Design And Application Of The System Ship Data Acquisition And Analysis System

With the rapid development of modern electronic technology, the combination of the communication technology, the computer technology and the embedded technology are not only the main trend in nowadays, but also are developing and expanding greatly in many fields such as the industrial control, medical, electronic communication, navigation, aerospace and so on. This paper use communications technologies and embedded technologies are combined, The design of ship motion data collection, transmission and analysis of integrated system solutions is widely proposed. Under the supervision of this system, it could realize the subtotals, display and alarm functions of information of ship data, the drivers and crew of the ship can quickly access data in the ship, also considerables value at improving the level of the flight guarantee service.Based on the embedded Technology, serial communication and the short distance wireless communication theory, with AT91SAM7S64 being the central control unit, achieve the sink node to the design of system software and hardware. To achieve the design of the ship motion data acquisition system data communication, processing, and the corresponding protocol through the embedded software write the program. This subject comes from the project developed by Dalian Maritime University and Liaoning Province. It mainly introduces the domestic and abroad status at present, the significance and contents of this subject. Meanwhile, it studies the embedded OS, serial communication technologyand and the wireless transmission technology including the transplantation of OS, the error control, the serial communication technology and so on, The paper mainly finishes the work as follows:(1) According to the status of international ship motion date, comprehensive consideration of various factors, with the embedded technology as the core, build a data transmission receiver module and data processing module hardware platform.(2) Studying on the wireless communication protocol, using the embedded software programming technology, the wireless communication protocol is applied into operation and all functions of ship data systems communication network. (3) The ship motion data acquisition system is builded, respectively, hardware and machine network is debugging and testing, in this project,the test including the of two parts of unit testing and system integration testing.This system technology is advanced, stable running and practical. It has been successfully applied to a domestic ship models at present, it nor only gaines good results, takes the leading position in domestic, but also has widely development prospects.
