Olfaction-based perception system

Abstract

The invention discloses an olfaction-based sensing system, which comprises an olfaction sensor array, a central processing module and a power supply module, and is characterized in that the olfaction sensor array is connected with the central processing module, and the power supply module realizes power supply of the sensing system; the olfactory sensor array comprises a plurality of olfactory sensors, the olfactory sensors are arranged at different positions of the intelligent agent in different directions, and each olfactory sensor comprises a plurality of gas sensors, a plurality of wind direction and wind speed sensors, a signal conditioning module, a signal acquisition module, a signal processing module and a wireless module. The device senses gas types, gas concentration, gas mixing degree and gas distribution by utilizing olfactory information in the environment where an intelligent agent is located, can sense object types, object orientations, self position areas and gas source traceability, constructs an environment gas distribution map, provides olfactory perception for the intelligent agent, and improves the overall perception ability of the intelligent agent to the environment.

Description

technical field [0001] The invention belongs to the field of intelligent body perception, and in particular relates to an olfaction-based perception system applicable to intelligent bodies such as intelligent robots, unmanned aerial vehicles, and self-driving vehicles. Background technique [0002] At present, with the rapid development of the intelligent robot industry and the technological advancement of artificial intelligence, the perception, decision-making, and control technologies that can be applied to intelligent agents such as intelligent robots, drones, and self-driving vehicles are also developing rapidly. The perception ability of the environment is the basis for performing subsequent decision-making, planning, and control functions. The perception ability also largely determines the agent's ability to adapt to the environment and the stability and accuracy of performing tasks. At present, the perception of the environment by intelligent agents such as intellige...
