Remote control method of water quantity and water quality of paddy field for users

Abstract

The invention discloses a remote control method of water quantity and water quality of a paddy field for users, and relates to the field of environment monitoring, water saving irrigation and agricultural non-point source pollution control. The method comprises steps of the water level and water quality data of the paddy field is acquired through a water level and water quality information acquisition device of a paddy field monitoring cell, and transmitting the acquired data to a wireless digital transmission module; the wireless digital transmission module transmits the data to a data analysis module; the data analysis module receives and analysis the data, and generates control signals for a water charging valve and a water discharging valve; a valve controller controls the water charging valve and the water discharging valve according to the signals received by the data analysis module; and a mobile phone terminal receives the data sent by the data analysis module, thereby achieving real-time implementation of manual control. According to the invention, according to requirements of ecological environment water demands and water environment protection in the whole growth period of the paddy field, by analyzing the water level and water quality information of the paddy field acquired in real time, and properly controlling irrigation and water discharging in the field, multiple objectives of remote control, water saving irrigation and slowing down of running away of nitrogen and phosphorus in the paddy field to the greatest degree are achieved.

Description

technical field [0001] The invention relates to the fields of environmental monitoring, water-saving irrigation and agricultural non-point source pollution control, in particular to a user-oriented remote control method for paddy field water quantity and quality. [0002] This method is based on the ecological water demand and water environment protection goals of the whole growth period of regional paddy fields, and based on the analysis of real-time water level-water quality data in the field, remote real-time control of paddy field irrigation and drainage, to achieve water-saving irrigation and to minimize the loss of nitrogen and phosphorus in paddy fields. Background technique [0003] The loss of nitrogen and phosphorus in paddy fields is one of the important reasons for the eutrophication of nearby receiving water bodies. The rice growth process will go through different stages such as soaking field stage, turning green stage, tillering stage, jointing stage, heading ...

AI Technical Summary

Problems solved by technology

The common point of the above patents is that the irrigation and drainage control is mainly based on the field water volume or water level as the judgment basis, ignoring the water quality of the field surface water, which will easily lead to the loss of nitrogen and phosphorus in the high-concentration field surface water under the condition of meeting the water demand of the paddy field, and increase the non-point source of agriculture. Risk of pollution and eutrophication of receiving water bodies
