【摘要】 随着国家金税工程的不断深入，国税总局在全国全面推广税控收款机的使用。目前，普通的税控收款机有着成本过高、管理不方便等缺点，而基于嵌入式系统的税控收款机则具有成本低、可靠性高，而且由于采用嵌入式操作系统，其具有易管理、安全性高等优势。因此，在技术和市场两方面的驱动下，本文提出了基于嵌入式系统的税控收款机的方案，将嵌入式技术与税控收款机技术有机结合起来，开发出一种新型的税控收款机产品，这对促进国家金税工程的实施具有非常重大的意义。 基于嵌入式系统的税控收款机是一个复杂的嵌入式应用系统，涉及到嵌入式系统、智能卡、电路设计、税控应用等多种软硬件技术。为了降低研发成本和缩短研发周期，该税控收款机部分模块采用了成熟的技术和产品，如智能卡技术和税控专用外设，本文的重点放在嵌入式系统、电路设计和税控应用程序开发等技术问题上。 根据《税控收款机国家标准》，本课题对基于嵌入式系统的税控收款机进行了设计和研制。本文阐述了以君正微处理器Jz4720为核心的硬件设计，包括各个主要的功能模块；然后在此基础上，详细分析了开发环境的建立，硬件模块驱动程序、图形用户界面的设计和税控应用程序的开发等。 实践证明，该税控收款机的设计是符合国家标准并能够满足用户需求，是成功的。目前课题已接近尾声，并进入最后的完善阶段，这为下一步的研发工作打下了良好的基础。相信随着税控市场的全面推广，该嵌入式税控收款机将会有十分广阔的市场前景。更多还原

【Abstract】 With the development of National Golden Tax Project, the fiscal cash register is applied into this field all over the country by the State Administration of Taxation. But at the present time, most of the fiscal cash registers have the disadvantages of high cost, managing inconvenience. In contrast, the fiscal cash registers based on embedded system have advantages of low cost, managing convenience, high dependability and security and etc. So in the impulse of technology and market, we put forward a scheme of fiscal cash register. In this scheme, we combine fiscal cash register technology and embedded system technology organically and develop a new type, which also is very meaningful to the implementation of Golden Tax Project.The fiscal cash register based on embedded system is a complex embedded application system, which relates to many kind of software and hardware technology, such as embedded system technology, intelligentized card technology, circuit design and fiscal application technology and etc. In order to reduce the cost and shorten the cycle of development, we adopt some mature products and technology for some parts of the fiscal cash register, such as intelligentized card technology and some special fiscal facilities. This thesis discusses the technology problems in embedded system, circuit design and development of fiscal application program emphatically.According to the 《fiscal cash register national standard》, the thesis designs and develops a fiscal cash register embedded on system. And the thesis expatiates on the hardware design which include most part of function part; after this, it analyzes the construction of cross compile environment, design of drivers and GUI and development of fiscal application.Practice proved that the design of this fiscal cash register accord with the national standard and can meet with the users’ need, so it is successful. At present, this project更多还原
