旋轉門起源于荷蘭，至今已有一百年的歷史，在這段時間內，從以前意義的專門到今天的全自動旋轉門，旋轉門經歷了一個漫長的發(fā)展歷史。其種類較多，按控制方式可分為全自動旋轉門、半自動旋轉門和手動旋轉門；按旋轉翼結構方式可分為兩翼旋轉門、三翼旋轉門和四翼旋轉門；按結構材料科分為金屬框架旋轉門、水晶旋轉門和木旋轉門。
國外自動旋轉門發(fā)展較早。器技術也較為成熟。自動旋轉門的傳動系統技術具有節(jié)能、低噪音、傳動平穩(wěn)、壽命長、性能可靠等優(yōu)點；控制系統采用數字化設計的系統作為控制中樞，有功能更強大，操作更簡便等優(yōu)點；檢測安全系統采用先進的紅外與微波感應技術，用于感知物體的移動，操縱門體的運行，使用各種安全檢測傳感器，實現防夾、防撞、防碰功能。與此同時某些廠家生產的自動旋轉門還具有遠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，旋轉門也大量的出現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，自動門已經是隨處可見。自動門不但能給我們帶來人員進出方便、節(jié)約空調能源、防風、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。
自動旋轉門是樓宇設備中的光機電一體化技術產品，它給人以親切大方的感覺，同時營造出奢華的氣氛，其全新的概念，寬敞的開放門面和高格調的設計，堪稱建筑物的點睛之筆，立足于建筑時代大潮的最前端。大廈在需要持續(xù)不斷的人流出入的同時，又要保持建筑物內良好的空氣循環(huán)及環(huán)境的優(yōu)美，這是建筑師所遇到的一大難題，而旋轉門為大廈提供了理想的解決方案，它可有效地防風、防塵和隔音，從而改善了大廈入口附近的環(huán)境。旋轉門的最大優(yōu)點在于它"永遠開門，又永遠關門"，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著。自動旋轉門由于其永遠開啟的同時又永遠關閉的特點，使其動態(tài)密封效果較好。因此，自動旋轉門在功能方面具有獨特的發(fā)展。
1) 旋轉門的定義
旋轉門：單扇或多扇沿豎軸轉動的門叫旋轉門。
自動旋轉門：利用各種控制器、信號控制，實現單扇或多扇沿豎軸自動轉動和自動停止的門叫自動旋轉門。
自動門中的頂級產品，旋轉門給人以親切大方的感覺，同時營造出奢華的氣氛，其寬敞的開放門面和高格調設計，堪稱建筑物的點睛之筆。其全新的概念，無可動搖地立足于建筑時代大潮的最前端。但其高造價也不是一般人能接受的。
2）自動旋轉門的結構
傳統的三翼和四翼旋轉門就是這種結構，即中心門軸通過軸承機構垂直安裝于地面，三個或四個門翼呈發(fā)散式固定在中心門軸上，各門扇之間的角度相等，人在內扇之間推動（按逆時針）門扇，就成為一個手動旋轉門。中心門軸的上方安裝電動機及其他電氣控制部件，再配以感應裝置和安全裝置，就成為自動旋轉門。這種結構是穩(wěn)定性，使用的可靠性很高，使用壽命長?？紤]到旋轉門在停止時一定要密封，所以三翼旋轉門的每個分隔可以容納更多的人，可是門的凈開口的寬度較小。而四翼旋轉門的每個分隔可以容納較少的人，可是門的凈開口寬度卻較大。
但是，這種旋轉門門翼與中心軸的固定方式決定了門扇寬度不能太大，所以這種旋轉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計成了中間展示室，相對減小了門扇寬度，增加了電機對門中心的旋轉作用力矩，使這種旋轉門的最大直徑擴大到6M，中間展示室又有很好的裝飾效果。作為通道門的自動旋轉門還要考慮緊急狀態(tài)時人員的快速疏散，于是旋轉門的門翼要能夠在停電時手動推開，所以帶緊急打開功能的自動旋轉門采用特制的類似合頁的門體接五金件?？墒钱旓L壓很大時，這種門扇結構容易被風吹開。五金件的強度也成為這種自動旋轉門的主要質量問題之一。國際自動旋轉門生產廠又設計了專用的電磁鎖，在斷電時才使門扇可以被推動。
3）自動旋轉門的性能
大廈在需要持續(xù)不斷的人流出入的同時，又要保持建筑物內良好的空氣循環(huán)及環(huán)境的優(yōu)美，這是建筑師所遇到的一大難題，而旋轉門為大廈提供了理想的解決方案，它可有效地防風、防塵和隔音，從而改善了大廈入口附近的環(huán)境。旋轉門的最大優(yōu)點在于它"永遠開門，又永遠關門"，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著。自動旋轉門由于其永遠開啟的同時又永遠關閉的特點，使其動態(tài)密封效果較好。因此，自動旋轉門在保安功能方面具有獨特的發(fā)展，但在人員流量方面自動旋轉門卻沒有優(yōu)勢，因為門的轉速是固定的，每個門翼之間可容納的人員也是有限的。每種自動旋轉門都有標定的人員流量數值。
自動旋轉門由于其永遠開啟的同時又永遠關閉的特點，使其動態(tài)密封效果在經常使用的條件下相對于其它兩種自動門要好。由于自動旋轉門的人流量有限，在大型公共場合還是選擇其它兩種自動門，畢竟自動旋轉門的本成較高。通常在自動旋轉門兩側另設自動或手動平開門，一方面增加通行能力，另一方面當自動旋轉門出現故障時，不影響人的通過。但是在靜態(tài)密封效果方面，自動旋轉門遠不如其它自動門，因為其門體運動方式決定著只能使用毛條密封。
