FIG.  2  It contains a node 73 interface (communication interface with a source of information), the generator 74 clock pulses and node 75 synchronization.  As an additional unit 67 of comparison, any device that generates a signal Equals when equal equal multi-digit numbers arrive at its inputs can be used.  The device works as follows.  When the power is turned on, all elements of the base unit TV 1 are reset.  The external device (interface equipment) and the control unit 18 exchange information on communication 8 about readiness to receive and receive information.  Data on the tires 25 from the external device is fed to the inputs of the switch 7.  The control unit 18 outputs a counting pulse along circuit 26 to counter 15, a signal along circuit 27 dp passing information through switch 7, along circuit 28 sischap to pass through the switch 19 of the address code from counter 15, type tUM along circuit 30, facing memory block 2 with Record, at the same time, from the output of switch 7 to the input of block 2, information is sent through circuit 31, from switch 19 to.  circuit 32 to block 2 receives the address code of the numeric cell.  In the same way, reception of the following words of information into the buffer zone of memory block 2 is carried out.  After the recording of information into the buffer zone is completed, the ordering and regeneration of information for the indicator is cleared.  The main area of the memory unit 2 is divided into two equal parts, and when information for ordering and regeneration is read from one half-zone, the ordered information is written into the other half-zone.  In the process of work, assignment of half-bursts;) Gots, which is achieved by pre-installing counters 16 and 17 in the corresponding initial states.  Information from the buffer zone is to be rewritten into the main zone with ordering and taking into account the identification.  Counter 16 is used to address the main zone when reading and erasing information, counter 1 only when writing.  Each array of information about the object must include the sequence number of the message entered, the current coordinates and o6bejcTa parameters, for example, height, speed, single number, and so on. P.  After receiving the information from the external source, the control unit 18 through the circuit 33 outputs a signal for resetting the counter 15 and a signal through the circuit 34 to set the counter 16 to its initial state, and the number 16 is entered into the counter 16, one less than the number of the first pike of the main zone, where can stores with information.  Further, from control unit 18 to counter 16, along circuit 35 Bbuiaeiw, there is a counting pulse, and along circuit 36 — a signal l of passage. through the switch 19 of the address via circuit 37 from counter 1b, sipaly through circuit 38 of the call to block 2 with the Read command, one of the group of signals through circuit 39 to enable writing to the corresponding part of the register 4 words of information that appears in the output circuit 20 of memory block 2.  The read operation of memory block 2 is repeated.  The number of repetitions depends on the number of numeric cells that are allocated to store the entire message about a given object.  After the second entry into the register, 4 is complete. & about this object, the control unit 18 extracts the counting pulse along circuit 26 to counter 15, along circuit 28 — signal to pass through switch 19 along circuit 29 of the address from counter 15, along circuit 38 — signals for accessing command memory 2 Reading and one of the group of signals on the 4O circuit for inputting the word of information from the bus 2O in the corresponding.  Value of the register 3.  The read operations of the buffer zone are repeated.  When the last word of this message is entered into register 3, block 18 via circuit 41 outputs a signal to input the result of comparison circuit 42, the code of the sequence (machine) message number from register 4 is sent to one input and the same code from register 3 to the other inputs.  With the equality of the codes at the output of the comparison circuit 42, the corresponding signal appears, which through the circuit 46 through the OR element 68 and through the circuit 69 enters the input of the control unit 18.  This signal stops reading the buffer zone, the signal in circuit 45 resets the contents of register 3, and the signal in circuit 33 clears the counter 15.  The message with the matched machine number must be erased from the main zone, since new information about the same object is stored in the buffer zone.  The signal in the circuit 46 of the control unit 18 generates signals in the circuits 35 and 47, according to which the counter 16 operates in the subtraction mode, t. e.  returns to the code corresponding to the address of the first word of the message to be erased from the main zone.  In the control unit 18, the circuit 36 issues a signal for passing through the address switch 19 via the circuit 37 from the counter 16 and the signals on the circuit 30 to access the block 2 of the memory 510 with the Record command.  