Design And Implementation Of Intelligent Quick Guide System Based On ARM

In recent years,with the large-scale,multi-layered and diversified supermarkets,the problem of shopping for goods and checkout has become increasingly prominent.In order to solve these two problems,the system combines the innovation of the off-line supermarket built by Alibaba and Jingdong,as well as the Internet technology and Internet of Things technology,and proposes an ARM-based,safe and fast Intelligent Purchasing System.This system is an intelligent shopping guide system consisting of cloud server,shopping guide car,Wechat applet and mobile web page.The cloud server mainly manages the supermarket database;the shopping guide car provides real-time weather information,advertisement video broadcasting and quick payment functions;the Wechat applet provides real-time weather information,commodity purchase,commodity advertisement display,longitude and latitude positioning,calendar query and other functions;the Wechat applet provides real-time weather information,commodity purchase,commodity advertisement display,And calculator functions;mobile web pages provide real-time weather information,commodity advertising display,news viewing,video playback and music playback functions.And the system boldly conceived the use of small programs or mobile web pages for remote control of supermarkets,to achieve real easy management of large supermarkets.The purpose of this system is to provide consumers with a comfortable,fast and relaxed shopping environment,so that consumers have a better shopping experience,while reducing the cost of supermarket management and simplifying the supermarket management process,so from the two aspects of consumers and businesses,both have good commercial value and practical value.The business model of this system is based on the mobile internet's O2 O mode.Compared with the current domestic intelligent supermarket only focuses on offline service mode,this system pays more attention to offline and offline services for consumers at the same time.Online services include Wechat applets and mobile web pages,which provide customers with the latest advertising information,commodity information,supermarket management and entertainment services;offline,the main carrier is the guide car,the main function of the guide car is to facilitate shopping and data acquisition,the sensor on the guide car is used to collect and process data,and through the network,the data is uploaded to the cloud server.In this way,Wechat applets and mobile web pages can access the data of cloud servers,thus realizing data sharing and sharing.This system is mainly implemented through three parts: cloud server,car guide and mobile phone.1.The cloud server uses Tencent cloud server.After purchasing the cloud server,Apache service is used for network access,FTP service is used for file transmission,MySQL database is used for background database,and Tencent cloud platform provides high-speed and stable cloud service.The content distribution network CDN service provided by Tencent cloud is applied to avoid requests from receiving regions,bandwidth and clothing.High latency and low availability caused by server capability and other factors;2.The guide car is equipped with Linux+QT operating system and supports WiFi module,which enables the guide car to transmit data to the cloud server by connecting WiFi.The core controller of the guide car is Samsung S5P6818,which belongs to ARM Cortex-A53 architecture.3.The mobile terminal is composed of two parts,Weixin applet and mobile web page,which are easy to use,easy to operate,rich in content and unlimited in code.Therefore,the system gives full play to the advantages of these two platforms,making the system more colorful,more convenient and intelligent.People can access the web pages of servers by connecting to Wifi or mobile data,as well as access the Wechat applet and pay attention to the Wechat public number to obtain commodity information.
