The invention relates to computing and can be used in control computing systems.

The aim of the invention is to simplify the time sensor.

FIG. 1 shows a block diagram of a time sensor; in fig. 2 - timing charts of the device. Jq

The time sensor contains a generator of pulses, a counter of 2 pulses, a decoder 3, a divider 4 frequencies, a counter 5 of time, an AND 6 element, a trigger 7, an AND 8-10 elements, a group of 11 15 keys, a read resolution input 12.

The time sensor works as follows.

High-frequency pulses (a sequence of information is changed to the counting a) from the output of the gate 5 times.

Information from the output of the counter 5

Element And 8,9,6, trigger 7 remains in a single state, thereby allowing the passage of the signal to read the current time value.

The time interval t., Between the end of the formation of the inhibit impulse and the pulse front is set to the time interval te, between the moment of the beginning of the formation of the inhibit impulse and the front of the impulse, over which information is changed in the time counter 5.

Consequently, the inhibit pulse for the current time reference period appears only once and reliably blocks the passage of a signal to read the current time value for a time tf + t4, during which

neratora 1 to the input of the counter 2. Signal; the outputs of the counter 2 are fed to the corresponding inputs of the decoder 3, the outputs of which form three sequences of pulses (Fig.26, c, d), shifted relative to each other by the time interval t. The pulses from the first output of the decoder 3 are fed to the counting input of the divider 4 30 frequency, which produces pulses (Fig. 2, d) synchronized with the pulses b from the first output of the decoder 3. At the time when the divider 4 frequency arrives logic level 1 at the first inputs of the elements And 8, 9, 6, the pulse of the sequence b, passed through the element And 8, sets the trigger 7 to zero

time goes to the inputs of the keys 11, which, when the resolution is applied to them as logical 1 (signal to read the current value of 1 time), allow the passage of information from the output of the counter L to the output of the keys 11.

The pulse from the second output of the decoder 3, passed through the element 6, enters the input of the time counter 5 and is calculated. The impulse r from the third output of the decoder 3, having passed through the element 9, sets the trigger 7 into one state, thereby allowing the signal to read the current time value, which arrives at the second input of the element 10 as a logical 1. 5 time gives information about the current time value. At the moment when the logic level O comes to the first 4 frequencies divider, the information on the counter 5 times changes. Element And 8,9,6, trigger 7 remains in a single state, thereby allowing the passage of the signal to read the current time value. The time interval t., Between the end of the formation of the inhibit pulse and the front of the pulse in the time interval te is set between the moment of the beginning of the formation of the inhibit pulse and the pulse front in which the information is changed in the time counter 5.
