The communication between the real-time control area and the non-control production area and the communication between the production management area and the management information area are all isolated by a firewall, and the communication between the real-time control area and the production management area and the communication between the non-control production area and the production management area are all isolated by a network safety isolation device, so that the data sharing requirement of interval service application between the areas is met.

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.

The power grid monitoring system data transmission method based on hash algorithm fragmentation and recombination can be applied to the application environment shown in fig. 1. Wherein the transport server 102 communicates with the quarantine server 104 over a network. The transmission server 102 determines storage addresses corresponding to the plurality of target storages, respectively; the transmission server 102 fragments data to be transmitted to obtain a plurality of fragment data, and labels each fragment data to obtain a fragment identifier corresponding to each fragment data; the transmission server 102 makes one-to-one correspondence between the fragment identifier and the storage address and establishes an index relationship to obtain a hash data table; the transmission server 102 stores each piece of data into a target memory designated by the corresponding memory address according to the memory address corresponding to the corresponding fragment identifier; the transmission server 102 generates a data transmission request based on the fragment identifier and the hash data table, and sends the data transmission request to the isolated server, so that the isolated server obtains each piece of data from the target storage based on the hash data table and the fragment identifier carried in the data transmission request. The server 104 may be implemented as a stand-alone server or a server cluster composed of a plurality of servers.

In an embodiment, as shown in fig. 2, a method for transmitting data of a power grid monitoring system based on hash algorithm fragmentation and reassembly is provided, which is described by taking the method applied to the transmission server in fig. 1 as an example, and includes the following steps:

in step S202, memory addresses corresponding to the plurality of target memories are determined.

The memory is a memory unit for storing data, instructions, and the like.

Specifically, the transfer server determines a plurality of target memories from the plurality of memories, and determines storage addresses corresponding to the respective target memories based on the plurality of target memories.

Step S204, the data to be transmitted is sliced to obtain a plurality of pieces of data, and each piece of data is respectively marked to obtain a respective corresponding slicing identifier of each piece of data.

The fragment mark comprises a character label of data to be transmitted to which each piece of data belongs, and a sequence label of each piece of data is determined.

Specifically, the transmission server performs fragmentation processing on data to be transmitted to obtain a plurality of pieces of data corresponding to the data to be transmitted, and performs labeling processing on each piece of data to obtain a fragment identifier corresponding to each piece of data.

For example, the transmission server performs fragmentation processing on data to be transmitted a to obtain 10 pieces of data, performs labeling processing on each piece of data, and obtains corresponding fragment identifiers of the piece of data, which may be a-0001, a-0002, … …, or a-0010. Taking the slice data a-0001 as an example, wherein the character a is a character identifier of data to be transmitted to which each slice data belongs, the character identifier is a unique identifier of the slice data, 0001 is a sequence label, the sequence label can be characterized in a numerical arrangement form, and the sequence of each slice data is determined based on the sequence label.

Step S206, the fragment identification and the storage address are in one-to-one correspondence, and an index relationship is established, so that a hash data table is obtained.

The hash data table maps the key value to a position in the table to realize the accessed data result, so that the searching speed is accelerated.

Specifically, the transmission server determines a storage address corresponding to each fragment identifier through a hash algorithm based on the fragment identifier of each piece of data and the storage address of each target storage, determines a corresponding relationship between each fragment identifier and the storage address, and establishes an index relationship based on the corresponding relationship to obtain a hash data table.

Step S208, storing each piece of data into the target memory specified by the corresponding storage address according to the storage address corresponding to the corresponding fragment identifier.

Specifically, the transmission server stores each piece of data into the target memory specified by the corresponding storage address according to the storage address corresponding to the corresponding fragment identifier based on the correspondence between the fragment identifier and the storage address, for example, the transmission server stores the piece of data into the corresponding target memory in sequence from small to large based on the sequence number corresponding to the fragment identifier according to the correspondence between the fragment identifier and the storage address.

Step S210, generating a data transmission request based on the fragment identifier and the hash data table, and sending the data transmission request to the isolated server, so that the isolated server obtains each piece of data from the target storage based on the hash data table and the fragment identifier carried in the data transmission request.

