基于低能耗WSN的石油场站监控系统设计
Design of Oil Station Monitoring System Based on Low-power Wireless Sensor Network
摘要
Abstract
This paper presents a layered network structure merging with Wireless Sensor Network(WSN), General Packet Radio Service(GPRS) network and Internet to intelligently monitor the safety of the pipeline laid in remote station. WSN is build up based on WIA-PA industrial wireless standard. Clustered topology management is optimized, a low-power uplink protocol with extended super-frame for assigning timeslot is proposed, and an on-time downlink protocol of attaching timestamp to flooding protocol is implemented. Field data of three months trial running of the system and simulation data on OMNet++ platform have published good results of monitoring system with over 98% success ratio of data transmission, and WSN with energy balance in the every cluster and energy conservation of over one year lifetime.关键词
