6SXZ series Grains cereals color sorter



Click the middle camera gain button at the right upper corner on the interface of signal settings, the system will automatically skip to the interface of camera gain. The main purpose of the interface of camera gain is to adjust the gain of cameras. The following is the general principle for adjusting camera gain: In the single selection of minimum value, the signal of normal material can be varied between 192 and 244. In the simultaneous usage of minimum value and maximum value, the signal of normal material can be varied between 128 and 160. Therefore, a larger dynamic range can be ensured (Note, it is signal of normal material, rather than background signal). Each trough is equipped with two cameras (including a front view camera and a rear view camera). When the camera gain is adjusted, the front view camera and the rear view camera are separately adjusted.



4.2.9 Optical Calibration Click the rightmost optical calibration button at the left upper corner on the interface of signal settings, the system will automatically skip to the optical calibration interface. The optical calibration interface is mainly used for completing the calibration of optical systems, monitoring the adjustment of camera positions and monitoring the condition of data paths.



Figure 4-11 optical calibration interface



Clicking the optical calibration button, the user can perform optical calibration on each trough. Each trough needs independent calibration. The following is the steps of calibration: firstly, put a white balance target on the corresponding channel; then, observe whether signals are normal through the waveform window; signals at all positions on the channel can be observed through mobile selection; if signals have no outstanding bright or dark points and generally present the shape of flat bell, the signals are abnormal, the user can click the calibration button to perform calibration (front and rear views can be simultaneously calibrated, so independent calibration is unnecessary). Monitoring of camera position adjustment is to assist the adjustment of camera positions. Firstly, select the right middle camera adjustment, and put on the calibration target; at the moment, observe whether the bell shape of signal waveform is sharp enough, namely is close to the shape of rectangle, otherwise, it is necessary to adjust the focal length to make the waveform sharp enough; then observe whether signals of the camera overlap with corresponding standard line, if completely overlap, it means the camera position is appropriate, and the camera can be positioned. The monitoring of conditions of the data path is to check whether the data path is normal. From original data, the user can see data from cameras. From calibration data, the user can see data calibrated by the system. From test data, the user can see linear test data from cameras.

The system information interface is mainly used for reviewing the state information of the system, mainly including the communication quality, software version, information records, statistics of working frequency of spray valves, and detection information in startup. The communication quality interface shows the communication state of the system, mainly including the display board, the control board and the LED board. Communication quality is divided into a transmission part and a reception part. Under normal state, the number is 0; the larger the number is, the poorer the communication quality is. When the number is larger than 128, the communication system can only perform reception, cannot perform transmission. When the number is 255, thecommunication is completely lost.



The dialogbox for spray valve test is the first row on the ejecting valve interface. The spray valve test is mainly used for detecting whether the spray valve is normal. Click the upper part of the dialogbox for spray valve test to select trough; then, click channel n to input the position of the spray valve to be detected, and the position of the spray valve to be detected can also be adjusted by increasing and increasing buttons. Channel data indicate the position of the current tested spray valve; when the repeat button is in the repeatedly open state, the channel repeatedly tests the spray valve in the frequency of three times per second. When the high-frequency button is in the high-frequency open state, the spray valve is tested 15 times as the spray valve acts once. The auto test button is used to test spray valves of all channels of all troughs The interface for setting removal time is used to set blowing time, delay time, the starting time of spray valves, and the compound modes of valves. The delay time is the time during which the system finds the flawed material and the flawed material falls to the position of the blowing nozzle. The blowing time is how long the high-frequency gas flow sprayed out from the nozzle will last every time. The system divides the blowing time and the delay time for spot impurities and regional impurities. The starting time of the spray valve is the time taken to start the spray valve after the valve receives the instruction every time.



Click the refresh button, the user can read the communication state again.



The compound modes of valves include independent blowing, additional left blowing, additional right blowing, and both left and right blowing. Independent blowing indicates single spray valve blows; additional left blowing indicates while the current spray valve blows, one valve on the left of the spray valve also blows; additional right blowing indicates while the current valve blows, one spray valve on the right also blows; the above two modes indicate there are two spray valves spraying together; both left and right blowing indicates while the current spray valve blows, the left spray valve and the right spray valve blow together.

The feeding amount interface mainly realizes the adjustment of feeding amount, start and shutdown of the feeding machine. The adjustment range of the feeding amount is 1-99. When the feeding machine button on the toolbar shows “feeding machine shutdown”, the feeding machine will not feed materials regardless of the feeding amount of upper part and the state of the switch of the feeding machine. When the feeding machine button on the toolbar shows “feeding machine start”, the open state of the feeding machine with single channel can be controlled through the upper vibrator switch. In the dialog box of vibrator settings, for the adjustment of the vibration frequency, the vibration frequency should be consistent with the frequency marked on the vibrator, otherwise, the normal operation of the vibrator cannot be guaranteed.



4.2.16 Sensitivity interface The sensitivity interface mainly includes gray-level sensitivity interface, chroma sensitivity interface, and colordifference sensitivity interface. The user can use gray-level sensitivity interface, chroma sensitivity interface, and color-difference sensitivity interface independently or compositely.

3 Shape-selecting sensitivity interface Click the button of Shape-selecting, and directly shift to the shape-selecting sensitivity interface. At present the shape-selecting function mainly includes to choose length, area, and roughness. Using what kind of shapeselecting procedure relies on the selected materials. As shown in figure 4_28 the interface is normal standard shape-selection. Of course according to the difference of the procedure of system document you select, the shape-selecting interface is different. But the most common shape-selecting interface generally includes the option about length and area. Note: check shape option and select the shape selection file needed by color selection material at the drop-down bar of shape option when you select the shape option and allocate the scheme, and then click the application button.



