Design And Implementation Of The Network Real-time Time-series Data Acquisition System

With the economic and technological development, the popularity of the Internet and the development of the information highway, in every corner of society, there are a large number of real-time data. Some real-time data is closely related to people's lives, such as stocks, foreign exchange and so on. Although these data can be observed in real time through the website, but the data itself cannot be acquired. In this paper, Design and Implementation of the Network Real-time Data Gathering System is designed for the problem.For the poor performance of the current Network Data Gathering System, the author has made a detailed requirements analysis of the systems, and in-depth study of the way of the site data analysis and extraction. And on this basis, the real-time time-series data acquisition system is designed and implemented. The paper solved the difficulty of getting the changing number of pages. Finally, the author has fulfilled URL generated automatically, user's data location, rapid collection of Web data, data query and curves generated and other important functions.The focus of the procedure is to establish common rules of data analysis, It can get dynamic data of a majority of sites. Use the multi-threaded technology to resolve the problem that system does not respond while the source code is being downloaded, establish the profile to solve the problem of re-instated when restart the system. Procedures set character encoding is "utf8". System interface is simple and easy to use. Because of the establishment of the menu bar, there is only one button on the entire interface, all settings to achieve through the pop-up menu.Program is a Qt's C++ project in the Linux system, is the author's first attempt on Linux System. System has passed the test, with more efficient, more stable work, the applicability of a stronger.
