摘　　要：该文为了记录舰艇内出入各个舰舱的人员情况,设计了一种基于射频识别RFID(radio frequency identification)的无线身份识别系统,对监测的人员信息进行无线传输。运用n RF24LE1芯片设计的电子标签IC卡(integrated circuit card,集成电路卡)每隔2 s向外发射自己的ID(identification card,身份识别)信息和校验码,当携带有电子标签的目标进入舰舱时,该舰舱内置的双通道RFID接收器就可以接收到信号,接收信号的距离可通过HMC274调节接收信号的增益来控制,经过实验测得该系统的有效距离的范围为0.3 m^11.4 m。接收器将接收到的信号通过串口传递给STM32中央处理器,STM32中央处理装置通过串口和上位机相连,上位机用Lab VIEW完成的界面可随时查看各个房间的信息。In order to record the information of the person who has access to the ship cabin,a wireless identification system based on RFID（radio frequency identification）was designed. The system is based on RFID technology,which is used to translate the information of monitored people. The electronic tags IC card which is designed by n RF24LE1 chip transmit the card＇s ID and check code for every 2 s,when people carrying the electronic tag get into the ship cabin,the binary channels RFID receiver can receive the information,and the distance of receiving signal can be controlled by adjusting the gain of HMC274. The range of effective distance measured through experiment is 0.3 m～11.4 m. The receiver will transmit the received signal to the central processor STM32 through the serial port,and STM32 is connected with the upper computer through the serial port.Through the interface of the upper computer that is accomplished by Lab VIEW,we can check the information of each room at any time.
