Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the specification. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Fig. 1a illustrates an application environment of the present application, in which an electricity meter may include an upgrade processing means and an upgrade execution means; the upgrade processing device may be configured to process an upgrade file, where processing the upgrade file may be, for example, format conversion of the upgrade file, and generating corresponding file description information according to the upgrade file (the file description information may be used to determine the upgrade file), and the upgrade execution device may be configured to execute an upgrade operation according to the processed upgrade file, for example, load an upgrade instruction in the processed upgrade file into the processor, so that the processor runs the upgrade instruction (the processed upgrade file may be the converted upgrade file); specifically, the method comprises the following steps: after the electric meter receives the original upgrading file, the upgrading processing device verifies the original upgrading file, and after the verification of the original upgrading file is passed, the original upgrading file is converted according to the upgrading format of the upgrading execution device to obtain a converted upgrading file; the upgrade processing device generates an upgrade instruction according to the converted upgrade file and sends the upgrade instruction to the upgrade execution device; and after receiving the upgrading instruction sent by the upgrading processing device, the upgrading execution device determines a corresponding conversion upgrading file and executes the upgrading of the software of the electric meter management unit according to the determined conversion upgrading file.
In some embodiments of the present application, a two-core smart meter is taken as an example for description, and it should not be understood here as a limitation on the upgrading method of the meter management unit software or the meter, etc. in the present application; the original upgrade file may be sent to the electricity meter by a computer device such as a server, and the server may be implemented by an independent server or a server cluster composed of a plurality of servers. Fig. 1b shows another application scenario of the present application, in which the server may be the master station, that is, the master station sends the original upgrade file to the electricity meter.
In one embodiment, as shown in fig. 2, a method for upgrading software of a management unit of a two-core smart meter is provided, which is described by taking the method as an example of being applied to the two-core smart meter (in the following description, it may be simply referred to as a meter) in fig. 1a, and includes the following steps:
step S202, the original upgrade file is verified; and the original upgrading file is used for upgrading the software of the electric meter management unit in the electric meter.
The original upgrade file may carry upgrade information for upgrading the electric meter management unit software (it may be understood that the corresponding electric meter management unit software may be referred to as electric meter management unit software to be upgraded); the original file may be generated according to an original communication protocol between the sender and the meter. The upgrading information can comprise information such as the version number of the electric meter management unit software to be upgraded, the document size, the storage path in the electric meter and the like; the upgrade execution device may determine the electricity meter management unit software to be upgraded according to the upgrade information, and execute the upgrade of the electricity meter management unit software.
In the step, a sending end (such as a master station) sends an original upgrading file to an electric meter, and an upgrading processing device in the electric meter checks the original upgrading file; verifying the content may include verifying whether a transmitting end that transmits the original upgrade file is legal and whether the original upgrade file is complete, that is, verifying the original upgrade file by the upgrade processing apparatus may include verifying the validity of the transmitting end and the integrity of the original upgrade file.
And step S204, if the verification is passed, converting the original upgrade file according to the upgrade format of the upgrade execution device to obtain a converted upgrade file.
Because the upgrade execution device does not encapsulate the communication protocol between the electric meters, the upgrade execution device cannot directly execute the upgrade according to the original upgrade file sent by the master station. Therefore, in this step, the upgrade processing device completes the verification of the original upgrade file, and after it is determined that the original upgrade file passes the verification, the upgrade processing device converts the original upgrade file according to the upgrade format of the upgrade execution device, and obtains a converted upgrade file conforming to the upgrade format of the upgrade execution device.
Furthermore, the upgrading processing device is packaged with a communication protocol between the electric meters, and the upgrading processing device can analyze the original upgrading file according to the packaged communication protocol to obtain upgrading information; the upgrade processing device can send the upgrade information to a format conversion function of the upgrade execution device for format conversion to obtain a conversion upgrade file; the format conversion function is preset with the upgrading format of the upgrading execution device and is used for converting the original upgrading file according to the upgrading format.
Specifically, the upgrade processing device analyzes the original upgrade file according to the communication protocol to obtain upgrade information, inputs the upgrade information to the format conversion function, and the format conversion function performs format conversion processing on the input upgrade information according to a preset upgrade format to obtain a conversion upgrade file and returns the conversion upgrade file to the upgrade processing device.
And step S206, generating an upgrading instruction according to the conversion upgrading file.
After the upgrade processing device obtains the conversion upgrade file, the conversion upgrade file can be directly loaded into the upgrade instruction, the conversion upgrade file can also be stored in a memory of the ammeter, file description information such as a storage path and a file name of the conversion upgrade file is obtained, and the upgrade instruction is generated according to the file description information.
