Embodiment 1

[0051] In this embodiment, a method for identifying the height of cargo throwing is provided, which includes:

[0052] S1. Obtain the three-axis acceleration data of the cargo, and process the three-axis acceleration data to obtain the vector acceleration waveform;

[0053] S2. Determine the cause of the collision of the cargo based on the vector acceleration waveform;

[0054] S3. When the cause of the collision is judged to be throwing, determine the throwing interval and the weightlessness interval based on the vector acceleration waveform, and determine the throwing time and falling time according to the throwing interval and the weightlessness interval;

[0055] S4. Calculate the throwing height and the falling height respectively according to the throwing time and the falling time.

[0056] Based on the characteristics of the vector acceleration waveform during throwing, the method uses the threshold method to determine the throwing start time, throwing time and impact ...

Embodiment 2

[0069] In this embodiment, a cargo throwing height recognition system is provided, including:

[0070] The data acquisition module is used to collect the three-axis acceleration value of the cargo;

[0071] The data processing module is used to carry out vector synthesis to the three-axis acceleration to obtain the vector acceleration waveform;

[0072] The algorithm module is used to determine the throwing interval and the weightless interval based on the vector acceleration waveform, and determine the throwing time and the falling time according to the throwing interval and the weightless interval; and calculate the throwing height according to the throwing time and the falling time and drop height.

[0073] Preferably, the system adopts the cargo throwing height identification method in Embodiment 1. The system executes the specific process described below.

[0074] ① Acquisition and calculation process of cargo throwing height identification method:

[0075] First, the...

Abstract

The invention discloses a cargo throwing height identification method and system. The identification method comprises the following steps: acquiring three-axis acceleration data of a cargo, and processing the three-axis acceleration data to obtain a vector acceleration waveform; judging a collision reason of the cargo based on the vector acceleration waveform; when the collision reason is judged to be throwing, determining a throwing interval section and a weightlessness interval section based on the vector acceleration waveform, and determining upward throwing time and falling time according to the throwing interval section and the weightlessness interval section; and according to the upward throwing time and the falling time, respectively calculating the upward throwing height and the falling height.

Description

technical field [0001] The invention relates to the field of cargo transportation, in particular to a method and system for identifying the throwing height of cargo. Background technique [0002] From the factory to the seller, the product will go through warehousing, handling, and transportation. It will encounter vibration, shock, drop, etc., and even violent handling, such as throwing. The throwing height is a parameter that needs to be paid attention to. Detecting and identifying these behaviors is conducive to targeted improvement of packaging and transportation test methods, product structure and packaging design, locating cargo damage responsibilities, and reducing transportation losses. Therefore, it is necessary to provide a cargo throwing height identification method to analyze and calculate the impact signal received by the product in the transportation environment, identify the throwing height of the product during transportation, and help technicians provide dat...
