A kind of green house sprays drip irrigation control system automatically
The utility model relates to a kind of agricultural spray drip irrigation system, and particularly a kind of green house sprays drip irrigation control system automatically.
Green house is produced the mode of agriculture as a kind of new highly efficient and productive, high-quality, is used widely at home, has also become a kind of trend of countries in the world agricultural development.The moisturizing of crops mainly relies on the spray drip irrigation appliance in the green house, and these class waterworks generally are divided into two parts, and a part is the pipeline that drips, and is embedded in undergroundly, is mainly used in the water spray of melon and fruit and so on; Some is sprayer unit, hangs in the booth, is mainly used in the vegetables moisturizing.All need every day the Plants such as fruits and vegetables are fed water at regular time and quantity, and also mainly rely on now manpower to carry out the operation of open valve, not only consuming time but also require great effort, judge whether to irrigate with experience and estimation simultaneously, easily in the irrigation process, water resource is caused waste.Up to now, a kind of automatic spray drip irrigation control system that is adapted at popularization in China's agricultural greenhouse plantation not yet appears.
Summary of the invention
For addressing the above problem, the purpose of this utility model provides a kind of green house that is adapted at promoting in China's agricultural greenhouse plantation and automatically sprays drip irrigation control system, this system can carry out automatic or manual to the Plants in the green house and open/close aqueduct valve by the program of setting, and carries out the moisturizing of crop.
The purpose of this utility model realizes by the following technical solutions: a kind of green house sprays drip irrigation control system automatically, comprise the two-way water pipeline that control circuit board, humidity sensor, magnetic valve, the two-way of burying in the ground of green house drip pipeline and hang in canopy, water pipeline links to each other with water supply line by magnetic valve with the pipeline that drips, and the keying control of magnetic valve is finished by the control circuit board in the booth; Described humidity sensor is embedded in the soil of booth, and humidity sensor connects control chip, and control chip is embedded in the control circuit board.
Further, described control circuit board has the function of data demonstration and input operation.
Further, described control circuit board can produce multichannel 24V control output signal, to realize the control to multipath electrovalve.
Further, described humidity sensor, but soil moisture in the Real-Time Monitoring booth are to the Plants operation of effectively feeding water.
Further, described spray drip irrigation control system adopts a Switching Power Supply to change the 220V interchange into the 24V direct current, then powers to control circuit board.
The beneficial effects of the utility model are as follows: this control system is applied to single-chip microcomputer control technology in the greenhouse gardening, humidity according to soil in the booth has realized in greenhouse gardening crop being carried out automatic water supplement, not only improve operating efficiency but also avoided the impact of subjective irrigation, reduced the waste of water resource in the irrigation process; Simultaneously, the utility model dependable performance, with low cost, simple to operate being adapted at are promoted in China's greenhouse gardening.
Description of drawings
Fig. 1 is the structural representation that the utility model green house sprays drip irrigation control system automatically
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of green house sprays drip irrigation control system automatically, comprise the two-way water pipeline 4 that control circuit board 1, humidity sensor 7, magnetic valve 3, the two-way of burying in the ground of green house drip pipeline 5 and hang in canopy, water pipeline 4 links to each other with water supply line 2 by magnetic valve 3 with the pipeline 5 that drips, and the keying control of magnetic valve 3 is finished by the control circuit board 1 in the booth.Described humidity sensor 7 is embedded in the interior soil of booth, and humidity sensor 7 connects control chips, and control chip is embedded in the control circuit board 1.Described control circuit board 1 can produce multichannel 24V control output signal, to realize the control to multipath electrovalve 3.
During implementation, humidity sensor 7 is embedded in the interior soil of booth, humidity data in the Real-time Collection booth, and feed back to control circuit board 1, control circuit board 1 compares the humidity limit value of setting in the humidity data that gathers and the control chip, when humidity was lower than the setting value of plant growth requirement, control circuit board 1 control magnetic valve 3 was opened the operation of feeding water.Normal or when being higher than setting value when humidity, stop the feedwater operation.
During implementation, described a kind of green house automatically sprays drip irrigation control system and adopts a Switching Power Supply to change the 220V interchange into the 24V direct current, then gives control circuit board 1 power supply.
The utility model adopts electronic technology automation control, and operating efficiency is provided greatly, has reduced the labour, and the humidity demand of plant growth is carried out Real Time Monitoring, has guaranteed the growing environment of Plants excellence.
Being the utility model preferred embodiment only in sum, is not to limit practical range of the present invention.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should belong to technology category of the present invention.
