Monitoring, Recording and Diagnosis Designed Hardware Structure for a Data Acquisition Module Running in Electro-energetic Environment

Abstract

Applications for monitoring, recording and diagnosis in electro-energetics settle as objective the safety increase in exploitation, for installation and for equipment as well, through fast failure detection and preventing critical situations. This specific area of applications implies the design and implementation for an industrial environment acquisition module with several basic technical features: allowing the acquisition of a minimum of 8 analog electrical signals, with settable parameters, providing synchronous sampling for all inputs and also 14 or 16-bit resolution for analog-to-digital conversion, assuring temporary data storing and on-request transfer to a computer for database saving. The data acquisition unit functionality is managed through a firmware, launched automatically when powered on. The module provides the required data acquisition information for further data processing, complex functioning regimes and voluntarily generated phenomena analysis specific to electro-energetic installations. This presented data acquisition module has an open structure, in terms of hardware architecture and also as resource storage for local processing and communication, thus being seen as an optimal solution.
