旋轉(zhuǎn)門起源于荷蘭，至今已有一百年的歷史，在這段時(shí)間內(nèi)，從以前意義的專門到今天的全自動(dòng)旋轉(zhuǎn)門，旋轉(zhuǎn)門經(jīng)歷了一個(gè)漫長的發(fā)展歷史。其種類較多，按控制方式可分為全自動(dòng)旋轉(zhuǎn)門、半自動(dòng)旋轉(zhuǎn)門和手動(dòng)旋轉(zhuǎn)門；按旋轉(zhuǎn)翼結(jié)構(gòu)方式可分為兩翼旋轉(zhuǎn)門、三翼旋轉(zhuǎn)門和四翼旋轉(zhuǎn)門；按結(jié)構(gòu)材料科分為金屬框架旋轉(zhuǎn)門、水晶旋轉(zhuǎn)門和木旋轉(zhuǎn)門。
國外自動(dòng)旋轉(zhuǎn)門發(fā)展較早。器技術(shù)也較為成熟。自動(dòng)旋轉(zhuǎn)門的傳動(dòng)系統(tǒng)技術(shù)具有節(jié)能、低噪音、傳動(dòng)平穩(wěn)、壽命長、性能可靠等優(yōu)點(diǎn)；控制系統(tǒng)采用數(shù)字化設(shè)計(jì)的系統(tǒng)作為控制中樞，有功能更強(qiáng)大，操作更簡便等優(yōu)點(diǎn)；檢測安全系統(tǒng)采用先進(jìn)的紅外與微波感應(yīng)技術(shù)，用于感知物體的移動(dòng)，操縱門體的運(yùn)行，使用各種安全檢測傳感器，實(shí)現(xiàn)防夾、防撞、防碰功能。與此同時(shí)某些廠家生產(chǎn)的自動(dòng)旋轉(zhuǎn)門還具有遠(yuǎn)程控制和液晶顯示功能。
新中國成立以來，特別是改革開放以后，旋轉(zhuǎn)門也大量的出現(xiàn)在我國的各種公共和高檔場合。在我們高樓聳立的大都市，在大廈、賓館、酒店、銀行、商場、寫字樓，自動(dòng)門已經(jīng)是隨處可見。自動(dòng)門不但能給我們帶來人員進(jìn)出方便、節(jié)約空調(diào)能源、防風(fēng)、防塵、降低噪音等好處，更令我們的大門增添了不少高貴典雅的氣息。
自動(dòng)旋轉(zhuǎn)門是樓宇設(shè)備中的光機(jī)電一體化技術(shù)產(chǎn)品，它給人以親切大方的感覺，同時(shí)營造出奢華的氣氛，其全新的概念，寬敞的開放門面和高格調(diào)的設(shè)計(jì)，堪稱建筑物的點(diǎn)睛之筆，立足于建筑時(shí)代大潮的最前端。大廈在需要持續(xù)不斷的人流出入的同時(shí)，又要保持建筑物內(nèi)良好的空氣循環(huán)及環(huán)境的優(yōu)美，這是建筑師所遇到的一大難題，而旋轉(zhuǎn)門為大廈提供了理想的解決方案，它可有效地防風(fēng)、防塵和隔音，從而改善了大廈入口附近的環(huán)境。旋轉(zhuǎn)門的最大優(yōu)點(diǎn)在于它"永遠(yuǎn)開門，又永遠(yuǎn)關(guān)門"，即對于行人來說，門總可以打開，可對于建筑物來說門又總是關(guān)著。自動(dòng)旋轉(zhuǎn)門由于其永遠(yuǎn)開啟的同時(shí)又永遠(yuǎn)關(guān)閉的特點(diǎn)，使其動(dòng)態(tài)密封效果較好。因此，自動(dòng)旋轉(zhuǎn)門在功能方面具有獨(dú)特的發(fā)展。
1) 旋轉(zhuǎn)門的定義
旋轉(zhuǎn)門：單扇或多扇沿豎軸轉(zhuǎn)動(dòng)的門叫旋轉(zhuǎn)門。
自動(dòng)旋轉(zhuǎn)門：利用各種控制器、信號控制，實(shí)現(xiàn)單扇或多扇沿豎軸自動(dòng)轉(zhuǎn)動(dòng)和自動(dòng)停止的門叫自動(dòng)旋轉(zhuǎn)門。
自動(dòng)門中的頂級產(chǎn)品，旋轉(zhuǎn)門給人以親切大方的感覺，同時(shí)營造出奢華的氣氛，其寬敞的開放門面和高格調(diào)設(shè)計(jì)，堪稱建筑物的點(diǎn)睛之筆。其全新的概念，無可動(dòng)搖地立足于建筑時(shí)代大潮的最前端。但其高造價(jià)也不是一般人能接受的。
