Razvoj uporabniškega vmesnika za vodenje kemičnega čiščenja tehnološke odpadne vode

PANDEV, DEJAN (author), Blažič, Sašo (mentor)

V diplomskem delu je opisan razvoj uporabniškega vmesnika za nadzor in krmiljenje naprave za kemično čiščenje odpadne tehnološke vode. Za postavitev čistilne naprave v podjetju Omaplast d.o.o. so se odločili, ker se zavedajo, kako dragoceni so naravni viri. Funkcionalni gradniki, za nadzorn- krmilni sistem so senzorji in aktuatorji, ki izvajajo meritve, regulacije oz. pretvarjajo električne veličine v fizikalne. Zelo pomemben gradnik je programljiv logični krmilnik, ter operaterski panel. Med njima je vzpostavljena medkrmilniška komunikacija. Operaterski panel omogoča vizualen prikaz stanja, kot ga zazna nadzorno-krmilni sistem. Poleg tega pa omogoča še alarmiranje stanj. Aplikacija za nadzor in delovanja procesa je izvedena na operaterskem panelu. Nadzorno-krmilni sistem je zasnovan, tako da je enostaven za uporabnika, ki obratuje 24 ur dnevno in deluje s sprotno obdelavo podatkov. Vse obdelave podatkov na nadzorno-krmilnem sistemu, ki niso sprotne , so zasnovane tako, da ne vplivajo na tekoči nadzor in vodenje procesa in naprav. Med programljivim logičnim krmilnikom in operaterskim panelom je vzpostavljena neprestana komunikacija, ki je pogoj za delovanje celotnega sistema. Komunikacija med programljivim krmilnikom in operaterskim panelom omogoča nastavitev parametrov, potrebnih za normalno delovanje in spremljanje procesa na krmilniku. V primeru izpada komunikacije med krmilnikom in operaterskim panelom, deluje krmilnik neodvisno naprej, pri čemer so uporabljeni zadnji nastavljeni parametri.

• Title: The development of the human-machine interface for the wastewater treatment control system

Abstract

In this thesis is described the system of supervisory-control for waste water treatment. Company Omaplast decided for a wastewater treatment plant because they realize how valuable such natural resources are. Functional elements of supervisory-control system are sensors that perform measurements and regulations, actuators to transform electrical values to mechanical values. Very important elements are programmable logical controller and human-machine interface. Between them is established comminicatio link. Operation panel provides visual status indication and it enables alarm conditions. The application for controlling the operation of the plant is carried out on the operation panel. Supervisory control system has been designed as a system that is easy to use, which is operating 24 hours a day and works with on-line data processing. All the off-line data on the supervisory control system are designed so as not to affect the current control and management of the process and the equipment. Between controller and operation panel communication is established, which is necessary for the functioning of the entire system. Communication between the controller and operation panel provides the possibility to set the parameters required for normal operation and monitoring of this process on the controller. In the event of a failure of communication between the controller and operation panel, controller operates independently and used the last set parameters.
