Based on polling mechanism,the design of the RFID reader system gets the data of active RFID cards from four RFID readers,respectively.The system uses the Visual Studio C++ 6.0 programming language and MS SQL Server 2005 database technology to realize the communication between the COM port and the RFID reader,RFID card configurator and ID card readers through the WINDOWS API and CSerialPort class library.By matching the data record in RFID readers and in RFID card configurator module,the personnel location can be obtained in real time to realize the personnel orientation and management.The practical application shows that this system can finish acquiring and updating the data fast and stably,and effectively solve the orientation problem of the persons far from scenic spots.