2）自動(dòng)旋轉(zhuǎn)門的結(jié)構(gòu)
傳統(tǒng)的三翼和四翼旋轉(zhuǎn)門就是這種結(jié)構(gòu)，即中心門軸通過軸承機(jī)構(gòu)垂直安裝于地面，三個(gè)或四個(gè)門翼呈發(fā)散式固定在中心門軸上，各門扇之間的角度相等，人在內(nèi)扇之間推動(dòng)（按逆時(shí)針）門扇，就成為一個(gè)手動(dòng)旋轉(zhuǎn)門。中心門軸的上方安裝電動(dòng)機(jī)及其他電氣控制部件，再配以感應(yīng)裝置和安全裝置，就成為自動(dòng)旋轉(zhuǎn)門。這種結(jié)構(gòu)是穩(wěn)定性，使用的可靠性很高，使用壽命長。考慮到旋轉(zhuǎn)門在停止時(shí)一定要密封，所以三翼旋轉(zhuǎn)門的每個(gè)分隔可以容納更多的人，可是門的凈開口的寬度較小。而四翼旋轉(zhuǎn)門的每個(gè)分隔可以容納較少的人，可是門的凈開口寬度卻較大。
但是，這種旋轉(zhuǎn)門門翼與中心軸的固定方式?jīng)Q定了門扇寬度不能太大，所以這種旋轉(zhuǎn)門的直徑最大只有約4M。為了解這一問題，工程師們將中心門軸設(shè)計(jì)成了中間展示室，相對減小了門扇寬度，增加了電機(jī)對門中心的旋轉(zhuǎn)作用力矩，使這種旋轉(zhuǎn)門的最大直徑擴(kuò)大到6M，中間展示室又有很好的裝飾效果。作為通道門的自動(dòng)旋轉(zhuǎn)門還要考慮緊急狀態(tài)時(shí)人員的快速疏散，于是旋轉(zhuǎn)門的門翼要能夠在停電時(shí)手動(dòng)推開，所以帶緊急打開功能的自動(dòng)旋轉(zhuǎn)門采用特制的類似合頁的門體接五金件?？墒钱?dāng)風(fēng)壓很大時(shí)，這種門扇結(jié)構(gòu)容易被風(fēng)吹開。五金件的強(qiáng)度也成為這種自動(dòng)旋轉(zhuǎn)門的主要質(zhì)量問題之一。國際自動(dòng)旋轉(zhuǎn)門生產(chǎn)廠又設(shè)計(jì)了專用的電磁鎖，在斷電時(shí)才使門扇可以被推動(dòng)。
3）自動(dòng)旋轉(zhuǎn)門的性能
大廈在需要持續(xù)不斷的人流出入的同時(shí)，又要保持建筑物內(nèi)良好的空氣循環(huán)及環(huán)境的優(yōu)美，這是建筑師所遇到的一大難題，而旋轉(zhuǎn)門為大廈提供了理想的解決方案，它可有效地防風(fēng)、防塵和隔音，從而改善了大廈入口附近的環(huán)境。旋轉(zhuǎn)門的最大優(yōu)點(diǎn)在于它"永遠(yuǎn)開門，又永遠(yuǎn)關(guān)門"，即對于行人來說，門總可以打開，可對于建筑物來說門又總是關(guān)著。自動(dòng)旋轉(zhuǎn)門由于其永遠(yuǎn)開啟的同時(shí)又永遠(yuǎn)關(guān)閉的特點(diǎn)，使其動(dòng)態(tài)密封效果較好。因此，自動(dòng)旋轉(zhuǎn)門在保安功能方面具有獨(dú)特的發(fā)展，但在人員流量方面自動(dòng)旋轉(zhuǎn)門卻沒有優(yōu)勢，因?yàn)殚T的轉(zhuǎn)速是固定的，每個(gè)門翼之間可容納的人員也是有限的。每種自動(dòng)旋轉(zhuǎn)門都有標(biāo)定的人員流量數(shù)值。
