Design Of The Library Management System With The Technology Of CDMA And RFID

With the development0f modern information proccssing technology,the library also toward automation, networking and digital direction. But the most basic resources of the library system is still tube hiddell literature,especially the paper documentation；to provide readers with the most important way or services and content,but also the collecuons data. As a result of artificial management of collections information and more timc-consuming cffort,but more cumbcrsonle to manage,so the automation of libraty management is to achieve good practieal signifcance.Existing library bar code identifieation is the main way of management,not only in the management of labor-intensive process and a waste of time, can not be intelligent management,library management and ineffnicient.Management of library automation,networking,digital intelligent technology and researcll libraries is the fundamental way to solve this problem.In vicw of radio frequency identification technology has identified distance,large amount of.information,confidentiality and good featurcs,so to apply it to the library management is an ideal choiee.Do not use radio frcqueney based technology not only redicess the loss rate of books,shelves improved proeesses, simplified light administrative tasks, so that readers automatically Borrow.and can speed up the recognition speed,casy to read,to spced up invcntory tasks.Thcrefore,the use of radio frequency identification teehnology can bring a lot of library management casy.In addition to use radio frequency technology to tag information collected books, but also consider the system of communication.At present the use of fmore means of communication are:RS-485bus and CAN bus.The system uses CDMA as a means of communication to avoid paralysis of the entire system all the way wrong question,in addition,can improve communication quality and communication rate.CDMA communieation method is more stable than the CAN bus communication.transmission distance and transmission rate is also higher,to achieve the wireless communications,while avoiding the paralysis of the entire system all the way wrong qucstion,therefore,this paper uses CDMA as a means of communication.This artiele deseribes the purpose and signilicsnanee of the research topics and research status, describes the radio frequency identification technology, elaborated based on CDMA technology, library management system’s overall design, introduces the reader based on CDMA technology, hardware design and software design and simulation. Part of the radio frequency identification technology, this paper describes the development of RF technology based not historical, system components, the system’s basic work processes, the classification system, the system works and system applications. Part of the overall system design, gives the overall system design block diagram. In the hardware design part of the reader, the reader hardware cireut was given. In the software design part, this thesis describes the software design, and shows the software flow chart.This thesis for the purpose of achieving the efficient management of the library,and Integrated use of radio frequency identification technology, CDMA technology,and so on. This system Effeetively solves the complicated problem of library management, improves security and operational efficiency of the library management, which makes the library management more intelligent, digital, and Personalization.
