Description

technical field [0001] The invention belongs to an anticorrosion detection device in the process of grape transportation and storage, in particular to an LMSE-based grape deterioration monitoring instrument. Background technique [0002] At present, there have been many successful applications of smell in predicting the disease and decay of agricultural products. For example, Li Changying used an array of gas sensors to analyze the lesions of onions. Zou Xiaobo and Zhao Jiewen developed an electronic nose device that can quickly detect whether the grain is moldy. The device can quickly and accurately analyze the smell emitted by the measured grain and determine whether the measured grain is moldy. The accuracy rate of the electronic nose for the discrimination of wheat, rice and corn is greater than 80%. However, the size and power consumption of sensor arrays and analysis systems are relatively large, which are not suitable for direct use in real-time monitoring and multi...
