摘要
针对我国目前冷链运输监测网络的不足,设计出一种基于RFID的冷链运输监测网络来监测车载终端的动态参数。该系统主要由车载终端和监测中心组成,车载终端由STM32F103RBT6中央控制器、GPS定位模块U-blox NEO、GPRS无线通信模块SIM900、RFID电子标签和读写器等部分构成,可实现车载终端数据的采集、分析、预处理、报警和监测等功能。监测中心可以无线接收、解析和在线显示温湿度和定位数据。实验结果表明,该系统性能可靠,硬件成本较低,能够实时监测车载终端的温湿度数据和车辆定位信息,适合在冷链物流行业推广使用。
In allusion to the shortages of the cold-chain transportation monitoring network, a RFID-based monitoring network is designed to monitor the dynamic parameters of vehicle terminals in this paper. The system mainly consists of vehicle terminal and monitoring center. Vehicle terminal is composed of STM32FlO3RBT6 central controller, GPS positioning module U-blox NEO, GPRS wireless communication module SIM900, RFID electronic tags and readers, and other peripheral circuit. The system can achieve functions of data collection, analysis, pretreatment, alarm and monitoring. Monitoring Center can wirelessly receive, parse and online display temperature and humidity, and location data. The experimental results show that the system has a high reliability characteristic and low-cost hardware. It efficiently accomplishes real-time monitor of temperature, humidity data and vehicle posi- tioning information, so it is suitable for use in cold-chain logistics industry.
