Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The invention aims at the upgrading scene that: the device to be upgraded can only download the upgrade package but can not install the upgrade package during the execution of the main function program, can not achieve the purpose of applying the upgrade package by restarting software, can only install the upgrade package when restarting the device, and then starts the main function program.
Fig. 1 is a schematic diagram of the main steps of a method of software upgrade according to an embodiment of the present invention. The method of software upgrade of the present invention is performed by a separate, dedicated upgrade tool, rather than by the main function program, and the upgrade tool is self-starting at device start-up. As shown in fig. 1, the method for upgrading software according to the embodiment of the present invention mainly includes the following steps S101 to S103.
Step S101: when the equipment is started, whether an upgrade package is stored in a local nonvolatile memory of the equipment is searched;
step S102: if yes, upgrading the software according to the upgrade package;
step S103: otherwise, starting the software upgrading check process until a new upgrading package is checked, downloading the new upgrading package from the server and storing the new upgrading package in a local nonvolatile memory of the equipment, and then informing the user to restart the equipment to complete the software upgrading.
According to the technical scheme of the invention, the upgrade package is stored on a local nonvolatile memory of the equipment. A non-volatile memory NVM (non-volatile memory) refers to a computer memory that does not lose stored data when the current is turned off, for example: hard disk or flash memory, etc. Therefore, after the equipment is restarted, the upgrading package downloaded before the equipment is restarted can be still stored in the equipment.
According to the embodiment of the invention, software upgrading is performed through an independent and special upgrading tool Updatertool, and an upgrading program is not deployed in a main function program of the software, so that equipment to be upgraded and the software to be upgraded for implementing upgrading can be accurately controlled. Updatertool is a software upgrade tool that can perform software upgrades according to set logic. There are two ways of initiating UpdaterTool: parameters related to upgrading can be configured in a mode of starting with parameters (such as passwords), and an upgrading mode can be entered in a mode of starting without parameters (self-starting). Software upgrade configuration can be performed by starting the upgrade tool in a parameterized manner. For example: the relevant information of the file server, the relevant information of the software to be upgraded, the relevant information of the equipment to be upgraded and the like can be configured.
According to an embodiment of the present invention, the software upgrading according to the upgrade package specifically includes: and calculating a check code corresponding to the file in the upgrade package, comparing the check code with a preset check code, and installing the upgrade package to upgrade the software when the check code is consistent with the preset check code. Therefore, the validity of the upgrade package can be judged by checking the files in the upgrade package. And only after the upgrade package passes the verification, the upgrade package can be installed. Generally, the upgrade package is compressed, and therefore, the upgrade package needs to be decompressed before being verified. The upgrade package may include contents such as an upgrade program, a check code generated by the system, and an upgrade history, and when calculating the check code corresponding to the file in the upgrade package, the check code corresponding to the upgrade program is generally calculated. And then, comparing the check code obtained by calculation with the check code generated by the system and included in the upgrade package to judge whether the file in the upgrade package is correct, complete and effective. In calculating the check code corresponding to the ascending order of the upgrade, a common hashing or encryption algorithm may be used, for example: MD5(MD5Message-Digest Algorithm, 5 th edition), CRC (Cyclic Redundancy Check) or MD2, MD3, etc. In addition, according to another embodiment of the present invention, only the upgrade program may be included in the upgrade package, and then a file for recording the check code is downloaded from the file server, and then the calculated check code is compared with the check code on the downloaded file for recording the check code to determine the validity of the upgrade package.
According to an embodiment of the present invention, after the software upgrade is performed according to the upgrade package, it is also possible to: deleting all upgrade packages stored on the equipment; and updating the version number of the upgraded software on the device. Therefore, when the upgrading packet is found on the equipment, the upgrading packet is determined to be the upgrading packet to be upgraded without judging whether the upgrading packet is the latest upgrading packet or not, so that the judging operation of the upgrading packet is simplified; in addition, the version number of the upgraded software is updated, namely the version number of the software can be compared with the corresponding version number in the upgrade package to determine whether the upgrade is needed, so that the upgrade judgment process is further simplified.
