[0037] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the embodiments of the present invention will be more comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, many specific details are provided to provide a full understanding of the implementation of the embodiments of the present invention.

[0038] Inverter refrigerators use inverter compressors as refrigeration medium compression devices, and drive inverter compressors through inverter drive boards. Since there are many types of compressors now, it is difficult to find compressors of the same model when replacing compressors for after-sales maintenance. The same cop compressor can be used to refresh the compressor parameters in the memory chip of the inverter drive board to complete the repair. In existing after-sales maintenance outlets, the compressor parameter data is generally burned using a computer-controlled burner or burned through an offline burning tool. However, using a computer-controlled burner to burn requires a computer, which is costly, poorly portable, and inconvenient to maintain the compressor parameter data. Burning data through an offline burning tool is easy to carry, but it needs to be sent back to the headquarters regularly to maintain the operating parameters of the new inverter compressor, which greatly reduces the maintenance efficiency.

[0039] To solve the above problems, the first aspect of the embodiment of the present application proposes a cloud storage, upload, and download control method for variable frequency refrigerator compressor parameters, aiming to improve maintenance efficiency, reduce maintenance costs, and realize convenient updating and maintenance of compressor parameters.

[0040] Reference Figure 1 As shown, the method specifically comprises the following steps:

[0041] S100: storing and maintaining the drive configuration characteristic parameters of the variable frequency refrigerator and the corresponding variable frequency compressor parameters in the cloud server.

[0042] The purpose of this step is to establish a centralized and unified data management platform to centrally store and regularly maintain the drive configuration characteristic parameters of all variable frequency refrigerators and their corresponding variable frequency compressor parameters to ensure the accuracy and timeliness of the data.

[0043] S200: Input or select the drive configuration characteristic parameters through the mobile phone APP client, and the mobile phone APP client and the cloud server are connected through wireless communication to download the corresponding compressor parameters.

[0044] This step enables users to input or select the drive configuration characteristic parameters of the variable frequency refrigerator through the mobile phone APP client anytime and anywhere, and quickly download the corresponding compressor parameters from the cloud server through wireless communication connection, which greatly improves the efficiency and convenience of maintenance work.

[0045] S300: The mobile phone APP client controls the burning tooling through wireless communication connection, and transmits the downloaded variable frequency compressor parameter data to the burning tooling.

[0046] Furthermore, through the wireless communication connection between the mobile phone APP client and the burning tooling, the compressor parameters can be quickly transmitted, avoiding the inconvenience and limitations of the traditional wired connection method, and further improving the maintenance efficiency.

[0047] S400: The burning tool burns the downloaded variable frequency compressor parameter data into the storage chip of the variable frequency drive board to complete the data burning. The storage chip is used to drive the variable frequency compressor of the corresponding model according to the variable frequency compressor parameter data.

[0048] The downloaded compressor parameter data is burned accurately and quickly into the storage chip of the variable frequency drive board using the burning tool, so as to achieve accurate driving of the variable frequency compressor and ensure the normal operation of the variable frequency refrigerator. At the same time, since the compressor parameter data is stored in the cloud, it can be updated and maintained at any time, without the need to regularly send it back to the headquarters to maintain the operating parameters of the new variable frequency compressor, which greatly reduces the maintenance cost and time cost.

[0049] To sum up, the cloud storage, upload, and download control method for variable frequency refrigerator compressor parameters proposed in the embodiment of the present application, through cloud storage and maintenance of compressor parameter data, uses a mobile phone APP client to realize fast download and transmission of parameters, and uses a burning tool to realize fast burning of parameters, effectively solves the problems existing in the existing after-sales maintenance outlets in burning compressor parameter data, improves maintenance efficiency, reduces maintenance costs, and realizes convenient updating and maintenance of compressor parameters.

[0050] In some embodiments of the present application, the drive configuration characteristic parameters include compressor model, material code and drive scheme type.

[0051] Specifically, the cloud server stores parameter data by category according to compressor model, material code and drive scheme type. For example, for compressors of different models (such as compressor A, compressor B, etc.), the cloud server establishes independent data storage areas for them. Within each storage area, it is further subdivided according to material code (such as material code 001, material code 002, etc.) and drive scheme type (such as scheme X, scheme Y, etc.) to ensure that each parameter combination has a unique corresponding storage location.

[0052] The compressor model is an important identifier to distinguish different compressors, usually composed of letters and numbers. Compressors of different models have different performance parameters and working characteristics. The material code is a code used to identify the material information of the compressor, usually compiled by the enterprise itself. The material code includes the production batch and supplier information of the compressor. The drive scheme type refers to the type of scheme used to drive the variable frequency compressor, such as "Scheme A", "Scheme B", etc. Different drive scheme types correspond to different control algorithms and parameter settings.

