Description

The invention relates to the field of computer technology, in particular, to a device for collecting and processing airborne data coming from several radar stations.

Due to the fact that radar viewing areas often overlap, information about the same airborne object can come simultaneously from several stations. Ideally, such marks of airborne objects should overlap one another. However, practically no coincidence is observed due to systematic and random errors in the measurement of coordinates of airborne objects, different location times, and also because of errors that occur when parallax is taken into account between the radar station points and the tertiary processing point on which the device for collecting and processing is installed air traffic data.

In this regard, the task of unambiguous identification of airborne objects arises with particular urgency, the data on which simultaneously come from various radars with overlapping viewing areas.

The first of the known devices 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 device is the impossibility of solving the problem of updating the data stored in its memory at the same time as solving the problem of delivering the contents of this data to users in real time.

Another device is known that contains data processing units, the information inputs of which are connected to the data reception and control units, and the outputs are connected to the first group of memory units, the central processor, the inputs of which are connected to the outputs of the memory units of the first group and data processing units, and the outputs are connected with the inputs of the memory blocks of the second group and data display blocks (2).

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

The disadvantage of this technical solution is its low speed, due to the fact that the identification of objects is carried out by first recording their coordinates in the database, followed by selecting the required data for processing, which inevitably leads to the inability to identify objects in real time.

The purpose of the invention is to increase the speed of the device by eliminating the procedures for pre-entering data of air objects in the database and then searching for their coordinates to solve the problem of identification of air objects.

The drawing shows information 146, first 147 and second 148 clock inputs, as well as information 149, first 150 and second 151 clock outputs.

All nodes and elements of the device are made on standard potential-pulse elements. The initial installation of the elements and components of the device to its original state to simplify the structural diagram of the device is not shown.

The device operates as follows.

During the airspace survey, from the radar stations of the survey to the information input of the unit 1 sequentially in time are received report codograms having the following data structure:

THE CODE THE CODE THE CODE THE CODE THE CODE Reporting Radar Number Air Object Number Airborne coordinates Characteristics of the air object Location time

This codogram from the input 11 of the device enters the information input of block 1, where it is entered by a synchronizing pulse from the input 12 of the device.

From the output 19 of block 1, the code combination corresponding to the radar number that sent this codogram arrives at the information input 30 of block 2, from where it is issued to the input of the decoder 21.

The decoder 21 decrypts the code combination and prepares the data transmission circuits from the input 31 and the synchronizing signal from the input 32, opening the elements of And group 26 and the element 24 And, respectively.

As a result of this, the complete radar report codogram from the output 20 of block 1 through the input 31 of block 2 and elements 26 AND of the group is fed to the information input of register 22.

In parallel, the synchronizing pulse from the input 12 of the device enters the input 32 of block 2, where it is delayed by element 28 for the duration of entering the codogram into block 1 and the operation of the decoder 21, and then polls the states of elements 24, 25 I.

Considering the fact that only element 24 will be open at one input and, having passed this element And, the synchronizing pulse arrives both at the synchronizing input of register 22, entering the contents of the input codogram into it, so through output 36 of block 2 it goes to input 51 of the block 3.

Thus, the codogram with the coordinates of the airborne object received from a particular radar will be recorded in register 22 of block 2, from where the content of the codogram through output 34 of block 2 is fed to the information input 71 of block 4.

In parallel with this, the synchronizing pulse of receiving the first codogram from the input 51 of block 3 goes to the direct input of the trigger 42 and sets it to a single state, in which the high potential from the direct output of the trigger 42 opens one element 43 And one input, the generator is connected to the other input timing pulses, the repetition period of which is selected taking into account the speed of movement of air objects, for example, in one clock period the air object can move a distance of 10 meters.

The clock pulses of the generator 41, passing element 43 And, are fed to the counting input of the counter 48, counting a given number of pulses, corresponding to the size of the temporary strobe, within which there can be only one mark from an air object. As soon as the counter 48 overflows, it is reset.

Thus, if during the gating interval after receipt of the codogram from the first radar there were no reports from other radars whose viewing areas overlap, then the overflow signal of counter 48 is, firstly, transmitted through element 47 OR to output 53 of block 3 and then goes through input 73 of block 4 to the direct input of flip-flop 61, setting it to a single state, in which flip-flop 61 opens a group of 63 AND elements, thereby connecting the output 34 of block 2 through elements 63 and groups and elements 66 OR groups to the information output of the device.

Secondly, the counter overflow pulse 48 passes the OR element 46 to the installation input of the trigger 42 and returns it to its original state, in which the low-potential trigger 42 closes the And element 43 from the direct output, thereby disconnecting the generator 41 from the counter 48 input.

