The composition schematic diagram that is illustrated in figure 2 this utility model system control box, is provided with the elements such as microprocessor, man machine interface, velocity sensor, flow transducer, electric quantity detection apparatus, power adjusting section, alarm device in system control box 7.Microprocessor is core processor, it is the control unit of whole system, what this utility model adopted is Japanese Omron CP1H Programmable Logic Controller, traffic control, fault detect, communication management, the system control of the system of being responsible for, can be accurately information transmissions such as flow, speed, electric weight to touch screen, by man machine interface, show.Man machine interface is touch display screen, shows in real time the information such as present speed, flow, electric weight, warning, can directly set the size of flow, formulation rate.Velocity sensor is for detection of the speed of travel of pesticide applicator, and the signal recording is passed to microprocessor, and microprocessor carries out real-time adjust flux size according to the size of present speed.What this utility model adopted is hall speed sensor, is a kind of magnetoelectric transducer based on Hall effect, the signal recording can be passed to PLC, and PLC carrys out real-time adjust flux size according to present speed size.Velocity sensor is fixed in pesticide applicator frame, is connected by cable with the PLC of control chamber inside, and the rotating speed that is fixed on the measure speed gears on driving wheel turning cylinder by detection records the speed of travel of pesticide applicator.Flow transducer is for detection of the size of pipeline herb liquid flow, and converts medicinal liquid flow to standard analog signal and pass to microprocessor.What this utility model adopted is turbine flowmeter, for medicinal liquid real-time traffic being converted to standard analog amount signal, passes to PLC, and PLC reads data on flows and shows by man machine interface by processing.The dump energy of electric quantity detection apparatus Real-Time Monitoring electric supply installation gives the alarm when electric weight is not enough.Man machine interface shows in real time the information such as the current pesticide applicator speed of travel, medicinal liquid flow, formulation rate, electric weight, warning, and can directly set the parameters such as the size of formulation rate and flow.Power adjusting section regulates the input power of dispenser pump according to the control signal of microprocessor output, and then realizes the function of adjust flux.During the abnormal conditions such as alarm device is too small for dispenser flow system flow, medicinal liquid is not enough, electric weight is not enough, send information warning.Whole control system provides electric power support by 12V accumulator, because soil sterilants generally all has stronger corrosivity, therefore in the present embodiment, all pipelines adopt interior polishing 316L stainless steel tube or polyfluortetraethylene pipe, joint all adopts swagelok double card bell and spigot joint, good seal performance, guarantees pipeline air-tightness.
This utility model soil disinfecting device, when to disinfecting soil dispenser, mainly contains following steps: first, before dispenser, set dispenser total amount and spraying area in system control box, obtain unit are formulation rate; Secondly, adopt automatic dispenser pattern to carry out dispenser, by flow transducer and the actual formulation rate of velocity sensor unit of account area; Again, when detecting the actual formulation rate of unit are, system while not mating, automatically adjusts dispenser flow with default; Finally, when pesticide applicator stops walking, dispenser pump quits work.
The control system of this utility model dispenser system as shown in Figure 3.System control target is that the speed of travel of no matter pesticide applicator is constant or changes, and system automatically makes actual formulation rate and sets formulation rate and be substantially consistent.Actual what carry out flow control comparison is the formulation rate of unit are, and its unit is g/m
2, and the unit of the formulation rate that flow transducer records is L/min, and the real-time traffic that therefore must record according to the speed of travel of locomotive, fabric width and flow transducer calculates the real-time formulation rate of unit are, and its computational methods are as follows:
It is as follows that this utility model is realized its computational methods according to pesticide applicator speed of travel flow automatic regulation:
First, need to the sterilize area M in plot of setting, unit is m
2; Dispenser total amount G, unit is g; The automatic unit of account area of PLC formulation rate A, unit is g/m
2; A=M/G.
Secondly, the volume flow Q L of flow transducer Real-Time Monitoring pipeline herb liquid, unit is L/s; According to the density p of different medicaments, unit is g/cm
3; Calculate its mass flow Q, unit is g/s; Q=ρ × QL × 1000.
Again, velocity sensor Real-Time Monitoring pesticide applicator speed of travel V, the m/s of unit; N is the rotate a circle pulse number of velocity sensor output of driving wheel, and n is the pulse number that each second, PLC received, the unit of r is m, and r is driving wheel radius; V=(2 π rn)/N.
Finally, set dispenser fabric width W value, the unit of W is m, and W is generally a definite value, relevant to medicament and formulation rate; By W, V, Q, can calculate the real-time formulation rate A1 of pesticide applicator unit are, the g/m of unit
2; A1=(Q × T)/(W × V × T)=Q/ (W × V).
Microprocessor is that PLC compares the relation between A1 and A, export a control signal, control signal is controlled the rotating speed of dosing pump by the size of regulating power parts output voltage, thereby controls the flow of dosing pump, thereby realizes the big or small object that changes formulation rate according to flow velocity.
As shown in Figure 4, velocity process module and flow processing module calculate the flow of the application equipment speed of travel and pesticide applicator to this utility model control system program circuit by formula by enumerator recording impulse number; Touch screen processing module is man machine interface, comprises input and the demonstration of parameter preset; Actual value and setting value comparison module, comprise the calculating of actual formulation rate A1 and the comparison of default formulation rate A; Power adjustment process module, according to the I/O output valve of PLC, changes the input power of dispenser pump, thereby realizes the function that regulates dispenser flow according to the locomotive speed of travel.
Be illustrated in figure 5 the structure diagram of this utility model system control box.Wherein 16 is case lid, can be pinned by active lock 17, and case lid mosaic glass plate, can watch the content showing in man machine interface 18 by glass plate.Man machine interface 18 shows the information such as present speed, flow, electric weight, warning in real time, and can directly carry out big or small setting and the adjusting of flow, formulation rate.Man machine interface 18 sides are shift knob 19 and alarm 20.Because soil disinfection medicament has stronger corrosivity conventionally, therefore electronic component and drug delivery system must be kept apart, prevent leakage of medicament etching electronic part, system control box 7 is divided into independently electric panel room 21 and Teat pipette chamber 22.The electronic accessory parts such as the interior installation of electric panel room 21 PLC, accumulator.The medicament circulation spare and accessory parts such as dispenser pump, flow transducer and loading pipeline are installed in Teat pipette chamber 22.Because soil disinfection environment is severe, often carry out out of doors and under more dirty and messy environment, and mainly rely on hand tractor that traction power is provided, shake byer force, therefore control chamber will be carried out dustproof, waterproof and shockproof processing.
Its work process is: velocity sensor 10 feeds back to the speed of measure speed gears 11 in system control box 7, and system control box 7 carries out by drain pipe 6, disinfectant solution being transported on dispenser cutter 13 after flow rate calculation, and dispenser cutter 13 is to disinfecting soil processing.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
