The mixed liquid manure mixed liquor of former water irrigation system, fertilization system flows out outlet pipe, enters into irrigation district below, and then irrigate crops through magnetic valve 18.Described in irrigation district, often organize on the branch road of irrigate band and a magnetic valve 18 is housed, each branch road is parallel-connection structure.
Siemens S1200 series switch board selected by described irrigation control system PLC irrigation control cabinet 16, touch-screen 17 selects prestige synthetic fibre (MT8100) series, realize the digital output modul to irrigating by the button on touch-screen 17, Fuji FNRO series selected by frequency converter 21.
Irrigation control mode is divided into control manually and automatic control at regular time and quantity.In irrigation district, often organize on the branch road of irrigate band and a magnetic valve 18 is housed.When can realize automatically controlling by programming, when certain crops reach the time needing to irrigate, then open the magnetic valve controlled on this group branch road on time.Raw water pump electrifying startup, water-injection irrigation in main line.Detected the instantaneous delivery of former water in main line simultaneously by turbine flowmeter 8, so just according to irrigation time, can calculate and irrigate the former water yield used.Nutrient solution concentration needed for PLC can grow according to farming and the injection rate of former water, calculate the injection rate of nutrient solution, injecting nutrient solution, so just achieving the automatic control of the Fertigation to crops by controlling measuring pump in main line.Both can irrigate successively by each magnetic valve 18 during irrigation, also magnetic valve 18 all can be opened and irrigate simultaneously.No matter adopt which kind of irrigation method, as long as at the end of irrigating, first close raw water pump 3, then shut electromagnetic valve 18.
Can be realized by PLC irrigation control cabinet 16: 1, the control irrigation time; 2, mix and blend two kinds of nutrient solutions; 3, realize self-timing and quantitatively complete irrigation, 12 plans can be realized at most, can independent assortment need use plan group number; 4,12 groups of magnetic valves can be controlled simultaneously, and the setting of irrigation time and Application Ratio can both be entered separately to each magnetic valve; 5, system has the function that frequency converter is reported to the police, water flow switch is reported to the police and overcurrent is reported to the police; 6, the inquiry of historical data that this runs can be realized.
System can realize running 12 groups of plans at most.The time that the plan that wherein can set in the works starts and lasting time, the measuring pump numbering that the nutrient solution needs that can select needs to add control and the magnetic valve numbering that needs are opened.And can arrange separately each magnetic valve and measuring pump.As shown in Figure 3.
Rich water mixed liquor is stirred in the effect of mixing pump part, makes it more even.Therefore need according to actual conditions, carry out manually opened.When needs stir, manually opened, mixing pump will stop after 1 hour automatically in operation, if run duration has special circumstances or has satisfied the demand, and can hand brake at any time.Timing controlled: mixing pump automatically stops after startup brings into operation 1 hour, this part needs the timer used in system to realize.Non-follow control: if midway needs to stop, then have corresponding switch to disconnect, mixing pump is stopped.As shown in Figure 4.
Phase sequence is reported to the police: phase sequence alarm portion adopts phase sequence relay, and under normal circumstances, protector connects normally closed electric shock; be in conducting state, after phase sequence is made mistakes, phase sequence relay is automatically received and is often opened electric shock; be in off-state, at this moment PLC just can detect that this changes, thus produces phase sequence warning.
Raw water pump overcurrent warning: raw water pump overcurrent is reported to the police and mainly relied on electrothermal relay to realize, and when current is excessive, will produce larger heat, and when heat acquires a certain degree, relay disconnects, thus creates overcurrent warning, also protects raw water pump.
Frequency converter overcurrent is reported to the police: when the electric current flowing through frequency converter exceedes rated current 10%, be considered as overcurrent, then often can be held by normally closed becoming by the switch in the middle of frequency converter and PLC, thus create overcurrent alarm signal.
Raw water pump water flow switch report to the police: in internal system, a preliminary surveying can be carried out to the instantaneous delivery of raw water pump, if the umber of pulse of instantaneous delivery in 3-5s lower than certain value, then think that raw water pump does not have current, will water flow alarm be produced.
