（2）Control unit power key is opened, opens air pump switch 43, water pot hydraulic pressure processed is set into parameter setting interface Power, speed of applying fertilizer, water tank water-storage pressure, pressure controller regulation and control bound, dissolved oxygen content or cyclic aeration time, water processed The parameter such as total amount, water tank irrigation level, water temperature, wherein water tank irrigation level refer to when reaching this water level, in automatic mode or Reservation protocol lower water tank water solenoid valve is opened, automatically into irrigation.
When the air pressure in water pot processed is higher than set pressure safety valve limit value, pressure safety valve loses heart straight automatically Reach set limit value to pressure, when the air pressure in water pot processed is less than set pressure value, pass through pressure regulator 26 Supercharging is realized, until pressure reaches set limit value, Stress control is similar with water pot Stress control processed in water tank.
（3）Click on automatic mode after the completion of parameter setting, device will be automatically into-water-water guide-water storage-irrigation processed of intaking Etc. process；There is water and the water level to be higher than water level in water pot processed when if installation's power source is opened in water pot, filled after clicking on automatic mode Putting will omit into water process, be directly entered water process processed, if having water and water level is less than water processed in water pot when installation's power source is opened In tank during water level, device will start water process processed after water inlet to water pot high water level processed after clicking on automatic mode, after water production is set, When device last time water water level processed has just reached design water production less than water level in water pot processed, device can force water inlet into Water level.
（4）Reservation protocol can set device to start the time on the basis of automatic mode, and reaching scheduled time device will be certainly Row starts.
（5）The present apparatus can check the information such as conventional water production, irrigation volume, dose, irrigation time by history report.
（6）According to manual mode, device completes to intake-and the process such as water-water guide-water storage-irrigation processed needs regulation manually The keying of valve, it is substantially carried out operating as follows：
A. unlatching water pot entering water electromagnetic valve 5 processed, pressure regulator compression relief cock 44, are at into water state；When in water pot processed When water level is less than middle water level, water pot floating ball lever meter 17 processed sends instruction water pot entering water electromagnetic valve 5 and opened, and starts to water pot processed 12 are supplied water, while Development of Venturi Fertilizer Applicator 9 is started working, during water inlet, water pot entering water electromagnetic valve 5 processed, pressure regulator pressure release Switch 44 always on, choose whether to open Development of Venturi Fertilizer Applicator 9 according to being actually needed, if desired, open Development of Venturi Fertilizer Applicator 9 Liquid manure mixed liquor is entered in water pot 12 processed afterwards, and when water level rises to high water level in water pot processed, water inlet process is completed.
B. water pot entering water electromagnetic valve 5 and pressure regulator compression relief cock 44 processed, Opening pressure regulation are closed after the completion of intaking Device supercharging switch 45, when the pressure of water pot 12 processed reaches limit value, the stable pressure of water pot 12 processed of pressure regulator 26, water process processed In, self-suction circulation pump 20 starts, and the current in water pot processed enter circulating water line, and venturi aeration is parallel with circulating water line Device 19, venturi aerator 19 are connected with pressure regulator 26, and liquid manure fluid-mixing is carried out through venturi aerator 19 First time aeration, institute's aeration body all come from and in water pot 12 processed, then by self-suction circulation pump 20, liquid manure fluid-mixing flows into static Blender 21, second of aeration is carried out, liquid manure fluid-mixing is flowed into water filling 12 processed by being aerated gas-liquid release 13 afterwards.This During come from water pot 12 processed due to the oxygen dissolved in circulation line, cause the atmospheric pressure of water pot 12 processed to reduce, pressure Air is pressed into water pot 12 processed by adjuster 26, steady pressure, constantly repeats this process.In the process dissolved oxygen controller- Temperature transmitter 15 can detect the current that self-circulating water pipeline is flowed into water pot 12 processed in real time, until current dissolved oxygen in water pot 12 processed Value reaches preset value, and water processed is completed.
C. water process processed is completed, into water guide process.Opening pressure adjuster increase switch 45 adds into water pot 12 processed Pressure, the water guide magnetic valve 23 on tank line road processed is opened, now water pot 12 processed has pressure differential with water tank 28, passes through pressure Power difference enters the hydraulic pressure in water pot 12 processed in water tank 28, when the water level of water pot 12 processed reaches below low water level, tank line processed Water guide magnetic valve 23 on road is closed, and completes a water guide process.Because water guide causes pressure oscillation in water tank 28, water guide mistake Pressure reaches preset value in the regulation of water tank pressure transmitter 33 water tank 28 after the completion of journey.
D. under manual mode, except needing to adjust above-mentioned valve opening and closing manually, also settable temperature of irrigation water, duty, filling Irrigate the time, and according to water pot dissolved oxygen value changes processed during cyclic aeration, set certain aeration time, or necessarily irrigate water-soluble Oxygen threshold value is solved, realizes the irrigation of different soils, Different Crop.
The present invention the heating integrated intelligent drip-irrigation control device of liquid manure gas and control method compared with the prior art have with Lower advantage：
1st, the present apparatus sets up automatic mode and reservation protocol, presets relevant parameter device by automatic running, reduces artificial Cost, automaticity are high；
2nd, in water pot processed part forced air by venturi aerator and static mixer in the form of microbubble and liquid manure The uniform blending of fluid, substantially reduces aeration time, avoids aqueous vapor lamination；
3rd, the present apparatus is due to the presence of water tank, and water processed can be achieved, irrigate while carry out, the saving time；
4th, device detects the dissolved oxygen content of liquid manure fluid in water pot processed by dissolved oxygen controller, can be according to specific crop and difference Growth period regulates and controls oxygen dissolving value；
5th, the present apparatus can obtain the time operated in the past and water production, dose, water temperature, irrigation volume by query history form Etc. information, it is easy to data to export；
6th, because water tank delivery port is connected with underground drip irrigation pipeline, water-saving fertilizer-saving, pollution is reduced.
Above-described is only the preferred embodiment of the present invention, it is noted that for those skilled in the art, Under the premise of general idea of the present invention is not departed from, some changes and improvements can also be made, these should also be considered as the present invention's Protection domain.
