specific Embodiment
[0119] City S is a typical rainy city in the south, with a subtropical monsoon climate and annual precipitation reaching 2000 mm. Affected by typhoon weather in summer, city S is prone to extreme rainfall events such as heavy rainstorms, and urban waterlogging occurs frequently. The urban inland river pollution situation in City S is also not optimistic. The main stream and four tributaries of the urban inland river in S City are inferior to Grade V water quality, and the ammonia nitrogen and total phosphorus concentrations in the estuary during the rainy season exceed the Grade V standard for surface water. According to the analysis of pollutant sources, one of the important contributors to the pollution of urban inland rivers is the combined pollution overflow of the drainage pipe network. In view of the demand for urban waterlogging prevention and overflow pollution prevention and control, the drainage network of city S urgently needs to build an online model for intelligen...

An online analysis method for urban drainage network solves the problem of inflexible model calculation results and poor real-time guidance in the existing drainage network, and belongs to the interdisciplinary fields of municipal engineering, environmental engineering, management and computer science. The present invention includes: S1, constructing the hydrodynamic water quality calculation engine of the drainage pipe network; S2, using the hydrodynamic water quality calculation engine of the drainage pipe network to arrange the scene pipe network water quality and hydrodynamic operation tasks into multiple independent task units, according to the tasks of the task dispatching center Instructions and input data of the drainage pipe network, dynamically assign and schedule task units on the cluster distributed architecture, complete the scene simulation of the drainage pipe network, and obtain the calculation results of the hydrodynamic and water quality of the drainage pipe network; S3, according to the complex network theory, the drainage The pipe network is abstracted as a two-dimensional point-line directed weighted network, and the network topology and hydrodynamic water quality calculation results of the drainage pipe network are analyzed.
Description
technical field [0001] The invention relates to an online analysis method of urban drainage pipe network based on cluster distributed architecture and complex network theory, which belongs to the interdisciplinary fields of municipal engineering, environmental engineering, management and computer science. Background technique [0002] The rapid development of the Internet of Things, cloud computing, and big data has given birth to the concept of "smart city" and the rapid progress of the pilot work. As one of the important infrastructures of the city, the drainage pipe network system is a key link in the "smart" management of the city. The design standards of the urban drainage network system in the early stage were relatively low, and the degree of attention was poor, which led to problems such as chaotic management system and serious sedimentation and aging in the drainage network system. In addition, with the acceleration of urbanization, impermeable surfaces such as bui...
