【摘要】 多温共配能够同时配送多种不同储存温度的食品,适合于市内配送发展的要求。然而,及时准确的获取配送食品的信息,有利于提高食品信息化程度,保证食品品质与安全。为此,本文针对多温共配的特点设计了适合于多温共配冷链物流的无线传感网络(WSN),网络包括了用于实时采集食品信息的传感器节点,和用于建立与维护网络的协调器。对网络通信性能、传感器节点功耗以及传感器节点在多温共配箱中的频谱测试,测试结果表明,网络能够工作稳定,通信可靠,传感器节点具有低功耗,可以满足多温共配冷链温湿度信息采集与监测的要求。更多还原

【Abstract】 Multi-temperature joint distribution can be used for distribution food at varied storage temputeratures,which is suitable for the demands of the city distribution development.A real-time information collection network was designed for multi-temperature joint distribution based on wireless sensor network(WSN),which can improve the informationization management in this field.A sensor node for collection tempterature and humidity,a coordinator for network organization ande data collection are included this work.Furthermore,the communication performance,sensor node power and the frequency spectrum of the node inside the distribution box are tested.The result showed that this network is stable,reliable and seneor node consumption is very low.Therefore,this net work can be potentially used in collection and monitoring data of temputerature and hunidity for multi-temperature diatribution food.更多还原
