Data service method and device in vessel data integration system

Abstract

The present invention relates to a vessel data integration system and a vessel comprising same. According to the present invention, a vessel data request including a VDM path is received, and by using the received VDM path, the requested vessel data is searched from a database in which vessel data are stored. The VDM path may be an identifier hierarchically defining paths leading to each vessel data in a VDM, and each vessel data may be identified by the VDM path. Accordingly, necessary vessel data may be efficiently provided to various third-party services.

1 . A data service method in a vessel data integration system, comprising:
 receiving a vessel data request including a Vessel Data Model Path (VDM Path) from a service requester; and   searching for the requested vessel data from a database in which vessel data is stored, based on the VDM Path.   
     
     
         2 . The data service method in the vessel data integration system according to  claim 1 , wherein the VDM Path hierarchically defines paths leading to each vessel data on a Vessel Data Model (VDM), and each vessel data is identified by the VDM Path. 
     
     
         3 . The data service method in the vessel data integration system according to  claim 1 , wherein a data range in which to perform the search hierarchically changes depending on hierarchy level of the VDM Path. 
     
     
         4 . The data service method in the vessel data integration system according to  claim 1 , further comprising:
 identifying if the service requester has an access authority for a data range specified by the VDM Path,   wherein, as a result of the identification, when the service requester has the access authority, performing the search.   
     
     
         5 . The data service method in the vessel data integration system according to  claim 2 , wherein the VDM is generated by combining a vessel model, a system model and a data model,
 the vessel model defines hierarchical structure in an order of vessel, equipment group, equipment and component,   the system model defines hierarchical structure in an order of system, logical device and logical node for collecting vessel data, and   the data model defines hierarchical structure in an order of data object about structure of vessel data and data attribute about attribute of vessel data.   
     
     
         6 . The data service method in the vessel data integration system according to  claim 5 , wherein the VDM Path includes at least one name of equipment group, equipment, component, logical device, logical node, data object and data attribute. 
     
     
         7 . The data service method in the vessel data integration system according to  claim 6 , wherein the VDM Path has a sequential arrangement of at least one name of equipment group, equipment, component, logical device, logical node, data object and data attribute. 
     
     
         8 . The data service method in the vessel data integration system according to  claim 1 , further comprising:
 providing the found vessel data to the service requester in response to the vessel data request.   
     
     
         9 . The data service method in the vessel data integration system according to  claim 1 , wherein the searching comprises:
 in case of the vessel data request using a Query Application Programming Interface (API), extracting the requested vessel data by a Pull method, and   in case of the vessel data request using a Push API, receiving the requested vessel data by a Push method.   
     
     
         10 . A data service device in a vessel data integration system, comprising:
 a communication unit to receive a vessel data request including a Vessel Data Model Path (VDM Path) from a service requester; and   a search unit to search for the requested vessel data from a database in which vessel data is stored, based on the VDM Path.   
     
     
         11 . The data service device in the vessel data integration system according to  claim 10 , wherein the VDM Path hierarchically defines paths leading to each vessel data on a Vessel Data Model (VDM), and each vessel data is identified by the VDM Path. 
     
     
         12 . The data service device in the vessel data integration system according to  claim 10 , wherein the search unit hierarchically changes a data range in which to perform the search, depending on hierarchy level of the VDM Path. 
     
     
         13 . The data service device in the vessel data integration system according to  claim 10 , further comprising:
 an identification unit to identify if the service requester has an access authority for a data range specified by the VDM Path,   wherein as a result of the identification by the identification unit, when the service requester has the access authority, the search unit performs the searching operation.
