Embodiment
Embodiment
As shown in Figure 1-2, a certain moment wind direction is east, after sensor sensing to wind direction and wind speed, by signal transmission to single-chip microcomputer, drawing after sequential operation on single-chip microcomputer should to the water column pressurization x kPa being oriented east, should to being oriented water column pressurization y kPa in west (obviously, y<x), now Single-chip Controlling Master Control Room gives the pressurization y kPa that all supplies water, therefore should supplement the pressure of (x-y) kPa to the water column being oriented east bottom jet pipe, be nrad/s by calculating the rotating speed of impeller, direction Chao Dong.If the energy provided by wind-force can not meet rotation speed requirements, then provide dump energy to keep the stable of rotating speed by small electromotor.
Direction due to fan be towards with wind in the opposite direction, namely the direction of maximum pressure is needed, therefore be oriented center line with impeller, be gradual change to pressure effect during the transition of both sides gradually, namely muzzle velocity is by the minimum speed gradual change of upwind maximal rate to down wind.Like this, just achieve desired, avoid the impact of wind on sprinkling irrigation, make the scope of sprinkling irrigation and effect reach desired value.
Utilize wind energy first will know wind direction and wind speed, can be realized by wind direction, air velocity transducer.In a slice greenery patches that entirety controls, according to greenery area and topographical conditions, multiple observation station can be set, reach the overall effect be suitable for make the sprinkling irrigation system after adjustment.
The motion state of the little water droplet that sprinkling irrigation system sprays is a kind of oblique upper paraboloiding movement, is subject to the impact of self gravitation and air drag in this process.Due to shower nozzle rotary water jet, each moment has and sprays from shower nozzle towards different water columns.Assuming that wind can not change direction at short notice, then wind-force to its equidirectional water column act as acceleration, and deceleration is act as to the water column contrary with its direction.In order to consistent before adjusting spray field and having wind, then should adjust muzzle velocity and the exit angle of different directions water column.Considering that again shower nozzle is in higher speed rotation status when spraying water, if change water spray angle, namely allowing spout continuous adjustment direction in rotary course, like this will be very high to the requirement of strength of shower nozzle, be also just easy to damage simultaneously.Therefore, reach by changing water column muzzle velocity the object utilizing wind energy to realize normal sprinkling irrigation.
People often note less than the impact of weather on sprinkling irrigation.Such as, staff often sprays after sprinkling irrigation system being opened all day, and during high noon, illumination is strong, and the water droplet be sprayed onto on plant leaf blade just serves the effect of convex lens optically focused this moment, is easy to plant leaf blade to burn; Rainfall reach certain level, soil moisture large in, plant is not in exsiccosis, does not need to spray.
In sprinkling irrigation, do not need to measure intensity of illumination high precision, thus select photo resistance-voltage conversion circuit to control to carry out induction.What obtain like this is DC voltage, facilitates single-chip microcomputer identification to utilize.
Soil humidity sensor does not need high-acruracy survey equally, therefore adopts resistance-type or capacitive dew cell, and in conjunction with voltage conversion circuit, the DC voltage input single-chip microcomputer obtained controls.
Optical sensor and soil humidity sensor combine the programming Control to system carries out intellectuality, the basis of Automated condtrol is exactly single-chip microcomputer, and the core of controller is single-chip microcomputer.
In conjunction with the wind-force air velocity transducer that Part I is spoken of, the electrical signal data that these sensors gather will be transferred to single-chip microcomputer and process, and this wherein also needs many group experimental datas to carry out sequencing setting.After setting, single-chip microcomputer exports digital quantity, and digital quantity through D/A conversion circuit input voltage or electric current, thus controls whole system.
When soil humidity sensor senses that soil moisture is greater than some values time, single-chip microcomputer can control system quit work; When optical sensor senses that intensity of illumination is greater than a certain value, quit work by single-chip computer control system equally.
Bernoulli equation is also called " pressure equation ", and it is an important relationship formula in One-Dimensional flows problem, and also has basic importance in the field of whole incompressible, time independent fluid mechanics.Bernoulli equation be desirable barotropic fluid have make steady motion under the effect of gesture body force time, the equation of the expressive movement fluid mechanical energy conservation that the equation of motion (i.e. Eulerian equation) obtains along streamline integration.For the incompressible homogeneous fluid in gravitational field, equation is p+ ρ gh+ (1/2) * ρ v^2=c.Flowing medium velocity increases, and pressure just reduces; Speed reduces, and pressure just increases; Speed reduces to zero, and pressure just reaches maximum (should equal stagnation pressure in theory).The present invention utilizes this principle, the pressurization of upwind water column is accelerated, thus realizes windproof object.
