Design And Implementation Of Shipborne Terminal Warning Prompt System Based On Maritime Cloud Location Service

The sea area of our country is vast,the marine environment is different from the land,maritime disasters such as typhoons and tsunamis are inevitable,because of lack of location information,it has a great impact on search and rescue and lifesaving.If the positioning chip is embedded into the object to be located,such as pier,life jacket,life raft,fishing net,buoy,hydrophone,cable and so on,after collecting information from the collector,then location data through the network into the cloud platform,the cloud platform calculates and transfers data to the mobile terminal,thus,when the ship is in danger of collision,mobile terminals can remind people to take action in a timely manner,improving navigation safety.Therefore,the dissertation proposes a maritime cloud location service and mobile security prompt system,cloud location is to store location information stored on the cloud computing platform,cloud location services are location information that is calculated on a cloud computing platform to provide service to ship terminals,mobile security prompt system is when the ships is in danger of collision,The phone will automatically alarm prompt.There are two broad categories of system data flows:maritime positioning data via the network,transport to cloud platform;The cloud platform transfers the processed data to the terminal.The main work of system development is to build OpenStack cloud computing platform;Ship position data analysis;The design of the database storage position data;Build a ship ad hoc network,realizing network communication;Developing Android mobile security prompt system,understanding the process and situation of ship collision avoidance,analysis of factors affecting collision avoidance,use collision avoidance formula,realize mobile phone sound alarm prompt function.Finally tested,the system runs normally...