4) 旋轉門在我國的市場前景
隨著我國國民經濟持續(xù)穩(wěn)定地增長，2008年北京申奧成功和WTO的加入。從本世紀開始，我國進入了全面建設小康社會的新階段，創(chuàng)造美好生活環(huán)境是裝飾業(yè)發(fā)展的巨大推動力?，F代城市建筑物裝飾裝修中，將高科技應用到建筑物的外觀形象上，使城市建筑的入口體現出智能化。對門的選擇由單一的功用型向個性化、品位化發(fā)展，旋轉門以其全新的概念，寬敞開放的門面和高格調的設計，自然成為當代的建筑裝飾的主流，無可質疑的必選設施?？胺Q建筑物的點睛之筆。
自動旋轉門控制系統主要由旋轉門、接近傳感器、可編程序控制器和變頻器組成。
1）旋轉門及接近傳感器
該旋轉門由4扇玻璃門相互垂直地鑲嵌在同一個軸柱上構成，電機通過減速機構帶動旋轉門的軸柱，從而產生門的旋轉運動。
為了實現系統的全部自動化和智能化，系統在旋轉門圓形框架的上端，安裝了4個接近傳感器，其中3個面向進門的行人，一個面向出門的行人；在門框外側的邊沿上分別安裝了2套防夾傳感器；在圓弧門框外側的表面上，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
該系統利用三菱公司的FXOS-14MR-001系列PLC，作為該系統的控制指揮中心。該PLC把來自旋轉門現場的檢測信號、變頻器的狀態(tài)信號以及樓宇自動監(jiān)控系統的指令，經過收集、處理后，完成對變頻器的頻率控制和對樓宇自動監(jiān)控系統的信息反饋。
3）變頻器
? 由于旋轉門處于公共場所，行人或物品阻礙旋轉門正常旋轉的現象時常發(fā)生，因此導致電動機的負載變化大、過電流現象發(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的電流限制功能，當負載波動相當大時，變頻器不跳閘，能自動減速運行；當負載恢復正常時，變頻器能自動升速到設定值。使用該變頻器，電動機低速驅動能力強，起動轉矩能達到額定值的150％。該變頻器還具有電壓自整定等一系列先進功能。
? 4）旋轉門運行狀態(tài)診斷程序
?? 樓宇自動監(jiān)控系統除了使用攝像機獲取旋轉門的外部工作狀態(tài)信息外，還需要使用PLC獲取旋轉門控制系統內部的工作狀態(tài)信息。所以在編輯控制系統內部狀態(tài)診斷程序時，不但要照顧到現場維護人員能利用PLC診斷故障，還照顧到樓宇自動監(jiān)控系統準確、方便地使用PLC提供的診斷信息。
綜上所述，該旋轉門設計新穎、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，接近傳感器的可靠性也是實現旋轉門控制系統自動化和智能化關鍵之一。是集機電于一體化的高新技術產品。同時其較好地滿足了廣大用戶的求，擴大了PLC和通用變額器的應用范圍，提高了旋轉門控制系統的自動化和智能化程度，深受物業(yè)管理行業(yè)科技人員和維護人員的青睬。
PLC控制系統硬件設計需滿足如下幾個功能：
(1)自動轉停功能
來人時自動啟動，并以正常轉速動轉，15s時無人進出，則自動停轉并封門。
(2)殘疾變速功能
旋轉門設有低速，中速，高速三種旋轉速度，分別對應殘疾，middle和high三個按鈕進行切換，以適應殘疾人通過、正常運轉和緊急疏散對轉速的不同要求。30s內始終以2r/min的速度低速運轉，此時按中速（Middle）和高速（High）無效，以確保殘疾人安全通過。30s后來人，門自動以正常速度運轉。
(3)防夾功能
當門扇運轉靠近曲壁立柱時，如果行人試圖從兩者之間(防夾區(qū))進入旋轉門，則門立即自動停轉以防夾傷行人。行人離開防夾區(qū)，門自動恢復運轉。
(4)防撞功能
行人緊靠右側立柱或遇到物體碰撞右側立柱,則旋轉門馬上停轉，以防止撞傷行人或撞壞物體，行人或物體離開右側立柱,自動門恢復運轉。
(5)防碰功能
行人在旋轉門內通行過程中，如遇到門扇碰到行人腳后跟，則門立即停轉，以防止碰傷行人。行人離開門扇，門自動恢復旋轉。
(6)急停功能
當出現緊急意外事故十，按下急停按鈕，門立即停轉，解除急停信號，門又自動恢復運轉。
(7)暫停功能(STOP按鈕)
與急停功能相當，不同的是按STOP鈕后，必須用殘疾，middle和high三個按鈕中的一個進行恢復。
(8)電動機過載保護功能
當電動機過載時，門停轉并且指示燈閃爍報警。過載消除后門自動恢復運轉。
(9)變頻器報警輸出和延時自動復位功能
當變頻器過壓或過流時，關閉輸出，門停轉并報警( 指示燈閃爍)，延時3s自動復位。
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，是設計PLC控制系統的首要前提，這也是設計中最重要的一條原則。這就要求設計人員在設計前就要深入現場進行調查研究，收集控制現場的資料，收集相關先進的國內、國外資料。
2) 保證控制系統的安全可靠
保證PLC控制系統能夠長期安全、可靠、穩(wěn)定運行，是設計控制系統的重要原則。這就要求設計者在系統設計、元器件選擇、軟件編程上要全面考慮，以確保控制系統安全可靠。