Specifically, the transmission server generates a data transmission request carrying the hash data table and the fragment identifier based on the fragment identifier and the hash data table, and sends the data transmission request to the isolation server, so that the isolation server obtains the hash data table and the fragment identifier based on the data transmission request, and obtains corresponding pieces of data from each target storage based on the hash data table and the fragment identifier.

For example, the transmission server generates a data transmission request based on the fragment identifier and the hash data table, and sends the data transmission request to the isolation server, so that the isolation server performs information query based on the hash data table and the fragment identifier carried in the data transmission request, to respectively access the target memories corresponding to the pieces of data, and to obtain the pieces of data from the target memories.

In the power grid monitoring system data transmission method based on hash algorithm fragmentation and reassembly, the data to be transmitted is fragmented by determining storage addresses corresponding to a plurality of target memories respectively to obtain a plurality of pieces of data, each piece of data is labeled respectively to obtain fragmentation identifications corresponding to each piece of data, the fragmentation identifications and the storage addresses are in one-to-one correspondence, and an index relationship is established to obtain a hash data table; the method comprises the steps of storing each piece of data into a target memory appointed by the corresponding memory address according to the memory address corresponding to the corresponding piece identification, rapidly and accurately confirming the target memory stored with the piece of data according to a hash data table, generating a data transmission request based on the piece identification and the hash data table, and sending the data transmission request to an isolation server, so that the isolation server obtains each piece of data from the target memory based on the hash data table and the piece identification carried in the data transmission request.

In one embodiment, the slicing the data to be transmitted to obtain a plurality of pieces of data includes: acquiring the total data volume of data to be transmitted, and taking the number of target memories as the number of piece data; determining a unit data amount of each slice data based on the number of the slice data and the total data amount; and slicing the data to be transmitted according to the unit data quantity to obtain a plurality of pieces of data.

Specifically, the transmission server obtains the total data volume of the data to be transmitted and the number of the target memories respectively, the number of the target memories is used as the number of the piece of data, the transmission server divides the total data volume of the data to be transmitted by the number of the piece of data to obtain the unit data volume of each piece of data, and the transmission server divides the total data volume to be transmitted by the unit data volume to obtain a plurality of pieces of data with the same data volume.

For example, the transmission server obtains a total data volume of data to be transmitted, the total data volume is a, the number of the target memory is B, the transmission server determines that the number of the piece data is B, the total data volume to be transmitted is divided by the number of the piece data to obtain a unit data volume of each piece data as a/B, and the transmission server performs average fragmentation on the total data volume according to the unit data volume as a/B to obtain a plurality of piece data with the data volumes being a/B.

In this embodiment, the total data volume of data to be transmitted is acquired, and the number of target memories is taken as the number of pieces of data; determining a unit data amount of each slice data based on the number of the slice data and the total data amount; the data to be transmitted is fragmented through the unit data volume to obtain a plurality of fragment data, the number of the fragments at each time can be ensured to be the same, and the data volume of each obtained fragment data is the same, so that the transmission server can ensure the balanced transmission when the transmission server transmits the data by transmitting the fragment data with the same data volume, the subsequent isolation server can acquire the fragment data, the processing pressure of the isolation server is greatly reduced, and the requirement of load balance when the data is transmitted is met.

In one embodiment, the slicing the data to be transmitted to obtain a plurality of pieces of data includes: determining a preset data volume, and fragmenting data to be transmitted based on the preset data volume to obtain a plurality of pieces of data; wherein a data amount of at most one slice data among the plurality of slice data is smaller than the preset data amount.

Specifically, the transmission server determines a preset data volume based on the preset file, and fragments the data to be transmitted one by one based on the preset data volume until the remaining data volume of the remaining data to be transmitted is less than the preset data volume.

