Intelligent cold chain transport case detection method

Abstract

The invention discloses an intelligent cold chain transport case detection method. The intelligent cold chain transport case detection method comprises the following steps of installing or embedding stress films and temperature measurement films on the inner side walls of a cold chain transport case, establishing a surface coordinate system for each inner side surface of the cold chain transport case, establishing a temperature coordinate system for each temperature measurement film, establishing a stress coordinate system for each stress film, collecting all stress film data and all temperature film data on each side surface of the cold chain transport case, solving stress film average data and temperature film average data on each side surface, collecting stress coordinate data and temperature coordinate data of a point on the cold chain transport case, comparing the collected stress coordinate data and temperature coordinate data with the stress average data and temperature average data of the side surface, judging whether the stress exceeds a maximum threshold of the stress average data, so as to judge whether the point has beyond-expected deformation or not and judge whether the temperature exceeds a maximum threshold of the temperature average data or not, and thereby judging whether the temperature of the point has beyond-expected temperature change or not.

Description

technical field [0001] The invention belongs to the technical field of cold chain transportation equipment application, and in particular relates to a detection method for a smart cold chain transportation box. Background technique [0002] Cold-chain transportation refers to the transportation that keeps the transported goods at a certain temperature throughout the entire transportation process, whether it is loading and unloading, changing transportation methods, changing packaging equipment, etc. The cold chain transportation method can be road transportation, water transportation, railway transportation, air transportation, or a comprehensive transportation method composed of various transportation methods. Cold chain transportation is an important part of cold chain logistics. Cold chain transportation is costly and involves more complex mobile refrigeration technology and incubator manufacturing technology. Cold chain transportation management includes more risks and u...

Problems solved by technology

It is easy to cause bumps and shakes during the shipping process, and the existing cold chain transport boxes generally do not have the function of force and temperature state detection, and cannot timely grasp the force on the outer wall of the cold chain transport box and the internal temperature state , Once damage and cold source leakage occur, they cannot be detected in time. Some cold chain transport boxes are equipped with basic force state detection instruments and temperature state detection instruments, but they do not have a systematic layout. Although they can be detected by force state detection instruments The local position of the side wall of the cold chain transport box is under stress, but it cannot correspond to which part receives the most severe impact bump or shake, and cannot provide effective reference data during inspection and maintenance. It is still necessary for the staff to check each position Checking one by one, although the temperature state of the local position inside the cold chain transport box can be detected by the temperature state detection instrument, it cannot reflect the overall temperature state inside the cold chain transport box, because the cold source inside the cold chain transport box will slowly balance the heat, so Even if the cold chain transport box is damaged or the cold source leaks, the temperature inside the cold chain transport box will not drop suddenly, but a slow cooling process. If there is an overall detection, the data it reflects is also inaccurate; it is precisely because the existing technology cannot grasp the force state and temperature state of the cold chain transport box as a whole, when the cold chain transport box is damaged and cold When the source leaks, the staff cannot detect it in time, and the refrigerated items will be disturbed by the outside during the transportation of the cold chain transport box or fail because they cannot reach the refrigerated temperature, especially for some important refrigerated items. It is miserable; just because the effectiveness of refrigerated transportation cannot be effectively guaranteed, it affects the development of cold chain transportation equipment application technology, hinders its promotion and application, and affects its practicability
