Description

Technical Field

[0001] The utility model relates to the field of cold chain transportation, and in particular to a monitoring system for accurate and controlled cold chain transportation. Background Art

[0002] In the medical and food industries, vaccines, certain special medicines and foods usually need to be stored and transported under specific low temperature conditions to maintain their effectiveness and food safety. Therefore, the cold chain transportation of related items has become an important link in the field of public food hygiene. Temperature and humidity control during cold chain transportation is essential to maintain the effectiveness of vaccines. Temperature fluctuations or inappropriate storage conditions may cause damage to vaccines, thereby affecting the effectiveness of vaccination programs.

[0003] The existing cold chain transportation solution is to use cold chain vehicles for transportation, and to ensure the safety of goods by controlling the temperature and humidity in the cold chain vehicle compartment. Practice has found that when the vehicle is in use, the cold chain vehicle can maintain a low temperature environment. However, when the vehicle is stopped or the door is opened for operation, the local temperature in the vehicle body often rises. At this time, it is impossible to accurately judge whether the transported goods are still in a safe temperature environment.

[0004] In addition, a cold chain vehicle is usually only used to transport a certain type of item. Because different items require different storage temperatures, a cold chain vehicle cannot transport items with different temperature requirements at the same time, resulting in a waste of transportation resources.
