For better explaining the embodiments of the present application, please refer to fig. 2, fig. 2 is a flow chart of an upgrade file sending method provided by the present application, based on the above embodiments:
as a preferred embodiment, the sending of the upgrade file to the electric energy meter to be upgraded specifically includes:
broadcasting all upgrade packages required by upgrade to the electric energy meter to be upgraded;
specifically, considering that the electric energy meter to be upgraded has limited acceptable data quantity at each time, the upgrade file needs to be divided into a plurality of upgrade packages to be sent, so that the electric energy meter to be upgraded can be successfully received.
The method comprises the steps of performing package supplementing on the electric energy meter to be upgraded with a package loss phenomenon;
considering that some electric energy meters to be upgraded are likely to have the phenomenon of packet loss after the upgrade packet is broadcast, in order to enable each electric energy meter to be upgraded to be successfully upgraded, the electric energy meters to be upgraded with the packet loss need to be subjected to packet supplementing.
And checking whether an upgrade package received by the electric energy meter to be upgraded has errors or not, and if not, ending.
Specifically, considering that even if the upgrade package is received completely, the received upgrade package may have errors, so that the whole upgrade package received by the electric energy meter to be upgraded needs to be checked, if no errors exist, the upgrade program of the electric energy meter to be upgraded can be ended, if errors exist, the version broadcasted to all electric energy meters to be upgraded may not be suitable, and the upgrade file of the suitable version is likely to need to be retransmitted.
The step of verifying whether the upgrade package received by the electric energy meter to be upgraded has errors or not specifically may be to send a verification code to the electric energy meter to be upgraded, the electric energy meter to be upgraded may verify whether the received upgrade file has errors or not according to the verification code, and feedback the result to the concentrator.
As a preferred embodiment, broadcasting all the upgrade packages required for the upgrade to the electric energy meter to be upgraded is specifically:
step S201: reading the size rated value of an upgrade package of the electric energy meter to be upgraded;
step S202: dividing the upgrade file into upgrade packs with the upgrade pack size rated value;
step S203: and broadcasting all the obtained upgrade packages to the electric energy meter to be upgraded.
Specifically, the rated value of the size of the upgrade package represents the data quantity which can be received by the electric energy meter to be upgraded each time, and after the rated value of the size of the upgrade package is obtained, the concentrator can divide the upgrade file into the upgrade package of the rated value of the size of the upgrade package and broadcast the upgrade package.
The method comprises the steps of broadcasting for a plurality of times, wherein the broadcasting can be carried out for a plurality of times during broadcasting, so that all electric energy meters to be upgraded can completely receive all upgrading packages.
The size rating of the upgrade package may be various, for example, 128B or 256B, and the embodiment of the present application is not limited herein.
Specifically, the size of the last upgrade package may not reach the rated value of the upgrade package, but this does not affect the splicing process of the electric energy meter to the upgrade package.
As a preferred embodiment, the method for supplementing the to-be-upgraded electric energy meter with the packet loss phenomenon specifically comprises the following steps:
step S204: reading an upgrade package state of the electric energy meter to be upgraded with a preset serial number;
step S205: judging whether the electric energy meter to be upgraded receives all the upgrade packages according to the upgrade package state;
step S206: if not, broadcasting the lost upgrade package of the electric energy meter to be upgraded, and executing the step of reading the status of the upgrade package of the electric energy meter to be upgraded;
step S207: if all the upgrade packages are received, adding one to the preset sequence number;
step S208: judging whether an electric energy meter with a preset serial number exists or not;
step S209: if yes, executing the step of reading the state of an upgrade package of the electric energy meter to be upgraded with the preset serial number;
step S210: if not, the check is ended.
Specifically, when the electric energy meter to be upgraded with the packet loss phenomenon is subjected to packet supplementing, the electric energy meter to be upgraded needs to be checked one by one and the packet loss electric energy meter to be upgraded needs to be subjected to packet supplementing, wherein when the packet supplementing is performed, the lost upgrade packet is broadcast instead of unicast, and the reason is that all the electric energy meters to be upgraded are of the same type generally, and the same packet loss is likely to occur in the electric energy meter to be upgraded of the same type, so that the embodiment of the application can broadcast the lost upgrade packet instead of unicast, and further improve the working efficiency.
In the upgrade package state, a value (e.g., 0 or 1) of each digit may represent whether a corresponding upgrade package has been received, and a value of 1 may represent that a corresponding upgrade package has been received, and a value of 0 may represent that a corresponding upgrade package has not been received.
As a preferred embodiment, the sending, to the electric energy meter to be upgraded, an upgrade initialization instruction including a preset upgrade time is specifically:
an upgrade initialization instruction containing preset upgrade time is sent to the electric energy meter to be upgraded through the pre-connection client of the electric energy meter;
the method for reading the size rated value of the upgrade package of the electric energy meter to be upgraded comprises the following steps:
reading the size rated value of an upgrade package of the electric energy meter to be upgraded through a pre-connection client;
the broadcasting of all the upgrade packages obtained by segmentation to the electric energy meter to be upgraded is specifically as follows:
broadcasting all the obtained upgrade packages to the electric energy meter to be upgraded through the pre-connection client;
the state of the upgrade package of the electric energy meter to be upgraded for reading the preset serial number is specifically as follows:
reading an upgrade package state of the electric energy meter to be upgraded with a preset serial number through a pre-connection client;
the step of checking whether the upgrade package received by the electric energy meter to be upgraded has errors is specifically as follows:
and checking whether an upgrade package received by the electric energy meter to be upgraded has errors or not through the pre-connection client.
Specifically, considering that when the concentrator upgrades the electric energy meter, a plurality of control actions including upgrading initialization and reading the state of an upgrade package are all required to be carried out through the management client, however, when the concentrator communicates with the electric energy meter to be upgraded through the management client each time, a period of time is required to be spent for establishing communication connection, so that the working efficiency is reduced, and when the concentrator upgrades the electric energy meter, the concentrator can always communicate with the electric energy meter to be upgraded through the pre-connection client, a data path is not required to be established before data interaction, so that the working efficiency is improved, and when the pre-connection client sends data to the electric energy meter, the unique preset secret key can be used for encrypting, then each electric energy meter can be decrypted through the preset secret key after receiving the encrypted data, and the concentrator also does not need to manage the secret passwords of each electric energy meter (in the prior art, because the concentrator sends the data to the electric energy meter through the management client, the secret passwords of each electric energy meter are required to be used in encryption), and the security of the secret passwords is improved.
It should be noted that, when the concentrator broadcasts all the upgrade packages or broadcasts the complementary upgrade packages, the pre-connection client is adopted, and this usually requires a long time, however, the default time of the management client is usually short (for example, 3 min), that is, after each broadcast, the management client also needs to take time to establish a data path with the electric energy meter again, which reduces the working efficiency.
As a preferred embodiment, the upgrade initialization instruction further comprises upgrade file expiration time;
the upgrade file expiration time is used to control the validity of the upgrade file.
Specifically, considering that the version corresponding to the upgrade file has timeliness, after too long, the upgrade file is not suitable for the electric energy meter at that time, so that the upgrade file failure time can be added in the upgrade initialization instruction in the embodiment of the application, namely, after the upgrade file failure time is passed, the upgrade file corresponding to the upgrade file failure time is not allowed to be activated any more, and the electric energy meter is prevented from faults after the failed upgrade file is activated.
When verifying whether the upgrade package is received in error, whether the failure time of the upgrade file is reached can be judged at the same time, and if the failure time is reached, the upgrade package is received in error.
