摘要
现有分布式光纤传感数据存储方法由于节点分布较为广泛,节点故障致使数据丢失现象常有发生,无法适应现今分布式光纤传感技术的发展与应用,故提出分布式光纤传感数据编码存储方法研究。依据现今光纤传感数据存储需求,结合网络编码与云存储优点,搭建基于网络编码的数据云存储架构,以此为基础,选取纠删码形式对分布式光纤传感数据进行编码,以数据编码结果为依据,设置数据编码容错机制(恢复丢失数据),执行容错机制后评估节点可靠性,动态分配编码数据,制定编码数据存储程序,实施程序即可实现分布式光纤传感数据的编码存储。实验结果显示:与现有三种方法进行比较,提出方法的容错率较高,平均为55.08%,网络能量消耗较低,平均为81.64 J,鲁棒性较高,充分表明提出方法的数据编码存储性能更好。
Existing distributed optical fiber sensing data storage methods are widely distributed, and data loss often occurs due to node failures, which can not adapt to development and application of distributed optical fiber sensing technology. Therefore, the research on distributed optical fiber sensing data coding storage method is proposed. According to today’s fiber-optic sensing data storage requirements, combining the advantages of network coding and cloud storage, a data cloud storage architecture based on network coding is built. Based on this, erasure codes is selected to encode distributed fiber-optic sensing data. Based on data coding results, a data coding fault-tolerant mechanism(recovering lost data) is set up. After implementing fault-tolerant mechanism, node reliability is evaluated, coded data is dynamically allocated, coded data storage program is formulated, and coded storage of distributed fiber-optic sensing data can be realized by implementing the program. Experimental results show that, compared with existing three methods, the proposed method has higher fault tolerance rate, averaging 55.08%, lower network energy consumption, averaging 81.64 J, and higher robustness, which fully indicates that the proposed method has better data encoding and storage performance.
