Air purifier based on NB-IOT

Abstract

The invention discloses an air purifier based on the NB-IOT. The air purifier comprises an air detection module, an air purification module and a center processor module which are connected through anNB-IOT communication module. The air purifier further comprises a particulate matter sensor used for monitoring dust particles in the air and a harmful gas sensor used for monitoring formaldehyde, nitric oxide and ammonia gas in the air. The monitored concentration value of PM2.5 in the air and the concentration value of the formaldehyde or the nitric oxide or the ammonia gas are transmitted to the center processor module, and the center processor module compares the concentration values with a preset value and sends out a purification instruction according to the comparison result. The air purification module conducts air purification according to the purification instruction. The communication module using the NB-IOT technology is adopted in the transmitting process, network signals aregood, and the problem that the monitoring information, the purification instruction and the like cannot be effectively transmitted without the broadband network and mobile data or under the conditionof poor signals and thus the air cannot be effectively purified is solved; the power consumption is small and cost is low; and the comparison result can be transmitted to a mobile terminal, so that the functions of remote monitoring, control and the like are achieved.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an intelligent air purifier based on NB-IOT technology. Background technique [0002] At present, air purifiers are widely used in household, commercial and industrial buildings to absorb, decompose and transform indoor air pollutants, which can effectively improve air cleanliness, greatly improve air quality, and achieve the purpose of purifying air. In related technologies, air purifiers use broadband or mobile data networks to transmit air quality information or alarm signals, and then perform air purification or remote operation for air purification; the cost of using broadband networks or mobile data networks to transmit information is relatively high, and there is no broadband network. In the case of poor network access or mobile data signal coverage, air purification cannot be performed effectively. Contents of the invention [0003] In view of this, the embodiment of th...
