通过分析目前水文模型本地服务模式的不足,针对当前国内外Web Service技术在水文信息系统中的应用现状,设计并实现了一个基于Web Service技术的在线水文模型服务系统,示范了基于Web Service技术的网络数据获取、水文模型运行模拟等过程,说明基于Web Service技术的在线水文模型服务较好地实现了水文模型网络共享,支持异地模型访问。建议在线水文模型服务结构从网络数据库/数据中心获取数据,一定程度上解决了传统模式从本机上传海量数据等问题。这种在线水文模型服务模式节约了模型运行成本、降低了用户要求,在具体水文水资源管理事务中具有较好的应用和拓展前景。
By analyzing the current shortage of local hydrological service model and aiming at the current application of Web Service technology in hydrological information system at home and abroad, an online hydrological model service system based on Web Service technology is designed and implemented. Network data acquisition and operation simulation of hydrological model. It shows that the on-line hydrological model service based on Web Service technology can realize the network sharing of hydrological model and support remote model access. It is recommended that the on-line hydrological model service structure obtain data from the network database / data center and to a certain extent solve the problems of the traditional mode of uploading massive data from the local machine. This online hydrological model service model saves the operating costs of the model, reduces the user requirements, and has better application and development prospects in specific hydropower and water resources management issues.
