A two-channel programmable pulse generator operates as follows ..

Timing diagrams of the operation of the generator are presented in Fig.Z.

The information inputs of the generator are the information inputs of the sensors 22-31. Before starting work on the information inputs of the sensors, the appropriate codes must be set programmatically, the Generator can operate in six modes in accordance with the time diagrams presented in Fig.Z. where UV1 is the output of the first channel of the generator, Vebix2 is the output of the second channel of the generator, T1 is the duration of the first pulse, T2 is the duration of the first pause, TK is the duration of the second pulse, T4 is the duration of the second pause. Moreover, the period of the generated sequence for both channels in the general case (Fig. 3a) is determined as follows:

Channel I T1 + T2 + TK + T4, channel II

in all other cases, some summands are equal to zeros) (Fig. 3b-e). Therefore, before starting work on the information inputs of the sensor 31 of the primary conditions, a code must be set corresponding to the selected operating mode in accordance with Fig. Za-e, while the logical level 1 at the outputs of the sensor 31 indicates that this parameter is set, and the logical level A indicates that the parameter is not set. The correspondence of the outputs of the sensor 31 is determined as follows: the first output corresponds to the first pulse), the second output to the first pause (T2), the third

the output is to the second pulse (TK), the fourth output is to the second pause (T4).

The generator always starts work only with a pulse, and if T1 10, then T2 0; if, then.

The duration of any pulse or pause is determined as follows:

tKi K2

Tl, 2.3.4, TO

0 where f0 is the frequency of the master oscillator;

Ki is the division coefficient set in the timing sensors 22-25;

Ka is the division coefficient set in the duration sensors 26-29.

5 The control inputs of the generator are the inputs: mode selection (second input of the GI 2 element), installation input (third input of the GI 2 element), triggering the input (first input of the first trigger 4, second

0 input of the second element 2 AND 14, first input of the third element 2 AND 15, second input of the fourth 16 and fifth of the 17 elements 2 AND and the seventh input of the control unit 18). Before starting work, all control inputs must have a single level - from the buttons or programmatically.

At the installation input of the generator a low-level pulse is supplied, which with-

0 stroke element ZI 2 goes to the second input of the first trigger 4 and sets its direct output low level, prohibiting the passage of the clock frequency from the master oscillator 1 through the first 5 input of the first element 2I 3. At the same time, a low level signal from the output of the element ZI 2 is received to the installation input of the subtracting counter 19, entering into it the code of the number of pulses in

0 sequences from the output of the sensor 30. At the same time, the low-level signal from the installation input of the generator goes to the eighth input of the control unit 18, where through the second input of the seventh element 2I 38,

5, the first input of the sixth element 2I 36 installs low-level signals at the direct outputs of flip-flops 37 and 39, which, through the first inputs of the second element 2I-NOT 33 and the fourth element 2I-NOT 35, set unit levels at the second and fourth inputs of the control unit 18 prohibiting the operation of multiplexers 7 and 9, respectively, as well as through the second input of the ninth element 2I 52 and the first input of the twelfth

5 elements 55 create at the eighth and eleventh outputs of the control unit 18 low-level signals that, through the fourth inputs of the second 20 and third 21 triggers, set their direct outputs

to the zero state (outputs of both channels) and at the first and sixth inputs of the control unit 18, low-level signals are established, which are installed on the first input of the 2I-NOT 32 element and through the second input of the third-5th of its 2I-NOT 34 element and the third outputs of control unit 18 are unit levels prohibiting the operation of multiplexers b and 8, respectively.

