Development And Management Research Of Embedded System Based On Internet

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.
