ABSTRACT
With the development of electronic technology, the designing technology of three endings manostat checking instrument has made a great improvement and developed fast, not only realized solid state, but appeared with linearity integration manostat checking instrument, three endings fixed manostat checking instrument and so on, the majorworking characteristic has also improved a lot. At the end of 20 century, a perfect function ,high reliability three endings manostat checking instrument was invented which is the same with every kinds of three endings manostat checking instrument of 78/79 series.
A question for discussion of the graduate design is about three endings manostat checking instrument, the core parts of the instrument are AT89c51 singlechip and ADS7816 as well as other periphery circuit and these corresponding meeting orifice. This article adopt singlechip system controlling periphery number tube, through number tube show the date;using AT89c51 singlechip and ADS7816 modulus switch to transmit date. Making use of AT89c51 singlechip and C editor to edit software
Keywords：singlechip, C editor, three endings manostat checking instrument..
