Background
In the application of AMI centralized meter reading, an electric meter communication module (usually a PLC carrier communication module or an RF wireless communication module) is often used for networking meter reading. When the module firmware is upgraded, the firmware of millions of ammeter communication modules on the spot needs to be upgraded. The upgrading message adopts conventional networking routing relay communication, the upgrading firmware message sent by the concentrator is transmitted through a multi-level routing, and after the upgrading operation is finished, the firmware version of each module needs to be read to verify whether the module is upgraded successfully. Such a firmware upgrade method has the following disadvantages:
(1) The upgrading time is long: the upgrading firmware message sent by the concentrator is transmitted through a multi-level route, and after the upgrading operation is completed, the firmware version of each module needs to be copied and read to verify whether the module is upgraded successfully. Upgrading the firmware of all the meter communication modules of a city often requires tens of days or months.
(2) The upgrading engineering is complex: due to poor upgrading effect, the version is copied and checked after each upgrading operation, and the process relates to the operation and communication processes of a master station, a concentrator and an ammeter communication module, and is complex and time-consuming.
(3) The upgrade success rate is low: because the success rate of networking network communication cannot reach 100% for each concentrator, the firmware of the ammeter communication module of some distribution areas cannot be upgraded.
(4) The iteration cycle of the product is long: due to the slow upgrade speed, the optimized firmware cannot be tested with fast iterations.
In summary, the existing firmware upgrading method adopts a networking routing relay communication mode, and the concentrator upgrades all the ammeter communication modules of the network, so that the problems of long upgrading time, complex upgrading process, low upgrading success rate, low upgrading speed and the like exist.

It should be understood that, the sequence numbers of the steps in the following embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Referring to fig. 1, a flowchart of a firmware upgrading method for a networking module according to an embodiment of the present invention is shown, where the firmware upgrading method for the networking module is applicable to firmware upgrading of an Advanced Metering Infrastructure (AMI) field networking (Programmable Logic Controller (PLC)) module or a Radio Frequency (RF) wireless communication module.
In the invention, the concentrator has the function of upgrading the firmware of the communication modules of the surrounding electric meters, each communication module of the electric meters also has the function of upgrading the firmware of other communication modules of the surrounding electric meters, but only the communication module of the electric meters which finishes the firmware upgrading stores a firmware upgrading program, the starting upgrading command sent by the concentrator can be received and executed, and the communication module of the electric meters which finishes the firmware upgrading can start the firmware upgrading operation of the communication modules of the electric meters which do not finish the upgrading of the surroundings thereof only after receiving the starting upgrading command sent by the concentrator.
As shown in fig. 1, the firmware upgrading method of the networking module may include the following steps:
step 1, upgrading the ammeter communication modules around the concentrator by the concentrator, and finishing the firmware upgrading of at least 1 ammeter communication module;
the concentrator can upgrade 100% of electricity meter communication modules within the stable communication range of the concentrator, so that the concentrator can upgrade the surrounding electricity meter communication modules, and the firmware of at least 1 electricity meter communication module can be upgraded.
As another embodiment, in order to accurately know the number of the electric meter communication modules successfully upgraded by the concentrator, the firmware version of the electric meter communication modules around the concentrator may be verified.
Step 2, the concentrator sends a start upgrading command to the ammeter communication module which finishes firmware upgrading at present, the ammeter communication module which finishes firmware upgrading at present receives and executes the start upgrading command sent by the concentrator, and firmware upgrading operation is carried out on the ammeter communication modules which do not finish firmware upgrading at the periphery of the concentrator;
step 3, when the times of sending the upgrading starting command by the concentrator is less than the first set times, circularly executing the step 2; and when the number of times of sending the upgrading starting command by the concentrator is equal to the first set number of times, all the ammeter communication modules finish firmware upgrading.
It is easy to understand that, because the step 2 is executed in a circulating manner when the number of times that the concentrator sends the start upgrading command is less than the first set number of times, and in each circulation, the concentrator sends the start upgrading command to the 'electric meter communication module with the firmware upgraded at present', the concentrator can send the start upgrading command for multiple times in the invention.
