Abstract: The monitor system of the fresh logistics transportation system based on wireless sensor networks enables the real-time tracking and quality control of products. The traditional monitoring system needs to transmit the sensor data to the control center in real-time and it would cause the overload of data links and communication systems and reduction of data acquisition and transmission efficiency. This study aims to design a wireless sensor network monitoring system of fresh logistics transportation. By using the compressed sensing technology, the data sampling rate is reduced effectively to reduce the system pressure. Test results show that this system can accurately and efficiently recover the data collected by sensors and feedback the goods temperature variation throughout the fresh logistics in real-time to provide effective regulation and the security guarantee for the transport of goods.

摘要： 基于无线传感器网络监控的生鲜物流运输系统可实现的产品实时跟踪和质量管理。传统监测系统需要运输车辆将其传感器数据实时传输到控管中心，可能导致数据链路和通讯系统超载，反而减少数据采集和传输效率。该研究旨在为生鲜物流运输设计一套无线传感器网络监控系统，使用压缩感知技术有效降低数据采样率以减少系统压力。测试结果表明该系统能够准确、高效的恢复传感器采集的数据，实时反馈货物在生鲜物流各个环节的温度变化情况，为货物的运输提供有效监管和安全保证。