[0053] The drive configuration characteristic parameters include compressor model, material code and drive scheme type, which provide a basis for the unique identification of the variable frequency refrigerator compressor and the selection of the drive scheme. Through these three parameters, by defining a unified drive configuration characteristic parameter standard, compatibility between compressors of different companies and different models is achieved. At the same time, a variable frequency refrigerator compressor and its corresponding drive scheme can be accurately determined, thereby ensuring that the variable frequency drive board can correctly drive the compressor.

[0054] In some embodiments of the present application, in step S200, it also includes:

[0055] Step S210: The mobile APP client includes a driver configuration feature parameter selection list, and the cloud automatically fills in other driver configuration feature parameters when the parameters are entered.

[0056] Specifically, refer to Figure 4As shown, the mobile APP client includes a selection list of drive configuration characteristic parameters, and the user can enter or select the drive configuration characteristic parameters through the selection list. When the user enters any one of the compressor model, material code or drive scheme type in the selection list, the mobile APP client will send part of the input characters to the cloud server for fuzzy matching in real time.

[0057] Secondly, the cloud server searches the database for matching compressor models, material codes or drive scheme types based on the partial characters received, and returns the matching results to the mobile APP client.

[0058] Finally, the mobile APP client presents the matching results returned by the cloud server on the user interface, and the user can select the correct matching item. If the user only enters part of the information, the cloud server can also automatically complete other driver configuration feature parameters based on the existing information.

[0059] In this embodiment, the mobile APP client includes a selection list of drive configuration characteristic parameters, as well as a function of automatic completion in the cloud when inputting parameters, which simplifies the user's operation process and improves the efficiency and accuracy of parameter input. The user only needs to enter or select part of the drive configuration characteristic parameters, and the mobile APP client can automatically complete other parameters and download the corresponding compressor parameters.

[0060] This embodiment is based on fuzzy matching algorithm and database technology, and utilizes the powerful computing power and storage capacity of the cloud server to achieve fast matching and automatic completion of the drive configuration characteristic parameters. The fuzzy matching algorithm improves the efficiency and accuracy of parameter input; the database technology ensures the integrity and accuracy of parameter data. The user only needs to enter or select part of the drive configuration characteristic parameters, and the mobile phone APP client can automatically complete other parameters and download the corresponding compressor parameters, simplifying the operation process. The fast response of the cloud server and the fuzzy matching algorithm improve the efficiency and accuracy of parameter input.

[0061] In some embodiments of the present application, the steps are also included:

[0062] Step S101: When the mobile APP client is started, the cloud server automatically updates the drive configuration feature parameter selection list and synchronizes it to the mobile APP client.

[0063] In order to ensure that the driver configuration feature parameter selection list in the mobile phone APP client is always consistent with the parameter data in the cloud server, this embodiment adds a function of automatically updating the driver configuration feature parameter selection list in the cloud when the mobile phone APP client is started.

[0064] Specifically, when in use, the user starts the mobile APP client of the present invention on the mobile device. During the startup of the mobile APP client, the client will send an update request to the cloud server. After receiving the update request, the cloud server will check whether the driver configuration feature parameter selection list in the local database has been updated. If there is an update, the cloud server will send the latest driver configuration feature parameter selection list to the mobile APP client. After receiving the latest selection list, the mobile APP client will synchronize it to the local and update the selection list on the user interface.

[0065] In this embodiment, the cloud automatically updates the driver configuration feature parameter selection list when the mobile phone APP client is started, ensuring that the selection list in the mobile phone APP client is always consistent with the parameter data in the cloud server. In this way, when the user selects the driver configuration feature parameters on the mobile phone APP client, the latest parameter data can always be obtained, which improves the accuracy and reliability of parameter selection.

[0066] This embodiment uses the powerful computing and storage capabilities of the cloud server to achieve automatic update and synchronization of the driver configuration feature parameter selection list. Furthermore, through the client-server architecture, data interaction between the mobile APP client and the cloud server is achieved; through database synchronization technology, the selection list in the mobile APP client is ensured to be consistent with the parameter data in the cloud server. Users do not need to manually update the selection list, which improves the convenience and efficiency of operation.

[0067] In some embodiments of the present application, reference Figure 3 As shown, the cloud server classifies and maintains the compressor parameters through the operation and maintenance management backend website. The classifications include: compressor model, material code, and drive solution type.

[0068] The operation and maintenance personnel log in to the operation and maintenance management backend website of the cloud server through a computer or mobile device, and choose to add new compressor parameters on the backend website. During the addition process, it is necessary to fill in the compressor model, material code, drive scheme type, and corresponding variable frequency compressor parameter data.

