SYS68K/PIO-1 FORCE熱敏電阻前置擴(kuò)展電路規(guī)劃

　　規(guī)劃熱敏電阻前置擴(kuò)展電路如圖3所示。U14為將+5 V轉(zhuǎn)變?yōu)?2．5 V的高參看電壓源，該參看源有極低的噪聲、低的溫度系數(shù)，減少了該擴(kuò)展電路輸出端因為電源引起的噪聲攪擾。R2、R3、R4和激光器內(nèi)部負(fù)溫度系數(shù)熱敏電阻組成橋式擴(kuò)展電路的4個橋壁，當(dāng)熱敏電阻隨溫度改動阻值發(fā)生改動時，橋壁輸出一個跟從溫度改動的電壓差，擴(kuò)展器輸出的電壓反映的正是擴(kuò)展了的熱敏電阻阻值隨溫度改動情況。

　　熱電制冷（TEC）控制電路規(guī)劃 溫度控制選用的TEC集成控制電路芯片，減少了傳統(tǒng)所選用的積分微分電路，使得規(guī)劃簡略，電路調(diào)試便利，可以直接硬件完結(jié)。其要害控制電路規(guī)劃如圖4所示。

　　芯片引腳IN+為熱敏電阻通過前置擴(kuò)展后的輸出電壓信號，R9和R12為分壓電阻，為引腳IN-供應(yīng)一個安穩(wěn)的電壓。引腳IN+端輸入電壓與引腳IN-端電壓進(jìn)行比較，當(dāng)IN+端電壓引腳大于IN-端引腳時，由該芯片資料知輸出為制冷形式，反之為制熱形式。該電路通過負(fù)溫度系數(shù)熱敏電阻輸入端電壓大小來控制整個反響環(huán)路，當(dāng)溫度升高時熱敏電阻阻值減小，由圖3知，熱敏電阻端電壓下降，使得OPA1177輸出比較電壓升高，從而使輸入到DRV953的IN+ 端電壓升高，當(dāng)該電壓大于IN-端相電壓時，使得該芯片輸出電壓翻轉(zhuǎn)控制激光器半導(dǎo)體制冷器由制熱形式轉(zhuǎn)變?yōu)橹评湫问?，通過這樣一個負(fù)反響網(wǎng)絡(luò)完結(jié)溫度自動控制。同理，當(dāng)溫度下降時相同遵從該負(fù)反響原理。
