Modular detection device and related method for odor recognition

Abstract

The invention discloses a modular detection device for smell identification and a related method. The related device includes: an interactive block arranged from top to bottom and electrically connected, several replaceable slave modules, and a main module; wherein: the interactive block Contains a liquid crystal display module for displaying information during the odor identification process; each slave module includes: sensor array and its power supply and acquisition circuit, used to obtain the response signal of the target gas; the main module, for feature extraction of the response signal And match with the odor information library to determine the type of target gas. The above solution can realize different functions through the replacement and combination of different slave modules, and can well solve the problem of complex odor types and changeable application scenarios in the field of odor recognition.

Description

technical field [0001] The invention relates to the field of machine olfaction, in particular to a modular detection device for odor recognition and related methods. Background technique [0002] Smell is an important part of human senses. At present, a large number of detection solutions based on machine olfactory technology are used in industrial production, food safety, hazardous gas detection, and medical aided diagnosis. [0003] The application in the field of odor detection is complex and the versatility is poor. For each recognition scenario, a corresponding odor recognition device needs to be customized and opened, which greatly increases the development cost. [0004] At present, most odor recognition devices are composed of three parts: sensor array, acquisition and conditioning circuit, and recognition algorithm. The core of the hardware part is the sensor array and detection module. Different sensor arrays need to be adapted according to different detection tar...
