Abstract
The utility model relates to the art of automatic irrigation control device, in particular to an automatic green irrigation control device. The utility model has the technical proposal that a soil humidity detecting probe PL, a pressure comparator integrated circuit IC1, a resistor R1, R2, R3, and R4 and an adjustable resistor R are connected to form a soil humidity detection circuit; a resistor R5, a composite audion BG and a start switch DJ are connected to form a switch implementation circuit; a DC power is connected with a switch K and then jointed into the circuit. The utility model with simple structure and convenient production is installed nearby flowers, trees and plants of household, offices and greenbelts for environmental protection, thus achieving soil humidity detection at any time. In irrigation, an electric pump (or an electromagnetic valve) is automatically started and controlled; after the soil humidity is up to the requirement, the electric pump will be automatically closed. The utility model achieves the automatic control of water saving and water use for plant growth.
Description
Technical field
The utility model relates to a kind of greening irrigation automaton of irrigating the automaton field.
Background technology
Along with the continuous development of urban greening and water-saving technology, sprinkling irrigation and drip irrigation economize equipment are also widely applied.But existing water saving equipment almost completely relies on the people to observe back hand-guided electric pump or gate valve waters, and discharges water with regard to causing easily when soil does not need to water like this, causes water resource waste; When soil lack of water (dry and cracked), can not in time water, cause the flowers and plants forest withered, influence the normal growth of plant.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, a kind of humidity of instant detection soil is provided and controls the greening irrigation automaton that electric pump (or electric control valve) starts automatically.
Its technical scheme is: soil moisture detector probe PL, voltage comparator IC 1, resistance R 1, R2, R3, R4 and adjustable resistance R connect to form the soil moisture testing circuit; Resistance R 5, compound transistor BG and starting switch DJ connect to form the switch executive circuit; Place in circuit after the dc source DC connection K switch.
Described dc source DC comprises a kind of or combination of the dc source after battery or the AC-DC conversion, at starting switch DJ two ends parallel diode D.
The utlity model has simple in structurely, easy to make, be installed near the flowers, plants and trees of environmental greening such as family, office, greenbelt, can play and detect soil moisture at any time, in the needs pouring, open control automatically and open electric pump (or magnetic valve); Soil moisture can be closed electric pump again after reaching requirement automatically.Realize the automatic control of water saving and assurance plant growing water.
Description of drawings
Accompanying drawing is the circuit theory diagrams of a kind of embodiment.PL is the soil moisture detector probe among the figure; DJ is the starting switch of D. C. pump; DC is an accumulator.
Embodiment:
Be further described with regard to its circuit structure and operation principle below in conjunction with accompanying drawing:
Soil moisture detector probe PL, voltage comparator IC 1 (concrete model ICL7611), resistance R 1, R2, R3, R4 and adjustable resistance R connect to form the soil moisture testing circuit; Resistance R 5, compound transistor BG and starting switch DJ connect to form the switch executive circuit; At starting switch DJ two ends parallel diode D, place in circuit provided power supply for circuit after dc source DC connected K switch.
Operation principle is: when soil moisture detector probe PL detects antecedent soil moisture, then the soil moisture testing circuit of being made up of soil moisture detector probe PL connection voltage comparator IC 1 (ICL7611) resistance R 1, R2, R3, R4, adjustable resistance R is exported high level, connect the on-off circuit conducting that compound transistor BG forms via resistance R 5, electric pump DJ gets electric work; Otherwise electric pump DJ quits work.
Directly use battery as dc source in the foregoing description, the starting switch DJ D. C. pump that directly links is fit to indoor place such as family or office and uses.For large stretch of greenbelt can be by control water supply electric pump or motor-operated control valve startup and close, realize the purpose of control pouring automatically, electric pump in this application process can use powerful interchange electric pump (or motor-operated control valve), the dc source of power supply after by AC-DC conversion provide power supply to circuit.
