基于ZigBee的货运动车组货物全息状态监测系统
The Monitoring System for Cargo Holographic Status in Freight EMUs Based on ZigBee Technology

为了保障250 km/h以上货运动车组的承运货物的安全，需要对集装箱全息状态进行在线监测及预警。本文设计基于ZigBee技术的货物全息状态在线监测系统，实现集装箱内温湿度、氧气浓度、加速度等信息的采集及预警。首先进行了货运全息状态监测系统的总体方案设计，然后针对车载单元和地面数据与信息处理中心分别进行硬件和软件设计，并完成系统原型的搭建。测试表明，系统具有耗电低、自适应性优良、鲁棒性强等特点，达到了货运动车组货物在线全息状态采集与监控的目的。
In order to ensure the safety of cargo transported by 250 km/h EMU, it is necessary to monitor and warn the holographic status of containers online. In this paper, a cargo holographic state online monitoring system based on ZigBee technology for realizing the collection and early warning of information such as temperature, humidity, oxygen concentration and acceleration in the container is designed. Firstly, the overall scheme of the holographic condition monitoring system for cargo transport is designed. Then, the hardware and software of the vehicle unit and the ground data and information processing center are designed respectively, and the prototype of the system is built. The system-test results show that the system has the characteristics of low power consumption, good adaptability and strong robustness, and the purpose of on-line holographic state acquisition and monitoring of Freight EMUs is achieved.
