Description

Technical Field

[0001] This invention belongs to the field of wireless communication technology, and in particular relates to a method for quickly restoring WiFi configuration parameters. This method enables the rapid writing of the configuration parameters built into the original WiFi module without manual operation after replacing the WiFi module. Background Technology

[0002] With the development of smart technology and the increasing demand for intelligent home appliances, more and more home appliances are integrating WiFi modules to achieve remote control and more intelligent scenarios. However, due to the different cloud platforms (including e-commerce clouds and manufacturer-owned clouds) that WiFi modules connect to, and the different encryption requirements of different cloud platforms for communication modules, even devices of the same type but with different serial numbers may use different keys. This leads to significant differences in the firmware built into WiFi modules, resulting in an increased quantity of materials for the same module. On the one hand, this brings difficulties in material management; on the other hand, it puts pressure on the production and after-sales service of home appliances to distinguish WiFi modules, easily causing the risk of incorrect module installation. The usual solution to the above problems is:

[0003] Manufacturers develop universal WiFi module firmware for WiFi modules connected to the same cloud platform. On the production line, the WiFi modules are connected to the host computer software to establish communication and send different configuration parameters for WiFi modules connected to different cloud platforms and different devices. When a WiFi module of a sold home appliance malfunctions and needs to be replaced, the after-sales personnel usually initiate an application, the technicians assist in writing the WiFi configuration parameters, and then mail it to the after-sales personnel for replacement.

[0004] While this solution achieves standardization of WiFi module materials, it results in low efficiency, poor service timeliness, and negative impact on product user experience when replacing WiFi modules in the after-sales process. Summary of the Invention

[0005] The purpose of this invention is to provide a method for quickly restoring WiFi configuration parameters. By comparing the configuration parameters A transmitted by the WiFi module to the control board with its own WiFi configuration parameters B, the WiFi module configuration parameters can be quickly restored from the backup area. This solves the problems of low efficiency, poor service timeliness, and impact on product user experience in the existing after-sales process of replacing WiFi modules.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention provides a method for quickly restoring WiFi configuration parameters, comprising the following steps:

[0008] Step S1: After the WiFi module successfully writes the configuration parameters at the factory, it immediately transmits the configuration parameters to the connected electronic control board via serial communication. The electronic control board receives the configuration parameters and writes them into its built-in memory.

[0009] Step S2: After the device is powered on for the first time, the WiFi module sends a query command to the control board to check whether the current WiFi configuration parameters have been backed up and stored on the control board.

[0010] Step S3: The electronic control board reads WiFi configuration parameter A from the built-in memory and replies to the WiFi module;

[0011] Step S4: The WiFi module receives the configuration parameter A transmitted by the electronic control board, reads its own WiFi configuration parameter B, and compares the configuration parameter B with A;

[0012] If configuration parameter B is not empty, proceed to step S5;

[0013] If configuration parameter B is empty, then proceed to step S6;

[0014] Step S5: If configuration parameter B is not empty, compare whether configuration parameter B is equal to A;

[0015] If configuration parameter B is equal to A, it indicates that the configuration parameters of the current WiFi module have been successfully backed up on the control board. No processing is required, and both the WiFi module and the control board will switch to the normal serial communication program.

[0016] If configuration parameter B is not equal to A, the configuration parameter stored in the WiFi module shall be used to unify the parameters. The WiFi module sends its own WiFi configuration parameter B to the control board. The control board receives the configuration parameter B, erases the old configuration parameter A that has been stored, and writes the new configuration parameter B. After the writing is successful, both the WiFi module and the control board switch to the normal serial communication program.

[0017] Step S6: If configuration parameter B is empty, it indicates that the current WiFi module is a newly replaced WiFi module. The WiFi module writes the configuration parameter A received from the electronic control board into the specified storage area and feeds back the writing result to the electronic control board. Both the WiFi module and the electronic control board switch to the normal serial communication program.

[0018] As a preferred technical solution, in step S1, the configuration parameters include product serial number, product type key, and device key.

[0019] The present invention has the following beneficial effects:

[0020] This invention achieves rapid restoration of WiFi module configuration parameters from the backup area by comparing the configuration parameters A transmitted by the WiFi module to the control board and reading its own WiFi configuration parameters B. After replacing the WiFi module, the original WiFi module's built-in configuration parameters can be quickly written without manual operation, reducing the difficulty of WiFi module replacement and repair, and improving the efficiency of after-sales service and the user's service experience.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1 As shown, the present invention provides a method for quickly restoring WiFi configuration parameters, comprising the following steps:

[0026] Step S1: After the WiFi module successfully writes the configuration parameters at the factory, it immediately transmits the configuration parameters to the connected electronic control board via serial communication. The electronic control board receives the configuration parameters and writes them into its built-in memory. The configuration parameters typically include: product serial number, product type key, device key, etc. The electronic control board is an existing component of the home appliance that performs dedicated functions.

