DIAGNOSTICS OF UPPER AND LOWER AUTOMATION AND TELEMECHANICS SYSTEMS IN RAILWAY TRANSPORT

Abstract

Studied the principles of multifunctional sensors (MFS) physical quantities (PQ), based on different physical effects. The criteria of information and energy and technological compatibility conversion of different values one sensor selected basic methods combined conversion of non-electrical quantities. It is shown that the most advanced and applicable for the automation systems are microelectronic sensors (MES). The structure charts multifunctional sensors with different principles of transformation. The shown models MFS PQ. The proposed classification is physically compatible principles of data conversion of various parameters. Shows concrete implementation examples of semiconductor and piezoelectric MFS PQ.
