However, this device does not allow the operator to record the moment of the occurrence of any of all sequentially generated sync pulses, which, for example, transfer information bytes. The absence of such a function does not allow for the prompt monitoring of, for example, the state of the electrical patterns of a paired device operating under the influence of clock pulses, which reduces the speed of the device.

The aim of the invention is to improve the speed of the device. This goal is achieved by the fact that, in a device for recording information in a random-access memory, a pulse distributor, connected to a local control unit, a synchronization unit, a code sensor, the output of which is connected to the information input of the code converter, an information input unit, the outputs of which connected to the information inputs of a single pulse generator, one of the control inputs of which is connected to the control converter of the code converter, the information output of the code converter being connected one of the control inputs of the pulse distributor and are the formation outputs of the device, one of the outputs of the synchronization unit is connected to the other control inputs of the pulse distributor and the single pulse generator and the control inputs of the code converter and are together with the output of the single pulse generator. from the control outputs of the device, a comparison circuit, a counter, a decoder, AND and OR elements and a trigger are introduced, with the information outputs of the code converter connected to one of the inputs of the comparison circuit and the inputs of the first element I, the output of which is connected to the first input of the counter, the second output of which is connected to the output of the generator of single pulses, and the outputs are connected to the first inputs of the second and third elements And, the outputs of which are connected to the inputs of the element And the output of connected to a single trigger input, the zero input of which is connected to the output of the comparison circuit, and the output is another control output of the device, the other inputs of the comparison circuit and the second input of the second and third elements are AND other outputs sync block., In FIG. 1 shows a structural diagram of the proposed device in FIG. 2-4 block diagrams of a synchronization unit, a pulse distributor, and a code converter, respectively; in fig. 5 is a diagram of the arrangement of the windings in the local control unit; FIGS. 6-8 are timing diagrams explaining the operation of the device. The device for recording information into the operational memory (Fig. 1) contains a synchronization unit 1, a pulse distributor 2, a 3-month control unit made in the form of a tablet, a 4 code sensor, a 5 code converter, an information input block b, a single pulse generator 7 , comparison circuit 8, counter 9, decoder 10, first 11, second 12, third 13 AND elements, OR element 14, trigger 15, display elements 16-18. Positions 19 to 99 denote the connections between the outputs and the inputs of the device units (including the positions, 53-70, the windings of unit 3). The synchronization unit 1 (Fig. 27 contains a pulse generator 100, a counter 101, a decoder 102-105, And 106 elements - 110. A pulse distributor 2 (Fig. 3 contains And 111-134 elements. The converter 5 of codes contains (Fig. 4) a trigger 135, elements AND 136 - 137, element OR 138 ,. triggers 139, 140, element AND 141, counter 142, elements AND 143-147, element OR 148, element AND 149, elements OR 150, 151, triggers 152, 153, counters 154, 155, triggers 156-158. Block 3 contains (Fig. 5 in the X coordinate a group of loop-like windings 53-56 and two groups of single-loop windings 61-63 and 64-66, and in the Y coordinate - a loop-like windings 57-60 and two groups of single-circuit windings 67, 68 and 69, 70. Coordinate grid of block 3 has 16 rows and 24 columns. Rows correspond to bits Y1, Y2, UZ, Y4 of binary code. Columns of the coordinate field of block 3 correspond to bits XI, X2, X3 X4 binary code. The left coordinate field, formed by 16 columns, is intended for reading the byte code, the right field is intended for setting the operation modes. The device works as follows. Unit 1 continuously produces pulses at the outputs 19-52 (Fig.6-8). The continuous cyclic operation of block 1 is ensured by a counter 101 operating under the influence of pulses at the output 19 of the generator 100. The duration of the pulses at the output 19 is approximately 1 μs. The pulses at the outputs 32-35 of the decoder 102 and the outputs 36-39 of the decoder 103 are produced during the entire cycle of operation of block 1. The decoder 104 operates only at the moment of the pulse at the output 46 of the decoder 105. The decoder 102 105 ensures the sequence of operation of all the blocks of the device. Each cycle of operation of block 1 is divided into main clock cycles, determined by the presence of signals at outputs 46-48 of decoder 105. In the first main cycle, a coordinate code is generated at the output of converter 5 and generator 7 is operated when the button of block 6 is pressed (Fig. 1) not shown)

At the beginning of each cycle of operation of block 1, the counter 101 is in the state O, and at this time the signals at the outputs 32, 36, 40, 46 are generated, affecting the AND107 element. The signal at the output 50 of this element is used for setting :: setting in O converter 5. This signal is fed to the inputs of counters 142, 154, 155, flip-flops 152, 153, 156-158.

