The Design And Implementation Of Intelligent Multi-Media Supermarket Guide System

With the improvement of living standards,supermarkets are becoming bigger after constructing with more variety of wares and more abundant goods.So most consumers cannot find easily what they need in the supermarket.This not only causes the supermarket reduces the speed of goods circulation,but also causes consumers to influence user experience and waste a lot of time to search for goods.On the other hand,the large supermarkets mainly adopt the following ways in advertising: posters,rolling-play video advertisement and promotional advertising.These ways also have corresponding deficiencies.They nearly share the same fault: both of them can't exactly deliver appropriate advertising for customers.The present supermarket advertising system only broadcasts specific advertisements repeatedly.So they already cannot adapt to the requirement of the market information transmission.Therefore,building convenient shopping guide and multimedia advertisement system has become a mutual concern of merchant customers.As all said above,this paper proposes a new advertisement and shopping guide system for large supermarkets based on Ir DA(Infra-red Data Association)sensor network,which could overcome the defects of traditional supermarkets and greatly facilitate the consumer shopping needs.The paper focuses on researches as below:Firstly,this paper analyzes the principle of indoor position,and introduces position network based on single-chip microcomputer and Ir DA transceiver terminal to achieve the goal of accurate position with software system.Secondly,this paper introduces the overall solution of the guide system.This system uses TCC89 x processor(ARM11 core)embedded platform as the underlying hardware.This system utilizes embedded Win CE6.0 operating system as the software platform to fulfill the construction of the embedded system platforms.The active infrared pointing transmitter which made up of microcomputer and wireless infrared establishes itself to map the supermarket physical locations.It is possible for product positioning and shopping guide function,because of the locating network composed by hundreds of infrared pointing transmitters.Thirdly,the shopping guide system uses a modular design,and carries out the detailed functional design of this software system through the object-oriented design methods,based on the embedded system platform design,positioning terminal network and background service design.It completes the effective integration of user graphical interface with hardware platform,and achieves the entire intelligent multi-media shopping guide system.After repeatedly testing,the system is running well,achieved the anticipated target of the design stage.It argues the feasibility of precise positioning indoors in-depth based on wireless infrared sensor technology;On this basis,achieving the application and spreading of supermarket promotional advertising and position advertising.Therefore,it brings enormous economic benefits and social benefits for the supermarket.
