Implementation And Design Of Intelligent Service System Of Environmental Information Based-on Agent

At present, the Computer Information Management System and Web site on the basis of each field or the department have already popularized in the Daqing oilfield. However, how to realize safely to join the correlation management system which used to issue relevant information with the web site effectively and automatically, and how to search accurate information that the users need from these websites is the urgent problems to be solved. In full consideration of the factors such as the information's security, high-efficiency, compatibility and expansibility, etc, the Oilfield Integrated Information Management and Search Model based on software Agent are designed.This model adopts the expanded 3-layer client/server architecture and divides the application server layers into two sub-layers containing management and application server layer and issue and intelligent search layer. In order to ensure the adaptability of the model and support of developing system and data source with different architecture, Agent's technology of the software have been adopted. On the basis of the development of petroleum environmental protection information collecting, disposing, issuing and retrieval system, Java language is adopted to realize this model.The data manipulation mode constructed on Agent technology and three tier system is used to the inquiry of the integrated information of environmental protection with the combination of Agent technology and three tier construction. User can transmit data-, update data> inquiry data conveniently without knowing the data's geographic location and data type, meanwhile, this mode shield user from dealing data directly, thereby reduce the difficulty in data processing.This paper is made up of six chapters. At first, I state the signification and necessity for developing this system and give a brief introduction of research background and the role and difficulty of this paper; With the comparison of two common used structures C/S and B/S, the system structure in this paper is introduced in chapter 2; 1 present in chapter 3 the whole design, mainly give the system a total planning, study and discuss its safety system; From chapter 4 to 6,1 discuss the analyzing designing and realization of each component which make up of the Oilfield Integrated Information Management and Search Model based on software AgentThrough using the integrated information of environmental protection to test the system, the inside management, outside issue and intelligent retrieval of the information all reach to the anticipated design object. This model has realized smooth and automatic join between information management and issue. The information retrieval has realized filter effectively and the whole efficiency of the system is relatively high.
