Design And Implementation Of XYT-Embedded Terminal Order System

Since founding of New China 60 years ago, the tobacco industry in the party's correct leadership and the strong support of the country has achieved tremendous success and development. Besides the deepening of reform, it becomes an important corporate profits and taxes gradually. Tobacco companies through their own continuous development, social progress, and gradually realize the importance of the development of information technology. However, due to the special nature of the industry and the many historical reasons, tobacco is often a correlation between information systems is not strong, the lack of information exchange and other defects. Today, business and information technology is no longer simply rely on a few office software will be able to achieve the enterprise modernization management era. In a customer-oriented in order to change the theme of today, the tobacco industry urgently needs to upgrade its own level, process optimization, the appropriate use of technology enables its quick response to market changes, customer needs, to more high-quality and efficient for customer service. At the same time as computer science, and the development of networks, embedded system in all aspects of our lives, play an important role. Will be professional and flexible deployment of embedded intelligent terminal to the retailer, not only can provide a richer retailer management functions of goods, more importantly, the tobacco logistics tracking tentacles further extended to the terminal, from terminal to provide accurate and Also detailed information, for the tobacco companies get through from production to sale of the entire process. Thus becoming a very efficient and fast information gathering and distribution system to further help the tobacco companies develop management decisions.In this paper, object-oriented thinking in order to UML for the analysis and design tool for embedded intelligent terminal orders the letter ETS system requirements analysis and design. According to the characteristics of embedded devices, we have adopted C/S architecture model, technically-based MVC framework, user interface, then uses a Qt (multi-platform C++Graphical User Interface) application framework for C/C ++as the programming language. The order system is running on ARM-based platform for Linux systems, the database used by the embedded devices in recent years, more popular SQLite3 lightweight database, the entire system is divided into three levels, driver layer, interface layer and application layer. Application layer includes orders for the system modules, system management. Interface layer is mainly database interface and the network synchronization protocol. In the driver layer, including the system hardware printers, CUP equipment, communications equipment, etc. drivers. The entire system from the design point of view clearly structured, branch clear, upgrade and maintenance excellence.At present the letter ETS intelligent terminal order system soon in Shandong, Shanxi, Fujian provinces and a number of places under the online operations, including the deployment of Shandong Province, is expected to be almost 1 million smart terminals at Qingdao, Zibo, and several other places online operations.
