Problems solved by technology

In the prior art, in the process of cargo transportation and loading and unloading, three-axis acceleration sensors are often used to record the extreme values ​​​​in the cycle of the three axes of XYZ, and different thresholds are set for different goods or packages to judge whether the goods may be damaged. At present, there are still Cargo labels based on physical characteristics can also be judged afterwards, but the existing technology only achieves quantitative analysis, and cannot make an accurate qualitative analysis of whether the goods are damaged

Embodiment Construction

[0011] Such as figure 1 Shown, a kind of goods transportation state detection method, comprise three-axis acceleration sensor, MCU microprocessor, it is characterized in that, described three-axis acceleration sensor is arranged in the goods packing, during goods transportation process is controlled by described MCU microprocessor Continuously read the values ​​of the three-axis acceleration sensor in the X, Y, and Z axes at a frequency of 1KHz, and then perform real-time algorithm operations. The processing steps are as follows: Initialize system parameters: the static direction DR of the system is the X axis, and the value of DR is Value (DR) assignment 1, free fall altitude counter FALL assignment 0, theoretical stationary wavelet counter SN assignment 0;

[0012] 0. The cycle starts, and the extreme values ​​Xmax, Ymax, and Zmax of the three axes of XYZ in the initialization cycle, the inclination extreme values ​​of the three axes in the cycle AngleXmax, AngleYmax, AngleZ...

Abstract

A method for detecting the state of cargo transportation. Through the basic circuit unit based on the three-axis acceleration sensor and the MCU microprocessor, the MCU continuously reads the original XYZ value of the three-axis acceleration sensor at a frequency of 1KHz, and outputs the goods in real time after processing according to the corresponding algorithm. Real-time qualitative analysis can be realized on the basis of quantitative analysis of the cargo transportation status in each time period. Combined with other communication methods and positioning methods, real-time positioning and alarm can be realized, which is conducive to immediate correction of transportation problems and can also be used for post-event analysis. or hold accountable.

Description

technical field [0001] The invention relates to the field of physics, in particular to a state detection technology of cargo during transportation, in particular to a method for detecting the state of cargo transportation. Background technique [0002] During the transportation, especially the loading and unloading process, the goods often appear in dangerous states and cause damage to the goods. These dangerous states include: falling, bumping, overturning, bumping, etc. In the prior art, in the process of cargo transportation and loading and unloading, three-axis acceleration sensors are often used to record the extreme values ​​​​in the cycle of the three axes of XYZ, and different thresholds are set for different goods or packages to judge whether the goods may be damaged. At present, there are still Cargo labels based on physical characteristics can also be judged afterwards, but the existing technology only achieves quantitative analysis, and cannot make an accurate qu...
