Description

Technical Field

[0001] The present invention relates to the technical field of smart electric meters, and in particular to an electric energy meter upgrading method, device and system. Background Art

[0002] The electric energy meter is an electric energy metering device installed by the electric energy seller at the electric energy demand side. The electric energy seller charges the corresponding fee by referring to the measurement value in the electric energy meter. As the functions of smart electric energy meters are relatively complex, the electric energy meters that have been installed on site may need to be upgraded to perform functional iterations and fix bugs. The internal program of the smart electric energy meter consists of two parts: the boot program and the application program. The boot program is used to start and upgrade the electric energy meter, and the application program is used to execute the actual business (it is this part of the program that is changed during the upgrade).

[0003] The upgrade process of the energy meter is to transmit the upgrade package to the energy meter through the host computer or the master station system. The entire energy meter upgrade process is quite unreliable, and the unreliable factors include communication interference, internal self-programming interference of the energy meter, data jump, etc. For these reasons, the energy meter will place a backup memory or additional storage space inside to back up the old application and important operating data before the upgrade. If the upgrade fails, the energy meter can call back the old application and data in the backup memory to restore them to the original state to prevent the energy meter from failing to upgrade and failing to operate normally.

[0004] However, the above upgrade process requires the addition of additional backup memory or storage space, which increases the hardware cost. At the same time, the old application and important data need to be backed up to the backup memory before the upgrade. Since the amount of data is very large, it takes a long time to copy. For a large number of installed electric energy meters, this time consumption will be a huge workload when upgrading in batches. Summary of the invention

[0005] In view of this, the present invention provides an electric energy meter upgrade method, device and system to solve the problem that the electric energy meter upgrade method in the prior art needs to add additional backup memory or storage space, which increases hardware costs.

[0006] In a first aspect, the present invention provides an electric energy meter upgrade method, which is applied to the electric energy meter, and the method comprises: receiving a block data frame containing block data of an upgrade package sent by an upgrade server; extracting data to be backed up of corresponding size according to the size of the block data in the block data frame for backing up; erasing the original data to be backed up, and writing the received block data into an erase area; loading the backed-up data into a reply frame of successful writing and sending it to the upgrade server; repeatedly receiving the block data frame, backing up the data, erasing and writing the block data until all the block data in the upgrade package are written.

[0007] In the present invention, when the electric energy meter is upgraded, the upgrade package is sent to the electric energy meter in blocks. After receiving each block data frame, the electric energy meter backs up the corresponding size of the data to be backed up, erases the original data, writes the received block data to the corresponding position of the original data, and then loads the backup data into the reply frame of successful writing and sends them to the upgrade server. In this upgrade method, the data to be backed up can be directly sent to the upgrade server for storage with the reply frame, which takes a short time, and there is no need to set up additional backup storage space or backup memory, which reduces the hardware cost.

[0008] In an optional embodiment, receiving a block data frame of an upgrade package sent by an upgrade server includes: receiving an upgrade request frame sent by the upgrade server; sending an upgrade consent frame to the upgrade server according to the upgrade request frame; and receiving a block data frame containing upgrade package block data sent by the upgrade server according to the upgrade consent frame.

[0009] In the present invention, before sending the block data frame, an upgrade request frame is first sent to inquire whether the electric energy meter is upgraded, and the block data frame is sent after confirming the upgrade, so as to avoid unnecessary data transmission and reduce unnecessary waste of resources.

[0012] In the present invention, after the block data is written, an upgrade check frame sent by the upgrade server is received. When the upgrade fails, the upgrade server can resend the previously saved backup data to the electric energy meter so that the electric energy meter can be restored to its original state when the upgrade fails, thereby not affecting the normal operation of the electric energy meter.

