Abstract
Inventia se refera la automatica si tehnica de masurare, precum si la tehnica de recunoastere a imaginilor si poate fi utilizata in sistemele de control si inregistrare a semnalelor, primite de la senzori de informatie telemetrica, in robototehnica, in tehnica de comunicatii, in tehnica medicala la observarea si controlul parametrilor fiziologici ai obiectelor biologice etc. Procedeul de convertire analogo-numerica de precizie inalta consta in prelucrarea statistica a valorilor masurate la un semnal de intrare constant, sortarea in crestere a valorilor decimate obtinute, neglijarea celor mai mici si celor mai mari valori si calcularea valorii aritmetice medii a celor ramase. Dispozitivul de convertire analogo-numerica de precizie inalta contine un convertor analogo-digital (1), un comutator (2), un bloc de tratare statistica (3) a valorilor masurate si un port de iesire (4) unite consecutiv. Blocul de prelucrare statistica (3), la randul sau, consta dintr-un dispozitiv de sortare (3.1) si un calculator al valorii medii (3.2). Rezultatul inventiei consta in majorarea preciziei de masurare a semnalului de intrare datorita diminuarii erorii accidentale introduse de mediul de masurare.The invention relates to the automatic measurement and measurement technique, as well as to the image recognition technique and can be used in the systems of control and recording of the signals, received from telemetry information sensors, in robotics, in communications technique, in medical technique. when observing and controlling the physiological parameters of biological objects, etc. The high-precision analog-to-numerical conversion process consists in the statistical processing of the measured values at a constant input signal, the increasing sorting of the obtained decimal values, the neglect of the smallest and highest values and the calculation of the average arithmetic value of the remaining ones. The high precision analog-to-digital conversion device contains an analog-to-digital converter (1), a switch (2), a statistical processing block (3) of the measured values and an output port (4) consecutively linked. The statistical processing block (3), in turn, consists of a sorting device (3.1) and a computer of average value (3.2). The result of the invention consists in increasing the measurement accuracy of the input signal due to the diminution of the accidental error introduced by the measurement environment.