The word on the circuit 31 of the inlet of the memory block 2 is not output, therefore in the block 2 O, t is written. e.  erased information.  According to the signals in chains 35, 36 and 30, the words of this message are erased.  When the codes are not equal, the register 3 is reset by the signal of the circuit 45 from the control unit 18, the message about the follower object is written to the register page 3, the results of the comparison circuit 42 are checked.  The process will be repeated until the codes are equal or until the end of the poll / buffer zone. Essentially with the operation of comparing and erasing information, the potential outputs 22 and 4 8 of register 4, connected to the output thickness 24, are used by the indicator to display the information.  From the indicator to block 18.  control of the circuit receives a signal to end the display of information stored in register 4.  If two conditions coincide - the end of erasing the message or the reading of the buffer zone and the end of the display, the signal control block 18 over the circuit 5O resets the register 4.  Further, similarly to the type described, the information on the next object is recorded from the main zone to the register 4, from the buffer zone to the register 3, it is produced.  comparison operations and erase information until counter 16 sets the code corresponding to the address of the last numeric cell where information can be stored.  This code indicates that the information is up-to-date and then proceed directly to the ordering of the information.  The principle of ordering is based on comparing the coordinates of objects taken from the buffer zone and one of the half-blocks of 2 memory.  The ordering of the information begins by setting the counters 16 and 17 to the initial state, depending on which of the half-zones of the main part of the memory unit is stored in the data. Ny moment of information.  Due to the fact that at the beginning of work (the formation will be only in the buffer zone, there is nothing to compare it with.  Therefore, in the order of exclusion, the first, regardless of the coordinates of the object, is rewritten via register 3 to the main zone, and is erased from the buffer zone.  Further ONLY; what is recorded. in the main zone, the message is recorded in register 4 and the next message from the buffer zone is in register 3 and the coordinate comparison operations begin.  8 For this purpose, the unit 18 y: after installing the counters 15-17 into the initial states, the corresponding signals through the circuits m-33, 34 and 51 emit another impulse to the counter 15, the signal for running the control through the address switch 19 via the circuit 29 from the meter, signals via circuit 38 — for accessing memory block 2 with the Read command and the signal from the group of signals over circuit 4O — for recording the information word c. The code of memory block 2 into a certain part of register 3.  The formation of these signals is repeated until it is filled with the full message of register 3.  After that, the control unit 18 generates signals in circuit 52 for polling by switch 7 of register 3, counting pulses along circuit 35 sobbing to counter 16, a signal along circuit 36 for passing the address along circuit 37 from counter 16 through switch 19 and signals along circuit 30 - to access memory block 2 with the Write command.  After the entire message from register 3 is written to the main zln, the control unit 18 returns signals on chains 35 and 47 of counter 16 to the code corresponding to the address of the first numerical cell in which the first word of this message has just been written.  Next, the indicated message is read and written to the register 4. Due to the fact that the first message from the buffer zone is rewritten into the main zone, it must be erased from the buffer zone.  The control unit 18 generates signals in the transmission circuit 26 and 53 to return the meter 15 to the code corresponding to the address of the numeric cell storing the first word of the first message recorded. into the buffer zone.  Next, the first message is erased with signals in chains 26 ,.  29 and 30 transfer.  After erasing, a second message is written from buffer, 1 to register 3.  After the registers 3 and 4 are filled with the insurers, the control unit 18 outputs a signal over the circuit 54 to the coordinate comparison circuit 55 to enter the comparison result.  The code of coordinates along circuit 56 from register 3 is fed to one input of the comparison circuit 55, and the circuit 57 from register 4 to the other inputs.  Depending on the comparison result, the circuit 55 outputs a signal on the circuit 58 to the control unit 18 or on the circuit 59 on the comparison circuit 60.  Object information is not suitable for recording into the main zone under the following conditions: V3 is greater than 4; UZ is equal to Y4 and HZ more than X4; Ultrasound is less than U4 and Ultrasound menus; U5; Ultrasound is equal to y4, HZ mening SW X4 and UZ ultrasound; UZ is less than Y4, UZ is equal to U5 and X3 is less than X5j UZ is equal to U4, X. less than X4 and UZ is equal. Y5, HZ less. X5, Information about the object on the recording of entries into the main zone of the execution of special conditions: UZ is equal to Y4 and X3i: is equal to X4; UZ is less than U4 and UZ is better than U5; UZ is equal to U4, X3 X4 and UZ is greater than U5; UZ less than U4gUZ equal to Y5 and HZ greater than or equal to X5; UZ is equal to Y4 X3 less than X4 and UZ is equal to Y5, HZ is greater or equal to X5.  