All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate in order to describe the embodiments of the invention herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

For convenience of description, the following will describe some terms or terminology involved in the embodiments of the present invention:

bsdiff algorithm (binary differential patch ): the bsdiff difference algorithm is an algorithm for generating a binary difference patch by comparing binary data of two files to generate a piece of metadata describing a difference between a source file and a target file, and then merging the source file difference portion with the target file using the metadata to generate a new target file.

According to the embodiment of the invention, a power distribution terminal upgrading method is provided.

Fig. 1 is a flowchart of a power distribution terminal upgrade method according to an embodiment of the present invention. Applied to an edge computing device, as shown in fig. 1, the method comprises the steps of:

step S101, an initial differential upgrade package issued by a cloud master station is received.

For example, as shown in fig. 2, an edge computing node on an edge computing device receives an initial differential upgrade packet sent by a cloud master station by using a bsdiff differential algorithm, and stores the initial differential upgrade packet to a data center of the edge computing node. The bsdiff algorithm is a file difference algorithm based on an approximate matching theory, firstly, an old version firmware file is read, dictionary ordering is carried out on the file suffix, the suffix ordering algorithm is used for calculating and generating a suffix ordering array, then the suffix ordering array is used for traversing new firmware to find out sequences which are identical to the old firmware, and the identical sequences are expanded to two sides according to the matching degree between the new firmware and the old firmware. If there is a code in the new firmware that does not match any region in the old firmware, it is stored as difference data in the difference packet. After the differential file output by the differential algorithm is transmitted to the terminal of the power distribution Internet of things, the embedded system can restore the new firmware by utilizing the differential file and the old firmware in the system.

Step S102, triggering an upgrade starting instruction, receiving an instruction verification result for verifying whether the upgrade starting instruction is a preset instruction sent by the power distribution terminal, and processing the initial differential upgrade package to obtain N target differential upgrade packages under the condition that the instruction verification result indicates that the upgrade starting instruction is the preset instruction, wherein the preset instruction is an instruction for starting and upgrading the initial differential upgrade package, and N is an integer larger than 1.

The method comprises the steps of triggering a starting upgrading instruction through an edge computing node, issuing the starting upgrading instruction to a power distribution terminal, verifying whether the starting upgrading instruction is a preset instruction through the power distribution terminal, receiving an instruction verification result issued by the power distribution terminal, if the starting upgrading instruction is equal to the preset instruction, indicating that the starting upgrading instruction is a correct upgrading instruction, and executing subsequent sub-packaging operation on an initial differential upgrading packet.

Specifically, the instruction for triggering and starting the upgrade is received, and the instruction verification result for verifying whether the instruction for starting the upgrade is a preset instruction sent by the power distribution terminal can be obtained through the following steps: triggering a starting upgrading instruction and acquiring an upgrading instruction packet of the starting upgrading instruction; issuing an upgrade instruction packet to the power distribution terminal so that the power distribution terminal verifies whether the upgrade instruction is a preset instruction according to the upgrade instruction packet; and receiving an instruction verification result of the starting upgrading instruction sent by the power distribution terminal.

The power distribution terminal calculates whether the CRC check code in the start-up upgrade instruction packet is equal to the CRC check code of the terminal node or not, if the CRC check code and the CRC check code are not equal to each other, the start-up upgrade instruction is not a correct preset instruction, namely, the instruction is not an instruction for starting up upgrade to the initial differential upgrade packet, if the CRC check code and the CRC check code are equal to each other, the start-up upgrade instruction is a correct upgrade instruction, and subsequent processing operation to the initial differential upgrade packet is executed.

In order to reduce network congestion rate and improve upgrading success rate, the method processes the initial differential upgrading packet to obtain N target differential upgrading packets, and the method specifically comprises the following steps: splitting the initial differential upgrade package into N parts to obtain N differential upgrade packages; and carrying out software configuration on the N differential upgrade packages respectively to obtain N corresponding target differential upgrade packages.

For example, the initial differential upgrade packet may be divided into 8 or 16 separate differential upgrade packets according to a 1:8 or 1:16 manner, and each single packet is identified and numbered, and a program upgrade flag bit is set, where the identification number is used to record the serial number of the single packet, and the program upgrade flag bit is used to indicate whether the single packet has been received. Wherein, N target differential upgrade packages respectively include: single package identification, single package program, check code, program upgrade identification.

