High-resolution differential self-homing intelligent bionic nose system and working method thereof

Abstract

The invention relates to a high-resolution differential self-homing intelligent bionic nose system and a working method thereof, and the system is characterized in that a gas sampling probe carries out the three-dimensional sampling of gas in a space; the high-resolution gas phase component analyzer is used for analyzing the concentration of a specific component in the to-be-analyzed gas at the sampling point; the gas transmission switching device is used for transmitting the gas sampled by the gas sampling probe to the high-resolution gas phase component analyzer; and the grading servo driving device drives one or more of the gas sampling probe, the gas transmission switching device or the high-resolution gas phase component analyzer to linearly move or / and rotate, and moves and is oriented according to the vector direction of the maximum concentration gradient of the sampling point. According to the invention, the source of the gas-phase component (smell) is automatically searched along the maximum gradient propagation trajectory of the concentration of the gas-phase component (smell).

Description

technical field [0001] The present invention relates to a technology and device for finding the source position of unknown physical space of a specific gas component, especially to determine the optimal motion trajectory through multi-point sampling and analysis with fixed relative positions, combined with a hierarchical servo drive device to realize intelligent self-seeking. Background technique [0002] In intelligent bionic perception technology, bionic vision and hearing are relatively mature. Relying on intelligent vision and hearing, it can realize the estimation of the direction and position of the source, and at the same time determine the details of the perceived object, such as graphics and sound content and other information. The perception of visual and auditory position and direction basically follows the objective laws of light and sound transmission. [0003] In real life, because the smell can achieve long-distance transmission and diffusion, and can bypass v...

AI Technical Summary

Problems solved by technology

[0006] First, the failure to perceive the direction and location of the source of a particular component;

[0007] Second, there is no fast tracking for self-adjusting direction;

[0008] Third, there is no learning function for fingerprint information in unknown multi-gas components

On the contrary, due to the use of a simple gas sensor, it is impossible to detect unknown gas components, and it does not have an adaptive learning function; at the same time, its sensitivity is relatively low, and it cannot perceive extremely low concentrations of gas phase components, such as ppm levels; these defects limit Its use in complex atmosphere spaces

[0014] (2) The qualitative and quantitative results of detection and analysis are scalar, which cannot meet the requirements of positioning and seeking

[0017] The existing electronic (or smart, bionic) sense of smell is more of an analysis device for specific gas phase components, and has not yet technically realized the functions of tracking, locating, and determining the source

[0018] (3) The resolution of detection and analysis is low, and it does not have the function of independently distinguishing unknown gas phase components

[0019] Although the above-mentioned various sensors can qualitatively and quantitatively analyze certain gas phase components, there is still a considerable gap with the high resolution required in practical application scenarios, such as the detection baseline at the ppb level

Therefore, it is impossible to detect the diffusivity of gas phase components in a small range, let alone provide positioning information for the direction of diffusion

[0020] In addition, gas-phase component sensors are often aimed at specific components, and cannot achieve simultaneous cross-category detection, let alone provide self-learning functions for unknown gas-phase components

[0021] The existence of the above three types of technical defects has led to the fact that the current electronic (or smart, bionic) nose is actually a simplified version of the gas-phase component analysis instrument or technology, and has not yet been able to independently identify gas components, locate the source, and self-seek.
