The Implementation On The Rights-protect And Law-enforce Buoy Of Embedded Ethernet Gateway

In recent years, along with the ocean resources more and more get the attentionof the world common between countries, the growing territorial sea dispute.Ourcountry has in southern and eastern continental coastline of more than18000km, theterritorial sea area (including the inland sea and marginal sea area of about470squarekilometers.In such a vast sea areas in the world to safeguard state and the people’sinterests are not violated is a very difficult task.Marine rights protection law enforcement buoy is based on the present operationof the large ocean data type buoy installation high resolution image acquisition systemand acoustic sensor array, the key point for sea ship information, improve all weatherdetection, obtain Marine tort target ability; Based on the developed respectively buoysatellite high speed data real-time transmission system, realize the goal of tortcharacteristics identification and judge; The detection technology, integratedtransmission technology and analysis technology, the judge, in the east China seaactivities in sensitive area demonstration application, through the surface andunderwater surveillance, monitoring for rights law enforcement to provide emergencysecurity technical support. Buoy in far away from the land of the sea, the environmentis bad, the buoy monitoring to real-time acquisition and accurate sent to shore consoleto take timely measures to implement rights is a must solve the problem. Ethernet andthe traditional serial communication phase comparison, has the communicationdistance, communication quality is stable, the communication flow highercharacteristic. Through the Ethernet will buoy and shore station constitute a LAN, canrealize buoy and between station including data signal and the control signaltransmission. So as to realize the station to buoy the waters of the meteorological andhydrological, buoy state and if there is a tort target has real-time monitoring, in orderto take corresponding measures.This paper mainly study of Marine rights protection law enforcement buoy dataacquisition system, adopting ST company production based on ARM32-bit Cortex-M3of STM32F207as the controller chip, through the transplant embedded operatingsystem μC/OS-III management data signal acquisition, control command to send, datastorage, etc., through the transplant light TCP/IP protocol based on the embeddedEthernet to realize buoy and station communication.