In parallel with this process, the synchronizing pulse from the input 73 of block 4 passes the OR element 65, is delayed by the element 67 for the duration of the trigger 61 and then, firstly, from the output 76 it is issued both to the output 16 of the device as a control signal for issuing a codegram to users, and to the input 90 of block 5 to start the procedure for documenting the data of the air situation, from where it is fed to one of the inputs of elements 84, 85 I.

However, only one element And will be open at one input, since one of its inputs is supplied with a high potential from the inverse output of trigger 83, which is in the initial state.

As a result, a synchronizing pulse from input 90 passes through the And element 85, and enters the input of a fixed memory cell in ROM 81, where the reference address of the buffer zone of the server’s memory reserved for storing air data records is stored.

The same clock pulse from the output of element 85 is delayed by element 87 for the duration of reading the code from ROM 81, and, firstly, it goes to the clock input of register 82, entering the reference address of the record into it.

Secondly, the same pulse is applied to the single input of trigger 83 and sets it to a single state, in which element 85 And will be closed, and element 84 And will be open. This will prepare the circuit for the passage of the next clock pulse from input 90.

And, finally, thirdly, the pulse from the output of the delay element 87 passes through the OR element 86, is again delayed by the element 88 for the time the address code is entered into the register 82, and from the output 92 of the block 5 it enters the input 147 of the block 6.

The write address code from the output 91 of block 5 is issued to the input 146 of block 6 and then to one input of the adder 132, to the other input of which is connected the output of the counter 130, also connected to one input of the comparator 131, the “zero code” is constantly applied to the other input.

The clock pulse from input 147, firstly, immediately through the OR element 135, is fed to the clock input of the adder 132, which sums the reference address code from input 146 with the zero code of the counter 130, which is in its original state by this time and gives out code address entry entry elements 134 And groups.

Secondly, the same pulse passes through the OR element 138 and enters the direct input of the trigger 133, setting the latter to a single state, in which the high potential from the direct output opens the And elements of the 134 group on the other input, thereby connecting the output of the adder 132 to the output 149 As a result, the reference address of the record is issued to the address 15 output of the device.

Thirdly, the synchronizing pulse from input 147 is delayed by element 140 for the duration of the formation of the final code at address 15 of the output device and through output 150 is output to output 17 of the device as a write control signal.

This signal is input to the first channel of the database server interrupt, through which the server goes to the subroutine for recording the contents of block 4 from the output 14 of the device to the database at the address generated at the output 15 of the device.

In addition, the pulse from the output of the delay element 140 enters the counting input of the counter 130, fixing the first record, and also, after the delay by the element 145 for the time of writing data to the system database, this pulse passes the input of the OR element 139, setting the trigger 139 to its original state. Returning to its initial state, the trigger 139 closes the elements 134 AND groups on one input and, thereby, disconnects the output of the adder 132 from the address 15 output of the device.

If, after receiving a report from the first radar, another radar is transmitted to the input 11 of the device, the field of view of which overlaps with the field of view of the first radar, then in this case, after writing the codogram to block 1, the decoder 21 will open the elements 27 And groups and element 25 And, providing entry of the input codogram into register 23.

In this case, the synchronizing pulse from the input 32 of the block 2 passes through another element 25 And, and from the output 37 of the block 2 goes to the input 52 of the block 3, from where it is fed to one of the inputs of the elements 44 and 45 And, controlled by the state of the trigger 42.

Two situations are possible here.

The first situation arises if the codogram of the second radar report belongs to the same airborne object whose coordinates were recorded by the first radar station.

In this case, the trigger 42 will be in a single state and the element 44 will be open. The clock pulse from input 52 will pass through the element 44 AND, then 47 OR, and from the output 53 of block 3 and then goes through the input 73 of block 4 to the direct input of the trigger 61, setting it to a single state, in which the trigger 61 opens a group of 63 AND elements, connecting thereby, the output 34 of block 2 through the elements 63 AND groups and elements 66 OR groups to the information output of the device.

Secondly, the pulse from the output of the element 44 AND passes the element 46 OR to the installation input of the trigger 42 and returns it to its original state, in which the trigger 42 with a low potential from the direct output closes the element 43 And, thereby disconnecting the generator 41 from the counter input 48.

In parallel with this process, the synchronizing pulse from the input 73 of block 4 passes the OR element 65, is delayed by the element 67 for the duration of the trigger 61 and then, firstly, from the output 76 it is issued both to the output 16 of the device as a control signal for issuing a codegram to users, and to the input 90 of block 5 to start the procedure for documenting the data of the air situation, from where it is fed to one of the inputs of elements 84, 85 I.

The second situation arises if the second radar detects the mark of another airborne object.

