基于无线传感器网络的智能物流车辆监控系统的设计

摘要

为了解决物流运输途中物资安全监控难、受限人为因素等诸多安全隐患问题，并能实现对物流车辆定位、实时监测和跟踪功能，介绍一种基于无线传感器网络的智能监控系统在物流车辆调度监管中的应用。设计以S3C6410微处理器和WiFi模块及GPRS等构建的无线传感器网络节点，实现对物流车厢内物资信息的采集、处理和显示，异常时启动摄像头进行实时监控，并可将车辆的工作状态与位置等信息传输至监控中心。在VMware和Ubuntu11．10开发环境下编写和编译传感器节点程序，实现无线传感器网络节点之间的数据传输功能。结果表明：系统工作稳定可靠，结构简单，功能易扩展，具有推广和应用价值。%In order to solve many safety risks of in-transit logistics transportation such as goods safety monitoring difficulty and constrained human factors, as well as to realise the functions of positioning, timely detecting and tracking the logistics vehicles, we introduce the application of a WSN-based intelligent monitoring system in logistics vehicle scheduling and regulatory services.We design the wireless sensor networks nodes constructed with S3C6410 microprocessor, WiFi module and GPRS, etc., and implement the collection, processing and display of goods information in transit.Once the abnormal situation occurs, the cameras installed in vehicles will work to carry out real-time monitoring and send back the information of the vehicles working condition and position to monitoring centre.In VMware and Ubuntu11.10 development environment, the sensor-nodes programs have been programmed and compiled, which realise the data transmission function between WSN nodes.Test results show that the system works stable and reliable, its structure is simple, and its function is easy to be expanded, thus has the popularised and applied value.
