Description

The invention relates to circuitry for measuring time, length or other one-dimensional sections. In the field of control systems with higher precision requirements, in particular in the field of metering accurate time slots, it is known to measure based on, for example, that a desired length segment consists of elementary precision length segments and most often represents an integral multiple thereof.

The methods of measuring one-dimensional sections by means of the circuitry according to the invention are characterized in that the beginning of the measured section is determined by one limit signal and the end of this section is determined by another limit signal so that according to predetermined or continuously determined optimal solutions limit signals from a wider set of signals.

In this case, the wider set of signals preferably consists of one, two or several sequences of limit logical signals, delimiting sections of a predetermined or continuously determined constant or variable length.

This selection of the limit signals is made by means of a logic network consisting of a base unit whose outputs are connected to the outputs of the wiring via the auxiliary logic circuits, the secondary inputs of these circuits being connected to the outputs of the control unit, and selected by signals The selected logic values at the controller outputs release the passage of the limit signals from the basic metering unit through the auxiliary logic circuits to the wiring outputs, while the limit signals at the wiring outputs limit the time, length, or other one-dimensional sections.

For example, the signal at one secondary input passes to the control input of one or more oscillators and causes or stops these oscillations and thus one time sequence of the limit signals at one output <Aj> of this basic unit of measurement A to match the desired function.

The measurement of the length or other one-dimensional sections is accomplished by applying a frequency at a frequency proportional to these length or other one-dimensional sections which control the frequency of the oscillators, frequency dividers and the like applied to the input or multiple input and the basic unit of measurement.

The control unit B consists, for example, of memory circuits whose outputs are connected to the outputs <Bp, <B ₂ >, <B, j>, ..., <Bjj> of this control unit B.

When the outputs of these auxiliary logic circuits are further coupled to the auxiliary inputs or auxiliary multiple inputs of the basic measurement unit A, it has a clearing passage and an effected passage of the StTTTs through the auxiliary logic circuit, for example through the first auxiliary logic circuit. X ^ results in a change in the basic unit of measurement A, for example for a limited time or takes the first oscillator whose output is connected to the first output <A? of this basic unit of measurement A.

The sub-input or sub-multiple input of the control unit B is, for example, a summary input for all memory circuits, for example an input for resetting these memory circuits to a preselected default state and the like.

Auxiliary Logic Circuits represent a gate with input x, output X, and control input ζ, Fig. 4, where the selected logic signal on the control input opens the passage for the selected logic signal from input x to output · <Χ> gate X;

In the simplest case, the desired section is measured starting from the selected state or time point, for example, an initial state signal until the limit signal is passed through the respective auxiliary logic circuit to the wiring output.

For example, in such a structure and function of the basic measurement, and which at its output <Lo> a sequence signal limit constant length, one section bounded by the signal ^- - initial state and the moment of switching the first cutoff signal through the opened logic Xj from the input x? to <Xj>.

V ^- time transition limit signal output <Xj> occur simultaneously the signal to one input of the control unit B, and causes a change of ^- its state, such as termination of signal selected logicF? values at the output <Bp, thereby closing the auxiliary logic circuit Xj to pass the next threshold signal.

The signal at the first input or other input of control unit B generally causes a change in its state, which is manifested by a change in the signals at the outputs of control unit B.

The next time the output <Xj> is connected to the secondary input® ^ of the basic unit of measurement A, at the moment the limit signal is transferred to the output <Xp at the same time, this signal appears at this input and causes the basic unit of measurement A to change. chroonization, formation of another limit signal and the like.

The measurement of the geometric sections is carried out in such a way that at the outputs of the basic unit of measurement the sequences of the limit signals are formed, bounding in the time transformation the geometric sections, for example the sections corresponding to the movement of the material in the production line. The respective transformation can be established and realized by means of position sensors, material presence sensors, optionally by means of a rolling element with a pulse transducer connected to a base unit, which measures the displacement of the product in question in the production line. The resulting geometric sections are then delimited by the output signals in the wiring outputs.

The circuitry for measuring time, length or other one-dimensional sections according to the invention has wide application in the synthesis of more complex automata, especially in production line control systems. In particular, it enables the generation of complex time sequences of control signals with feedback effects, measurement of geometric sections and the like. It finds quite simple and concrete use in the area of measuring lengths in rolling mill rolling.