During the first circulation, the concentrator sends a first start upgrading command, the 'ammeter communication module with the upgraded firmware at present' is the ammeter communication module with the upgraded firmware in the step 1, and after the modules perform firmware upgrading operation on the ammeter communication modules with the incomplete firmware upgrading around the modules according to the first start upgrading command, some ammeter communication modules with the incomplete firmware upgrading can be upgraded successfully, so that the ammeter communication modules with the upgraded firmware in the network can be increased; and in the second circulation, the concentrator sends a second start upgrading command, and the current' ammeter communication module with firmware upgraded is the ammeter communication module with firmware upgraded in the step 1 plus the newly added ammeter communication module with firmware upgraded after the first start upgrading command is executed, namely all the ammeter communication modules with firmware upgraded in the network when the second start upgrading command is sent. And by analogy, each starting upgrading command is sent to all the ammeter communication modules which finish firmware upgrading when the starting upgrading command is sent by the concentrator, namely, each starting upgrading command is received and executed by all the ammeter communication modules which finish firmware upgrading when the starting upgrading command is sent by the concentrator until all the ammeter communication modules finish firmware upgrading.
In this embodiment, the concentrator periodically sends the start-up upgrade command in the broadcast communication mode, and when the number of times that the concentrator sends the start-up upgrade command is greater than or equal to a first set number of times, all the ammeter communication modules are considered to complete firmware upgrade. The first set number is determined according to the number of times that all the ammeter communication modules actually need to complete firmware upgrade, and generally, the first set number is larger than the number of times that all the ammeter communication modules actually need to complete firmware upgrade. In order to ensure that all the electric meter communication modules can complete firmware upgrade, that is, upgrade to 100% of power, the first set number of times may be set to be 2 to 3 times of the actual number of times that all the electric meter communication modules complete firmware upgrade, for example: if the actually required number of times is 20 times, the first set number of times may be set to 50 times.
In this embodiment, the time interval for the concentrator to send the start-up upgrade command at regular time is determined according to the time for completing one firmware upgrade operation. Assuming that the time for completing one firmware upgrade operation is m minutes, the time interval for the concentrator to periodically send the start upgrade command may be set to m + k minutes, where k is greater than or equal to 1. For example, the time for completing one firmware upgrade operation is 25 minutes, and the time interval for the concentrator to periodically transmit the start upgrade command may be set to 30 minutes.
In this embodiment, the concentrator sends the upgrade start command in the broadcast communication mode, which can simplify the upgrade process.
In an embodiment, the concentrator sends the start-up upgrade command for multiple times, not necessarily at a fixed time, but also may send the start-up upgrade command for multiple times according to a command issued by the master station.
Referring to fig. 2, which is a schematic view of a firmware upgrading operation process of a method for upgrading firmware of a networking module according to an embodiment of the present invention, for convenience of description, a device a is used to represent an electric meter communication module with firmware upgrade completed, and a device B is used to represent an electric meter communication module with firmware upgrade not completed.
As shown in fig. 2, the process of performing the firmware upgrade operation is as follows:
step 1, equipment A sends an upgrading frame lack request to equipment B around the equipment A; the upgrade missing frame request comprises: the hardware version, the software version, the size of an upgrade file, the checksum of all firmware messages and the checksum of the message of the upgraded product;
step 2, the device B checks whether the stored firmware message is complete and correct according to the received upgrading frame missing request; if the result is complete and correct, upgrading bootstrap is executed; otherwise, returning an upgrade missing frame response to the equipment A, and telling the equipment A which upgrade file sub-messages need to be downloaded in a supplementing manner; the upgrading of the frame missing response comprises the following steps: the sequence number of the missing upgrade file sub-message;
step 3, the equipment A waits for collecting upgrading frame lack responses sent by the equipment B around the equipment A:
if the equipment A receives the upgrade frame missing response, entering the step 4; if the device A does not receive the upgrade frame missing response, counting 1 frame missing request failure, and then entering step 5;
step 4, the equipment A sends a supplementary upgrade firmware message to the surrounding equipment B according to the received upgrade frame missing response; the supplementary firmware upgrade message includes: the upgraded product hardware version, software version, the supplemented upgrade file sub-message, the message size and sequence number, and the checksum of the message; after receiving the supplemented upgrade firmware message, the device B performs supplementary update on the firmware message stored by the device B;
step 5, when the counted number of times of frame missing request failure is larger than a second set number of times, the firmware upgrading operation is finished; otherwise, returning to the step 1;
and 6, repeating the process until the time length used by the firmware upgrading operation is longer than the set time length, and ending the firmware upgrading operation. Namely, after the device a performs firmware upgrading operation on the surrounding devices B, the firmware upgrading operation is automatically stopped after the device a continuously upgrades for a set time.
