A photoelectric detection model transfer and sharing method and an Internet of Things monitoring and evaluation system based on a cloud service are provided. The transfer and sharing method includes: invoking a temperature compensation model and a spectrum transfer model to calibrate spectrum information of agricultural product samples, and invoking a detection model to compute the calibrated spectrum information to obtain detection results of the agricultural product samples. The Internet of Things monitoring and evaluation system calibrates spectrum information by using a spectrum transfer and sharing method, invokes a detection model for computing, and returns detection results to a detection terminal in real time, thereby realizing remote monitoring and evaluation of the quality of agricultural products.

A method of preparing a nanoscaled dye@ZIF-8-based colorimetric sensor is provided, in which a ZIF-8 nanomaterial is first prepared from Zn(CHCOO)and the 2-methylimidazole, and then the ZIF-8 nanomaterial is dispersed with ethanol and mixed with a colorimetric solution. The resultant mixed solution is added with polyethylene glycol-300 and applied to a substrate to obtain the nanoscaled dye@ZIF-8-based colorimetric sensor. This application further provides an evaluation method using the nanoscaled dye@ZIF-8-based colorimetric sensor, in which a back propagation neural network is established as the food quality evaluation model to evaluate the food quality.

A method and a device for detecting plastic foreign objects with low chromaticity difference in shredded tobacco through online pulse spectral imaging are provided. The method includes three steps: negative pressure thin-layer loading of shredded tobacco, pulse line-scanning identification of shredded tobacco, and positive pressure online elimination of foreign objects. Loose shredded tobacco is formed into a fixed and continuous thin layer on a surface of a conveying cylinder under the effect of a negative pressure adsorption force. The surface of the conveying cylinder is coded by areas. An LED linear array light source containing characteristic wavelengths of plastics with low chromaticity difference emits optical pulses, and a line-scanning camera is used to obtain characteristic signals of the plastic foreign objects with low chromaticity difference efficiently in real time.

Fluorescent test paper for detecting mercury ions is firstly prepared, the fluorescent test paper including a fluorescence development area and a standard fluorescent colorimetric card. With reference to an excited color corresponding to a reference channel in the standard colorimetric card, the color corresponding to a carbon quantum dots distribution area on the fluorescent test paper is observed to check the fluorescence detection environment during detection with the fluorescent test paper. In colorimetric detection of the content of mercury ions, the concentration of Hgis detected based on an excited color, in the standard colorimetric card, that corresponds to a standard mercury ion sample and is closest to a color signal in a copper nanoclusters distribution area on the fluorescent test paper.
