Tax control system based on wireless network tax controller

Abstract

A tax control system based on wireless network tax controller, is composed of a plurality of commercial cashing machines with wireless network card, a network tax controller with wireless switch-in point function and a tax control server, wherein, the network tax controller acquires and processes the sales data of commercial cashing machines to form tax control data, and uploads the tax control data to the tax control server through the local area network. The commercial cashing machines are connected to the network tax controller through the wireless network and / or the wired network, and switches in the local area network. The network tax controller is in wireless connection with a plurality of commercial cashing machines, and is provided with a module for performing supervising and transaction to the composed cluster. Due to the one-to-many regulatory control mechanism between network tax controller and commercial cashing machines; the cost is reduce greatly; the network transmission substitutes the original serial transmission to greatly enhance the data-transmission rate; simultaneously the invention achieves the applications of a relatively high handling ability of the network tax controller.

Description

technical field [0001] The invention relates to a tax control system, in particular to a tax control system based on a wireless network tax controller. Background technique [0002] The POS sales system with a local area network is a commodity sales application system widely used by large and medium-sized retail stores and fast food chains. [0003] A few days ago, the relevant standards for tax-controlled cash registers are also being introduced one after another. The basic working mode of commercial cash register + tax controller + tax control card + tax-controlled cash register management system has been established. The basic principles have favorably promoted the orderly conduct of commercial taxation work. [0004] At present, the network tax controller with increased LAN communication interface and expanded memory has also been finished. The network tax controller is connected with the commercial cash register through the serial port, and realizes one-to-one supervi...

Problems solved by technology

But this connection method has at least the following disadvantages: for large supermarkets, it is necessary to additionally equip more network tax controllers, which is not a small cost; on the other hand, the data transmission rate of the serial port is lower than that of the network. There is a large gap, so this change in the transmission method not only reduces the cost, but also makes more effective use of the system resources of the network tax controller