自動(dòng)旋轉(zhuǎn)門由于其永遠(yuǎn)開啟的同時(shí)又永遠(yuǎn)關(guān)閉的特點(diǎn)，使其動(dòng)態(tài)密封效果在經(jīng)常使用的條件下相對于其它兩種自動(dòng)門要好。由于自動(dòng)旋轉(zhuǎn)門的人流量有限，在大型公共場合還是選擇其它兩種自動(dòng)門，畢竟自動(dòng)旋轉(zhuǎn)門的本成較高。通常在自動(dòng)旋轉(zhuǎn)門兩側(cè)另設(shè)自動(dòng)或手動(dòng)平開門，一方面增加通行能力，另一方面當(dāng)自動(dòng)旋轉(zhuǎn)門出現(xiàn)故障時(shí)，不影響人的通過。但是在靜態(tài)密封效果方面，自動(dòng)旋轉(zhuǎn)門遠(yuǎn)不如其它自動(dòng)門，因?yàn)槠溟T體運(yùn)動(dòng)方式?jīng)Q定著只能使用毛條密封。
4) 旋轉(zhuǎn)門在我國的市場前景
隨著我國國民經(jīng)濟(jì)持續(xù)穩(wěn)定地增長，2008年北京申奧成功和WTO的加入。從本世紀(jì)開始，我國進(jìn)入了全面建設(shè)小康社會(huì)的新階段，創(chuàng)造美好生活環(huán)境是裝飾業(yè)發(fā)展的巨大推動(dòng)力。現(xiàn)代城市建筑物裝飾裝修中，將高科技應(yīng)用到建筑物的外觀形象上，使城市建筑的入口體現(xiàn)出智能化。對門的選擇由單一的功用型向個(gè)性化、品位化發(fā)展，旋轉(zhuǎn)門以其全新的概念，寬敞開放的門面和高格調(diào)的設(shè)計(jì)，自然成為當(dāng)代的建筑裝飾的主流，無可質(zhì)疑的必選設(shè)施。堪稱建筑物的點(diǎn)睛之筆。
自動(dòng)旋轉(zhuǎn)門控制系統(tǒng)主要由旋轉(zhuǎn)門、接近傳感器、可編程序控制器和變頻器組成。
1）旋轉(zhuǎn)門及接近傳感器
該旋轉(zhuǎn)門由4扇玻璃門相互垂直地鑲嵌在同一個(gè)軸柱上構(gòu)成，電機(jī)通過減速機(jī)構(gòu)帶動(dòng)旋轉(zhuǎn)門的軸柱，從而產(chǎn)生門的旋轉(zhuǎn)運(yùn)動(dòng)。
為了實(shí)現(xiàn)系統(tǒng)的全部自動(dòng)化和智能化，系統(tǒng)在旋轉(zhuǎn)門圓形框架的上端，安裝了4個(gè)接近傳感器，其中3個(gè)面向進(jìn)門的行人，一個(gè)面向出門的行人；在門框外側(cè)的邊沿上分別安裝了2套防夾傳感器；在圓弧門框外側(cè)的表面上，分別安裝了暫停按鍵和殘疾人專用換速按鍵。
2）可編程控制器PLC
該系統(tǒng)利用三菱公司的FXOS-14MR-001系列PLC，作為該系統(tǒng)的控制指揮中心。該P(yáng)LC把來自旋轉(zhuǎn)門現(xiàn)場的檢測信號、變頻器的狀態(tài)信號以及樓宇自動(dòng)監(jiān)控系統(tǒng)的指令，經(jīng)過收集、處理后，完成對變頻器的頻率控制和對樓宇自動(dòng)監(jiān)控系統(tǒng)的信息反饋。
3）變頻器
? 由于旋轉(zhuǎn)門處于公共場所，行人或物品阻礙旋轉(zhuǎn)門正常旋轉(zhuǎn)的現(xiàn)象時(shí)常發(fā)生，因此導(dǎo)致電動(dòng)機(jī)的負(fù)載變化大、過電流現(xiàn)象發(fā)生頻繁，所以選用通用JP6C-T9-0.75型變頻器。該變頻器具有快速響應(yīng)的電流限制功能，當(dāng)負(fù)載波動(dòng)相當(dāng)大時(shí)，變頻器不跳閘，能自動(dòng)減速運(yùn)行；當(dāng)負(fù)載恢復(fù)正常時(shí)，變頻器能自動(dòng)升速到設(shè)定值。使用該變頻器，電動(dòng)機(jī)低速驅(qū)動(dòng)能力強(qiáng)，起動(dòng)轉(zhuǎn)矩能達(dá)到額定值的150％。該變頻器還具有電壓自整定等一系列先進(jìn)功能。
? 4）旋轉(zhuǎn)門運(yùn)行狀態(tài)診斷程序
