When being square due to watering area, it is overlapping to reduce watering, can save and spreads the water yield than arc watering, in the present embodiment, shower nozzle Angle of longitudinally effectively spraying water is θ, can only cover a portion during swinging every time.Assume to need to be divided into n area Domain could all cover whole effective active area, speed when calculating nozzle right, rotating upwardly and downwardly, and when being considered as line feed Alt time.If whole covering needs to be divided into n region, going out water speed v0Under, shower nozzle unit interval water yield is q, For ensureing watering uniformly, set watering circulation for m wheel, then when actual watering total amount is q0When, the water yield of spreading often taken turns is q0/m.
Then in every wheel watering, in each region, watering amount is:
Q '=q0/(m·n)
Each region watering time is all equal, is:
t = q &prime; q = q 0 / ( m &centerdot; n &centerdot; q )
The speed calculation that then during the watering of i region, nozzle right rotates is as follows:
&beta; i = 2 arctan s &centerdot; n d &centerdot; i
ωii/t
Wherein, βiFor shower nozzle when region i sprinkles water nozzle right rotational angle, t be rotation time, wiFor left-right rotation speed Degree, s is street lamp post spacing distance, i.e. s1Or s2.
In the present embodiment, equation is tiltedly thrown by object:
h - h = v 0 sin &alpha; &centerdot; t - 1 2 g &centerdot; t 2
R=v0cosα·t
Solve
t - v 0 sin &alpha; + ( v 0 sin &alpha; ) 2 + 2 g h g
Can ask
Meanwhile, with nozzle right uniform rotation, the lift of water spray is also changing, and the computational methods of lift equation of change are such as Under:
r ( t ) = i n * d 2 1 + tan ( &beta; i 2 - &omega; i t )
Simultaneous equations obtain
v 0 2 sin 2 &alpha; 2 g + &lsqb; 1 + 1 + 4 g h v 0 3 ( 1 - cos 2 &alpha; ) &rsqb; = i n * d 2 1 + tan ( &beta; i 2 - &omega; i t )
Therefore, h in formula, d, v0βi, it is it is known that the function of α then can be obtained.
Preferably, after the actual water yield of sprayed calculating, pollutant, airborne dust are veritified by atmosphere quality monitoring device Concentration, if reaching safe concentration, can close shower nozzle.If not up to, repeating to sprinkle water.Start in continuous n Sprinkler In the case of, air quality monitoring module monitors to air pollutant concentration be still above threshold value, exclusion extreme environment feelings Under condition, that is, estimate sprinkler system fault at this, quick response is carried out by mobile terminal, the mobile terminal in the present embodiment is permissible Using smart mobile phone or other intelligent movable equipment, in the present embodiment, air quality detecting device can be in each street lamp lamp Arrange on bar, of course for cost-effective it is also possible to be grouped street lamp by region, one Detection of Air Quality of every group of setting Device, realizes the covering detection to whole region, each detection means setting identification module in region, carries out unique Identification and record position information, when a failure occurs, can will comprise identity code and specific positional information Warning information is transferred to mobile terminal, can greatly improve the efficiency of maintenance.
