Various embodiments of the method of the present invention are presented in terms of the above-described hardware architecture.
Referring to fig. 2, in a first embodiment of the electric meter upgrading method of the present invention, the electric meter upgrading method includes the steps of:
step S10, receiving an upgrade package sent by a server, wherein the upgrade package comprises an initial address, a new function address list and an upgrade file corresponding to a module to be upgraded;
in this scheme, before leaving the factory, the software program inside the smart meter is pre-divided into a plurality of modules, for example, into a display module, a communication module, a metering module, a settlement module, and other functional modules. Each module comprises at least one function, a function address list is defined for each module in advance, the function address list comprises a starting address of the module and an offset address corresponding to each function in the module, and a complete address of one function is composed of the starting address of the module and the corresponding offset address. By accessing the function address list, the isolation between different modules can be realized, and the access between different modules is not influenced, for example, the module A needs to call the function a in the module B, the function address list of the module B is accessed, the complete address of the function in the module B is inquired, and then the function in the module B is accurately called according to the complete address.
The smart meter establishes a communication connection with the server to obtain an upgrade package of the smart meter, and it should be understood that the upgrade package may be a latest version of the electric energy meter software or an electric energy meter software version updated by a developer according to a user requirement, which is not specifically limited in this embodiment. The server encapsulates and packages the start address of the module to be upgraded, the new function address list of the module to be upgraded and the upgrade file of the module to be upgraded in the smart electric meter to form an upgrade package, wherein the upgrade package may include the start address, the new function address list and the upgrade file corresponding to one or more modules to be upgraded respectively. And when the server determines that some modules of the intelligent electric meter need to be upgraded, the server sends the upgrade package to the intelligent electric meter through the network.
Step S20, analyzing the upgrade package to obtain the initial address, function address list and upgrade file corresponding to the module to be upgraded;
step S30, upgrading the module to be upgraded according to the initial address and the upgrade file corresponding to the module to be upgraded;
step S40, the current function address list of the module to be upgraded is replaced by the new function address list corresponding to the module to be upgraded.
And after receiving the upgrade package, the intelligent electric meter analyzes the upgrade package to obtain an initial address, a new function address list and an upgrade file corresponding to at least one module to be upgraded. The intelligent electric meter can determine the position of the module to be upgraded in the whole program code through the initial address corresponding to the module to be upgraded, so that the installation path of the module to be upgraded is determined. And then updating the current program code of the module to be upgraded by using the program code in the upgrade file of the module to be upgraded according to the installation path of the module to be upgraded. The whole program code of the module to be upgraded is updated, so that the offset address of each function in the module to be upgraded may be changed, the new function address list of the module to be upgraded in the upgrade package is a new function address list which is established in advance according to the program code after the module to be upgraded is upgraded, and after the module to be upgraded is upgraded by adopting the upgrade file, the current function address list of the module to be upgraded is replaced by the new function address list in the upgrade package. Therefore, after the modules are upgraded, the mutual calling among the modules is not influenced.
The method comprises the steps that an upgrade package sent by a server is received, wherein the upgrade package comprises an initial address, a new function address list and an upgrade file corresponding to a module to be upgraded; analyzing the upgrade package to obtain an initial address, a function address list and an upgrade file corresponding to the module to be upgraded; upgrading the module to be upgraded according to the initial address and the upgrading file corresponding to the module to be upgraded; and replacing the current function address list of the module to be upgraded with the new function address list corresponding to the module to be upgraded. Therefore, the data packets of the corresponding modules are only required to be transmitted each time when new functions are added, the total quantity of the data packets transmitted in the upgrading process is reduced, the transmission time is shortened, only the codes of the corresponding modules need to be modified, the requirements can be met only by upgrading the code areas of the corresponding modules during upgrading, the upgrading speed is accelerated, and the upgrading efficiency is improved.