During the operation: pulse Hai, output 40 of block 1 sequentially produces four pulses at the outputs of distributor 2, which enter the windings 53-56 of block 3. As a result of polling these windings, a four-digit code appears at the output of sensor 4. The code combinations of this code are 1000, 1100, 1110, 1111, 0111, UN, 0001, 0000, the other combinations are not used. Trigger 139, AND elements 136, 137, 144, 145, OR elements 150 trigger 152, counter 154 take part in the conversion of this code into a three-bit binary code, and at outputs 71, 72 of counter 154 a code K1, X2 is formed, and output 7 trigger 152 - code HZ.

During a pulse at output 41 of block 1, current pulses from the outputs of distributor 2 enter windings 57-60 of block 3. As a result of polling these windings, a four-digit code also appears at the output of sensor 4, which is converted to a three-digit binary code Y1, Y2, Y3 at the exits 76-78. The trigger 135, the elements AND 136, 137, 146, 147, the element OR, 151, the trigger 153, the counter 155 participate in the conversion of the code.

During the action of the pulse at the output 42 of the unit 1, the windings 61-63 or 64-66 are polled. The winding 61-63 is polled with elements and 119, 129, 130, 131, and the winding 64-66 is polled with elements And 120, 132-134. The logical interrogation is controlled by the signals at the output of the trigger 152. As a result, the interrogation of the windings 61-63 or 64-66 at the output of the sensor 4 appears a three-digit code, represented by a unit in only one of the bits. Possible combinations of this code are 100, 010, 001. Trigger 135, element 136, triggers 156, 157 are involved in converting this code into a two-digit binary code. The X4, X5 codes are set at outputs 74, 75 of the triggers 156, 157.

During the action of the pulse at the output 43 of the unit 1, the windings 67, 68 or 69, 70 are interrogated using the elements I 111, 113, 114 or the elements I112, 115, 116.

Poll windings 67, 68 or 69, 70 at the output of sensor 4 appears two-digit code, represented by a unit in only one bit. A trigger 135, element I 136, trigger 158 take part in the conversion of this code, at outputs 79, 88 of which the code Y4, Y4 is formed.

During the action of the pulses at the outputs 42, 43 the code from the sensor 4 through the trigger 135, the elements 136, 141 goes to the counter 142. When working properly on the control output 89 of the element 149, the signal arrives at the display element 16 and into the generator 7. The code at the outputs of converter 5 is saved until the end of the operation cycle of block 1.

The generator 7 only works when the button of the block 6 is pressed. Two additional modes of operation are achieved using counter 9. The code state of counter 9 changes when reading the code of the coordinates of that square in the control field of block 3, the code of which can pass through the I 11 element. the first additional mode should burn the element

18indications When the first mode is set, the signal from output 51 of the unit 1 h. Cut element AND 12 and element OR 14

sets the trigger 15 to position 1. The trigger 15 is set to O by the signal from the output of the comparison circuit 8.

When installing the second mode, the trigger 15 is set to 1 by the signal from the output 52 of block 1.

At the time of installation of the trigger 15 in position 1 on all outputs 23 29 of the counter 101 is set to zero signals.

The comparison circuit 8 produces a pulse only when the code at the outputs 23-29 is compared with the coordinate code of the square above which the sensor 4 is located. During the trigger time 15, a certain number of pulses are generated at the outputs 32-34. For example, the coordinates of the first square in the byte field, ea, the response time of the trigger 15 produces only one pulse or output 32, and when reading the coordinates of the sixteenth square, 16 pulses. The number of pulses at output 32 during the response time of trigger 15 depends on the position of sensor 4 on the floor, bytes of block 3.

This dependence is used to control the transfer of bytes, which occurs under the influence of pulses at the output 32 of block 1. In this case, it is convenient to use a simple correspondence between the numbers of squares of the byte zone of the coordinate field of the block and 3 to the numbers of successively transmitted bytes. The device allows the operator to view the situation that occurs at the time of the transfer of a byte. To do this, the operator must combine sensor 4 with the square corresponding to the transmitted byte number. The control signal for the conjugate device is generated by the trigger 15 under the influence of the pulse of the comparison circuit 8 in each cycle of operation of the block 1. Introduction to the known device of new nodes, in particular the comparison circuit, the counter, the decoder, the trigger, the three AND elements, and the corresponding communication enhances its functional capabilities and improves speed. The proposed device allows the operator to record the moment of the occurrence of any of all sequentially generated sync pulses, under the influence of which, for example, the transfer of information bytes. In the described device there are two additional modes of operation. differing in the intersection of sync pulses only. In both modes of operation, the correspondence of the serial numbers of the sync pulses to the serial numbers of the squares of the grid is used. To fix the moment of occurrence of any sync pulse, the operator simply needs to combine the code sensor with the corresponding square of the tablet grid. The signal produced by fixing the moment of the occurrence of a sync pulse is used, for example, to conduct a visual check of the state of the electrical circuits of both the proposed and the conjugate device.
