Description

technical field [0001] The invention relates to an artificial rainfall device, in particular to an intelligent outdoor artificial rainfall simulation device and an artificial rainfall simulation method, belonging to the technical fields of hydrology, environmental science and geology. Background technique [0002] Hydrological processes such as rainfall, runoff, and infiltration are accompanied by changes in the natural environment and material migration, such as water erosion by rainfall on soil, changing geological and landforms; rainfall infiltration and runoff drive the migration of nutrients, and pollutants enter surface water or infiltration Water pollution caused by groundwater; rainfall causes water redistribution, and different underlying surfaces have different water holding capacities, etc. These phenomena involve hydrology, environmental science, agriculture, and forestry, among which the hydrological process, the migration of pollutants, soil erosion, and water ...

AI Technical Summary

Problems solved by technology

[0006] 1. The accuracy of rain intensity is low. The whole simulated rainfall process can be regarded as a feedback adjustment process. The final control instrument issues rainfall instructions, including parameters such as rainfall intensity and rainfall duration. Under the influence of uncertain factors such as power supply capacity, the magnitude of the rain is a fuzzy number, fluctuating within a certain range, and from the current real-time experimental data, the interval is relatively large, and the experimenters can use the rain gauge feedback feedback Small adjustments are made, but it is generally difficult to accurately meet the experimental requirements;

[0007] 2. The current final control instrument is generally a control box, which is connected to the water pump and rain gauge at the same time. During the experimental work, instructions are issued and feedback data are received. As the brain of the experiment, the final control instrument has a low degree of automation, poor controllability, and relatively single instructions. , generally there are only three rain intensity settings of large, medium and small, and the cost is relatively high, and the protection requirements are also high, and a large cost is required for field experiments