Further, according to the first embodiment of the electric meter upgrading method, the second embodiment of the electric meter upgrading method is provided, and in the embodiment, the upgrading package further comprises an upgrading check value corresponding to the module to be upgraded; the step S30 further includes:
step S50, after the upgrade is finished, calculating the verification value to be verified corresponding to the upgraded module to be upgraded;
step S60, judging whether the check value to be verified corresponding to the module to be upgraded is matched with the upgrade check value corresponding to the module to be upgraded;
step S61, when the verification value to be verified corresponding to the module to be upgraded is successfully matched with the upgrading verification value corresponding to the module to be upgraded, determining that the module to be upgraded is successfully upgraded;
step S62, when the matching between the verification value to be verified corresponding to the module to be upgraded and the upgrade verification value corresponding to the module to be upgraded fails, determining that the module to be upgraded fails to be upgraded.
In order to ensure whether the module to be upgraded is successfully upgraded, namely whether an error occurs in the upgrading process, the server also encapsulates an upgrading check value corresponding to the module to be upgraded in an upgrading packet for verifying whether the module to be upgraded is successfully upgraded, wherein the upgrading check value is an upgrading check value calculated by the server according to a program code after the module to be upgraded is successfully upgraded. After the upgrade is completed, a preset check value algorithm is adopted to calculate a to-be-verified check value corresponding to the upgraded module, the preset check value algorithm is a check value calculation algorithm adopted for verifying the integrity of the file in the prior art, and is not repeated herein, and then whether the to-be-verified check value is matched with the upgrade check value analyzed from the software package or not is judged, namely whether the to-be-verified check value is consistent with the upgrade check value analyzed from the software package or not is judged, and if the matching is successful, the upgrading of the module to be upgraded is determined to be successful. If the matching is not successful, that is, the matching is inconsistent, it is indicated that the program code of the module to be upgraded after the upgrading is different from the expected program code after the upgrading is successful, and the module to be upgraded is determined to be failed in upgrading.
It should be noted that the upgrade check values corresponding to different modules to be upgraded may be different.
According to the method, after the upgrading of the intelligent electric meter is completed, the data verification is carried out on the program code integrity of the upgraded module, whether the upgrading is successful or not is further checked, and the influence on the subsequent normal use of the intelligent electric meter is avoided.
Further, a third embodiment of the electric meter upgrading method according to the first embodiment and the second embodiment of the electric meter upgrading method of the present application is provided, in this embodiment, before step S30, the method further includes:
step S70, storing the original file corresponding to the module to be upgraded before upgrading;
the step S62 further includes:
and step S63, controlling the module to be upgraded to roll back to the version before updating according to the original file corresponding to the module to be upgraded.
In this embodiment, after the upgrade file of each module to be upgraded is obtained through analysis, the current program code of each module to be upgraded is not immediately replaced, but the current program code of each module to be upgraded is backed up before upgrade to generate and store the corresponding original file of the module to be upgraded. Therefore, after the upgrading failure of the module to be upgraded is determined, the original file of the module to be upgraded which fails to be upgraded can be called, and the module to be upgraded is controlled to roll back to the version before being upgraded, so that the problem that the intelligent electric meter cannot be normally used due to the upgrading failure of the module to be upgraded is avoided.
In this embodiment, an original file before updating of a module to be upgraded is stored; and if the module to be upgraded fails to be upgraded, controlling the module to be upgraded to roll back to the version before being upgraded according to the original file. When the module to be upgraded fails to be upgraded, the version before being upgraded is automatically recovered and the module is normally started, so that the normal use of the user on the intelligent electric meter cannot be influenced no matter whether the upgrading is successful or failed, and the user experience is improved.
Further, referring to fig. 3, fig. 3 is a flowchart illustrating a fourth embodiment of the electric meter upgrading method according to the foregoing embodiment of the electric meter upgrading method, in this embodiment, step S20 includes:
step S21, carrying out data verification on the upgrade package;
and step S22, when the data verification is successful, analyzing the upgrade package to obtain the initial address, the function address list and the upgrade file corresponding to the module to be upgraded.
In this embodiment, when the server sends the upgrade package, the server also sends data verification information corresponding to the upgrade package, and determines whether the upgrade package has file loss during transmission by verifying the data verification information. Optionally, the check information in the upgrade package is automatically generated by a preset algorithm, in this embodiment, the data check information may be generated by using a CRC32 algorithm, and correspondingly, the smart meter performs data check on the upgrade package according to a CRC32 algorithm, which of course, this embodiment does not specifically limit the generation manner of the data check information. If the data verification is successful, the upgrading package obtained by the intelligent electric meter is a complete file package, and after the data verification is successful, the upgrading package is analyzed to obtain an initial address, a function address list and an upgrading file corresponding to the module to be upgraded. Further, when the data verification is unsuccessful, verification failure information can be sent to the server, and the server can resend the upgrade package to the intelligent electric meter after receiving the verification failure information.
