中文摘要：

采用无线微处理器JN5139构建基于Zigbee协议的无线监测、定位网络，并结合低功耗MSP430系列单片机与NRF24L01构建的有源RFID构建一种全新的集装箱监测系统。系统工作性能稳定，检修方便，运行成本低廉，有效解决了RFID系统的信号碰撞问题，以及WSN无法获得目标详细信息的问题。将其应用在港口货场，可实现港口的信息化和自动化。

英文摘要：

The new container-monitoring-system is built on a network and an acfive-RFID -system. We use JN5139 wireless microprocessor to build the monitoring and positioning network based on the Zigbee Protocol and use low-power MSP430 MCU and NRF24L01 to construct the active-RFID. The system has the advantages of stable work performance, maintenance convenience and lower cost. It effectively solves the problems that RFID system＇ s signal collision and WSN can＇ t get the detailed information of the target. Using in port freight yard, it can realize the information and automation.
