Embodiment
As shown in Figure 1, a kind of automatic control photovoltaic water-saving irrigation system of the utility model, comprise irrigation rig, for the photovoltaic module that irrigation rig is provided power supply with for the humidity control module that irrigation rig is controlled automatically, described humidity control module comprises power supply 12V, humidity sensor display E3, relay J and comparison circuit, the end of described humidity sensor display E3 connects power supply 12V, the other end connects the input of comparison circuit, the output of comparison circuit is connected power supply 12V by the relay J coil, the output of described photovoltaic module connects irrigation rig by the normally opened contact J1 of relay J, the two ends of the normally opened contact J1 of described relay J are parallel with the anti-surge circuit that resistance R 5 and capacitor C are formed, and this module is excessive and burn out relay contact switch J1 in order to prevent that motor circuit from connecting the moment surge current.
Described irrigation rig comprises non-brush permanent-magnet DC motor M, water pump and water pipe, and described permanent-magnetic brush-less DC motor M drives water pump and carries out irrigation operation by water pipe.
Described photovoltaic module comprises solar components 1 and controller for solar 3, and the output of described solar components 1 connects the input of controller for solar 3.Can carry out series and parallel to described a plurality of solar components 1 according to the model demand of used non-brush permanent-magnet DC motor M and connect, to satisfy demands such as used non-brush permanent-magnet DC motor M rated voltage and rated power.
Comparison circuit described in the utility model is made up of humidity sensor display E3 resistance, resistance R 1, adjustable resistance R4 and resistance R 2, the 12V power supply is after resistance R 2 and adjustable resistance R4 dividing potential drop, insert the inverting input of comparator 2, humidity sensor display E3 and R1 form divider, one end connects power supply 12V, and the other end connects the in-phase input end of comparator 2, simultaneously resistance R 1, R4 ground connection, the coil two ends of relay J are parallel with bypass diode D1, anti-current loop.
Change threshold value humidity H
THVery convenient, as long as correspondingly change comparator threshold voltage V
TH(be V
Instead) value get final product.V
THValue increases, H
THIncrease; Vice versa, adjusts very convenient.As long as RH determines that the humidity characteristic of RH determines that then R1, R2, R4 can conveniently obtain.
During operate as normal, humidity sensor display E3 monitors the soil moisture value in real time, when humidity value is higher than setting value, the resistance value of humidity sensor display E3 descends, comparator output high level, and this moment, the coil both end voltage value of relay J equated, the coil no power of relay J, relay normally open contact J1 opens, the motor M no power, and expression need not to irrigate.When the detected soil moisture value of humidity sensor display E3 is lower than setting value, the output output low level of comparator 2, this moment relay J coil two ends bad student's voltage difference, it is electric to be that the coil of relay J gets, the contact switch J1 adhesive of relay, and the motor M energising starts, drive water pump and draw water this moment, irrigate by water pipe, reach setting value up to humidity sensor display E3 detected value, system stops to irrigate.This has just realized round-the-clock unmanned automatic irrigation, has saved manpower greatly, and owing to adopt the photovoltaic module energy supply, makes more energy-conservation, the efficient of package unit.
