Specifically, as shown in fig. 5, the device side first checks whether a user is operating the device, and if the user is operating the device, starts a downloading program after waiting for the user to operate the device; and when the device side detects that the device is in an idle state, starting a downloading program.
As shown in fig. 5, after the downloading program is started, the condition that whether the current downloading environment meets the downloading requirement needs to be further determined includes: specifically, whether the downloading is the first downloading is judged; judging whether the last downloading is interrupted or not; and judging whether the last downloading step length is smaller than a first preset value or not. The steps of the downloading condition judgment are not in sequence. For example, the first threshold is preferably 5M.
As shown in fig. 5, the step of generating the download configuration parameters according to the corresponding satisfied download conditions after determining whether the current download environment satisfies the download conditions includes: if the downloading is the initial downloading, the downloading configuration parameters are set to be the second preset value (preferably 1M) of the downloading step length and the first preset time (preferably 30s) of the duration; if the downloading is not the initial downloading, further judging whether the last downloading is interrupted; if the interruption is caused, the downloading configuration parameter is set to be the second preset value of the downloading step length, and the duration time is the first preset time; if not, judging whether the last downloading step length is smaller than a first preset value; if the download configuration parameter is smaller than the first preset value, setting the download configuration parameter as the last download step length plus a third preset value (preferably 1M), and setting the duration as the last download time plus a second preset time (preferably 30 s); if the download configuration parameter is not less than the first predetermined value, the download configuration parameter is set to a fourth predetermined value (preferably 5M) for a third predetermined time (preferably 150 s).
Specifically, if during the first download, the download is not interrupted (i.e., there is no user operating the device, and the download of the fixed-step data (1M) is completed within a fixed duration, and after the download is completed, the user sleeps for 10 seconds; the download step for the second time is increased by 1M based on the last download step (1M), and the duration is also increased by 30s based on the last duration (30s), and after the download is completed, the user sleeps for 10s, and so on, until the download step is increased to 5M, and the duration is increased to 150s, and then the download step is pressed by 5M and the duration is 150s, so as to download the firmware until the download is completed or interrupted (i.e., there is a user operating the device, or the download of the fixed-step data is not completed within the fixed duration).
As shown in fig. 5 and 6, the step of downloading the firmware file specifically includes: generating a downloading request according to the downloading configuration parameters and sending the downloading request to the server; the server side verifies the downloading request and executes downloading; judging the size of the downloaded file; and after downloading the file with the preset size, sleeping, returning to the step of judging the use state of the equipment for continuous downloading at preset time, and repeating the steps until the new firmware is completely downloaded.
Specifically, as shown in fig. 5, the server verifying the download request and executing the download includes: verifying whether the download authorization code is valid; if the authorization code is invalid, feeding back an illegal user message to the user terminal; if the authorization code is valid, judging whether the downloading step length and the downloading position are valid; if the downloading step length and the downloading position are valid, the terminal continues to transmit the downloading; otherwise, the re-downloading message is fed back to the user terminal.
As shown in fig. 5, in the embodiment of the present invention, during the downloading process, it is also necessary to determine the usage status of the user and determine the interruption of the hibernation record. Specifically, if the user operates the device during the downloading process, the downloading is interrupted, and the downloading is restarted after the user operates the device. If the downloading time during downloading exceeds the preset downloading duration, an interruption (the interruption time is preferably 30s) is started, and the downloading is started after the dormancy is finished. And in the downloading process, the size of the downloaded file needs to be detected in real time, if the downloaded file reaches the preset step size, the dormancy is started, and the process is circulated again until the downloading of the new firmware version is finished. Specifically, as shown in fig. 5, during downloading, if there is a user operating the device, the downloading is interrupted, the interrupt flag is set to 1, the downloading is started after the user operation is completed, after the downloading is started again, the 1 st time is counted again, the downloading step size is set to 1M, the duration is set to 30 seconds, the interrupt flag is set to 0, and then the downloading is circulated. In the downloading process, if the downloading data of the fixed downloading step length data is not completed within the fixed duration, the downloading is interrupted, the interruption identifier is set to be 1, the downloading is started after the user operation is completed, after the downloading is restarted, the 1 st time is counted again, the downloading step length is set to be 1M, the duration is set to be 30 seconds, the interruption identifier is set to be 0, and then the cyclic downloading is started.
