【摘要】：紙幣識別器被廣泛應(yīng)用于銀行、零售、交通等需要自助繳納紙幣的場所，目前各金融行業(yè)的紙幣識別器產(chǎn)品多為國外產(chǎn)品，為打破國外在紙幣識別器行業(yè)上的壟斷局面，滿足國內(nèi)金融行業(yè)對紙幣識別器高性價比的要求，有必要針對人民幣，研制一種高可靠性且集紙幣真?zhèn)舞b別、防釣幣及紙幣壓箱等功能于一體的紙幣自動識別系統(tǒng)。 本文首先對國內(nèi)紙幣識別器市場進(jìn)行了調(diào)研，通過對國外主要紙幣識別器產(chǎn)品的主要功能及性能進(jìn)行了分析研究，明確了針對國內(nèi)人民幣的紙幣識別器產(chǎn)品的功能及參數(shù)，并對紙幣識別器的關(guān)鍵技術(shù)進(jìn)行了分析。 對紙幣識別器的關(guān)鍵結(jié)構(gòu)進(jìn)行了設(shè)計，主要包括紙幣傳輸機(jī)構(gòu)、紙幣糾偏結(jié)構(gòu)及壓箱機(jī)構(gòu)，重點討論了運用ADMAS對壓箱機(jī)構(gòu)進(jìn)行了運動學(xué)及動力學(xué)分析，結(jié)果表明：擺桿式壓箱機(jī)構(gòu)驅(qū)動力矩及壓軸力較凸輪式壓箱機(jī)構(gòu)大，但是考慮到凸輪式壓箱機(jī)構(gòu)的可靠性不如擺桿式壓箱機(jī)構(gòu)好，且位置選擇受限較大，最后選擇了擺桿式壓箱機(jī)構(gòu)。 對紙幣識別器的關(guān)鍵零部件進(jìn)行了仿真分析，針對壓箱機(jī)構(gòu)驅(qū)動輪軸承受巨大的壓軸力，運用ABAQUS對壓箱機(jī)構(gòu)的固定支架進(jìn)行了強度校核，仿真表明：固定支架的強度滿足要求；運用ABAQUS對安全錢箱進(jìn)行了跌落仿真，仿真表明：安全錢箱底面及尖角首先著地時，其應(yīng)力、應(yīng)變及動能存在巨大的突變，但是應(yīng)力仍小于其材料的屈服應(yīng)力，即安全錢箱滿足跌落強度要求。 對紙幣識別器系統(tǒng)進(jìn)行了集成測試，測試的項目主要包括紙幣識別器通道的順暢性測試、紙幣位置傳輸偏差測試及紙幣識別器連續(xù)性工作穩(wěn)定性測試（包括運行穩(wěn)定性測試、掃描一致性、卡幣率及壓幣穩(wěn)定性測試），測試表明：各項測試均滿足測試要求，具有較高的穩(wěn)定性。 本文是對金融領(lǐng)域識幣產(chǎn)品的開發(fā)，，主要進(jìn)行了紙幣識別系統(tǒng)結(jié)構(gòu)的設(shè)計及分析，討論了紙幣傳輸、紙幣糾偏及壓箱等問題，得出的一些結(jié)論、數(shù)據(jù)，為紙幣識別設(shè)備及其它相關(guān)設(shè)備的功能實現(xiàn)提供了一定的參考，研制的紙幣識別器產(chǎn)品具有一定的應(yīng)用價值。
[Abstract]:Paper currency recognizer is widely used in banks, retail, transportation and other places to pay paper money. At present, most of the banknote recognizers are foreign products. In order to break the monopoly situation in the paper currency recognition industry and meet the demand of high price ratio of banknote recognizers in the domestic financial industry, it is necessary to aim at the people. Currency, the development of a high reliability and authenticity of paper currency identification, anti fishing currency and banknote pressure box functions in one automatic banknote recognition system.
In this paper, the domestic paper currency recognizer market is investigated and the main function and performance of the foreign main paper currency recognizer products are analyzed and studied. The functions and parameters of the banknote recognizer products in China are clarified, and the key technology of the paper currency recognizer is analyzed.
The key structure of the paper currency recognizer is designed, mainly including the paper currency transmission mechanism, the paper currency rectification structure and the pressure box mechanism. The kinematic and dynamic analysis of the press box mechanism by using ADMAS is emphatically discussed. The results show that the driving torque and the axial force of the pendulum rod type pressure box mechanism are larger than that of the convex wheel type pressure box mechanism, but the convex hull mechanism is considered to be convex. The reliability of the wheel press box mechanism is not as good as that of the swing bar press box mechanism, and the location selection is limited. Finally, the swing bar type pressure box mechanism is selected.
The key parts of the paper currency recognizer are simulated and analyzed. The strength check is carried out by ABAQUS for the fixed support of the pressure box mechanism. The simulation shows that the strength of the fixed bracket meets the requirements. The simulation shows that the safety money box is falling down with ABAQUS, and the simulation shows that the safety of the safety money box is safe. The stress, strain and kinetic energy of the bottom of the box and the tip of the box have a huge sudden change, but the stress is still less than the yield stress of the material, that is, the safety box meets the drop strength requirement.
The integrated test of the paper currency recognition system is carried out. The test items mainly include the smoothness test of the banknote identifier channel, the deviation test of the paper currency position transmission and the stability test of the continuous work of the banknote recognizer (including the running stability test, the scanning consistency, the card currency rate and the stability test of the currency). It meets the test requirements and has high stability.
This article is the development of money recognition products in the financial field, mainly the design and analysis of the structure of the paper currency recognition system. The paper discusses some problems, such as paper currency transmission, paper currency correction and pressure box, and some conclusions and data, which provide some reference for the function realization of paper currency recognition equipment and other related equipment. It has a certain value of application.
