The following detailed description of the implementation of the present invention is made with reference to specific embodiments:
fig. 1 shows an implementation flow of a firmware booting method of a banknote validator provided by an embodiment of the invention, which is detailed as follows:
in step S101, upon the start of the banknote validator, the backup firmware files in the firmware backup file directory are acquired.
Specifically, the Nand-flash memory has the advantages of large capacity, high rewriting speed and the like, and is suitable for storing a large amount of data.
In the embodiment of the invention, a Nand-flash memory is arranged in the currency detector, a firmware backup file directory is stored in the Nand-flash memory, a backup file of an original firmware file, namely a backup firmware file, is stored under the firmware backup file directory, and when a user starts the currency detector, a firmware guiding device acquires the backup firmware file in the firmware backup file directory.
Further, the step S101 is specifically: when the currency detector is started, the backup firmware files with the preset number in the firmware backup file directory are obtained.
The preset number of backup firmware files is specifically determined according to the number of the firmware required by the currency detector, and if the number of the firmware used by the currency detector is 5, the number of the corresponding backup firmware files is 5; if the number of firmware used by the bill validator is 3, the number of corresponding backup firmware files is 3.
Further, in order to avoid the problem that the banknote checking machine cannot be normally started due to the loss of the backup firmware file caused by other reasons, before step S101, a specific implementation process for determining whether the backup firmware file exists in the firmware backup file directory as shown in fig. 2 is further included.
In step S201, it is determined whether a backup firmware file exists in the firmware backup file directory.
In the embodiment of the present invention, whether a backup firmware file exists in the firmware backup file directory may be determined by a keyword or a file management list, where the keyword includes a name of an original firmware file.
Specifically, whether a file name in the firmware backup file directory contains a file of the keyword is detected according to the keyword, and if so, the file containing the keyword is determined to be a backup firmware file.
Optionally, the file names in the firmware backup file directory are extracted, the file names are compared with the file names of the corresponding directories in the file management list one by one, whether a file named as a backup firmware file in the file management list exists in the firmware backup file directory is determined, and if the file exists, it is determined that the backup firmware file exists in the firmware backup file directory.
Further, the step S201 specifically includes: and determining whether a preset number of backup firmware files exist in the firmware backup file directory, for example, determining whether 5 backup firmware files exist in the firmware backup file directory.
In step S202, if the firmware backup file directory does not have the backup firmware file, the firmware package of the preset version is searched from the preset directory of the banknote checking machine according to the preset priority.
In the embodiment of the invention, the file system used in the currency detector is a linux file system, the memory is a Nand-flash memory, wherein a plurality of file directories such as a firmware backup file directory, a firmware upgrade file directory, a factory backup file directory, a working file directory and the like are stored in the Nand-flash memory, wherein the firmware backup file directory, the firmware upgrade file directory and the working file directory are readable and writable file directories, and the factory backup file directory is a read-only file directory.
The factory backup file directory is set as a read-only file directory, so that the original firmware file stored in the factory backup file directory can be prevented from being damaged, the factory backup file directory can be used for multiple times, and the safety and the recoverability of the firmware file of the currency detector are guaranteed.
Specifically, the firmware backup file directory stores backup firmware files generated according to original firmware files or upgraded firmware files.
The firmware upgrade file directory stores upgrade firmware packages of different versions upgraded based on the original firmware file.
The factory backup file directory stores original firmware packages of original versions.
Here, the preset directories include a firmware upgrade file directory and a factory backup file directory; the firmware packages with the preset versions are specifically upgrade firmware packages with different versions and original firmware packages with original versions.
Here, the preset priority is set to preferentially traverse and search the upgrade firmware package in the firmware upgrade file directory, and then traverse and search the original firmware package of the original version in the factory backup file directory, if the required upgrade firmware package is searched in the firmware upgrade file directory, the original firmware package of the original version does not need to be searched in the factory backup file directory, otherwise, the original firmware package of the original version needs to be searched in the factory backup file directory.
