The appearance of the clock indicator (Fig. 3a) is presented in the form of minutes, hours and the seconds indicator, and the arrow itself (Fig. 36) is divided into eight sectors, each of which is an indicator LED.

Electronic clock with pseudo-switch indication works as follows.

At the initial point in time, a supply voltage is applied to the power bus 8. At the first output 43 of the generator 1, pulses appear with a period of 1 s, arriving at the counting input 42 of the first counting trigger 9 and at the third input 65 of the register 18,

To set the clock to the initial state, briefly the initial setting button 34 is closed. From the power supply spikes, a current flows through the resistor 16 and the start-up LEDs 28 to 30. Triggers 9-11 are set to one state, since their installation inputs 56 have 1, coming from the output of the second opto-electronic converter 27, on the optical input of which the signal from the first triggering LED 28 is received.

In addition, from the triggering LEDs 28-30, additional photo thyristors 44, 50, 55 are supplied to all the counters 2, 3, 4 and put them into the conducting state. Since the flip-flops 9-11 are in state 1, a zero potential appears at the outputs of the first, third, and fifth keys 19, 21, 23, and therefore current flows through additional photo thyristors 44, 50, 55. The first bits 38.1, 48.1, 53.1 of all the counters 2, 3, 4 go into the excited state. These bits of the game are BEGINNING initial, i.e. the second mark (fng.Z), the goshutna and the hour hand are opposite the division corresponding to the twelve o'clock

The clock can operate in two modes: the marker marker display mode and the arrow display mode.

In the first mode, the switch 37 is open. The potential of the logical unit is fed to the first input of 63 register 18. From the third output 66

The controller I to the second input 64 of the register 18 receives pulses with a frequency of above 50 Hz. The register 18 in this mode operates in a single position code, t, eo there occurs a sequential shift of the logical unit towards the higher bits 85 (FIG. 2) „

At the initial moment on the first output 61 about 1 of the register 18 there is a single potential. The current will flow from the first output 61.1 through the first indication LED 59 of the first row of the matrix for 6 hours, the second isolating diode 60, the photo thyristor 55 or 52 of the first discharge I 53 about 1 counter 4 hours to the output of the fifth key 23 o

With the arrival of the first pulse to the second input 64 of the register 18, the unit potential switches to the second output 61.2. The first indicator LED 59 of the second row of the matrix 6 of the clock indicators (the second sector from the bottom (Fig. 36)) is illuminated, and the first row is the damper, etc.

With the arrival of the fifth pulse, the unit potential moves to the sixth output 61.6 of register 18, the current from which will flow through the resistor 31. The first indicator LED 62 of the first row of the matrix 5 minutes indicators, the photo thyristor 50 or 47 to the output of the third key 21. Accordingly, this indicator LED 62 lights up (third sector from the top (FIG. 3b)), etc.

At the moment the first pulse arrives at the counting input 42 of the first flip-flop 9, the flip-flop 9 switches to the opposite state. At the output of the second key 20, a potential of zero appears. The second discharge phototiristor 38.2 of the counter is 2 seconds, due to the presence of an optical signal from the first discharge 38.1 LED 40, it goes into a conducting state, i.e., the corresponding indicator LED 41 transmits the current through it. On the indicator (Fig. 3a), this will correspond to the movement of the light mark, around the perimeter of the indicator one small division in a clockwise direction. With the arrival of the second pulse, the trigger 9 switches to the opposite state. A third bit of 38.3 counter is excited for 2 seconds,. light schA with a second

the label will move to the second small division of the indicator (FIG. 3), etc. With the arrival of the sixty pulse, the output of the first optoelectronic converter 17 is a pulse arriving at the first input of the first element OR 25, from the output of which it goes to the counting input 46 of the second flip-flop 10, which switches to the opposite state. The second bit of the 48.2 counter of 3 minutes is energized, i.e. the minute hand (fig. 3) is moved one division clockwise, and the clock remains in place. The processes occurring in the second columns of both matrices 5 and 6 are similar to the processes in the first column in the initial state. With the arrival of the eleventh pulse on the counting

the input 46 of the second trigger 10 excites the twelfth bit 48.12,

the optical signal from the LED 49 of which is fed to the first optical input of the optoelectronic circuit OR 7, from the output of which an electrically pulse through the second element OR 26 is fed to the counting input 51 of the third trigger 11, which switches, and therefore, the second bit 53.2 of the counter 4 hours, those. the hour hand (fig. 3) will move one small division of the dial (1/5 h).

