An air quality query and distribution device based on NBiot network and MQTT protocol

Abstract

The invention discloses an air quality inquiry and distribution device based on an NBiot network and an MQTT protocol. The device comprises a multi-type environmental protection monitoring device supporting an NBIoT network. The multi-type environmental protection monitoring device monitors smoke, smoke, oil fume, ozone and VOC, and sends data. An NBIoT interface control part, wherein the NBIoT interface control part is communicatively connected with the multi-type environmental protection monitoring equipment; MQTT protocol parsing and processing control, wherein the MQTT protocol parsing andprocessing control is communicatively connected with the NBIoT interface control to receive the data packet; MQTT data storage control, the MQTT data storage control is communicatively connected withthe MQTT protocol resolution processing control; AQI real-time calculation and publishing control, the AQI real-time calculation and publishing control communicates with the MQTT data storage control, calculates AQI and IAQI, and publishes AQI data. The invention solves the technical problems that users can not realize massive concurrent acquisition and data lag, and achieves the technical effects of grasping AQI data in real time, supporting historical data query and timely and efficient.

Description

technical field [0001] The invention relates to the technical field of air quality monitoring, in particular to an air quality query and release device based on NBiot network and MQTT protocol. Background technique [0002] Reversing the deterioration of the environment and improving the quality of the environment are the ardent expectations of the general public. As people pay more attention to the right to know public information, it is a responsible way to actively release the AQI of air quality information, which shows that the relevant departments monitor air quality, And released it to the public in a timely manner, stating that the authorities were not trying to hide anything. If there are special circumstances, air quality may affect health in a short period of time. The real-time update of air quality forecasts also comes with specific tips and suggestions. People can take specific measures or medicines to avoid prolonged exposure to poor air. Different people and ...
