FBG (Fiber Bragg Grating) is especially suitable for the shafting operation condition monitoring of rotating machinery under the harsh working environment for a long time with its advantages of anti-electromagnetic interference, easy reuse, good stability, environmental adaptability and so on. The overall architecture of the shafting operation condition monitoring system based on FBG sensing network is proposed. In the system, FBG multi-channel distributed sensing network is used to fully apperceive the real-time operation condition information of the equipment. While the Windows Presentation Foundation (WPF) and 3-Dimensional Studio Max (3DMAX) technologies are used to realize the intuitive 3-Dimensional (3D) virtual display to monitor the equipment. Besides, the sensing information data stream is processed in real time to display the running state of the equipment. Also, mass sensing information is analyzed and stored by the real-time processing method. The stability and reliability of the proposed framework and key technology is verified by the system long-time implementation results.

In this paper, discusses the design and realization of large file asynchronous upload and Broken-point continuingly-transferring based on ASP.NET MVC. At the first, brief review the traditional upload method based on HTTP(Hypertext transfer protocol) protocol and ASP.NET(C#), point out the existed malpractices, while introduce the basic principles of asynchronous upload and broken-point continuingly-transferring, and in-depth analysis of the design and realization of the function of asynchronous upload and broken-point continuingly-transferring in ASP.NET MVC.
