Software Design Of Water Conservancy Engineering Simulation System

Going along with the rapid development of science and technology, more and more requirements are put forward to the modernization of water conservancy system. At the present, our country takes great advantage of modern computer technique, communication network technique etc. to realize all kinds of digital water conservancy simulation system in the construction of huge water conservancy projects and huge irrigation projects. To fully give out these systems'function, it is particularly necessary to train the system operators. This paper hopes to do some positive exploration in the field of developing water conservancy simulation training software based on the practical engineering project.At first, this paper introduces the background, the domestic and overseas general situation and the intending trend of the project. Then through the analysis of simulation system, the main design contents of water conservancy simulation system are presented. According the characteristic of this simulation system, this paper further describes the simulation system's design principals, function traits, and the configuration of developing environment. Afterwards, single reservoir's mathematical model is built and then the water conservancy system's mathematical model is easily obtained. Using fourth order Runge-Kutta Method and Visual Basic 6.0 developing environment, the mathematical model is easily carried out. Subsequently, this paper simply describes the basic conception of Object-Oriented, the basic characteristic of Object-Oriented, the advantage of Object-Oriented method, the analysis and design means of Object-Oriented and the system's modeling design is carried out with Unified Modeling Language (UML). The user case diagram describes the water conservancy simulation system's requirement analysis; the active diagram describes the mutual relation of the system's dynamic model and makeup components; the class diagram defines the system's classes, shows the relation between the classes and presents the classes'internal structure.At last, this paper does some studies on the design problems of water conservancy simulation system. The design of the system's function modules such as account management and parameter configuration module, database design module, real time watch module, alarm module, historic data management module, dynamic display module, log management module and help function module are introduced and designed separately. The results show the simulation software can commendable simulate the practical water conservancy system's situation. The simulation interface is friendly and convenient, and functions of the simulation software are strong, so the simulation software has broad application prospect.
