Description

The invention relates to computer technology, in particular, to the information retrieval system of the portal of the all-Russian state information center when performing public procurement.

The information retrieval system of the portal of the All-Russian State Information Center for public procurement is designed to implement the functions of entering, storing, organizing and retrieving information related to the provision of information services to suppliers.

The system should provide suppliers with the opportunity to operate with information on government orders for goods and prices for them, allow them to download information from external sources, classify it in a form convenient for subsequent analysis, and then make various samples for conducting market research, searching for partners, etc. P.

When solving the problems of organizing data storage, the system should provide the following functions: maintaining the classifier system up to date, storing stored information on classifiers, storing information about organizations and personalities, storing information about goods, storing information about offers / requests with prices, etc. P.

The peculiarity of the technical task posed is the need to organize such a selection of system data that would dramatically reduce the time spent by users of the system in searching and presenting the required data.

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 system is the impossibility of solving the problem of updating data stored in memory in the form of relevant documents at the same time as solving the problem of delivering the contents of these documents to users in real time.

Another system is known, comprising a central processing unit, the inputs of which are connected to the memory blocks and to the data preparation and input units, and the outputs are connected to the corresponding memory blocks, the data processing unit, the information inputs of which are connected to the outputs of the corresponding memory blocks, the synchronizing inputs are connected to control outputs of the central processing unit, and the output of the block is the information output of the system (2).

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

Its disadvantage lies in the low speed of the system, due to the fact that the selection of information fund data is carried out by searching for information throughout the database, which, with huge amounts of data from the information fund, inevitably leads to unreasonably large time spent on obtaining the required information.

The purpose of the invention is to improve system performance by eliminating the search for information fund data across the entire database and localizing information retrieval only by identifiers of catalogs of goods and services.

This goal is achieved by the fact that in a known system containing a module for receiving requests from suppliers of public services, the information input of which is the first information input of the system, and the synchronizing input is the first synchronizing input of the system, the module for receiving records of public procurement proposals from the system server database, the information input of which is the second information input of the system, synchronizing the input of the module for receiving records of state proposals for the purchase from the system server database is the second synchronizing system input, the module for generating the read addresses of the system server database, the first and second information outputs of which are the first and second information outputs of the system, a module for selecting base addresses of public procurement data catalogs is introduced, the information input of which is connected to the first information output of the module for receiving records of public procurement proposals from the system server database, synchronizing the input of the village module the section of the base addresses of the public procurement data catalogs is connected to the first synchronizing input of the system, the information output of the selection module of the base addresses of public procurement data catalogs is connected to the first information input of the module for generating the read addresses of the system server database, the first and second synchronizing inputs of which are connected to the first and second synchronizing outputs of the module for selecting base addresses of public procurement data catalogs, while the third synchronizing you the progress of the selection module for the base addresses of the public procurement data catalogs is the synchronizing output of the system, the module for the selection of the base addresses of the subdirectories of public procurement data, the information input of which is connected to the second information output of the module for receiving records of public procurement proposals from the system server database, synchronizing the input of the base addresses selection module subdirectories of public procurement data connected to the first synchronizing input of the system, and the first information the first output of the module for selecting the base addresses of the subdirectories of public procurement data is connected to the second information input of the module for generating the read addresses of the database of the server of the system, the module for identifying the length of the subdirectory of public procurement data, the information input of which is connected to the second information output of the module for selecting the base addresses of subdirectories of public procurement, the first the synchronizing output of the module for identifying the length of the subdirectory of public procurement data is connected to the input to the system server database read address generation module and to the clock input of the public procurement data directory base address selection module, and the second synchronization output of the public procurement data subdirectory identification module is connected to the third synchronization input of the system server database database read address generation module;

We will consider the operation of the system by the example of fulfilling a supplier’s request for information from the public procurement information fund about the minimum price of goods at which public procurement is carried out on electronic trading floors.

All goods and services of the information fund of the All-Russian Information Center are divided into catalogs by groups, each of which has a separate subdirectory for a particular type of product.

For example, a catalog such as “Vegetable Products” can be attributed to the number of catalogs by product group, inside which subdirectories by type of vegetable product, for example, potatoes, carrots, beets, etc. will be presented.

To solve this problem, a request is generated at the supplier’s workplace, in which the catalog of products of interest to him and a subdirectory, for example, “Potato”, are indicated. Then the supplier presses the "Issue" button.

