Designe on Multifunctional Intellectual Temperature Measure Instrument
Abstract: Temperature，as a basic physical quantity，is one of the most universal and important technical parameters. Along with the development of industry，the requirement of measurement of temperature is higher. Further more，the scope of measurement of temperature is wider, so, the technology of measurement must be improved. The multifunctional intellectual temperature measure instrument introduced by the paper is the system of 8051 single-chip microcomputer and conventional measureing component一AD590. The mathematic model is appropriate，and measurement method is easy to be excuted. The electronic components used are anti一jamming，less zero-drift and less temperature-drift. The instrument is convenient and applicabale，it is steady，reliable and so fit to use. At the same time, it has larger scope of measurement and it can be used in many kinds of object measured. It has intellectualized the process[4].The thesis introduces automatical measurement of temperature，including temperature sensor，I/ O of single-chip microcomputer and application software，it can be divided into some parts：It introduces the development of temperature measurement and the development direction of temperature measurement in the future；According to the practical demands, I design corresponding hardware system；The system can realize data acquisition，showing of temperature on-line.I discuss the future of the instrument.