In this embodiment, through the above manner, after the smart electric meter has completely received the upgrade package, data verification is performed again, and it is further ensured that the upgrade package is analyzed under the condition that the upgrade package is complete, so as to improve the upgrade success rate of the electric energy meter.
Further, referring to fig. 4, fig. 4 is a fifth embodiment of the electric meter upgrading method according to the foregoing embodiment of the electric meter upgrading method, in this embodiment, step S30 further includes:
step S31, obtaining the type of the module to be upgraded, wherein the type comprises an illegal type and a legal type;
step S32, if the type of the module to be upgraded is illegal, upgrading the module to be upgraded according to the initial address and the upgrade file corresponding to the module to be upgraded;
step S33, if the type of the module to be upgraded is legal, judging whether the upgrade package has a digital authentication certificate;
and step S34, when the digital authentication certificate exists in the upgrade package, upgrading the module to be upgraded according to the initial address and the upgrade file corresponding to the module to be upgraded.
In this embodiment, the software program of the smart meter further includes a non-legal part and an illegal part, so the types to which the correspondingly divided modules belong also include a legal type and an illegal type. For the legal part, before upgrading or modifying, the upgrading and modifying can be carried out only by re-authenticating the certification authority, and when the upgrading relates to the legal part, the server can package the digital certification certificate re-authenticated by the certification authority in the upgrading package. Therefore, in the upgrading process, the type of the module to be upgraded is obtained first, and the obtained type of the module to be upgraded can determine whether the module to be upgraded is a legal type or a non-legal type by obtaining a preset identifier of the module to be upgraded, for example, if the identifier is 1, the module to be upgraded is the legal type, and if the identifier is 0, the module to be upgraded is an illegal type. And when the type of the module to be upgraded is an illegal fixed type, directly upgrading the module to be upgraded according to the initial address and the upgrading file corresponding to the module to be upgraded. And when the type of the module to be upgraded is legal, judging whether the digital authentication certificate is analyzed from the upgrade package, and upgrading the module to be upgraded according to the initial address and the upgrade file corresponding to the module to be upgraded only when the digital authentication certificate is determined to exist.
The embodiment determines whether the upgrade package has the authority to upgrade the legal type module by judging whether the upgrade package has the digital authentication certificate. Thereby preventing illegal tampering with the quorum of program code.
Further, referring to fig. 5, fig. 5 is a sixth embodiment of the electric meter upgrading method according to the foregoing embodiment of the electric meter upgrading method, in this embodiment, before step S10, the method further includes:
step S80, receiving an upgrade configuration file sent by a server, carrying out upgrade detection on each module according to the upgrade configuration file, and determining a module to be upgraded;
step S90, sending an upgrade request including the identification information of the module to be upgraded to the server.
In this embodiment, the smart meter may receive an upgrade configuration file sent by the server at an irregular or regular time, where the configuration file may include version information of each module divided in the smart meter, and the smart meter may compare version information of each module configured in the configuration file with version information of a corresponding module in the smart meter in sequence, so as to determine which modules need to be upgraded, and determine the modules that need to be upgraded as modules to be upgraded. Then, the smart electric meter sends the identification information of the module to be upgraded to the server. The server packages the corresponding upgrade file of the module to be upgraded, the initial address of the module to be upgraded, the new function list address of the module to be upgraded and the upgrade check value of the module to be upgraded together to form an upgrade package according to the received identification information of the module to be upgraded, generates check information of the upgrade package by adopting a check algorithm, and feeds the upgrade package and the check information of the upgrade package back to the intelligent electric meter so that the intelligent electric meter completes the subsequent upgrade process.
It should be noted that, the obtaining of the start address of the module to be upgraded by the server may be obtained by querying from a mapping relation table, in which identification information of each module and the start address are stored in advance, in the server. Or after the intelligent electric meter determines the module to be upgraded, the identification information of the module to be upgraded and the corresponding initial address are sent to the server together.
