the bus communication interface 12 on the outdoor unit 11 and the indoor unit 12, the debugging control module 22 can exchange information with the outdoor unit 11 and each indoor unit 12 via the communication bus to debug the air conditioner or perform software upgrades on the outdoor unit 11 and each indoor unit 12.

[0051] The debugging device provided in this embodiment has the following usage and working principles:

[0052] If the air-conditioning device needs to be debugged or the software needs to be upgraded, the staff will select a method that is convenient for testing based on the assembly method of the outdoor unit 11 and the indoor unit 12 in the air-conditioning device, and connect the debugging interface 21 of the debugging device to the bus communication interface 12 on the outdoor unit 11, or to the bus communication interface 12 of one of the indoor units 12, so that the debugging interface 21 is communicatively connected with the communication bus 10 of the air-conditioning device, and the debugging device is connected to the communication bus of the air-conditioning device.

[0053] After the debugging device is connected to the communication bus of the air-conditioning device, the debugging control module 22 can exchange information with the outdoor unit 11 and each indoor unit 12 through the communication bus to obtain the data required for debugging the air-conditioning device from the outdoor unit 11 and each indoor unit 12, and then calculate the obtained data according to the stored preset debugging method to debug the air-conditioning device.

[0054] Alternatively, after the debugging device is connected to the communication bus of the air-conditioning device, the debugging control module 22 sends the firmware package that needs to be upgraded for the outdoor unit 11 to the outdoor unit 11, and / or sends the firmware package that needs to be upgraded for the indoor unit 12 to each indoor unit 12 through the communication bus of the air-conditioning device. After receiving the firmware package, the outdoor unit 11 or the indoor unit 12 performs an OTA (Over-the-Air technology) upgrade on the corresponding software according to the firmware package.

[0055] As can be seen from the foregoing, the technical solution provided by this embodiment provides a debugging device suitable for an air conditioning system, and the debugging device is independent of the air conditioning system. The debugging device of this embodiment can be connected to the communication bus of the air conditioning system via any indoor unit 12, thereby establishing a communication connection between the debugging device and the outdoor unit 11 and each indoor unit 12 via the communication bus. This allows the debugging device to exchange information with the outdoor unit 11 and each indoor unit 12 via the communication bus to debug the air conditioning system and perform software upgrades on the outdoor unit 11 and / or each indoor unit 12 of the air conditioning system. Because the debugging device of this embodiment only needs to be connected to any indoor unit during debugging of the air conditioning system, and does not need to be connected to the outdoor unit 11 of the air conditioning system, the problem of inconvenience in debugging and maintaining the outdoor unit 11 of the air conditioning system due to its assembly environment can be resolved.

[0056] Furthermore, in this embodiment, the preset debugging algorithm used to debug the air conditioner is stored in the debugging control module 22. Therefore, the air conditioner no longer needs to store the preset debugging algorithm. This reduces the amount of program data in the air conditioner, allowing the air conditioner to use a small-capacity chip, thereby reducing the cost of the air conditioner. Furthermore, the debugging device of this embodiment is reusable, meaning that a single debugging device can be used repeatedly to debug and upgrade the software of multiple air conditioners, further reducing the total cost of debugging and upgrading the software of the air conditioner.

[0057] In some embodiments of the present invention, the preset debugging algorithm stored in the debugging control module 22 in the debugging device is an algorithm for calculating the pipe length, an algorithm for calculating the refrigerant injection rate, or an algorithm for setting defrost-related parameters.

[0058] In this embodiment, the debugging control module 22 stores at least one preset debugging algorithm. Specifically, the debugging control module 22 stores one or more of an algorithm for calculating piping length, an algorithm for calculating refrigerant injection rate, or an algorithm for setting defrost-related parameters. During the debugging process of the air conditioner, each preset debugging algorithm can be called sequentially in a predetermined order to debug the air conditioner.

[0059] The algorithm for calculating the piping length is an algorithm for calculating the length of the refrigerant pipe in the air conditioning system, that is, the length of the copper pipe connecting each indoor unit 12 to the outdoor unit 11. In this embodiment, the algorithm for calculating the piping length can use the equivalent length method, that is, based on the layout and parameters of the refrigerant pipe in the air conditioning system, the refrigerant pipe from each indoor unit 12 to the outdoor unit 11 is simplified into a refrigerant pipe of equivalent length to calculate the piping length of the air conditioning system. After calculating the piping length of the air conditioning system, the relevant parameters of the outdoor unit 11 and the indoor unit 12 of the air conditioning system are set according to the piping length, such as setting the compressor power to control the flow rate of the refrigerant in the piping.

