Based On B/s Structure Of Long Distance Oil Pipeline Leak Detection Background Processing System

Nowadays, the price of the international crude oil is raising constantly. Therefore, the leak detecting of transporting-oil pipe is paying more and more attention by lots of countries. The thesis based on the requirement of national large oilfield, researching the implement and design of the real-time supervisory system of transporting-oil pipe based on B/S mode. An easy to deploy and scalable, low complexity of the development, low-cost and cross-platform, haleness and practical system of the leak detecting of transporting-oil pipe based on web technology was implemented, and the system was deployed and used in the oilfiled successfully, the running results show that the presented system achived the expected goals.Dynamic graph could show the change of the information to the users intuitively and understandably. The implement generally require the system has the ability to manage datas and communicate with the computer as C/S mode. Because of the disadvantage that long-playing wait and frequent renovation of classic model of web application, the implement of the dynamic web chart is difficult. Therefore, the implement of a low complexity of the development and the real-time supervisory system based on dynamic web chart is significant.This thesis analyzes the advantage and disadvantage of a great variety ofpopular technology in the question for discussion. And the difficult points of refresh in classic model of web application and drawing dynamic graph in real-time supervisory under B/S architecture are analyzed, and the solution of making use of AJAX and Dojo to realize the non—refresh page。local data refreshing and drawing graph on web page is put forward.
