Embodiment Construction

[0032] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] Such as figure 1 As shown, the multi-channel electronic nose detection system of the present invention includes: an air chamber sampling part, a signal conditioning circuit, a main control module, an alarm module, a display module and a 4G transmission module; wherein, the air chamber sampling part includes an air chamber, a sampling device and a signal Acquisition unit.

[0034] The air chamber is designed with anti-corrosion materials. The sampling equipment is used to sample the ambient air and pump the polluted air into the air chamber. The signal acquisition unit is used to collect the gas in the air chamber. Among them, the airtight requirement of the air chamber should be to achieve no gas leakage, the interface of the external sensor of th...

Abstract

The invention discloses a multi-channel electronic nose detection system and a measuring method thereof. The system consists of a gas detection chamber, a signal processing part, a wireless transmission part, an alarm module and a display module, and can monitor various gases, comprising ammonia gas, hydrogen sulfide, carbon monoxide, ethanol, formaldehyde, acetone, VOC and the like, in real time. According to the measuring method, baseline data measurement is added before gas chamber gas entering and sampling, and a time drift correction algorithm is added for gas data, so that gas data analysis is accurate. The system provided by the invention integrates gas detection, data wireless transmission and data storage, is highly integrated and intelligentized, has good auxiliary effect on industrial application, adapts to environment air monitoring of various industrial parks and air monitoring of remote regions, and has wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of gas detection, and in particular relates to a multi-channel electronic nose detection system and a measurement method thereof. Background technique [0002] Ambient air pollution is very harmful to human health. Some gases can cause serious harm to humans and animals in a very small amount, and the concentration of harmful gases and substances in the atmosphere exceeds the limit allowed by the environment, and they will die after a certain period of time. It will change the normal composition of the atmosphere, destroy the natural physical, chemical and ecological balance system, thereby endangering people's life, work and ecological balance system. [0003] Therefore, the detection of the atmosphere is already an indispensable job, and most of the existing industrial park gas monitoring solutions are single gas monitoring or single function, the data of the monitoring system is unstable, and the data dri...