?? 樓宇自動(dòng)監(jiān)控系統(tǒng)除了使用攝像機(jī)獲取旋轉(zhuǎn)門的外部工作狀態(tài)信息外，還需要使用PLC獲取旋轉(zhuǎn)門控制系統(tǒng)內(nèi)部的工作狀態(tài)信息。所以在編輯控制系統(tǒng)內(nèi)部狀態(tài)診斷程序時(shí)，不但要照顧到現(xiàn)場維護(hù)人員能利用PLC診斷故障，還照顧到樓宇自動(dòng)監(jiān)控系統(tǒng)準(zhǔn)確、方便地使用PLC提供的診斷信息。
綜上所述，該旋轉(zhuǎn)門設(shè)計(jì)新穎、外觀大方、功能齊全、使用控制方便，，行人所接觸到的按鍵也能夠保證安全。同時(shí)，接近傳感器的可靠性也是實(shí)現(xiàn)旋轉(zhuǎn)門控制系統(tǒng)自動(dòng)化和智能化關(guān)鍵之一。是集機(jī)電于一體化的高新技術(shù)產(chǎn)品。同時(shí)其較好地滿足了廣大用戶的求，擴(kuò)大了PLC和通用變額器的應(yīng)用范圍，提高了旋轉(zhuǎn)門控制系統(tǒng)的自動(dòng)化和智能化程度，深受物業(yè)管理行業(yè)科技人員和維護(hù)人員的青睬。
PLC控制系統(tǒng)硬件設(shè)計(jì)需滿足如下幾個(gè)功能：
(1)自動(dòng)轉(zhuǎn)停功能
來人時(shí)自動(dòng)啟動(dòng)，并以正常轉(zhuǎn)速動(dòng)轉(zhuǎn)，15s時(shí)無人進(jìn)出，則自動(dòng)停轉(zhuǎn)并封門。
(2)殘疾變速功能
旋轉(zhuǎn)門設(shè)有低速，中速，高速三種旋轉(zhuǎn)速度，分別對應(yīng)殘疾，middle和high三個(gè)按鈕進(jìn)行切換，以適應(yīng)殘疾人通過、正常運(yùn)轉(zhuǎn)和緊急疏散對轉(zhuǎn)速的不同要求。30s內(nèi)始終以2r/min的速度低速運(yùn)轉(zhuǎn)，此時(shí)按中速（Middle）和高速（High）無效，以確保殘疾人安全通過。30s后來人，門自動(dòng)以正常速度運(yùn)轉(zhuǎn)。
(3)防夾功能
當(dāng)門扇運(yùn)轉(zhuǎn)靠近曲壁立柱時(shí)，如果行人試圖從兩者之間(防夾區(qū))進(jìn)入旋轉(zhuǎn)門，則門立即自動(dòng)停轉(zhuǎn)以防夾傷行人。行人離開防夾區(qū)，門自動(dòng)恢復(fù)運(yùn)轉(zhuǎn)。
(4)防撞功能
行人緊靠右側(cè)立柱或遇到物體碰撞右側(cè)立柱,則旋轉(zhuǎn)門馬上停轉(zhuǎn)，以防止撞傷行人或撞壞物體，行人或物體離開右側(cè)立柱,自動(dòng)門恢復(fù)運(yùn)轉(zhuǎn)。
(5)防碰功能
行人在旋轉(zhuǎn)門內(nèi)通行過程中，如遇到門扇碰到行人腳后跟，則門立即停轉(zhuǎn)，以防止碰傷行人。行人離開門扇，門自動(dòng)恢復(fù)旋轉(zhuǎn)。
(6)急停功能
當(dāng)出現(xiàn)緊急意外事故十，按下急停按鈕，門立即停轉(zhuǎn)，解除急停信號，門又自動(dòng)恢復(fù)運(yùn)轉(zhuǎn)。
(7)暫停功能(STOP按鈕)
與急停功能相當(dāng)，不同的是按STOP鈕后，必須用殘疾，middle和high三個(gè)按鈕中的一個(gè)進(jìn)行恢復(fù)。
(8)電動(dòng)機(jī)過載保護(hù)功能
當(dāng)電動(dòng)機(jī)過載時(shí)，門停轉(zhuǎn)并且指示燈閃爍報(bào)警。過載消除后門自動(dòng)恢復(fù)運(yùn)轉(zhuǎn)。
(9)變頻器報(bào)警輸出和延時(shí)自動(dòng)復(fù)位功能
當(dāng)變頻器過壓或過流時(shí)，關(guān)閉輸出，門停轉(zhuǎn)并報(bào)警( 指示燈閃爍)，延時(shí)3s自動(dòng)復(fù)位。
