Problems solved by technology

[0005] However, due to the high water content of water hyacinth, there is currently a lack of more accurate measurement methods for its salvage volume, and because a scientific, real-time online monitoring and early warning system has not been established, the water management department cannot use information technology to monitor the pollution equivalent of aquatic plants. Early warning and efficient scheduling of operating forces to clean up pollution in a timely manner

Embodiment Construction

[0018] The present invention will be further described below in conjunction with specific embodiment:

[0019] According to an embodiment of the present invention, an online monitoring and early warning method for aquatic plants is provided, which mainly includes the following steps:

[0020] Step 1: When aquatic plants pass through the preset monitoring area, the radar monitoring system deployed in the monitoring area uses the principle of the difference in microwave echo intensity between floating objects and water surfaces to detect and locate reflective objects. Radar The electromagnetic energy is radiated by the antenna, and the electromagnetic wave reflected by the target is intercepted by the radar, and the distance, speed, area and orientation of the target are detected after processing. The radar obtains the target trajectory by measuring the position of the moving target, so as to determine the direction of the target's movement and predict the future position.

Abstract

The invention discloses an online monitoring early-warning method for aquatic plants. The method mainly comprises the following steps: when aquatic plants pass through a preset monitoring area, acquiring types, an area and a movement speed of the aquatic plants passing through a monitoring cross section through a method combining a radar and a video, measuring and calculating a pollution equivalent of the aquatic plants, predicting a movement trend of the aquatic plants in combination with an aquatic plant drifting model, and pre-warning a downstream water management department in time. The online monitoring early-warning method for the aquatic plants, disclosed by the invention, can solve the difficult problems that the pollution equivalent of the aquatic plants cannot be quantized, online monitoring and warning cannot be achieved in real time around the clock, and the like.

Description

technical field [0001] The invention relates to the technical fields of water resources and water environment, in particular to an online monitoring and early warning method for aquatic plants. Background technique [0002] Due to the eutrophication of the water body and the suitable living environment, aquatic plants such as water hyacinth and duckweed have grown and spread seasonally in some rivers, lakes and reservoirs in southern my country in recent years, seriously affecting aquaculture, shipping, hydropower, water plant water intake, The water surface environment and water quality, etc., the areas affected by it vigorously carry out salvage work, which cannot solve long-term problems. Among them, water hyacinth has been flooded in 17 provinces and autonomous regions in southern my country, and is one of the most serious perennial aquatic weeds in the world. [0003] According to statistics, in the early 1990s, Kunming's Daguan River and Dianchi Lake's water hyacinth g...
