The detection module 26 comprising pH value and EC value sensor is arranged close to irrigated area
Main line on, so as to the pH value in accurate detection rich water and EC value.Will be in real time
Detected value sends PLC control program to, according to the pH value of program inner setting and EC value
Deviation between setting value and detected value controls the injection rate of nutritional solution, in relatively short period of time
Can reach fair between pH value and the detected value of EC value and the setting value of controller of interior rich water
Permitted deviation range.
Irrigation control system PLC irrigation control cabinet 16 selects Siemens's S1200 series to control
Cabinet, touch screen 17 selects prestige synthetic fibre (MT8100) series, by the button on touch screen 17
Realizing the digital output modul irrigated, Fuji FNRO series selected by converter 21, detects mould
Block includes pH value and EC value sensor.
Irrigation control mode is divided into and controlling manually and automatically controlling at regular time and quantity.Filling
Irrigating in district, often equipped with an electromagnetic valve 18 on the branch road of group drip irrigation zone, each branch road is in parallel closing
System.When can realize automatically controlling by programming, when certain crops reach to need irrigation
During the time, open the electromagnetic valve controlled on this group branch road the most on time.Raw water pump electrifying startup,
Water-injection irrigation in main line.Former water in simultaneously detecting main line by turbine flowmeter 8
Instantaneous delivery, thus can calculate the former water yield used by irrigation according to irrigation time.
PLC can calculate according to the nutrient solution concentration needed for farming growth and the injection rate of former water
The injection rate of nutritional solution, injects nutritional solution, thus by controlling dosing pump in main line
Achieve automatically controlling of the Fertigation to crops.Both can be with each electromagnetic valve during irrigation
18 irrigate successively, it is also possible to irrigate fully open for electromagnetic valve 18 simultaneously.No matter which kind of uses
Irrigation method, as long as at the end of Guan Gaiing, first closes raw water pump 3, turns off electromagnetic valve 18.
PLC irrigation control cabinet 16 controls dosing pump by converter 21, is irrigated by PLC
Switch board 16 it is achieved that 1, control irrigation time；2, two kinds of nutritional solutions of mix and blend；
3, realize self-timing quantitatively to complete to irrigate, be at best able to realize 12 plans, it is possible to from
The plan group number used is needed by combination；4,12 groups of electromagnetic valves can be controlled simultaneously, and right
Each electromagnetic valve can individually enter the setting of irrigation time and Application Ratio；5, system has
Converter is reported to the police, water flow switch is reported to the police and crosses the function that stream is reported to the police；6, this fortune it is capable of
The inquiry of historical data of row.
System is capable of at most running 12 groups of plans.The plan that can set the most in the works is opened
The time begun and duration, it is possible to the selected nutritional solution needs needing to add control
The electromagnetic valve numbering that dosing pump numbering and needs are opened.And can to each electromagnetic valve and
Dosing pump is separately provided.
The Main Function of mixing pump part is stirring rich water mixed liquor so that it is more uniform.Cause
This needs according to practical situation, carries out manually opened.When needs are stirred, manually open
Opening, mixing pump will be automatically stopped, if run duration has special circumstances after running 1 hour
Or meet needs, can hand brake at any time.Timing controlled: mixing pump is from startup
Being automatically stopped after bringing into operation 1 hour, it is real that this part needs the intervalometer using in system
Existing.Non-follow control: if midway needs to stop, then have and switch off accordingly so that stir
Mix pump to stop.As shown in Figure 4.
Phase sequence is reported to the police: phase sequence alarm portion is to use phase sequence relay, under normal circumstances, protects
Protecting device and connect normally closed electric shock, in the conduction state, after phase sequence is made mistakes, phase sequence relay is automatic
Receiving normally opened electric shock, be off, at this moment PLC just can detect that this changes, thus
Generation phase sequence is reported to the police；
Raw water pump is crossed stream and is reported to the police: raw water pump is crossed stream warning and relied primarily on thermorelay and realize,
When current is excessive, bigger heat will be produced, when heat reaches to a certain degree, continue
Electrical equipment disconnects, thus creates stream and report to the police, and is also protected raw water pump.
Converter is crossed stream and is reported to the police: when the electric current flowing through converter exceedes rated current 10%,
It was considered as stream, then can be become normally opened by normally closed by the switch in the middle of converter with PLC, thus
Created stream alarm signal.
Raw water pump water flow switch is reported to the police: in internal system, can enter the instantaneous delivery of raw water pump
One preliminary surveying of row, if the umber of pulse of instantaneous delivery is less than certain value in 3-5s,
Then think that raw water pump does not has current, water flow alarm will be produced.
Embodiment
