Operation principle explanation
This automatic irrigation system stem device adopts the humidity condition of humidity sensor monitoring soil, after soil moisture is lower than set value, automatic open water pump motor and magnetic valve are filtered the moisturizing realized water head tank, then water head tank self-pressure is relied on to water to this soil, when after the value that humidity reaches required, stop watering.Less than normal and frequently open pump moisturizing and the long problem native system of irrigation time adopts various control pattern for meeting the water head tank outlet pressure when irrigate broad areas, the basis of automatic mode and manual mode increases automatic high pressure pattern, namely the water delivery of across-the-line starting water pump connects irrigation rig and irrigates irrigated area after filter, automatically stops irrigating when humidity reaches setting value.For saving water resource, native system is provided with the function that the rainy day stops irrigation automatically, and when irrigated area rainfall alarm outputs signal (rainy day), PLC terminates to irrigate automatically.Native system also has the functions such as pressure reduction warning before and after motor idle running protection, filter (representing that filter may block).
According to Fig. 5, the workflow that automatic irrigation system stem fills to be described below.
(1), automatic mode
When being set in automatic mode by human-computer interaction interface 11 selector switch, system enters automatic operation mode, now the humidity sensor 32 of two irrigation districts (A district, B district) by plant soil water fraction factually time pass to PLC 21, PLC 21 compares according to the humidity range of the signal of humidity sensor 32 with the applicable plant growth preset, and judging whether needs to irrigate.When detected value is lower than the lower limit arranged, PLC 21 controls the flicker of corresponding Irrigated Area Soils lack of water indicator lamp (redness) and performs automatic irrigation program simultaneously.
Automatic irrigation program is as follows:
First, judge that whether water head tank 2 liquid level is lower than 20%, fluid level transmitter (LT-01) 31 exports the 4-20mA analog signal corresponding with water level to PLC 21, PLC judge water level lower than 20% time, control loudspeaker 43 sounds the alarm and controls water pump 1 motor simultaneously and obtain electric, start water pump 1, open tank and add water with magnetic valve XV-01 automatic watering, liquid level higher than alarm release after 20%, until the motor power-off of water pump 1 when liquid level reaches setting value 90%, water pump 1 out of service, close tank and add solenoid valve for water XV-01 and automatically terminate to add water.
Then PLC 21 judges whether rain sensor 33 is the signal exporting the rainy day, if the rainy day then stops the whole irrigation procedure in each irrigation district; If not the rainy day then opens tank irrigation magnetic valve XV-02 and corresponding irrigated area magnetic valve XV-A1 or XV-B1, rely on water head tank self-pressure to irrigate, when water level lower than 20% time, PLC 21 repeats automatic watering process.When humidity sensor 32 detected value reaches capping value, PLC 21 controls the termination of pumping of water pump 1 motor dead electricity, closes tank irrigation magnetic valve XV-02, irrigated area magnetic valve XV-A1 or XV-B1, terminates to irrigate.
Humidity sensor 32 detected value is in time setting between humidity upper lower limit value, PLC 21 outputs signal soil moisture and is suitable for indicator lamp (green) flicker, when detected value exceedes capping value, the excessive indicator lamp of soil moisture (yellow) glimmers, and reaches the object of monitoring.
(2), automatic high pressure pattern
When irrigated area, area is larger, need high pressure to spray and consider that different plant water requirement is different or kindred plant different growing stages water requirement is different, when needing big yield to irrigate, on the lower side and the frequent starting moisturizing program of water head tank outlet pressure under automatic irrigation pattern, take time and effort, control switch can be selected automatic high pressure pattern for this reason.System enters automatic high pressure mode of operation, now the humidity sensor 32 of two irrigated areas (A district, B district) by plant soil water fraction factually time pass to PLC 21, PLC 21 compares according to the humidity range of the applicable plant growth of the signal of humidity sensor 32 and setting, and judging whether needs to irrigate.When detected value is lower than the lower limit arranged, PLC 21 controls the flicker of corresponding Irrigated Area Soils lack of water indicator lamp (redness) and performs automatic high pressure irrigation procedure simultaneously.
