Description

technical field [0001] The present invention relates to the field of water quality information processing, in particular to an application method, device, system and medium of an EFDC model based on cloud computing, and in particular to an application method, device, system and medium of an EFDC model based on cloud computing for water quality monitoring. medium. Background technique [0002] At present, many spatial mechanism models of water environment have been applied to simulate water environment, such as one-dimensional S-P model and QUASAR model, two-dimensional WASP model, three-dimensional EFDC model, MIKE series models, etc. Among them, the EFDC model has been paid more and more attention because of its comprehensive functions, which can simulate hydrodynamic force, water quality diffusion and poisonous substance diffusion. The EFDC model is mainly used to simulate and restore the hydrodynamic and diffusion scenarios of the target watershed, predict the water qual...

[0003] Prior art CN108256249A (Liu Xiao et al.) proposed an integration method for EFDC models in the Three Gorges Reservoir Area, which provides external functional interface services, but there are still many defects: (1) The user interface experience is poor, and the display area cannot be flexibly displayed or changed ;(2) The user needs to input specified parameters, which has high requirements for the user, and requires the user to be familiar with the data format of various interfaces, so that the input data meets the format requirements. If a certain input parameter is unreasonable, the model will crash; (3) For the hardware The requirements are high. Ordinary computers can only support one set of input data and the calculation speed of the model is slow. It is impossible to simulate and calculate multiple sets of input data at the same time, and it is impossible to compare the calculation results of multiple sets of input data at the same time; (4) The output result is single