[0027] Step S2: After the device is powered on for the first time, the WiFi module sends a query command to the control board to check whether the current WiFi configuration parameters have been backed up and stored on the control board.

[0028] Step S3: The electronic control board reads WiFi configuration parameter A from the built-in memory and replies to the WiFi module;

[0029] Step S4: The WiFi module receives the configuration parameter A transmitted by the electronic control board, reads its own WiFi configuration parameter B, and compares the configuration parameter B with A;

[0030] If configuration parameter B is not empty, proceed to step S5;

[0031] If configuration parameter B is empty, then proceed to step S6;

[0032] Step S5: If configuration parameter B is not empty, compare whether configuration parameter B is equal to A;

[0033] If configuration parameter B is equal to A, it indicates that the configuration parameters of the current WiFi module have been successfully backed up on the control board. No processing is required, and both the WiFi module and the control board will switch to the normal serial communication program.

[0034] If configuration parameter B is not equal to A, the configuration parameter stored in the WiFi module shall be used to unify the parameters. The WiFi module sends its own WiFi configuration parameter B to the control board. The control board receives the configuration parameter B, erases the old configuration parameter A that has been stored, and writes the new configuration parameter B. After the writing is successful, both the WiFi module and the control board switch to the normal serial communication program.

[0035] Step S6: If configuration parameter B is empty, it indicates that the current WiFi module is a newly replaced WiFi module. The WiFi module writes the configuration parameter A received from the electronic control board into the specified storage area and feeds back the writing result to the electronic control board. Both the WiFi module and the electronic control board switch to the normal serial communication program.

[0036] Example 1 (Configuration parameter B is not empty)

[0037] After the WiFi module successfully writes the configuration parameters at the factory, it immediately transmits the configuration parameters to the connected electronic control board via serial communication. The electronic control board receives the configuration parameters and writes them into its built-in memory. The configuration parameters are: product serial number "HCL8000100020230102001" and device key "1a2b3c4d5e6f7hfe36f5887a5c0146923db5cZ".

[0038] After the device is powered on for the first time, the WiFi module sends a query command to the control board to check whether the current WiFi configuration parameters have been backed up and stored on the control board.

[0039] The control board reads the WiFi configuration parameters A = {HCL8000100020230102001,1a2b3c4d5e6f7hfe36f5887a5c0146923db5cZ} from the built-in memory and replies to the WiFi module.

[0040] The WiFi module receives configuration parameter A transmitted by the control board and reads its own WiFi configuration parameter B = {HCL8000100020230102001,1a2b3c4d5e6f7hfe36f5887a5c0146923d b5cZ}. It then compares configuration parameter B with A to determine if they are equal. The comparison result is as follows:

[0041] If they are equal, it indicates that the configuration parameters of the current WiFi module have been successfully backed up on the control board. No processing is required, and both the WiFi module and the control board will switch to the normal serial communication program.

[0042] If they are not equal, the configuration parameters stored on the WiFi module shall be used to unify the parameters. The WiFi module sends its own WiFi configuration parameter B to the control board. The control board receives the configuration parameter B, erases the old configuration parameter A that has been stored, and writes the new configuration parameter B. After the writing is successful, both the WiFi module and the control board switch to the normal serial communication program.

[0043] Example 2 (Configuration parameter B is empty)

[0044] After the WiFi module successfully writes the configuration parameters at the factory, it immediately transmits the configuration parameters to the connected electronic control board via serial communication. The electronic control board receives the configuration parameters and writes them into its built-in memory. The configuration parameters are: product serial number "HCL8000100020230102002" and device key "9a8b7c6d5e4f3hfe36f5887a5c0146923db5cZ".

[0045] After the device is powered on for the first time (after replacing the WiFi module), the WiFi module sends a query command to the control board to check whether the current WiFi configuration parameters have been backed up and stored on the control board.

[0046] The electronic control board reads the WiFi configuration parameters A = {HCL8000100020230102002,9a8b7c6d5e4f3hfe36f5887a5c0146923db5cZ} from the built-in memory and replies to the WiFi module.

[0047] The WiFi module receives configuration parameter A transmitted by the electronic control board and reads its own WiFi configuration parameter B = {null}, comparing configuration parameter B with A:

[0048] If configuration parameter B is empty, it indicates that the current WiFi module is a newly replaced WiFi module. The WiFi module writes the configuration parameter A = {HCL8000100020230102002,9a8b7c6d5e4f3hfe36f5887a5c0146923db5cZ} received from the electronic control board into the specified storage area, and feeds back the writing result to the electronic control board. Both the WiFi module and the electronic control board switch to the normal serial communication program.