In accordance with the list of conditions, when ultrasound is greater than Y4, and also when ZS is equal to Y4 greater than X4, comparison circuit 55 sends a message to the IS control unit through circuit 5 that the information about this object does not fit in the recording in the main zone.  When CE is equal to V4 and XZ is equal to X4, the circuit 55 of the comparison across circuit 58 provides the control unit with the signal that the information space on this object is suitable for use.  -. -. -, - With ultrasound equal to Y4 and less than HZ.  X4 or at the VX lower Y4 from the comparison circuit 55, a signal is output along the circuit 59. The comparison circuit 60 is used to enable the output of the comparison result.  At one input of the comparison circuit 60, a code is delivered to the destination along circuit 56 from register 3, to the other inputs — the coordinate code of circuit 2 from register 5, which stores the codes of the last object, information about which is recorded in the main zone from register 4.  In case the ultrasound is less than Y5 or UZ is equal to Y5, and HZ is less than X5, the comparison circuit 6O over communication 61 is applied to the control unit 18. the signal that the information about the object is not suitable: to record at the moment in the main zone IF the same UZ is greater than U5 or UZ is equal to U5, and the HZ is greater than or equal to X5, then the comparison circuit 60 connects the signal 61 to the control unit 18 that information about this object is suitable For recording in the main zone.   a positive comparison result (when the information is suitable for recording) the control unit 18 generates counting pulses along circuit 62 to counter 17, the enable signals along circuit 63 to pass through the switch 19 of the network along circuit 64 from counter 17, and the signal 52 is interrogated by the collector 7 of registry 3, signals on the AOR circuit are processed to memory block 2 with the Record command.  After the end of the census, information from register 3 to the main zone, control unit 18 generates counting pulses along circuit 62 to counter 17, signals on circuits 63 and 65 for polling / register switch 4, signals on access circuit A to block 2 of memory team Record ,.   Simultaneously with recording information from register 4 into the main zone, signal control unit 18 via circuit 12 permits recording of coordinate codes from register 4 to register 5.  Thus, in the register of register 5, the codes of the coordinates of each last object are stored, information about which is written to the main zone during the ordering.  Then, after recording information from registers 3 and 4 into the main zone, the corresponding part of the information is erased from the buffer zone and from the old location of the main zone.  Reading operations of block 2 of memory and comparison of coordinates cease from the signal indicator in the circuit 49 o, the end of the display, after which the signals in chains 45 and 5O registers 3 and 4 are reset, the information from the basic registers is recorded again. and page 4, from buffer to register 3, and coordinates are compared.  If a negative signal of comparison is received via chains 58 or 61 to control unit 18 (information is not suitable for recording), signal control unit 18 to circuit 45 resets register 3i in the same way as above, generates a signal for recording from the buffer zone to information register 3 about the next object and generates a signal over the circuit 45 for (for the derivation of the result of the comparison of coordinates from the circuit 55.  These operations are repeated until the information recorded from the buffer zone to register 3 is suitable for overwriting into the main zone, or until all the numerical cells of the buffer zone have been polled.  In the latter case, when the information recorded in register 3 is unsuitable for recording in the main zone or is missing, information from register 4 is rewritten into the following chiol cells of the main zone 1, and from the old place of the second half of the ocHOBHCrit zone is erased, then upon receipt of a cigar from the indicator on circuit 49, register 4 910 is reset.  Then, all the described operations are repeated on focusing information until the address appears in the counter 16, corresponding to the number of the last numerical cell of that half of the main zone where the information is stored.  As a result of all operations on the ordering of information, the questioned half of the main zone remains free, t. e.  ready to record information in the next cycle.  After the end of the first ordering cycle, part of the buffer zone information rewritten to the main zone during the ordering is erased.  The remaining part of the buffer zone information must be arranged in the following cycles.  