Design And Implementation Of The IOT Platform Of Vending Machine Based On2D Bar Code Payment

As a new kind of Commercial mode of retail, Vending Machine is used by more and more people for its characteristics of convenience, fashion and24h-service. Along with the further development of our country’s economy, science and technology, social demand for vending machine will be rapid growth. Under this trend, vending machine operator and manufacturing faces enormous opportunities for development, but also will face how to efficiently manage the increasing scale and scattered deployment of vending machines, in order to improve the vending machine operation and the management efficiency. In this background, this paper puts forward comprehensive use of sensors, database, wireless communication, automatic recognition and network technology to build the IOT platform build by vending machine.The system by means of sensors,3G, network, database, and many other IOT technologies, to achieve real-time perception, remote monitoring and management of the vending machines, and supply multi-dimensional statistical analysis of operational data. Based on the qr code technology, the mobile phones payment can Make up for the deficiency of the cash payment in the vending machine shopping.This paper first introduces the development and application of the IOT, vending machine and2d-bar code, discusses the research content and significance of vending machine platform based on IOT and mobile payment methods based on mobile phone2d-bar code. And then put forward the design goals and design principles of the system, and on this basis, put forward the software and hardware architecture of the system, with high scalability and high data processing ability. And the database and mobile payment scheme based on2d-bar code is also designed. Then, the related technology used in this system and the specific realization of each function module of the system are described. Finally, summarize the full text. The inadequacies of the system is analyzed, the next step work is also referred. At present, the vending machine platform based on IOT, have been put into operation. Through it, operators have realized the centralized management of vending machine and can grasp the status and sales information for each machine in real time, greatly improves the operation and management level. In addition, the payment scheme based on2d-bar code proposed in this paper is proved feasible and has a certain practical value.
