Four-Faith F2414 IP Modem For Air Quality Online Monitoring System Solution
（1）Monitoring indicators is less than normal，currently China's air quality monitoring network mainly purpose to monitor project for SO2, NOx, and respirable particulate matter,lack of monitoring the reaction of regional air pollution characteristics of pollutants.
（2）Lack of optimization and design of the monitoring network，it is difficult to fully and accurately reflect the air pollution.
（3）Simple methods of automatic air monitoring stations，lack of mobile observation and three-dimensional observation techniques.
The use of wireless communication technology，It is convenient to add and optimize the deployment of the system front-end acquisition equipment,to build a new air quality monitoring system. It's advantage including, flexible networking,short duration and investment saving.
Four-Fiath F2X14 low consumption 4G MODEM，work as the wireless data transmission channel between the front-end and back-end data acquisition monitoring control platform in the system. Specifically responsible for transmission system of data collection，real time connection with platform server, automatically to upload the data collection, and to receive control commands and return status, to achieve real-time, stable and efficient transmission.
The new sytle air quality monitoring system can continuous real-time monitor air quality, dynamic grasp exceeded condition, it is of significant meaning and promotional value to monitor pollution,to prevent pollution event and improve air quality.
System Basi Structure
As picture shown，Air Quality Online Monitoring system will automatically lead control, network communications, computer (or smartphone) and GIS and other information technology into the field of air quality monitoring, Four-Faith F2X14 wireless transmission module which use industrial grade sets up wireless data transmission network, the collection, transmission and monitoring of air quality which achieves various environmental factors.
Four-Faith F2X14 GPRS IP MODEM is a wireless data terminal of Internet of Things , uses public GPRS network to provide users with wireless long-distance data transmission function.
