描述
利用變頻器PG卡輸出端(TA2.1)將脈沖信號引入PLC的高速計數(shù)輸入端0000,構(gòu)成位置反饋。高速計數(shù)器(CNT47)累加的脈沖數(shù)反映電梯的位置。高速計數(shù)器的值不斷地與各信號點對應(yīng)的脈沖數(shù)進行比較,由此判斷電梯的運行距離、換速點、平層電和制動停車點等信號。理論上這種控制方式其平層誤差可在±1個脈沖當(dāng)量范圍。在考慮減速機齒輪嚙合間隙等機械因素情況下,電梯的平層精度可達±5mm內(nèi),大大低于國標(biāo)±15mm的標(biāo)準(zhǔn),滿足電梯起制動平滑,運行平穩(wěn),平層準(zhǔn)確的要求。電梯在運行過程中,通過位置信號檢測,軟件實時計算以下位置信號:電梯所在樓層位置、快速換速點、中速換速點、門區(qū)信號和平層位置信號等。由此省去原來每層在井道中設(shè)置的上述信號檢測裝置,大大減少井道檢測元件和信號連線,降低成本。下面針對在實現(xiàn)集選控制基礎(chǔ)上新增添的樓層計數(shù)、快速換速、中速換速、門區(qū)和平層信號5個子程序進行介紹。
3.1樓層計數(shù)
本設(shè)計采用相對計數(shù)方式。運行前通過自學(xué)習(xí)方式,測出相應(yīng)樓層高度脈沖數(shù),對應(yīng)17層電梯分別存入16個內(nèi)存單元DM06~DM21。
