用于内河船舶管理的主动式RFID电子标签设计

摘要

In southeast coastal area of China,there are lots of lakes and rivers.Water transport is an important freight transport mode.Facing the great mount of ships,the government need a new method of ship management to decrease the cost of human resource and oil.This paper introduces a design of the active RFID tag used in inland ship management.The tag is composed by MSP430F2012 and nRF24L01 RF chips.Its working frequency is 2.4 GHz.The tag＇s size is small,and it can alarm when it is dismounted illegally or its battery is on low level.Through the measurement in the rivers,the reader can steadily scan the electronic tag tested within 500 meters which meets the design standards.%我国东南沿海地区,河流湖泊众多,水网密集,船舶作为内河航运的重要货运载体,具有很大流动性。为了改变现有的管理模式,降低人员成本和监查艇的燃油费、维修费等目的,设计了一种适合于内河船舶管理的主动式RFID电子标签。这种电子标签由MSP430F2012微控制器和nRF24L01射频芯片组成,工作频率为2.4 GHz,体积小巧,具有非法拆卸报警、低电量报警等功能。经过在内河中的实测,在500 m的范围内读写器可以稳定扫描到被测的电子标签,符合设计标准。
