Sudden drainage basin water pollution accident monitoring method and device

Abstract

The invention provides a sudden drainage basin water pollution accident monitoring method and device. The method comprises the following steps: acquiring hydrological data of a monitoring area; and inputting the basic drainage basin data into a preset water quality analysis model, and outputting water quality data in a prediction time period, wherein the preset water quality analysis model is constructed based on 3DCNNs and is obtained by taking output data of the water flow numerical simulation model as a label and taking corresponding basic drainage basin data as a sample for training. The method solves the problem that simulation models such as MIKE 21 and the like are too long in calculation time, realizes rapid prediction of the basin water quality environment, effectively analyzes the future change trend and reduces time loss, so that the response speed of a local environmental department can be improved, and finally, basin water pollution accidents are rapidly, effectively and accurately treated. Besides, the method utilizes the time sequence attribute of 3DCNNs to analyze the change of the water quality data in time, and meanwhile, a residual network unit is added to analyze the change of the water quality data in spatial characteristics.

Description

technical field [0001] The invention relates to the technical field of computer graphics, in particular to a method and device for monitoring sudden river basin water pollution accidents. Background technique [0002] In recent years, major emergencies of water pollution in the basin have emerged one after another, and the ecological environment is facing serious threats. The relevant environmental departments have adopted real-time monitoring programs for water pollution accidents, and most of them use wireless sensor network systems to automatically monitor water quality indicators in the basin, such as ammonia nitrogen, five-day Biochemical Oxygen Demand (BOD 5 ), dissolved oxygen (DO) and other values, which are packaged and transmitted back to the cloud. Since the water quality data monitored by the sensor system has a small particle size and high cost, it cannot reflect the real-time changes in the water quality in the basin. Therefore, MIKE 21, SWAT and other water f...

AI Technical Summary

Problems solved by technology

These models are widely used in many aspects such as the water balance of the basin, the prediction of river flow, and the evaluation of non-point source pollution control. They are powerful, but the calculation time is long, and professional operation is required.

[0003] Specifically, the existing numerical simulation models of water flow such as MIKE 21 are powerful and time-consuming, and cannot quickly analyze the future trend of water quality when an emergency situation of water pollution occurs