The request codogram has the following structure:

Type of product catalog Type of product subdirectory Product Catalog Code Subdirectory code for selected products

This request arrives at the information input 10 of the system and a synchronizing pulse from input 12, the request codogram is entered in register 1.

From the output of 21 register 1, the catalog code through the information input 37 of module 2 is fed to the input of the decoder 25. The decoder 25 determines the sign of the catalog, giving out one of its outputs a high potential.

For definiteness, we assume that a high potential is received at one input of element 30 I. At the same time, a synchronizing pulse from input 12 of the system enters input 38 of module 2 and is then delayed by element 32 for the duration of decryptor 25 operation, and then it polls the states of elements 28-30 AND.

Considering the fact that only the And element 30 will be open at one input, then, having passed this And element, the clock pulse arrives, firstly, at the read input of a fixed memory cell of the permanent storage device 26.

A fixed memory location stores the base address of the selected directory in the system server database.

Secondly, the same read pulse is delayed by the delay element 33 for the duration of reading the contents of a fixed ROM cell and then goes to the synchronizing input of the register 27, fixing in it the code of the address of the memory zone coming from the output of the ROM 26.

In parallel, the same clock is delayed by element 34 while the base address code is entered into register 27, and then output to output 41 as a synchronization pulse, indicating that the base directory address code from register 27 is ready for output 40.

From the second output 22 of register 1, the subdirectory code enters through the information input 56 of module 3 to the input of the decoder 46. The decoder 46 decodes the indicator code of the indicator, giving high potential to one of its outputs.

For definiteness, we assume that a high potential is received at one input of element 55 I. At the same time, a synchronizing pulse from input 12 of the system goes to input 57 of module 3, where it is delayed by element 50 for the duration of operation of decoder 46, and then polls the states of elements 53-55 AND.

Considering the fact that only the And element 55 will be open at one input, then, after passing through this And element, the clock pulse arrives, firstly, at the read input of a fixed memory cell of the permanent storage device 47, where the address of the memory zone of the subdirectory in the database server is stored system.

Secondly, the same read pulse is delayed by the delay element 51 for the duration of reading the contents of the fixed cell ROM 51 and then arrives at the clock input of the register 48, fixing in it the contents of the memory cell ROM 47.

The structure of the read code from the fixed cell ROM 47 in the register 48 consists of two parts and has the following form:

The code The code start address of the subdirectory in the server database long (number of positions) of the subdirectory

The base address code of the selected directory from the output 59 of module 3 is fed to the information input 76 of module 5 and then to one input of the adder 72, the other information input of which from the input 75 of module 5 receives the code of the starting address of the subdirectory.

According to the synchronizing pulse coming from the input 78 of module 5, the adder 72 summarizes the indicated codes and gives the total address to the information input of the summing counter 73, where it is entered by the synchronizing pulse from the input 79 of module 5.

At the same time, the code of the length of the subdirectory from the other output of the register 48 of module 3 is fed to the information input of the subtracting counter 49 and is entered into it by a synchronizing pulse from the output of the delay element 52. Element 52 delayed this pulse by the time the code was written to register 48.

In the process of entering the total address code into the counter 73 of module 5 and the length of the subdirectory in the counter 49 of module 3, the synchronizing pulse from the output of the delay element 35 of module 2 through the element 31 OR is fed to the input of the element 36, where it is delayed by the time the codes were entered into the counters 73 and 49 respectively. Then, from the output 43 of module 2, this pulse is output to the output 16 of the system, from where it arrives at the input of the first channel of the server interrupt.

With the arrival of this impulse, the database server of the system switches to the subroutine for polling the contents of the server database cell, the address of which is generated at the output of the system 17. The server reads the contents of the cell at the specified address and through input 11, according to the synchronizing pulse received at input 13, enters it into register 6.

The structure of the codogram in register 6 will have the following form:

THE CODE THE CODE THE CODE THE CODE product names unit prices production quantities of products for sale state order attributes

From the output 23 of register 6, the entire codogram is fed to the information input 101 of module 8 and then to the information input of register 99, and the part of the codogram containing the unit price code is fed to input 108 of the comparator 100.

At the same time, the synchronizing pulse from the input 13 of the system passes to the input 92 of the module 7, where it is delayed by the element 89 while the codogram is being recorded in register 6, and then it goes to one input of the 86 element, open at the other input with a high potential from the inverse output of the trigger 84.

The trigger 84 is in the initial state, therefore, the synchronizing pulse from the output of the And 86 element passes the OR element 88 and through the output 96 it goes to the synchronizing input 102 of module 8 and then to the synchronizing input of register 99, entering the encoding from register 6 into register 99.

