Description

I

The invention relates to computing and can be used to signal the health of blocks and various devices.

A device for generating control signals is known, which contains a shift register, to the output of which are connected pending multivibrators connected in series, an amplifier with an output executive relay and signal sources.

However, the known device does not provide sufficient accuracy for monitoring non-phase signals of different frequencies.

The aim of the invention is to improve the accuracy of monitoring non-phase signals of various frequencies.

For this, the lowest frequency signal source is connected to the recording input of the shift register, with the output of each signal source being connected to the forward inputs of the register in order of increasing their output frequencies, and the output of each of the waiting multivibrators is connected via an amplifier to the diodes.

On .fig. 1 shows a circuit diagram of the device; in fig. 2 - time diagrams.

The device contains a matching circuit having several inputs and. made on ferrite-transistor cells in the form of a shift register 1, an expansion circuit consisting of two single-oscillators built on transistors 2, 3, 4, 5, and communication circuits made on resistors 6, 7 and diodes 8, 9, transistor 10 and relay 11.

The coincidence circuit receives monitored signals. The rarest signal is fed to the input of register 1, the remaining signals are used to advance this signal,

moreover, the phases of the signals at the inputs of register 1 are chosen in such a way as to exclude the coincidence of the moments of recording and reading in any cell.

At the output of register 1, the signal is output only when all monitored signals appear.

From the output of register 1, a pulse signal through a resistor 12, a capacitor 13 and a diode 14 is fed to the base of transistor 3 of the first one-oscillator, which performs the functions of expanding the pulse signal to%. At the same time, the operating time of the single vibrator should not exceed the time interval T between the output pulses of the coincidence circuit so that the next trigger pulse is not passed by the single vibrator. The falling edge of the signal from the transistor 3 of the first one-oscillator through the resistor 15, the capacitor 16 and the diode 17 starts the second one-oscillator at time Ta. Signal from transistors

3 and 5 of both single-oscillators, respectively, through diodes 8 and 9 and resistors 6, 7 are fed to the base of transistor 10 and relay 11. When performing the ratios

and the action of all monitored signals serving the register 1, the relay AND is maintained in the on state and generates a control signal.

Thus, the use of a ferrite-transistor coincidence circuit provides the resulting output signal with a non-in-phase arrangement of monitored signals, the use of a single-vibrator connection circuit reduces the response time of the actuator to one period of the minimum monitored frequency when any of the monitored signals disappears, which in turn allows automatic connecting a backup time block to a specialized meter second system with a minimal loss of information x.
