Intelligent gas sensor monitoring system based on Internet of things technology

Abstract

The invention discloses an intelligent gas sensor monitoring system based on an internet-of-things technology and relates to the technical field of sensor networks. The system contains a NO2 gas sensor NFC collection module, a NO2 gas sensor zigbee acquisition module, a gateway module and a data center, wherein environmental monitoring related equipment and an individual consumer terminal are connected in a wireless electric signal mode. According to gas concentration signals detected by an intelligent gas detector collection module and a wireless intelligent gas detector signal receiving / transmitting module, the system has a digital signal output function, the signal transmission distance is longer, the transmitted signal is stable and reliable, the sensor works at room temperature, and the system has the advantages of low power consumption, low cost, low speed, capacity of supporting lots of nodes and supporting multiple network topologies, rapidness, reliability and safety. Moreover, a NO2 gas sensor manufactured by adopting an intaglio printing process is short in response time and fast in recovery time under room temperature conditions, and the characteristics of low cost and large-scale preparation can be realized.

Description

technical field [0001] The invention relates to the technical field of sensor networks, in particular to an intelligent gas sensor monitoring system based on Internet of Things technology. Background technique [0002] In recent years, with the development of various industries with toxic gases such as petrochemical, industrial production, biopharmaceuticals, and automobile exhaust, NO 2 The environmental problems caused by gas are becoming more and more prominent. NO 2 It is one of the industrial pollutants that cause environmental problems such as acid rain, photochemical smog and corrosion. At the same time, NO 2 It is a highly toxic gas, which has a strong stimulating effect on the respiratory tract, and in severe cases can cause lung damage or even pulmonary edema. Therefore, NO 2 monitoring has received increasing attention. Traditional sensor designs are based on alumina ceramic sheets or alumina ceramic tubes, which need to work under heating conditions. With th...
