Abstract

The invention belongs to the technical field of food detection, and discloses an efficient and stable atomic absorption spectrometer for food detection and a control method thereof. The efficient andstable atomic absorption spectrometer for food detection comprises a food spectrum acquisition module, a spectrum image enhancement module, a food feature extraction module, a central control module,a food detection module, a food quality evaluation module, an early warning module, a data storage module and a display module. According to the invention, more accurate and comprehensive food qualityjudgment and analysis are realized through the food detection module; the weighted similarity algorithm is a quantification method, so the result output is more specific, and intuitive digital judgment is facilitated; the early warning module determines the detection result corresponding to the detection area according to the detection item type and the detection value in the detection area, thereby achieving the remote uploading of the detection data, carrying out the processing and analysis of the big data at the cloud, judging the abnormality based on the big data analysis result, and timely giving an early warning.
