Research Of The Photo-Electric Detecting Experimental Equipment Based On The Virtual Instrumenttal

Along with modern science and technology and complex autocontrol system and the improvement of information handling theory and technology, Photoelectric signal alternated and the technology with detection emerge continuously, Comprehensive automation and the intelligent photoelectric system that get further development, it formed a new science including optical, precise machinery and electronics and computer science optical precise mechanical electron study ( Optomechatronics ). This kind of interdisciplinary edge technology is photoelectric technology. Now, photoelectric technology has been extensive to apply in each field such as industry, agriculture, culture and education, hygiene, defense, research and family life. Therefore photoelectric detection technology is the key and important composition part of photoelectric technology. Photoelectric detection technology is a kind of high new technology of not contacting measurement, it is based on the modern photoelectric devices such as laser , infrared and optical cable, through having quilt for load, the ray radiation of detection object information carries out detection, passes through photoelectric detector to take over ray radiation and changes for telecommunications wail , from input circuit , enlarge to strain the detection circuits such as wave draw useful information, alternate the interface input operation and handling of personal computer again by A/D , show or print finally the export parameters such as quantity or physical quantity that need the geometry of detection object. Therefore photoelectric detection technology is the most important means and one of method of modern detection technology, measure the technology of detection one important develop direction.Testing technology in modern times takes a new route for photoelectricity checking and experiment teaching of sensor lesson. This article introduces photoelectricity checking experimental equipment of an idea based on virtual instrument. It also tells us the whole design and material function of this experimental equipment from the angle of photoelectricity sensor and hoe to deal with the signal. It makes a material introducing of the actual application of the experiment-stage in teaching.
