Accompanying drawing explanation
Fig. 1 is circuit diagram of the present utility model.
Embodiment
Fig. 1 is circuit diagram of the present utility model.As shown in Figure 1, the utility model comprises power circuit, testing circuit and control circuit.
Power circuit comprises transformer T, rectification circuit VD and pressurizer IC.The primary side of transformer T connects power input, and the secondary end of transformer T connects the input of rectification circuit VD, and the output of rectification circuit VD connects pressurizer IC.In the present embodiment, pressurizer IC is three terminal regulator, and rectification circuit VD is bridge rectifier.
Testing circuit comprises detection port A, detection port B, variable resistance R2 and triode Q1.The collector electrode of the output connecting triode Q1 of pressurizer IC and base stage.The base stage of detection port A connecting triode Q1, detection port B connects the first end of variable resistance R2, the base stage of the second end connecting triode Q1 of variable resistance R2.
As shown in Figure 1, in testing circuit, for ensureing that triode Q1 normally works, also comprise multiple auxiliary resistance.Resistance R1 and resistance R3 connects, and one end connects the output of pressurizer IC, and the base stage of other end connecting triode Q1, detection port A and variable resistance R2 is connected to the common port of resistance R1 and resistance R3.The base stage of resistance R4 one end connecting triode Q1, other end ground connection.Resistance R5 one end connects the output of pressurizer IC, the collector electrode of other end connecting triode Q1.The emitter of resistance R6 one end connecting triode Q1, other end ground connection.The collector electrode of resistance R7 one end connecting triode Q1, other end ground connection.
Control circuit comprises triode Q2 and relay J.The two ends of the magnet exciting coil of relay J connect the output of pressurizer IC and the collector electrode of triode Q2 respectively.Relay J also comprises contact J11 and contact J12, and contact J11 and contact J12 is connected between motor M and power input.Contact J11 and contact J12 closes, and motor M just switches on power, and can run.
Operation principle of the present utility model is as follows:
First the resistance of soil becomes the relation of negative correlation with the water content in soil.Water content in soil is higher, and the resistance of soil is less.
1, after switching on power, if water content reduces in soil, then the resistance value of soil raises, detection port A and detection port B port, and detection port A is high potential, triode Q1 and triode Q2 conducting, the magnet exciting coil adhesive of relay J, contact J11 and contact J12 connects, and motor M operates, namely irrigation rig starts to water, and irrigates plant.
2, after the water content in soil increases, the resistance of soil itself reduces, loop is produced between the direct voltage that pressurizer IC exports and the resistance of ground connection, the voltage of detection port A is reduced, then triode Q1 and triode Q2 all ends, the magnet exciting coil release of relay J, contact J11 and contact J12 port, motor M end is opened, and irrigation rig also quits work.
3 until moisture in soil along with the factors such as evaporation, plant absorption again reduce time, the utility model repeats the first step, motor M is worked irrigation again, so circulates.
