Background
At present, after mass delivery, when firmware is updated or upgraded, the electric meter is usually upgraded remotely, specifically in a point-to-point or broadcast manner through a master station. And upgrading the issued file to be an upgrading file of a submodule APP in the electric meter or an upgrading package of the whole firmware file. Through laboratory tests, the situation of upgrading failure with certain probability can occur in the current mode.
At present, the electric meter is technically upgraded and is mainly issued by means of a real-time file package of a master station. Specifically, under the conventional condition, the master station issues the firmware upgrade package in a broadcast mode, if the communication state is normal, most of the electric meters can successfully receive all upgrade data, a small part of the electric meters still exist, and the upgrade data frame is lost. And then, the master station cyclically issues a version reading command, and if a certain block is found to be not updated successfully, the master station acquires the frame data failed to be received aiming at the issued reading bitmap information command. Then, the data frame number with low receiving success rate is counted according to the main station. And the data frames which are not successfully received are sent one by one in a broadcasting or point-to-point mode. After repeated reissue, the method can meet the index requirement of successful upgrade. When the functional module in the ammeter is upgraded, the main station broadcasts to send the upgrading data frame to the ammeter, and then the ammeter transmits the upgrading data frame to the module for upgrading. If the upgrade data frame fails to be received, the master station still reads the version and bitmap information of each target module, and broadcasts or issues point to point again.

In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating an electricity meter upgrading method according to an embodiment of the present invention.
The electric meter upgrading method provided by the embodiment of the invention is particularly applied to the subordinate node, and the subordinate node is usually arranged between a master station and a communication link of each electric meter. The master station may be connected to one or more subordinate nodes, which are usually connected to a plurality, even a plurality, of groups of electric meters, which may be embodied as terminals or concentrators or the like. With regard to the specific structure of the subordinate node, reference may be made to the prior art, and the following electric meter upgrading method is specific to the flow specifically executed by the subordinate node.
Referring to fig. 1, in an embodiment of the present invention, an electricity meter upgrading method includes:
s101: and acquiring the upgrade file and the strategy parameters sent by the master station.
In this step, the master station may issue the upgrade file and the policy parameters to the subordinate nodes. The upgrading file is data required by upgrading of firmware in the electric meter, and the strategy parameters are parameters required by the subordinate nodes when the subordinate nodes send data to the electric meter. The specific content of the upgrade file needs to be set according to the actual situation, and the policy parameter may specifically include any one or any combination of the following: upgrading the model of the matching ammeter, the version of the matching hardware, the version of the current upgrading firmware, the time window for starting upgrading transmission, the time window for activating upgrading and the mask range of the address section of the upgrading ammeter.
The upgraded matching electric meter model, the matched hardware version and the current upgraded firmware version are screening conditions corresponding to the electric meter to be upgraded. In terms of hardware, in the subsequent steps, the subordinate node can screen out the electric meters to be upgraded from the plurality of electric meters according to the electric meter models and the hardware versions; and in the aspect of software, the subordinate node in the subsequent step can screen the electric meters to be upgraded from the plurality of electric meters according to the current firmware version of the electric meters and the mask range of the address section of the upgrading meter, so that the electric meters to be upgraded are upgraded in the subsequent step. And the upgrade transmission starting time window is the specific time when the subordinate node transmits the upgrade file to the ammeter, and the upgrade activation time window is the specific time when the subordinate node transmits an upgrade starting instruction to the ammeter to control the ammeter to be upgraded. Of course, in the embodiment of the present invention, the policy parameters may include other kinds of parameters, and are not specifically limited herein.
Specifically, the master station may issue the upgrade file and the policy parameter in a broadcast or peer-to-peer transmission manner, and the master station may issue the upgrade file and the policy parameter in a GPRS (General Packet Radio service), GSM (Global System for Mobile Communications), MODEM (MODEM), LAN (local area network), or other manners. In this step, after the lower node receives the policy parameter, the policy table stored in the lower node itself is updated according to the received policy parameter.
