Description

Technical Field

[0001] The present invention discloses a dynamic atmosphere-controlled fresh-keeping transport structure and a fresh fruit pressure-resistant transport device, which relate to a dynamic atmosphere-controlled fresh-keeping transport structure installed on a fresh fruit pressure-resistant transport device, and belong to the technical field of intelligent logistics, and particularly to a dynamic atmosphere-controlled fresh-keeping transport structure, which monitors the concentration of ethylene gas generated by fruits in a fruit box through a gas monitor, determines the position of the fruit box, and drives a gas outlet plate to swing in the direction of the fruit box by a rotating motor, thereby reducing oxidation reaction between fruits and oxygen, avoiding ethylene accumulation and self-promoting generation of more ethylene, and reducing the generation of ethylene gas. Background Art

[0002] With the continuous development of social economy, people's requirements for quality of life are gradually improving, and the demand for fresh fruits is increasing. The output and varieties of fresh fruits in different regions and seasons are different. Fresh fruits can be delivered directly from the place of production to consumers through fast and efficient logistics transportation, which can meet the needs of consumers to purchase various fresh fruits through e-commerce platforms. In the e-commerce logistics transportation of fresh fruits, fresh fruits with soft and easily damaged skin, such as peaches and grapes, need to be transported under pressure to reduce damage. At present, cartons are mainly used as outer packaging, and foam grids or carton interlayers are used inside to cushion shock and resist pressure, and then multiple cartons are stacked together for transportation. However, each grid of the existing foam grid or carton interlayer is The size of the cartons is fixed and cannot be adjusted according to the size of each fresh fruit. The fresh fruit cannot be completely fixed and clamped, and is prone to shaking and colliding during transportation, resulting in a high damage rate. The fresh fruit inside is only cushioned and shock-absorbing by foam grids or carton interlayers, and the outer packaging carton is not equipped with a shock-absorbing device, which makes the whole body susceptible to shaking, causing mutual collision and damage between the fresh fruits inside. In addition, the stacking of multiple cartons easily leads to the squeezing of the lower cartons by the upper cartons, making the fresh fruits in the lower cartons easily damaged. At the same time, the current transportation method is also unable to monitor the status of fresh fruits in real time, resulting in some fresh fruits being delivered to consumers even when they are squeezed and damaged or deteriorate too quickly, resulting in a poor experience.

[0003] Publication No. CN219687889U discloses a fruit fresh logistics transport packaging box for preventing fruit collision, comprising: a box body; a vent is provided at one end of the box body, a connecting plate is provided at one end of the box body, a long hinge is provided at one end of the box body, a short hinge is provided at one end of the box body, a fixing hole is provided at one end of the short hinge, a connecting groove is provided at one end of the box body, and a connecting column is provided at one end of the box body. The above packaging box is to place multiple fruits in layers on different bubble column pads, not each fruit is placed in a small grid alone, the fruits cannot be completely fixed and clamped, and are easy to shake and collide with each other during transportation, with a high damage rate; multiple packaging boxes need to be stacked in a transport vehicle, which is easy to cause the upper carton to squeeze the lower carton, making the fruit in the lower carton easily damaged; at the same time, the above packaging box cannot monitor the status of the internal fruit in real time, resulting in some fruits being delivered to consumers when they are squeezed and damaged or the degree of rapid deterioration is too serious, resulting in poor experience.

[0004] In order to improve the above problems, the applicant filed a Chinese invention patent application entitled "A Digital Trade Circulation Monitoring System and Pressure Resistance Device for Fresh Fruits". The temperature in the main box is monitored by a temperature sensor, and the humidity sensor is used to monitor whether the fruit in the fruit box is damaged and water is released. The camera is used to monitor whether the fruit is spoiled and rotten. The fruit status can be monitored in real time so that the damaged and spoiled fruit can be handled in time before the fruit is delivered to the consumer, thereby improving the consumer experience. Fruits in the ripening process will release ethylene gas through their own biochemical reactions. Ethylene gas is a natural plant growth hormone that promotes the ripening and decay of fruits. The above device only monitors the temperature, humidity and whether the fruit is spoiled and rotten, but does not monitor and dilute the concentration of ethylene gas, resulting in an excessively high concentration of ethylene gas in the closed main box, which will accelerate the deterioration and decay of the fruit, and the fruit damage rate is high.

After the fruit box (9) is full, the rotating support plate (12) is adjusted upward through the rotating shock-absorbing mechanism so that the fruit box (9) can be easily moved.

The monitoring host (4) controls the air conditioning device in the transport vehicle to turn on and reduce the temperature in the transport vehicle. The humidity sensor collects the humidity at the bottom of the fruit box (9), and sends the collected humidity data signal to the signal converter. The signal converter converts the electrical signal of the received humidity data signal into a digital signal and sends it to the data processor. The data processor compares the humidity data with the preset humidity. If the humidity data is greater than the preset humidity, it means that there is damaged fruit in the fruit box (9).

The data processor performs image segmentation on the digital signals of the received image data, splices the characteristic regions of the fruits obtained by the image segmentation, removes the background images outside the characteristic regions of the fruits, and performs image noise reduction and image enhancement on the images of the characteristic regions of the fruits to obtain the processed target images of the fruits in the cold chain logistics transportation process. The image processing technology is used to extract the color feature data of the fruit surface. If the color feature data in the target image is greater than the preset color feature data, the color feature data of the fruit surface is extracted. If the number of spoiled or rotten fruits in the same fruit box (9) is greater than a preset number, the location of the fruit box (9) where the fruit is located is sent to the monitoring host (4), and the monitoring background notifies the transportation personnel to stop the delivery of the fruit box (9) and notifies the seller to re-deliver the fruit to the consumer. If the number is less than the preset number, the consumer can be notified in advance that there are damaged fruits in the fruit box (9) and compensation can be made. If the consumer disagrees, the delivery of the fruit box (9) can be stopped and re-delivered or refunded, thereby improving the consumer's experience. After arriving at the destination, different fruit boxes (9) are disassembled from the rotating support plate (12) according to the address information of different consumers and delivered to the consumers.

The humidity sensor collects the humidity at the bottom of the fruit box and sends the collected humidity data signal to the signal converter. The signal converter converts the electrical signal of the received humidity data signal into a digital signal and sends it to the data processor. The data processor compares the humidity data with the preset humidity. If the humidity data is greater than the preset humidity, it means that there is damaged fruit in the fruit box and water is leaking. The monitoring host is sent the location of the fruit box. The monitoring background reminds the transportation personnel to check the damage of the fruit in the fruit box in time; the camera collects images of the fruit in each fruit box, and sends the collected image data signal to the signal converter. The signal converter converts the electrical signal of the received image data signal into a digital signal and sends it to the data processor. The data processor performs image segmentation on the digital signal of the received image data, splices the characteristic area of ​​the fruit obtained by the image segmentation, and removes the background image outside the characteristic area of ​​the fruit. At the same time, the image of the characteristic area of ​​the retained fruit is subjected to image noise reduction and image enhancement processing to obtain the target image of the processed fruit in the cold chain logistics transportation process, and uses image processing technology to extract the color characteristic data of the fruit surface. If the color feature data in the target image is greater than the preset color feature data, the fruit is considered to be spoiled and rotten. If the number of spoiled and rotten fruits in the same fruit box is greater than the preset number, the location of the fruit box where the fruit is located is sent to the monitoring host, and the monitoring background notifies the transportation personnel to stop the delivery of the fruit box and notify the seller to re-deliver it to the consumer. If it is less than the preset number, the consumer can be notified in advance that there are damaged fruits in the fruit box and compensation can be made. If the consumer disagrees, the delivery of the fruit box can be stopped, and re-delivery or refund can be carried out to improve the consumer's experience; after arriving at the destination, different fruit boxes are disassembled from the rotating support plate according to the address information of different consumers and delivered to the consumers.