In addition, from the output of element 86 And the same clock pulse is delayed by element 90 for the time the codogram is entered in register 99 of module 8, and, firstly, it goes to the direct input of trigger 84, setting it to a single state, in which trigger 84 blocks the pulse path through the element 86 AND prepares the pulse path through the element 85 AND, and secondly, it passes through the element 87 OR and then through the output 97 as to the installation input 19 of the register 6, resetting it to its original state, and through input 67 and output 70 mod A 4 to the count input 58 of the module 3 and further to the subtracting input of the counter 49 to decrease its code reading unit.

The counter reading code 49 from the output 60 of the module 3 through the input 66 of the module 4 is fed to the input of the decoder 61, which implements the following logic.

If there is a code equal to zero at the input of the decoder 61, then a low potential is generated at the output of the decoder 61, and if any other code value other than zero is recorded at the input of the decoder 61, then a high potential is generated at its output.

Given that the readings of the counter 49 of module 3 at this point in time are reduced by only one, then the decoder 70 produces a high potential, which opens the element 64 I.

In parallel, the pulse from the input 67 of the module 4 is delayed by the delay element 65 for the response time of the subtracting counter 49 of the module 3 and then goes to the input of the element 64 I.

From the output of the element 64 And the pulse through the output 68 passes to the counting input of module 5 and then to the counting input of the totalizing counter 73, and to the input 39 of module 2.

Counter 73, adding a unit to its readings, forms the next read address of the memory cell of the system server database.

From the input 39 of module 2, this synchronizing pulse passes through the element 31 OR, the delay element 36, delaying the pulse for the duration of the counter 73, and the output 43 of module 2 to the output 16 of the system, from where it is fed to the input of the first channel of the server interrupt.

With the arrival of this impulse, the database server of the system again switches to the subroutine for polling the contents of the server database cell, the address of which is generated at the output 17 of the system. The server reads the contents of the cell at the new address and through input 11, according to the synchronizing pulse received at input 13, registers it again in register 6.

In contrast to the first case, the synchronizing pulse from input 92 after delay by element 89 passes to output 97 of module 7 not through element 86 AND, but through element 85 AND, and immediately goes to synchronizing input 103 of module 8 and then comparator 100. Comparator 100 compares price codes of the previous record, which is stored in register 99, with the code of the newly received record from register 6.

If the price code of the newly received register entry 6 is greater than or equal to the price code located in the register 99 of module 8, then the comparator 100 generates a signal at the output 104, which passes through the input 93 of the module 7 and then the element 87 OR to the output 98, from where - first, it enters the installation input of register 6, returning it to its original state.

Secondly, it enters the input 67 of module 4, ensuring the formation of the address of the next memory cell of the server database and its reading in the manner described above.

If the price code of the newly received register 6 is less than the price code stored in the register 99 of module 8, then the comparator 100 generates a signal at the output 105, where it, having passed the input 94 of the module 7, firstly, through the OR element 88 and the output 96 immediately enters the synchronization input of register 99, copying the contents of register 6 into it, and, secondly, it is delayed by element 91 while the code of the new record is entered into register 6, and then through the OR element 87 and output 98 again resets register 6 to initial state and enters the input 67 of module 4, restarting the second mechanism for generating the address of the next memory cell of the server database and its reading.

The described process continues until the readings of counter 49 of module 3 are equal to zero, which indicates that the entire subdirectory of proposals for government procurement of products has been reviewed.

The moment of zero readings of the counter 49 will be fixed by the decoder 61 of module 4, which forms a low potential at its output. This potential is inverted by an inverter 62, which opens the element 63 AND on one input, to the other input of which a clock pulse from the input 67 is delayed by the delay element 65.

The clock pulse passes to the output of the element 63 AND, and then through the output 69 of the module 4 it goes, firstly, to the synchronizing input 81 of the module 5 and then to one input of the elements And 74 of the group, providing a codogram from output 18 with a minimum price for the goods from Register 99 of module 5.

Secondly, the clock pulse arrives at the installation inputs of the adder 72 and the counter 73, resetting them to their original state.

From outputs 17 and 18 of the system, a codogram with a minimum price of goods is issued to the supplier’s workplace.

Thus, the introduction of new devices and units and new constructive connections made it possible to significantly increase the system’s speed by eliminating data search across the entire database and localizing the search only at the reference addresses of catalogs and subdirectories of goods and services.
