Description

The invention relates to a measurement technique and is intended to evaluate the effects caused by the action of an electromagnetic field on technical and biological systems by parameters of an electromagnetic field.

The purpose of the invention is to improve the accuracy in determining the parameters of the electromagnetic field, which interacted with the object, and also to increase the accuracy in determining the parameters of the electromagnetic field interacting with the object by taking into account interruptions in the action.

The drawing shows a block diagram of a device for determining parameters of an electromagnetic field;

The device for determining the parameters of the electromagnetic field contains a three-component antenna 1, three frequency-weighting units of block 2, three quadrants 3, adder 4, integrator 5, switch 6, indicator 7, comparator 8, key 9, additional integrator 10, functional converter 1I, additional adder 12, an additional comparator 13, as well as a time meter 14 and a dividing unit 15.

The method for determining the parameters of the electrode field is implemented as follows.

The signals from the three-component antenna 1 through three channels consisting of frequency-weighting units 2 and quadrs 3 are summed in an adder. 4 and a signal proportional to the sum of squares is integrated in integrator 5 and through switch 6 enters indicator 7, where the total impact on the object is displayed, which is compared with the allowable value. If necessary, the influence of the reconstructed processes at the moments of interruptions in the action of the electromagnetic field is taken into account. a floor for the objects is entered into a correction block formed by a comparator 8, a key 9, an additional integrator 10, a functional 10

A conversion converter 1 1 to a recovery function (for example, an exponent), the magnitude of which is negative and summed algebraically (i.e., subtracted) with a signal proportional to the cyI maximum influence in additional adder 12. If the total signal at the output of additional adder 12 is less than zero, corresponds to the absence of an electromagnetic field effect or the complete restoration of the object, an additional comparator 13 is triggered and includes a key 9, as a result of which the potential accumulation in the additional integration Ore 10 stops ..

Blocks 13 and 15 serve to estimate the power of exposure. A signal proportional to the cyMMapHOivfy effect on the object is fed to dividing unit 15 and is divided in it by an amount proportional to the duration of time emitted from meter 14 and fed to indicator 7 through a switch 6. The latter connects the indicator 7 to various points of the circuit, which allows the following modes of operation: the first three positions indicate the current value of the power of the action along the orthogonal axes X, Y, Z; the fourth is an indication of the current total power value .. impact; Fifth - indication of the total impact on the object; the sixth is an indication of the total impact on the object, taking into account the restoration; the seventh is an indication of the average power applied to an object, and the reciprocal of it is the predicted time-to-life of the object.

For signaling the power, the signal from the output of the quadrant 3 or the adder 4 can be supplied through 45 through a frequency voltage converter, forming an afterbirth; pulses, on the counter, carried out the summation of these pulses. If the number of pulses for a given period

a transducer 11, an additional 50 times, defined by a timer, a final adder 12, and an extra time. the set value is raised, cleared

The blocking from the control valve, which is turned on at the output of the counter, and the sital through it from the generator through force / gel power is fed to the handset and (or) the light emitter and the signal sounds. When the next specified number of pulses is recalled, the signal repeats and sounds again as a signal commander 13. In cases when the signal level at the output of the adder 4 does not exceed a certain fixed level, the key 9 is triggered, through which the constant voltage goes to the input of the additional integrator 10, where a potential is accumulated that is transformed