[0060] The algorithm for calculating the refrigerant charge rate is a method for calculating the ratio between the refrigerant charge volume of an air conditioner and the standard charge volume specified by the air conditioner manufacturer. If the refrigerant charge rate is too high, it may cause excessive pressure in the air conditioner, increasing energy consumption and the failure rate. If the refrigerant charge rate is too low, it may lead to insufficient cooling performance, affecting the performance of the air conditioner. After the refrigerant charge rate is calculated, it is displayed on a digital tube for staff to view.

[0061] The above-mentioned algorithm for setting defrost-related parameters refers to a method for calculating the defrost duration, defrost interval, defrost temperature and defrost mode of the air-conditioning device. It is necessary to select whether to enhance the defrost function based on the use environment of the air-conditioning device, such as the region where the air-conditioning device is installed, and set the configuration parameters of the air-conditioning device according to the required defrost intensity, such as setting the defrost duration, compressor power, and temperature threshold for defrost start.

[0062] Through the technical solution of this embodiment, the debugging control module 22 can calculate the piping length, refrigerant injection rate and related parameters for setting the defrost of the air-conditioning device during the process of debugging the air-conditioning device according to the preset debugging algorithm, so as to perform comprehensive debugging of the air-conditioning device and improve the reliability of the debugging of the air-conditioning device.

[0063] In some embodiments of the present invention, Figure 3 As shown, the debugging control module 22 of the debugging device is also connected to a function selection module 23, and the user can select a debugging mode through the function selection module 23. The debugging control module 22 can obtain the function selected by the user through the function selection module 23 and debug the air conditioning device or upgrade the software according to the function selected by the user.

[0064] In this embodiment, the function selection module 23 can be implemented using multiple function buttons, where the multiple function buttons include a button corresponding to the software upgrade function and a debugging function button corresponding to each preset debugging algorithm. In other embodiments, the function selection module 23 can be implemented using a touch screen, and the touch screen interface is provided with multiple function virtual buttons for the user to select the corresponding function.

[0065] Assuming that the function buttons on the function selection module 23 include a button corresponding to the outdoor software upgrade function, a button corresponding to the indoor software upgrade function, a button corresponding to the pipe length identification function, a button corresponding to the refrigerant injection rate function, and a button corresponding to the defrost parameter setting function, the process of using the debugging device to debug or upgrade the software of the air-conditioning device in this embodiment is as follows: Figure 4 Shown, including:

[0066] The debugging control module 22 detects the function key operated by the user on the function selection module 23, and obtains the function selected by the user according to the function key operated by the user;

[0067] If the function selected by the user is to upgrade the outdoor unit software, the debugging control module 22 retrieves the firmware package required for the outdoor unit 11 software upgrade and sends the firmware package to the outdoor unit 11 via the communication bus 10 of the air conditioner. After receiving the firmware package, the controller of the outdoor unit 11 upgrades the software of the outdoor unit 11 according to the firmware package.

[0068] If the function selected by the user is indoor unit software upgrade, the debugging control module 22 retrieves the firmware package required for the indoor unit 12 software upgrade and sends the firmware package to each indoor unit 12 via the communication bus 10 of the air conditioner. After receiving the firmware package, the controller of each indoor unit 12 upgrades the software of the corresponding indoor unit 12 according to the firmware package.

[0069] If the function selected by the user is pipe length identification, the debugging control module 22 sends a corresponding data request instruction to the outdoor unit 11 and each indoor unit 12 via the communication bus 10 of the air conditioner to obtain data for calculating the pipe length of the air conditioner from the outdoor unit 11 and each indoor unit 12; then, the stored algorithm for calculating the pipe length is called to calculate the pipe length of the air conditioner;

[0070] If the function selected by the user is to calculate the refrigerant filling rate, the debugging control module 22 sends a corresponding data request instruction to the outdoor unit 11 and each indoor unit 12 through the communication bus 10 of the air conditioner to obtain data for calculating the refrigerant filling rate of the air conditioner from the outdoor unit 11 and each indoor unit 12; then, the stored algorithm for calculating the refrigerant filling rate is called to calculate the refrigerant filling rate of the air conditioner;

[0071] If the function selected by the user is to set the defrost parameters, the debugging control module 22 sends corresponding data request instructions to the outdoor unit 11 and each indoor unit 12 through the communication bus 10 of the air-conditioning device to obtain data for calculating the defrost parameters of the air-conditioning device from the outdoor unit 11 and each indoor unit 12; then the stored algorithm for setting defrost-related parameters is called to calculate the defrost configuration parameters of the air-conditioning device.