Ll of preparation of the next cycle of information management, the block 18 of controlling signals in chains 34 and 51 sets the counters 16 and 17 to their initial states, thereby ensuring the formation of addresses when reading the popup areas where information is stored and recorded when ordered into the free half of the main zone .  After preparing counters 16 and 17, the ordering process is described.  The complete rewriting of information from the buffer zone into the main one with the ordering is done in one or several cycles.  The maximum number of cycles for which all the information in the buffer zone is ordered depends on the ratio of the coordinates of objects that are received into the buffer zone and may be equal to their number, due to the fact that the frame period of most indicators is 4 -20 m maximum delay in displaying information on the display will be a fraction of a second, which is adequate for most cases.   When reading the buffer zone and writing information to the register 3, the block 12 control-: le11Y along the circuit 66 is signaled that the register is occupied with information.  If, while reading the entire buffer zone, the control unit 18 does not receive any signs of busyness along circuit 66, this means that all the information from the buffer zone is copied to the main zone, and the buffer zone is free.  After that, the control unit generates all the necessary signals to read the main zone and write to register 4 to be displayed on.  comparison operation indicator is prohibited.  The information in the short-circuit register 4 is rewritten to the new places of the main zone, while the signal in the circuit 49 causes the register 4 to be reset.  This happens until the end of the cycle (indicator frame).  After that, counters 16 and 17 are prepared for operation in the next cycle, and a signal is sent to an external source that it is ready to receive a new piece of information in the buffer zone.  When the source is ready to transmit information, it is received: into the buffer zone, then the information is output to the indicator with simultaneous ordering.  Simultaneously with the ordering of information, the device produces its identification.  When comparing the coordinate codes recorded in registers 3 and 4, the additional output 72 of the comparator 6 may show the equality signal of the old bits of the coordinate codes X and Y.  The number of compared high-order bits is determined by the magnitude of possible errors in the formation of the coordinates of one and the same object from different radar sources, the possible speed of movement of the object and the price of the least significant bit.  For example, each of the, coordinates X and Y is given in ten bits.  The price of the younger category is 200 m, respectively, the price of the AES of that category is 4OO m and so on. d.  With a possible (predetermined) aforementioned error of 5–10 km, comparison can be made for 4–6 older ones, per diem.  The comparison is carried out separately by the coordinates X3, X4 and UZ, Y4.  Upon the occurrence of signals Equal to the outputs of both high-order comparison circuits, an additional coincidence element is triggered, which is part of the comparison circuit 55, (not shown) and a signal appears on the bus 72 that allows the output of the comparison result from the additional block 67.  Codes of parameters of objects are supplied to the inputs of the comparison block 67.  In addition to the coordinates, the air object is characterized by the sign of belonging (own or alien), height, speed, and so on.  Identification of information is carried out by comparing the main parameters. For example, identification can be made except coordinates on the basis of belonging to a height. With the same compared parameters on the output bus 70 of the block 67 of the comparison, an Equal Signal passes through the element OR 68 and the bus 69 goes at block 18

management On this signal, the message recorded in register 4 must be erased from the main eaaa, since in the buffer zone Kpaitjnca there is more new information about the same object. On a signal in circuit 69, the control unit 18 generates counting signals in chains 35 and 47, according to which counter 16 is operated for subtraction, i.e. The return code is a code corresponding to CH) to the first word of the co & t value, which must be erased from the main page. Next, the control unit 13 outputs a signal through circuit 36 of the cc link through the aores switch 19 across the circuit 37 from the counter 16 and the signals through the aura circuit to access the memory block 2

with the Record command. The word on the circuit 31 to the inputs of the memory block from the switch 7 is not output, therefore, in block 2, an O. (erasure of the information) is recorded. Subsequent words of this message are erased by signals from circuits 35, 36 and 30 of control unit 18.

The proposed device provides an extension of the functionality, since in addition to solving the main tasks of ordering and regenerating information for the indicator, it allows identification. Blur the information, and no additional time is spent on this operation (the display time of the information on the indicator is used).