[0013] In a second aspect, the present invention provides a method for upgrading an electric energy meter, which is applied to an upgrade server, and the method comprises: sending a block data frame containing block data of an upgrade package to the electric energy meter; receiving a reply frame indicating successful writing sent by the electric energy meter, wherein the reply frame is generated after the electric energy meter backs up the corresponding size of data to be backed up and then erases it, and writes the block data frame in the erase area; the reply frame is loaded with backup data; the backup data in the reply frame is stored; and the steps of sending the block data frame to the electric energy meter, receiving the reply frame, and storing the backup data in the reply frame are repeated until all the block data in the upgrade package are sent.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0025] According to an embodiment of the present invention, an embodiment of an electric energy meter upgrading method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0026] In this embodiment, a method for upgrading an electric energy meter is provided, which is used for the electric energy meter. Figure 1 is a flow chart of a method for upgrading an electric energy meter according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps: Step S101, receiving a block data frame containing block data of an upgrade package sent by an upgrade server. Specifically, when the electric energy meter needs to upgrade the application program, the upgrade server sends the upgrade package to the electric energy meter. At the same time, since the upgrade package contains a large amount of data, in order to improve transmission efficiency, enhance reliability and compatibility, and adapt to different network conditions, the upgrade package is divided into multiple data blocks during transmission, that is, a block data frame containing one block data is sent each time. The size of each block data can be determined according to actual conditions, for example, each block data can be tens of KB or several MB. Among them, the upgrade server can be a device that stores the upgrade package, for example, it can be a host computer or a master station system.

[0027] Step S102, extracting the corresponding size of the data to be backed up for backup according to the size of the block data in the block data frame. Specifically, after the electric energy meter receives a block data frame, a block of code of the corresponding size is extracted from the internal application or important operation data thereof as the data to be backed up according to the size of the block elements in the block data frame. The size of the extracted data to be backed up can be the same as the size of the received block data, so that the received block data can be written. The extracted data to be backed up can be backed up in the running memory RAM (Random Access Memory). The extraction and backup process can be understood as copying part of the data from the application or important operation data running before the electric energy meter is upgraded, and saving it in the running memory. Among them, whether the important operation data needs to be backed up can be preset or determined by the user according to the actual situation.

[0028] It should be noted that since the block data is obtained by dividing the upgrade package into blocks, that is, each block data is usually not very large, the data to be backed up extracted based on the size of the block data will not be very large either. Therefore, there is no need to set up additional backup memory or storage space in the electric energy meter, and the extracted data to be backed up can be directly stored in the running memory.

[0029] Step S103, the original data to be backed up is erased, and the received block data is written into the erase area. Specifically, after the corresponding application or important operation data, i.e., the data to be backed up, is backed up, this part of data can be erased from the original application or important operation data, and then the received block data is written into the erase area, so as to realize the update and replacement of the application.

[0030] Step S104, load the backup data into a successful write reply frame and send it to the upgrade server. Specifically, when the block data is written successfully, a successful write reply frame is generated, and the backup data stored in the running memory is loaded into the reply frame, and then the reply frame is sent to the upgrade server.

[0031] Step S105, repeatedly receiving block data frames, data backup, erasing and writing of block data, until all block data in the upgrade package are written. Specifically, the writing of one block data is realized through the above steps S101 to S104. The upgrade package includes multiple block data, so other block data can also be written with reference to the above steps S101 to S104, that is, multiple block data frames can be sent to the electric energy meter in sequence, and the electric energy meter executes the above steps S101 to S104 in sequence, and repeatedly receives, backs up, erases and writes block data for each block data frame, until all block data in the upgrade package are written. Thereby completing the upgrade process of the electric energy meter.

[0032] The electric energy meter upgrade method provided by the embodiment of the present invention, when the electric energy meter is upgraded, the upgrade package is sent to the electric energy meter in blocks. After the electric energy meter receives each block data frame, the corresponding size of the data to be backed up is backed up, the original data is erased, and the received block data is written to the corresponding position of the original data, and then the backup data is loaded into the reply frame of successful writing and sent to the upgrade server together. In this upgrade method, the data to be backed up can be directly sent to the upgrade server for storage with the reply frame, which takes a short time, and there is no need to set up additional backup storage space or backup memory, which reduces the hardware cost.

