All nodes and elements of the system are executed on a standard potentially switching elements.

The system works as follows.

In the information input system according to the transmission path of data sequentially received files updating data from objects sources of information.

All incoming files updating written in the buffer memory system (not shown).

Each file updating is accompanied by signs in the following codogram:

Code identifiers actualizationThe procedure code that needs to run with this entry (delete or modify)

After receiving the file actualization in the buffer memory system ID code updating input system 20 via the information input unit 1 is supplied to the inputs of registers 33-35, where and recorded clock pulse input 25 of the system and the procedure code entered from the entrance 22 to the information input of the register 7, which is inserted in the same clock pulse input 25. In the register 33 is filled in the service code source information register 34 - code flight number, and in the case of 35 - code of the corresponding index.

The contents of the actual file updating, including specific data relevant indicators, with an information input 21 system goes into register 6, which is inserted in the same clock pulse input 25.

With outputs 39 and 40 of the registers 33, 34 respectively codes flight number and the corresponding indicator comes on informational inputs 59 and 60 of the device 3, as well as information on the inputs 79 and 80 of unit 4, where they are received at the inputs of the decoders 50 and 70, respectively.

The decoder 50 decodes the input codes and prepares a circuit to the signal input 61, opening one of the elements 52 -54 I. To determine what lennosti place, the high potential received at one input element 52 I.

In parallel, the clock pulse input 25 of the system is fed to the input 61 of the block 3, which is delayed by element 56 during operation of the decoder 50, and then queries the state of the elements 52-54 I.

Given the fact that open on one input will be only element 52 And, through this element And the sync pulse arrives, firstly, to the input of the read fixed memory permanent storage device 51 that stores the ID code memory area, which includes code flight number and code of the corresponding index.

ID code memory area is read from the output 62 to the information input of the register 10.

Secondly, the same pulse is read from the output element 55 OR delayed by the delay element 57 at the time of reading the contents of a fixed cell ROM and then output 63 is supplied to the clock input of the register 10, locking it read the code.

Simultaneously with this code flight number and the corresponding indicator outputs 39, 40 registers 44, 34 through the inputs 79 and 80 of the block 3 are received at the inputs of the decoder 70.

The decoder 70 decodes the codes, throwing on one of its outputs a high potential.

For definiteness, suppose that a high potential is received at one input of ale and the NTA 73 I. The element 73 And will be opened on the same input, and thus will be prepared circuit signal input 81 unit 4 to the inputs of the memory block 71 and the element 75 OR.

ID code memory area belongs to the code flight number and the appropriate indicator from the output of the register 10 is supplied to the information input 45 block 2 and to one input of the comparator 43, the other input is from the output of the register 42 constantly applied identifier code memory area specific airline's service.

Simultaneously, the clock pulse from the output 63 of the block 3, the detainee element 58 on the recording time code in the register 10, exit 64 unit 3 is supplied to the clock input 44 of the comparator 43 block 2.

On this signal, the comparator 43 compares the input codes. If you compare the code has occurred, the output 46 of the comparator 43 unit 2 receives the impulse that comes on the installation unit 1 and registers 6, 7, returning to their original state.

If code flight number and the corresponding indicator included in the boundaries of the allocated memory, the comparator 43 unit 2 will record this fact by issuing a sync pulse at the output 47 of the block 2.

With the specified output clock pulse, first, available at the output 30 of the system as a signal of readiness of the system for use in update mode data. Second, e is from the same pulse is supplied to the clock input 81 of the device 4, where to this time open to one input of the element 73 I.

Input 81 clock pulse passes the element 73 And receives, firstly, to the input of the read fixed memory permanent storage device 71 that stores the base address of the memory zone server that belongs to the specified flight number and the corresponding index.

The code base address of the memory areas of the server that stores the data registration of the flight, read the information input of the register 11.

Secondly, the same pulse is read from the output element 75 OR delayed by the delay element 77 at the time of reading the contents of a fixed cell ROM and then output 83 is supplied to the clock input of the register 11, locking it read the code base address.

The code base address from the output of the register 11 is supplied to one data input of the adder 5, other information whose input is from the output register 41 35 block 1 is code of the corresponding index.

On the clock pulse from the output 84 of the block 4, the adder 5 adds to the base address code of the corresponding index, and the generated code recording address of the database server from the output of the adder 5 is supplied to the input 95 of the block 12, where he served on the information input of the counter 90.

The synchronizing pulse is output 84 unit 4 is fed to the input 96 of the block 12, where is delayed element 93 at the time of operation of the adder 5, and then the same pulse, first, is supplied to the clock input of the counter 90 and enters a code generated read address write database server, which output 99 of the block 12 is thrown on the address 28 the system output.

