the output of the imaging unit 24 is connected to the second input of the OR element 23, the output of which is connected to the reset inputs of the counter 21 and the delay elements 11 and 12 of the first 9 and second 10 channels, the information inputs of which are connected to the outputs of the counters 4 and 5 of the time reference block, the output of the node 6 control of which is connected to the installation inputs of counters 13 and 14,

The inputs of the generator 19 and / or the pulse amplifier 20 with an electromagnetic device are connected to the output of a matching element 18 via switching elements 28. and 29.

The device works as follows.

The current time information generated by the device is encoded as follows. The dial of an ordinary clock is divided into four sectors (Fig. 2a). When reading information about the hours or minutes, the device generates at the output a number of pulses that is equal to the sector number in which the current 1 hour or hour (imaginary) hand is. After a pause, the device generates pulses, the number of which corresponds to the number 1/3 of the sector (FIG. 2). As a result, a sequence of pulses is formed at the output of the device, supplying consumers with information about the current time, the cohort of giving information about the number of hours equal to 0, and about the number of minutes does not exceed 5 minutes.

Consider the operation of the device on the example of obtaining information about the minutes of a long time.

When button 7 is pressed (produced by time signals at the beginning of the hour to correct the hours), counters 13 and 14 are zeroed and begin to receive information. Pulses with a period of 5 minutes through element 12 are applied to counter 14, which is triggered by a positive edge of pulses at the counting input. Counters 13 and 14 are constructed so that their zeroing occurs immediately after the appearance of single signals on all output buses. By briefly pressing the button 26, the shaper 22 forms a positive differential, which, through element 23, permits the passage of second pulses from the clock to the input

21 and the entries of the elements 17 and 13. The code 8 of the counter 21 performs the switching of the multiplexer 15, and a sequence of pulses appears at the output (it determines the sector number and its parts. After the eighth second pulse arrives, the negative difference from the high bit of the counter 21 is fed on the trailing edge driver 25 and returns the driver 22 to its original position. When this is done, the counter 21, elements 11 and 12 and the multiplexer 16 are blocked,

The pulse sequences generated at the output of the device by pressing buttons 27 (Fig. 3) and 26 (Fig. 3.) correspond to the current time of 8 h 53 min. As can be seen from FIG. 3, the maximum measurement time Tj ,, is 8s.
