Abstract

Ineventia se refera la o metoda si un sistem destinate cresterii sigurantei în functionare a sistemelor de calculatoare de proces cu aplicare în toate ramurile industriale, care necesita o conducere în conditii de foarte mare siguranta în functionare, conjugata cu o siguranta la defectare ridicata si eficienta economica. Inventia rezolva aceste probleme, grupând calculatoarele de proces pe zone si sectiuni de proces si asociind fiecarei grupe de calculatoare câte un calculator de proces de rezerva capabil sa preia la defectarea oricarui calculator de proces din grupa, în mod automat, toate functiunile de comanda a procesului de catre calculatorul defect, asigurându-se, totodata, pe perioada comutarii si în lipsa, sau la epuizarea rezervei, semnale prestabilite de comanda în proces logice si/sau analogice catre sectiunile de proces afectate. Inventia este eficienta economic, realizeaza un raport performanta/cost de 4...5 ori mai mare decât procedeele cunoscute, asigurând în permanenta siguranta la defectare si robustete sistemelor de calculatoare de proces.Ineventia refers to a method and a system designed to increase the operational safety of process computer systems with application in all industrial branches which require a driving in very safe operating conditions coupled with a high failure safety and economic efficiency . The invention solves these problems by grouping process computers into process areas and sections and associating each computer group with a backup processor computer capable of defecting any processor computer in the group automatically all the process control functions by the defective computer, ensuring, at the same time, during the switching and in the absence, or at the exhaustion of the reserve, signals predetermined by the logical and / or analogous command to the affected process sections. The invention is economically efficient, it achieves a performance / cost ratio of 4 ... 5 times higher than the known processes, ensuring permanently the reliability and robustness of the process computer systems.
