Description
Technical field
The present invention relates to automatic irrigation control technology field, be specifically related to a kind of multipurpose can ensure that plant is at the automatic irrigation system of different growth periods to water demand of having.
Background technology
The growth of plant be unable to do without water, and traditional irrigation method is man-made irrigation.People are irrigated plant by the experience of oneself, to meet the demand of plant for water.Traditional irrigation method needs a large amount of artificial participations, and irrigation efficiency is not high, extremely low to the availability of water.
Along with the development of the development of technology, particularly technology of wireless sensing network, irrigation technique is changed to automation gradually by manual.Relative to cable network, radio sensing network has networking convenience, disposes the features such as flexible, in extensive range; And can measure in real time many kinds of parameters such as environmental temperature, ambient humidity, intensity of illumination, soil moisture, wind speed, rainfalls, automatically calculate and irrigate institute's water requirement, the control irrigation time, the moisture supply of effective guarantee plant.Use the irrigation system of automation to substitute people to realize irrigating, make the technical merit of irrigating obtain great development, substantially increase the availability of water, saved a large amount of water resources.
The automatic irrigation system that current China commonly uses can be divided into SECO irrigation system and Intelligent irrigation system.SECO irrigation system is furnished with controller, magnetic valve, soil moisture sensor, rainfall sensor etc., is controlled by timing irrigation.Intelligent irrigation system, by measuring meteorologic parameter (temperature, humidity, rainfall, wind speed etc.), utilizes parameter threshold Controlling solenoid valve to irrigate.But, all there is certain problem in these irrigation systems existing:
1, bulky.The volume of irrigation system interior joint is excessive, can only be deployed in fixing position for a long time;
2, high to the requirement of power supply.These irrigation systems need the DC-voltage supply of at least 24V usually, and some even needs the alternating voltage of 220V to power, and is difficult to the requirement meeting flexible deployment;
3, most systems is when irrigating execution design, adopts and uses electronic valve to carry out the mode controlled at running water pipe place, does not have to consider the Irrigation Problems in retaining situation with no pressure, higher to the requirement of water resource;
4, function singleness, needs too much artificial participation, is difficult to adapt to complicated irrigation requirement;
5, intelligence degree is not high, can only provide in a kind of environment or random environment to water management, can not irrigate targetedly according to the different demands of plant to moisture, be unfavorable for the growth of the plant to growing environment sensitivity.
In sum, current existing automatic irrigation system, still be difficult to meet current agricultural, gardening etc. to the technical need of irrigating, need a kind of miniaturization badly, be applicable to multiple Water Supplies and variety classes plant different growth periods can be met to the automatic irrigating control system of water demand, to improve the automation of irrigation system, intelligent level and range of application, and dropped in practical application.
Summary of the invention
The object of the present invention is to provide and a kind ofly can be applied to different occasions, for different types of plant (particularly to environment than more sensitive plant) provides the automatic irrigation system of the moisture that to adapt with its growth cycle.This system dispose and easy to use, monitor that accuracy is high, control effects good, and the different water source supply of running water, retaining with no pressure two kinds can be applicable to.
For achieving the above object, the grid that is made up of a master controller, multiple sensor node and multiple actuator node of the present invention.Sensor node distributed deployment diverse location in the environment (as shown in Figure 1), is responsible for the temperature of collection different monitoring points, humidity, illumination and soil humidity information, and sends to master controller by wireless transmission method.Position suitable in the environment disposed by master controller; By the temporal information of clock module determination whole system, according to the floristics information preset, which kind of growth cycle automatic decision plant is in; Utilize the environmental information that sensor node collects, generate rational control strategy, and control signal is wirelessly sent to actuator node.Actuator node wirelessly receives the control signal that master controller transmits, and drives the direct current external tapping of 5V voltage, for external magnetic valve or small pump provide driving force, makes whole system reach Based Intelligent Control effect.
The present invention, according to system time information and default floristics, determines the growth cycle of plant, and the environmental parameter of foundation perception, the different growth periods for plant generates irrigation strategy and realizes automatic irrigation.Compared with existing automatic irrigating control system, the present invention not only can realize irrigating the self adaptation of variety classes plant, additionally provide the adaptive capacity to the different water supply system such as running water, retaining with no pressure, overcome that existing system function singleness, the scope of application are little, the irrational shortcoming of irrigation control.
