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 remaining in the bottle body, comprising a transmission device, a position detection device, a photographing device, a rejecting device and an image control processor. The image control processor receives the trigger signal and sends a photographing instruction to the photographing device, the photographing device takes a photograph and sends the captured image to the image control processor, and the image processor judges whether the liquid level of the wine bottle is qualified, if not If it is qualified, send a rejection instruction to the rejecting device, and the rejecting device will reject the wine bottles with unqualified liquid level. The present invention uses an image processor to detect whether the position of the boundary line between the wine liquid and the wine foam is qualified to judge whether the liquid level of the beer is qualified. Since the colors of the foam and the wine liquid are very different, the separation of the two can be distinguished through an ordinary image. Therefore, the camera device only needs to realize the camera function, thus avoiding the influence of the uneven thickness of the wine bottle on the detection results, making the detection results 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
