摘要
为了提高光纤安防系统的误报率,需要同步采集多个监测节点的数据。基于同步采集需求,设计并实现了一种基于PXI总线数据监测系统。系统采用多节点分布式布局方式搭建了监控网,并通过IEEE 1588协议实现各监测节点数据的同步采集,以及将各监控节点采集的数据通过GPRS网络传送到监控中心。实验证明,系统可实现纳秒级同步,有效解决了多分布点同步采集数据的难点,为后续的算法优化创造了有利条件。
One of the most important indicators is false alarm rate in the optical fiber security system. To improve the system,we should collect synchronization data of multiple monitoring nodes for Hadoop. Considering the demand,we design and implement a distributed data monitoring system based on PXI bus. Multi-node distributed layout monitoring network is set up in the system, and it achieves synchronous data acquisition in different monitoring points with 1588 protocol. All data is sent to the monitoring center through GPRS. The experimental results show that the system can realize nanosecond level synchronization, which can solve the difficulty of synchronously acquiring data at multi-distribution points and create favorable conditions for subsequent algorithm optimization. The system can be applied in the optical fiber based security system.
