网络存储技术在水文监测中的应用研究

为了解决由于通信方式限制造成的水文信息数据丢失以及数据传输速度慢的问题,提出了一种将网络存储技术引入到水文监测系统中的方法.根据水文信息采集的实际情况,研发了一种适合在水文站运行的NAS服务器,然后提出了两种NAS服务器在水文监测系统中的组网方式,并进一步对这两种组网方式进行了分析和研究.最后通过模拟实验对定制的NAS服务器的性能进行了测试.测试结果表明,该NAS服务器能够满足监测系统对数据存储的要求.通过在水文监测系统中引入网络存储,能够有效地解决原始数据难以保存和调用的问题,同时能够有效地避免因为通信方式不可靠造成的数据丢失.

Application of Network Storage Technology in Hydrological Monitoring

To solve the problems of hydrological information data loss and slow data transmission caused by the limited communication ways,a method which applies network storage technology to hydrological monitoring systems is presented.According to the actual situation of hydrological information collection,a kind of NAS server suited for operating in hydrologic stations is developed.Then two network construction methods using the NAS server in hydrological monitoring systems are proposed,and analyzed and researched.Finally the performances of customized NAS server are tested through a simulation experiment.The result shows that the server can meet the data storage requirement of the station.By introducing network storage in hydrological monitoring systems,the problem of saving and calling the raw data hardly can be solved effectively,while the data loss caused by unreliable communication ways can also be avoided effectively.
