It is a kind of flow chart of the method for upgrading software preferred embodiment of code reading card of the invention shown in reference picture 1.
In this embodiment, the method for upgrading software of the code reading card includes：
Step S10, code reading card is connected with usb host, movable memory equipment occurs on the usb host, wherein, it is described
Usb host is set up with code reading card by USB data line and is connected.
If code reading card has new software to need renewal, user can first get upgrading software kit, and be downloaded
Into equipment with USB host functions such as PC, flat board, notebooks.Therefore, software upgrade package can be downloaded to one by user
Platform be equipped with win7 PC, then code reading card is connected to by USB data line on PC USB port, PC will occur one can
Movable storage device.Certainly, user can also be completed by the PC of other different operating systems.
Step S20, user copies to software to be upgraded in movable memory equipment, with MSC classes (mass storage
Device class, mass storage device class) host-host protocol carry out data transmission.
Step S30, after code reading card is re-powered, the file downloaded in data memory area is upgraded, and can be fixed and be treated
The title of firmware updating, the file of correspondence title is retrieved according to above-mentioned title in the memory block, therefore, and user is replicating
, it is necessary to by it with correct name nominating when file to be upgraded is into the movable memory equipment.Shown in reference picture 2, the step
Suddenly following refinement step can be included：
Step S31, when reading firmware from the data storage area, verifies to the firmware, judges the correct of file
Property.
A kind of mode for verifying firmware accuracy is present embodiments provided, the firmware file includes the firmware content of itself
And CRC16 check codes.When generating the firmware, firmware content is verified using CRC16, increased at the end of firmware content
2 bytes are used to deposit CRC16 check codes.By carrying out CRC16 calculating, the verification with the firmware to described firmware content
Whether code multilevel iudge is consistent.
Step S32, if the firmware verify normal solution, judge the firmware version whether with currently used version one
Cause.
Step S33, software liter is carried out if the firmware version and currently used version are inconsistent using the firmware
Level.
When code reading card reads firmware out of described data storage area, the version number of the corresponding software of the firmware is obtained；
The version number of software by the version number got with being currently installed on is contrasted, to judge the software upgrade package correspondence
Software version it is whether consistent with being currently installed on version.
Present embodiments provide a kind of version for judging the firmware whether the mode consistent with being currently installed on version, pass through
Contrast version number to realize, existing software version number typically uses following form：Vxx.xx fixes 6 bytes, passes through character
More just can determine whether for string is consistent.
Whether due to simply unanimously limiting firmware version, firmware is can to support to retract legacy version.
A kind of method for upgrading software of code reading card proposed by the present invention, code reading card is connected by USB data line with usb host
Afterwards, movable memory equipment occurs at usb host end, upgrading software is copied in movable memory equipment, read by user
After code card is re-powered, software upgrading, method and system of the invention, without extra tool software, and to behaviour are automatically performed
Make system platform without rigors, it is only necessary to which usb host supports mass-memory unit, you can quickly and easily realize to reading code
The software of card is upgraded.

Data are read in reservoir.
Software upgrade module 30, after code reading card is re-powered, the file downloaded in data memory area is upgraded, can be with
The title of fixed firmware to be upgraded, the file of correspondence title, therefore, user are retrieved according to above-mentioned title in the memory block
When replicating file to be upgraded into the movable memory equipment, it is necessary to by it with correct name nominating.The institute of reference picture 4
Show, Software upgrade module 30 can include following refinement unit：
File verification unit 31, when reading firmware from the data storage area, verifies to the firmware, judges file
Correctness.
A kind of mode for verifying firmware accuracy is present embodiments provided, the firmware file includes the firmware content of itself
And CRC16 check codes.When generating the firmware, firmware content is verified using CRC16, increased at the end of firmware content
2 bytes are used to deposit CRC16 check codes.By carrying out CRC16 calculating, the verification with the firmware to described firmware content
Whether code multilevel iudge is consistent.
Version judging unit 32, during for reading firmware from the data storage area, judges the version of the firmware
It is whether consistent with currently used version.
Software upgrading unit 33, if correct for firmware verification, and if the firmware version and currently used version
This is inconsistent then using firmware progress firmware upgrade.
When code reading card reads firmware out of described data storage area, it is corresponding that version judging unit 32 obtains the firmware
The version number of software；The version number of software by the version number got with being currently installed on is contrasted, described to judge
Whether the corresponding software version of software upgrade package is consistent with being currently installed on version.
Present embodiments provide a kind of version for judging the firmware whether the mode consistent with being currently installed on version, pass through
Contrast version number to realize, existing software version number typically uses following form：Vxx.xx fixes 6 bytes, passes through character
More just can determine whether for string is consistent.
Whether due to simply unanimously limiting firmware version, firmware is can to support to retract legacy version.
Further, the software update system of the code reading card also includes with lower module：
Exception processing module 40, if that firmware is verified from the data storage area is incorrect for code reading card, or, upgrading
Made a mistake in journey, it is impossible to complete escalation process, exception processing module can send prompt message to inform that user software upgrades
Failure, if for example, code reading card is provided with alarm device, alarm can be sent, or, when being connected with display device on code reading card
When, exception processing module can also prompt message on the display apparatus.
