Portable detection equipment and detection method for quickly detecting internal quality of fruit

Abstract

The invention discloses portable detection equipment and a detection method for quickly detecting internal quality of fruit. The portable detection equipment comprises a light source, a detector assembly, a main control circuit board assembly, an outer casing, a data line, a power supply module and display equipment, wherein Bluetooth communication is realized between a Bluetooth chip on the main control circuit board assembly and the display equipment. The detection method comprises the following steps of enabling the portable detection equipment to perform spectrum collection on a fruit sample; measuring sugar degree and acid degree of the fruit sample; building a predicting model for the sugar degree of the fruit; building a predicting model for the acid degree of the fruit; collecting the spectrum information of the to-be-detected fruit, and substituting into the predicting model, so as to obtain the predicting values of the sugar degree and the acid degree of the to-be-detected fruit. The portable detection equipment has the advantages that the size is small, the portable carrying function is realized, the charging function is realized, and the endurance ability is strong; compared with the traditional destructive detection method for detecting the destroy of sugar degree and acid degree of the fruit, the two indexes of the sugar degree and the acid degree of the fruit can be detected in a non-destructive way in real time; multiple types of fruits can be detected.

Description

Technical field: [0001] The invention belongs to the technical field of fruit detection, and in particular relates to a portable detection device and a detection method for quickly detecting the internal quality of fruits. Background technique: [0002] The fruit industry is of great significance in my country's national economic life, and the quality of fruit is directly related to everyone's daily life. At present, the commercialization level of fruit in our country is still low, and the quality of fruit is uneven, so there is a great need for convenient and convenient fruit detection and grading technology. The sugar acidity of fruit can represent the quality of fruit to a certain extent. At present, the detection of fruit sugar acidity mainly relies on damage detection, that is, the sugar content and pH value of the fruit are detected by squeezing the fruit juice. This method needs to destroy fruit, can only carry out random inspection for the detection of fruit quality...

AI Technical Summary

Problems solved by technology

However, the current near-infrared detection equipment requires an external power supply, cannot be carried around, and has limited application scenarios

Moreover, near-infrared spectroscopy has only been initially used for the detection of sugar and acidity in a few types of fruits