[0072] Through the technical solution of this embodiment, the user can select the debugging function and the upgrading function of the air-conditioning device through the function selection module 23, so as to improve the controllability of the debugging device during the process of debugging and software upgrading the air-conditioning device using the debugging device.

[0073] In some embodiments of the present invention, Figure 5 As shown, the debugging device is further provided with a Bluetooth interface 24 , which is used to assemble an external Bluetooth module, and the debugging control module 22 is connected to the Bluetooth interface 24 .

[0074] In this embodiment, the Bluetooth interface 24 can be implemented as a USB interface, and the external Bluetooth module can also be installed on an external device equipped with a USB interface, so that the external Bluetooth module can be plugged into the Bluetooth interface 24 of the configuration device via the USB interface. Furthermore, when the external Bluetooth module is plugged into the Bluetooth interface 24, the debugging control module 22 can connect to the external Bluetooth module to transmit and receive data via the external Bluetooth module.

[0075] Correspondingly, the outdoor unit 11 of the air conditioner is provided with an applied Bluetooth module, which can establish a communication connection with the external Bluetooth module connected to the Bluetooth interface 24 , so that the debugging control module 22 of the debugging device can directly exchange information with the outdoor unit 11 .

[0076] After the debugging device establishes a communication connection with the outdoor unit 11 through the Bluetooth module installed on the Bluetooth interface 24, the debugging control module 22 can send a firmware package to the outdoor unit 11 through the Bluetooth module installed on the Bluetooth interface 24 to upgrade the software of the outdoor unit 11; or interact with the outdoor unit 11 to debug and repair the outdoor unit 11.

[0077] Through the implementation of this embodiment, a communication connection can be established with the outdoor unit 11 through the Bluetooth interface 24 on the debugging device, so that the software of the outdoor unit 11 of the air-conditioning device can be upgraded and debugged without connecting to the communication bus 10 in the air-conditioning device, so as to achieve the purpose of improving the reliability of debugging and software upgrading of the air-conditioning device.

[0078] In some embodiments of the present invention, the debugging control module 22 of the debugging device is further configured to generate a debugging record of the air-conditioning device after debugging the air-conditioning device.

[0079] In this embodiment, the debugging record of the air-conditioning device generated includes the parameter configuration of the air-conditioning device during the debugging process, for example, the piping length calculated during the debugging process, and the power of the compressor set according to the piping length; or the set defrost parameters of the air-conditioning device; or the calculated refrigerant injection rate of the air-conditioning device.

[0080] Through the technical solution of this embodiment, a corresponding debugging record can be generated after the air-conditioning device is debugged, so that the staff can check it later.

[0081] In some embodiments of the present invention, Figure 6 As shown, the debugging control module 22 is also connected to a data storage module 25, which is used to store debugging records of the air-conditioning device and / or store firmware packages required for software upgrades of the indoor unit 12 and / or outdoor unit 11 in the air-conditioning device.

[0082] Through the implementation of this embodiment, debugging records of the air conditioner can be stored in the debugging device's data storage module 25, making them easier for staff to review later. Furthermore, this embodiment also stores the firmware packages required for software upgrades of the indoor unit 12 and / or outdoor unit 11 of the air conditioner in the data storage module 25. Therefore, when using the debugging device to upgrade the software of different air conditioners, the corresponding firmware packages can be directly retrieved from the data storage module 25, thereby improving the reusability of the debugging device.

[0083] In some embodiments of the present invention, the data storage module 25 includes a storage medium interface and a removable storage medium, wherein the storage medium interface is connected to the debugging control module 22, the removable storage medium is used to store debugging records of the air-conditioning device, and the firmware package required for software upgrades of the outdoor unit 11 and / or the indoor unit 12, and the storage medium interface and the removable storage medium are detachably connected.

