A Harbin bacon detecting device and method based on a visual gas sensing array

The invention discloses a Harbin bacon detecting device and method based on a visual gas sensing array, which relates to the technical field of detecting the quality of agricultural and livestock products. The invention provides a detection system and method for harvest bacon based on a visual gas sensor array, aiming at the problem of lack of harvest detection technology in the current bacon storage process, which has the characteristics of fast, lossless and visualization, and can realize the rapid detection of harvest sample during the bacon storage. In this method, the characteristic volatile gases of Harbin bacon were detected and the corresponding gas sensing materials were screened, and the gas sensing array was constructed. The image of the sensor array before and after reaction isacquired by the image acquisition device, and the gray level average of each channel in the sensor array before and after reaction is extracted to be the odor characteristic matrix of the measured sample.