[0033] In this embodiment, a method for upgrading an electric energy meter is provided. The method is applied to an electric energy meter and comprises the following steps: Step S201: receiving a block data frame containing block data of an upgrade package sent by an upgrade server.

[0034] Specifically, the above step S201 includes: Step S2011, receiving an upgrade request frame sent by the upgrade server; specifically, after relevant personnel update the function of the application in the electric energy meter or generate an upgrade package for bug fixes, the upgrade server can send an upgrade request frame to the electric energy meter, that is, asking the electric energy meter whether to upgrade.

[0035] Step S2012, sending an upgrade consent frame to the upgrade server according to the upgrade request frame; specifically, after the electric energy meter receives the upgrade request frame, if the upgrade is agreed, the upgrade consent frame can be replied to the upgrade server; if the upgrade is not agreed, the data frame of not upgrading can be replied to the upgrade server.

[0036] Step S2013, receiving a block data frame containing block data of the upgrade package sent by the upgrade server according to the upgrade consent frame. Specifically, when the upgrade server receives the upgrade consent frame, it can divide the upgrade package into multiple block data, and then send the block data to the electric energy meter. If a data frame not to upgrade is received, the upgrade can be canceled and the subsequent process will not be executed.

[0037] It should be noted that the upgrade server can send upgrade request frames to multiple electric energy meters at the same time. After each electric energy meter receives the upgrade request frame, if it agrees to upgrade, it can send an upgrade consent frame to the upgrade server. After the electric energy meter receives the upgrade consent frame sent by any electric energy meter, it can send a block data frame to it. For the electric energy meter that has not sent the upgrade consent frame, the block data frame will no longer be sent to it.

[0038] Step S202: extract the corresponding size of the to-be-backed data according to the size of the block data in the block data frame for backup. Figure 1 Step S102 of the illustrated embodiment will not be described in detail here.

[0039] Step S203, the original data to be backed up is erased, and the received block data is written into the erase area; Figure 1 Step S103 of the illustrated embodiment will not be described in detail here.

[0040] Step S204: Load the backup data into a write-success reply frame and send it to the upgrade server. Figure 1 Step S104 of the illustrated embodiment will not be described in detail here.

[0041] Step S205, receiving an upgrade check frame sent by the upgrade server; generating an upgrade success reply frame or an upgrade failure reply frame according to the upgrade check frame and sending it to the upgrade server.

[0042] Specifically, after the upgrade server has sent all the block data frames in the upgrade package, it can continue to send upgrade check frames to the electric energy meter. After all the block data are written, the electric energy meter can be upgraded based on the written block data and determine whether the upgrade is successful. After the electric energy meter receives the upgrade check frame sent by the upgrade server, it replies to the generation server according to the result of whether the upgrade is successful. For example, if the upgrade is successful, a reply frame of upgrade success is sent to the upgrade server, and if the upgrade fails, a reply frame of upgrade failure is sent to the upgrade server.

[0043] Step S206, receiving backup data sent by the upgrade server through a private protocol, wherein the backup data is sent by the upgrade server when no reply is received within a preset time after receiving a reply frame of upgrade failure or sending an upgrade check frame; and rewriting the received backup data.

[0044] Specifically, when the upgrade server receives a reply frame indicating an upgrade failure sent by the electric energy meter within a preset time or does not receive a reply frame within a certain period of time after sending an upgrade check frame, it is determined that the electric energy meter upgrade has failed, and the saved backup data is sent to the electric energy meter through a private protocol. After receiving the backup data, the electric energy meter can erase the written block data and rewrite the received backup data, thereby restoring the electric energy meter to its original state. The electric energy meter includes a boot program and an application program. The upgrade process is for upgrading the application program, and the private protocol runs in the reference program. Even if the application program fails to upgrade, the operation of the private protocol is not affected by the application, that is, data transmission can also be performed through the private protocol.