According to another embodiment of the present invention, before starting the software upgrade checking process, the method further includes: a current version number of software on the device is obtained.
According to another embodiment of the present invention, before the software upgrade checking process is started, the main function program of the device may also be started; moreover, when notifying the user to restart the device to complete the software upgrade, the method may specifically include: and informing the main function program in an interprocess communication mode, and informing a user of equipment restart by the main function program so as to complete software upgrading. Because the main function program is displayed on the full screen on the user interface, the upgrading tool informs the main function program, and the main function program informs the user of restarting the equipment, so that the user can be better informed on the user interface. In addition, in the specific implementation process, the upgrade tool may also use other notification methods, such as: short message, mail, buzzer, etc. to inform the user to restart the device. In addition, when the user restarts the device, the user can flexibly select the restart time according to the use condition, for example, the user can select the device to restart when the device is in a non-working state or a standby state.
According to an embodiment of the present invention, the software upgrade checking process may specifically include:
acquiring the identifier of the equipment which does not need to be upgraded from the server;
if the identifier is not acquired or the acquired identifier does not include the identifier of the equipment, acquiring the highest version number of the upgrade package of the software on the equipment from the server, and judging whether the highest version number is higher than the current version number of the software on the equipment or not;
and if the version number is higher than the preset version number, taking the upgrade package with the highest version number as a new upgrade package.
According to another embodiment of the present invention, the identifier of the device includes grouping information to which the device belongs; moreover, the obtaining of the highest version number of the upgrade package of the software on the device from the server may specifically include:
acquiring an upgrade package list from a server;
searching an upgrade package which contains grouping information of the equipment in the name and an upgrade package which does not contain a grouping field from an upgrade package list;
and obtaining the version number of the upgrade package according to the searched name of the upgrade package to determine the highest version number.
The following describes the implementation of the present invention with reference to specific embodiments.
According to the embodiment of the invention, the following scenario settings can be made:
1. assuming that the ID of the device is GroupNM _ IDx, wherein the GroupNM field identifies the name of the group to which the device belongs, and IDx is the index value of the device in the group to which the device belongs;
2. assuming that the software upgradeable to the device is SoftWareA, SoftWareB and SoftWareC (the specific number may be arbitrary), the version number of each software may be set to a format of X or x.y or x.y.z, where X, Y and Z are a major version number, a minor version number and a revision version number, respectively. For example, if the version number of a piece of software is 2.3.5, the major version number is 2, the minor version number is 3, and the revision version number is 5. The major version number can be changed only when the important function is changed, the minor version number corresponds to the minor function upgrade, and the revision version number can be updated when the software is upgraded every time;
3. the File Server is, for example, an FTP Server (File Transfer Protocol Server, which is a computer providing File storage and access services on the internet and provides services according to the FTP Protocol), the device has the right to read, list and access subdirectory for the FTP File directory of the File Server, and the maintainer has all the right to operate files and folders for the FTP File directory of the File Server. The list directory means that the client can require the server to return all file lists under one folder; the entry of the subdirectories means that the client can access all levels of directories in the file server;
4. the executable program for implementing the software upgrade function of the device is Updatertool. In an embodiment of the present invention, the updatetool is a software upgrading tool, and software upgrading can be performed according to the set logic. There are two ways of initiating UpdaterTool: parameters related to upgrading can be configured in a mode of starting with parameters (such as passwords), and an upgrading mode can be entered in a mode of starting without parameters.
