Description
Technical field
The invention belongs to control system technical fields, more particularly, to the intelligent environment protection trickle irrigation control of wall greening maintenance
System.
Background technique
Currently, the maintenance of wall greening generally uses drip irrigation system, weeper is opened up by the bottom in outlet pipe, by water
Hole carries out trickle irrigation, maintenance to wall greening.Drip irrigation technique has the characteristics that superior water-saving, and water use efficiency is up to 95% or more.
But in trickle irrigation, if the hydraulic pressure to supply water is unstable, it is not able to maintain stable trickle irrigation speed, thus will appear
The case where speed of trickle irrigation is very slow when plant hydropenia is more serious, and plant cannot get enough moisture or plant not water shortage when drip
The case where speed of filling is but very big, waste water resource.
Based on this, there is constant-pressure irrigation system, so-called constant irrigation refers to that irrigation water pressure is constant at optimal use
Water pressure range, not changed a kind of irrigation water supply mode because of irrigation water changes in flow rate.It has uniformity of irrigation water appilcation
High, pipe-line equipment is not easy the feature being damaged with water-saving energy conservation.
As the patent of Publication No. CN107047235A discloses such a efficient water-saving irrigation system equipment, including
Water supplying pipe, water pump, pressure gauge, controller, constant pressure frequency conversion equipment and more weep pipes；One end of water supplying pipe is water inlet end, water inlet
End is installed with water pump；Weep pipe is connected to water supplying pipe, and solenoid valve is equipped on every weep pipe, and battery valve is electric with controller
Connection；Water pump and pressure gauge are electrically connected with constant pressure frequency conversion equipment.
The patent during the work time, by pressure gauge and constant pressure frequency conversion equipment, is able to maintain the stabilization of hydraulic pressure.Make
When with the product of the patent, after setting hydraulic pressure, system can convey moisture into weep pipe according to the hydraulic pressure of setting, improve drop
Hydraulic pressure consistency when filling.
But existing irrigation system is all that timing is sprayed water, that is, the frequency that water spray is set in controller, to one
After fixed time interval, controller will control system progress trickle irrigation.Although in this way, the case where staff can be according to weather
The frequency of water spray is adjusted, agrees with the frequency of water spray with climatic environment as far as possible.But it many times, still will appear plant
System has carried out trickle irrigation when object does not need moisturizing or plant needs the case where system is but timely progress trickle irrigation when moisturizing, this
A little situations are all unfavorable for the healthy growth of plant.
Summary of the invention
The present invention is in view of the above-mentioned problems, provide a kind of intelligent environment protection drip irrigation control system for wall greening maintenance.
Base case provided by the invention are as follows:
