Fault detection method based on file naming algorithm for ocean observing network

Ocean observing network is foundational facility for marine disaster prevention. Base on the file naming algorithm of ocean observing data, a fault detection method for ocean observing network is proposed in this paper. By analyzing file naming and storing rules of ocean observing data, the file naming algorithm is designed. Further, the data receiving exception can be detected and located to the data source node by executing file naming algorithm. Last, combining with network circuit detecting result, the fault type can be distinguished and the faulty object can be located precisely. For illustration, a fault detection example with minutely data files is utilized to show the effect. Empirical results show that the fault detection method based on file naming algorithm can locate the faulty object in 10 minutes, and can provide operation protecting for ocean observing network.
