【摘要】 税收制度是每个国家赖以生存的保障,它的重要性不言而喻。税控收款机作为税收电子化的“咽喉要道”,是最重要的税收工具,它的推广和应用关系到国计民生,对于帮助国家税收征收和稽查具有决定性的意义。税控收款机是在普通收款机的基础上,增加税控功能,采用智能卡、数字加密和网络技术,将纳税人申报数据与税控收款机记录的数据进行比对,实现对纳税人经营情况的有效监控,也为实施纳税评估和税务稽查提供重要依据,使税务机关的监控触角延伸到纳税人的经营数据形成的过程中,使税务稽查有一个依据。税控收款机不仅应保证经营数据的正确生成、可靠存储和安全传递,而且应当具有适合各个层面用户的良好的人机互动界面。笔者根据国家近期公布的推广税控收款机的计划,在深入分析国内税控收款机市场的现状和不足以及它的发展前景后,提出了一种基于Arm9+Linux的税控收款机方案,其性价比高且具有广泛的市场应用价值。本论文在总体设计上采用了层次化设计和模块化设计的方法。本论文设计的税控收款机自底而上分为四层:分别是:硬件电路层、底层驱动层和操作系统层以及上层应用层。各层均按功能模块进行划分,各模块完成一定的功能。这种分层设计与模块化设计的方法使各层和各功能模块之间相对独立,有利于系统维护与改进,并使其具有良好的可扩展性。本文首先概要介绍了税控收款机以及论文研究意义等;然后对整个方案的整体设计进行了分析;接着对最底硬件电路层设计进行了详细的分析;并对Linux操作系统的移植和驱动层,应用层的移植开发思路进行了具体阐述;最后对税控收款机的安全性设计进行了分析。更多还原

【Abstract】 The collection of revenue is very important for every country.The tax-controlled machine is the key for electronicization of revenue.As the important tools of tax-collection,its application and popularization is crucial for the collection and check of revenue.This fiscal cash not only has the tax-collected function but has the tax-controlled function. It uses the IC card and encrypted data and network technique to monitor and control the taxpayer through the comparison the declarable data by taxpayer to the intercepted data by fiscal cash. It also affords important clues to the evaluation and check of tax payment. The tax-controlled machine is an electronic cash collector plus the tax-controlled function. It should guarantee the correct data incepted and stored and safe transfer and the same time it should offer the user a human mutual graphic interface.According to the plan of tax-controlled machine extendance of chinese revenue,I have researched the shortcomings and forground in the market.I designed a commercioganic tax-controlled machine project who base on the ARM9 and Embeded Linux.The paper design the fiscal cash as the arrange and modularization regulation.The tax machine has four levels in the software structure:hardware circuit、device driver、Linux OS、application level.This design method has good independency and easy-porting capability and good extendance performance.The paper first introduced the fiscal cash and the research intention of the author; Then it detailed analyse the total design of the project; and then it tell us how to design the bottom Hardware circuit and how to program and port the Linux OS & device driver & application & GUI.At last the paper analyze the security design of fiscal cash.更多还原
