A kind of computer-readable recording medium, is stored thereon with computer program, and the computer program is held by processor
Row chip rewrites the data updating method of equipment.
Compared with prior art, the beneficial effects of the present invention are：
The present invention provides the data updating method that chip rewrites equipment, including the connection inspection of step power-up initializing, host computer
Survey, parse data, condition adjudgement, upgrading judges, upgrade file is decrypted, data renewal；The invention further relates to electronic equipment with can
Storage medium is read, the data updating method of equipment is rewritten for performing chip.The present invention by chip rewrite equipment in program with
Data separate, and rewrite the program in equipment to chip using DLL and carry out separating upgrading renewal with data.Data of the present invention
Upgrade method is flexible and changeable, saves upgrade cost, lowers upgrading difficulty, while this upgrade method operation is simple, realizes that chip changes
The flexible renewal upgrading of write device.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention,
And can be practiced according to the content of specification, below with presently preferred embodiments of the present invention and coordinate accompanying drawing describe in detail as after.
The embodiment of the present invention is shown in detail by following examples and its accompanying drawing.
Brief description of the drawings
Accompanying drawing described herein is used for providing a further understanding of the present invention, forms the part of the application, this hair
Bright schematic description and description is used to explain the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings：
Fig. 1 is that the chip of the present invention rewrites the data updating method flow chart of equipment；
Fig. 2 is the data updating method flow chart of the chip rewriting equipment in one embodiment of the invention；
Fig. 3 is that prior art device data upgrade schematic diagram；
Fig. 4 is that the data in the implementation of the present invention upgrade schematic diagram.
Embodiment
Below, with reference to accompanying drawing and embodiment, the present invention is described further, it is necessary to which explanation is, not
Under the premise of afoul, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination
Example.
Chip rewrites the data updating method of equipment, as shown in figure 1, comprising the following steps：
Power-up initializing, chip rewrite device power, and initialization chip rewrites the memory space and expansion interface of equipment, will
File mount rewrites the file system of equipment to chip in the memory space；
Whether host computer connecting detection, detection host computer are connected with expansion interface；
Data are parsed, chip rewrites equipment and the packet of expansion interface is parsed；Specifically use usb protocol stack pair
Packet is parsed；
Condition adjudgement, monitor chip and rewrite equipment state, judge that chip rewrites whether equipment state allows data to upgrade；
Upgrading judges, judges that chip is rewritten in the file system of equipment and whether there is upgrade file；Specifically, scanning chip
Rewrite and whether there is upgrade file under the root of the file system of equipment, in general, by detecting the version number of upgrade file,
As version number is higher than existing file version, then judge upgrade file be present；
Upgrade file is decrypted, and obtains described upgrade file, and described upgrade file is decrypted to obtain upgrading data；
Data update, and described upgrading data are updated into chip by DLL rewrites in equipment.
In one embodiment, memory space includes internal storage medium and outside expansion storage medium；Outside extension storage
Medium is specially SD card or TF card or USB flash disk or mobile hard disk, and expansion interface is specially USB.As shown in Fig. 2 electricity is initial in step
Change is specially：SD card is initialized, is delayed and waits SD card to load, SD card mistake is prompted as SD card does not load correctly, as SD card is read
Block the file system that SD card carry to chip is successfully then rewritten to equipment；USB is initialized, and enumerates configuration USB MASS
STORAGE, specifically, host computer is PC ends, whether detection PC ends connect through USB with chip rewriting equipment is connected.
As shown in figure 4, DLL is specially IAP interfaces, the data that chip is rewritten in equipment are broadly divided into three kinds, bottom
Program, application program and mandate accounting file；Wherein underlying programs are Default Value, and equipment can not be changed after coming into operation,
Application program and mandate accounting file user carry out upgrading renewal by USB in end.
In one embodiment, as shown in Fig. 2 step condition adjudgement is specially：Judge whether host computer file reception is completed,
It is to jump to judge whether host computer connection disengages, otherwise return is received not completing to identify and wait and finished receiving；In judgement
Whether position machine connection disengages, and is, returns to connection disengagement and identifies and wait reconnect, otherwise jumps to step upgrading and judges.
In one embodiment, also include data check before the renewal of step data, upgrading data are verified, if ascending series
The renewal of step data is then jumped to according to by examining, the returned data error message if upgrading data are not by examining.Specifically,
Specifically upgrade file is decrypted using AES for the decryption of step upgrade file, and step data check specifically uses CRC check.Example
Such as, authorize accounting file that operation will be encrypted before dispatching from the factory, in general is using aes algorithm with CRC algorithm to authorizing accounting file
It is encrypted, is converted into ciphertext form and sends to terminal client；When equipment of chip rewriting reads mandate accounting file, first to awarding
Weigh accounting file and carry out AES decryption, after decryption data are carried out with CRC check again, verification is carried out after passing through to mandate accounting file
Upgrading.
