Embodiment Construction

[0027] The gas sensing device imitating the nose and neck of a mammal is composed of a gas sensor array, a motor and other auxiliary equipment, such as figure 1 shown. There are two gas pipes (hereinafter referred to as air channels) made of impermeable polyethylene material in the device, one end of each air channel is closed, and a gas sensor is installed on the sealed end. There is an included angle of 90° between the two air passages, so that when one air passage faces the odor plume, the speed at which the odor molecules can diffuse from the outside of the pipe to the sealing end is faster. While the other airway is perpendicular to the odor plume, odor molecules can diffuse from the outside of the pipe to the sealed end at a slower rate. The device composed of gas sensor array and airway is somewhat similar in structure and function to the mammalian nose, and the difference in sensor response in the two airways can reflect the plume orientation. Since the gas sensor a...

Abstract

The invention provides a three-dimensional electronic nose imitating the structure and the information processing mechanism of an animal olfactory organ. The electronic nose has two noses and a neck similar to those of a creature; sensors in two nasal passages can respectively sense concentrations of odor molecules from different directions; the neck drives the noses to rotate so as to scan spatial distribution information of odor molecules at different directions of a surrounding environment; then a neural network is used to analyze the distribution information of the odor molecules at different directions of the surrounding environment so as to recognize the direction of an odor source.

Description

technical field [0001] This application relates to a gas detection device, specifically a three-dimensional electronic nose-dangerous goods leakage source detector that imitates the structure and information processing mechanism of animal olfactory organs. Background technique [0002] The emergence of gas sensors has enabled people to have a method that can easily detect gas components in the environment. However, relying solely on the gas sensor, people cannot make the machine judge the direction of the source of the smell through the sense of smell like animals, and then prey according to this direction. In recent years, many scientists have worked hard to find ways to enable machines to find the source of smell. Rozas et al. started the research on artificial olfactory navigation in 1991. Since then, many scholars have been tirelessly carrying out research on the use of mobile robots and gas sensors to locate odor sources. Up to now, olfactory robots can not only searc...
