Description

The known automatic systems of the unified BpeiMeHH, containing a time signal receiver with a selector, a communication channel and a synchronous secondary clock, are not intended to connect any secondary clock and time components.

The proposed system is distinguished by the fact that the independent primary clock is parallel to the translator of informational pulse pulses through the control unit associated with the selector and receiver of the exact time signal, and processing the corrective information impulse transmitter associated with a selector and a communication channel and operating at a frequency different from the frequency of the translator of informational pulse pulses. This feature of the system allows to increase the reliability and accuracy of its operation.

The drawing shows a block diagram of the “Sevan.

Independent iermic clocks 1 form second imulses delivered to the 2 second impulse transponder and control unit 3. Unit 3 is also connected to receiver 4 and selector 5. The latter, in turn, being connected to the receiver output, selects from the set of incoming signals from the receiver a time stamp corresponding to the full hour, and outputs it to control unit 3 and the translator 6 impulse correction. Unit 3 ensures that the receiver is turned on.

4 m of the selector 5 immediately before the sessions of receiving radio signals of the exact time and turning off these objects after working out the signal selector corresponding to the full hour of the exact time, as well as generating

own correction signals in case of failure of the signal from the selector or receiver, for example, due to their exit from the build.

The 2 second pulse generator forms, from the second pulse, coming from the primary clock, high-frequency signals outputted through the attachment device 7 to the communication channel 8 to which the secondary clock is connected. In the correction pulse translator 6, high-frequency signals are formed, corresponding to the clock correction pulses output to the communication link 8 through the connecting device 9. The operating frequencies of the translators 2 and 6 are different. Any wire line can be used as a communication channel (power distribution network, telephone, telegraph, radio transmission and other lines). In this embodiment, the communication channel

network, because in this case, the secondary clock II receives both information signals transmitted from translators 2 and 6, and the power supply for any secondary watches and devices, for example, translator 10, synchronous clocks // with an arrow display , impulse hours 12 with an arrow display, synchronized clocks 13, electronic digital clocks 14 and technical time devices 15 (time, program, stamp, etc. clocks).

A translator 10 that converts the signals of a translator of 2 second pulses into control signals is used to connect the existing secondary clock to the Sewei system.

In the case of using telephone, telegraph, radio broadcasting and other channels as a communication channel, power supply for the secondary clock is provided for autonomous sources or having a power distribution network.

The system works as follows.

From an independent, primary clock. Secondary pulses are output to the translator 2 and the control unit 3. Unit 3 operates on the second impulses of the primary clock as secondary clocks with a software mechanism, providing switching on of receiver 4 and selector 5 approximately 5 minutes before the start of transmission of time signals.

The selector 5, selecting the exact time tag from the signals received from the receiver 4, sends it to block 3 to correct the last and translator 6. After the correction signal has been processed, unit 3 turns off the receiver and selector. Due to the fact that the receiver and the selector are turned on immediately before the arrival of accurate time signals, and are turned off immediately after the correction signal has been processed, the probability of false correction signals is significantly reduced. If the correction signal for any reason has not been received at this hour, the receiver and the selector continue to remain on until the next correction signal is received, and block 3, after a corresponding period of time has passed, sends its own correction signal to translator 6.

Translators 2 and 6 send to the communication line 8, respectively, the second and hour high-frequency correction emulsions, which are low-power information signals for all secondary clocks and time devices connected to the communication channel. This achieves an increase in the noise immunity of the system, and also eliminates its negative influence on the radio and measuring equipment connected to the same communication channel, which is observed during the transmission of powerful (non-information) power pulses through it.

The secondary synchronous clock 11 operates on the frequency of the power distribution network. They are corrected hourly by signals from the translator 6. The secondary clock receives 2 second strokes from the translator, and from the translator 6 - correction signals. The frequency of reception of correction signals at different clocks may be different.
