Abstract
A water-saving control method for the automatic irrigation (or drip irrigation) system features that a time controller and a moisture controller are used, the moisture sensor of said moisture controller is arranged in the soil of culture region, and the moisture control valve of said moisture controller and the time control valve of said time controller are serially connected in water supplying pipeline.
Description
Technical field:
The present invention relates to crops automatic irrigation or drip irrigation technique.
Background technology:
At present, many crops, especially the cultivation of senior crops tends to adopt automatic irrigation or automatic dripping irrigation system to them, and adopts temporal setting (for example: morning or regularly pouring at dusk) to realize usually the mode of its " control automatically ".In case the program setting of automatic-watering is good, just no matter crops lack of water whether, automatic-watering is carried out to it in the capital on time and quantitatively, do not rain but because air humidity very much not during lack of water although run into when raining or run into, for using water wisely, just can control the automatic irrigation system time-out by the people and water, not hard to imagine, so automatic irrigation system exists " blemish in an otherwise perfect thing " part significantly: it is also poor one step away to leave full automation.Otherwise, just be difficult to avoid people's participation, make troubles to the people.
At present, all kinds of humidity sensors (device) relevant with water come out already, are widely used or use, and " psychrometer " of reflection air humidity (water content) wherein arranged, and " the little water testing instrument " that measure the superhigh precision that contains little water yield in the material, or the like.
Summary of the invention:
The present invention's purpose is:
Allow existing humidity sensor (device) participate in the automatic control of irrigation system, solve " blemish in an otherwise perfect thing " of above-mentioned automatic irrigation system, realize using water wisely.
In order to realize goal of the invention, the key of intending the employing technology is:
On the basis of the automatic control system of regularly the arviculture area being watered by time controller, set up humidity controller again and participate in the automatic control system of this pouring, implement nearby or remote water saving pouring control.
The present invention's characteristics compared with the prior art:
Owing to adopted humidity sensor (device) collected relevant earth humidity or water content data, also participated in automatic control system that crops are watered, for above-mentioned " blemish in an otherwise perfect thing " that the automatic control system that overcomes only dependence in the prior art " regularly pouring " key element is implemented to water, created water-saving advantage.
Description of drawings:
Figure has illustrated of the present invention a kind of than reliable Automatic Control Theory.
1: the irrigation system water supply line; 2: time control valve; 3: the humidity control valve; 4: time controller: 5: humidity controller; 6: the arviculture area; 7: be used for the humidity sensor head (group) that earth water content data are collected.
Embodiment:
If, set humidity sensor head 7 collected humidity data or water content data and be lower than certain data W when (needing pouring), humidity sensor controller 5 promptly drives by the humidity control valve 3 of its control and opens, in the morning or at dusk (the automatic-watering time control of setting by time controller 4) automatic-waterings are implemented in cultivation area 6.If behind rainy day or the rain soon, surface humidity is certain to surpass the original humidity lower limit W data of setting, at this moment, open by the humidity control valve 3 that humidity sensor head 7 collected data just can not allow humidity controller 5 be controlled, as long as humidity control valve 3 and time control valve 2 the two one of close, the program behavior of cultivation area 6 being implemented automatic-waterings just can not take place.
Obviously, by time controlling element and the two pouring automatic control system of forming jointly of earth humidity controlling element, can reach the purpose of water saving to 6 enforcements of arviculture area.
Claims (3)
1. the economical control of crops automatic irrigation or drip irrigation system has: the automatic control system of regularly arviculture area (6) being watered by time controller (4),
It is characterized in that:
Set up humidity controller (5) again, allow it and time controller (4) mutual group paired arviculture area (6) implement the automatic control system of water saving pouring, and the humidity sensor head (7) of humidity controller (5) is directly or indirectly to be arranged in the earth of arviculture area (6).
2. the economical control of crops automatic irrigation as claimed in claim 2 or drip irrigation system, it is characterized in that: described earth position can directly or indirectly reflect arviculture area (6) earth humidity.
3. the economical control of crops automatic irrigation as claimed in claim 1 or drip irrigation system, it is characterized in that: the humidity control valve (3) of described humidity controller (5) control is series connection with the time control valve (2) of time controller (4) control in irrigation system water supply line (1).
