[0006] S1 processes the packaged software to obtain a secondary compressed file;

[0007] S2 decompresses and verifies the secondary compressed file. If the decompression and verification succeed, the local file of the main program is replaced and the upgrade file is transmitted to the underlying driver through the communication protocol. If the decompression fails, the decompression and verification failure is outputted.

[0008] S3: The underlying driver is upgraded based on the upgrade file.

[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0038] See also Figures 1 to 8 The present invention provides a method for upgrading a blood system instrument, comprising the following steps:

[0039] S1 processes the packaged software to obtain a secondary compressed file;

[0040] S11 compresses the packaged software and generates a key for encryption to obtain a first-level compressed package;

[0041] Specifically, the packaging software first compresses the software package and generates a key (the key of the file calculated by the AES encryption rule) for automatic encryption to generate a first-level compressed package.

[0042] S111 obtains the original data, groups it, and sets the initial key and initialization vector;

[0043] Specifically, the original data is obtained and grouped; the original data is grouped into 128-bit groups; a 256-bit initial key and a 128-bit initialization vector (IV) are set.

[0044] S112 expands the initial key to generate multiple rounds of keys;

[0045] Specifically, for key expansion, the initial key is used to generate multiple rounds of keys through a key scheduling algorithm.

[0046] S113 performs operations based on the grouping and the multi-round keys to obtain a key.

[0047] Specifically, in the initial round, the initial group is XORed with the first round key; the main round operations are byte substitution, row shift, column confusion, and round key addition operations; repeated 13 times; the final round operation is byte substitution, row shift, and round key addition operations; the encrypted key is obtained. The secret key is obtained as output, and the obtained secret key is used to encrypt and compress the file to obtain an encrypted and compressed zip compressed file.

[0048] S12 calculates the md5 value of the first-level compressed package and saves it in the md5.txt file to obtain a verification file;

[0049] Specifically, after encryption is completed, the md5 value of the compressed package is calculated and saved in the md5.txt file as an integrity check code.

[0050] S13 packages the verification file and the first-level compressed package to obtain a second-level compressed file.

[0051] Specifically, the md5 value and the upgrade file are packaged together to generate a secondary compressed file for the upgrade.

[0052] S2 decompresses and verifies the secondary compressed file. If the decompression and verification succeed, the local file of the main program is replaced and the upgrade file is transmitted to the underlying driver through the communication protocol. If the decompression fails, the decompression and verification failure is outputted.

[0053] S21 decompresses the secondary compressed file, and if successful, obtains the primary file and the verification file; if the decompression fails, outputs a decompression failure prompt;

[0054] Specifically, upgrade the software in the upgrade interface and select the APP software upgrade interface. Open the local upgrade module and close the main program. Insert the USB flash drive into the instrument USB port, select the corresponding software path in the local upgrade module, and the software determines whether the upgrade file naming rules are met. After obtaining the software path, click Upgrade to start the upgrade process. First, decompress the upgrade file of the secondary compressed package to obtain the primary compressed package and the verification file.

[0055] S22 performs integrity verification on the primary file based on the verification file in the temporary folder;

[0056] Specifically, verify the file validity of the first-level compressed package in the temporary folder.

[0057] S23 completes the upgrade by replacing the main program locally based on the successfully verified primary file;

[0058] Specifically, the key of the file is calculated according to the AES encryption rule, and the first-level file is decrypted. The upgrade file in the temporary folder is overwritten to the main program directory to upgrade the main program.

[0059] S24 decrypts the primary file based on the key to generate an upgrade file, and transmits the upgrade file to the underlying driver using a communication protocol.

[0060] The communication protocol is the CAN communication protocol.

[0061] Specifically, the upgrade file is transmitted to the underlying driver using the CAN protocol.

[0062] S3: The underlying driver is upgraded based on the upgrade file.

[0063] Specifically, when upgrading the underlying driver, you first need to obtain the file path in the USB flash drive. After obtaining the file path, decrypt the file and verify the file integrity. After verifying the file, execute the underlying driver upgrade process. First restart the underlying driver to ensure that the upper-layer software and the underlying driver enter the synchronous upgrade mode. Send the upgrade instruction to the corresponding underlying driver. Synchronize the file length with the underlying driver and receive the underlying reply. Read the upgrade file and split the upgrade file into fixed-size files and send them to the underlying driver in sequence. After the file is sent, perform an XOR check with the underlying layer. After the check is completed, wait for the instruction that the underlying upgrade is completed. After receiving the instruction, the upgrade is successful.

[0064] Beneficial Effects

[0065] 1. The driver file upgrade process has been changed from upgrading the bin file to first decompressing the zip file and then upgrading the bin file. A file damage identification process has been added to avoid the problem of upgrade failure caused by upgrading damaged bin files.

[0066] 2. Added file verification process and decryption process during decompression, which increased the difficulty of manual file modification and ensured the reliability of upgraded files.

[0067] 3. Add file integrity check based on md5 value to ensure that the program can be recognized after the upgrade file is modified.

[0068] 4. Automatically identify the upgrade programs of different modules, automatically determine the underlying driver and host software program, and solve the problem of upgrading the wrong module.

[0069] The above disclosure is only a preferred embodiment of a method for upgrading a blood system instrument of the present invention. Of course, it cannot be used to limit the scope of rights of the present invention.
