ABSTRACT
Stanza water irrigation-agriculture stanza water not only the potential but is very
big and benefit people of country.To have to consume water 80% or so agriculture to
use aqueous of reasonable usage and develop the biggest efficiency should say having
count for much meaning.Particularly for be placed in the greater half inside country of
drought, the half dry region, stanza water will be keep on the development needs to be
solved the most important problem.The single slice of machine programmable control
stanza water irrigation system, that system can carry on supervision to the degree of
humidity of different soil, and Be according to the request of farm crop to soil degree
of humidity carry on in good time and just the right amount infusing water.This
controller takes the AT89 C51 single slice of machine as core, from spread a feeling
machine, the signal handles electric circuit and output control electric circuit etc.
composing.Collect by carrying out a data, control signal output, pass to spread a
feeling machine an auto examination the soil humidity carry out an automatic irrigation
control.Hardware, the soil contains the diagraph adoption HIH3610 degree of
humidities of amount of water to spread a feeling machine;A|D convert the adoption
ADC0809 chips, 74 LS373 chip etc..
Single slice of machine control part adoption the AT89 C51 single slice of
machine is mainly spread a feeling machine by soil degree of humidity, the signal
handles electric circuit and outputs control electric circuit etc. to constitute, the
software choice edits collected materials a language plait distance.The single slice of
machine can spread soil degree of humidity, the feeling machine examines of the soil
degree of humidity imitates quantity to convert into a number quantity, and deliver to
control system examination whether should irrigate.The system's vivid is strong, the
cost is low, High reliability, at physically applied in foreground vast.
