Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of detection, and particularly relates to a visual image and photoelectric data correlation detection device and method for composite cigarettes. BACKGROUND

[0002] The ZB25 / ZB45 series medium-speed packaging unit is a mainstream model in domestic cigarette factories. In order to ensure the quality of the cigarettes, a cigarette detector needs to be installed on the packaging line to detect the filling condition of the single cigarette in the cigarette packet (empty-end detection) and the integrity of the entire cigarette packet (missing cigarette and missing end detection). At present, there are mainly two detection methods for empty-end detection on the market, namely, photoelectric detection and visual detection. The photoelectric detection device has poor human-computer interaction and simple statistical data. The visual detection device has good human-computer interaction and powerful statistical data function, and can provide user traceability for defect images. However, since the camera for empty-end detection has a fixed shooting angle, the shooting image has an unobvious empty-end effect, which may cause a missed detection.

[0003] Therefore, a new generation of composite cigarette detector is developed by combining the photoelectric and visual detection methods. The detector scans and collects photoelectric data on the tobacco end face in the dynamic interval, and takes a photo to collect visual images of the tobacco end face in the static position. The photoelectric detection and image data processing technologies are used to process the detection data, and a rejection signal is sent to the packaging unit control system according to the detection result. When a defective cigarette packet is detected, the photoelectric and visual detection data of the defective cigarette packet are stored in correlation, so that the user can view and feedback adjust the detection parameters according to the detection result. SUMMARY

[0037] Figure 3 This is a flowchart of the method of the present invention. Detailed Implementation

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0039] This invention proposes a method for visual image and photoelectric data association retrieval of composite cigarettes, the process of which is as follows: Figure 3 As shown, the process first reads the start marker of the cycle return signal from the lower-level machine, then fills the photoelectric data buffer, visual image, and corresponding detection information into the photoelectric data buffer and visual image buffer, respectively. Next, it reads the end marker of the cycle return signal from the lower-level machine, determines whether the photoelectric data or visual image has been filled into the buffer within the cycle, and fuses the photoelectric and visual detection results based on the filling status to comprehensively judge the detection result of the current cigarette pack. Based on the detection results, it stores the number of empty cigarette packs detected, the number of defects, and the photoelectric data and visual images of defects. The user can view the visual image and corresponding photoelectric data of the defective cigarette pack on the human-machine interface, ultimately realizing the association and retrieval of visual images and photoelectric data for composite cigarette detection. The specific process is as follows:

[0040] During actual testing, when the start of the testing cycle arrives, the detector's microcontroller sends a cycle signal to begin marking, and the detector's host computer reads the cycle signal to begin marking. The tobacco shreds slide past the phototube, and the phototube forms a voltage data pattern based on the phase data collected. Figure 1 The photoelectric data curve is processed by the detector's host computer, which initiates a photoelectric data processing thread to process the data and store the results in the photoelectric data buffer. The tobacco shreds pass through a tobacco camera, which then captures images of the tobacco shreds. Figure 2 The visual image in the detector is processed by the host computer of the detector, which starts an image processing thread to process the visual image data and stores the processed result in the visual image buffer.

[0041] The microcontroller sends a periodic signal to mark the end of the cycle, and the detector's host computer receives the periodic signal. The host computer searches the photoelectric data buffer and the visual image buffer. If both photoelectric data and visual image data are lost, a blank detection fault is marked; otherwise, the blank detection count is incremented by 1. With the blank detection count incremented, the system determines whether the detected tobacco has defects based on the photoelectric data and visual image detection results. If defects are found, the blank defect count is incremented by 1, and either the photoelectric data or the visual image is saved, with missing photoelectric data or visual images marked as missing. After successful saving, the corresponding photoelectric data and visual image buffers are cleared. This completes the associated storage of visual images and photoelectric data for composite cigarette detection.

[0042] The user views the visual image of the defective cigarette packet and the corresponding photoelectric data on the human-computer interaction interface, and finally realizes the associated retrieval of the photoelectric data and the visual image of the composite cigarette detection.

[0043] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present application should also be within the scope of the present application.
