【摘要】：隨著近些年來軌道交通基礎設施建設規(guī)模的不斷擴大,其配套設施的建設費用也不斷增長。其中一類比較重要的配套設施就是地鐵自動售檢票系統(tǒng)。國內(nèi)的地鐵自動售檢票系統(tǒng)中的紙幣接收模塊無一例外的使用了進口的紙幣接收模塊。進口紙幣模塊的設計需求完全是為了滿足國外的壞境以及用戶需求。國外的紙幣一般較新,褶皺少且磨損少。進口紙幣模塊在設計時比較少的考慮紙幣在傳輸通道內(nèi)折疊、卡死或打滑等問題,所以在設計時會使用皮筋傳輸這一類很不穩(wěn)定的傳送設計。因為國外儲值卡和硬幣使用量較大,紙幣用量較小,進口紙幣模塊設計時很少考慮紙幣循環(huán)找零問題。在中國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。進口紙幣模塊工作在中國的環(huán)境下難免水土不服。本文根據(jù)地鐵自動售票機的紙幣接收模塊總體的應用環(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構。這種傳送結構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械結構,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。這種功能的實現(xiàn)解決了小面額紙幣在設備內(nèi)積壓的問題。本文完成了新型紙幣壓箱機構的研究,完成了紙幣模塊所使用的電機、電磁閥的選型。本文通過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)、相關的電子電路以及紙幣接收模塊的紙幣識別器。本文在研究過程中重點對機械傳動機構以及相關的變頻電機功率控制電子電路、紙幣儲幣箱及紙幣壓箱機械結構電路中的串口芯片相關的附屬擴充接口進行定型。論文在設計過程中依據(jù)需要研究了兩種結構的紙幣換向閥,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程,得到了紙幣與不同結構紙幣換向閥撞擊過程中的應力圖,并以此選取了最佳的紙幣換向閥結構,保證了紙幣在紙幣模塊的工作過程中不受損傷。本人通過制作紙幣傳輸通道實物來進行物理實驗,驗證了模擬仿真結果的正確。此論文的目的是研究并同時研制一款獨創(chuàng)的具有循環(huán)找零功能的新型紙幣接收模塊,并且獨立研發(fā)產(chǎn)品的機械結構,確定機械參數(shù)。其獨創(chuàng)的紙幣循環(huán)找零結構的研究和設計能夠解決目前紙幣模塊普遍缺少紙幣循環(huán)找零功能的問題,為以后研發(fā)符合中國國情的具有紙幣循環(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.
