In recent years, as mobile payment in China's development of more and more rapidly, more and more stores no, no vending machines, more and more demand for mobile terminals have become more sophisticated, how to reduce these devices the development threshold, so that more and more people in their daily lives may be more exposed to this type of product, performance and lower development threshold for terminals put forward higher requirements.
1. vending machines (Vending Machine, VEM) is automatically according to the consignor coins into the machine. Vending machines are commonly used in commercial automation equipment, it is not limited by time, place, and can save manpower, convenient transaction. Is a new commercial retail form, also known as 24-hour mini-supermarket.
2. vending system concept and system principle : common major schools, shopping malls, as well as more local crowd is host control, emergency power supply by the intelligent, payment systems, data download, network operators, multimedia displays and other external set consisting of a set of sale payment system.
The system has a man-machine interface, data exchange can be realized with the person terminal and the server in conjunction with a host system, including the system state, system failure, feeding channel failure, out of stock, the sales data vending machine mounted on GPRS transmission module wireless or other means to the vending machine network server, operators can grasp the information vending machine on any computer networked to achieve large-scale vending machine operators and network management.
3. The vending system control features and a host program to achieve: a host of interactive operation support software, responsible for analysis underlying device, fault status information, to receive information from human-computer interaction.
Features:
❶ customer, the system can according to the wishes of the operator, transforms the guide interface guides the user, in order to achieve rapid operation.
❷ when the sun is too bright, then the device will look conventional screen; this intelligent system capable of near or reaches a predetermined valve, voice, automatic brightness adjustment features such prompt, prompting the operator to avoid errors.
Program requirements and implementation
■ serial (RS485): on the one hand by the intelligent system control host own RS485 communications interface for easy connection with other devices, mobile devices collect a variety of information.
■ Display: Display UI interface, you can display the status of each of the goods and payment information, user-friendly interface.
■ WiFi / 4G: networking. The system devices are linked with the server host systems, including the system state, system failure, feeding channel failure, out of stock , the trend of things.
Recommended Scheme 1: 4418 development platform - to provide information on hardware and software design, easy product development.
Recommended Scheme 2: 4418 touch one machine - all calls to provide the source code interface, and provide routine DEMO- only need the upper application.
Xun 10.1-inch touch one machine, using the 4418 core board to support the entire network 4G, Bluetooth, rs485, can, Ethernet module.
