Description

[0002] With the application of various gases, a variety of toxic and harmful gas products are generated in large quantities, posing a threat to human health and safety. Various gas detection technologies have emerged, such as gas and liquefied gas alarms, smoke (fire) alarms. Especially since Wilkens and Hatman proposed the concept of electronic nose in 1964, gas sensing technology is developing towards a higher level - electronic nose, that is, an intelligent system with certain gas and odor discrimination capabilities.

[0003] The electronic nose PEN3 is an odor detection instrument developed by AIRSENSE in Germany. It is a small, fast and efficient detection system for detecting gases and steam. After training, it can quickly identify single compounds or mixed gases. At present, all research experiments on machine olfaction are carried out through the electronic nose PEN3. Since the electronic nose PEN3 can only directly measure one gas, it is necessary to add a sealed gas chamber to mix the sample gas. During the mixing process, manual operation is required, which will cause differences and instability in the sample gas collection, which is easy to cause deviations in the experimental results and affect the accuracy of the experimental results. At the same time, it is not convenient to operate. Utility Model Content
