Description

The utility model relates to computing, in particular, to an automated telecommunications data network in the manufacture, processing and control of passport and visa documents (LDPE) of a new generation.

The state system for the manufacture, processing and control of passport and visa documents (LDPE) of the new generation is a combination of the following segments:

- automated departmental subsystems geographically distributed throughout the country, providing support for the application processes of a specific Department of Departmental Segments (AF);

- a distributed center for technological support of applied processes (for the manufacture, design and control of LDPE) and support for the functioning of the hardware and software of the system - integration segments (IS);

- data transmission networks based on a secure telecommunication environment - data transmission (SPD).

The unified telecommunication infrastructure of the data transmission network includes two sectors: the domestic one - the same for all departmental segments, including units of the Russian Ministry of Foreign Affairs in the territory of the Russian Federation, and the external one - providing information exchange between the Russian Ministry of Foreign Affairs and consular missions.

A single telecommunication network infrastructure provides the system components, as well as external systems, with electronic messaging services, isolating these components from the transport environment and specific transport protocols, while ensuring the necessary level of information security.

The following requirements are imposed on data transmission networks of this purpose:

- the data transmission network should be based on the principles of creating secure superimposed telecommunication networks with centralized management;

- The structure of the data transmission network must be consistent with the system architecture.

- the data transmission network should include means for providing remote telecommunication authorized access to the System’s resources through wired and radio channels, including using departmental telecommunication resources, using cryptographic information protection on communication channels.

In accordance with the concept of NGN (next generation network), a three-level structure of the data transmission network is shown in FIG.

The transport layer provides switching and transparent transmission of information. Construction of the transport level on the basis of modern package technologies providing guaranteed quality of information transfer. These technologies currently include IP / MPLS and ATM.

The transport layer consists of two sublevels: the base (network core) and access.

The basic sublevel is a high-performance network core that provides transport services between objects. This level is created with the aim of high-speed packet transmission between nodes, making maximum use of bandwidth.

Access Level - a system that provides access to network resources to network users.

The level of control of switching and transmission of information - performs the functions of managing connections and flows, processing information of alarm systems, routing connections, access control, etc.

The service control layer performs the functions of managing the logic of services and applications. This level allows you to implement the specifics of services, regardless of the type of transport medium and access method. With this approach, the data transmission network is invariant to data transmission protocols, architectural features of the core networks and is standardized at the equipment level of access nodes, federal, regional and territorial levels.

The basis of the operator’s transport network should be a universal transport network that implements the functions

transport layer and the level of control switching, routing and transmission.

It is proposed to build a transport network of data transfer of the system for the production, processing and control of passport and visa documents (LDPE) of a new generation in the form of a two-level hierarchical structure consisting of trunk and regional levels (see Fig. 6).

The backbone transit level, consisting of backbone transit nodes (MTUs) located in each federal district, interconnected by broadband digital channels (paths) on the principle of “each with each” with full reservation of each direction by organizing channels along geographically separated routes. The backbone layer is designed to provide skipping, switching and routing of high-speed graphics.

The regional level, consisting of terminal (access nodes - UD) and terminal - transit nodes (UKT - concentration graph nodes), intended for concentration / distribution of the graph from / to the UD and entry to the main transit level. Each UKT is connected by digital channels with two (its own and adjacent) MTU along separated paths.

This makes it necessary to solve the problem of the interaction of all these objects, both when receiving information from information sources to the network input, and when transferring data from the system database at the request of objects - data recipients.

Known systems that could be used to solve the problem (1, 2).

The first of the known systems contains data reception and storage units connected to control and data processing units, search and selection units connected to data storage and display units, the synchronizing inputs of which are connected to the outputs of the control unit (1).

A significant drawback of this technical solution is the impossibility of solving the problem of converting data whose formats change in real time.

Another system is known that contains data reception and output registers connected to a message processing unit, a central processor and memory units, a data switching unit, the inputs of which are connected to the memory units and the central processor, and the outputs are system outputs (2).

The last of the above technical solutions is closest to the described.

Its disadvantage is that updating the data of documents provided to customers and stored in the first and second memory blocks cannot be performed in real time on transactions received from information sources. This problem in this system is solved by using manual procedures for updating documents from data received from remote sources, converting them into appropriate data formats and then loading them into the first and second memory blocks.

For the duration of these procedures, customer access to relevant documents is blocked, which leads to a sharp decrease in the speed of the customer service system in real time.