[0084] In this embodiment, when the removable storage medium is mounted on the storage medium interface, the debugging control module 22 can store data in the removable storage medium through the storage medium interface, or read data from the removable storage medium through the storage medium interface.

[0085] After debugging the air conditioner using the debugging device, the debugging control module 22 can store the debugging record of the air conditioner in a removable storage medium. In this embodiment, the firmware package required for upgrading the software of the outdoor unit 11 and / or the indoor unit 12 can also be stored in the removable storage medium. During the software upgrade process of the outdoor unit 11 or the indoor unit 12, the debugging control module 22 can read the corresponding firmware package from the removable storage medium and send the read firmware package to the outdoor unit 11 or the indoor unit 12 via the communication bus of the air conditioner to upgrade the software of the outdoor unit 11 or the indoor unit 12.

[0086] In this embodiment, the storage medium interface may be an SD card interface, the removable storage medium may be an SD card, and the SD card may be removably mounted in the SD card interface. In other embodiments, the storage medium interface and the removable storage medium may be implemented in other ways. For example, the storage medium interface may be a USB interface, and the removable storage medium may be a storage medium that can be plugged into the USB interface, such as a USB flash drive.

[0087] In this embodiment, the data storage module 25 is configured as a storage medium interface and a removable storage medium. When another device needs to read the data stored in the data storage module 25, for example, when reading the debugging log of the air conditioner, the removable storage medium is removed and inserted into the other device, and the other device can read the data stored in the data storage module 25. Similarly, when another device needs to update the data stored in the data storage module 25, for example, when updating the stored firmware package, the removable storage medium is removed and inserted into the other device, and the other device can update the data stored in the data storage module 25.

[0088] It can be seen from the above content that the technical solution of this embodiment can improve the convenience of data updating and data reading of the data storage module 25.

[0089] In some embodiments of the present invention, a display module is also provided on the debugging device, and the debugging control module 22 is connected to the display module. After debugging the air-conditioning device according to a preset debugging algorithm, the debugging control module 22 displays the debugging results of the air-conditioning device through the display module.

[0090] In this embodiment, the display module on the debugging device can be a liquid crystal display or a digital tube. After the debugging control module 22 debugs the air conditioner, the debugging results displayed on the display module can include the calculated piping length, refrigerant injection rate, and set defrost parameters of the air conditioner, so that the staff can directly view the debugging results of the air conditioner on the debugging device, thereby improving the convenience of debugging the device.

[0091] In some embodiments of the present invention, Figure 7 As shown, the debugging control module 22 is also connected to a network communication interface 26. This network communication interface 26 can be a wired communication interface, such as a broadband network interface, which can be connected to the network via a network cable to establish a communication connection with the cloud server. The network communication interface can also be an interface for connecting to an external network communication module, so as to connect to the cloud server through the external network communication module to control the debugging device or perform data analysis through the cloud server.

[0092] In this embodiment, the external network communication module connected to the network communication interface 26 may be a wireless communication module, such as a WIFI module. The debugging control module 22 may communicate with the cloud server through the external network communication module to exchange information with the cloud server.

[0093] After the debugging control module 22 is connected to the cloud server via the network communication interface 26, it can send data from the debugging process of the air conditioning unit to the cloud server. For example, it can send debugging data obtained from the outdoor unit 11 and each indoor unit 12, as well as the preset debugging algorithm used for debugging, to the cloud server. The cloud server performs calculations based on the received data and the preset debugging algorithm to obtain the debugging results of the air conditioning unit and sends the debugging results to the debugging control module 22. Alternatively, the cloud server can send debugging instructions or software upgrade instructions to the debugging control module 22 of the air conditioner. After receiving the debugging instructions, the debugging control module 22 debugs the air conditioning unit according to the debugging instructions. Alternatively, after receiving the software upgrade instructions, the debugging control module 22 can upgrade the software of the indoor unit 12 or outdoor unit 11 of the air conditioner according to the software upgrade instructions.

[0094] Through the technical solution of this embodiment, a communication connection between the debugging device and the cloud server can be established through the network communication interface 26, so that the cloud server can be used to control the debugging device or perform data analysis, thereby improving the controllability of the debugging device.

[0095] In some embodiments of the present invention, Figure 8 As shown, the debugging control module 22 is also connected to a data communication interface 27, which is used to communicate with a third-party device. The third-party device can exchange information with the debugging control module 22 through the data communication interface 27 to control the debugging device and / or perform data analysis.

