Gas detecting and ventilating device and using method thereof

Abstract

The invention relates to the field of gas detection, and discloses a gas detecting and ventilating device and a using method thereof. The gas detecting and ventilating device comprises a casing, a detecting component and a ventilating component, wherein the detecting component is disposed in the casing and comprises a sensor array, a signal converting part and a signal processing part, and the signal converting part is respectively connected to the sensor array and the signal processing part; the ventilating component is disposed on the casing for exchanging gas in the casing and is communicatively coupled to a control part. The gas detecting and ventilating device provided by the invention can ensure that the gas to be detected and the detecting component are simultaneously sealed in thecasing by providing the detecting component in the casing, thereby improving the contact efficiency between the gas to be detected and the detecting component in the space of the limited closed space,shortening the detection time and ensuring the detection efficiency. In addition, the passive detection in the prior art is changed to active sampling detection, which improves the active response capability of the gas detecting and ventilating device.

Description

technical field [0001] The invention relates to the field of gas detection, in particular to a gas detection ventilation device and a method for using the same. Background technique [0002] Electronic noses have broad application prospects in universal scenarios. At present, there are many supporting detection devices and technologies for the sense of smell in the world. At present, the technology of electronic noses is mainly used to simulate the human olfactory system. Electronic noses, also known as odor scanners, are an emerging Intelligent sensory instruments generally use specific sensors and pattern recognition systems to quickly provide the overall signal of the detected sample, indicating the hidden characteristics of the sample. Electronic nose technology has a short response time and fast detection speed, unlike other instruments, such as gas chromatography sensors and high performance liquid chromatography sensors, which require complex pretreatment processes; i...