Figure 4-28 Color Sensitivity Interface



Color –level sensitivity interface mainly completes the settings of chromatic parameters, majorly including the state of chromatic selection, the types of chromatic use, intensity control, and dimension settings etc. The state of chromatic selection can use or be forbidden to use foresight and backsight.The types of chromatic use needs to be done in the solute on configuration of color-selecting project, mainly including the three types, red-green chromatic aberration, red-blue chromatic aberration, and green-blue chromatic aberration. Red-green chromatic aberration is mainly applied for the flawed materials which selects the color between red and green. Red-blue chromatic aberration is mainly applied for the flawed materials which selects the color between red and blue. Green-blue chromatic aberration is mainly applied for the flawed materials which selects the color between green and blue. In generally only one type can be used to select color, and at most two types can be used to select color at the same time. As long as it is determined by the color-selecting materials, brightness limit will decide the range of color-selecting.



Picture 4_29 Shape-selecting sensitivity interface



4 Image-selecting sensitivity interface



Dimension settings mainly rely on the shapes of the materials to set corresponding data. Sensitivity of color difference is mainly used to adjust the digital increase of the red, of the green and of the blue. Color differences of the red and the green correspond to increase of red number. Color differences of the red and the blue correspond to increase of green number. Color differences of the blue and the green correspond to increase of green number. If the radio button is red, not green, which means the red one is defective material, if the radio button is green, not red, which means the green one is defective material. If the radio button is red, not blue, which means the red one is defective material, if the radio button is blue, not red, which means the blue one is defective material. If the radio button is blue, not green, which means the blue one is defective material, if the radio button is green, not blue, which means the blue one is defective material. Color differences mainly aim at the relatively less types of colors, and carry out choosing color for materials having small color differences.

The picture -selecting of sensitivity is so called chroma sensitivity. The chroma sensitivity is a color selection method of distinguishing material in HSL color space, H means hue, S means saturation, L means lightness among these. Hue reflects the color category of material, like red, yellow, green and blue, saturation means the darkness/lightness or purity of colored light presented. The higher the saturation is, the color will be more dark or pure, the smaller the saturation is, the color will be more shallow or lower for purity for the colored light with the same hue. The lightness is a feeling of brightness caused by light acting on the human's eyes.



6SXZ series Grains cereals color sorter



The button of sending threshold mainly puts HS into force by sending the threshold of HS to color selection processing board after adjusting the threshold of HS, confirming that the background is not in the scope of defective material before sending it. Or it can lead to blow the background by mouthpiece, which will affect the mouthpiece's life for long time blowing. Before adding to the rectangle, it needs to collect the image acquisition for its current color selection material, and after collecting, it needs to click “Add Rectangle ”button to realize increasing in functionality of the new rectangle. In the dialog, you can adjust the size and position of the rectangle, not only input directly data in the edit box, but also click various buttons to adjust locally. After the adjustment of the rectangle area and clicking the ensure button, the rectangle area present in the graphic display area, if you want to give up the adjustment, you could click the cancel button. When you want to adjust the existed rectangle area,you can directly input the related parameters in the input field on the right side, then click to send thresholds to ensure the effectiveness of the re-entered data. If it dose not need to modify in the current rectangle, you could add the rectangle again after deleting the current rectangle. What the type of data in the limited of brightness describes is the color which can be the standard of the bright measurement, and the system offers seven types of data resource for users selection as follows: red, green, blue, red+green, red+blue, green+blue and red+green+blue. The upper limit and lower limit of the brightness combine the eliminate outside and eliminate inside to use, during eliminating outside, the elimination which is higher than the upper limit or lower than the lower limit will be the elimination material at next time;during eliminating inside, the elimination which is lower than the upper limit or higher than the lower limit will be eliminated as the flaw material.



Figure 4-31 Shape option of sensitivity interface During showing the H_S picture, the horizontal axis stands for Hue, the vertical axis for saturation. From the picture 4-27, it can be seen that the materials of different color in the area of hue coordinate are different, by default red is at the two sides of the image, with its value of number lying in the right side of number 0 and the left side of number 360; the higher the saturation is, the color will be more vibrant and purer.



The general operation of the chromatic sensitivity: observe material→ adjust background→ add rectangle→ select color , observe the color selection effect→modify rectangle→select color again. (1) Observe material: observe material to choose certain non-defective material and the color range of the incompetent material.



The main purpose of the translation marquee of the image is to be convenient to watch the materials in the red areas, the image moves to the right 180 degrees circularly when selected, at the time the red areas are shown in the area of the center of the image, green is shown in the two ends of the image; restore to the default state when unchecked, green is shown at the center of the image, and red is shown at the two ends of the image.



(2) Adjust background: adjust background board to make background color to be the same with non-defective material color.



Select the senior after selecting interface trough, then click the enter button. There are size setting, elimination method, and parameter copy in this interface. The button of forbidden or use is to adjust conveniently, which makes the HSL threshold of foresight or backsight in the relevant troughs not working. The elimination methods include sensitivity elimination and brightness elimination, you can eliminate inner or outer and switch between HS with L and HS or L, and copy the parameters between each trough according to confirmed relevant parameters. The parameter copy reduces the readjustment times of each trough for debuggers, and the debuggers just need to fine-tune the parameter of each trough.



incompetent material.



HS and L/HS or L buttons provide the combination mode of threshold of HS and L, display of HS and L means that the HS threshold value and L threshold value are simultaneously satisfied, the materials can be regarded as the defective materials to be removed. Display of HS or L means that if HS threshold value or L threshold value are satisfied, the materials can be regarded as the defective materials to be removed. The data of trough is used to adjust the material trough which is observed and change threshold of the material trough. The data frame of impurity is used to adjust the number of data points which must meet the threshold value.