Before the software upgrade is performed, the following preparation operations are also required to be performed:
1. the parameters related to the upgrade are initially set or the previously set parameters are modified:
the Updatertool is manually activated with a parameter (the parameter may be a specific string that is a maintenance password), and the program enters the parameter configuration mode after activation. In the parameter configuration mode, a configurator may input parameters related to the upgrade, such as an IP (internet protocol) address of the file server, a user name and a password of the file server, a current version number of softward a, a current version number of softward b, a current version number of softward c, and an identification id (identity) of the device to be upgraded, at the prompt of a program (a prompt may be presented with a user interface or a command line), and after confirming the input, the configurator stores the parameters in a nonvolatile memory (a hard disk, a flash memory, or the like) of the device to be upgraded. If software such as SoftWareA, SoftWareB, SoftWareC and the like does not exist in the current device to be upgraded, the version number of the device to be upgraded can be set to 0 or 0.0 or 0.0.0 when the initial parameters are set;
2. preparing an upgrade package:
taking softwave a as an example, assuming a form named "x.y.z" of the version number, the corresponding upgrade package name is softwave a-group nm-x.y.z-yyyymmdd.bin, where yyyyymmdd is year, month and day information when the upgrade package is made, which is not necessary, but the name of the upgrade package must include the software name and version number information of the upgrade package. The upgrade package is generally a compressed package, which is compressed from the following three files (folders): SoftWareA's upgrade program, md5.txt (file content is SoftWareA's MD5 code), and update. log (content is SoftWareA's upgrade history). If SoftWareA is a plurality of files or a folder, it(s) is (are) compressed into a compressed file, and then the MD5 code of the compressed file is written into md5. txt. Wherein, the GroupNM field in the upgrade package name is unnecessary, and if there is no GroupNM field, it indicates that all groups of devices can download and install the upgrade package. If the GroupNM field is carried, only the equipment belonging to the GroupNM group can download and install the upgrade package;
3. and putting the upgrade package into a corresponding file directory of the file server:
the file directory of the file server may be organized in such a way that: the root directory is put into an ID directory of a device that does not need to be upgraded, whose contents are separated by spaces. Three folders are created in the root directory under the names SoftWareA, SoftWareB and SoftWareC of the software to be upgraded, and then a new upgrade package (e.g., SoftWareA-GroupNM-x.y.z-yyyymmdd.bin) is put into the corresponding folder (e.g., SoftWareA). Txt is not necessary, and the role is to write the ID of the device that does not need to be upgraded into this file when the upgrade needs to be performed for a part of the device.
Through the preparation operation, equipment and software which need to be upgraded can be set, an upgrade package is prepared, and the upgrade package is stored in a corresponding file directory of the file server. And then, software upgrading can be carried out. The upgrade mode is entered by starting the UpdaterTool without a parameter, so that the UpdaterTool performs software upgrade according to the preset logic. Specifically, the "no parameter mode startup updatetool" needs to be put into the boot software auto-start sequence of the device. When the computer is started, some software can be started in a certain sequence, and the names of the software can be input in a script file in the linux to realize the software. Automatic startup of UpdaterTool at device startup is achieved by placing UpdaterTool as one of the items in this self-startup script.
Fig. 2 is a schematic flow chart of software upgrade according to an embodiment of the present invention. As shown in fig. 2, the software upgrading process according to the embodiment of the present invention mainly includes the following steps S1 to S7.
Step S1: when the equipment is started, searching whether an upgrade package exists in a folder for storing the upgrade package on a local nonvolatile memory of the equipment, and if the upgrade package does not exist, entering the step S2; and if the upgrade package exists, decompressing and verifying the upgrade package (MD5 code), and installing the upgrade package after normal decompression and verification are successful. Then all upgrade package files in the folder in which the upgrade package is stored are deleted, and the version number of the software that has just been upgraded before on the device is updated, and then the process proceeds to step S2. The operation sequence of deleting all upgrade package files after installing the upgrade package and updating the software version number can furthest avoid the influence caused by accidental power failure in the software upgrading process.
Step S2: the current version number of each software on the device is obtained from the non-volatile memory local to the device, and then the process proceeds to step S3.