The purpose of the invention is to increase the system performance by eliminating the time spent on converting data formats when receiving messages from information source objects and issuing answers - inquiries to user object requests.

This goal is achieved by the fact that in the known system containing the first and second registers, the inputs of which are the first and second information inputs of the system, respectively, and the first outputs are the first and second information outputs of the system, respectively, the third register, one information input of which is the third information input system, another information input is connected to the second output of the second register, and the synchronizing input of the third register is the first synchronizing input of the system, b ok data switching, the information inputs of which are connected to the corresponding outputs of the third register, the synchronization input is connected to the first synchronizing input of the system, and the information outputs are information outputs of the system group, the first and second memory blocks, the outputs of which are connected to the information inputs of the fourth and fifth registers, respectively the outputs of which are the third and fourth outputs of the system, respectively, the first decoder is introduced, the input of which is connected to the second output of the first egistra, block for determining the input data format, information inputs of the group of which are connected to the corresponding outputs of the first decoder, the synchronizing input is the second synchronizing input of the system, the first output is connected to the synchronizing input of the first register, the second output is connected to the synchronizing input of the fourth register, the third output is

The drawing also shows the information inputs 96, 97, the synchronizing input 98, as well as the installation 99 and information outputs 100-102 groups.

All nodes and elements of the system are made on standard potential-impulse elements.

The system operates as follows.

The information input 15 of the system along the data transmission path consistently receives messages (codograms) from objects - sources of information. Codograms contain indicative and informational parts

Feature part Information part ID of the data source object The content of the message, reflecting the information of the formed questionnaires with the identification data of citizens for receiving passport and visa documents of a new generation

The characteristic part of the message contains the identifier of the source object of the information that sent the codogram, and the information part contains information reflecting the personal data of citizens.

The codogram code from input 15 enters the information input of register 1, and the synchronizing pulse accompanying the codogram code from the system input 19 through input 41 of block 8 is fed to one input of element 32 AND, the other input of which is currently open at high potential, issued through input 42 from the inverse output of the trigger 60, which is in the initial state, through the output 78 of block 9.

The synchronizing pulse from input 41 immediately passes through element 32 And to the output 46 of block 8 and then goes to the synchronizing input of register 1, bringing the contents of the codogram from input 15 into it.

From one output of register 1, the content part of the codogram is sent to the output 21 of the system, and from the other output, the identifier of the source that sent the codogram is given to the input of the decoder 6, which decrypts the code of the identifier and gives one of its outputs a high potential coming to the corresponding input of the block 8 (for definiteness, we assume that this is input 43).

The high potential from the input 43 opens one input of the 34 And element, the other input of which receives a pulse from the output of the 33 And, through which passes a synchronizing pulse, delayed by the element 30 for the time the code is entered in register 1 and the decoder 6 is triggered.

In addition, the synchronizing pulse from the input 41 of block 8, passing through the element 32, in addition to entering the input of the delay element 30 immediately goes to the direct input of the trigger 31, setting it to a single state and thereby opening the element 33 I.

From the output of element 34 And the synchronizing pulse, firstly, through the output 51 of block 8 is issued to the read input of a fixed cell in memory of block 10, where the “data format template” is stored, which describes the structure of the message codogram in which the specified information source transmits data input database of the corresponding segment of the system.

The contents of a fixed cell are read into the information input of register 4.

Secondly, the same synchronizing pulse passes through the OR element 37 and is delayed by the delay element 38 while reading the contents of the fixed cell of the ROM 10 and then from the output 47 of the block 8 it goes to the synchronizing input of the register 4, recording in it a description of the data format template, in the structure of which object - a source of information sent a codogram entered in register 1.

Thirdly, the same synchronizing pulse after delay by element 39 for the time information is entered in register 4, is output 48 of block 8 and then through system output 28 to the database server interrupt input (not shown), according to which the database server reads the full content of the message codogram from the information output 21 of register 1 and the content of the data format template from the information output 23 of register 4 and launches the database update program in accordance with the received transaction.

In parallel with this, the same clock pulse from the output of the delay element 39 is delayed by the element 40 during the polling of registers 1 and 4, and then goes to the installation input of the trigger 31, and from the output 49 of block 8 to the installation inputs of the registers 1, 4, preparing the system for receive the next message.

Thus, regardless of the data format the information source object works in, the database server always receives not only the codogram of the sent message, but a description of this format, which allows the database server to keep the population register database up to date in real time time.