In the general case, when all the parameters are set - 10 meters (T1.T2, TZ.T4, i.e., at the outputs of the sensor 31, the logic level 1 is set to logic 1 from the first to the fourth), when the low-level signal is received at the start-up input of the generator the inputs of the first 15 10, second 11, third 12, fourth 13 DPKD through the second input of the second element 2I 14, the first input of the third element 2I 15, the second input of the fourth element 2I 16, the second input of the fifth element 2I 17, respectively, receives a low signal level for

the nose in the DPKD 10-13, respectively, the information from the outputs of the sensors 22-25, The same trigger signal through the first input of the first trigger 4 generates a high level signal at its 25th direct output: received at the second input of the first element 2I 3 and allowing the clock frequency to pass through the first input of the first element 2 AND 3 to the counting input of a decadal frequency divider 5, at the output of which n frequencies are formed that are multiples of ten (n is the number of decades of a decadal frequency divider 5), which are fed to the information inputs of b, 7, 8, 9, n 35 steering inputs which set the frequency codes of timing pulses and pauses in the sequences. The same trigger signal is fed to the seventh input of the block. ka 18 control and through the first input 40 of the eighth element 2I 51 is supplied to the seventh output of the control unit 18. Since the first output of the sensor 31 of the primary conditions has a single level, the sixth output of the control unit 18 and, accordingly, the second input of the second trigger 20 will also have a single level, and the tenth output of the control unit 18 and co. Responsibly, at the second input of the third trigger 21 through the inverter 50, the logic O level is set to 50. Thus, after the start pulse from the seventh output of the control unit 18 arrives at the third inputs of the second 20 and third 21 triggers at the direct output of the third 55 trigger 21 the level of logical O is confirmed, and at the direct output of the second trigger 20, a single level is established - the formation of the first sequence begins, which arrives at the first input of the control unit 18 and through the first input of the first element and 211-methane. 32 generates a low level signal at the first output of the control unit 18 enabling operation of the first multiplexer b. at the control inputs of which the clock frequency codes of the first pulse are set. The corresponding frequency selected by the multiplexer comes from its output to the counting input of the first DPKD 10, at the information inputs of which the code for the duration of the first pulse is set, i.e. code defining a holding time at the output of the second unit level trigger 20. At the end of the counting, the output of the first DPKD 10 forms a low-level signal, which passes through the first input of the second element 2I 14 to the installation input of the first DPKD 10. prepare it for further work, as well as the signal from the output of the first DPKD 10 goes to the second input of the control unit 18. where through the first input of the ninth element 2I 52 (at the second input of the ninth element 2I 52, at the end of the installation signal, the logic level 1 is present), it goes to the eighth output of the control unit 18 and is installed through the fourth input of the second trigger 20 low level at the output of the first channel of the generator, and also through the first input of the control unit 18 and its first output prohibits the operation of the first multiplexer 6. At the same time, the signal received at the second input of the control unit 1 through the inverter 40 is fed to the first input of the fifth element 2I-NOT 46. where it is blocked by a low level from the output of the second inverter 41, at the input of which there is a single level from the second output of the sensor 31. At the same time, the signal received at the second input of the control unit 18 through the first input of the fourth trigger 39, and then through the first input of the second element 2I-NOT 33 (at the second input of which there is a unit level from the second output of the sensor 31), forms a low level on the second output of the control unit 18, allowing the operation of the second multiplexer 7, at the control inputs of which code for the clock frequency of the first pause. The corresponding frequency selected by the multiplexer 7 comes from its output to the counting input of the second DPKD 11, at the information inputs of which the code for the duration of the first pause is set. At the end of the count, a signal is generated at the output of the second DP KD 11; low level, which through the second input of the third element 2I 15 enters the installation input of the second DPKD 11, preparing it for further work. The low-level signal from the output of the second DPKD 11 also goes to the third input of the control unit 18, where through the first input of the seventh element 2I 38 it enters the second input of the fourth trigger 39, forming a low level at its output, and through the first input of the second element 2I-NOT 33 generates a signal that prohibits the operation of the second multiplexer 7. The low-level signal received at the third input of the control unit 18 simultaneously passes through the third inverter 42 to the first input of the sixth element 2I-NOT 47 (at the second input of which there is a single a ram from the third output of the sensor 31) and generates a low level signal at its output, which through the second input of the tenth element 2I 53 (at its first input, the unit level from the output of the fifth element 2I-NOT 46 is confirmed by the unit level from the second output of the sensor 31 through the inverter 41 and the second input of the fifth element 2I-NOT 46) is supplied to the ninth output of the control unit 1b, and accordingly, the first input of the third trigger 21 is not set to its single state, thus starting to form a second pulse, which is weekend to them pulse of the second channel of the generator. At the same time, this unit level is fed to the sixth input of the control unit 18, where, through the second input of the third element 2I-NOT 34, it generates a signal on the third output of the control unit 18 that allows the third multiplexer 8 to operate, on the control inputs of which the clock frequency code of the second pulse is set. The corresponding frequency selected by multiplexer 8 is fed to the counting input of the third DPKD 12, at the information inputs of which a code for the duration of the second pulse is set, i.e. a code defining a holding time at the output of the third unit level trigger 21. At the end of the counting, the output of the third DPKD 12 generates a low-level signal, which through the first input of the fourth element 2I 16 is fed to the installation input of the third DPKD 12, preparing it for further work, and the signal directly from the output of the third DPKD 12 is sent to the fourth input of block 18 control, where through the second input of the twelfth element 2I 55 goes to the eleventh output of the control unit 18 and, accordingly, to the fourth input of the third trigger 21, setting its output low - at the output of the second anal generator - and inhibit the sixth block input through the control 18, and then through the second