S102: and inquiring all strategy parameters of the corresponding upgrading files recorded in the strategy table.
In this step, the lower node may specifically query the policy parameters recorded in the policy table maintained by the lower node itself through timed auto-polling or other manners. And upgrading the electric meter according to the inquired strategy parameters in the subsequent steps. It should be noted that the policy parameters queried here may include, in addition to the policy parameters issued by the master station in S101, policy parameters pre-stored in a policy table maintained by the subordinate node itself, so as to ensure that the subordinate node can complete upgrading of the electric meter this time. Specifically, the upgrade file generally has different identification information, and the policy table maintained in the lower node may store policy parameters corresponding to different upgrade files. In this step, the policy parameters corresponding to the upgrade file to be updated at this time need to be queried, so as to update the electric meter in the subsequent steps.
S103: and when the current condition meets the inquired strategy parameters, the upgrading file is issued to the ammeter corresponding to the strategy parameters, so that the ammeter is upgraded according to the upgrading file.
In this step, when the current condition is required to meet the policy parameter queried from the policy table, for example, when the upgrade transmission start time window recorded in the policy parameter is from 2 to 4 am, when the current condition is from 2 to 4 am, that is, when the current condition meets the policy parameter queried from the policy table, the upgrade file acquired from the master station is sent to the electric meter corresponding to the policy parameter in a broadcast or point-to-point manner, so that the electric meter can be upgraded according to the upgrade file.
Specifically, when the next-level node issues the upgrade file in a point-to-point manner, a specific electric meter to be upgraded may be specifically selected to issue the upgrade file according to the information, such as the upgrade matching electric meter model, the matching hardware version, the current upgrade firmware version, the upgrade meter address field mask range, and the like, recorded in the policy parameter, and at this time, after the electric meter to be upgraded receives the upgrade file, a received message is usually returned to indicate that the upgrade file is received. When the next-level node issues the upgrade file in a broadcast manner, each electric meter is required to automatically determine whether the issued upgrade file is the corresponding upgrade file, and at this time, the upgrade file may include corresponding policy parameters. When corresponding, the electric meter can be upgraded according to the received upgrade file.
It should be noted that, the upgrading process of the electric meter is generally divided into two steps, where the first step is to receive an upgrade file, and the second step is to perform an upgrade operation through the upgrade file. And the electric meter generally needs to be upgraded according to an upgrade activation instruction issued by a lower node when the second step is executed. The upgrade activation instruction generally needs to be issued by the lower node according to the upgrade activation time window in the policy parameter. Of course, before the lower node issues the upgrade file, it is usually necessary to send an upgrade request to establish a connection with the corresponding electric meter, and specific contents thereof may refer to the prior art and are not described herein again.
It should be further noted that when the upgrade file sent by the next-level node specifically corresponds to a specific functional module in the electric meter, the electric meter is required to transfer again, and the electric meter generally transmits the received upgrade file to the corresponding functional module, so that the functional module can be upgraded according to the upgrade file. The specific content of the related module for upgrading according to the upgrade file may refer to the prior art, and is not described herein again.
The electric meter upgrading method provided by the embodiment of the invention is applied to a lower node, and comprises the steps of obtaining an upgrading file and strategy parameters sent by a main station; inquiring all strategy parameters of the corresponding upgrading files recorded in the strategy table; and when the current condition meets the inquired strategy parameters, the upgrading file is issued to the ammeter corresponding to the strategy parameters, so that the ammeter is upgraded according to the upgrading file.
The master station can independently upgrade the electric meters connected with the subordinate nodes according to the strategy parameters by issuing the upgrade files and the strategy parameters, so that frequent communication between the master station and the electric meters is avoided, and the pressure and the load of the master station can be reduced. And long-distance communication links between the master station and the electric meter are reduced, the possibility of external interference on communication is reduced, the communication efficiency is effectively improved, and the upgrading efficiency of the electric meter is improved.
