Abstract

The invention relates to a fingerprint recognition system for the comprehensive state of a hazardous atmosphere. The fingerprint recognition system mainly overcomes the problem that conventional single-sensor monitoring systems do not have multipath detection capability, cannot realize recognition of the state of complex atmospheres, real-time early warning, and lack in wireless signal transmission, cloud signal storage, big data analysis and self-learning. The fingerprint recognition system for the comprehensive state of the hazardous atmosphere comprises a sensing chip, a signal conditioning module, a signal transmission module, an air-passage control module, a temperature control module and a data processing module. With such a technical scheme, the above problem is overcome, and the fingerprint recognition system is applicable to fingerprint recognition of the comprehensive state of the hazardous atmosphere.

Description

technical field [0001] The invention relates to a fingerprint identification system for comprehensive state of dangerous atmosphere. Background technique [0002] With the development of "human-computer interaction" intelligent detection technology in virtual environment, multi-component gas sensor, as a functional device for the collection, conversion, transmission and processing of olfactory extension information, has become a It is an indispensable technical tool in the fields of risk warning, analysis and detection. The current development and integration of devices with big data characteristics and artificial intelligence provides favorable strategic support for the design of a new generation of multifunctional integrated sensing systems. Compared with the traditional single-module sensor (CN103257156A), it has a powerful real-time comprehensive environmental analysis ability and a network-based intelligent learning ability. Flexible and extensive use scenarios; not o...
