Embodiment Construction
[0017] see figure 1 , is a functional diagram of an electronic device upgrading system 100 in a preferred embodiment. The electronic device upgrade system 100 can be applied to electronic devices that need to be upgraded, and can read the upgrade program from an external storage medium (such as a disc, U disk, etc.) independent of the electronic device, and verify that the upgrade program is consistent with the original upgrade program Then upgrade the electronic device, thereby avoiding the upgrade error caused by data loss when the electronic device reads the upgrade program from the external storage medium. The electronic device upgrading system 100 includes an input unit 110 , a reading unit 120 , a storage unit 130 , a verification value generating unit 140 , a comparing unit 150 , an upgrading unit 160 , a prompt unit 170 and a display unit 180 . In this embodiment, the external storage medium is a disc 200 .
[0018] The input unit 110 is used for sending an instructi...

The invention discloses an upgrade system for an electronic device. The upgrade system for the electronic device comprises a reading unit, a storage unit, a verification value generation unit, a comparison unit and an upgrade unit, wherein the reading unit is used for reading an upgrade program from an external memory medium and a first verification value obtained by calculating according to the upgrade program in the memory medium, and storing the upgrade program in the storage unit; the verification value generation unit is used for calculating a second verification value according to the upgrade program stored in the storage unit; the comparison unit is used for comparing whether the second verification value is matched with the first verification value; the upgrade unit is used for executing an upgrade operation when the second verification value is matched with the first verification value. The invention further discloses an upgrade method for the electronic device.
Description
technical field [0001] The invention relates to an electronic equipment upgrading system and method, in particular to an electronic equipment upgrading system and method for preventing electronic equipment upgrading errors. Background technique [0002] In the current production process, electronic device software is often upgraded by using an upgrade program stored in a storage medium (such as a disc, a USB flash drive, etc.). However, during the upgrade process, due to hardware defects of the electronic device or unstable external voltage, the upgrade program read by the electronic device is likely to be inconsistent with the upgrade program stored in the storage medium, thus causing the upgrade of the electronic device to fail or After the upgrade, there are situations such as failure to turn on the computer, which makes the electronic equipment unable to work normally. Contents of the invention [0003] In view of this, it is necessary to provide an electronic device ...
