本文介紹了一種基于CPLD的溫度采集系統(tǒng)的設(shè)計(jì)方法，設(shè)計(jì)分為溫度采集和LED顯
示兩個(gè)功能模塊。與常用溫度采集系統(tǒng)相比，本設(shè)計(jì)采用高精度數(shù)字溫度傳感器MAX6627與CPLD控制芯片EPM3128ATC144，系統(tǒng)具有較高的準(zhǔn)確性、通用性和靈活性，功能擴(kuò)展后可通過(guò)高速數(shù)據(jù)傳輸接口實(shí)現(xiàn)與PC機(jī)的通信，對(duì)采集數(shù)據(jù)進(jìn)行綜合分析與處理。

Abstract:This paper discusses a method of designing sample temperature data system by complex programmable logic device.The core of the whole system have been divided into two parts:temperature collection, LED display. The temperature collection controller based on complex programmable logic device, this system is based on MAX6627 precise digital temperature sensors report the temperature of a remote sensor and EPM3128ATC144.It
is more accurate mobility and in common use than others.It can communicate with PC when use high speed data transmission interface,then analyze and deal with these dates.
