Abstract

The invention discloses an SWMM model real-time dynamic interaction method and system in a Web environment, and the method comprises the steps: abstracting an information model of an SWMM model service from the two perspectives of attributes and behaviors based on an object-oriented method; real-time data input and output of the SWMM model are realized by calling an external interface; designing a description document of an SWMM model service based on a description method of an OGC WPS processing service and an extensible markup language; expanding an OGC WPS interface specification, and designing an SWMM model service interface; and designing a real-time dynamic interaction process of the SWMM model service in the Web environment, and using the SWMM model service according to the interaction process. Based on the HTTP network protocol, sharing and service of the SWMM model are achieved in the Web environment, near-real-time access of observation data is supported, and the method has the advantages of being cross-platform, flexible to use and the like.

Description

Technical field [0001] The invention belongs to the interdisciplinary field of geographical information science, computer network, hydrology and other disciplines, and is a real-time dynamic interaction method and system for SWMM (Storm Water Management Model) model in a Web environment. Background technique [0002] The stormwater flood management model SWMM was developed by the U.S. Environmental Protection Agency (EPA). It is a precipitation-runoff simulation model. It is mainly used to simulate the impact of single or continuous precipitation events on water quantity and quality in cities or watersheds. It has been widely used in cities. Infrastructure planning, urban flooding simulation, etc. EPA provides an open source and free desktop running software for Windows systems, EPA-SWMM. Its input is a project file INP, which contains the structural information of the drainage pipe network in the study area (such as pipes, drainage outlets, nodes, etc.), rain gauges (rain g...
