Tradition uses PTC orNTC resistance to be using process to there be existing much defects as thetemperature sensor way, supposes that what be detected the temperature has a badaccuracy, systematic reliability is bad, has much difficulties to design, and the cost ofentire system is expensive. To use this method already unable satisfied modernindustry produces the need being hit by the high-accuracy temperature under thecontrol. Use the special temperature transducer could improve the systematic functionof temperature detecting.This article elaborated the high-accuracy temperature having set forth a becauseof special temperature transducer AD590 checks the main body of a booksystematically designing and realizing process. Entire design is included: Use theAD590 temperature transducer to detect the analog temperature, instrumentationamplifier AD620 signal process system, change the analog signal to digital signalcircuit of ADC0804, the AT89C52 MUC system and the power system.Key wordtemperature check systemAD590AT89C52Ⅱ 目 录 摘 要.............................................................ⅠAbstract............................................................Ⅱ目 录.............................................................Ⅲ1 绪论..............................................................11.1简介.......................................................... 21.2 温度控制系统的国内外现状.................
