Abstract

Визначено та обґрунтовано основні вимоги до вимірювальної системи на базі сучасних комп'ютерних технологій. Розглянуто питання побудови вимірювального комплексу апаратно-програмних засобів для проведення вимірювання та побудови графіків диференційного розподілу пор у шкіряних виробах із використанням комп’ютерних технологій.

The aim of this article is the definition and justification of the main measuring system requirements on the basis of modern computer technologies. The basic measuring parameter is the change of pressure in the experimental facility in the course of time. The research was carried out by observing the change of pressure measured by a manometer with simultaneous timing. A complete change of pressure in the chamber with the prototype has occurred in a short period of time, so it was impossible to record the value of pressure. This limited the nomenclature of the research samples. To improve the accuracy of the research values determination, the experimental facility was supplemented by a computer measuring system, which could precisely determine the decrease of pressure in time during the research. The structure of the automatized system for the measurement of pore distribution in leather products is proposed and substantiated. It is experimentally proved that the measurement system allows to record experimental signals, to create the required text file and to exercise further information processing with a standard software. The developed measurement system can be used with a desktop computer and laptop, which extends the scope of its use. Preliminary operation confirmed, the efficiency of the measuring system functioning; the validity of the assumptions and technical solutions regarding the proposed system structure and the processing methods of the received information.
