Description
Technical field
The present invention relates to a kind of cereal look and select control system.
Background technology
Grain color selector is according to the difference of cereal optical characteristics, utilize photoelectric sense technology, digital image processing techniques and Control Technique of Microcomputer, by a kind of photoelectricity non-destructive detecting device that color there are differences, surface exists defect or inner rotten bad material sorts out from large batch materials.It distinguishes, sorts heterochromatic grain and impurity wherein by the color of product, and particularly, in the case of granularity, the density etc. of defective grain and qualified grain are all quite similar, look selects and becomes unique method for separating.
Color selector has fully utilized the new technology in the subjects such as contemporary optics, photoelectric sensing, image processing, Electronic Control and computer utility, is the typical new high-tech product of light, mechanical, electrical, gas one.At present the domestic independent research and development capacity of this technology generally a little less than, gordian technique and components and parts dependence on import, research and development and the application of the technology such as photoelectric sensing, image processing, signal processing and high speed jet system still belong to the primary stage, stability, reliability and the long-term continuous operation life-span of electric-control system are not high, and product detects examination means and falls behind.Meanwhile, apply this technology grain selection technical market potential of demand huge.So the Exploitation Depth of this technology and range are very large, the having a extensive future of technological development and innovation.
A lot of parameter indexs (such as flow, chute elevation angle etc.) of existing grain color selector need field engineer's experience to adjust, existing many control system are that the parameter index that these are regulated pre-deposits in the database of system, and then recall setup parameter in system database according to the quality of material to be selected and offer color selector and use.The weak point of this control mode is the experience that depends on expert, control that can not be real-time and adjustment; The shortcoming of this control mode is to rely on expert's look to select experience, control and adjustment that can not be real-time to each service part of color selector, therefore can affect stability and the reliability of color selector, and then make to weigh two large indexs of color selector serviceability: look selects that rate is on the low side and the rate of taking out of is higher, have specifically following some:
1, because imageing sensor resolution is not high, light source and background board angle can not Based Intelligent Control, and the look of satisfied different cereal that therefore can not intelligence selects requirement, and the evil ideas such as heterochromatic grain and small scab are difficult for selecting;
2, because can not Based Intelligent Control color selector, grain selection yields poorly, and machine volume is too large, is not easy to mobile;
3, photoelectric sensor resolution is low, and the image signal noise of collection is large, directly affects look and selects effect;
4, electronic devices and components consistance and reliability are not high, affect the stability of product.
Summary of the invention
The present invention is in order to solve above-mentioned deficiency, provides a kind of cereal look to select control system.
Above-mentioned purpose of the present invention realizes by following technical scheme: a kind of cereal look selects control system, it is characterized in that: comprise master control borad, master control borad connects man-machine interface, dsp board, motor drive plate and PLC plate, dsp board connects CCD plate and indicator board, motor drive plate connects background board system for regulating angle, PLC plate connects feeder, light source, purging system, air valve drive plate and motor drive plate, and feeder connects Vib., pneumatic actuation plate connected electromagnetic valve;
Described master control borad is the core of grain color selector control system, communicates by letter with man-machine interface by single-chip microcomputer, obtains and controls parameter, then parameter is passed to motor drive plate, PLC plate, dsp board; Master control borad is responsible for storing all programs and numerical control information, and start primary data is transmitted man-machine interface by master control borad and shown; And be responsible for storage tuning parameter, control motor drive plate, thereby control the angular setting of background board; Meanwhile, the primary data of logic control is passed to PLC plate; The signal that PLC buttress transmits according to master control borad, controls feeder start-stop; Control the start-stop of solenoid valve; Control the start-stop of purging system, reach the object of cleaning; Select requirement according to the look of different cereal, light source process is adjusted, select requirement with the look that adapts to different cereal;
Described man-machine interface is inputoutput unit, is responsible for receiving the input of instruction, and result is exported;
The picture signal that described dsp board transmits CCD plate carries out passing to master control borad after signal processing, pass to man-machine interface display waveform by master control borad, DSP controls indicator board, indicator signal processing element duty, the control Data Control air valve drive plate that PLC buttress transmits according to master control borad, drive solenoid valve by air valve drive plate, heterochromatic grain is rejected;
Described feeder, carries out the control signal that PLC plate transmits, and drives Vib., regulates feeding capacity size;
Described motor drive plate drives background board regulating system, adjusts the angle of background board, to adapt to different materials;
Described air valve drive plate is carried out the control signal that PLC plate transmits, and drives solenoid valve, and waste material is rejected.
The present invention's advantage is compared with prior art: cereal look of the present invention selected control system stability processed is reliable, flexibly economical, by the expansion of the single-chip microcomputer output port to master control borad, form a small and exquisite complete control system, realize real-time control and adjustment to each service part, improve look and select rate, reduce the rate of taking out of; And can be transplanted to easily in other system.
