Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Shown in the farmland automatic irrigation metering system of Fig. 1, the utility model comprises an aqueduct 7, in aqueduct, be provided with flowmeter 1 and water pump 4, metering system is also provided with controller 2, drive circuit 3 and soil moisture module 6, and flowmeter 1, controller 2 and drive circuit 3 are connected with vertical compression stabilized current supply 5 respectively; The output of the control end of flowmeter 1 and soil moisture module 6 is connected with controller 2; Controller 2 is connected with water pump 4 by drive circuit 3.
The flowmeter of described farmland automatic irrigation metering system is electromagnetic type flow meter or ultrasonic flowmeter, and flowmeter is provided with signal output part, the flow of water is changed into electric weight and then forms signal transferring to controller.
The controller 3 of described farmland automatic irrigation metering system is made up of single-chip microcomputer, is connected with input keyboard and display screen on single-chip microcomputer.Keyboard is provided with numerical key and shifting bond(s).Be used for inputting and irrigate flow and automatic pumping startup and stop.
The output of the soil moisture module 6 of described farmland automatic irrigation metering system also connects relay, and by amplifying signal input control device, controller is connected with water pump by drive circuit.
In force, soil moisture module 6 arranges in field reconnaissance, is generally embedded in soil 40-60cm depths, and need to determines its crucial threshold value in the time of field capacity 65%, when it is in the time being less than field capacity 65%, needs to irrigate.When soil moisture module 6 lower than set value time, signal is transferred to controller 2 by relay, controller, by drive circuit control water pump 4, is opened water pump 4 and is irrigated.Meanwhile, the flow of measuring by flowmeter 1, and signaling traffic is sent to controller 2, actual total amount and initial setting up value that controller 2 accumulative totals are irrigated contrast, and in the time that irrigation volume equals initial setting up value, disconnect water pump 4 by drive circuit 3.Display screen can show irrigation volume used.
In force, the settings of irrigating total amount are relevant from the water requirement of the different vegetative stages of crop, as being made as the lower limit of water requirement for fixed value.