And step S208, sending the upgrading instruction to an upgrading execution device.
The upgrading processing device generates an upgrading instruction according to the converted upgrading file and then sends the upgrading instruction to the upgrading execution device; after receiving the upgrading instruction, the upgrading execution device determines a corresponding conversion upgrading file according to the upgrading instruction, and because the conversion upgrading software conforms to the upgrading format of the upgrading execution device, the upgrading execution device can execute the upgrading of the software of the electric meter management unit according to the conversion upgrading file.
In some scenarios, when upgrading the software of the electric meter management unit, the upgrade execution device needs to upgrade according to the preset upgrade activation time, and therefore, in order to upgrade the upgrade execution device in accordance with the preset upgrade activation time, not in other time periods, the upgrade processing device may send the upgrade instruction to the upgrade execution device when the current time is in accordance with the preset upgrade activation time. Fig. 3 is a schematic flow chart illustrating that the upgrade processing device sends an upgrade instruction according to the upgrade activation time, and introduces a corresponding method with reference to fig. 3: step S302, after the electric meter receives preset upgrade activation time sent by a master station, step S304, an upgrade processing device of the electric meter judges whether the upgrade activation time is sent by a legal master station, step S306, if so, the upgrade processing device judges whether upgrade state characters are started image activation, step S308, if so, current time is obtained, step S310, the current time is judged to accord with the upgrade activation time, step S312, if accord with (the condition of being accordant with the upgrade activation time can comprise that the current time is accordant with the upgrade activation time, or the upgrade activation time is historical time relative to the current time), an upgrade instruction is sent to an upgrade execution device, so that the upgrade execution device can immediately execute the upgrade of management unit software of the electric meter; if not, the upgrade processing apparatus returns to step S306, continues to determine whether the upgrade state word is activated for the boot image, and reads the current time and determines whether the current time matches the upgrade activation time under the condition that the upgrade state word is activated for the boot image.
Furthermore, in order to further simplify the modules included in the upgrade processing apparatus, the upgrade processing apparatus may obtain the current time by calling a corresponding interface in the upgrade execution apparatus to obtain the corresponding interface and return the current time.
In the conventional method for upgrading the software of the electric meter management unit, because the software of the electric meter management unit for realizing each function is integrated in the software system of the electric meter management unit, the coupling between the software (or applications) of the electric meter management unit is strong, if a certain new software (also called as software) of the electric meter management unit needs to be installed in the electric meter, the whole electric meter needs to be replaced, which is equivalent to installing the software system of the electric meter management unit in other electric meters, and the upgrading efficiency is reduced. When upgrading the electricity meter management unit software, processing operation for an upgrade file (may be simply referred to as upgrade processing operation) and upgrade execution operation are involved. The inventor finds that: the upgrading processing operation relates to an electric meter communication protocol with a master station, and the electric meter communication protocol is generally used between an electric meter and an electric meter or between the electric meter and the master station, that is, the upgrading processing operation is not applicable to all electric meters due to the specificity of the electric meter communication protocol; the upgrading execution operation is used for executing the upgrading operation according to the processed upgrading file, has universality and is suitable for all electric meters; if the upgrade processing operation and the upgrade execution operation are integrated into one device, the device needs to configure the same upgrade execution operation for different electricity meters, that is, the portability of the upgrade execution operation in the device is reduced, resulting in a reduction in the efficiency of upgrading the electricity meter management unit software.
Based on the method, the electric meter and the method for upgrading the electric meter management unit software are provided, the upgrading processing device and the upgrading execution device are arranged, the upgrading processing device is used for verifying and converting the format of the original upgrading file to obtain a converted upgrading file, and the original upgrading file is used for upgrading the electric meter management unit software; the upgrading processing device generates an upgrading instruction according to the conversion upgrading file and sends the upgrading instruction to the upgrading execution device, so that the upgrading execution device can determine the corresponding conversion upgrading file and execute the upgrading of the software of the electric meter management unit; the upgrading processing operation and the upgrading execution operation are respectively configured in the upgrading processing device and the upgrading execution device, so that the upgrading processing device can configure different ammeter communication protocols according to the actual conditions of all ammeters, the upgrading file of the ammeter management unit software is processed, the coupling between the ammeter management unit software is reduced, the upgrading efficiency of the ammeter management unit software is improved, the upgrading execution device can be suitable for other ammeters, the portability of the upgrading execution operation is improved, and the upgrading efficiency of the ammeter management unit software is improved.
