摘要 旅客登機橋是應(yīng)用于各大航空機場的輔助設(shè)備，是機場用以連接候機廳與飛機之間的可移動升降的通道。每個機場都有多個登機橋位，就是連接候機樓和飛機艙門的橋。一端連接候機樓的某個登機口，一端扣在飛機艙門上，旅客由對應(yīng)登機口進入飛機。與登機橋相同作用的還有客梯車，客梯車在乘客上下飛機時將梯口對準(zhǔn)飛機艙門。旅客通過登機橋上下飛機而不是通過飛機場跑道，這樣很大程度上給予乘客舒適與安全。而且，隨著全球經(jīng)濟的飛速發(fā)展，登機橋的需求也會越來越大。
在登機橋的設(shè)計過程中，如何設(shè)計出適合各種運行情況登機橋這一問題顯得尤為重要，當(dāng)然登機橋的運行離不開一個可靠的控制系統(tǒng)，華德寶機械有限公司一直致力于研發(fā)制造旅客登機橋，其中，對于公司的控制系統(tǒng)，它采用的是RockWell公司生產(chǎn)的PLC，并通過HMI運用觸摸屏實現(xiàn)對登機橋的工作操作,包括旅客登機橋的升降行走以及當(dāng)?shù)菣C橋的某一模塊出現(xiàn)故障時能夠及時得到報警通知，有效的防止事故的發(fā)生。當(dāng)然，登機橋囊括了有關(guān)機械，材料，力學(xué)，電氣的方方面面，究于本專業(yè)的要求，我所研究的方向就是電氣方面PLC對于登機橋的控制。
首先，學(xué)習(xí)PLC的編程軟件RSLogix5000，并且深入了解該軟件對于程序?qū)嵭械木唧w功能。
其次，根據(jù)國家標(biāo)準(zhǔn)以及對旅客登機橋在升降系統(tǒng)的要求進行編寫PLC程序的工作，并且配合其他PLC的具體控制要求對登機橋的升降系統(tǒng)進行實時操作運行，觀察所編寫的程序能否實現(xiàn)該功能。
最后，對旅客登機橋的升降系統(tǒng)做一個整理歸納。

         Research on PLC control system for passenger boarding bridges
Abstract Passenger boarding bridge is an auxiliary equipment used in major aviation airport, and it is the airport with mobile lifting to the connection between the terminal and the plane channel. Each airport has a plurality of boarding bridge, which is the connection terminal and the aircraft door bridge. One end is of a connecting terminal gate mouth, one end is buckled in the doors of aircraft, passenger aircraft by entering the corresponding gate. The same effect with the boarding bridge and passenger car, passenger car in the passenger on a plane when the aircraft door ladder hole alignment. Passenger boarding bridge by plane instead of the runway of the airport, so largely to passenger comfort and safety. But, with the rapid development of global economy, the boarding bridge will be growing its demand.
In the process of designing the boarding bridge, how to design a suitable one for all kinds of operations is the most important issuse, of course, the boarding bridge operation cannot do without a reliable control system, Hua Debao Machinery Co., Ltd. has been dedicated to R & D and manufacturing passenger boarding bridge, which, for the control system of the company, it uses RockWell PLC company production, and using the touch screen to achieve the boarding bridge work operation through the HMI,including lifting walking passenger boarding bridges and when a module of the boarding bridge failure can be alarm notification timely, effectively prevent accidents. Of course, the boarding bridge include related machinery, materials, mechanical, electrical aspects, in the professional requirements, my research direction is electrical PLC for control of the boarding bridge..
First of all, learning PLC programming software RSLogix5000, and in-depth understanding of the functions of the software for program implementation.
Secondly, according to the national standard and the PLC procedures for the preparation of passenger boarding bridges on the lifting system requirements, and with the specific control of other PLC requirements for boarding bridge lifting system for real-time operation, observing the program whether can achieve the function
Finally, making a summarize of the lifting system for passenger boarding bridges.
