A device for measuring the shift of time scales refers to a single time system, in particular, to devices for synchronizing time scales of objects or points for which time is limited to performing a synchronization operation, can be used to determine the shift of scales for fast moving objects

The purpose of the invention is to ensure the accuracy of measuring the shift of the time scales of a clock regardless of the propagation time of signals between reference and working hours.

(Fig. 1 shows a block diagram of a device for measuring the shift of time scales

The device measures the shift of the time scales and contains samples: iu clock 1, receiver 2, transmitter 3. working hours 4, transmitter 5, receiver 6, signal separator 7, trigger 8 clock pulses, controlled divider 9, reversible counter 10, recorder 11, the driver 12 of the control signals, comprising the first element AND 13, the second element AND 11. The first trigger 15, the second trigger 16, the third element AND 17, the fourth element L 18 tre.th trigger 19, the fourth trigger 20, first element OR 21, the second element OR 22, the third element L1 PI 23.

A device for measuring the shift of the pa6oiaer time scale as follows.

In the absence of communication between the working and model hours, the first game, the third and fourth triggers 15, 16, 19 and 20 of the driver 12 are in such a position that at the second input of the first and first input of the second elements 13 and 14 are fed resolving potentials and at the second inputs of the third and fourth elements And 17 and 18 resolving potentials are absent. This is the initial state of the device.

When a connection is established between the points of the working and model hours, the pulses of the time scale from the first output of the working hours 4 arrive at the input of the transmitter 5 and are emitted to the point of the model hours. At one time, the signal comes from the first output of the working hours 2 to the input. Installing the reversible counter 10 the initial state, in which the state of its triggers corresponds to a setting of half the duration of a cycle, i.e. 0.5 T. At the model hours point, the pulses are received by receiver 2 and retransmitted by transmitter 3 to the business hours point.

At the model clock point, the time-scale pulses of the model clock 1 are transmitted by the transmitter 3 to the work station point.

hours The receiver 6 receives the transmitted time scale pulses of the exemplary hours and the retransmitted time scale pulses of the working hours,

which enter separator 7.

I la the first output of the separator 7 signals correspond to the translated pulses of the time scale of the model hours, on the second - to the relayed pulses

0 time scales of working hours, which arrive at shaper 12, the task of which is to generate control commands for a reversible time interval meter containing a generator

5–8, a controlled divider 9 and a reversible counter 10, depending on the order of arrival of the indicated signals, which is determined by the amount of shift V of the time scales of the model and working hours.

0The next operation of the device will be considered with reference to the various variants of the magnitude of the shift of the time scales of working and exemplary hours.

0 The broadcast pulse of the time scale of exemplary chss 1 from the first output of the separator 7 is fed to the first input of the first element I 13 and the second input of the third element I 16 and passes through the first

5 And 13 element, to the second input of which the resolving potential is fed from the second output of the second trigger 16, to the input of the first trigger 15 (the output of the third element And 17 does not receive a signal due to the absence of a decisive potential at its second input) in the state, with coorum, a signal is generated at its first output, coming through the third element OR 23 to the first

5 controlled input of controlled divider 9, setting it to direct transmission of generator 8 pulses to the input of reversible counter 10, as well as the signal from the first output of the first trigger 15 passes through the second element OR 22 to the subtracting input of the reperer of the reversible counter 10, which from this moment begins to count down the time interval. Simultaneously, the signal from the first output of the first trigger 15 is fed to the input of the fourth trigger 20, at the output of which the resolving potential is fed to the first input of the fourth element I 18, and the resolving potential is removed from the second input

the second element And 14 served from the second output of the first trigger 15

The relayed impulse of the time scale of the raggich clock 4 from the second output of the separator 7 enters the second inputs of the second and fourth elements AND 14 and 18 and through the fourth element AND 18 to the second input of which the resolving potential is fed, goes to the second input of the direct element OR 21, from the output of which the signal through the second element OR 22 is fed to the input. The reverse of the reversible counter 10, which continues to count down the time interpal n, and simultaneously the signal from the output of the first element OR 21 is fed to the second input of the controlled case 9 bodies, translate it into a pulse generator frequency dividing mode 8N two output on the second AND gate 14 signap fails due to the lack of permissive tentsiapa at its second input

Work of the reversible counter Yuzakan, by the arrival of a pulse at the end of the cycle from the second output of the working hours 4 to the input. Stop of the reversible SCFSUNA 10 The measurement result of the V value is recorded by the register 11

On the other outputs of the imaging unit 12 signals in this case are not formulated.

In this case, the sequence of the signals from the splitter 7 is the following retransmitted pulses of the time scale of the working hours 4 and then the tiansleyroheiner impulses of the time scale of the reference hours 1.

The relayed pulse of the time scale of working hours 4 from the second exit of the separator 7 enters the second inputs of the second and fourth elements I Mi 18 and passes through the second element I 14 to the second input of which the potential of the second output of the first trigger 15 is fed to the second trigger 16 ( the output of the fourth element I 18 does not receive a signal due to the absence of the resolving potential at its second input) the second trigger 16 is set to the state at which the signal is generated at its first output through the third the element OR 22 at the first input of the control unit, the splitter 9, sets it to the direct transfer mode of the generator 8 to the input of the reversible counter 10 and also the signal from the first output of the second trigger 1 b is fed to the summing input Start of the reversing counter 10, which of this moment begins the direct account of the time interval. At the same time, the signal from the first output of the second trigger 16 is fed to the input of the third trigger1 19 on which the resolving potential is formed, which is fed to the first input of its element AND 17 l takhe ubnr-i gc