Step S3: the main function program of the apparatus is started, the apparatus starts to operate, and then the process proceeds to step S4. Wherein each device has its own main function, such as: the main function program of an ATM (Automatic Teller Machine) Machine is a program related to depositing and withdrawing money. The main functions of a plurality of devices of the same type may be the same or different (e.g., different version numbers).
Step S4: and starting a software upgrading checking process, wherein the software upgrading checking process is a process of periodically checking whether the software of the equipment needs to be upgraded on the file server. When it is checked that there is a new upgrade package, the process proceeds to step S5. The software upgrade checking process may specifically include the following steps:
step S41: the file server is accessed, and whether the file (recording the identification of the device which does not need to be upgraded) exists or not is checked. If not, the process proceeds to step S42. Otherwise, downloading the file and checking whether the identifier ID of the device is in the file, if so, indicating that the upgrade is not needed, and executing step S41 again after waiting for a certain time (a set check period), otherwise, entering step S42;
step S42: the files are respectively switched to upgrade package storage directories corresponding to 3 pieces of software, namely SoftWareA, SoftWareB and SoftWareC, of the file server, and an upgrade package directory LIST in each directory is acquired (if the file server is an FTP server, the file LIST can be acquired by sending a "LIST" command). And then, determining whether a new upgrade package of the software exists according to the upgrade package directory list corresponding to each software. Taking SoftWareA as an example, according to the name of the upgrade package in the upgrade package directory list corresponding to the software, the version number of the upgrade package of SoftWareA is obtained by analyzing the group information GroupNM including the device and the name of the upgrade package not including the GroupNM field, and the name of the upgrade package with the highest version number is determined. Comparing the highest version number with the current version number of the software SoftWareA installed on the device, and if the highest version number is higher than the current version number of the software SoftWareA installed on the device, taking the upgrade package of the highest version number as a new upgrade package, and proceeding to step S5; otherwise, step S41 is executed again after waiting for a certain time (the set check period). According to one embodiment of the invention, when comparing version numbers, the size of a main version number X is compared firstly, and the version number with larger X is higher; when X is the same, the larger version number of Y is higher; in the case where X and Y are both the same, the larger version number of Z is high.
Step S5: the device downloads the new upgrade package from the file server and stores the downloaded new upgrade package in a folder storing the upgrade package on a local non-volatile memory of the device. If the folder for locally storing the upgrade package has the upgrade package of an old version (the upgrade package is not decompressed and installed), the upgrade package of the old version is directly deleted, that is, at most one upgrade package of the same type is stored in the folder for storing the upgrade package, so that the upgrade packages searched from the folder for storing the upgrade packages are all the upgrade packages of the latest version when the equipment is started each time. Then, the process proceeds to step S6.
Step S6: the update tool updatetool notifies the main function program of the device in an inter-process communication manner that a new update package has been downloaded, and the main function program notifies the user in a certain manner (e.g., through a user interface popup) that the device is restarted to complete the software update. Specifically, the user may select an appropriate time for the device to restart, for example: and restarting the equipment when the equipment is in a non-working state or a standby state. Then, the process proceeds to step S7.
Step S7: after waiting for a predetermined time (a set check period), the process proceeds to step S41.
Wherein, the steps S2 and S3 may be executed simultaneously, or the step S2 is executed first and then the step S3 is executed; the step S3 may be executed first and then the step S2 may be executed, which does not affect the implementation of the present invention.
In addition, when the method is specifically implemented, the equipment for implementing the upgrade is controlled in a mode of saving the identifier of the equipment which does not need to be upgraded into the configuration file and including the group name of the equipment to be upgraded in the name of the upgrade package; similarly, the device may also control the device to perform the upgrade by inquiring whether there is an upgrade instruction from the server, or by requesting the upgrade from the server according to the ID of the device itself, and replying whether the upgrade is possible or not from the server.