the input of the third element 2I-NOT 34 and the third output of the control unit 18 the operation of the third multiplexer 8. The signal received at the fourth input of the control unit 18, through

the sixth inverter 45 is fed to the second input of the eighth element 2I-NOT 49, where it is blocked by the signal from the fourth output of the sensor 31 through the fifth inverter 44. At the same time, the signal from the fourth input

0 of the control unit 18 through the first input of the fifth trigger 37 and the first input of the fourth element 2I-NOT 35 generates at the fourth output of the control unit 18 a signal enabling the fourth multiplexer

5 to 9, at the control inputs of which a second pause clock code is set. The corresponding frequency selected by the multiplexer 9 is fed to the counting input of the fourth DPKD 13. at the information inputs of which a code for the duration of the second pause is set. At the end of the counting, the output of the fourth DPKD 13 produces a low-level signal, which through the first input of the fifth element 2I 17

5 goes to the installation input of the fourth DPKD 13, preparing it for further work, and the signal directly from the output of the fourth DPKD 13 goes to the fifth input of the control unit 18, where through the second input of the sixth element 2I 36 it goes to the second input of the fifth trigger 37 and sets at the fourth output of the control unit 18 through the output of the fifth trigger 37 and the first input of the fourth element 2I5 NOT 35 a signal prohibiting the operation of the multiplexer 9. At the same time, the signal received at the fifth input of the control unit 18 through the second input of eight My item

2and 51 goes to the seventh output of block 18

0 control, from this moment the operation of the generator is repeated.

The operation of the generator in continuous mode is described above, when a low-level signal is applied to the control input of the generator Selecting the end mode of the setup signal, which blocks the possibility of switching the first trigger 4 to the second input. If a mode with a limited number of pulses is selected in

