Refrigerator car safe transportation monitoring method and system

Abstract

The invention discloses a refrigerator car safe transportation monitoring method and system, and the method comprises the steps: obtaining the vibration acceleration of a refrigerator car in real time, and obtaining the vibration amplitude value and vibration frequency value of the current refrigerator car; according to the amplitude value, the amplitude tolerance grade threshold value of the goods currently transported by the refrigerator car, the vibration frequency value and the vibration frequency tolerance grade threshold value of the goods currently transported by the refrigerator car, determining an amplitude parameter and a vibration frequency parameter of the current refrigerator car respectively; according to preset vibration amplitude and frequency weights, performing weighted summation on the amplitude parameter and the vibration frequency parameter to obtain a vibration total parameter value; and when the vibration total parameter value is greater than or equal to a vibration total parameter preset value, outputting vibration state adjustment reminding information. Therefore, according to the refrigerator car safe transportation monitoring method and system provided by the invention, on the premise that the refrigerator car keeps a relatively high speed for rapid delivery, the reminding information can be output when vibration is too large due to too high speed, and goods are prevented from being damaged in the transportation process.

Description

technical field [0001] The present application relates to the technical field of cold chain transportation, in particular to a method and system for monitoring safe transportation of refrigerated vehicles. Background technique [0002] With the improvement of living standards today, people's demand for cold chain logistics continues to increase. As one of the core links of cold chain logistics, cold chain transport vehicles will further increase their demand. Cold chain transport vehicles are generally divided into van refrigerated trucks and semi-trailer refrigerated trucks. The van refrigerated truck has a refrigerated compartment, chassis, and front as one; the semi-trailer refrigerated vehicle is composed of a semi-trailer and a refrigerated compartment. A semi-trailer can be composed of Tractor to tow travel. [0003] In the prior art, refrigerated trucks are generally used to transport goods that cannot be preserved for a long time, such as fresh fruits and vegetables...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, refrigerated trucks are generally used to transport goods that cannot be preserved for a long time, such as fresh fruits and vegetables. They still need to be delivered to the destination quickly under the premise of refrigeration equipment, but if the speed of the vehicle is too fast, it is easy to bump and cause the goods to be damaged. damage

Therefore, during the transportation of refrigerated vehicles, it is often impossible to take into account the requirements of maintaining a high speed for fast delivery and preventing damage to goods caused by excessive speed.
