The Research And Development Of Ocean And Maritime Information Data Acquisition Device Based On The Broadband Satellite

Since the 18th CPC National Congress the Marine power strategy has been put forward asone of the major national strategy. Ocean development has been drawn more and more attention.To makes the Chinese dream of Marine power come true, the Oceanography should be fully understood. The Ocean and maritime information data acquisition, as one of the most important methods to study Oceanography, is to make full use of various kinds of sensors, switch the non-electricity signal about the ocean maritime into analog signal, then converts analog signals into digital signals to store, calculate and transmit the data. The Ocean maritime information data acquisition is the inevitable outcome of the developing of computer technology used in the Oceanography. The research of Ocean maritime information data acquisition device makessignificant contribution to marine resources development, marine environmental protection, marine disaster prevention, maritime rights ,interests maintenance and maritime traffic safety.The field of ocean maritime (such as island) has its own environment, neither the wirednetwork is available nor the wireless base station can be used in this environment. So, thesatellite is the only tool can be used to maintain communication with the land. Broadbandsatellite communication system can provide convenient, efficient, safe, high quality satellite datacommunication in this unique environment, which improve and strengthen the Marineinformation data collection greatly.This article will analysis the demand of maritime information data collection and design the function of ocean maritime information data acquisition device, and design the devices of the marine satellite communications, the maritime information data acquisition and power supply at first. Then show the whole progress of the ocean maritime information data acquisition client with PLC and meteorological hydrological data acquisition from sensors, video data acquisition from computers and video cameras and data transferring in an island as a example. At last, the issue will introduce the implementation of functions such as ocean maritime information data acquisition and server control, file management, data display, video monitoring. Accomplish the whole progress of maritime information data acquisition based on the broadband satellite.In this issue, the progress of remote ocean maritime information data acquisition is implemented by using the ocean maritime information data acquisition which combines equipments such as PLC and computer and the broadband satellite communication system.Which is Forming a set of scientific method of real-time ocean maritime information data acquisition Providing accurate real-time data to support Chinese ocean development. Which hascertain significance to promote the development of Marine economy in our country.
