Conception of a Control Unit for Critical Systems

Sałamaj M.

International Journal of Electronics and Telecommunications

2013

Vol. 59, No. 4

363-368

The article regards critical systems precisely controlled by safety units. A new idea of safety logic microcontroller is proposed. It is built on the basis of the simplest mechanisms and technical solutions. This approach allowed to obtain a complex decision-making and control microsystem, in which the applied mechanisms and solutions increased its reliability. As a result, the proposed control unit proved to be a universal solution, which can be used in any critical system.

New Conception of Safety Logic Microcontroller

Sałamaj M.

International Journal of Electronics and Telecommunications

2012

Vol. 58, No. 4

419-424

In this paper a new conception of safety logic microcontroller (BML) is described, together with its physical hardware realization. The unit has various mechanisms which increase its safety and reliability, so that it can satisfy rigorous requirements of safety-critical systems. Thus, the BML unit uses some untypical and innovative technical solutions. The new approach to safety systems development allowed to propose a new conception. The paper describes also physical realization of small multiprocessor BML unit for management of decision-control systems adopted to critical usage.

Controlling of the operating tool displacement of master-slave system of cardiosurgical telemanipulator

Kinematics analysis of MASTER-SLAVE system of cardiosurgical telemanipulator Robin Heart 1 is presented in this paper. The motion analysis system APAS was used to determine kinematic values. Determination of kinematics of the cardiosurgical telemanipulator allowed to contorol scale values of displacement and possible delays. All measurements were carried out in the Laboratory of Biocybernetics of Foundation for Cardiac Suregry Development, Zabrze.

W ramach pracy przeprowadzono analizę kinematyki telemanipulatora kardiochirurgicznego Robin Heart 1 w układzie MASTER-SLAVE. Do wyznaczenia wielkości kinematycznych wykorzystano system do analizy ruchu APAS. Przeprowadzone badania kinematyki telemanipulatora pozwoliły m.in. na kontrolę przyjętych wielkości skali przemieszenia i ewentualnych opóźnień. Badania zrealizowano w Laboratorium Biocybernetyki Fundacji Rozwoju Kardiochirurgii w Zabrzu.
