Pipe network 2: its effect is the planting lawn region of press water being carried and is assigned to required irrigation.Pipeline by different tube diameters forms, and minute main, arm, hollow billet etc., connect into complete pipe network 2 systems by equipment such as various corresponding pipe fittings, valves by pipelines at different levels.The pipe network more than 2 of modern irrigation system adopts easy constructions, hydraulic performance well and plastic conduit that can corrosion, as pvc pipe, PE manage etc.Meanwhile, should necessary safety device be installed in pipe network 2 as required, as air inlet and exhaust valve, pressure limiting valve, drain valve etc.
Shower nozzle 3: shower nozzle 3, for aqueous dispersion is become to water droplet, is sprayed at planting lawn region more equably.
Fig. 4, spray pattern and shower nozzle 3 combinations:
A) spray pattern: two kinds of the sprinkling of You Quan garden and fan-shaped sprinklings.In production crew to spray be main, fan-shaped to be sprayed at special occasion applicable: corner, rural area, the gradient are large, wind-force is large, single spraying 3 unit.
B) shower nozzle 3 type selectings: while selecting shower nozzle 3, remove the performance that needs to consider itself, as the operating pressure of shower nozzle 3, flow, range, combination application rate of sprinkler irrigation, spray outside fan-shaped angle could regulate, also must consider the factors such as permission application rate of sprinkler irrigation such as soil, plot size shape, lawn species, water condition, user's requirement simultaneously.At present, lawn spray irrigation system generally all adopts and buries elevation (over-and-under) type lawn nozzle 3.
C) shower nozzle 3 combining forms: be that many shower nozzles 3 are worked simultaneously during sprinkling irrigation, combination principle is not blank, and has the higher uniformity, conventional four kinds of forms of shower nozzle 3 combinations: arranged in squares, equilateral triangle layout, rectangular arrangement and isosceles triangle are arranged.
Fig. 3 is circuit theory diagrams of the present utility model, and wherein, M is water pump, and J is relay 5, and B is warning device 4, and LED is display unit, and IC is controller 7, and RT1 is air temperature sensor 8, and RT2 is soil temperature sensor 9, and RT3 is checkout gear 10.
This device can reach following effect:
Data acquisition function: can automatically gather, treatment temperature data.
Irrigation control function: have automatic irrigation, manually irrigate two kinds of patterns, user can select Irrigation as required flexibly; Can on-the-spot temperature, humidity limit value be arranged and be revised; Can complete parameters such as irrigating initial time, dwell time, sprinkling irrigation time by controller 7 or background monitoring system arranges.
Presentation Function: background monitoring system can be joined large screen display, the various ways such as figure, form dynamically show whole irrigation district ruuning situation, accurate, intuitive, clear.
Warning function: when irrigation system breaks down, as pipe burst etc., stop immediately water pump operation, and report to the police.
Data processing function: the various data processing functions such as the statistics that background computer can completing user proposes, storage, inquiry, and the form that requires of printable user.
In Fig. 1, Fig. 2, Fig. 4, during the utility model work, the temperature of soil is measured in a plurality of root system depths that probe into shallow root vegetation by different location of No. 1 DS18B20 soil temperature sensor 9 minutes, No. 2 DS18B20 air temperature sensor 8 minutes are a plurality of to be placed in air by different daylighting points and to record temperature at that time, then imports the data that record into single-chip microcomputer and carries out analyzing and processing.By the programming in control system and with each device between be connected, the data that No. 1 temperature sensor and No. 2 temperature sensors are measured are imported controller 7 into, then controller 7 is to these data analysis judgements, find out maximum temperature and minimum temperature value in each sensor 24h, then respectively to its ask poor draw soil temperature amplitude of diurnal variation 1. with daily temperature range 2., obtain again the value of (1.-2.), when this is worth >=1.5 ℃ (according to different regions, the temperature of period and determine) time just start to export a signal, make the switch opens of sprinkling irrigation system, start to irrigate, the time of irrigating is also determined by single-chip microcomputer, can find the relevant formula t=2.83h that finally obtains a result, therefore the time that the each control pump switch of controller 7 is opened is all 2.83h, can guarantee that like this top limit of humidity is between 85%-95%, error is little.The temperature value that simultaneously No. 1 sensor and No. 2 sensors are measured also can show screen display in real time, so that we check, when system goes wrong as problems such as temperature over-range, pipe burst, water pump lack of water, shower nozzle 3 obstructions by signal back controller 7, controller 7 sends alarm signal, display unit display alarm pattern, warning device 4 sends alarm voice, and irrigation stops, and waits for administrative staff's maintenance.For large-scale farmland or gardens, can by USB interface chip, import the data that record into calculator, manually check and analyze.
These are only specific embodiment of the utility model, but technical characterictic of the present utility model is not limited to this.Anyly take the utility model as basis, for realizing essentially identical technique effect, done ground simple change, be equal to and replace or modification etc., be all covered by among protection domain of the present utility model.
