And S114, if the sweetness value of the fruits and vegetables is smaller than a preset sweetness value, determining that the odor data of the fruits and vegetables are in a normal state.
Specifically, when the sweetness value of the fruits and vegetables is larger than the preset sweetness value, the fact that the sugar of the fruits and vegetables is accumulated to a certain degree and the fruits and vegetables are volatilized and may begin to rot is indicated, and the odor data of the fruits and vegetables are determined to be in an abnormal state. And conversely, when the sweetness value of the fruits and the vegetables is smaller than the preset sweetness value, the volatile sugar of the fruits and the vegetables is less, and the fruits and the vegetables are not rotten, and the odor data of the fruits and the vegetables are determined to be in a normal state.
And S12, acquiring the image of the fruits and vegetables in the fruit and vegetable transportation area in real time if the odor data of the fruits and vegetables are determined to be in an abnormal state.
In one embodiment, the fruit and vegetable image is an image obtained by shooting fruits and vegetables in a fruit and vegetable transportation area in real time.

In one embodiment, the area ratio is the area ratio of the abnormal region image to the fruit and vegetable image.
In actual operation, the abnormal regions of the fruits and the vegetables can be determined from the fruit and vegetable images through the color characteristics of the fruits and the vegetables, so that the abnormal region images are obtained.
Specifically, the image of the area corresponding to the non-chromaticity value image in the fruit and vegetable image may be an abnormal area image.
Optionally, the corresponding chromatic value of the corresponding fruit and vegetable during rotting can be searched based on the type of the fruit and vegetable, and then the corresponding image area is searched in the fruit and vegetable image according to the corresponding chromatic value during rotting, so that the abnormal area image is obtained.
For example, the corresponding chromatic value of the banana is a black chromatic value when the banana is rotted, a corresponding black area is searched in the fruit and vegetable image, and the black area is used as an abnormal area image.
S16, calculating the ratio of the area of the abnormal area image to the area of the fruit and vegetable image to obtain the area ratio.
Specifically, the area ratio of the two images is calculated, and the area ratio is obtained.
S17, determining the fresh-keeping state of the fruits and vegetables according to the area ratio.
In one embodiment, the current fresh-keeping state of the fruits and vegetables can be determined to be fresh or rotten according to the area ratio.
Wherein, as an example, step S17 may comprise the following sub-steps:
s171, judging whether the area ratio is larger than a preset ratio or not;
s172, if the area ratio is smaller than a preset ratio, determining that the fresh-keeping state of the fruits and vegetables is fresh;
s173, if the area ratio is larger than a preset ratio, determining that the fresh-keeping state of the fruits and vegetables is rotten.
In this embodiment, when the area ratio is smaller than the preset ratio, it is indicated that the number of rotted or damaged fruits and vegetables in the image of the fruits and vegetables is small, the transportation and storage states of the fruits and vegetables are better, and the fresh-keeping state of the fruits and vegetables is determined to be fresh. On the contrary, when the area ratio is larger than the preset ratio, the number of rotten or damaged fruits and vegetables in the image is large, and the freshness keeping state of the fruits and vegetables is determined to be rotten.
