The Research And Development Of Visual Instrument Based On The Object-Oriented Technique

With the ever-advancing testing requirement in the checking and controlling field and the development in both the electronical techique area and the computer techquice area, the traditional testing instrument increasing cann't meet the demand of the computer time. The traditional instrument is expensive, single-functioned, inadaptable, and low-automationed, and cann't conduct comprehensive analysis and evaluation on the system that is examined, which has:a direct effect on the improvement of testing quality as well as the testing standard. The apparatus, with the specialities such as miniature, automation, flexibility, and individual-computer managing has become the developing trendof the testing equipment today.Based on analysis of the characteristic and the system structure of the visual instrument, the paper has studied the design idea of it, put forward the exploiting methods of the visual instrument based on the object-oriented technique, exoatiated on the technique kernel of design the visual instrument under windows environment, designed a typical visual instrument "VIS-1 signal-analyzing and wave-displaying system", which integrates multi-function instruments such as general oscillograph and ULF oscillograph real-time signal recorder wave and frequency-pedigree analysis instrument .The system has more excellent functions and characteristics than traditional instruments. It has high automation and reliability, a friendly interface. It has better adaptable soft-structure, huge development potential, good maintainability, wide application prospect. It can be applied to many departments which need detect and analyze signals such as science research, teaching, production and medical detecting.