3）滿足上面條件的前提下，力求使控制系統簡單經濟適用和維修方
在滿足控制要求的前提下，一方面要注意不斷地擴大工程的效益，另一方面也要注意不斷地降低工程的成本。這就要求設計者不僅應該使控制系統簡單、經濟，而且要使控制系統的使用和維護方便、成本低，不宜盲目追求自動化和高指標。
4）選擇PLC是要考慮生產和工藝改進所需的余量
由于技術的不斷發(fā)展，控制系統的要求也將會不斷提高，設計時要適當考慮到今后控制系統發(fā)展和完善的需要。這就要求在選擇PLC、輸入/輸出模塊、I/O點數和內存容量時，要適當留有余量，以滿足今后生產的發(fā)展和工藝的改進。
PLC有兩種基本的工作狀態(tài)，即運行（RUN）狀態(tài)和停止（STOP）狀態(tài)。RUN狀態(tài)是執(zhí)行應用程序的狀態(tài)。STOP狀態(tài)一般用于程序的編制、修改和下載。為了使PLC的輸出能夠及時相應可能隨時變化的輸入信號，用戶程序不是只執(zhí)行一次，而是反復不斷地重復執(zhí)行，直至PLC停機或切換到STOP狀態(tài)，因此PLC采用的是周期循環(huán)掃描工作方式。
一個掃描周期可分為以下5個階段：內部處理階段、通信服務階段、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）內部處理階段
CPU對PLC內部的硬件作故障檢查，復位監(jiān)控定時等。
2）通信服務階段
通信服務階段是掃描周期的信息處理階段，PLC與外圍設備、編程器、網絡設備等進行通信，CPU處理從通信端口接收到的信息。
當PLC處于STOP狀態(tài)時，只執(zhí)行以上兩個階段的操作。當PLC處于RUN狀態(tài)時，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存儲器中，設置了一片區(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的映像存儲區(qū)，它們統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，先讀取輸入端子的當前值，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。
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束，程序運行結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，允許對數字量I/O指令和不設置數字濾波的模擬量I/O指令進行處理，在掃描周期的各個部分，均可對中斷事件進行響應。
5）輸出刷新（輸出處理）階段
每個掃描周期結束時，CPU先把存在輸出映像寄存器中的數據寫入輸出鎖存器中。再輸出到數字量輸出端子，以更新輸出狀態(tài)。然后PLC進入下一個循環(huán)周期，重新執(zhí)行輸入采樣階段，周而復始。
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，對應的輸入映像寄存器為“1”狀態(tài)，梯形圖中對應的輸入繼電器的常開觸點接通，常閉觸點斷開。外接的輸入觸點電路斷開時，對應的輸入映像寄存器為“0”狀態(tài)，梯形圖中對應的輸入繼電器的常開觸點斷開，常閉觸點接通。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)也不會隨之而變，輸入信號變化了的狀態(tài)只可能在下一個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，指令在存儲器中按步序號順序排列。在沒有跳轉指令時，CPU從第一條指令開始，逐條順序地執(zhí)行用戶程序，直到用戶程序結束為止。在執(zhí)行指令時，從輸入映像寄存器或其他元件映像寄存器中將有關編程軟件的0/1狀態(tài)讀出來，并根據指令的要求執(zhí)行相應的邏輯運算，運算的結果寫入到對應的元件映像寄存器中。因此，各編程元件的映像寄存器的內容會隨著程序的執(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，對應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）對應的映像寄存器為“1”狀態(tài)時，稱該編程元件為ON，元件映像寄存器為“0”狀態(tài)時，稱該編程元件為OFF。信號經輸出模塊隔離和功率放大后，繼電器型輸出模塊中對應的硬件繼電器的線圈通電，其常開觸點閉合，使外部負載通電工作。如果梯形圖中輸出繼電器的線圈“斷電”，對應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的硬件繼電器的線圈斷電，其常開觸點斷開，外部負載斷電，停止工作。
譯文