In this case, the reception time of the codogram of the second radar exceeds the time gating determined by the counter 48 of block 3, and therefore the trigger 42 of block 3 will be in the initial state, in which element 45 I will be opened with high potential from the inverted output of trigger 42.

As a result of this, the synchronizing pulse from input 52 will pass through the element 45 And, and from the output 54 of block 3 will go to the input 74 of block 4 and then to the direct input of the trigger 62, setting it to a single state, in which the trigger 62 opens a group of 64 And elements, connecting thereby, the output 35 of block 2 through the elements 64 AND groups and elements 66 OR groups to the information output 14 of the device.

In parallel with this process, the synchronizing pulse from the input 74 of block 4 passes through the OR element 65, is delayed by the element 67 for the duration of the trigger 61 and then, firstly, from the output 76 it is issued both to the output 16 of the device as a control signal for issuing a codogram to users, and to the input 90 of block 5 to start the procedure for documenting the data of the air situation, from where it is fed to one of the inputs of elements 84, 85 I.

In addition, the synchronizing pulse from the output of the element 67 of the delay unit 4 is again delayed by the element 68 at the time of issuing and documenting the air situation data, and then it is issued to the installation inputs of the triggers 61, 62 of the unit 4 and from the output 77 of the unit 4 to the installation input 33 of the unit 2.

If necessary, the issuance of documented data of the air situation at the input 13 of the device receives a data request signal, which is fed to the input 148 of block 6 and then, firstly, through the element 138 OR enters the single input of the trigger 133, setting it to a single state, at which high potential from a direct output opens the elements 134 And groups on another input, thereby connecting the output of the adder 132 to the output 149.

As a result of this, the address of the last record stored in the adder 132 from the output 149 is issued to the address 15 output of the device.

Secondly, the synchronizing pulse from the input 148 is delayed by the element 143 for the duration of the trigger 133 and through the element 137 OR is issued to the output 18 as a control signal for reading data. From the output 18 of the device, the signal goes to the input of the second channel of the database server interrupt.

By this signal, the server switches to a subroutine for reading the contents of the database cell at the address indicated on output 15, and issuing the first record of air traffic data.

In addition, the synchronizing pulse from the output of the OR element 137 is delayed by the 144 element for the duration of reading data from the database, and, firstly, through the OR element 136 it is supplied to the installation input of the adder 132, resetting it to its original state.

Secondly, this pulse is fed to the subtracting input of the reverse counter 130, reducing its readings by one.

Thirdly, this pulse is delayed by the element 141 for the response time of the reversible counter 130 and is supplied to the synchronizing input of the comparator 131.

The comparator 131 compares the readings of the reverse counter 130 with a zero code supplied to its other input, and while the readings of the counter 130 are greater than the zero code, a signal is generated at the output A of the comparator 131, which, firstly, passes through the OR element 135 to the synchronizing input of the adder 132, which, by this signal, sums the code of the reference address from input 146 with a reading of the counter counter 130 reduced by one and gives the final address to address 15 of the device output.

Secondly, the same pulse is delayed by the delay element 142 for the operation time of the adder 132, the OR element 137 passes, and from the output 151 is output 18 as the next data reading control signal.

By this signal, the server again switches to the subroutine for reading the contents of the database cell at the address indicated on output 15, and issuing the next database record to the display and printing facilities (not shown in the drawing).

In addition, the synchronizing pulse from the output of the OR element 137 is again delayed by the 144 element for the duration of reading data from the database, and, firstly, again through the OR element 136 it is supplied to the installation input of the adder 132, resetting it to its original state. Secondly, it again enters the subtracting input of the reverse counter 130, reducing its readings by one.

Thirdly, it is delayed by element 141 for the duration of the operation of the reversible counter 130 and enters the synchronizing input of the comparator 131.

The comparator 131 again compares the readings of the reversing counter 130 with a zero code supplied to its other input, and while the readings of the counter 130 are greater than the zero code, a signal is generated at the output A of the comparator 121, which, firstly, passes through the OR element 135 to the clock input the adder 132, which on this signal sums the code of the reference address from input 146 with a reduced by one reading of the reverse counter 130 and provides the final address to the address 15 output of the device.

The described airborne data reading process continues until the comparator 131 records the fact that the readings of the reversible counter 130 are equal to zero, indicating that all lines of the airborne data record are issued to the display and printing means.

This fact will be confirmed by the issuance of a pulse to the output of the comparator 131, which is supplied to the installation inputs of the reversible counter 130, the adder 132 and trigger 133.

Thus, the introduction of new nodes and blocks has significantly improved the speed of the device by eliminating the preliminary procedures for entering data of air objects into the database and then searching for their coordinates to solve the problem of identifying air objects.
