Pork freshness intelligent detection device

Abstract

The invention discloses an intelligent pork freshness detecting device, and comprises a gas-collecting module (1), an image collecting module (2), a neural network module (3) and a computer (4), which are connected mutually through a leading wire. The gas-collecting module (1) collects a released ammonia gas (NH 3 ) and a hydrosulfuric acid gas (H 2 S) during the metamorphic process of the pork; the image collecting module (2) collects a diagnostic information of a relative gray-scale value (H, S, I) of a diagnostic wavelength of a specific element during the metamorphic process of the pork; H, S, and I are respectively a brightness, a chrominance and a saturation; the released ammonia gas and the hydrosulfuric acid during the metamorphic process of the pork, and the relative gray-scale value of H, S and I are inputted in the neural network module (3). The grade of the freshness of the pork is gained through the interfusion of a plurality of data, and can be displayed on the screen of the PC computer (4). The invention has the advantages that the fast detecting on site can be achieved, and the freshness of the pork can be identified expediently, quickly and effectively.

Description

technical field [0001] The present invention relates to a kind of testing and gas sensing technology using optical means, specifically using photoelectric micro testing processing technology and gas detection technology to detect the freshness of pork. The relative effect of the element's characteristic wavelengths on the properties of the tested material varies with the system, ie the G01N21 / 31 field. Background technique [0002] At present, the testing techniques for pork freshness include sensory testing, physical and chemical testing, etc. Sensory testing technology has high requirements on the ability of inspectors, and only those who have undergone systematic training and long-term practice can be competent. Physical and chemical inspection technology requires a series of equipment and devices to complete, the process is complicated, the detection time is long, and the equipment is complicated. Therefore, there is an urgent need for a fast, effective and scientific ...

Problems solved by technology

Its shortcoming is: because different parts of the meat have different densities, and at the same time, the degree of change in the corruption is also different. Therefore, three beams of light with three wavelengths of known intensity are used to enter the interior of the meat from the surface of the meat. The light intensity of different wavelengths scattered from the meat is detected in two different annular areas on the surface of the meat, and the freshness of the meat cannot be detected completely and accurately.