1) 最大限度地滿足被控對象的控制要求
充分發(fā)揮PLC的功能，最大限度地滿足被控對象的控制要求，是設(shè)計(jì)PLC控制系統(tǒng)的首要前提，這也是設(shè)計(jì)中最重要的一條原則。這就要求設(shè)計(jì)人員在設(shè)計(jì)前就要深入現(xiàn)場進(jìn)行調(diào)查研究，收集控制現(xiàn)場的資料，收集相關(guān)先進(jìn)的國內(nèi)、國外資料。
2) 保證控制系統(tǒng)的安全可靠
保證PLC控制系統(tǒng)能夠長期安全、可靠、穩(wěn)定運(yùn)行，是設(shè)計(jì)控制系統(tǒng)的重要原則。這就要求設(shè)計(jì)者在系統(tǒng)設(shè)計(jì)、元器件選擇、軟件編程上要全面考慮，以確?？刂葡到y(tǒng)安全可靠。
3）滿足上面條件的前提下，力求使控制系統(tǒng)簡單經(jīng)濟(jì)適用和維修方
在滿足控制要求的前提下，一方面要注意不斷地?cái)U(kuò)大工程的效益，另一方面也要注意不斷地降低工程的成本。這就要求設(shè)計(jì)者不僅應(yīng)該使控制系統(tǒng)簡單、經(jīng)濟(jì)，而且要使控制系統(tǒng)的使用和維護(hù)方便、成本低，不宜盲目追求自動(dòng)化和高指標(biāo)。
4）選擇PLC是要考慮生產(chǎn)和工藝改進(jìn)所需的余量
由于技術(shù)的不斷發(fā)展，控制系統(tǒng)的要求也將會(huì)不斷提高，設(shè)計(jì)時(shí)要適當(dāng)考慮到今后控制系統(tǒng)發(fā)展和完善的需要。這就要求在選擇PLC、輸入/輸出模塊、I/O點(diǎn)數(shù)和內(nèi)存容量時(shí)，要適當(dāng)留有余量，以滿足今后生產(chǎn)的發(fā)展和工藝的改進(jìn)。
PLC有兩種基本的工作狀態(tài)，即運(yùn)行（RUN）狀態(tài)和停止（STOP）狀態(tài)。RUN狀態(tài)是執(zhí)行應(yīng)用程序的狀態(tài)。STOP狀態(tài)一般用于程序的編制、修改和下載。為了使PLC的輸出能夠及時(shí)相應(yīng)可能隨時(shí)變化的輸入信號，用戶程序不是只執(zhí)行一次，而是反復(fù)不斷地重復(fù)執(zhí)行，直至PLC停機(jī)或切換到STOP狀態(tài)，因此PLC采用的是周期循環(huán)掃描工作方式。
一個(gè)掃描周期可分為以下5個(gè)階段：內(nèi)部處理階段、通信服務(wù)階段、輸入采樣階段、程序執(zhí)行階段和輸出刷新階段。CPU對用戶程序的執(zhí)行過程是CPU的循環(huán)掃描過程，并且是采用周期性地集中輸入采樣、集中輸出刷新的方式來完成的。
1）內(nèi)部處理階段
CPU對PLC內(nèi)部的硬件作故障檢查，復(fù)位監(jiān)控定時(shí)等。
2）通信服務(wù)階段
通信服務(wù)階段是掃描周期的信息處理階段，PLC與外圍設(shè)備、編程器、網(wǎng)絡(luò)設(shè)備等進(jìn)行通信，CPU處理從通信端口接收到的信息。
當(dāng)PLC處于STOP狀態(tài)時(shí)，只執(zhí)行以上兩個(gè)階段的操作。當(dāng)PLC處于RUN狀態(tài)時(shí)，還要完成輸入采樣、程序執(zhí)行和輸出刷新階段的操作。
在PLC存儲(chǔ)器中，設(shè)置了一片區(qū)域用來存放輸入信號和輸出信號的狀態(tài)，它們分別稱為輸入映像寄存器和輸出映像寄存器。PLC梯形圖中的其他編程軟件也有對應(yīng)的映像存儲(chǔ)區(qū)，它們統(tǒng)稱為元件映像寄存器。
3）輸入采樣（輸入處理）階段