[0069] Operation and maintenance personnel can search for existing compressor parameters on the backend website and perform modification and deletion operations. During the modification process, the compressor model, material code, drive scheme type, and corresponding variable frequency compressor parameter data can be adjusted. During the deletion process, the deletion operation needs to be confirmed to prevent the accidental deletion of important parameter data.

[0070] Furthermore, the cloud server classifies and stores the compressor parameter data according to the operations of the operation and maintenance personnel on the background website. The parameter data is classified according to the compressor model, material code and drive scheme type to ensure that each parameter combination has a unique corresponding storage location.

[0071] The cloud server of this embodiment classifies and maintains the compressor parameters through the operation and maintenance management backend website, and ensures the standardization and consistency of the compressor parameter data through classified storage and management. Through the operation and maintenance management backend website, the operation and maintenance personnel can easily add, modify, delete and other operations on the parameter data, thereby improving the maintenance efficiency and accuracy of the parameter data. At the same time, the operation and maintenance personnel can remotely log in to the backend website to perform parameter maintenance without being restricted by region and time.

[0072] In some embodiments of the present application, the wireless communication connection includes at least one of WiFi, mobile data or Bluetooth communication methods.

[0073] For example, when using WiFi communication, when the mobile APP client and the burning tool are within the coverage of the WiFi network, you can choose WiFi communication to connect. WiFi communication has a high transmission speed and stability, and is suitable for use in fixed places or environments with good network coverage.

[0074] Furthermore, mobile data communication can also be selected. Mobile data communication has greater flexibility and coverage, and is suitable for use in scenarios where the mobile network or network coverage is unstable.

[0075] If the mobile phone APP client and the burning tooling need to communicate at close range, you can choose Bluetooth communication to connect. Bluetooth communication has the characteristics of low power consumption and easy connection, and is suitable for use in scenarios where close distance or low power consumption is required.

[0076] This embodiment improves the flexibility and applicability of the control system by adopting multiple wireless communication methods such as WiFi, mobile data and Bluetooth. In different application scenarios, the most suitable communication method can be selected to ensure the reliability and efficiency of communication.

[0077] In some embodiments of the present application, reference Figure 5 As shown, the burning tool is electrically connected to the burning interface of the variable frequency drive board, and the burning tool includes a Bluetooth module and a pluggable connection terminal with an anti-misinsertion design to adapt to the burning interface of different models of variable frequency drive boards.

[0078] As a parameter data burning device, the burning tooling needs to be electrically connected to the burning interface of the variable frequency drive board to realize the burning of parameter data. The pluggable connection terminal has good electrical performance and mechanical stability to ensure the reliability and durability of the connection.

[0079] Specifically, the pluggable connection terminal of the burning tool is inserted into the burning interface of the variable frequency drive board to achieve electrical connection. During the connection process, the anti-misplugging design ensures the correctness and reliability of the connection and avoids electrical failures caused by misplugging. In addition, the pluggable connection terminal has good mechanical stability and improves the durability of the equipment. Through the pluggable connection terminal, data can be transmitted and burned between the burning tool and the variable frequency drive board.

[0080] The burning tool is electrically connected to the burning interface of the variable frequency drive board to realize the burning of the variable frequency drive board data. The design of pluggable connection terminals improves the reliability and durability of the connection and ensures the smooth progress of the burning process. At the same time, the pluggable design makes the connection and disconnection process easier and faster.

[0081] In some embodiments of the present application, step S300 further includes:

[0082] Step S310: The burning tool provides real-time feedback of burning status and error information through the mobile phone APP client.

[0083] It is understandable that during the burning process, the burning tooling will provide real-time feedback of the burning status and error information through the mobile phone APP client, so that the user can understand the burning process in time. During the burning process, the burning tooling can monitor the burning status in real time, including the burning progress, success or failure, and other information.

[0084] Specifically, the burning tooling feeds back the burning status to the mobile APP client in real time through wireless communication connection. After the mobile APP client receives the burning status information, it will display the current burning progress and status on the user interface. If an abnormality or error occurs during the burning process, the burning tooling will generate a corresponding error message. The burning tooling feeds back the error information to the mobile APP client in real time through wireless communication connection. After the mobile APP client receives the error information, it will display the error information on the user interface so that the user can understand and handle the abnormal situation in time.

[0085] In this embodiment, the burning tooling provides real-time feedback of the burning status and error information through the mobile phone APP client, thereby improving the user's ability to monitor the burning process. The user can promptly understand the burning process based on the feedback information, and handle it in a timely manner when an exception or error occurs, thereby avoiding the consequences caused by untimely handling of the exception. The real-time feedback mechanism also further enhances the user experience, making the entire burning process more transparent and controllable.