In some embodiments, the upgrade processing apparatus may use different upgrade state words to represent different processing stages during processing of the original upgrade file, so that other applications may know the current processing progress; for example, if the upgrade state word is to be checked, it indicates that the current processing stage is to be checked on the original upgrade file, and for example, if the upgrade state word is to be downloaded (or loaded), it indicates that the current processing stage is to be loaded on the data frame of the original upgrade file. It should be noted that, in some embodiments, the references to "download" and "load" may be used to mean the same thing, and may be used to refer to: acquiring data transmitted by other terminals (such as a master station); in addition, the master station can also be understood as a sending end because the master station can send the original upgrade file to the electric meter.
In some embodiments, the upgrade processing device may prepare for upgrading before receiving the original upgrade file, so as to verify the original upgrade file. In the process of preparing for upgrading by the upgrade processing device and the master station, data in the process of preparing for upgrading can be forwarded by a virtual bus forwarding device in the electric meter, wherein the virtual bus forwarding device is used for forwarding data between the upgrade processing device and the master station and other sending terminals. Specifically, after receiving an upgrade preparation request sent by a master station, a virtual bus forwarding device analyzes the upgrade preparation request to obtain a data identifier carried in the upgrade preparation request, determines a corresponding upgrade processing device according to the data identifier, and forwards an upgrade accurate request to the corresponding upgrade processing device; after receiving an upgrade preparation request sent by a virtual bus forwarding device, an upgrade processing device performs upgrade preparation according to an upgrade accurate request; the process of performing upgrade preparation according to the upgrade preparation request may include: and analyzing the upgrade preparation request, and checking the legality of the sending end and the integrity of the original upgrade file according to the preparation information (such as the size of a preset data frame, a preset check code and a preset byte amount) obtained by analysis.
When the master station sends the original upgrading file to the ammeter, the original upgrading file can be segmented into a plurality of data frames, then the original upgrading file is sent to the ammeter in a data frame mode, and correspondingly, an upgrading processing device of the ammeter receives the data frames of the original upgrading file sent by the master station; in order to avoid errors in the transmission process of the data frame of the original upgrade file, the upgrade processing device can verify the data frame of the original upgrade file, and after the verification is passed, the upgrade processing device sends a data frame receiving response to the master station to trigger the master station to send the next data frame of the original upgrade file. Fig. 4 shows a flow in which the upgrade processing apparatus receives a data frame of an original upgrade file. The process is described in connection with fig. 4:
step S402, the virtual bus forwarding device analyzes the upgrade preparation request to obtain a data identifier carried in the upgrade preparation request, determines a corresponding upgrade processing device according to the data identifier, and forwards the upgrade accurate request to the corresponding upgrade processing device;
step S404, the upgrading processing device analyzes the upgrading preparation request to obtain the size of a preset data frame;
step S406, after receiving the data frame of the original upgrade file sent by the master station, the virtual bus forwarding device forwards the data frame to the upgrade processing device, the upgrade processing device judges the integrity of the data frame according to the size of the preset data frame, and if the data frame is not complete, the virtual bus forwarding device sends a corresponding response to the master station so that the master station returns the complete data frame of the original upgrade file;
step S408, if the data frame is complete, the upgrading processing device analyzes the data frame of the original upgrading file, and in the analyzing process, the upgrading processing device judges the type of the control code read-write request of the data;
step S410, if the upgrade processing device confirms that the control code of the data is a write request, judging the legality of the write data;
step S412, if the upgrading processing device confirms that the written data is legal, the upgrading state word can be modified to be downloaded;
step S414, if not, the upgrade processing device determines whether the request is a read request, step S416, if so, the upgrade processing device determines that the data can be extracted according to the data identifier in the read state, and determines that the data is in a normal state, and step S418, the upgrade processing device generates a corresponding normal response frame and sends the normal response frame to the virtual bus forwarding device; the virtual bus forwarding device generates a data frame receiving response according to the normal response frame, sends the data frame receiving response to the master station, and sends the next data frame of the original upgrade file to the ammeter after the master station receives the data frame receiving response;
step S420, if the upgrade processing device confirms that the written data is illegal or confirms that the control code of the data is not a writing request or a reading request, the upgrade processing device confirms that the data is in an abnormal state, generates an abnormal response frame and sends the abnormal response frame to the virtual bus forwarding device; and the virtual bus forwarding device generates a data frame retransmission response according to the abnormal response frame, sends the data frame retransmission response to the master station, and sends the data frame of the original upgrade file to the ammeter again after receiving the data frame retransmission response.
