The system comprises a water layer management unit, as well as a meteorological acquisition unit, a water layer precision control unit and a soil environment acquisition unit which are connected with the water layer management unit through wireless bridge communication, wherein the water layer management unit comprises an industrial control computer and a main node network bridge; the meteorological acquisition unit is composed of a branch node network bridge I, a rainfall controller, an evaporation volume sensor, an atmospheric temperature sensor, and an anemorumbometer; the water layer precision control unit is composed of a branch node network bridge II, a water layer controller, a touch screen, a water level sensor, a flow meter, a water injection valve and a water discharge valve; and the soil environment acquisition unit comprises a branch node network bridge III, a multi-channel analog collector, water temperature sensor, a soil temperature sensor, a soil water content sensor, and a soil thermal flux sensor. The system has high automatic degree, and is reliable in water layer precision control.

Description

technical field [0001] The invention belongs to the automatic control technology of agricultural engineering, and mainly relates to a precision control system of rice paddy water layer. Background technique [0002] In the past rice planting and management process, field operations such as irrigation were controlled entirely by the grower's years of planting experience. Due to natural conditions, human error, and different water requirements during the rice growth period, excessive water use and excessive water shortage were prone to occur. Phenomena, it is impossible to quickly and accurately implement precise water layer control based on crop water demand information to improve water utilization and water production efficiency. At the same time, it also consumes a lot of manpower and material resources, and cannot ensure the real-time requirements of the entire growth period of rice. Contents of the invention [0003] The purpose of the present invention is to solve the ...
