傳感器校正算法 當(dāng)用最小二乘曲線擬合法擬合函數(shù)時(shí)，如果逼近次數(shù)太高，導(dǎo)致計(jì)算速度過慢時(shí)，就應(yīng)當(dāng)采用分段曲線擬合。其原理是：對傳感器分段選擇多個(gè)試驗(yàn)點(diǎn)進(jìn)行精確測試，并根據(jù)測試數(shù)據(jù)繪制出傳感器的各段擬合曲線，然后利用擬合函數(shù)產(chǎn)生校正值生成分段查找表。如利用Kingview提供的工具直接查表取值，顯然將會影響測量精度。如果采用線性插值的分段處理方法，必能有效提高系統(tǒng)精度，所以綜合應(yīng)用函數(shù)分段擬合算法和線性插值將會有效提高系統(tǒng)的測量精度。利用線性插值法實(shí)現(xiàn)補(bǔ)償?shù)倪^程是首先確定測量值在哪一個(gè)區(qū)間，然后調(diào)出區(qū)間端點(diǎn)對應(yīng)值，利用公式：
實(shí)現(xiàn)校正，其中M為測量輸出值，（M1，P1）、（M2，P2）為區(qū)間端點(diǎn)的值。
PLC的機(jī)翼精加工水平測控系統(tǒng)可以根據(jù)不同的工藝參數(shù)對測量位置實(shí)時(shí)監(jiān)控及工藝人員可以通過友好的HMI方便地設(shè)定和修改各種工藝參數(shù)。該系統(tǒng)主要具備下列功能：（1）基本信息顯示功能：顯示各點(diǎn)的基本信息（橫坐標(biāo)、縱坐標(biāo)、校零位等）;（2）工藝參數(shù)配置和修改功能：設(shè)定和修改各點(diǎn)變量（如局部外形偏差、安裝誤差、左右高度差等）的最佳值;（3）實(shí)時(shí)/歷史曲線顯示功能：本系統(tǒng)將所測各點(diǎn)參量實(shí)時(shí)地存入到對應(yīng)的Excel數(shù)據(jù)庫，并在兩類HMI上顯示實(shí)時(shí)/歷史曲線;（4）報(bào)警功能：對系統(tǒng)的通訊點(diǎn)和各點(diǎn)的偏差設(shè)置了報(bào)警功能，一旦達(dá)到這些因素極限，HMI都會發(fā)出報(bào)警信息通知用戶;（5）報(bào)表功能：數(shù)據(jù)報(bào)表主要反應(yīng)生產(chǎn)過程中的數(shù)據(jù)和狀態(tài)等，通過對長期生產(chǎn)過程進(jìn)行統(tǒng)計(jì)可以掌握和分析設(shè)備的生產(chǎn)情況;（6）手/自動(dòng)切換功能：在設(shè)計(jì)電路部分實(shí)現(xiàn)手動(dòng)、半自動(dòng)、全自動(dòng)方式，能實(shí)現(xiàn)監(jiān)控系統(tǒng)的自動(dòng)/半自動(dòng)，手動(dòng)操作模式間的無擾切換;
