【摘要】：隨著近些年來(lái)軌道交通基礎(chǔ)設(shè)施建設(shè)規(guī)模的不斷擴(kuò)大,其配套設(shè)施的建設(shè)費(fèi)用也不斷增長(zhǎng)。其中一類(lèi)比較重要的配套設(shè)施就是地鐵自動(dòng)售檢票系統(tǒng)。國(guó)內(nèi)的地鐵自動(dòng)售檢票系統(tǒng)中的紙幣接收模塊無(wú)一例外的使用了進(jìn)口的紙幣接收模塊。進(jìn)口紙幣模塊的設(shè)計(jì)需求完全是為了滿(mǎn)足國(guó)外的壞境以及用戶(hù)需求。國(guó)外的紙幣一般較新,褶皺少且磨損少。進(jìn)口紙幣模塊在設(shè)計(jì)時(shí)比較少的考慮紙幣在傳輸通道內(nèi)折疊、卡死或打滑等問(wèn)題,所以在設(shè)計(jì)時(shí)會(huì)使用皮筋傳輸這一類(lèi)很不穩(wěn)定的傳送設(shè)計(jì)。因?yàn)閲?guó)外儲(chǔ)值卡和硬幣使用量較大,紙幣用量較小,進(jìn)口紙幣模塊設(shè)計(jì)時(shí)很少考慮紙幣循環(huán)找零問(wèn)題。在中國(guó)小面額的紙幣被大量的使用,且紙幣狀況參差不齊,很多紙幣爛舊了依然在使用。進(jìn)口紙幣模塊工作在中國(guó)的環(huán)境下難免水土不服。本文根據(jù)地鐵自動(dòng)售票機(jī)的紙幣接收模塊總體的應(yīng)用環(huán)境以及所需要的功能研究了使用扁平皮帶的紙幣傳送結(jié)構(gòu)。這種傳送結(jié)構(gòu)可以極大的降低紙幣在傳輸通道內(nèi)折疊、卡死或打滑等問(wèn)題出現(xiàn)的概率。本文研究了具有循環(huán)找零功能的新型紙幣接收模塊的機(jī)械結(jié)構(gòu),使得紙幣模塊能夠?qū)崿F(xiàn)紙幣循環(huán)找零這一種全新的功能。這種功能的實(shí)現(xiàn)解決了小面額紙幣在設(shè)備內(nèi)積壓的問(wèn)題。本文完成了新型紙幣壓箱機(jī)構(gòu)的研究,完成了紙幣模塊所使用的電機(jī)、電磁閥的選型。本文通過(guò)分析紙幣接收模塊控制系統(tǒng)的功能需求研究完成了紙幣接收模塊的控制系統(tǒng)、相關(guān)的電子電路以及紙幣接收模塊的紙幣識(shí)別器。本文在研究過(guò)程中重點(diǎn)對(duì)機(jī)械傳動(dòng)機(jī)構(gòu)以及相關(guān)的變頻電機(jī)功率控制電子電路、紙幣儲(chǔ)幣箱及紙幣壓箱機(jī)械結(jié)構(gòu)電路中的串口芯片相關(guān)的附屬擴(kuò)充接口進(jìn)行定型。論文在設(shè)計(jì)過(guò)程中依據(jù)需要研究了兩種結(jié)構(gòu)的紙幣換向閥,使用有限元的方法解析紙幣和兩種紙幣換向閥的撞擊過(guò)程,利用Ansys軟件創(chuàng)建紙幣撞擊換向閥的有限元模型,用Ansys軟件模擬仿真了紙幣與紙幣換向閥的碰撞過(guò)程,得到了紙幣與不同結(jié)構(gòu)紙幣換向閥撞擊過(guò)程中的應(yīng)力圖,并以此選取了最佳的紙幣換向閥結(jié)構(gòu),保證了紙幣在紙幣模塊的工作過(guò)程中不受損傷。本人通過(guò)制作紙幣傳輸通道實(shí)物來(lái)進(jìn)行物理實(shí)驗(yàn),驗(yàn)證了模擬仿真結(jié)果的正確。此論文的目的是研究并同時(shí)研制一款獨(dú)創(chuàng)的具有循環(huán)找零功能的新型紙幣接收模塊,并且獨(dú)立研發(fā)產(chǎn)品的機(jī)械結(jié)構(gòu),確定機(jī)械參數(shù)。其獨(dú)創(chuàng)的紙幣循環(huán)找零結(jié)構(gòu)的研究和設(shè)計(jì)能夠解決目前紙幣模塊普遍缺少紙幣循環(huán)找零功能的問(wèn)題,為以后研發(fā)符合中國(guó)國(guó)情的具有紙幣循環(huán)找零功能的紙幣接收模塊做參考。
[Abstract]:With the expansion of the construction scale of rail transit infrastructure in recent years, the construction cost of its supporting facilities is also increasing. One of the more important supporting facilities is the subway automatic ticketing system. The paper money receiving module in the automatic selling and checking system of domestic subway uses the imported paper money receiving module without exception. The design demand of import paper money module is to satisfy the bad condition and user demand of foreign countries. Foreign notes are generally newer, less wrinkled and less worn. In the design of imported paper money module, the problems of paper currency folding, sticking or slipping in the transmission channel are less considered, so the design will use leather tendons to transmit this kind of very unstable transmission design. Because the use of foreign stored value cards and coins is large and the amount of paper money is small, the circular change of paper currency is seldom considered in the design of import paper money module. Small denominations are widely used in China, and they are uneven, and many are still in use. Imported paper money module work in China's environment is inevitable. In this paper, the paper studies the paper currency transfer structure using flat belt according to the general application environment and the needed function of the paper money receiving module of the automatic ticket vending machine. This transmission structure can greatly reduce the probability of paper currency folding, sticking or slipping in the transmission channel. In this paper, the mechanical structure of a new type of paper money receiving module with cyclic change function is studied, which enables the paper currency module to realize the new function of circular change of paper currency. The realization of this function solves the problem of small denomination paper money backlog in the equipment. This paper has completed the research of the new banknote press box mechanism and completed the selection of the motor and solenoid valve used in the banknote module. By analyzing the functional requirements of the paper currency receiving module control system, the paper completes the paper currency receiving module control system, related electronic circuits and the paper currency recognizer of the paper currency receiving module. In this paper, the mechanical transmission mechanism and the related power control electronic circuit of frequency conversion motor, the auxiliary extended interface related to serial port chip in the mechanical structure circuit of paper currency storage box and paper currency pressure box are finalized. In the course of design, the paper studies two kinds of banknote directional valve according to the need. The finite element method is used to analyze the impact process of banknote and two kinds of banknote directional valve, and the finite element model of banknote impact directional valve is created by using Ansys software. This paper simulates the collision process of banknote and banknote reversing valve with Ansys software, obtains the stress diagram during the impact process of banknotes and banknotes with different structure, and selects the best structure of banknote reversing valve. It ensures that the paper money will not be damaged in the working process of the paper money module. The physical experiment of paper currency transmission channel is carried out, and the simulation results are verified. The purpose of this paper is to study and develop a new kind of paper money receiving module which has the function of circular change and independently develop the mechanical structure of the product and determine the mechanical parameters. The research and design of its original paper currency cycle change structure can solve the problem that the paper currency module generally lacks the paper currency cycle change function, which can be used as a reference for the future research and development of the paper currency receiving module with the paper currency cycle finding function which is in line with the Chinese national conditions.