As noted above, objects that are users of the system, in particular the passport and visa departments of various segments of the system, also work with data, the presentation format of which may be different from the data format adopted in the system. Despite this, the proposed technical solution successfully solves the problem of issuing data from databases of various segments at the request of user objects of the system.

Requests from recipient objects in the form of message codograms are sequentially received through the system input 16 to the information input of register 2, and the synchronizing pulse accompanying the receipt of the request codogram code from the system input 20 through the input 72 of the device 9 goes to one input of the And element 61, the other input of which at a given time, it must be opened with high potential from the inverse output of the trigger 31, which is in the initial state, issued from the output 50 of block 8 through the input 71 of block 9.

The structure of the codogram - a request for help from the database of the corresponding system object, sent by objects - data recipients, has the following form:

Feature part Information part Identifier of the object - data recipient Request Code

The clock pulse from input 72 immediately passes through element 61 And to the output 77 of block 9 and then goes to the clock input of register 2, entering the contents of the codogram from input 16 into it.

From one output of register 1, a request code is issued to the output 22 of the system, and from another output, the identifier of the object of the data recipient is issued to the input of the decoder 7. The decoder 7 decodes the identifier code and gives one of its outputs a high potential, which arrives at the corresponding input of block 9 ( for definiteness, we assume that this is input 75).

The high potential from the input 75 opens one input of the 64 I element, the other input of which receives a pulse from the output of the 62 And element, through which a synchronizing pulse is delayed by the element 67 while the code is entered in register 2 and the decoder 7 is triggered.

In addition, the synchronizing pulse from the input 72 of block 9, passing through the element 61 AND, in addition to entering the input of the delay element 67, immediately enters the direct input of the trigger 60, setting it to a single state and thereby opening the element 62 AND, preparing the passage chain pulse from the output of the delay element 67.

From the output of element 64 AND, a synchronizing pulse, firstly, through the output 80 of block 9 is issued to the read input of a fixed memory cell of block 11, where the “data format template” is stored, which describes the structure of the message encoding in which the specified information receiving object receives data from the database of the state population register. The contents of a fixed cell are read into the information input of register 5.

Secondly, the same synchronizing pulse passes through the OR element 66 and is delayed by the delay element 68 for the duration of reading the contents of the fixed cell of the ROM 11 and then from the output 82 of the block 9 is fed to the synchronizing input of the register 4, fixing the description of the data format template in it.

Thirdly, the same synchronizing pulse after the delay by the element 69 for the time the information is entered in the register 4, goes to the output 83 of the block 9 and then through the output 29 of the system to another input of the database server interrupt (not shown), according to which the database server reads the content of the request codogram from the information output 22 of the register 2 and the content of the data format template from the information output 24 of the register 5 and starts the program for preparing and issuing a certificate in accordance with the accepted request.

The help content in the data presentation format specified by the recipient object, the database server issues to the input 17 of the system, from where it goes to one input of register 3, the other input of which from the corresponding output of register 2 receives the identifier code of the object that sent the request. According to the server synchronizing pulse coming through the system input 18 to the synchronizing input of register 3, the input codes are entered into register 3.

As a result, the following data structure will be generated in register 3.

Feature part Information part Recipient Object Identifier Code Request response code

The code of the feature part of register 3 through the input 96 of block 12 is fed to the input of the decoder 90, which opens one of the elements 91-93 AND of the corresponding group (for definiteness, we assume that these are elements 91 AND of the group.

In parallel, the synchronizing pulse of the database server from input 18 enters through input 98 of block 12 to the input of element 94, where it is delayed by the time the codes are entered in register 3 and the decoder 90 is activated, and then it goes to the inputs of elements 91 AND of the group, rewriting the content of the response for a request to the data transmission channel to the user object through the output 102 of block 12 to the output 27 of the system.

In addition, the synchronizing pulse delayed by the element 95 for the duration of the response to the request, from the output 99 of the block 12 passes to the installation inputs of the registers 2, 3, 5, returning them to their original state and preparing the system for a new cycle of work.

In addition, the same pulse from the output 99 of the block 12 through the input 73 of the block 9 is supplied to the installation input of the trigger 60, also returning it to its original state.

Thus, the introduction of new nodes and blocks and new constructive connections made it possible to significantly increase the system performance by eliminating the time spent on preliminary transformations of data formats when receiving messages from information source objects and issuing help answers to requests from data recipient objects.
