Description
Art
The present invention relates to a kind of corn castration machine emasculation operation-control system, it is adaptable to mechanical field.
Background technology
Corn emasculation directly affects the quality of corn seed as the key link of corn seed producing.Traditional manual detasseling poor working environment, labour intensity is big, inefficiency, operation quality it is difficult to ensure that, mechanical emasculation efficiency and operation quality are higher, there is the trend gradually instead of artificial emasculation.In agriculture developed country, corn castration machine has been widely used, such as the emasculation spraying machine of Bourgoin companies of France, the emasculation machine of Hagie companies of the U.S. 204, U.S.'s Big John companies PDF752D emasculation machines etc., its technology maturation, and warp-wise utilizes the higher development of machine vision mapping maize fringe height.
It is still based on artificial in Chinese maize emasculation, a small amount of emasculation machine is also to rely on import, the development of emasculation machine is still in the starting stage, and focus primarily upon hydraulic system, emasculation control system as emasculation machine core, the no automatically and precisely emasculation operation of emasculation function directly is decide, its development is even more far behind developed country, and this directly governs the development of Chinese emasculation machine.
The content of the invention
The present invention proposes a kind of corn castration machine emasculation operation-control system, and system can realize manually adjusting for emasculation mechanism height by push-botton operation, also can be by the collection of corncob elevation information, and the adjust automatically of emasculation mechanism height is realized in the derivation of control algolithm.
The technical solution adopted in the present invention is.
The emasculation operation-control system is mainly made up of master control borad, control panel, display screen.
The master control borad completes sensor signal reading, voltage x current protection and pulsewidth modulation mainly including ATmega128 processors, photoelectric sensor, the driving of multi-channel proportional valve, current protection, voltage protection, power supply, serial ports and module etc. debugging（Pulse width modulation, PWM）The output of control signal.ATmega128 chips are high-performance, the AVR8 bit microprocessors of low-power consumption, and its flash storage for being internally integrated 128kB is exported with advanced risc architecture and multi-channel PWM.
The control system uses a pair of 42GRU-9200TTL models（NPN types）Photoelectric sensor, blocks switching signal that upper and lower photoelectric sensor produces to judge the height of corncob by corn, and driving voltage and electric current are gathered using MAX4372T chips, and is compared with normal value, to prevent voltage or electric current excessive and damage master control borad.Circuit drives proportioning valve using power field effect pipe IRF4905；Serial communication is completed using MAX232 chips.Power module provides the 3.3 and 12V power supplys of stabilization for whole controller.
The emasculation control system reads the height of corncob by the photoelectric sensor that about a pair are installed side by side, and elevation information is transmitted to controller, controller is processed information according to control algolithm, then the valve element aperture of proportioning valve is controlled by PWM signals according to result, complete to hydraulic cylinder speed and the precise control of displacement, Hydraulic Cylinder parallel four-bar linkage completes the adjustment of emasculation mechanism height.
The control system is divided into manually and automatically pattern, and under manual mode, system is by the output of the pwm signal of button control dutycycle B1 sizes adjusting the height of emasculation mechanism；Under automatic mode, according to the height of sensor signal adjust automatically emasculation mechanism.Initialized after system electrification, initialize the frequency of each pwm signal and close all PWM outputs, initialized serial ports.
After initialization is completed, parameter setting is carried out, acquisition systematic parameter is recalculated if parameter is different from last time and is shown.When emasculation operation, system is switched to automatic mode, system can read all photo-sensor signals continuous y times, interval time t1 is read every time, count number of times that upper and lower photoelectric sensor is blocked and be stored as xth group data, then the 1st group of data of storage make the lifting decision-making of emasculation mechanism according to before.
System stops output according to the pwm signal of decision-making output duty cycle B2 sizes after the t2 times.When the only continuous z lifting result of decision is to rise, system can just export rising pwm signal.PWM outputs are deleted the 1st group of data and other data storage locations move forward successively after stopping, vacating xth group Data Position.Then detection voltage and electric current, if there is exception to shut down procedure operation, and alert immediately, enter next circulation if normal.
The beneficial effects of the invention are as follows：System that employs multiple sensor signal is read, result is stored and time delay taking-up and continuous several times rise the control algolithm of judgement, and through overtesting and the parameter of calculating determination system, increased the precision of emasculation mechanism kinematic control.