[0086] Another aspect of the present application embodiment provides a variable frequency refrigerator compressor parameter storage, upload, and download control system. Figure 2As shown in the figure, the control system consists of four parts: cloud server, mobile APP client, burning tooling and variable frequency drive board. The parts are connected through wireless communication for data transmission and interaction.

[0087] A dedicated database system is built inside the cloud server to store and maintain compressor models, material codes, drive scheme types and corresponding variable frequency compressor parameter data, providing a unified and standardized parameter data source for the entire control system.

[0088] Specifically, the cloud server maintains the stored parameter data through the operation and maintenance management backend website. The operation and maintenance personnel can log in to the backend website to add, modify, delete and other operations on the parameter data. For example, when a new model of compressor is launched, the operation and maintenance personnel can add the drive configuration characteristic parameters of the new compressor and its corresponding variable frequency compressor parameters to the database of the cloud server through the backend website.

[0089] The cloud server stores and maintains the drive configuration characteristic parameters of the variable frequency refrigerator and the corresponding variable frequency compressor parameters, providing a unified and standardized data source for the entire control system. Through the cloud server, centralized management and efficient maintenance of parameter data can be achieved, avoiding the problem of scattered parameter data and difficult maintenance in traditional methods.

[0090] The mobile APP client is used to download the variable frequency compressor parameter data from the cloud server and transmit the parameter data to the burning tooling through wireless communication; it provides an interface for users to input or select the characteristic parameters of the drive configuration. The mobile APP client serves as an interactive interface between the user and the cloud server and the burning tooling to realize the download and transmission of parameter data.

[0091] The burning tooling has a built-in Bluetooth module, which is wirelessly connected to the mobile phone APP client; and is equipped with a pluggable connection terminal, which is electrically connected to the burning interface of the variable frequency drive board; the variable frequency compressor parameter data is burned into the storage chip of the variable frequency drive board.

[0092] Reference Figure 6 As shown, the variable frequency drive board is provided with a storage chip and a burning interface, and the data in the storage chip is read to drive the variable frequency compressor of the corresponding model. As a driving device for the variable frequency refrigerator compressor, the variable frequency drive board can drive the variable frequency compressor of the corresponding model according to the parameter data in the storage chip.

[0093] In some embodiments of the present application, the mobile APP client performs fuzzy matching in real time when the user enters the compressor model.

[0094] In order to improve the efficiency and accuracy of user input of compressor models, the mobile APP client in this embodiment is configured to send part of the input characters to the cloud server for fuzzy matching in real time when the user inputs the compressor model, and display a list of matching compressor models returned by the cloud server for selection.

[0095] In actual use, the user enters partial characters of the compressor model in the compressor model input box of the mobile APP client. The mobile APP client sends the partial characters entered by the user to the cloud server for fuzzy matching in real time. The cloud server searches for matching compressor models in the database based on the received partial characters and returns the matching results to the mobile APP client. The mobile APP client displays the list of matching compressor models returned by the cloud server on the user interface. The user can select the correct compressor model from the matching list, or continue to enter more characters for further matching.

[0096] The mobile APP client performs fuzzy matching in real time when the user enters the compressor model, and displays a matching list for selection, which improves the efficiency and accuracy of the user's input of the compressor model. The user only needs to enter part of the characters of the compressor model to obtain a list of matching compressor models, so as to quickly select the correct compressor model.

[0097] This embodiment is based on fuzzy matching algorithm and database technology, and utilizes the powerful computing power and storage capacity of the cloud server to achieve fast matching and list display of compressor models. The fuzzy matching algorithm improves the efficiency and accuracy of the user inputting the compressor model; the database technology ensures the integrity and accuracy of the compressor model data, making the process of inputting the compressor model more convenient and efficient.

[0098] According to the above embodiments, the present invention provides a method and system for cloud storage, uploading, and downloading control of frequency conversion refrigerator compressor parameters. Through the collaborative work of the cloud server, mobile phone APP client, burning tooling, and frequency conversion drive board, the storage, uploading, downloading, and burning functions of frequency conversion refrigerator compressor parameter data are realized. The cloud server provides storage and maintenance of parameter data; the mobile phone APP client realizes the download and transmission of parameter data; the burning tooling realizes the burning of parameter data; and the frequency conversion drive board drives the compressor according to the parameter data. Centralized management of frequency conversion refrigerator compressor parameter data is realized, which is convenient for operation and maintenance personnel to perform unified maintenance and update. Through the operation and maintenance management backend website, operation and maintenance personnel can easily add, modify, delete, and other operations on parameter data, thereby improving maintenance efficiency.
