Urban PM2.5 monitoring system and method based on Beidou and Internet of Things

Abstract

The invention provides an urban PM2.5 monitoring system based on the Beidou and the Internet of Things, and the system comprises a cloud platform, a plurality of gateway devices, and a plurality of monitoring terminal devices. All monitoring terminal devices are in communication connection with all gateway devices through Beidou satellites. The gateway devices are in network communication connection with the cloud platform, and the monitoring terminal devices are used for monitoring of PM2.5, collects monitoring data and position information, and enables the collected monitoring data and position information to be transmitted to the gateway devices through the Beidou satellites. The gateway devices are used for enabling the received detected data to be transmitted to the cloud platform. The cloud platform is used for the analysis, storage and publishing of the received monitoring data. The invention also provides a corresponding urban PM2.5 monitoring method based on the Beidou and the Internet of Things. The system can automatically collect the position information of devices, reduces the construction difficulty, is convenient to maintain, is wide in application range, is stable in communication, and is wide in range of data monitoring.

Description

technical field [0001] The invention relates to the field of environmental monitoring, in particular to an urban PM2.5 monitoring system and method based on Beidou and Internet of Things technology. Background technique [0002] With the change of air pollution characteristics, air fine particulate matter (PM2.5) pollution has become one of the main reasons for the formation and deterioration of haze weather in most parts of my country. Due to the small particle size, large area, and strong activity of PM2.5, it is easy to attach toxic and harmful substances (such as heavy metals, microorganisms, etc.), and it has a long residence time in the atmosphere and a long transportation distance, which is harmful to human health and atmospheric environment quality. The impact is very large. [0003] At present, the harmfulness of PM2.5 has been highly valued by professional researchers at home and abroad, and PM2.5 has been extensively monitored all over the world. In my country, ...

AI Technical Summary

Problems solved by technology

[0006] 1. Stand-alone monitoring equipment with LCD display screen, the detection information is displayed on the screen in real time, the disadvantage is that there is no networking function, and the monitored data cannot be reported

[0007] 2. The network monitoring terminal and data background with Ethernet connection, the terminal can quickly report information to the data background through Ethernet; the disadvantage is that the mobility is not strong enough, and the installation and construction are difficult

[0008] 3. Network monitoring terminal and data background with 3G / 2G communication module. The terminal can quickly report information to the data background through the mobile cellular network. The terminal has strong mobility and is easy to install and construct. The disadvantage is that it depends on the mobile cellular network and is not suitable for field environments. monitor

[0009] In addition, the above PM2.5 terminal detection equipment does not have the ability to automatically collect location information. It is necessary to survey and record the location of the equipment during installation, which has certain construction difficulties and is not suitable for the execution of mobile monitoring tasks. It is also not conducive to Maintenance and replacement of end products