In some embodiments, if the upgrade preparation request may carry a preset check code and a preset byte amount, the upgrade processing device may further obtain the preset check code and the preset byte amount after analyzing the upgrade preparation request, and the preset check code and the preset byte amount are used for checking the original upgrade file; fig. 5 shows a process of verifying an original upgrade file by the upgrade processing apparatus, specifically:
step S502, after the upgrade processing device records the data frame of the original upgrade file, step S504, determining whether the data frame is legal, the determination process of this step may refer to the description of fig. 4, which is not described herein;
step S506, if the file is legal, loading the next data frame of the original upgrade file, and judging the validity of the next data frame in the step S504;
step S508, if not legal, recording the serial number of the current data frame, and sending a file missing response to the master station, where the specific content of this step is described below and will not be described in detail herein;
step S510, the upgrading processing device judges whether all data frames of the original upgrading file are loaded or not;
step S512, if all data frames are loaded, the upgrading processing device can change the upgrading state words into the data frames to be checked;
step S514, the upgrade processing device checks the original upgrade file;
step S516, the upgrading processing device judges whether the verification is successful;
step S518, if yes, determining that the sending end of the original upgrade file is a legal master station, and modifying the upgrade state word into a verification success;
step S520, if not, the verification of the original upgrade file is determined to be failed, and the upgrade state word is modified to be failed.
In step S514, when the upgrade processing device verifies the original upgrade file, the upgrade processing device may encrypt all data frames of the original upgrade file to obtain an actual check code, determine whether the actual check code is consistent with a preset check code, and if so, determine that the transmitting end is a legal master station; the upgrade processing device can also calculate the actual byte amount of all data frames of the original upgrade file, and if the actual byte amount is consistent with the preset byte amount, the upgrade processing device can determine that the original upgrade file is a complete upgrade file; the upgrade processing device can also judge that the original upgrade file passes the verification after determining that the validity of the sending end and the original upgrade file are complete upgrade files.
In step S508, when the upgrade processing device determines that the current data frame is illegal, the upgrade processing device may record a serial number of the failed current data frame, use the serial number as missing information, and send the missing information to the virtual bus forwarding device, and the virtual bus forwarding device generates a file missing response according to the missing information and sends the file missing response to the master station; and after receiving the file missing response sent by the electric meter, the master station analyzes the file missing response to obtain missing information, determines a corresponding missing data frame according to the missing information, and sends the missing data frame serving as missing data to the electric meter so that the upgrading processing device receives the missing data.
In one scenario, if only one electric meter fails to be loaded, the master station can send the missing data to the electric meter in a point-to-point transmission mode; if the loading of a plurality of electric meters fails, the main station can send the missing data to the plurality of electric meters in a broadcast transmission mode. Specifically, after receiving a file missing response returned by the electric meter, the master station judges the number of the received file missing responses, if only one file missing response is confirmed, the corresponding missing data is sent to the corresponding electric meter in a point-to-point transmission mode, the missing data is sent to a specific electric meter in the point-to-point transmission mode, and transmission resources of a network are saved; if the file missing responses corresponding to different electric meters are confirmed, namely different file missing responses are sent by different electric meters, the master station can send the missing data to each electric meter in a broadcast transmission mode at the moment, so that the corresponding upgrading processing device can receive the missing data, and the upgrading efficiency of the electric meter management unit software can be improved by sending the missing data in the broadcast transmission mode.
In some application scenarios, in order to further improve the upgrading efficiency of the software of the electric meter management unit, the upgrading processing device sends an upgrading instruction to the upgrading execution device through an upgrading calling interface of the upgrading execution device; fig. 4 shows an interaction flow among the virtual bus forwarding device, the upgrade processing device, and the upgrade executing device in the electric meter, and a process of the upgrade processing device sending the upgrade instruction to the upgrade executing device through the upgrade invoking interface is introduced with reference to fig. 4:
(1) an upgrade preparation stage:
the virtual bus forwarding device receives an upgrade preparation request sent by the master station, and sends the upgrade preparation request to the upgrade processing device, the upgrade processing device reads and writes data and loads a current data frame after receiving the upgrade preparation request, and sends a data frame receiving response to the virtual bus forwarding device after the upgrade processing device finishes loading the data frame, and the virtual bus forwarding device forwards the data frame receiving response to the master station so that the master station sends the next data frame of an original upgrade file; after the upgrade processing device has loaded all the data frames of the original upgrade file, the upgrade processing device may be considered to complete the preparation for upgrade.
