Based On Windows CE Identification Of Mobile Radio Equipment

Radio Frequency Identification efficient information system is the information identification and collection system.It has a characteristics of non-contact.It can identify a number of target devices at the same time.Which Indetifies the high-speed movement of objects with strong anti-interference.In very poor conditions of work,the strong confidentiality of the characteristics,will still be very effective.Therefore,the technology has been applied to many practical areas,such as aviation,logistics and finance.In recent years, the development of wireless identification technology is better than before.As a result of the application of RFID technology in the new practical system,it promotes new theoretical and applied fields.In recent years,as well as semiconductor chips with the development of semiconductor technology to the embedded computer technology as the core of embedded systems development has been rapid.Embedded systems based on RFID technology has become an inevitable trend.However,the current domestic market for RFID systems which only based on the 8-bit,16-bit microcontroller used embedded operating systems very little,moreover the function is very single.With the system increasing the complexity of the expansion of the scope and application,the system without RFID would expose more shortcomings than ever before.At the same time,The development of IT technology is no longer confined to the functions of personal things and the increasingly powerful features and prices are falling. Making hand-held terminals in various fields has become an increasingly widespread applications.In public security,hospitals and insurance industry,IT technology has a lot of application cases.At present,the application of a handheld terminal is very limited,but people have been more interested in this industry.Because the price of hand-held terminals and portable is falling,the development of 3G,so how RFID will be synchronized with the handheld terminal development and the development of computer technology has become the hot spot.In this paper,based on the structure of 32-bit ARM microprocessor,we designed a RFID reader system which is visualization,multi-interface,multi-protocol supporting, modular and more easy to expand.The introduction of the powerful real-time embedded operating system for the development of multi-function,hand-held RFID reader devices provide a good reference to the popularization and application of RFID technology with a certain degree of practical value.In this paper,first of all the topics on this subject briefly described the technology background,and then outlined the purpose of the study subjects which containes the meaning and status of research at home and abroad.And then,I discussed the RFID technology and the embedded systems,so as to lay a theoretical foundation for the study..After that,I began to construct the entire development platform which includes the structure of hardware,the RFID reader system and the main function of the analysis methods.And then gave a briefing on the RFID reader hardware including the testing methods and processes of the software system. Then by comparing the options,I used Visual Studio 2005 tool to handle the platform development terminal applications and the embedded database.After the completion of the design,we develop its database,and the finished the communications with the background database.First of all,the development of applications was applied on the simulator,and finally downloaded to the hardware platform for testing.This highly versatile system whose hardware and software on the system with some slight modifications can also be applied to other systems.This RFID reader system used Samsung S34210A micro-controller and the Windows CE 5.0 Operating system.The system can effectively identify the MF 11C S50 RFID card to read the data and sent the controller through the serial port terminal.RFID can read and write data which can be storaged with the distance of one centimeter.Basically reached a low power,small-scale development of the target.At the same time,this article also designed an detecting radio equipment management system.In accordance with the company's needs, we use the B/S structure and modular development methodology.First of all,we desinged the interface,After that,we began to desinged the different functions that is the modular design,which includes 8 modules:(1)System management module:modify passwords,rights management.(2)Database backup:the backup timestamp technology.(3)System log:view system information,error reports and so on.(4)System settings module:set up public information,land-based stations set up,the land of Taiwan parameter setting,parameter setting functions of radio stations.(5)Detection equipment modules:wireless radio(station) set up the application,technical information on setting an application to apply for technical information,equipment testing.(6)The task management module:a new task,task information, task summary,generation of task statements,mission statements and print statements for format conversion support,(7)Integrated information query:query results according to conditions,you can print statements,and to support the statements format conversion.(8)Statistics:in accordance with the conditions of the distribution of generation facilities and equipment statements for the year statements,print statements and statements to provide format conversion function.The next database design and data synchronization. Database designing used the national radio station database designing standards.And in accordance with this standard form from its design field.So as to achieve a safe and strong, persistent database.Subsequently,the last part ofthe company's project development of the requirements the synchronization database.Designing goal is to connect PDA and PC through USB line,synchronizing the data and updating the database.This demand is operated through producing and subscripting snapshot technology to complete.National radio stations as a result of the database used Oracal and our database design of the system is used by SQL Server 2005,so that it may not be the common standard.However,SQL Server Mobile database is more conveniently used for such mobile devices and cell phone,so I used the the SQL Server 2005 tool to develop the databases.Finally,the article summarizes issues and prospects.
