Pipe VT3 is 3DG6 type audion.
After energising, this multivibrator starts starting of oscillation, the initial electricity of the THRE pin of process chip U4 when being just initially powered up
Put down as low level, at this moment process chip U4 set, its OUT pin is high level, and electric capacity C8 starts to charge up；Electricity on electric capacity C8
Pressure is when reaching threshold level 2/3, and process chip U4 resets its OUT pin output low level, and electric capacity C8 starts to discharge；This multi resonant i.e.
Agitator can alternately export high level and low level.
Meanwhile, probe G1 and probe G2 is also measured to the humidity of soil, and provides certain measured value, this survey
Value exports to voltage comparator after the process of two-stage amplifying circuit, and voltage comparator then exports corresponding signal and touches to Schmidt
Send out device.When the humidity of soil is inadequate, the resistance between probe G1 and probe G2 is very big, and the measured value that it is given is more than potentiometer
Value set by R5, at this moment voltage comparator output high level.Resistance when soil moisture is enough, between probe G1 and probe G2
Value diminishes, and the measured value that it is given is less than the value set by potentiometer R5, at this moment voltage comparator output low level.
When multivibrator and voltage comparator all export high level, when as soil moisture is inadequate, NAND gate A4 is defeated
Go out high level, on-off circuit turns on, relay K obtains electric its normally opened contact closure, water pump starts to draw water, and time of pumping is by electric capacity C8
Charging interval determine, be set to 2 minutes in this example.Multivibrator upset after terminating the pumping for water pump time, electricity
Hold C8 to start slowly to discharge, multivibrator starts to export low level, and NAND gate A4 exports low electricity, and par pump stops pumping；Electricity
The time holding C8 electric discharge is the time that water pump stops pumping, and water pump stopped pumping the time for 30 minutes in the present embodiment,
When water pump stops pumping, water continues down to ooze, and the setting water pump time of stopping pumping is to prevent speed ratio seepage velocity of drawing water
Lead to that situations about watering occur more soon.After terminating the time of stopping pumping, after that is, electric capacity C8 electric discharge terminates, process chip U4 weight
New set, multivibrator exports high level again, and electric capacity C8 is again introduced into charged state；Probe G1 and probe G2 continues simultaneously
Monitoring soil moisture, such as soil moisture are not enough, and voltage comparator continues to output high level, and NAND gate A4 also exports high level, water
Pump draws water again；As soil moisture enough, voltage comparator then exports low level, even if at this moment harmonic oscillator output high level,
NAND gate A4 all exports low level, and water pump no longer works.Probe G1 and probe G2 can detect soil moisture always afterwards, works as soil
Then repeat the above steps when humidity is not enough again, such circulation then can be very good Fructus Fici is watered, will not be because watering
Speed is faster than seepage velocity and lead to the phenomenon pouring water excess, improve the present invention pouring effect.
As described above, the present invention just can be realized well.
