When the user selects the permission button, the mobile terminal can receive the operation of the user for allowing the household appliance to be upgraded, namely the operation of the selection permission button, and can send the operation to the cloud server so as to inform the user that the household appliance is allowed to be upgraded.
And S104, the cloud server sends an upgrade permission instruction to the household appliance when receiving the operation, sent by the mobile terminal, of the user for allowing the household appliance to perform upgrade input.
And S105, when the household appliance receives the upgrading permission instruction, sending a version file downloading request to the cloud server, downloading the file of the latest version according to the version file downloading request, and upgrading according to the file of the latest version.
It should be noted that, in an embodiment of the present invention, the home appliance may download the latest version of the file in a frame-by-frame manner.
Specifically, in the embodiment of the present invention, a specific implementation process of upgrading according to the latest version of the file may be as follows: and controlling the household appliance to reset, replacing the file of the original version with the file of the latest version, and controlling the household appliance to operate according to the file of the latest version. That is to say, the home appliance can be controlled to reset, and the firmware program corresponding to the newly updated latest version of the file is skipped to operate, so as to complete the upgrading operation of the home appliance.
According to the control method of the household appliance, the household appliance can send a version query request to the cloud server, the request comprises the current version information of the household appliance, when the cloud server judges that the latest version of the household appliance exists according to the current version information, the cloud server can feed back the latest version information of the latest version to the household appliance and send a push message to the mobile terminal configured with the household appliance to prompt a user whether the household appliance is allowed to be upgraded, and when receiving the operation of the user sent by the mobile terminal aiming at the permission of upgrading input of the household appliance, an upgrade permission instruction is sent to the household appliance to download the version file of the household appliance, and the upgrading is carried out according to the version file after the downloading is finished, so that the remote upgrading function of the household appliance is realized, and the maintenance of the household appliance by the user is convenient, the use and maintenance cost of the household appliance is reduced, the upgrading of the main control software of the household appliance can be completed by the user, the viscosity of the product and the user is improved, and the user experience is improved.
In order to ensure that the upgraded version is correct and that the upgraded version matches the household appliance, the latest version of the file may be checked before being upgraded according to the latest version of the file. Specifically, in one embodiment of the present invention, before the upgrade is performed according to the latest version of the file, the control method of the home appliance may further include: checking the file of the latest version; if the file of the latest version passes the verification, upgrading according to the file of the latest version; and if the latest version of the file is not checked, clearing the number of the successfully downloaded frames. In the embodiment of the present invention, the latest version of the file may be checked by means of CRC32 Check (Cyclic Redundancy Check 32, 32-bit Cyclic Redundancy Check).
It should be noted that the end of the latest version of the file may include the CRC32 check code of the entire file, and the start of the latest version of the file may have address information (i.e. relative to the start of the file), a character string (the length of the character string is fixed) for distinguishing information such as the model of the household appliance to which the latest version of the file is applied. It can be understood that the address information and character string in the beginning of the latest version of the file can be included in the check range of the CRC32, so that the content of the upgrade file downloaded by the household appliance can be ensured to be reliable and the method is suitable for the household appliance.
More specifically, the household appliance may generate a CRC32 check code according to the address information and the character string in the beginning of the latest version of the file, and then match the CRC32 check code with the CRC32 check code included in the latest version of the file, if they are consistent, the latest version of the file may be considered to pass the check; if the files are inconsistent, the latest version of the file is not checked and the content of the file is not reliable, the downloaded frame number can be cleared, and the upgrading is finished.
Further, in an embodiment of the present invention, in the process of downloading the latest version of the file according to the version file download request, the method for controlling the home appliance may further include: when detecting that the downloading process of the latest version of the file is interrupted, saving the number of downloaded frames. Specifically, in the process of downloading the latest version of the file according to the version file download request, if the download process is interrupted, such as the user clicks to pause or cancel the download, or the network is interrupted, the home appliance may save the number of frames that have been downloaded, so as to continue the download next time. Therefore, the function of intermittent continuous transmission is realized, the downloading time of the upgrade file is saved, and the upgrade efficiency is improved.