Further, the step S202 is specifically: and if the firmware backup file directory does not have the backup firmware files with the preset number, searching a firmware package with a preset version from a preset directory of the currency detector according to the preset priority.
Here, when the firmware of the banknote validator is upgraded, if a part of the backup firmware files in the firmware backup file directory may be lost due to human misoperation or a defect of the program itself, it is determined that a preset number of backup firmware files do not exist in the firmware backup file directory, for example, 5 firmware files are used in the banknote validator, and correspondingly, the number of the backup firmware files in the firmware backup file directory should also be 5, and when the number of the backup firmware files is less than 5, it is determined that the backup firmware files do not exist in the firmware backup file directory. At this time, the firmware guiding device searches the upgrade firmware package of the latest version from the firmware upgrade file directory, and if the upgrade firmware package of the latest version or the upgrade firmware package of other versions cannot be searched in the firmware upgrade file directory, the original firmware package of the original version is searched in the factory backup file directory; when the original firmware package of the original version cannot be found in the factory backup file directory, a prompt message is sent to report an error, such as a program error, a corresponding firmware package cannot be found, and the like, wherein the prompt message may be displayed at a screen end or prompted by voice.
In step S203, the found firmware package of the preset version is decompressed to generate a corresponding backup firmware file, and the corresponding backup firmware file is loaded into the firmware backup file directory.
In the embodiment of the present invention, in order to ensure that the firmware backup file directory stores backup firmware files, and avoid the situation that files are lost or damaged due to directly using the firmware packages in the upgrade firmware directory and the factory firmware backup file directory, when a firmware package of a preset version is found from the preset directory, for example, when an upgrade firmware package of a latest version or an original firmware package of an original version is found, the firmware package of the preset version is decompressed to generate corresponding backup firmware files, and the decompressed backup firmware files are loaded into the firmware backup file directory.
Further, step S203 specifically includes: and decompressing the found firmware packages of the preset versions to generate backup firmware files corresponding to the preset number, and loading the backup firmware files of the preset number into the firmware backup file directory.
For example, when the number of the firmware used by the banknote validator is 5, the found firmware package of the preset version is decompressed to generate corresponding 5 backup firmware files, and the 5 backup firmware files are loaded into the firmware backup file directory.
Further, in order to avoid that the banknote validator cannot be normally started due to the backup firmware file being damaged, a specific flow for checking whether the backup firmware file is damaged is also included before step S101, as shown in fig. 3.
In step S301, it is checked whether the backup firmware file is corrupted through the file management list.
In the embodiment of the present invention, the file management list records file data in all directory files, such as file names, file sizes, file addresses, and the like, where the file address is a directory to which the file belongs, and the file address can be used to know which file directory the file is stored in.
Specifically, the name, the file size, and the check value of the backup firmware file are recorded in the file management list in step S301, and step S301 is implemented by a specific flow as shown in fig. 4.
In step S401, the actual file size of the backup firmware file is acquired.
In the embodiment of the present invention, if a file is lost or corrupted, the actual file size of the file may change, for example, the file size of the correctly used backup firmware file is 20M, and when part of the file data in the backup firmware file is lost or corrupted, the actual file size of the backup firmware file may be greater than or less than 20M.
Further, step S401 specifically includes: and respectively acquiring the actual file sizes of the backup firmware files of the preset number.
In step S402, it is determined whether the actual file size matches the corresponding file size recorded in the file management list, based on the name of the backup firmware file.
In the embodiment of the present invention, after the actual file size of the backup firmware file is obtained, the actual file size is compared with the file sizes with the same file name recorded in the file management list to determine whether the sizes of the two files are consistent.
Further, in step S402, it is specifically determined whether the actual file sizes of the preset number of backup firmware files are consistent with the corresponding file sizes recorded in the file management list according to the names of the backup firmware files.
In step S403, if the actual file size matches the corresponding file size recorded in the file management list, it is determined whether the backup firmware file is corrupted by the check value in the file management list.
