全域物流跟踪系统中信号采集技术的仿真研究

Simulation of Collecting-Signal in Global Goods Tracing system

现代物流,是要实现物流工程系统的信息化、自动化、网络化、智能化和满足社会生产实用化的要求。通过构建高效物流平台,依据互联网技术使货物的生产进程、运输行程以及存取过程的全域信息共享。利用ZigBee无线通信技术构建了全域物流跟踪平台的网络通讯结构,以物流企业、生产企业的生产车间为单位进行设计安装,每个单位都组建一个网关、若干个ZigBee与传感器结合的无线读写节点,并依据LabVIEW的仿真输入通道辅助采集由电涡流传感器提取的全域物流内货物、车辆的有关信号。最后实现了互联网平台与全域物流系统中多节点信号采集的高效衔接。

Modern logistics is to satisfy the needs of social production, to realize the informationalization, automazation, networking and intelligentization of the logistics project system. The building of key technologies for high - efficiency logistics on globallogistics platform, such as common sharing of global information in the process of production, transportation and storing or withdrawal based on internet technology, collection of real time information about goods and vehicles by ZigBee node, the connection of nodal operation and logistical management platform by the network and common sharing of internet realizes the intelligent management process in the goods production, transportation and delivery center, namely the goods tracing in the global logistics system. The paper explains the tracing plat- form about goods and vehicles in the global goods system. Furthermore, the paper focuses on building vitural input system by LabVIEW. Via the virtual input system, the signals of the goods and vehicles are collected by electrical sensors, and the communication with the internet system is realized.
