Design And Implementation Of The System Of Vending Machine For Box Lunch Based On3G Network

With the quickening pace of life and people look forward to improving the quality of life, the lunch is an urgent problem to the majority of working-class in the urban. Therefore, the industry of fast food ordered online rises rapidly across the country. With the situation that the number of people live in urban is larger than that in rural and there is a huge demand of the lunch for the working-class in the city, so the traditional online ordering style which is that the consumers order the food through the website or telephone and then the catering company deliver it to the consumers by the staff cannot meet the demand now. In allusion to this phenomenon, this paper presents a new type of intelligent self-service system of vending machine for box lunch, the using of this system can make up for the shortcoming from the traditional online ordering. The system consists of management platform system and vending machine terminal system, the communication and coordination between the two parts is based on3G wireless network. This thesis focuses on the terminal software system of the vending machine for box lunch.Firstly, this paper introduced domestic and international research on vending machine, on this basis, as well as combining with the specific case about the dinning problem of the general urban working-class, it discussed and analyzed the research meaning of this topic. It also analyzed the main points of the system design and the key technologies used in the design. Then, from the system design target and principle, it gave a detailed introduction about the overall design of the system, which including the following aspects:overall structure of the system, logical function process, IC card process and3G wireless transmission, etc. Then, it made a brief introduction about the development platform of the system, windows Xp, and the development tool, Visual C++6.0. On this basis, it detail explained the design of system database and the concrete implementation method of each part. It also introduced how each system module integrates through serial interface. Last, the paper showed some of the functionality on system running and described the practical application situation of the system, pointed out the deficiency of the system and presented the improvement ideas.The system has already been put into trial in Beijing and Shanghai. The result shows that this system can effectively alleviate the dinning problem of the urban working-class, improved the service quality and increased the service efficiency. This system could also provide some certain reference to the implementation of other related self-service systems.
