Research And Prototype Design Of The Architecture Of The Wireless Network Tax Controller Based On SOPC

Revenue, as a legal system which can conduct the tax distribution relationship between the nation and taxpayers, is of great significance in our society. The revenue loss is a serious problem affecting the development of the country. Therefore, the strengthening of the construction of tax information and reducing of the revenue loss effectively are especially important. Improved tax system is an important safeguard to maintain national interests.GB18240.7 prototype systems project is mainly for large retail shopping malls, supermarkets and large chain fast-food industries which use POS systems, business systems management and financial management by using tax control system for cash registers. The idea of the system is to assess tax during the sales process. The topic of this article is based on the project, and it gives some improvements of the design.In the original system, every cash register equips with a network tax controller, and it is responsible for analysis of sales data. This paper brings up a new one-to-many SOPC-based network architecture. In this system, a network tax controller controls many cash registers, which through a wireless network for data transmission. In this star-shaped one-to-many architecture, the system can not only effectively lower the cost, but also substantially increase the efficiency of the network tax controller, and can avoid the restrictions on connection of wiring harness. At the same time, the network tax controller based on SOPC technology can increase flexibility of system design and life cycle, and can avoid the risk of design out-of-date.This topic studies and designs a one-to-many wireless network tax controller architecture based on ZigBee Wireless Personal Area Network. Compared to the 802.11 wireless LAN, Bluetooth, IrDA and other wireless transmission solutions ,ZigBee can meet the requirements of data transmission between the network tax controller and the POS very well because of its low power consumption, simple protocol, low cost, short time delay, safe and reliable transmission and etc. Meanwhile it can also reduce the costs. This paper designs a set of solution of wireless network tax controller based on SOPC, so as to achieve the aim at one network tax controller control many cash registers.The subject can play an active role in perfecting the commercial enterprises'tax system, and has great significance in construction of the national tax informationization.
