Embedded technology-based olfaction visualization auto-detection device and detection method thereof

Abstract

The invention discloses an embedded technology-based olfaction visualization auto-detection device and a detection method thereof. One end of a 220V alternating current power supply is connected with a switch, the other end of the 220V alternating current power supply is connected with an input end of a voltage converter, an output end of the voltage converter is connected with an input end of a voltage stabilizing chip, an output end of the voltage stabilizing chip is connected independently with an ARM module, a camera and a display, the ARM module is connected with the camera, and the camera aligns with a visual sensor array. The device uses a low-cost ARM platform and enables a protective gas in olfaction visualization detection to be automatically introduced by combining the embedded technology and the olfaction visualization technology, full reaction time of a gas to be detected with visual sensors is automatically judged, images are automatically processed before and after a reaction, and a user is provided with greater convenience and higher speed to finish olfaction visualization detection.

Description

technical field [0001] The invention relates to the detection field of olfactory visualization, in particular to an olfactory visualization automatic detection device based on embedded technology. Background technique [0002] Embedded is a dedicated computer system that is part of a device or device. Embedded technology has developed rapidly in recent years. The embedded industry involves a wide range of fields, such as many industries: mobile phones, PDAs, car navigation, industrial control, military industry, multimedia terminals, gateways, and digital TVs. [0003] Olfactory visualization is a brand-new electronic nose concept. This technology performs qualitative and quantitative analysis of gases according to the color change before and after the reaction between the visual sensor and the gas to be measured. Sensor detection in olfactory visualization technology not only utilizes weak interactions such as the van der Waals force between gas-sensitive materials and the...

AI Technical Summary

Problems solved by technology

[0004] In the existing detection devices of olfactory visualization technology, the protective gas—nitrogen gas is introduced manually, the sufficient reaction time between the gas to be tested and the visual sensor is judged manually, and the image acquisition and processing before and after the reaction are also processed manually. The tightness is not strong, the judgment of sufficient response time is not accurate, and the image processing before and after the response is repeated and cumbersome.
