【摘要】：我国水利数学模型的理论和算法与国际水平相比总体已处于先进水平,有些方面甚至已经处于领先水平。然而,一直以来水利行业都采用“自行开发、自行使用”的方式,其中尤以水利数值计算模型软件有关方面为甚,这种方式使得与模型有关的软件开发长期处于滞后状态,水利仿真计算系统软件开发周期较长且可重用率低,严重阻碍了优秀模型的推广使用及我国水利仿真计算事业的发展。本文针对以上问题,提出了以模型标准化为基础,以模型库为核心,以系统快速生成为特色,以确保模型开发者的知识产权为前提,基于云服务的水利仿真计算系统生成平台,并就该平台接口进行研究。本文首先针对我国水利行业尤其是仿真计算行业的现状及存在的问题,分别从业务层面和技术层面进行需求分析。在此基础上,对基于云服务的水利仿真计算系统生成平台及其接口的设计进行了介绍。一方面,平台以云服务的三层体系结构为基础,实现了用户与模型介质的有效隔离,为模型开发者的知识产权提供有效保障;另一方面,参照OpenMI标准,结合我国水利行业的特性,通过对模型计算接口、模型组合计算接口、数据标准及输入输出接口的研究与设计,建立模型标准分类体系,实现多模型时间步级的数据交互及耦合计算,同时结合组件化技术,将所有数值计算模型设计实现成组件,同时利用平台系统生成框架快速生成多模型组合的水利仿真计算系统,使模型产品在使用过程中可以互相替换,并与具体业务系统完全独立,彻底解决重复开发问题。最后,通过平台的部署及实现,对接口研究工作的有效性及可实施性进行验证。通过对平台及平台接口研究工作,将从有助于改变我国水利专业软件开发中存在的低水平重复开发、难以维护更新的现状,促进我国自主知识产权成套水利专业软件的快速开发,提高水利行业的软件开发效率及水平,促进优秀模型的推广及使用。
[Abstract]:Compared with the international level, the theory and algorithm of the mathematical model of water conservancy in our country have been in the advanced level, and some aspects have even been in the leading level. However, the water conservancy industry has been using the "self-development, self-use" approach, especially in the hydraulic numerical model software, which has made the development of model-related software lag for a long time. The software development period of water conservancy simulation calculation system is long and the reuse rate is low, which seriously hinders the application of excellent models and the development of water conservancy simulation and calculation in China. Aiming at the above problems, this paper puts forward a water conservancy simulation computing system generation platform based on cloud service based on model standardization, model base as the core, system rapid generation as the characteristic, and ensuring the intellectual property of model developer as the premise. The interface of the platform is also studied. In this paper, first of all, according to the current situation and existing problems of water conservancy industry, especially the simulation calculation industry, the requirement analysis is carried out from the business level and the technical level respectively. On this basis, the generation platform and interface design of water conservancy simulation computing system based on cloud service are introduced. On the one hand, based on the three-tier architecture of cloud services, the platform realizes the effective isolation between users and model media, and provides effective protection for the intellectual property rights of model developers. On the other hand, according to the OpenMI standard, combined with the characteristics of water conservancy industry in China, through the research and design of model calculation interface, model combination calculation interface, data standard and input and output interface, the model standard classification system is established. The data interaction and coupling calculation of multi-model time step level are realized. At the same time, all numerical calculation models are designed and realized as components, combined with component-based technology. At the same time, the platform system is used to generate the multi-model combination water resources simulation calculation system quickly, so that the model products can be replaced each other in the process of using, and completely independent from the specific business system, so that the problem of repeated development can be solved thoroughly. Finally, through the deployment and implementation of the platform, the effectiveness and implementability of the interface research work are verified. Through the research work of platform and platform interface, it will be helpful to change the low level repeated development in the development of water conservancy professional software in our country, and it will be difficult to maintain the status quo of updating. To promote the rapid development of complete sets of water conservancy professional software in China's independent intellectual property rights, to improve the efficiency and level of software development in the water conservancy industry, and to promote the popularization and use of excellent models.
