Problems solved by technology

The disadvantage of using the EMD algorithm alone is that there is no strict mathematical proof, and there is still no criterion for evaluating the empirical mode decomposition algorithm. Almost all comparisons are based on subjective judgments and observations, which has caused some Uncertainty
[0009] Based on the above, the existing technology still has the problems of inaccurate measurement results, large noise interference, complicated operation, low efficiency, and possible harm to animals
How to better realize livestock weighing remains to be explored

Embodiment Construction

[0051] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples, but the protection scope of the present invention is not limited thereto.

[0052] refer to figure 1 , the present invention comprises the following steps:

[0053] (1) Collect data; ensure that the livestock is on the weighing platform and continuously collect M data within a certain period of time t;

[0054] (2) Preprocessing the data collected in step (1); judging whether there is a steady state, if there is a steady state, the result will be output; if there is no steady state, the interference value is eliminated by digital filtering;

[0055] (3) Find extreme points in the data eliminated in step (2), delete the data on the left side of the first extreme point and the right side of the last extreme point in the curve, and use the x coordinate of the last extreme point Do mirror image processing for the axis to get the original signal s(t);...

Abstract

The invention provides a livestock scale weighing method. Data pre-processing and an EMD algorithm are combined and a livestock scale weighing method having accurate measuring result, small noise, simple operation and high efficiency and free damages to animals is provided.

Description

technical field [0001] The invention relates to the field of weighing, in particular to a weighing method of an animal husbandry scale. Background technique [0002] How to accurately and conveniently weigh the body weight of livestock has always been a difficult problem. Because the activities of animal husbandry are difficult to control, weighing is very difficult and troublesome to implement, and often requires a lot of manpower and material resources. At present, the method for weighing live livestock is generally to bind the livestock to be weighed, and then use scales or steelyards for weighing. This method is because the accuracy of the scale and the beam itself is not high, and the struggle and shaking of the livestock will also cause It affects the speed and accuracy of weighing, resulting in low accuracy of weighing results; secondly, binding and untying is time-consuming and laborious. If the binding is not tight, the livestock may break free, and if the binding ...