For example, the transmission server obtains a preset file, determines a preset data volume based on the preset file, performs a first time slicing on the data to be transmitted based on the preset data volume by the transmission server to obtain a first slice data and a first time residual data, compares the size of the first time residual data with the preset data volume, when the first residual data is larger than the preset data amount, the transmission server performs second fragmentation on the first residual data based on the preset data amount to obtain second fragmentation data and second residual data, performs the next iteration cycle, and taking the second residual data as the random first residual data for the next iteration, returning to the step of comparing the size of the first residual data with the preset data amount for continuous execution, stopping until the first residual data is less than or equal to the preset data amount, and acquiring a plurality of pieces of data obtained through iteration circulation.

In this embodiment, a preset data volume is determined, data to be transmitted is fragmented based on the preset data volume to obtain a plurality of pieces of data, and it can be ensured that the data volume of at most one piece of data is smaller than the preset data volume, thereby ensuring that the data volumes of the rest pieces of data are the same, ensuring balanced transmission when the server transmits data to the greatest extent, being beneficial to subsequent isolation servers, greatly reducing the processing pressure of the isolation servers, and realizing the requirement of load balance when transmitting data.

In one embodiment, the one-to-one correspondence between the fragment identifier and the storage address and establishment of an index relationship to obtain a hash table includes: carrying out hash processing on the fragment identification to obtain a mapping address corresponding to the fragment identification; and performing one-to-one association on each storage address and the fragment identifier mapping address, and storing the storage address into the associated mapping address to obtain the hash data table.

Specifically, the transmission server performs hash processing on the fragment identifier through a hash algorithm to obtain mapping addresses corresponding to the fragment identifier, associates each storage address with each mapping address corresponding to the fragment identifier one by one, establishes an index relationship between each storage address and each mapping address, and obtains a hash data table.

For example, the transmission server obtains a hash function, inputs each fragment identifier into the hash function to obtain a mapping address corresponding to the fragment identifier, and the transmission server associates each mapping address with each storage address in sequence according to the sequence of each mapping address, and stores the storage address into the associated mapping address to obtain a hash data table.

In this embodiment, the fragmentation identifier is subjected to hash processing to obtain a mapping address corresponding to the fragmentation identifier; the Hash data table is obtained by associating each storage address with the fragment identifier mapping address one by one and storing the storage address into the associated mapping address, so that the Hash data table and the fragment identifier of the isolation server can be used for acquiring each piece of data from the target memory, the subsequent isolation server can acquire each piece of data through acquiring each piece of data, the processing pressure of the isolation server is greatly reduced, and the requirement of load balance during data transmission is met.

In an embodiment, as shown in fig. 3, a method for transmitting data of a power grid monitoring system based on hash algorithm fragmentation and reassembly is provided, which is described by taking the method applied to the isolated server in fig. 1 as an example, and includes the following steps:

step S302, receiving a data transmission request, and analyzing the data transmission request to obtain a hash data table and a fragment identifier; the hash data table is obtained by fragmenting data to be transmitted to obtain a plurality of pieces of data, labeling each piece of data to obtain a fragmentation identifier, and establishing an index relationship between the fragmentation identifier and storage addresses respectively corresponding to a plurality of target storages.

Specifically, the isolation server receives a data transmission request, and analyzes the data transmission request to obtain a hash data table and a fragment identifier, where the hash data table is obtained by one-to-one correspondence between the fragment identifier and storage addresses corresponding to a plurality of target storages respectively and establishing an index, and the fragment identifier is obtained by performing labeling processing on a plurality of pieces of data obtained by fragmenting data to be transmitted based on the transmission server.

Step S304, based on the fragment identifier, finding the storage address corresponding to each fragment identifier from the hash data table, and based on the found storage address, obtaining the fragment data corresponding to the fragment identifier from each target storage.

Specifically, the isolation server queries, based on the fragment identifier obtained from the data transmission request, a storage address corresponding to each fragment identifier from mapping addresses in which a plurality of storage addresses are stored in the hash data table, and obtains, based on the found storage address, the piece data corresponding to the fragment identifier from each target storage.

Step S306, according to the sequence of the fragment identification corresponding to each piece of data, the plurality of pieces of data are recombined to obtain data to be transmitted, and the data to be transmitted is sent to the receiving server.