0 sequences, then a single level must be present at the control input of the generator. Then, upon entering the subtractive input of the counter 19 from the twelfth output of the pulse number control unit 18 equal to the set number of pulses at the information inputs of the counter 30c of the output of the sensor 30, the internal bits of the counter 19 are zeroed and a low-level pulse is generated at its output, which the first input of the ZI 2 element arrives as the installation input of the subtracting counter 19, introduces a new value of the number of pulses into it and into the second input of the first trigger 4, where t at its direct output is a low level that prohibits the passage of the clock frequency from the output of the master oscillator 1 to the counting input of the decade frequency divider 5, thus completing the formation of sequences with a given number of pulses at both outputs of the generator. The signals at the twelfth output of the control unit 18 are generated using the 2I-2OR-NOT 56 element, the first input of which through the fourth input of the control unit receives a signal from the output of the third DPKD 12, and to the third input of the 2I-2OR-NOT 56 element a signal is received through the second input of the control unit 18 from the output of the first DPCD 10. Thus, a signal is generated at the output of the 2I-2OR-NOT 56 element either from the output of the third DPCD 12 or from the output of the first DPCD 10 depending on the signal at the third output of the sensor 31 primary conditions that is connected directly to the second input of the element 2I-2 OR NOT 56, and to the fourth input of this element through the fourth inverter 43. Thus, for the sequences depicted in Figs. C-c, e, e, pulses at the twelfth output of the control unit 18 are generated by the output signal the third DPKD 12, and for the sequence shown in Fig. 3g, pulses at the twelfth output of the control unit 18 are generated by the signal from the output of the first DPKD 10.

The operation of the generator in the mode indicated in Fig. 36. The generator generates the first sequence, as in the case shown in Fig. 3a, as well as the pulse in the second sequence, but due to the fact that here the duration of the second pause is zero, a low level is set at the fourth output of the sensor 31 of the primary conditions. which through the second input of the fourth element 2I-NOT 35 blocks the setting of the resolution signal for the fourth multiplexer 9 on the fourth output of the control unit 18, but at the same time through the fifth inverter 44 it enters the first input of the eighth element 2I-NOT 49, by themselves m allows at its output the formation of a low-level signal when it arrives at the fourth input of the control unit 18 of such a signal from the output of the third DPKD 12, which through the second input

of the eleventh element 2I-NOT 54 and the fifth output of the control unit 18 is supplied to the first input of the second trigger 20, and the operation of the generator is repeated. The establishment of the output of the third trigger 21 of the low level occurs as described above (as in the case indicated in FIG. 3a).

The operation of the generator in the mode indicated in FIG. The generator begins to form the first sequence, as in the case indicated in Fig. 3a, but since the sensor 31 of the initial conditions have low levels at the second and fourth outputs, then the second and second elements 32I-NOT are blocked through the second inputs of the second 32 and fourth 35 the fourth outputs of the control unit 18, and through the second 41 and fifth 44 inverters, the operation of the fifth 46 and eighth 49 elements 2I-NOT is allowed. Thus, when a low-level signal is received at the second input of the control unit 18 from the output of the first DPCD 10 through the first input of the ninth element 2I 52, the eighth output of the control unit 18, as well as the fourth input of the second trigger 20, a low level is formed at the first output of the generator, which through the first input of the control unit 18, the first input of the fifth element 2I-NOT 32 and the first output of the control unit 18 prohibits the operation of the first multiplexer 6. At the same time, the low-level signal from the output of the first DPCD 10 received at the second input of the control unit 18 through the first inverter 40 and the first input of the fifth element 2I-NOT 46, as well as through the first input of the tenth element 2I 53, it enters the ninth output of the control unit 18, where through the first input of the third trigger 21 it forms at its direct output ( the output of the second channel of the generator) is a single level and through the sixth input of the control unit 18 and the second input of the third element 2I-NOT 34 forms at the third output of the control unit 18; a signal allowing the operation of the third multiplexer 8 and the third DPKD 12, which at the end of the count generates a low level signal at the fourth input of the control unit 18, which, as described in the case shown in Fig. 36, generates a low level at the output of the second sequence, and my output of the second flip-flop 20 is again set to a single level and the operation of the generator is repeated.