The details of the method for upgrading an electricity meter according to the present invention will be described in detail in the following embodiments of the present invention.
Referring to fig. 2, fig. 2 is a flowchart illustrating a specific method for upgrading an electric meter according to an embodiment of the present invention.
Referring to fig. 2, in the embodiment of the present invention, an electricity meter upgrading method includes:
s201: and acquiring the upgrade file and the strategy parameters sent by the master station.
S202: and inquiring all strategy parameters of the corresponding upgrading files recorded in the strategy table.
S203: and when the current condition meets the inquired strategy parameters, the upgrading file is issued to the ammeter corresponding to the strategy parameters, so that the ammeter is upgraded according to the upgrading file.
S201 to S203 are substantially the same as S101 to S103 in the above embodiment of the invention, and for details, reference is made to the above embodiment of the invention, which is not repeated herein.
S204: when the electric meter does not receive all the upgrading files, the upgrading files are reissued to the electric meter which does not receive all the upgrading files according to reissuing strategy parameters included in the strategy parameters, and the electric meter is upgraded according to the reissued upgrading files.
In this step, whether the electric meters receive all the upgrade files or not can be checked in a manner that the electric meters report by themselves or a subordinate node polls each electric meter. When a certain electric meter does not receive all the upgrade files, the lower node in this step may execute a reissue policy, that is, reissue the upgrade files to the electric meter that does not receive all the upgrade files according to the reissue policy parameters included in the policy parameters recorded in the policy table, so as to promote the electric meter to upgrade.
Specifically, the reissue policy parameters generally include any one or any combination of the following: the method can adaptively select time, fixed reissue time, reissue retry times and a reissue transmission mode. Wherein the adaptive selection time, that is, the time for the lower node to adaptively perform the reissue operation, for example, the reissue operation when the channel is in an idle state in the morning is enabled; the fixed reissue time is the determined time for executing the reissue operation, the reissue retry number is the maximum number of times of the repeated execution allowed by the reissue, and the reissue transmission mode specifically includes broadcast or point-to-point transmission and the like. Of course, the reissue policy parameters may also include other contents, which may be set according to actual situations, and are not specifically limited herein.
In this step, the subordinate node reissues the upgrade file to the electric meter which does not acquire the upgrade file according to the reissue strategy parameter. In general, the reissue operation may be performed in a loop, but it has the maximum line-up. When the number of reissue operation cycles reaches the upper limit, the electric meter which has not received the complete upgrade file is determined to be damaged, and the return information needs to be reported to the master station. It should be noted that, in general, the lower node will issue the upgrade activation instruction after the reissue operation is completed, so that each electric meter performs the upgrade operation.
S205: and generating return information corresponding to the upgrading state of the electric meter, and uploading the return information to the master station.
When the reissue operation is completed, the subordinate node may generate a return message according to the upgrade status of each electric meter, and the upgrade status of each electric meter may be specifically reported by each electric meter actively or obtained by polling of the subordinate node, which is not specifically limited herein depending on the specific situation. And the subordinate node can generate return information corresponding to the upgrading state of the electric meters and upload the generated return information to the main station, so that an operator can inquire corresponding information from the main station and check the upgrading state of each electric meter. For the electric meters which are always failed to be upgraded, the subordinate nodes can specifically read the software version and report the software version back to the main station.
It should be noted that the lower node and the electric meter may be connected through other devices, such as a CCO (Central Coordinator), an STA (Station), and the like, which is not limited herein as the case may be.
According to the electric meter upgrading method provided by the embodiment of the invention, the main station can independently upgrade the electric meter connected with the subordinate node according to the strategy parameters under the condition of meeting the strategy parameters by issuing the upgrading file and the strategy parameters, so that frequent communication between the main station and the electric meter is avoided, and the pressure and load of the main station can be reduced. And long-distance communication links between the master station and the electric meter are reduced, the possibility of external interference on communication is reduced, the communication efficiency is effectively improved, and the upgrading efficiency of the electric meter is improved.
