【摘要】：本文针对某型号点钞机设计了一种以AT89S52为核心的点钞控制系统。点钞控制系统采用多种方法鉴别伪币,使点钞机在使用上的灵活性大大提高,同时提高了辨别真伪的能力。整个点钞机控制系统从功能上分为三个子系统,数据采集子系统,数据处理及控制子系统,电机驱动子系统。数据采集系统采集荧光、紫外线、红外线、磁信号及安全线信号、进出钞和宽度等辅助信号,这些信号送给数据处理及控制子系统,电机驱动子系统根据数据处理结果由单片机给出控制信号来驱动控制系统执行机构动作,达到对钞票的计数辨伪目的。本文以某型号点钞机为研究对象,围绕其点钞控制系统设计展开研究,做了如下具体工作： (1)对点钞机的结构组成及原理进行了介绍,并给出了点钞控制系统的总体设计方案。 (2)对点钞控制系统鉴伪方法进行了设计。针对人民币上的多种特有特征,分别采用了紫外、红外、磁性安全线等鉴伪方法进行验钞,实现点钞机精准计数、高效鉴伪的功能。 (3)对点钞控制系统硬件选型,进行了硬件电路的设计。按照功能分为了数据采集子系统、数据处理及控制子系统与电机驱动子系统。对整个控制系统进行了PCB的绘制并制作完成了电路板以及硬件完成了初步调试。 (4)进行了点钞控制的软件开发与调试,针对点钞控制三大子系统分别编写了相应软件。软件设计上采用了模块化的思想以便今后可以方便的扩展和重构。
[Abstract]:In this paper, a banknote counting control system based on AT89S52 is designed for a certain type of banknote counter. The banknote counting control system uses many methods to identify counterfeit coins, which greatly improves the flexibility in the use of the banknote counter, and improves the ability to distinguish the authenticity and falsehood at the same time. The whole control system is divided into three subsystems: data acquisition subsystem, data processing and control subsystem, motor driving subsystem. The data acquisition system collects fluorescent, ultraviolet, infrared, magnetic and safety line signals, incoming and outgoing banknotes, width and other auxiliary signals, which are sent to the data processing and control subsystem, According to the data processing result, the motor driving subsystem gives the control signal to drive the control system to carry out the action of the control system, so as to achieve the purpose of counting and discriminating the banknotes. This paper takes a certain type of banknote counter as the research object, carries out the research around the design of the control system of the banknote counting, and does the following specific work: This paper introduces the structure and principle of the banknote counter, and gives the overall design scheme of the banknote counting control system. 2) the method of spoofing control system is designed. Aiming at the special features of RMB, ultraviolet, infrared, magnetic security line and other methods are used to check the banknote, so as to realize the accurate counting of banknote counter and the function of high efficiency in detecting counterfeiting. 3) the hardware selection of the cash counting control system is carried out and the hardware circuit is designed. According to the function, it is divided into data acquisition subsystem, data processing and control subsystem and motor driving subsystem. The whole control system is plotted by PCB and the circuit board and hardware are finished. 4) the software development and debugging of banknote counting control are carried out, and the corresponding software is written for the three subsystems of banknote counting control. In software design, the idea of modularization is adopted so that it can be easily extended and refactored in the future.