每次掃描周期開始時(shí)，先讀取輸入端子的當(dāng)前值，然后寫到輸入映像寄存器中。在隨后的用戶程序執(zhí)行的過程中，CPU訪問輸入映像寄存器，而非讀取輸入端子的狀態(tài)，通常要求輸入信號有足夠的脈沖寬度，才能被相應(yīng)。
4）程序執(zhí)行階段
用戶程序執(zhí)行階段，PLC按照梯形圖的順序，自左而右、自上而下地逐步掃描，在這一階段中，CPU從用戶程序的第一條指令開始執(zhí)行直到最后一條指令結(jié)束，程序運(yùn)行結(jié)果放入輸出映像寄存器和其他軟元件映像寄存器中。CPU逐條解釋并執(zhí)行用戶程序。在此階段，允許對數(shù)字量I/O指令和不設(shè)置數(shù)字濾波的模擬量I/O指令進(jìn)行處理，在掃描周期的各個(gè)部分，均可對中斷事件進(jìn)行響應(yīng)。
5）輸出刷新（輸出處理）階段
每個(gè)掃描周期結(jié)束時(shí)，CPU先把存在輸出映像寄存器中的數(shù)據(jù)寫入輸出鎖存器中。再輸出到數(shù)字量輸出端子，以更新輸出狀態(tài)。然后PLC進(jìn)入下一個(gè)循環(huán)周期，重新執(zhí)行輸入采樣階段，周而復(fù)始。
綜上所述，在輸入處理階段，PLC把所有外部輸入電路的接通/斷開狀態(tài)讀入輸入映像寄存器。外接的輸入觸電接通時(shí)，對應(yīng)的輸入映像寄存器為“1”狀態(tài)，梯形圖中對應(yīng)的輸入繼電器的常開觸點(diǎn)接通，常閉觸點(diǎn)斷開。外接的輸入觸點(diǎn)電路斷開時(shí)，對應(yīng)的輸入映像寄存器為“0”狀態(tài)，梯形圖中對應(yīng)的輸入繼電器的常開觸點(diǎn)斷開，常閉觸點(diǎn)接通。在程序執(zhí)行階段，即使外部輸入信號的狀態(tài)發(fā)生了改變，輸入映像寄存器的狀態(tài)也不會(huì)隨之而變，輸入信號變化了的狀態(tài)只可能在下一個(gè)掃描周期的輸入處理階段被讀入。PLC的用戶程序由若干條指令組成，指令在存儲(chǔ)器中按步序號順序排列。在沒有跳轉(zhuǎn)指令時(shí)，CPU從第一條指令開始，逐條順序地執(zhí)行用戶程序，直到用戶程序結(jié)束為止。在執(zhí)行指令時(shí)，從輸入映像寄存器或其他元件映像寄存器中將有關(guān)編程軟件的0/1狀態(tài)讀出來，并根據(jù)指令的要求執(zhí)行相應(yīng)的邏輯運(yùn)算，運(yùn)算的結(jié)果寫入到對應(yīng)的元件映像寄存器中。因此，各編程元件的映像寄存器的內(nèi)容會(huì)隨著程序的執(zhí)行而變化。在輸出處理階段，CPU將輸入映像寄存器的0/1狀態(tài)傳送到輸出鎖存器。梯形圖中某一輸出繼電器的線圈“通電”時(shí)，對應(yīng)的輸出映像寄存器為“1”狀態(tài)。上面某一編程軟件（如輸入繼電器、輸出繼電器）對應(yīng)的映像寄存器為“1”狀態(tài)時(shí)，稱該編程元件為ON，元件映像寄存器為“0”狀態(tài)時(shí)，稱該編程元件為OFF。信號經(jīng)輸出模塊隔離和功率放大后，繼電器型輸出模塊中對應(yīng)的硬件繼電器的線圈通電，其常開觸點(diǎn)閉合，使外部負(fù)載通電工作。如果梯形圖中輸出繼電器的線圈“斷電”，對應(yīng)的輸出映像寄存器為“0”狀態(tài)。在輸出刷新階段之后，繼電器型輸出模塊中對應(yīng)的硬件繼電器的線圈斷電，其常開觸點(diǎn)斷開，外部負(fù)載斷電，停止工作。

Definition of revolving door
The revolving door: single sash or more along the vertical axis rotation of door of door that revolving door.
