Fertilizer apparatus is driven to be operated, performance falls behind, it is impossible to meet production needs.And the variable fertilizer applicator price released in recent years is held high
Expensive, operating difficulties the shortcomings of debugging maintenance inconvenience, is not suitable for China's Agriculture Present Situation, unsuitable spread.
The content of the invention
For above-mentioned problems of the prior art and defect, seeder is based on it is an object of the invention to provide one kind
Variable fertilization control system, the control system powered and all-electric fertilising process using automobile storage battery, simplifies complexity
Mechanical transmission mechanism, the fertilizer apparatus that can completely replace traditional Purely mechanical to drive.
Realize that foregoing invention purpose technical scheme is a kind of variable fertilization control system based on seeder, including monolithic
Machine, stepper motor, fertilizer apparatus, battery, output output equipment, it is characterised in that by exporting output equipment to single-chip microcomputer
One unit area fertilising value of setting, described single-chip microcomputer gathers fertilizer apparatus rotating speed and equipment advance speed by velocity sensor
Degree, and the line-spacing of fertilizer apparatus according to setting, fertilizer apparatus number and every defertilizing amount that turns calculate actual dose per minute,
Compared with setting value, with automatic control algorithm, the rotating speed of real-time regulation stepper motor makes actual dose and set-point phase
Unanimously, and by result output output equipment is sent to；Described battery is used to be powered to single-chip microcomputer, stepper motor.
Variable fertilization control system of the present invention compared with prior art, has the advantages that：
1）Variable fertilization control system of the present invention using single-chip microcomputer as control core, with automatic control algorithm, as needed
Regulated fertilization amount, realizes variable fertilization, effectively improves the utilization rate of chemical fertilizer, reduce because fertilizer application is improper and caused by environment it is dirty
Dye and food-safety problem.
2）Variable fertilization control system of the present invention can be used with middle-size and small-size tractor, be powered using automobile storage battery,
With good versatility.
3）The all-electric complicated mechanical transmission mechanism of process simplification that applies fertilizer of variable fertilization control system of the present invention, reduces
Design cost and operation maintenance difficulty, save substantial amounts of manpower and materials.
Brief description of the drawings
Fig. 1 is the control principle drawing of variable fertilization control system of the present invention based on seeder；
Fig. 2 is the circuit diagram of variable fertilization control system of the present invention based on seeder.
Specific embodiment
Fig. 1 be the present invention based on seeder variable fertilization control system control principle drawing, including single-chip microcomputer, stepping electricity
Machine, fertilizer apparatus, battery, output output equipment, it is characterised in that set a list to single-chip microcomputer by exporting output equipment
Plane accumulates fertilising value, described single-chip microcomputer by velocity sensor collection fertilizer apparatus rotating speed and equipment pace, and according to setting
The line-spacing of fixed fertilizer apparatus, fertilizer apparatus number and every defertilizing amount that turns calculate actual dose per minute, with setting value phase
Compare, with automatic control algorithm, the rotating speed of real-time regulation stepper motor makes actual dose and set-point consistent, and will
Result sends output output equipment to；Described battery is used to be powered to single-chip microcomputer, stepper motor.
The operation principle of variable fertilization control system of the present invention based on seeder：
The fertilizer expelling shaft of the variable fertilization control system is connected with stepper motor output shaft.As needed, by adjusting stepper motor
Rotating speed controls the rotating speed of fertilizer expelling shaft, so as to change defertilizing amount, realizes variable fertilization.
It is control core that the variable fertilization control system uses single-chip microcomputer, using the method for artificial given dose, that is, is set
Determine unit area dose, single-chip microcomputer by gathering fertilizer apparatus rotating speed and equipment pace, and according to the fertilizer apparatus of setting
Line-spacing, fertilizer apparatus number and every defertilizing amount that turns calculate actual dose per minute.Compared with setting value, with automatic
Control algolithm, the rotating speed of real-time regulation stepper motor makes actual dose and set-point consistent.Using single-chip microcomputer to stepping electricity
Machine rotating speed carries out real-time regulation control, so as to realize needing to carry out variable fertilization according to different.
The variable fertilization control system needs real-time testing fertilizer applicator gait of march with the two speed amounts of fertilising rotating speed, profit
Photoelectric velocity measurement principle is used, two coding disks that test the speed are respectively mounted on fertilizer applicator land axle and fertilizer applicator axle, coding disk rotates meeting
The light that constantly triggering infrared transmitting tube is launched, and then level translation is produced at infrared receiver end, by the counting of single-chip microcomputer
Device calculates interruption times of two axles in the unit interval respectively, is then converted to required speed amount.Wherein coding disk uses multiple-grid
Lattice mode, such that it is able to improve certainty of measurement.
Fig. 2 is the circuit diagram of variable fertilization control system of the present invention based on seeder, and system is made from LCD1602 liquid crystal
It is information display interface, it uses parallel communications, communication efficiency can be improved.Information wherein to display includes fertilizer applicator row
Enter speed, the rotating speed of fertilization axle, total fertilization amount and unit area dose etc..
The variable fertilization control system can be entered by the keyboard using the matrix keyboard of 4*4 to unit area dose
Row is set and the manual control to system.
The variable fertilization control system is realized to different crops and difference with single-chip microcomputer STC89C51 as control core
Environment is applied fertilizer on demand, is effectively improved the utilization rate of chemical fertilizer, alleviates environmental pressure, the problems such as reduce food security.
In actual applications, apparatus system stabilization, control is accurate, simple to operate, saves a large amount of human resources, can substitute completely existing
The fertilizer apparatus for having Purely mechanical to drive, while reducing design cost, Operation and maintenance difficulty, meets China's Agriculture Present Situation,
Be conducive to the sustainable development of China's agricultural, suitably in China's spread.