Automatic high pressure irrigation procedure is as follows:
First PLC 21 judges whether the signal of rain sensor 33 is the rainy day, if the rainy day then stops the whole irrigation procedure in each irrigation district, control loudspeaker sounds the alarm simultaneously; If not the rainy day then outputs signal and controls water pump 1 motor and obtain electric, start water pump 1, open high-pressure irrigation magnetic valve XV-03 and corresponding irrigated area magnetic valve XV-A1 or XV-B1 and water is delivered to corresponding irrigated area and irrigates.Control water pump 1 motor power-off termination of pumping when humidity sensor 32 detected value reaches capping value, close high-pressure irrigation magnetic valve XV-03, irrigated area magnetic valve XV-A1 or XV-B1, terminate to irrigate.When humidity sensor 32 detected value is between humidity set upper lower limit value, PLC 21 soil moisture control is suitable for indicator lamp (green) flicker, when detected value exceedes capping value, the excessive indicator lamp of soil moisture (yellow) glimmers, and reaches the object of monitoring.
(3), manual Irrigation
Under manual Irrigation, user can manually arrange the opening sequence of each magnetic valve and the start-stop time of water pump 1 and irrigated area etc. according to actual conditions, and PLC 21, according to different manually operated signals, controls water pump 1 and each magnetic valve.
In present embodiment, for preventing the impurity blocking pipeline, shower nozzle etc. in water quality, two water filter A and B parallel running is provided with as shown in Figure 1 in system, filter inlet and outlet pressure transmitter PT-01, PT-02 export 4-20mA analog signal to PLC, the output alarm prompting when PLC 21 detects that front and back pressure reduction reaches 0.3bar: filter differential pressure is high, filter differential pressure alarm lamp flicker simultaneously, prompting user filtering device may block, and needs cleaning.
For protection motor, prevent water pump 1 motor from dallying, when water pump 1 idle electric current being detected after controller startup water pump, PLC 21 stops water pump automatically, and this setting value sets according to the motor idle electric current value of actual purchase.
Water head tank liquid level lower limit is the initial value (namely 20%) of Operation system setting, generally can not arbitrarily adjust, when causing liquid level unpunctual, if cannot clear up in time, need to reset low liquid level, after cleaning out, still need to revert to initial value.
System upgrade after considering, the factors such as scrap build, reserved corresponding fastener passage in PLC control system, as subsequent use.PLC can also connect host computer by communication interface and carry out data transmission and procedure configuration amendment, also field irrigation corresponding data can be read, simultaneously can online printing related data, in order to inquiry, realize the scientific management of field irrigation, improve field irrigation technology.Because automatic irrigation system stem device of the present invention is with the sled block, CD-ROM drive motor etc. of generator, band wheel, can not only move, the place not having power supply can also be used for, can suit measures to local conditions to use flexibly, well save water resource and reduce irrigation cost.
Automatic irrigation system stem device of the present invention both can be irrigated each plot (irrigation district) by Non-follow control, also can be formed the Automatic Control of Closed control by humidity sensor and controller.Not only prevent from, because water head tank causes the capillary burette of the low irrigation rig of hydraulic pressure not go out water problem because of moisturizing not in time, can rainwater being utilized on rainy day, preventing water resource to be wasted.Larger for irrigated area area, need high pressure to spray and consider that different plant water requirement is different or kindred plant different growing stages water requirement is different, when needing big yield to irrigate, select by automatic high pressure pattern, directly supplied water by water pump 1, neither need to arrange the higher water head tank of water level, turn avoid the on the lower side and frequent starting moisturizing program of outlet pressure, reduce energy consumption.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, as long as within the spirit and principles in the present invention, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
