多路數(shù)據(jù)采集系統(tǒng)

摘 要：本系統(tǒng)是一個(gè)八路數(shù)據(jù)采集系統(tǒng)，控制過程利用電阻的串并聯(lián)輸入直流電壓，結(jié)合放大電路，A/D轉(zhuǎn)換電路，單片機(jī)最小控制系統(tǒng)等構(gòu)成閉環(huán)系統(tǒng)。通過采樣將實(shí)際值輸出到單片機(jī)，由單片機(jī)進(jìn)行控制8279，將采樣通道和電壓值相應(yīng)數(shù)據(jù)顯示出來。
關(guān)鍵詞：多路數(shù)據(jù)采集，AT89S51單片機(jī)，模擬信號產(chǎn)生器

Multi-path data collect system

Abstract: This system adopt a octuplex data collect system , control procedure is the change-over circuit making use of resistant series-parallel connection to import direct current pressure , being tied in wedlock enlarging circuit , A/D , monolithic machine minimum navar waits to compose closed cycle system. Actual value is exported to monolithic machine by taking sample , is control 8279 from Single-chip Microcomputer go along, the corresponding with sampling passage and voltage value data display comes out.
Keywords: The multi-path data collect , AT89S51 Single-chip Microcomputer , analog signal produce an implement.
