Design And Implementation Of The Safety Assessment System For Electric Power

Design and Implementation of the Safety Assessment System for Electric PowerSafety assessment for electric power involved in all aspects of safety management, informative, and the information transmission is complicated. From the specific content of the assessment, it requires a strong technical perspective, but from the information transmission that is from the distribution point of view, it has maintained close contact with the power companies in every department. The Safety Assessment for Electric Power (SAS), build based on WEB-based technology, can take full advantage of existing network resources and units to carry out safety assessment work, which solves the security of information flow and management and improves working efficiency.With the fast development of the information technology, the computer technology has seeped through all profession in society. Electric power industry in China is one of the earlier areas of using computer in the production and management process. "95" initially explicitly puts forward the "three unified" principle and the data applications develop to the direction of sharing. Information working develops from independent each computer application systems to "integrated" and "integrated", and that information collection, processing and transmission is more rapid and smooth, shared in a higher degree.In order to prevent personal accidents, power grids, and major equipment accidents, safety assessment for electric power primarily is specific three aspects including electricity production equipment, labor safety and working environment that may lead to accidents, and uses risk assessment methods on the basis of electrical safety checking of the status and level of diagnostic assessment. The purpose of that is to grasp the basis of production safety situation, predict the existence and severity of risk factors, clearly anti-accident work, and need to take corrective measures to implement advance control, the ultimate goal of it is to reduce and eradicate accidents.Along with more and more developers taking J2EETM server as the first choice platform of server application, developer experience as well as obtains may the reusedesign be more and more important. Introducing the reasonable design pattern may help us to find the solution to the same or similar question; and the frame may enhance the development speed in the very big procedure and reduce the development cost.The Struts frame most is earlier than May,2000 which published as the Jakarta project constituent, the Jakarta project organizes the operation by the Apache fund. The project establishment hopes improve and enhance Java ServerPages, Servlet, the label store house as well as the object-oriented technical level. The Jakarta project has very many successful parts, for example product and so on Tomcat, Cactus as well as Log4. More over Struts opens the source code project, its prospect is limitless.In the developing of SAS, for the very good management, the processing service level and the model relations, increased the data lasting level between the service level and the model, the data lasting level realization had the many kinds of methods: Directly using the SQL/JDBC manual code to continue the level, the operation quite is simple, easy to operate, but the correlation big project says, when demand change must simultaneously change many SQL sentence, more over in the procedure connects the button-up operations also increased the extra risk which the database server collapses; Using the EJB already has become the long-enduring data the recommendation way recently, but CMP correspondence table granularity excessively thick, could not completely use the rich Java data type, was insufficient to many condition connections and the inquiry support, moreover, EJB only could put in the EJB vessel uses, very difficultly entrusted with heavy responsibility its code outside the vessel; The Hibernate frame is completely object-oriented relational model, in the performance history has removed very many tedious work, enables the development to be allowed to concentrate the business problem in the realization, no matter the development use starts from the territory model from the top application development strategy, or starts from the existing database pattern to use Hibernate and the suitable tool from the bottom upward development, all will be able to reduce the massive development time, will complete to the lasting level development also more and more many uses Hibernate frame.This article had not proposed the new design theory method and new technology, only on the foundation of developing a practical application, it studies the theory and the practical application will unify, effectively will solve the practical application. Basically the system has met user's needs and achieved the anticipated goal.
