Specifically, the embodiment of the invention sends a download request of the version.txt file to the http server by using the curl through the http server address configured at the OLT end so as to read the content of the version.txt file. If the http server responds successfully, the ONU receives a version. And if the response of the http server fails, the ONU enters a sleep period, and continues to send an upgrading request to the http server after the sleep period elapses. In this process, the sleep period of the ONU may be any time, for example, if the sleep period is 1min, the ONU continues to send the upgrade request to the http server after 1 min.
And S230, if the current model of the ONU is consistent with the upgrading model in the upgrading version information and the current software version number of the ONU is inconsistent with the upgrading software version number in the upgrading version information, downloading the upgrading firmware information.

Optionally, the verification of the upgraded firmware information includes; calculating the MD5 value of the upgraded firmware information; if the MD5 value of the upgrade firmware information is the same as the check code of the upgrade firmware recorded by the upgrade version information, the check is correct.
Specifically, the MD5 value of the file is unique, and the verification of the MD5 value is used to ensure that the file is not modified during the transmission process. The embodiment of the application verifies that the firmware updating information firmware is transmitted correctly by checking the MD5 of the firmware updating information. And in addition, the firmware information firmware is written into the flash, and the ONU is restarted, so that the automatic upgrade of the ONU is completed.
Optionally, if any one of the following conditions is met, performing a sleep period of a preset time: the current model of the ONU is inconsistent with the upgrading model in the upgrading version information; the current software version number of the ONU is consistent with the upgrading software version number in the upgrading version information; and the update firmware information is checked to be wrong.
If the current model of the ONU is inconsistent with the upgrading model in the upgrading version information, indicating that the received version.txt sent by the http server does not belong to the same model as the current ONU; the current software version number of the ONU is consistent with the upgrading software version number in the upgrading version information, which indicates that the current ONU is the latest software version and does not need to be upgraded; and the update firmware information is checked to be wrong, which indicates that the firmware. Therefore, when any of the above situations occurs, the sleep period is required to be entered, and the upgrade request is sent to the http server again. In one embodiment, the setting of the sleep period may be the same or different after any of the above situations occur. For example, when the current model of the ONU is inconsistent with the upgrade model in the upgrade version information; or when the current software version number of the ONU is consistent with the upgrade software version number in the upgrade version information, the preset time can be set to be 1 minute, so that the sleep period is 1 minute; when the update firmware information is checked incorrectly, the preset time may be set to 1 hour, and thus the sleep period is 1 hour.
The embodiment of the invention sends the upgrading request to the http server, matches the files sent by the http server, and performs different operations under different matching results, thereby automatically completing the upgrading operation of the ONU equipment.
