Automatic control feedback cabin and method based on temperature field three-dimensional imaging

Abstract

The invention relates to the field of logistics, in particular to an automatic control feedback cabin and method based on temperature field three-dimensional imaging. A three-dimensional visualizationtemperature field of the whole vehicle is acquired by temperature sensors arranged in the whole vehicle to construct a three-dimensional image, an identification is conducted by means of an RGB colorsystem recognition, a reddish color is selected and the position in the vehicle compartment is marked; the priority is set as one; the dangerous temperature is set as T, and the temperature difference between the temperature at the latest point in time and the dangerous temperature is determined; the smaller value is selected and the position in the vehicle compartment is marked; the priority isset as two; the temperatures are obtained by the temperature sensors periodically, the temperature trend and temperature change within the same time point are determined, and the highest temperature is selected and the position in the vehicle compartment is marked; the priority is set as three; wind division and guiding are conducted through an air inlet pipe by universal air outlets, the air inlet pipe is connected with a cold air source, and the universal air outlets sequentially aim at and blow winds to the positions determined as prior one, prior two and prior three to perform precise cooling.

Description

[0001] The invention relates to the field of logistics, in particular to a self-control feedback carriage and method based on three-dimensional imaging of a temperature field. Background technique [0002] In existing refrigerated vehicles, there are following defects: [0003] The quality of fresh and perishable products is extremely sensitive to fluctuations in the temperature environment, especially during transportation, if the temperature control inside the refrigerated compartment is not accurate and timely, it is easy to cause serious corruption and deterioration of its quality. Refrigerated transportation is an important way to ensure the freshness and quality safety of fresh and perishable food. The refrigeration efficiency and temperature control accuracy of refrigerated trucks during transportation directly affect the freshness and shelf life of perishable foods. The energy consumption of refrigerated vehicles during transportation directly affects the transportati...

AI Technical Summary

Problems solved by technology

During the cooling process of the refrigerated vehicle, because the air supply port is far away from the door, the air supply path is too long, which intensifies the cooling energy consumption, resulting in low cooling efficiency

[0006] The ambient temperature data during the transportation of refrigerated trucks cannot be obtained timely and accurately

During the transportation of existing refrigerated vehicles, due to the small number of temperature sensors inside the vehicle and the unreasonable layout, the environmental temperature data of the vehicle is lost, the data collection is not timely, and the transmission data is inaccurate, etc.

The lack and incompleteness of the ambient temperature data in the compartment directly affects the accuracy of the quality evaluation of fresh and perishable foods during transportation, resulting in the inability to monitor the transportation process

The ambient temperature cannot be collected in real time, which directly affects the dynamic monitoring and timely decision-making management of fresh and perishable foods during transportation

[0007] The compartment is ventilated as a whole, and the air volume of the overall ventilation is large, especially when there are a lot of goods, the cold air cannot be blown directly to places with relatively high temperatures, which wastes energy, and the wind range in the cold air compartment is limited, especially when there are goods. Large wind resistance, difficult to cool quickly

[0008] For example, the traditional single fixed air supply outlet takes as long as 45-50 minutes to supply air, and the power is high, resulting in high energy consumption