In the embodiment of the invention, if the latest version of the downloaded file of the household appliance supports breakpoint continuous transmission, whether the downloaded frame number exists needs to be judged before downloading. Specifically, before downloading the latest version of the file according to the version file download request, the control method of the home appliance may further include: judging whether a part of the file of the latest version is downloaded; if yes, acquiring the serial number of a part of the frame numbers, and starting downloading from the next frame number according to the serial number; if not, the download is started from the first frame number of the latest version of the file. That is, before starting downloading, the household appliance may check whether a part of the upgrade file of the version has already been downloaded (possibly, the last downloading is interrupted), and if so, continue downloading from the breakpoint; if not, the download is started.
Specifically, in the embodiment of the present invention, a part of the file of which the latest version has been downloaded can be determined in the following two ways: one way, the number of frames of the latest version can be judged whether the household appliance has the frame number, if yes, a part of the file of the latest version is considered to be downloaded; in another mode, the size of the folder in which the downloaded file is stored in the home appliance may be determined, and if the size is greater than a certain threshold, a part of the file of the latest version is considered to have been downloaded.
It should be noted that, in the embodiment of the present invention, the home appliance downloads the latest version of the file frame by frame, that is, each time the home appliance sends a frame of request, the home appliance needs to wait for the cloud server to respond to the correct home appliance fragment data before sending the next frame of request. If no reply is received over a period of time (e.g., timeout set to 15 s), or the contents of the reply message are incorrect, the home appliance retransmits the download request of the frame, and the number of retransmissions is set to 5 at most. If the correct response message is not received after repeated retransmission, the household appliance exits the downloading process and saves the number of the downloaded file frames.
In order that those skilled in the art will be able to more clearly understand the present invention, the following description will be given by way of example.
For example, fig. 2 is an exemplary diagram of an upgrade process of a home appliance according to an embodiment of the present invention, as shown in fig. 2, the home appliance may first send a query request to the cloud server to query whether an upgrade version of the home appliance exists in the cloud server (S201). The cloud server can judge whether the household appliance is the latest version or not according to the query request (S202), and if so, the process is finished; if not, the cloud server feeds back the latest version information to the household appliance, such as the size of the version file, the number of frames, the version number and the like (S203), and sends a push message to a mobile terminal matched with the household appliance to prompt a user that the household appliance has the latest version, whether upgrading is allowed or not and the like (S204). The cloud server judges whether an operation of allowing upgrading, which is input by a user and sent by the mobile terminal, is received (S205), if not, the upgrading is finished, and if so, the cloud server sends an instruction of allowing upgrading to the household appliance (S206). When receiving the upgrade permission instruction, the home appliance may send a download request to the cloud server to request downloading of the latest version of the file (S207). When the downloading is finished, the household appliance can judge whether the files of the latest version are completely downloaded (S208), if not, the number of successfully downloaded frames is recorded (S209), otherwise, the downloaded files of the latest version are checked (S210), if the checking is not passed, the household appliance clears the number of successfully downloaded frames (S211), and if the checking is passed, the household appliance reports an 'upgrade completion' message to the cloud server and the mobile terminal respectively (S212). Thereafter, the home appliance is restarted and operated according to the latest version of the file to complete the version upgrade of the home appliance (S213).
It can be understood that, in the process of downloading the file of the latest version according to the version file downloading request, the household appliance can support the function of breakpoint continuous transmission, so that before the household appliance downloads the file of the latest version, it is also required to judge whether the breakpoint exists in the latest version, and download the upgrade file frame by frame according to the judgment result. Specifically, as shown in fig. 3, the household appliance may first determine whether there is a part of the file of the latest version downloaded (S301), if so, acquire a sequence number of a frame number in the part, then start downloading from a next frame number according to the sequence number (S302), and if not, start downloading from a first frame number of the file of the latest version (S303). In the downloading process, the household appliance can send a downloading request of a frame number fragment to be downloaded currently to the cloud server (S304), and judge whether correct fragment data responded by the cloud server is received (S305), if so, judge whether the frame number to be downloaded currently is the last frame (S306), if so, download is completed, otherwise, add 1 to the frame number (S307), and return to execute the step S304, that is, enter the downloading process of the next frame; if the correct fragment data responded by the cloud server is not received, the household appliance judges whether the downloading request of the frame number fragment to be downloaded currently is retransmitted for 5 times (S308), if not, the step S304 is returned to be executed, and if so, the downloading is interrupted.
