基于SD-WSN的高危仓储无线监测系统

针对高危仓库区域分散和结构复杂的特点，设计一种基于软件定义无线传感网络(Software Defined Wireless Sensor Network, SD-WSN)的高危仓储监测系统。系统由传感节点、控制器和监控软件组成，传感节点根据流表的匹配规则采集环境信息，控制器集中管控路由策略和传感任务，监控软件收集环境数据并图形化显示。同时，终端用户能够根据控制器提供的接口制定传感任务，以更新流表的方式实现节点功能的重新配置。测试结果表明：该系统具有可编程的特点，能够实现对不同安全指标的灵活监测，同时具有良好的通信可靠性。

High-risk Warehouse Wireless Monitor System Based on #br#Software Defined Wireless Sensor Network

Aiming at the wide-region distribution and high complexity of the high-risk warehouse, a safety monitoring system based on the software defined wireless sensor network (SD-WSN) is designed.The system consists of wireless sensor nodes, controller and monitor software.In order to monitor environment inside the warehouse, the wireless sensor nodes are used for data acquisition by matching the flow table, the routing protocols and the sensor tasks can be configured by the central controller, environment data can be collected and graphically displayed by monitor software. In addition, monitor system can formulate sensor tasks through the interfaces provided by the controller. The reconfiguration of sensor nodes can be realized by updating the flow table. The testing results indicate that the designed system is programmable, can monitor the various safety indicators, and has good communication reliability.