[0045] In this embodiment, a method for upgrading an electric energy meter is provided, which is applied to upgrading a server, such as Figure 2 As shown, the method comprises the following steps: Step S301: sending a block data frame containing block data of an upgrade package to an electric energy meter.

[0046] Step S302, receiving a reply frame indicating successful writing sent by the electric energy meter, wherein the reply frame is generated after the electric energy meter erases the corresponding size of the data to be backed up and writes the block data frame in the erase area; the reply frame is loaded with the backup data.

[0047] Step S303: store the backup data in the reply frame.

[0048] Step S304, repeating the steps of sending the block data frame to the electric energy meter, receiving the reply frame, and storing the backup data in the reply frame until all the block data in the upgrade package are sent.

[0049] The further functional description of each of the above steps is the same as that of the corresponding embodiments of the above steps S101 to S104, and will not be repeated here.

[0050] In this embodiment, a method for upgrading an electric energy meter is provided, which is applied to an upgrading server. The method comprises the following steps: Step S401: sending a block data frame containing block data of an upgrade package to an electric energy meter.

[0051] Specifically, the above step S401 includes: Step S4011, sending an upgrade request frame to the electric energy meter.

[0052] Step S4012: receiving an upgrade approval frame sent by the electric energy meter based on the upgrade request frame.

[0053] Step S4013: sending a block data frame containing block data of the upgrade package to the electric energy meter based on the upgrade consent frame.

[0054] Step S402, receiving a write success reply frame sent by the electric energy meter, wherein the reply frame is generated after the electric energy meter erases the corresponding size of the backed-up data and writes the block data frame in the erase area; the reply frame is loaded with the backup data.

[0055] Step S403: store the backup data in the reply frame.

[0056] Step S404, repeating the steps of sending the block data frame to the electric energy meter, receiving the reply frame, and storing the backup data in the reply frame until all the block data frames in the upgrade package are sent.

[0057] Step S405, sending an upgrade check frame to the electric energy meter; when a reply frame indicating an upgrade failure sent by the electric energy meter based on the upgrade check frame is received within a preset time or a reply frame from the electric energy meter is not received within the preset time, sending the saved backup data to the electric energy meter through a private protocol.

[0077] As a specific application example of the embodiment of the present invention, Figure 6 As shown, the electric energy meter upgrade system can work according to the following process: (1) The host computer or master station system sends an upgrade request frame to one or more electricity meters.

[0078] (2) After receiving the upgrade request frame, if the electric energy meter agrees to upgrade, it replies with an upgrade consent frame.

[0079] (3) After the host computer or the master station system receives the upgrade consent frame sent by the electric energy meter, it sends a block data frame (for example, 200 bytes) of the new upgrade package to the corresponding electric energy meter.

[0080] (4) After receiving the block data frame, the electric energy meter first extracts a block of code (200 bytes) of the old application, temporarily backs it up in the running memory RAM, and then erases this part of the code of the old application.

[0081] (5) The electric energy meter writes the block data in the block data frame received in step "(3)" into the erase area in step "(4)", that is, replaces it with the new application.

[0082] (6) After data writing is completed, the data block backed up in the RAM is loaded into the reply frame and replied to the host computer or the master station system. The host computer and the master station system save this data.

[0084] (8) The host computer or master station system initiates an upgrade check frame.

[0085] (9) If the meter replies that the upgrade is successful, the upgrade is complete. If the meter fails to reply or does not respond, the upgrade fails.

[0086] (10) If the upgrade fails, the host computer and the master station system directly send the backup data to the energy meter through a private protocol to restore it to its original state. The private protocol only runs in the boot program and is not affected by the upgrade failure.
