AV8 is applied to ship
Abstract：It adopts modern wireless communication network technology,information technology to build ship to shore integration monitoring system platform, it can satisfy modern shipping enterprise’s real-time,safe,effective and low carbon requirements.
With the development of marine power plant and other equipments enlargement,automation and intelligent direction, fault diagnosis and maintain for ship equipments become very hard.When the ship is on the sailing,if the equipment is broken,the supplier and maintainance center cannot give the technology support in time.Many complicated problems,the sailors cannot solve.
According to the characters of ship to shore communication, ship to shore integration monitoring system mainly consists data acquisition and processing system,Shore-based management application system and ship to shore communication system.
Data acquisition and processing system:
Only the ship-base data acquisition and processing system are stable,safe and in time, the ship to shore integration monitoring system can be used for managing ship.
Data acquisition and processing system can be divided into two layers network structures,the up layer is POE,the down layer is field bus network. The up layer adopts POE network structure which connect the man machine interaction station and server for data storage and processing.The down layer adopts field bus way which connect the data acquisition modules and communication modules,these modules are for data acquisition,analysis and processing.Gateway is the data transmission of these two layers,gateway is the core of data transmission system,it mainly analysis,processing and summarizing the data from down layers.The data after processing can be transmitted to the shore-base application system,it’s convenient for the shipping enterprise to monitor the ship operating situation and using situation.Besides,the data also can be transmitted to captain,sailors by whole ship network information system.
Shore-base application management system:
Shore-base application management system platform is the core for enterprise information processing and decision.The data through the ship to shore communication system enter to the shore network information platform, the data server will verify and separate the data and then programme the data to the relative data base.The ship data and other relative data will finally assemble to the shore-base network information platform, different client terminals can call database and transfer the ship data to the administration person on the shore,the administration person also can transmit the newest information and orders to the running ship by the system, so the operation companies can control the running state of ships.
Ship to shore communication system:
For a long time,the data share and transmission is a big problem for ship companies.Before,mailing compass is the way to transmit data information,there is no timeliness. With the development of information network and communication technology, people is searching reliable ship to shore communication technology to realize the fast,safe and accuracy information transmission.Ship to shore communication system adopts different communication equipments according to operating environment and operating requirements.Marine satellite Inmarsat--F station,Inmarsat--C station,microwave,telecom network are as known to all.