Specifically, as shown in fig. 3, the software configuration performed on the N differential upgrade packages may be a single Bao Bianhao configuration, a single package program configuration, a package CRC (cyclic redundancy check code), and a program upgrade flag bit, where:

(1) Single Bao Bianhao: the identification number used to represent the package is, for example, 1,2,3.

(2) Single package procedure: representing the specific contents of the package.

(3) Package CRC: the check code is a common check code in the communication field, the check on the communication reliability is needed, the check is carried out from the data itself, the check is carried out by means of a certain mathematical agreed form, the check result is reliable or unreliable, the data is processed if the check result is reliable, and the retransmission is discarded or the repair is carried out if the check result is unreliable.

(4) Program upgrade flag bit: the method is used for identifying the currently received program package, and is used for indicating that the package program is not received in time 0 and indicating that the package program is received in time 1. Whether the terminal node receives the single packet can be known by checking the program upgrading flag bit, and if the single packet is received, starting upgrading after receiving all the single packets; if the single packet is not received, selecting to resend the single packet from the edge computing node in a broadcasting mode according to the number of the terminal nodes which do not receive the single packet, or finishing accurate supplementary packet of the single packet through the handheld terminal.

The invention improves the upgrading efficiency of the terminal nodes by sub-packaging the initial differential upgrading packet, and ensures the consistency and accuracy of upgrading a large number of terminal nodes at the bottom.

Step S103, triggering an instruction to be upgraded, and sequentially issuing N target differential upgrade packages to the power distribution terminal, wherein the triggering time for starting the upgrade instruction is earlier than the triggering time of the instruction to be upgraded.

Under the condition that the verification starting upgrading instruction is a correct preset instruction, the to-be-upgraded instruction is triggered, and the integrity verification is carried out on a plurality of target differential upgrading packages sent to the power distribution terminal through a multiple verification mechanism, so that the follow-up upgrading accuracy and reliability of the power distribution terminal are improved.

Specifically, if there are multiple power distribution terminals of the same type, triggering an instruction to be upgraded, and sequentially issuing N target differential upgrade packages to the power distribution terminals, including: if the fact that the target power distribution terminals do not receive the preset target differential upgrade package is detected in the power distribution terminals, the number of the target power distribution terminals is obtained, wherein the preset target differential upgrade package is at least one of N target differential upgrade packages; if the number of the target power distribution terminals is greater than a preset threshold value, a preset target differential upgrade package is re-issued to the target power distribution terminals in a broadcasting mode; and if the number of the target power distribution terminals is smaller than or equal to the preset threshold value, the preset target differential upgrade package is re-issued to the target power distribution terminals through the handheld terminal.

The number of the edge computing nodes of the edge computing equipment is 20, N independent target differential upgrade packages are sequentially issued to the 20 power distribution terminals in a broadcast mode, the broadcast times can be set for 5 times, then terminal node program upgrade flag bits of the power distribution terminals are checked in real time, it can be known that the terminal nodes of the power distribution terminals do not receive the N-1 th and/or N-5 th preset target differential upgrade packages, for example, the number of the nodes of the 20 power distribution terminals which do not receive the two single packages is counted to be 10, the number is considered to be 5% of the number of the whole terminal nodes, the edge computing nodes send the single packages to the target power distribution terminals again in a broadcast mode, otherwise, the hand-held terminals carry out point-to-point supplementary packages to the target power distribution terminals which do not receive the single packages.

Specifically, if the number of the target power distribution terminals is smaller than or equal to the preset threshold, the preset target differential upgrade package is re-issued to the target power distribution terminals through the handheld terminal, and the method can be obtained through the following steps: and sending a package supplementing request to the cloud master station, so that the cloud master station sends the package supplementing request to the handheld terminal in a wireless communication mode, and the handheld terminal can send the preset target differential upgrade package to the target power distribution terminal again, wherein the package supplementing request is a request for resending the preset target differential upgrade package.

If the number of the terminal nodes of the target power distribution terminals in the plurality of power distribution terminals does not receive the N-1 preset target differential upgrade packet, counting the number of the nodes of the target power distribution terminals which do not receive the single packet in the 30 power distribution terminals as 1, and considering that the number is not more than 5% of the number of the whole terminal nodes, sending a package supplementing request to a cloud master station, enabling the cloud master station to send the package supplementing request to a handheld terminal in a wireless communication mode, and performing point-to-point package supplementing on the target power distribution terminals which do not receive the single packet through the handheld terminal.
