Embodiment Construction

[0050] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and examples, but the embodiments of the present invention are not limited thereto.

[0051] Empirical Mode Decomposition (EMD) is a new method for dealing with nonlinear and non-stationary signals that has emerged in recent years. However, EMD sometimes has modal aliasing phenomenon, which affects the decomposition effect, is not conducive to analyzing the real physical meaning of the sequence components, reduces the adaptability of the prediction model to each component, and then affects the prediction accuracy. Therefore, CEEMD is proposed. Through noise-assisted analysis, the influence of mode aliasing phenomenon can be weakened, and the analysis effect can be further improved.

[0052]The method of the present invention is mainly based on the overall average emp...

Abstract

The invention relates to a wheat spontaneous biophoton radiation signal analysis method and apparatus. The method comprises the steps of decomposing an obtained wheat spontaneous biophoton radiation signal by adopting an overall average empirical mode decomposition method to obtain intrinsic mode components of all orders; then processing the intrinsic mode components of all the orders to obtain a group of parameters which represent characteristics of the wheat spontaneous biophoton radiation signal; and according to the parameters, analyzing the frequency domain characteristics of the wheat spontaneous biophoton radiation signal. Compared with a method for performing signal analysis on the wheat spontaneous biophoton radiation signal by adopting a Fourier transform method, the method provided by the invention has the advantages that the limitation is overcome; the energy densities of the wheat spontaneous biophoton radiation signal at different moments and frequencies can be described at the same time; the description of a wheat spontaneous biophoton radiation characteristic is more comprehensive, accurate and real; and the information contained in the signal can be fully mined, so that physiological information of wheat is known more clearly.

Description

technical field [0001] The invention belongs to the technical field of biological sciences, and in particular relates to a method and a device for analyzing wheat spontaneous biophoton radiation signals. Background technique [0002] Any living thing has ultra-weak light radiation, called Biophoton Emission (BPE), its intensity is extremely low, it is a response to the state of biological life activities, and it is very sensitive to subtle changes inside the living body. Provides important information on the metabolism and energy conversion of organisms. [0003] Biophoton radiation is divided into two forms: spontaneous biophoton radiation and stimulated biophoton radiation. Stimulated biophoton radiation refers to the biological photon radiation produced by the organism during the stress process when it is subjected to external stimuli (such as light, chemical stimulation, etc.). Biophoton radiation; Spontaneous biophoton radiation refers to the photon radiation produced ...
