多槽式鈔票整理機之出入鈔控制與磁性檢測的分析研究與實現

多槽式鈔票整理機其快速的處理能力，需要高度的技術整合能力。然而，整理機的技術多掌握在歐美日少數專業廠商手上。隨著市場需求的快速變化，傳統的驗鈔機已無法滿足客戶實際需要，提升鑑偽速度及商品化是主要的努力方向。研究主要以PIC18F4431單晶片為控制核心，改善一般鈔票整理機的出入鈔控制、磁性檢測，提升辨識速度。硬體以DC (24V) 馬達驅動結合離合器、旋轉電磁閥、剎車、編碼器、IR Sensor等元件控制鈔票出入鈔的動作。真偽辨識部分選用BS05C1HFAA磁性感應器，利用鈔票上微量磁性油膜進行辨識。同時，利用霍爾感應器組成的厚度偵測平台,實現鈔票厚度的辨識。控制軟體使用C語言撰寫，並於Microchip的開發環境MPLAB下發展。硬體電路架構參考業界常使用的控制電路，並加以創新改良。使用的零組件也以業界常使用且易取得為原則，目的使本文所完成的電控系統，在軟硬體方面，均能立即轉換成業界所能量產及使用的產品。實驗結果，整體電控系統以500張/分的速度進行磁性檢測，辨識率為95%。

Fast processing Multi-slot Machine Banknote Sorters for require a high technical integration. However, the main mature technologies are mastered by several specialized companies in Europe, Japan and U.S. With the rapid changes in market demand, the conventional currency detector cannot meet the actual needs of customers. Therefore the paper is mainly focused on enhance the recognition rate and speed to meet the commercial development. In this study, the single-chip microprocessor (PIC18F4431) functioned as a control center improves the transfer control and the authenticity of magnetic detection of the Multi-slot Machine Banknote Sorter to enhance the recognition rate. The motor to control the action of the banknote is driven by DC (24V) with clutch, Bistable Rotary Solenoid, brake, encoder, and IR Sensor components. Authenticity of the banknote is identified by tracing the micro magnetism with the magnetic sensors BS05C1HFAA. To improve the thickness detection, we use two precise Hall transducers that can measure the thickness under 0.03 mm. The software programs are developed in C language based on the MPLAB development tool by Microchip Technology Incorporation. Hardware circuit architectures take the common industry circuit as the reference for improvement and innovation. The using spare part as far as possible is often used by the industry and easy to obtain. The purpose of the study is to complete the electronic control system in terms of hardware and software that can be immediately converted into the industry's products and mass-production. Use Hall sensors detect the thickness of banknotes. From the experimental results, the control system can execute the magnetic detection by the speed of 500 pieces per minute, and recognition rate is 95%.
