Irrigation measurement and control apparatus, system and method

Abstract

The invention relates to an irrigation measurement and control apparatus, system and method and to the field of agricultural irrigation, and mainly aims at increasing water resource utilization rate in soil irrigation. A mainly-used technical scheme is that the irrigation measurement and control apparatus comprises an electric valve, a first sensor, a second sensor, a control unit, and a relay; the electric valve is equipped with a water inlet and a water outlet; the first sensor is arranged on the water inlet end of the electric valve and is used for acquiring water inflow of the water inlet end; the second sensor is used for acquiring the water content of the soil; the control unit is connected with the first sensor and the second sensor and is used for determining whether the electric valve is required to be opened or closed by using a preset determining rule and generating a corresponding control signal according to received water inflow information and the water content information of the soil; and the relay is connected with the control unit and the electric valve and is used for receiving the control signal and controlling the electric valve to be opened or closed in response to the control signal.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to an irrigation measurement and control device, an irrigation measurement and control system and an irrigation measurement and control method. Background technique [0002] Agricultural irrigation mainly refers to the irrigation of agricultural farming areas. my country is a large agricultural country, and agricultural irrigation requires a lot of water, and agricultural water consumption accounts for more than 70% of the total social water consumption. In recent years, the shortage of water resources in my country has become increasingly serious. Therefore, water-saving agriculture will become an important part of the development of modern agriculture in our country. direction. The water demand of crops is different at different times. Understanding soil moisture and rational irrigation will help to improve crop yield. Irrigation according to the water demand of c...

Problems solved by technology

However, although the agricultural water-saving technology of automatic irrigation in my country has developed to a certain extent at present, and the phenomenon of extensive flooding has been basically controlled, most of them are timing irrigation technologies, which will be irrigated on time regardless of whether the soil is dry or not. Resource utilization rate is still very low, resulting in waste of water resources
