The automatic control system can realize online automatic monitoring and controlling of soil moisture content, improves agricultural seasonal drought conditions, guarantees irrigation uniformity degree, converts crop water supply into accurate water supply according to needs, ensures agricultural production stability, and simultaneously increases utilization of water resource.
Description
Technical field
The utility model relates to a kind of automatic control system, relates in particular to the underground drip irrigation automatic control system.
Background technology
Be called water and coerce by arid, the caused interference of lack of water the plant normal physiological function.The Li Wenhua of Xibei Univ. of Agricultural ﹠ Forest Science ﹠ Technology etc. studies show that: different soils moisture handles that stem to seeds is heavy, root is heavy, the root of total biomass and seeds is heavy, the total biomass influence significantly, blade relative moisture content and the individual plant water consumption of plant all reduce with the reduction of soil moisture, have only when soil moisture content is higher than a certain threshold value, plant could survive, during higher a certain threshold value, plant just can have bigger biomass on this.Therefore,, soil moisture content is controlled between plant survival threshold value and the maximum biomass threshold value, promptly irrigates near the threshold value, just can economize on water in a large number and guarantee plant normal growth if can grasp the water requirement situation of change of plant.At present, the intelligent control appliance of water-saving irrigation depends on import, and use cost is bigger.
The utility model content
The underground drip irrigation automatic control system that technical problem to be solved in the utility model provides and a kind ofly supplies water as required, use cost is low.
For addressing the above problem, a kind of underground drip irrigation automatic control system described in the utility model is characterized in that: this system is made up of CSRC calculator, irrigation monitor controller, hub, several soil moisture sensors and several valve positioners; Described CSRC calculator is by wireless communication module and the wireless connections of described irrigation monitor controller; Described irrigation monitor controller links to each other with described several valve positioners with described several soil moisture sensors respectively by described hub; Described several soil moisture sensors are evenly distributed in the soil; Described several valve positioners all are connected with magnetic valve.
The quantity of described soil moisture sensor is consistent with the quantity of described valve positioner, magnetic valve.
The utility model compared with prior art has the following advantages:
1, owing to is provided with soil moisture sensor in the utility model, this sensor has high accuracy, high sensitivity, high stability, good airproof performance, the middle use of can placing into the soil for a long time, and uncorroded characteristics, therefore, realize the online auto monitoring and the control of soil moisture content, improved agriculture seasonal drought water shortage status, guaranteed uniformity of irrigation water appilcation, make crops supply water and change as required precisely water supply into, guarantee the agricultural production stable yields; Simultaneously, also improved the utilization ratio of water resource.
2, adopt the utility model can change the general layout of the intelligent control appliance of water-saving irrigation, realized the intelligent control production domesticization of water-saving irrigation first by import.
3, the utility model is precisely irrigated the demonstration area in being applied to Xiyuan, municipal administration mansion square, Jiuquan, and fault-free is moved more than 200 day continuously, has realized accurate irrigation well.
4, the utility model water-saving and yield-increasing remarkable benefit.Adopt the utility model to carry out the Based Intelligent Control underground drip irrigation and supply water and supply water more accurate more in time than common drip irrigation, realized that crop supplies water as required, relatively the volume increase of under-film drip irrigation cotton is 22.97 kilograms/mu, and the saving rate has improved more than 15%; The routine of comparing furrow irrigation is increased production 76.78 kilograms/mu, and water-saving rate improves more than 25%.
5, the utility model is easy to operate, use cost is low.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-CSRC calculator 2-irrigates monitor controller 3-hub 4-soil moisture sensor 5-valve positioner 6-magnetic valve
Embodiment
As shown in Figure 1, a kind of underground drip irrigation automatic control system is made up of CSRC calculator 1, irrigation monitor controller 2, hub 3, several soil moisture sensors 4 and several valve positioners 5.
CSRC calculator 1 is by wireless communication module and 2 wireless connections of irrigation monitor controller; Irrigating monitor controller 2 links to each other with several valve positioners 5 with several soil moisture sensors 4 respectively by hub 3; Several soil moisture sensors 4 are evenly distributed in the soil; Several valve positioners 5 all are connected with magnetic valve 6.
Wherein the quantity of soil moisture sensor 4 is consistent with the quantity of valve positioner 5, magnetic valve 6; Hub 3 is the RS-485 bus.
Operation principle: CSRC calculator 1 regularly sends the data acquisition request by wireless communication module to irrigating monitor controller 2; Irrigate the request of 2 pairs of central supervisory control comuters 1 of monitor controller and analyze, and send data acquisition command to corresponding soil moisture sensor 4 by hub 3RS-485 bus; Soil moisture sensor 4 is gathered the soil moisture content data, by the RS-485 bus data is returned to then and irrigates monitor controller 2, returns to CSRC calculator 1 by irrigating monitor controller 2 again; CSRC calculator 1 according to control algolithm to the processing that performs an analysis of soil moisture content data, and according to result to irrigating monitor controller 2 sending valve door switch requests, through irrigating the control command of monitor controller 2 to valve positioner 5 transmit button valves; Valve positioner 5 is according to the on off state of control command control magnetic valve 6, and relevant information is returned to CSRC calculator 1 via irrigating monitor controller 2.Go round and begin again, constitute the automatic irrigation system of a closed-loop control.