Secondly, the same clock pulse passes the element 92 OR delayed element 94 at the time of entering the code in the counter 90.

Then exit 100 block 12 the pulse available at the output 29 of the system as a timing signal is read at the input of the first interrupt server database.

On this signal, the server goes to the subroutine read the cell content of the database at the specified output 28 to address the issue of database records information on the input 23 of the system and recording it in the register, 8-synchronization pulse received from the server to the input 26. In parallel with the input 24 of the same system clock pulse input 26 from the database server in the register 9 is inserted ID value of the current index.

Thus, in the register 8 will be all the attributes to record the selected flight, and the register 6 by this time already all the attributes of the records from the file updated.

Codes from outputs of the registers 6 and 8 of the act on informational inputs 103 and 104 to which paratore 101 block 13, on the clock 105, the inlet of which a clock pulse input 26. This clock pulse is delayed by element 102 at the time of admission code register 8 and then supplied to the clock input of the comparator 101.

This sync pulse comparator 101 compares the input codes, and if the attributes of the indicators of the flight, in case 6, do not coincide with the attributes of performance of flight of the register 8, the output 106 of the comparator 101 unit 13, a signal occurs.

This signal is firstly fed to the counting input of the counter 16, fixing the number of scanned records from the database server.

Code number of scanned records from the output of the counter 16 is supplied to the information input unit 113 14, to another information input 114 which is the code number of indicators from the output of the register 9.

Secondly, the pulse from the output 106 of the block 13 is supplied to the clock input 115 of the block 14, where the delayed element 112 during operation of the counter 16, and then enters the clock input of the comparator 111, compares the number of scanned records with the number of indicators, related to that flight.

If the number of scanned records registered by the counter 16, is less than the number of indicators registered in the specified flight, at the output 116 of the comparator 111 unit 14 receives the impulse. This pulse through whod unit 12 and the element 91 OR passes at the counting input of the counter 90, increasing per unit consolidated base address of the recording server database, which is available at the output 28 of the system.

In addition, this pulse passes the element 92 OR delay element 94 at the time of actuation of the counter 90 and the newly issued through the output 29 of the system to the input of the first interrupt server database.

On this signal, the server returns to the routine of reading the cell content database on the newly formed address is issued on the information input 23 of the system and recording the contents of another cell of the database in the register 8 clock pulse coming from the server to the input 26.

Describes the process of reading the indices of the cells of the database and compare their contents with the contents of the first recording file updating will continue up until the comparator 101 unit 13 will not record the fact of the coincidence of the codes in the registers 6 and 8.

This fact is documented by the appearance of the pulse at the output 107 of the block 13, whence it is fed to the input 130 of the block 15, the information input 129 which receives the operation code that should be executed when updating data:

- to update the data records of the database

- delete the entire record of the database

- make a new entry in the database.

The operation code is decoded by the decoder 120, which opens one of the elements 121, 12, 123 I.

If the data in the database record should be updated, then the sync pulse input 130 passes elements 124 OR 121 And block 15 and then through the element 126 OR available at the output 31 of the system as a recording signal to a specified output 28 of the system to address the content of the register 6 from the output 27 of the system.

If the data should be excluded from the database records on this flight, the clock pulse input 131 passes elements 124 OR 122 And the block 15 and then available at the output 32 of the system as a signal to remove the entries for the specified output 28 of the system address.

If the block 12 will not fix compare the contents of registers 6 and 8 after viewing the attributes of records that, in case of equality codes of the counter 16 and the register 9, the comparator 111 of the block 14 to the clock input 115 at the output 117 will record the fact that the contents of register 6 is a new record to the database.

In this case, the clock pulse from the output 117 of the block 14, first, through the inlet 98 of the block 12 and the element 91 OR fed to the counting input of the counter, increasing the summary address entries per unit.

Additionally, this same pulse through the input unit 131 15 passes element 124 OR further element 123 And delay element 127 at the time of actuation of the counter 90 of the block 12 and then through the element 126 OR available at the output 31 of the system as a signal entry new entry in b is the memory data.

After the procedure updates the database record in all modes of refresh pulses from the outputs of the elements 121-123 And pass through the element 125 OR to the input of the delay element 128, where linger at the time of the update operation and then output 132 of the block 15 are issued for the installation inputs of all units and units of the system, and are issued at the output 33 of the system as the alarm system readiness for the next cycle of operation.

Thus, the introduction of new units will significantly improve the system performance by localizing address database records the IDs of the data sources and flights.