In the embodiment of the present invention, if the actual file size of the backup firmware file is consistent with the corresponding file size recorded in the file management list, it is necessary to determine whether the backup firmware file is damaged or not through the check value recorded in the file management list.
And when the check value in the backup firmware file is consistent with the check value recorded in the file management list, judging that the backup firmware file is not damaged and has file integrity.
And when the check value in the backup firmware file is inconsistent with the check value recorded in the file management list, judging that the backup firmware file is damaged and has no file integrity.
Further, if the actual file size is not consistent with the corresponding file size recorded in the file management list, it is determined that the backup firmware file is damaged and has no file integrity.
Further, the step S403 is specifically: if the actual file size of the backup firmware files in the preset number is consistent with the corresponding file size recorded in the file management list, respectively determining whether the backup firmware files in the preset number are damaged or not according to the check values in the file management list, and when any one backup firmware file in the backup firmware files in the preset number is damaged, judging that the backup firmware files in the preset number are damaged.
Further, the step S301 is specifically: and checking whether the preset number of backup firmware files are damaged or not through the file management list.
For example, when the number of the firmware used by the bill validator is 5, the file management list is used to check whether the 5 backup files stored in the Nand-flash memory are damaged or not, and the integrity is not provided.
In step S302, if the backup firmware file is damaged, the damaged backup firmware file is deleted, and a firmware package with a preset version is searched from a preset directory of the banknote validator according to a preset priority.
In the embodiment of the invention, in order to avoid the situation that the banknote checking machine cannot be normally started due to interference or wrong use caused by the damaged backup file in the Nand-flash memory, after the backup firmware file is determined to be damaged, the damaged backup firmware file is deleted, and the firmware package of the preset version is searched from the preset directory stored in the Nand-flash memory in the banknote checking machine according to the preset priority.
Further, the step S302 specifically includes: if the backup firmware files of which the number is less than or equal to the preset number are damaged in the backup firmware files of the preset number stored in the firmware backup file directory, deleting all the backup firmware files of the preset number, and searching the firmware package of the preset version from the preset directory of the currency detector according to the preset priority.
In step S303, the found firmware package of the preset version is decompressed to generate a corresponding backup firmware file, and the corresponding backup firmware file is loaded into the firmware backup file directory.
Further, the step S303 is specifically: and decompressing the found firmware packages of the preset versions to generate backup firmware files corresponding to the preset number, and loading the backup firmware files of the preset number into the firmware backup file directory.
In the embodiment of the invention, whether the backup firmware file in the firmware backup file directory is damaged is checked, and if the backup firmware file is damaged, the backup firmware file generated according to the firmware package of the preset version is reloaded, so that the working firmware file is ensured to be correct and complete when the currency detector is started, the currency detector can be ensured to be started normally, and the safety and the recoverability of the boot firmware are ensured.
In step S102, the corresponding mapping firmware file generated according to the backup firmware file is loaded into the working file directory.
In the embodiment of the present invention, the backup firmware files and the mapping firmware files correspond to each other one to one, that is, the contents of the backup firmware files and the contents of the mapping firmware files are consistent and are only stored in different file directories with different names respectively.
Specifically, a specific flow of loading the mapping firmware file into the working file directory in step S102 is shown in fig. 5.
In step S501, a corresponding mapping firmware file is generated from the backup firmware file.
In the embodiment of the invention, after the backup firmware file is determined not to be damaged, the corresponding mapping firmware file is generated according to the backup firmware file.
Specifically, the step S501 specifically includes: and generating a corresponding preset number of mapping firmware files according to the preset number of backup firmware files, for example, if there are 5 backup firmware files, generating 5 mapping firmware files correspondingly.
In step S502, the original mapped firmware file in the working file directory is deleted.
In the embodiment of the invention, in order to improve the starting efficiency of the currency detector and ensure the starting stability of the currency detector, when the currency detector is started, if the original mapping firmware file is detected to be stored in the working file directory, the original firmware file is deleted so as to reload the correct mapping firmware file.
Further, step S502 specifically includes: and deleting a preset number of original mapping firmware files in the working file directory.
