WIDE-RANGE MULTIFUNCTIONAL DIAGNOSTICS SYSTEM

measurement of physical and mechanical parameters of environment, nondestructive inspection of diagnosed objects. SUBSTANCE: proposed diagnostics system incorporates nanopickup including sensitive element and voltage-to- displacement converter acting on sensitive element. Current output of sensitive element is connected through current amplifier, current-to-voltage converter, band-pass filter and attenuator connected in series to comparator to which another input reference voltage is fed. Comparator is connected through former of feedback voltage to analog adder. Capacitive output of sensitive element is connected through generator of present frequency to frequency discriminator which other input is connected to former of reference frequencies. Discriminator is connected through former of feedback voltage to analog adder which output is connected to voltage-to-displacement converter. Outputs of converter, analog adder and former are connected through proper analog-to-digital converters correspondingly to first, second and third inputs of interface converter which first to sixth outputs are connected correspondingly to filter, attenuator, former, master generator and generator of stimulating effect. Inputs-outputs of interface converter are connected to inputs-outputs of personal computer. Generator of stimulating effect acts on diagnosed object and acoustic or gravitational signal from diagnosed object comes to sensitive element of nanopickup. Technical result lies in raised sensitivity of 105-108 B/g and enlarged range of frequencies from infralow frequency close to 0 to 150 kHz. EFFECT: raised sensitivity and enlarged range of frequencies. 1 cl, 2 dwg