In this embodiment, the set time period is set to 25 minutes. As another embodiment, the value of the set duration may be set according to the actual requirement.
In this embodiment, the second set number of times is set to 20 times. As another embodiment, the value of the second set number of times may be set according to actual requirements.
In step 2 of this embodiment, a process for checking whether a firmware packet stored by the device B is complete and correct according to the received update-missing-frame request includes:
(1) Checking whether the upgrading frame lacking request stored before is the same as the upgrading frame lacking request received at the time, if the upgrading frame lacking request is different from the upgrading frame lacking request, clearing all downloaded information, storing the upgrading frame lacking request, and then returning an upgrading frame lacking response to the equipment A; in this case, the returned upgrade-deficient frame response tells the device a that all the upgrade file sub-messages need to be downloaded in a supplementing manner;
(2) If the firmware message is the same as the firmware message, checking whether the stored firmware message is complete, and if the firmware message is incomplete, returning an upgrading missing frame response to the ammeter communication module which finishes firmware upgrading; in this case, the returned upgrade-deficient frame response tells the device a that it needs to supplement and download the missing upgrade file sub-message;
(3) If the firmware upgrading is complete, checking whether the stored check sum of all firmware messages is correct, if not, clearing all downloaded information, storing the upgrading frame missing request, and then returning upgrading frame missing response to the ammeter communication module which finishes firmware upgrading; in this case, the returned upgrade-deficient frame response tells the device a that all the upgrade file sub-messages need to be downloaded in a supplementing manner;
(4) If so, the device B performs upgrade bootstrapping.
It should be noted that the firmware upgrade operation shown in fig. 2 occurs after the current start upgrade command is sent and before the next start upgrade command is sent, so that after the device B executes the upgrade bootstrap, although the device B becomes the device a that newly completes the firmware upgrade, it does not execute the firmware upgrade operation on the other electric meter communication modules, and only when the concentrator sends the next start upgrade command, the device a that newly completes the firmware upgrade will receive and execute the start upgrade command.
In this embodiment, the device a executes firmware upgrade operations (including broadcast transmission of an upgrade missing frame request, broadcast transmission of an upgrade missing frame response, broadcast transmission of a supplementary upgrade firmware packet, and the like) to the devices B around the device a in the broadcast communication mode, which can simplify the upgrade process. As another embodiment, the device a may also perform the firmware upgrade operation only to the device B within the stable communication range of the device a in the multicast communication mode.
In the actual application, there may be a plurality of devices a, so that there is a case where a plurality of devices a perform firmware upgrade operations on the same device B, because the firmware upgrade operations are to split a new program file into hundreds of pieces of sub information for download transmission, and the download process is broadcast transmission, the same device B can receive the new program file sub information sent by the plurality of devices a, and the new program file sub information sent by any device a can be stored in the device B as long as the device B itself lacks the information.
Meanwhile, because a plurality of devices B are available in actual application, the situation that the same device A receives the upgrade-deficient frame responses from a plurality of devices B exists, namely after one device A broadcasts and sends an upgrade-deficient frame request, all the devices B which receive the upgrade-deficient frame request (only self-checking contains deficient frames) will randomly contend for and answer the deficient frames. In this embodiment, if the device a receives 1 to multiple update-missing frame responses this time, the device a groups a "total missing frame number list", where the "total missing frame number list" includes the update file sub-packet numbers missing from multiple devices B, and the device a broadcasts and sends a supplementary update firmware packet to multiple surrounding devices B according to the "total missing frame number list", and each device B receives the supplementary update firmware packet and then performs supplementary update on the firmware packet stored in itself.
With reference to fig. 3-1 to fig. 3-8, the upgrade process of the firmware upgrade method of the networking module of the present invention is described by taking a platform area and a concentrator as an example. In the figure, the electric meter communication module firmware of the gray frame electric meter is not upgraded; and the electric meter communication module firmware of the black frame electric meter is upgraded.
