Visualization Of Controlling Interface For Vacuum System

Applied vacuum system is commonly composed of various vacuum pumps, valves, and pipelines.It provides the vacuum condition needed. The performance of the system greatly lies on its controlling parts to same extent.The purpose of this paper is to develop an universal and graphic controlling interface. This interface can make the pumping system operation more convenient and safer, for it can not only give machine operators a vivid and simple layout of the pumping system with necessary parameters, but also let them control the system by computer mouse clicking. By certain logical restrictions of the system, operators can start and stop corresponding devices correctly, and if an accident happens, for example, electricity breakdown, the developed controlling system should give an alarm, and then protect the system automatically. The applied pumping system equipped with this controlling interface can be easily and safely manipulated. The process parameters of the system can be also showed clearly on the interface.The paper discusses the evolution of vacuum controlling system and the present development of visual controlling interface for vacuum pumping system, and briefly introduces the characteristics of the software Visual C++, which is used to develop the interface. The emphasis is put on the development of a visual controlling interface for various pumping systems. An editor is developed, in which a desired visual controlling interface for a real pumping system can be edited easily, The key code is programmed and tested. The hardwares needed for realization of the visual control of the applied pumping system are selected, and related electrical circuits are designed. The paper ends with a demonstration of a typical vacuum pumping system to interpret the realization of the control of the system by visual controlling interface.