The automatic revolving door: using various controller, signal control, to achieve single fan or more along the vertical shaft automatic door rotation and automatic stop door that the automatic revolving door.
Automatic door of the top product, revolving door give a person with kind and easy feeling, and build a costly atmosphere, its spacious open appearance and high style design, can be called the nods eyeball pen of buildings. The brand new concept, is unswervingly based on the forefront of building age tide. But the high cost also is not the average person can accept.
The automatic revolving door structure
The traditional 3 wing and 4 wing revolving door is the structure, or the central door shaft bearing institutions through installed vertically on the ground, and three or four door wing is fixed in the center spread type door shaft, and the doors, the Angle between the equal, fan (in between push counterclockwise) of the inner sanctuary, became a manual revolving door. The upper part of the shaft center door installation motors and other electrical control components, match again with sensors and safety device, will become automatic revolving door. This structure is stability, the use of high reliability, long service life. Considering the revolving door in stops must seal, so each of the three wing revolving door space can accommodate more people, but the door open net the width of the small. And four wings of the revolving door every space can accommodate less people, but the door is open width is bigger.
But, this kind of rotating central axis wing with double the fixed way that decided the door leaf width can not be too big, so the revolving door of only about 4 M maximum diameter. To understand this problem, engineers will center door shaft design became showroom, reducing the relative among door leaf width, increased the motor in the center of the opposite effect, make the rotating torque of the revolving door the biggest diameter expanded to 6 M, showroom and middle have very good adornment effect. As the door to consider the automatic revolving door emergency personnel's quick evacuation, so the revolving door to door wing during blackout manual push away, so take emergency functions of automatic revolving door open the door of the special similar hinge pick up hardware. But when wind pressure big, this kind of door leaf structure easy to blow away. The strength of the hardware that has become the automatic revolving door of the main quality problem. International automatic revolving door factories and design the dedicated electromagnetic locks, in case of a power cut just made can be promoting.
The performance of the automatic revolving door
Building on the need to keep people in and out at the same time, they keep building good air circulation and the environment is beautiful, it is the architect met a big problem for the building, and the revolving door provide the ideal solution, it can effectively wind, dustproof and sound insulation, thus improving the building near the entrance to the environment. The greatest advantage of the revolving door is that it "forever and ever close the door open the door," which means that, for pedestrians, it always can open the door to door for buildings, and are always closed. The automatic revolving door because its always open at the same time, the characteristics of the closed forever, make its dynamic sealed effect is good. Therefore, the automatic revolving door in the security has distinctive function of development, but in personnel flow automatic revolving door but not in advantage, because the speed of the door is fixed, every door between wing can hold is limited. Staff Each automatic revolving door have calibration personnel flow numerical.
The automatic revolving door because its always open at the same time never closed its dynamic characteristics and sealing effect under the condition of the often use relative to the other two kinds of automatic door is better. Because of the automatic revolving door for the communities in large public limited, or choose other two kinds of automatic door, after all, the automatic revolving door of this into higher. Usually in the automatic revolving door both sides a manually or automatically even open the door, on the one hand, increase capacity, on the other hand when the automatic revolving door malfunction, do not affect a person to pass. But in static sealing effect, automatic revolving door is much less than the other automatic door, because its door body movement way determines can only use over the tops of seal
Revolving door in our market prospect
