Description
Technical field
The present invention relates to a kind of computer software and hardware system regions, and in particular to ecological irrigated area intelligent and high-efficiency management system.
Background technology
Irrigated area generally refer to reliable water source and draw, the filling of defeated, canal for water distribution system and corresponding drainage channelIrrigateArea, be
The product of economical activities of mankind, with the development of social economy.Irrigated area is a semi-artificial ecosystem, and it is to rely on
The light of natural environment offer, heat, soil resource, add the artificial regulatory such as the crop artificially selected and the crop-planting ratio of arrangement
Means and constitute one have the open ecosystem of very strong social nature.
Irrigated area has otherness because area is big, fill discharge structure distribution, physical features height differs, agrotype is various etc.
Feature, causes same time different zones liquid manure situation and there may be larger difference, this causes periodically to patrol, pour water,
Labor management pattern based on fertilization mode expends substantial amounts of manpower, it is impossible to realize fertilising of supplying water on demand in time.In addition do not have
Pouring water, applying fertilizer for standby foresight, is unfavorable for reducing because of the field drainage that precipitation is produced, easily occurs not saving after paddy field is poured water
The phenomenon of a large amount of water, fertilizer, medicine is taken away in rainfall, external draining, causes pollution of area source.
The content of the invention
There is provided a kind of good, the reliable ecological irrigated area intelligence of benefit is high exactly for above technical problem by the present invention
Imitate management system.

In weather forecast information be automatically imported from network weather forecast api interface and participate in calculate.Water level/the moisture transducer 2,
Wireless transmission method is used between water quality monitor 3 and central computer 1.Water deficit diagnosis system on the central computer 1
The acquisitions of 7 pairs of crop canopies infrared images 8, nitrogen acquisition of the diagnostic system 9 to crop canopies visible images 10 that wane of uniting are equal
It can be shot using unmanned plane or aerostat platform, and water, the nitrogen that picture processing is obtained wane diagnosis achievement in irrigated area landform
It has been shown that, when irrigated area area is smaller, shot using smart mobile phone on figure, and handled with software is installed on mobile phone, then with
The shared data of heart computer 1.The water demand of crop based on weather forecast run on the computer（ET）Prediction program 5, water
Point wane diagnostic system 7, nitrogen wanes the crop time of infertility most suitable field day by day that diagnostic system 9 draws with the experience of planting for a long time
Liquid manure amount scope ensures target to irrigate.The water demand of crop run on the computer（ET）Weather in Prediction program 5 is pre-
Count off is automatically imported from network weather forecast api interface according to 6 and participates in calculating, and its algorithm is to be substituted into using the information of weather forecast
The models such as the Hargreaves methods of amendment, simplified Aridity index, intelligent algorithm, time series method, calculating obtains reference crop steaming
Tatol evapotranspiration（ET0）, according to ET0It is multiplied by the crop coefficient of specified crop（Kc）, finally give the water demand of crop（ET）.
Embodiment 1：Experience is planted according to crop for a long time, the optimal field water layer day by day in its time of infertility can be provided（Or
Soil moisture content）Scope, or according to some plant physiology Actuality Monitoring means, needing day by day for following a period of time crop can be predicted
Water.Water demand of crop prediction based on data of weather forecast 6 can calculate following 5 to 15 days（Specific number of days depends on the weather pre-
Report prediction number of days）The water that interior irrigated area is lost by Crop transpirstion and Evaporation among plants, data of weather forecast 6 is contained to drop simultaneously
The prediction of water, and field leakage can pass through field water level（Moisture）Speculated, also can rule of thumb be drawn.
By the optimal field water layer day by day of crop（Or soil moisture content）Scope is as target is ensured, using monitoring field
Water level moisture transducer 2 and the water deficit diagnostic system 7 based on crop canopies infrared image 8, obtain water consumpation it is real-time
Situation, with reference to parameters such as the crop reference evapotranspiration with foresight, precipitation, field leakages, is obtained with long-term observation
The crop time of infertility, optimal field water scope is irrigated target day by day, and control manual priming's amount makes field water fall optimal
While the water scope of field, it is kept low as far as possible, vacates larger field water capacity, it is fully sharp to store rainfall
With rainfall resource, reduce field drainage and cause pollution of area source, realize efficient, saving, the water and fertilizer management of emission reduction.
Example 1：The most suitable field depth of water of paddy rice growing stage is 0-60mm scopes, and current field water level 30mm, the depth of water is less than
10mm begins to pour water, and normal irrigation way to manage is that field water level starts quota irrigation 30mm less than 10mm.Below by 15

By comparing, it is found that the irrigation method of ecological irrigated area intelligent and high-efficiency management system of the present invention can be in 15 days futures
Field water calculated, and formulates that irrigation quantity is less, make full use of the irrigation of natural rainfall to instruct, and it is 35mm to make irrigation quantity,
Displacement is 0mm；And normal irrigation mode can only decide whether irrigation according to same day field aqueous condition is judged, easily produce and pour water
The phenomenon of rainfall immediately, causes to add irrigation volume, field also produces draining afterwards, irrigation quantity is increased to 60mm, and displacement increases
Add to 23mm.
For uncontrollable precipitation, such as precipitation exceedes the situation of field maximum water-storage, in order to ensure plant just
It is frequently grown, then must carries out draining, can be by the water quality testing meter 3 of ecological ditch first and last by the purified treatment of eco-drainage ditch
Monitor clean-up effect.
Central computer 1 is initial daily to be read with this water consumpation situation using water level/moisture transducer 2 automatically, and from
The dynamic data of weather forecast 6 that obtains predicts following 15 days ET, precipitation, leakages day by day, and according to the preset crop of operator 12
Optimal water consumpation scope, estimates irrigation volume day by day and displacement, shows operator 12.Operator 12 may be configured as trustship mould
Formula, the then row's of filling control is voluntarily completed by central computer 1；Operator 12 may be configured as manual mode, then provided by operator 12
Amount carry out filling row, central computer 1 according to operator 12 manually fill discharge capacity update second day basic data again.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and implement according to this, and it is not intended to limit the scope of the present invention.It is all according to the present invention
The equivalent change or modification that Spirit Essence is made, should all be included within the scope of the present invention.
