REALIZATION OF CHOSEN FUNCTIONS FOR DIGNOSTIC NETWORK SYSTEM OF ELECTRICAL DRIVES

The fault detection and diagnosis in drive systems has practical great significance. Modern non- invasive diagnostics of induction cage motors usually bases on Fourier spectra of stator currents. Creation of individual diagnostic system for one specific motor is very expensive. This problem can be transfer to specialized Diagnostic Center. The aim of this center is to provide detection and diagnosis damage in motors as such outsourcing service. For realization diagnostic applications, Diagnostic Center provide for a specialized data-base. Information can be analyzed in this center by expert systems and faults can be detected before they lead to a partial or total failure of the machine. It requires of installation suitable equipments for remount control measurements and data acquisition in industrial plant. That system offers advantages like: reduction of costs measure and data collection, immediate data delivery and independence from distance to measured object. In this paper, we propose a distributed tele-measuring system supporting Diagnostic Center. As for data transmission, Internet and industrial Ethernet net is used as inexpensive link.