[0096] In this embodiment, the data communication interface 27 can be an RS485 interface, and the debugging control module 22 can be connected to a third-party device, such as a host computer or an industrial computer, via the data communication interface 27. After the debugging control module 22 communicates with the third-party device via the data communication interface 27, it can send data related to the debugging process of the air conditioner to the third-party device. For example, the debugging data obtained from the outdoor unit 11 and each indoor unit 12, as well as the preset debugging algorithm used for debugging, can be sent to the third-party device. The third-party device performs calculations based on the received data and the preset debugging algorithm to obtain the debugging results of the air conditioner, and then sends the debugging results to the debugging control module 22. Alternatively, the third-party device can send debugging instructions or software upgrade instructions to the debugging control module 22 of the air conditioner. After receiving the debugging instructions, the debugging control module 22 debugs the air conditioner according to the debugging instructions. Alternatively, after receiving the software upgrade instructions, the debugging control module 22 can upgrade the software of the indoor unit 12 or outdoor unit 11 of the air conditioner according to the software upgrade instructions.

[0097] Through the technical solution of this embodiment, a communication connection between the debugging device and a third-party device can be established through the data communication interface 27, so that the third-party device can be used to control the debugging device or perform data analysis, thereby improving the controllability of the debugging device.

[0098] The adjustment device in each of the above-described embodiments may be provided with a power interface, which is connected to the power supply terminal of the debugging control module 22. The power interface can be connected to an external power source to power the debugging control module 22. Since the debugging control module 22 is a weak current device that requires low-voltage direct current (DC), the external power source connected to the power interface can be a power source that directly provides low-voltage DC power, or a device that can convert AC power into low-voltage DC power, such as a conventional power adapter.

[0099] In some embodiments of the present invention, the regulating device is further provided with a power supply module 20, such as Figure 9 As shown, the power supply module 20 is connected to the power supply terminal of the debugging control module 22 to supply power to the debugging control module 22 .

[0100] In this embodiment, the power module 20 may be a battery, which is connected to the power supply terminal of the debugging control module 22 to supply power to the debugging control module 22. In other embodiments, the power module 20 may include a power conversion device. For example, the power conversion device may include a transformer and a rectifier, wherein the transformer is used to convert the mains power into low-voltage alternating current (AC) power, and the rectifier is used to convert the low-voltage AC power into the low-voltage DC power required for the operation of the debugging control module 22.

[0101] Through the technical solution of this embodiment, if the power module 20 adopts a battery, the operation of the debugging device will not be restricted by the external power supply, thereby achieving the purpose of improving the flexibility of the debugging device; if the power module 20 adopts a power conversion device, the debugging device can use AC power to work without the need for additional power conversion equipment, thereby achieving the purpose of improving the convenience of using the debugging device.

[0102] In some embodiments of the present invention, the present invention further provides an air conditioning device, the structure of which is as follows: Figure 1 As shown above, due to Figure 1 The air conditioning device shown has been introduced in detail, and in order to avoid redundancy, no further description is given in this embodiment.

[0103] Furthermore, in some embodiments of the present invention, Figure 10 As shown, a Bluetooth module 14 is also provided on the outdoor unit 11 of the air-conditioning device. The Bluetooth module 14 is connected to the controller of the outdoor unit 11 and is used to communicate with the external Bluetooth module assembled on the Bluetooth interface 24 on the debugging device to perform software upgrades and / or debugging on the outdoor unit 11 according to the debugging device.

[0104] In summary, the technical solution provided by the present invention allows a worker to connect a debugging device to the air conditioner's communication bus 10 on the air conditioner's indoor unit 12 to debug and upgrade the entire air conditioner. This process eliminates the need for the worker to collect data from the air conditioner or perform dangerous outdoor operations, thereby providing convenient debugging and software upgrades for the air conditioner. Furthermore, the technical solution of the present invention stores a preset debugging algorithm for debugging the air conditioner in the debugging control module 22 of the debugging device. This not only reduces the amount of program data in the air conditioner and lowers the cost of the air conditioner, but also allows for reuse of the debugging device, reducing the overall cost of debugging and software upgrades for the air conditioner.

[0105] At this point, those skilled in the art will recognize that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
