Intelligent irrigation control system based on farmland greenhouse liquid fertilizer

Abstract

The invention discloses an intelligent irrigation control system based on a farmland greenhouse liquid fertilizer. The intelligent irrigation control system comprises a buffer tank, a remote transmission pressure gauge, an air inlet control solenoid valve, a water pump, an irrigation water outlet, a stirring water inlet, a stirring water outlet, a water inlet solenoid valve, a stirring control solenoid valve, a siphon pressure regulating valve, an ejector, a flow sensor, a fertilizer A control solenoid valve, a fertilizer B control solenoid valve, a fertilizer C control solenoid valve, a fertilizer mixing barrel, a power distribution cabinet, an irrigation solenoid valve, a Y-type filter, a water inlet, a touch screen, a system starting button, a system stopping button, a main switch, an alternating current contactor, a frequency converter, a 12V switching power supply, a 5V switching power supply, a soil humidity acquisition system, a single chip microcomputer master control unit, aninternet of things system, a soil humidity sensor, a water level sensor, a temperature sensor, a humidity sensor, an illumination intensity sensor, a carbon dioxide sensor, a light compensating lamp,an air exchange fan and a relay module. A water and fertilizer integrated machine is controlled by the single chip microcomputer master control unit, the internet of things system and the soil humidity acquisition system to realize the automation of the whole process of fertilization and irrigation, manpower and material resources are reduced, water and fertilizer waste as well as water and soil pollution are avoided, and the irrigation efficiency and the utilization ratios of water and a fertilizer are increased.

Description

technical field [0001] The invention is an intelligent irrigation control system based on farmland greenhouse liquid fertilizer, which belongs to the field of mechatronics. Background technique [0002] my country is a large agricultural country. Irrigation and fertilization of crops requires a lot of water and human resources. In the process of irrigation and fertilization, excessive and unreasonable fertilization will lead to low water and fertilizer utilization and irrigation efficiency and even lead to soil and water pollution. Improve irrigation efficiency and water and fertilizer use efficiency to reduce waste of human resources, control large amounts of fertilizer loss and prevent soil and water pollution. Although there are a large number of water-saving irrigation technologies, it is difficult to automate the whole process of fertilization and irrigation, and the irrigation efficiency and water and fertilizer use efficiency have not been significantly improved. In...
