Wine bottle liquid level detection system and method suitable for wine foam left in bottle bodies

Abstract

The invention discloses a wine bottle liquid level detection system suitable for wine foam left in bottle bodies. The wine bottle liquid level detection system comprises a conveying device, a positiondetecting device, a shooting device, a removing device and an image control processor. The image control processor receives triggering signals and sends shooting instructions to the shooting device.The shooting device conducts shooting, and sends a shot image to the image control processor. The image processor judges whether the liquid level of wine bottles is qualified or not, and if the liquidlevel of the wine bottles is disqualified, a removing instruction is sent to the removing device, and the removing device removes the wine bottles with the disqualified liquid level. The image processor is utilized for detecting whether the position of the boundary of the wine liquid and the wine foam is qualified or not so as to judge whether the liquid level of beer is qualified or not. Due tothe fact that the color difference between the foam and the wine liquid is very large, the boundary between the foam and the wine liquid can be distinguished through the ordinary image, the shooting device only needs to achieve the shooting function, influences on the detection result due to the uneven thickness of the wine bottles are avoided, and the detection result is more accurate.

Description

technical field [0001] The invention belongs to the technical field of liquid level detection, and in particular relates to a wine bottle liquid level detection system and detection method suitable for wine foam remaining in the bottle body. Background technique [0002] In the field of beer production, a liquid level detector with an X-ray detection device is generally used to detect whether the liquid level of the wine in the beer bottle is qualified. The principle is: the transmitting end sends out X-rays, and the X-rays penetrate the bottle and are received by the receiving end. The glass on the wall of the bottle and the liquid in the bottle absorb part of the rays, which weakens the intensity of the rays, and the rays received by the receiving end pass through. The calculation automatically converts a strength value, and compares this value with the critical parameter value to judge whether the liquid level of the wine in the bottle is qualified. In use, it is found t...

Problems solved by technology

Both of the above two methods require X-rays and visible light sources to pass through the wine bottle, which cannot avoid the influence of the uneven thickness of the bottle wall glass on the test results, making the final test results inaccurate
