Design Of Embedded Data Processing System Based On Linux

With global land resources are increasingly tense and environment worsening of Marine resources, the growing importance of increasingly prominent, the development of human society inevitably more and more dependent on the ocean. While human only by acquiring the Marine environment change rule, on the basis of scientific, reasonable and economy to develop and utilize Marine.Therefore this topic to study a kind of economy and convenient to carry the disposable temperature salt deep probe survey data processing system. Used for collecting different area of different depth and Marine environment factors, all kinds of data, support the massive storage capacity and real-time data transmission. Through this method, detect data recovery to the ground and conveniently to collect data transmission on general-purpose computers, so as to make further data processing and analysis. Compared with the results of the original data display detection, after the backend fitting, processing is formed after the chart give people more intuitive impression.This topic need to choose reasonable realization ways, considering distributed control, flexible manufacturing, digital communication and information home appliances embedded system toward the high speed, high precision, low power dissipation direction. Hardware real-time ability the enhancement, and embedded system software scale also expands unceasingly, real-time multitasking operating system (RTOS) and with Linux platform based on embedded system design, become the mainstream of the embedded system.This topic selection embedded Linux realization means to realize data acquisition and storage, and LCD to display dynamic curves, using the rs-five 232 interface and the lower level computer connected to receive data.
