Farmland non point source pollution surface runoff irrigation amount monitoring device and method

Abstract

The invention provides a farmland non point source pollution surface runoff irrigation amount monitoring device and method; the monitoring device comprises the following elements: water volume sensors arranged on irrigation water pipe outlets of each surface runoff monitoring district irrigation water port and used for obtaining irrigation amount data driving surface runoff generation in each surface runoff monitoring district, and the obtained irrigation amount data is sent to a wireless measurement and control module; the wireless measurement and control module used for receiving the irrigation amount data sent by the water volume sensors, and sending the received irrigation amount data to a remote reception module; the remote reception module used for receiving the irrigation amount data driving surface runoff generation and sent by the wireless measurement and control module. The farmland non point source pollution surface runoff irrigation amount monitoring device and method can automatically monitor the irrigation amount driving the surface runoff generation, the runoff monitoring data can be remotely transmitted, and a monitoring result is more accurate.

Description

technical field [0001] The invention relates to the technical field of farmland non-point source pollution monitoring, in particular to a device and method for monitoring the amount of farmland non-point source polluted surface runoff irrigation. Background technique [0002] At present, the loss of farmland nutrients into the environment has caused many problems such as eutrophication of surface water, excessive nitrate in groundwater, reduction of farmland production capacity, and decline of ecological environment quality. It is imperative to protect the water quality of water bodies and reduce the migration of farmland pollutants to water bodies. Only by monitoring farmland non-point source pollution and clarifying its occurrence process and development characteristics under different conditions can we formulate targeted non-point source pollution prevention and control strategies . At present, the devices and methods generally used for surface runoff monitoring of farml...

AI Technical Summary

Problems solved by technology

[0005] In view of this, how to overcome the current problems such as the inability to monitor the amount of surface runoff irrigation from non-point source pollution in farmland in real time and the large error of monitoring results has become a technical problem that needs to be solved at present.
