Abstract
Inventia se refera la un convertor analog-numeric, care prelucreaza diferenta a doua tensiuni, facînd parte din circuitele elementelor de automatizare care dau un semnal de iesire functie de marimea de abatere (eroare). Convertorul este alcatuit dintr-un generator de curent constant, care încarca un condensator, generînd o tensiune liniar variabila la închiderea unui întrerupator la aparitia semnalului logic U indice DC de declansare a conversiei, tensiune liniar variabila ce este comparata cu doua tensiuni, una de referinta U indice r, cealalta de masura U indice M, astfel încît, în raport cu relatia dintre ele, sa fie saturat unul din tranzistoarele a doua optocuploare 6 si 7, conectate corespunzator în antiparalel, autorizînd în acest fel trecerea impulsurilor unui generator de tact 11, prin intermediul uneia din cele doua porti logice 9 si 10 afectate optocuploarelor, spre una din intrarile de numarare în sus sau de numarare în jos ale unui numarator reversibil 12.The invention relates to an analogue-to-digital converter, which processes the difference of two voltages, being part of the circuits of the automation elements which give an output signal depending on the magnitude of the error (error). The converter consists of a constant current generator which loads a capacitor generating a variable linear voltage at the closing of a switch at the occurrence of the logic signal U convergence triggering DC, variable voltage voltage that is compared with two voltages, a reference one U index r, the other measure U index M such that, in relation to the relationship between them, one of the transistors of the second optocouplers 6 and 7, properly connected in the antiparallel, is saturated, thus allowing the passage of the impulses of a clock generator 11 via one of the two logic gates 9 and 10 affected by the optocouplers, to one of the counting up or down counting of a reversible counter 12.
