The structure of the vending machine control system is announced!

1. Main control system 　　 The main control system is the brain of the vending machine, which controls the operation of all parts of the machine, including delivery mechanism, lighting, compressor, electric heating, buttons, cash module, and various detectors.　　 Before the Internet entered, vending machines operated in a pure master control system for decades. Fuji Electric's old-fashioned vending machine manufacturers have accumulated rich experience in this area. The current large-scale production model is based on the continuous improvement of the master control code of the past generations. Especially for the control of the sales process, the timing control of each component and the increasingly important energy-saving control, it has great advantages.　　 In recent years, with the entry of the Internet of Things and the Internet of Things, the original main control system is also facing updates and changes. The biggest change is the transfer and simplification of functions. In the past, many functions from host control have been transferred to industrial control and even to the cloud. Many manufacturers only install the control panel on the machine and send commands directly from the industrial control to the control panel.　　2. Industrial control systems Industrial control systems had application scenarios before the arrival of the Internet era, such as offline card payment, wired/Bluetooth printing, near-field data collection, screen product selection, and so on. However, large-scale applications and outbreaks have developed rapidly after the Internet entered, from the earliest simple DTU (data transmission module) to electronic payment to various types of human-computer interaction.　　The main functions realized by the industrial control system are: various electronic payments, human-computer interaction interface, screen display control, data acquisition and reverse control, etc. At present, the mainstream industrial control operating system is Android, which accounts for more than 90%, and there are some WINODWS systems and LINUX systems.　　Industrial Control has now replaced the master control and has become the 'brain' of the new vending machine, controlling the sales process, payment, price setting of the goods, data storage and so on.　　3. Communication system Communication system is particularly important in today's era of Internet of Everything. The current common perception is that each vending machine is regarded as an IoT terminal, connected to the world. On this channel, data is running, and communication between the vending machine industrial control and the cloud server is realized.　　All interactions must be safe and reliable. Security refers to ensuring that data is not stolen, tampered, or forged by means of terminal identity verification, data algorithm encryption, etc.; reliable refers to ensuring that high-order equipment is always online, high-order concurrent processing capabilities, automatic migration of service failures, etc. . The current common practice is to rent cloud servers and adopt a more mature IOT architecture. Compared with self-built servers, it has many advantages and conveniences. (I have the opportunity to explain this in detail later).　　As for communication modules, most of them currently use 4G.　　4. Background processing system The background processing system is generally set up on a cloud server, which is the computing and processing center of big data. The data uploaded by each vending machine through the communication system will be parsed, analyzed, processed by various programs and stored in the corresponding database.　　Some need to respond automatically. For example, if the user pays but the vending machine is not shipped, the refund must be automatically made; if the fault and abnormal information is found, it will be automatically pushed to the operator, and so on. In addition to the real-time processing after receiving the data, the background processing system is also responsible for regular and irregular big data operations, such as automatic calculation of statistical reports for the year, month and day, automatic calculation of machine inventory and replenishment numbers, and automatic calculation of the sales ranking of each product , And various AI smart recommendations.　　5 Operation Management System The operation management system is divided into two parts: the consumer side and the operator side.　　 On the consumer side, it generally has functions such as shopping payment, membership system, card management, and consumption detailed billing. This part of the function can also be achieved through direct connection to payment platforms (such as Alipay, WeChat). More importantly is the part of the operator. Operators need to manage their vending machines through the management system: check machine status, check machine failures, understand sales, check inventory; 　　 guide operations through the system: how often to replenish , How many goods should be brought each time, when replenishment does not affect sales, which points have good sales, which products should be eliminated, and how to match the goods channels; 　 handle after-sales through the system: how to accept complaints, how to check bills, how What to do if the person is not on-site after refunding the goods; 　　 Set the machine through the system: how to set the cargo lane and display window, how to set the price and discount, how to adjust the temperature uniformly and quickly when the season changes, how to set the compressor and Energy-saving lighting; 　　 manage operations through the system: how to know the efficiency of the replenisher, how to control the quantity of goods, how to calculate the recovered cash, how to reconcile electronic payments, and how to obtain machine sales data.　　 The back-end management system is very important to operations. A good system can reduce operating costs, improve operating efficiency, increase user satisfaction, and improve operating efficiency.　　 This article is organized by a vending machine, this article does not represent the point of view of this site Previous article: Is the price of unmanned vending machine expensive?
