(54) DEVICE FOR DETERMINING THE TIME OF MACHINE WORK

one

The invention relates to devices for determining the characteristics of electrical signals, and can be used in automation, electrical engineering, electrical engineering (for example, for determining loads, vibrations, mining machines) and other aspects of the national economy.

Identity: a device for determining machine loads, which contains comparators, voltage detrap, resistors, coulometers, and diodes.

The disadvantage of it is a significant error of indication (12 -t 15%).

The object of the invention is to create a reliable and simple device for detecting the law of the propagation of electrical signals in a differential form with a readability of no more than 6–8%.

This goal is achieved due to the fact that in the device (consisting of comparators, resistors, cloop meters, diodes and a source of stabilized power, a resistor and a coulometer are connected to the output of each comparator, the second circuit

is connected through a diode to the output of the SCM-dx go KOMnapaixjpa,

In the absence of voltage at the input (J (t), the voltage at the outputs of the K-K rators is absent and, the investigator, the current through the Q-meter. The O. does not pass. When the input appears of the device, the value of L (t) and the achievement of a greater magnitude, and the voltage supplied from the voltage divider to the input of the K-coder K output voltage appears at the output of the latter, and the current starts to flow through the coulometer. voltage divider at the input | .о; lp r 1tora K at input G of the next to: c 1; the same voltage as at the output.

Thus, each coulometer shows the duration of the input signal L / (t) with levels corresponding to the adopted steps of the voltage divider, which gives the distribution law and (t) of the signal being analyzed in a differential form. Since the voltage values at the outputs of the comparators may differ somewhat from each other, so that the differences in voltages do not affect the readings of the coulometers, the diodes D, Dd are in the circuit. Comparators, one of the inputs of which are connected to a power source connected to a voltage divider on resistors, are connected to ly at D1,) uch:) to the input of corresponding comparators, coulometers, diodes and resisto | e e with TeNf that, with lel ov1L1peni accuracy whisker; troystva, it you move kazhdsho comparator via a series connected resistor - coulometer and a diode connected to the output of subsequent br inei-o KOMriapMf ora.