The firmware upgrading process for one platform area and one concentrator is as follows:
(1) As shown in fig. 3-1, the concentrator first upgrades the electric meter communication modules around the concentrator until the firmware upgrade of at least 1 electric meter communication module is completed;
as shown in fig. 3-2, in this embodiment, the concentrator completes the firmware upgrade of 1 meter communication module, that is, the firmware upgrade of the communication module of the meter a is successful.
(2) As shown in fig. 3-3, the concentrator commands the communication module of the electric meter a that has completed firmware upgrade to perform firmware upgrade operation on the electric meter communication modules that do not complete firmware upgrade around the communication module;
as shown in fig. 3-4, in the embodiment, if the communication module of the electric meter a is successfully upgraded by 8 electric meter communication modules, there are 9 electric meter communication modules whose firmware upgrade has been completed in the network.
(3) As shown in fig. 3-5, the concentrator instructs the 9 electric meter communication modules whose firmware upgrade has been completed to perform firmware upgrade operation on the electric meter communication modules whose firmware upgrade has not been completed around the concentrator;
as can be seen from fig. 3-5, only 7 meter communication modules with firmware upgrade are surrounded by meter communication modules that have not been upgraded successfully. For the 2 electric meter communication modules which are positioned in the two circular intersection areas and have finished firmware upgrading, no electric meter communication module which is not upgraded successfully exists around the electric meter communication modules, so that after receiving and executing an upgrading starting command sent by the concentrator, the electric meter communication modules send out upgrading-deficient frame requests, and finally, the firmware upgrading operation is ended when the counted number of times of failed frame-deficient requests is greater than a second set number of times, so that the 2 electric meter communication modules cannot upgrade any electric meter communication module successfully until the whole upgrading process is ended.
As shown in fig. 3-6, if the upgrade is successful for 13 meter communication modules again, there are 22 meter communication modules with firmware upgraded in the network.
(4) As shown in fig. 3-7, the concentrator commands the successfully-upgraded 22 electric meter communication modules to perform firmware upgrade operations on their respective peripheral electric meter communication modules that do not complete firmware upgrade;
as shown in fig. 3 to 8, in this embodiment, 5 electric meter communication modules are upgraded again successfully.
Therefore, all the electric meter communication modules in the station area are upgraded.
In this embodiment, the concentrator finishes the firmware upgrade work of all the ammeter communication modules in the local area only by sending the upgrade starting command for 3 times, and the upgrade speed is very high. In addition, the more the number of the ammeter communication modules for finishing firmware upgrading by the concentrator in the first step is, the faster the upgrading speed of the ammeter communication modules is.
In summary, when the firmware is upgraded, the concentrator first upgrades the firmware of the ammeter communication modules around the concentrator to obtain at least 1 ammeter communication module for completing the firmware upgrade; and then, the concentrator sends an upgrading starting command to the ammeter communication module with the upgraded firmware, and the ammeter communication module with the upgraded firmware is used for upgrading other ammeter communication modules without the upgraded firmware. That is to say, the electric meter communication module (hereinafter referred to as upgraded module) having completed firmware upgrade in the present invention has the function of upgrading the electric meter communication module, so that the firmware upgrading mode of upgrading all the electric meter communication modules of the network by the concentrator in the prior art is changed into the upgrading mode by the "module upgrading module".
The upgrading mode of the module upgrading module has the advantages of simple upgrading process, high upgrading speed and high upgrading success rate, and specifically comprises the following steps:
(1) The upgrading speed is high; the concentrator can send a plurality of starting upgrading commands, all the upgraded modules are received and executed when the starting upgrading command is sent out by the starting upgrading command each time, and after the starting upgrading command is executed each time, the number of the upgraded modules in the network can be increased compared with the number of the upgraded modules in the previous time, so that the number of the upgraded modules participating in the execution of the next starting upgrading command can be more, and the upgraded modules participating in the execution of the starting upgrading command can be more and the upgrading speed can be faster along with the increase of the sending times of the starting upgrading command. And the firmware of all the electric meter communication modules in one city is upgraded for only 1 to 2 days.
