【摘要】 现代信息技术的高速发展给各行各业带来了变革。“金税工程”就是国家税务总局适应发展形势建设的税收信息管理系统工程，目的是要依托现代网络、通信技术，加强对增值税专用发票的管理和监控；要推广使用“税控收款机”，逐步取代传统电子收款机等商业销售终端；采用更加先进的电子信息技术，用“电子发票”和带防伪标识的机器打印发票取代传统手工开具的发票，杜绝发票造假，进而逐步实现税务电子化。随着Internet技术的发展，越来越多的企业(集团)利用网络平台交流信息和共享资源，进行各种电子商务。对于商业企业，商业管理自动化、信息化成为发展的必然趋势。谁能够及时把握进、销、存等各种商业信息，实现资源和信息的充分共享，谁就能够抢占市场先机，在激烈的商业竞争中处于不败之地。因此，众多商业企业(集团)迫切需要改进他们的传统商业销售终端(POS，Point of Sales)及其管理系统。 本文的项目正是在这样的背景下产生，采用先进的嵌入式技术、通信网络技术，设计了一种新型的商业销售终端，以及基于Internet的终端管理系统、增值业务系统。本文研制的新型商业销售终端，既是一个符合国家标准的“税控收款机”，满足“金税工程”的税控需求；又有许多扩展功能，可以胜任现代各种复杂的“POS系统”中收款机和智能型终端的角色。设计的网络运行与管理系统，是一个先进的、高效的、低成本的企业信息化平台方案，完全满足现代商业自动化的需求。 本文主要完成了如下几方面的工作： 1．新型商业终端设计：创新的采用32位MCU，结合嵌入式实时操作系统(RTOS)的设计方案，兼具功能和成本的双重优势。 2．终端管理系统设计：成功实现了嵌入式系统的网络接入，建立起基于Internet的网络管理系统，满足税务部门税务征收和稽查的功能，率先实现网络报税，实现真正的“税收电子化”。并且采用自行设计应用层，并通过加密算法和增加双重身分认证等手段，充分保证数据的安全性。 3．综合业务管理系统设计：综合采用两层和多层结构模型，融合C／S与B／S两种模式的优点，充分满足商业企业(集团)、行业应用的需求。 4．增值业务平台设计：为商业企业实现充分资源与信息共享，达到互惠互利而设计的信息化平台，甚至可以实现不同企业、不同行业的“虚拟连锁”，这是一个大胆的创新设计。更多还原

【Abstract】 The high-speed development of modern information technology brings profound change to every industry. "Golden Tax Project" is the generalized name of Tax Information Management System Project, which is erected by China State administration of Taxation. The destined intention of this project is to erect a computer network, through which we not only can share information, but also can strengthen the management and monitor of added-valued invoices all over the country. Moreover, it initiates the working principle of "control taxation by invoice" . The first step we should take is settling the anti-counterfeiting of invoice itself. Traditionally, its anti-counterfeiting depends on particular paper and special print technology, which can be mocked easily with the print technology development. In addition, the cost of traditional anti-counterfeiting is very high. We need a reliable system with high efficient and low cost. So comes the Gold Tax Project. Firstly, Tax Controlled Cash Register is introduced into this project and they will replace the electronic registers that are used now. This new register adopts advanced electronic technology, which can produce Electronic Invoice. At the same time, invoice with particular anti-counterfeiting mark is available. So, the manuscript invoice will be replaced.On the other hand, commerce automation is the trend of modern business. The strengths of chained management are unfolded to us. Whoever grasps and makes best of the information of buying, sold and stock in time, he will be as the industry leader. Only so can he keeps his company competent and never lose to its rivals. So, more and more companies/corporations want to reform their traditional POS (Point of Sales) terminals and its related management system.The proposed project in this paper was put forward under foregoing circumstances. Advanced embedded technology and communication network technology are adopted into this new type of business POS terminal. Its management system and added-value business system is based on Internet. This new POS is not only a standardized Tax Controlled Cash Register, but also a good tool with many other extension functions. It can work both as a cash register and an intelligent terminal in "POS system" .Its Internet operation and management mode can fully meet the demand of modern business company. It is a good Company information Platform with features of advanced technology, high efficiency and low cost.The following tasks are covered in this paper:1. Design of new POS: MCU of 32 bits, combined with embedded real-time operation system (RTOS) is the main design plan. It has virtue of strong functions and low cost.2. Design of terminal management system: Internet access of embedded system has been achieved. Network management based on Internet is realized. All the taxation steps such as tax collection, tax check and invoice preparation can completely meet the needs of administration of Taxation. The system’ s data security is guaranteed by adopting self-designed appliance layer, encryption operation, double authentication and so on.3. Design of synthesized business management system: multi and double layers model get used neatly. It features the merits of C/S and B/S. So, it can fully satisfy the flexible management of commerce company/corporation.4. Design of added-value business platform: this platform can realize"virtual connection" between different company and different industries if necessary, which is an absolutely creative design.更多还原