Revolving door originated in Holland, has been one hundred years of history, at that time, before the special meaning from the automatic revolving door to today, revolving door endured a long history. The type is more, according to the control mode can be divided into automatic revolving door, semi-automatic revolving door and manual revolving door; According to the rotor structure can be divided into two wings revolving door way, 3 wing revolving door and 4 wing revolving door; According to the structure into a metal frame revolving door, national crystal revolving door and wood revolving door.
Foreign automatic revolving door development earlier. The technology is relatively mature. The automatic revolving door transmission technology has energy saving, low noise, smooth transmission, long life and reliable performance advantages; The control system using digital design system as the control center, a more powerful, more advantages, such as simple operation; Testing safety system using advanced infrared and microwave induction technology, used for moving object perception, control the operation of the door, use all sorts of safety testing sensor, realize the clip, impact-proof, prevent touch function. At the same time some manufacturers automatic revolving door also has remote control and liquid crystal display function.
Since the establishment of the new China, especially since the reform and opening up, the revolving door of appeared in our country and the various public and high-grade occasion. We stand tall buildings in the city, in the building, hotel, hotel, bank, shopping malls, office buildings, automatic door is everywhere. Automatic door can not only bring us people in and out of convenience, saving energy, including air conditioning, dustproof, and reduce the noise benefits such as to make our doors add a lot of the noble and elegant breath.
The automatic revolving door is building equipment of light machine electricity integration technology products, it gives a person with kind and easy feeling, and build a costly atmosphere, the brand new concept, spacious open appearance and high style design, can be called the nods eyeball pen of buildings, based on the forefront of building age tide. 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 has distinctive function in the development.
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