Further processes will be carried out in a similar manner. Since the pulse frequency at the third output 66 of the generator 1 is high, the blinks on the indicator LEDs 59 and 62 will not be visible. Light solid arrows will be observed.

In the second mode, the switch 37 is closed. The second input 64 of the register 18 is turned off, and the third input 65 from the first output 43 of the generator 1 receives pulses with a period of 1 s. With the arrival of the next pulse to the third input 65 of the register 18, there is an increase (saturation) of the single potentials at the outputs 61 towards the higher ones. The indicator LEDs 59 and 62 in the respective columns of the matrix 5 and 6 are sequentially illuminated. On the indicator (Fig. 36), this is represented by the successive excitation of the LED from the beginning of the arrow. With coming

In the fifteenth pulse, register 18 is zeroed out and the building process begins anew.

For the initial setting of the hour hand, the button 36 closes. The pulses of the second output 45 of the generator 1, the follow-up period of 0.5 s, arrive at the first input of the second element OR 26, from the output of which to the counting input 51 of the third trigger 11 "The corresponding excited bit is set d 53 counters 4 hours, i.e. the clock is set to the required position on the indicator. After that, the button 36 is opened.

A minute hand is set in the same way, only by pressing button 35.

The keys 19-24 are implemented on the basis of n-p-n type transistors, the collectors of which are the outputs of the keys. The resistors in the circuit are needed to set the operating currents in the corresponding circuits. Generator 1 is implemented with frequency dividers, the outputs of which are the outputs of oscillator.

Register 18 operates as follows

In the first mode, at the first input 63 of the register 18 is present 1. Accordingly, at the output of the element And 75 with an inverse input is present O. The initial setting of the register 18 is carried out similarly to that considered. 70, from the output of which, through the OR element 84, they arrive at the counting input 90 of the flip-flop 69, which begins to switch,

With the arrival of the first pulse, the trigger 69 goes into a single state. At the output of the second element, AND-NE 79, 1 appears, coming through the third element 72 and 72 at the base of the second transistor 77, which opens and the first closes, because there is zero potential at its base. Due to the optical signal from the LED 86 of the second. bit 85o 2 the second photo thyristor 88 of this bit goes into the conducting state. With the arrival of the second pulse, the second photothyristor is locked.

88 of the second bit 85.2, and the second photothyristor 88 of the third bit opens, and so on. With the arrival of the eighth pulse, all the second photo thyristors 88 are locked. With the arrival of the fifteenth pulse, the processes described are repeated in a similar way.

In the second mode, on the first input 63, there is O, which arrives at the first inputs of the AND-NE 73 and 74 elements, the first And 70 element and the Inverse of the And 75 element with the inverse input. The AND-NE 73 and 74 elements go to state 1, which are fed to the second inputs of the second and third elements And 71 and 72. At the output of the first element And 70 there is O. At the output of the optoelectric converter 83 there is 1, which is fed to the first inputs of the second and third elements And 71 and 72. Transistors 76 and 77 open, from input 68 to input 89 of the trigger setup 69 enters short This impulse sets it to the zero state. A positive pulse is applied to input 67 of register 18. The triggering LED 81 supplies an optical signal to the triggering photo thyristor 82, unlocking its Current will flow from the power supply bus, a resistor 80, a first discharge LED 85.1 85.1 and the triggering photo thyristor 82 to the first output of the trigger 69. From the input 65 to the count-

The first input 90 receives pulses with a period of 1 s. Trigger 69 begins to switch.

With the arrival of the first pulse, the first photo-thyristor 87 of the second bit 85.2 passes to the conducting state, the LED 86 of which supplies an optical signal to the second photo-thyristor 88 of the same bit. In this case, the current flows from the power supply bus 8 through the collector-emitter junction of the first transistor 76, the second photo thyristor 88 of the second bit 85.2 to the second output 61.2C. The first bit 85.1 is zeroed out, however its second photo thyristor 88 remains in the conducting state . With the arrival of the second pulse, a third bit of 85.3 is excited, and so on. With the arrival of the fourteenth pulse, the fifteenth bit 85.15 is excited, the LED 86 of which supplies light to the input of the optoelectronic converter 83 and the first phototransistor 87 for the first time.

With the arrival of the fifteenth pulse, the last bit 85.15 is zeroed and the first is excited. In the following, the processes are repeated.

Switching modes in register 18 can occur at any time, and there is no malfunction.

Resistors 78 - 80 are needed to set the operating currents in the appropriate circuits.
