The device realizes automatic irrigation for fields, and irrigation can be automatically stopped after soil moisture reaches a certain value, which achieves the purpose of saving water, saving time, saving labor and reasonable irrigation. The device is invented for farmers and is low in costs and easy to operate.

Description

A kind of automaton of insufficient irrigation
Technical field
The invention belongs to agricultural modernization field management water-saving technology and automation control appliance field, especially a kind of automaton of insufficient irrigation.
Background technology
The insufficient irrigation technology is to pursue the modern water-saving irrigation technique that the crop water utilization ratio is the highest, take into account crop yield and quality under the lack of water condition.The key that this technology is promoted is that a kind of irrigation method that can effectively control the soil moisture bound will be arranged.
With respect to soil volumetric(al) moisture content or weight water content, soil water potential is generally believed more can characterize the validity of soil moisture for crop.Thereby, can control the bound of soil moisture by the bound of control soil water potential.The soil depressimeter is a kind of conventional instrument of measuring soil water potential that generally uses both at home and abroad at present, owing to advantages such as its volume is little, moderate, easy to carry are extensive use of in the field, for agricultural water-saving irrigation has been made contribution.
The soil depressimeter that uses generally is made up of pot clay end, water-supply-pipe and vacuum meter at present, need the reading of the timely recording vacuum gauge of staff and compare to determine whether lack of water of crop with set desired value, irrigation system is got up by manual operation during irrigation quite wastes time and energy.Full-automatic irrigation system because it involves great expense, is not popularized on agricultural at home as yet.Simultaneously, often think little of for the control of the soil moisture upper limit during irrigation or control undesirablely.
Summary of the invention
The purpose of this invention is to provide a kind of automaton of insufficient irrigation, it is characterized in that, described automaton is that the discharge on the depressimeter connects vacuum meter, and two hall sensors are installed on the vacuum meter; Hall sensor is connected with amplifying circuit by lead, and amplifying circuit is connected with power control circuit by single-chip microcomputer, power control circuit control water supply installation.
Described depressimeter comprises vacuum meter 6, communicating pipe 2 and the pot clay end 1 of discharge 3, repacking; There is water filling port the upper end of discharge, and with rubber stopper 4 and thread cap 5 sealings, side has an interface to be connected with vacuum meter 6, and communicating pipe 2 joins by plastic tube and pot clay end 1 in discharge 3 lower ends.
Pointer syringe needle in the facing up of described vacuum meter, vacuum meter changes magnetic material into.
The range of described vacuum meter is 0~-80kPa, characterize the degree of lack of water with different colors at the scale of this range.
Second hall sensor 15 at the lower limit depressimeter reading place that described hall sensor comprises first hall sensor 8 that is bonded in the upper limit depressimeter reading place that sets in the vacuum meter, set; And the back side in the vacuum meter gauge outfit.
Described water supply installation comprises water pump 12, the water storage tank 13 that is connected with water pump 12 and water-supply-pipe 14.
Beneficial effect of the present invention:
(1) the insufficient irrigation automaton based on soil water potential provided by the invention is a direct-reading, in range ability, can set the different target flow of water, and can control the bound of soil moisture simultaneously, avoid the moisture deep percolation and the fertilizer leaching loss that cause because of heavy irrigation.
(2) the present invention is light simple, cheap, is applicable to the automatic irrigation of crop in farmland, the greenhouse, is easy to promote the certain positive role of performance aspect using water wisely.
Description of drawings
Fig. 1 is the structural representation of the automaton of insufficient irrigation.
Fig. 2 is the vacuum meter enlarged drawing of repacking.
Embodiment
The invention provides a kind of automaton of insufficient irrigation, Figure 1 shows that the structural representation of the automaton of insufficient irrigation.Discharge 3 among the figure on the depressimeter connects vacuum meter 6, second hall sensor 15 at the lower limit depressimeter reading place of first hall sensor 8 at the upper limit depressimeter reading place that sets in vacuum meter, setting; And the back side in the vacuum meter gauge outfit.Two hall sensors are connected with amplifying circuit 9 by lead, and amplifying circuit 9 is connected with power control circuit 11 by single-chip microcomputer 10, the water pump 12 of power control circuit 11 control water supply installations, and the water storage tank 13 and the water-supply-pipe 14 that are connected with water pump 12.
Described depressimeter comprises vacuum meter 6, communicating pipe 2 and the pot clay end 1 of discharge 3, repacking; There is water filling port the upper end of discharge, and with rubber stopper 4 and thread cap 5 sealings, side has an interface to be connected with vacuum meter 6, and communicating pipe 2 joins by plastic tube and pot clay end 1 in discharge 3 lower ends.
Pointer syringe needle in the facing up of above-mentioned vacuum meter 6, vacuum meter changes magnetic material into; The range of vacuum meter is 0~-80kPa, characterize the degree of lack of water with different colors at the scale of this range.
When soil becomes dry gradually, the depressimeter pointer begins to rotate, when it turns to the position, lower limit depressimeter reading place of hall sensor, magnetic material on the pointer of vacuum meter will be given signal of hall sensor, this signal passes to single-chip microcomputer by amplifying circuit, discerns this signal by single-chip microcomputer and comes at the soil moisture upper limit or lower limit; When soil moisture reaches down in limited time, send a signal by single-chip microcomputer and give power control circuit, power supply opening, starting mode of pump, system begins to pour water; After system pours water, move down into the position of pot clay end when soil wetting front, the vacuum meter pointer begins revolution, when being turned back to the hall sensor of the corresponding soil moisture upper limit, this hall sensor is given signal of single-chip microcomputer, single-chip microcomputer identification is judged the back to signal of power control circuit, thus powered-down, and system stops to pour water.
The present invention solves the deficiencies in the prior art, provides a kind of cheap, easy operating, towards the base of peasant household In insufficient irrigation method and the automaton of soil water potential, utilize sensing technology and microelectronics device to soil Moisture is controlled automatically, according to user's actual needs, sets different target water potential values, in the soil lack of water Situation under, realize the automatic irrigation to the rural area, after pouring water after ground moistening arrives to a certain degree system again passable Automatically stop to pour water, reached the purpose of using water wisely, time saving and energy saving, Rational Irrigation.
