程序設(shè)計(jì)
利用變頻器PG卡輸出端（TA2.1）將脈沖信號(hào)引入PLC的高速計(jì)數(shù)輸入端0000，構(gòu)成位置反饋。高速計(jì)數(shù)器（CNT47）累加的脈沖數(shù)反映電梯的位置。高速計(jì)數(shù)器的值不斷地與各信號(hào)點(diǎn)對(duì)應(yīng)的脈沖數(shù)進(jìn)行比較，由此判斷電梯的運(yùn)行距離、換速點(diǎn)、平層電和制動(dòng)停車點(diǎn)等信號(hào)。理論上這種控制方式其平層誤差可在±1個(gè)脈沖當(dāng)量范圍。在考慮減速機(jī)齒輪嚙合間隙等機(jī)械因素情況下，電梯的平層精度可達(dá)±5mm內(nèi)，大大低于國標(biāo)±15mm的標(biāo)準(zhǔn)，滿足電梯起制動(dòng)平滑，運(yùn)行平穩(wěn)，平層準(zhǔn)確的要求。電梯在運(yùn)行過程中，通過位置信號(hào)檢測(cè)，軟件實(shí)時(shí)計(jì)算以下位置信號(hào)：電梯所在樓層位置、快速換速點(diǎn)、中速換速點(diǎn)、門區(qū)信號(hào)和平層位置信號(hào)等。由此省去原來每層在井道中設(shè)置的上述信號(hào)檢測(cè)裝置，大大減少井道檢測(cè)元件和信號(hào)連線，降低成本。下面針對(duì)在實(shí)現(xiàn)集選控制基礎(chǔ)上新增添的樓層計(jì)數(shù)、快速換速、中速換速、門區(qū)和平層信號(hào)5個(gè)子程序進(jìn)行介紹。
