According to certain area coverage paddy field topographic features, using the paddy field of highest order as conveying ground, first main suit, the management and control devices of water resource can be the channel gate of gravity-irrigated area, well-irrigated area or the suction pump of lifting water irrigation district, the magnetic valve equipment etc. of pipeline water delivery; Meanwhile, in the paddy field of lowest order, set up plash as draining output point.

Under rice crop growth needs water and atmospheric evaporation effect, the water layer in paddy field can reduce by nature, for Fig. 1 schematic diagram: when the water layer of D Tanaka is lower than setting height, the intelligent water layer control and regulation sensor of D Tanaka and Intelligent automatic-control system will open the flashboard in D-C field automatically, allow the water of upper C Tanaka flow automatically to the next D field and realize irrigating; When the water layer of the next D Tanaka reaches the needs height of setting gradually, the flashboard that intelligent water layer control and regulation sensor and Intelligent automatic-control system will close D-C field automatically stops water delivery; When the water in upper C field flow into the next D field cause self water layer lower than setting height or inherently lack of water needs to irrigate time, the Based Intelligent Control water layer of C Tanaka regulates sensor and Intelligent automatic-control system will open C Tian Yugeng upper B field flashboard upwards Tian Yaoshui, by that analogy, until fully-automatic intelligent robot control system(RCS) start upper A field channel gate, water pump, magnetic valve or etc. water delivery, water supply plant realize automatic water-saving irrigation in whole region.

Owing to raining or other factors, when the water layer of A Tanaka is higher than setting height, the intelligent water layer control and regulation sensor of A Tanaka and Intelligent automatic-control system will open the flashboard between A-B ridge, to the next B Tanaka free-draining, when A water in field layer is reduced to normal setting height, flashboard cuts out automatically; In like manner, successively realize draining, until the draining pump that fully-automatic intelligent robot control system(RCS) starts lowest order D field realizes draining.

The invention has the beneficial effects as follows, after adopting above-mentioned Automatic Control technical scheme, on the one hand, can the accurate water layer that needs in field paddy rice each vegetative period of all automatic measurement and controlling, significantly save Rice Cropping water consumption, realize the scientific farming method of rice water-saving irrigation control; On the other hand, the labour intensity of the person that significantly can alleviate agricultural rice growing, economizes labor time, and reduces labour cost, liberates the productive forces.
