集中控制的概念
集(ji)(ji)(ji)中(zhong)控制的概念,包括(kuo)集(ji)(ji)(ji)中(zhong)監(jian)視自動(dong)(dong)門運行狀態(tai)和集(ji)(ji)(ji)中(zhong)操作(zuo)多個自動(dong)(dong)門兩(liang)層含義,集(ji)(ji)(ji)中(zhong)監(jian)視自動(dong)(dong)門開(kai)門關門狀態(tai)可以通過(guo)位(wei)置(zhi)(zhi)信(xin)(xin)(xin)號(hao)(hao)(hao)輸出電路來實(shi)現(xian),可以采用接觸(chu)式開(kai)關,當(dang)門到達一定位(wei)置(zhi)(zhi)(如開(kai)啟位(wei)置(zhi)(zhi))時(shi)(shi),觸(chu)動(dong)(dong)開(kai)關而(er)給出觸(chu)點信(xin)(xin)(xin)號(hao)(hao)(hao)。也(ye)可以采用感應式信(xin)(xin)(xin)號(hao)(hao)(hao)發生裝置(zhi)(zhi),當(dang)感應器探測到門處于某一位(wei)置(zhi)(zhi)時(shi)(shi)發出信(xin)(xin)(xin)號(hao)(hao)(hao)。在中(zhong)控室設置(zhi)(zhi)相應的指(zhi)示(shi)燈,就可以顯示(shi)自動(dong)(dong)門的狀態(tai),而(er)集(ji)(ji)(ji)中(zhong)操作(zuo)通常指(zhi)同時(shi)(shi)將(jiang)多個門打開(kai)或鎖住。