The operation of the generator in the mode indicated in FIG. The generator generates the first sequence, as described above, indicated in Fig. 3a, but due to the fact that the third and fourth outputs of the sensor 31 are set to low levels and through the first input of the third element 2I-NOT 34 and the second

the input of the fourth element 2I-NOT 35 the third and fourth outputs of the control unit 18 are blocked, its low level is blocked at the third output of the sensor 31 through the second input of the sixth element 2I-NOT 47, but through the fourth inverter 43 and the second input of the seventh element 2I-NOT 48 the latter is allowed to work, then when a low-level signal is received from the output of the second DPKD 11 to the third input of the control unit 18 and through the third inverter 42 and the first input of the seventh element 2I-NOT 48, as well as the first input of the eleventh element 2I 54, the fifth output of block 18 management neither the first input of the second flip-flop 20 at its output again forms a unit level and the operation of the generator is repeated; at the same time, the output of the second channel remains low all this time.

The operation of the generator in the mode indicated in Fig.Z. The generator begins to form the first sequence, as in the case indicated in FIG. 3a, but due to the fact that the second output of the primary condition sensor 31 has a low level that blocks the second output of the block through the second input of the second element 2Y-NOT 33 18 of the control and through the second inverter 41 and three times the input of the fifth element 2I-NOT 46 allows the latter to work on the first input, thus, when the second input of the control unit 18 receives a low level signal from the output of the first DPKD 10 at the eighth output of the control unit 18 the first input of the ninth element 2I 52 also generates a low level signal, which through the fourth input of the second trigger 20 sets the output of the first channel of the generator to a low level, which also prohibits through the first input of the control unit 18, the first input of the first element 2I-NOT 32 and the first output of the block 18 controls the operation of the first multiplexer 6. At the same time, the signal from the output of the first DPKD 10 through the first inverter 40, the first input of the fifth element 2I-NOT 46, the first input of the tenth element 2I 53, the ninth output of the control unit 18 and the first input third its trigger 21 forms a single level at its output (at the output of the second channel of the generator), and then the operation of the generator continues, as described above, when operating in the mode indicated in FIG.

The operation of the generator in the mode indicated in FIG. Due to the fact that the first and second outputs of the primary condition sensor 31 are set to low, the first and second outputs of the control unit 18 are blocked through the second inputs of the first 32 and second 33 elements 2I-NOT. So

images, at the output of the first channel of the generator no changes occur and the low level set at the beginning of operation after the low level signal is received at the installation-input of the generator is maintained. Due to the fact that the low level c of the first output of the sensor 31, received at the sixth output of the control unit 18, and, accordingly, at the second input of the second trigger 20, does not allow this, the trigger switches when it arrives at the seventh output of the control unit 18 through the first input of the eighth element 2 AND 51 and the seventh input of the control unit 18 of the generator pulse starting 5, with the same pulse received at the third input of the third trigger 21, the last is set to a single level, since the seventh inverter 50 is created at its second input

0 unit level from the first output of the sensor 31. Thus, at the output of the second channel of the generator upon receipt of a triggering pulse, the formation of a unit level begins, further

5, the formation of a pulse at the second output of the generator, as well as the formation of a pause at the second output of the generator, occurs, as in the case indicated in FIG. 3A and described above. At the end of the account, the fourth DPKD

0 13 a low-level signal from its output through the fifth input of the control unit 18 and the second input of the eighth element 2I 51 goes to the third inputs of the second 20 and third 21 triggers, but since switching the second

5 of the trigger 20 is prohibited by a low level at its second input (from the first output of the sensor 31), and the switching of the third trigger 21 is allowed by a single level at its second input, then switching occurs

0 of the third trigger 21, and then the operation of the generator is repeated.

Changing the parameters and types of generated sequences is done by setting the appropriate codes in sensors 22-31

Compared with the known technical solutions, the proposed pulse generator allows you to expand the functionality of the device: the ability to create two sequences, the ability to independently change any of the parameters in any sequence, the ability to obtain sequences where pulses are never 5, do not follow at the same time, this property can be used in various control devices: the ability to generate pulses both in continuous mode and in a mode with a given quantity pulses in the sequences

the possibility of the generator in six of these modes.
