The Design And Implementation Of Fiscal Cash Register Based On Embedded System

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...
