First, the industry background
In recent years, air quality has always been the focus of everyone's attention, PM2.5, heavy industrial pollution, sandstorms and so on are affecting our health all the time. With the improvement of people's living standards, the intention to understand the facts of their own living environment data is also becoming stronger and stronger. Whether the air quality has changed, how the air index in different regions is, how the trend of change is open, and transparency will also help to promote the improvement of public environmental awareness and the enhancement of self-protection.
At present, the traditional manual sampling and laboratory analysis of atmospheric monitoring in most parts of the continent are still used. There are shortcomings in this way, such as untimely and inaccurate, and when environmental managers deal with problems, it is difficult to understand the real-time discharge of pollutants in polluted areas, and it is impossible to make accurate judgments on the problems in a short period of time. Thus increasing a lot of work and unnecessary losses.
Second, the introduction of real-time air quality monitoring program
The use of Internet of Things technology with wireless sensors and OM302 industrial-grade DTUs to build a real-time air quality monitoring system.
Monitoring points can be identified and sensor nodes can be placed in different areas of the city, and the data can be collected in real time through the Ethernet network and transmitted to the monitoring master station, and the manager can finally configure, manage or collect the backhaul data of the monitoring system at the monitoring master station.
The real-time air quality monitoring system is composed of three parts: the field data collection terminal, the data transmission terminal and the monitoring center terminal. The on-site data acquisition end can monitor and collect the current atmospheric carbon monoxide, carbon dioxide, temperature, humidity, fine particulate matter and other values through sensors; the data transmission terminal is established by the OM302 industrial-grade DTUs in the front end and the monitoring center, and the data results collected by the front end are transmitted to the monitoring center for backup and display; the monitoring center receives, stores, processes, statistically analyzes and provides real-time data query and other tasks for the real-time data transmitted.
The real-time air quality monitoring system composed of these three parts can achieve safety, reliability, accuracy, real-time, comprehensive, fast and more efficient to help regulators complete their work and solve many drawbacks caused by traditional collection.
Product features
The real-time air quality monitoring system integrates information technology such as Internet of Things communication technology, computer, GIS, automatic control into the field of air quality monitoring, and adopts the OM302 industrial-grade DTUS component wireless data transmission network to finally realize the air quality collection, transmission and monitoring of various environmental elements.
1. OM302 has software and hardware dual watchdog technology, automatically monitor the working status, and the equipment is automatically restored abnormally.
2. Support TCP, DCUDP, DCTCP multiple heartbeat detection mechanisms, link abnormal dialing restart, device timing restart, to meet the unattended environment.
3. Maximum support links to 5 data centers, which is convenient for business expansion.
4. Full Netcom industrial grade wireless communication module

Third, the advantages of real-time air quality monitoring program
1. Through the sensor network, a large range of data collection can be carried out in real time, with fast timeliness and high accuracy, which is convenient for unified management.
2. It is very suitable for unattended remote monitoring environments by using OM302 with wireless sensing equipment.
3. There is no need to worry about the environment in some areas that is too harsh to make the equipment unable to operate normally and the personal safety of the collection personnel.
4. The solution provides cloud assistants and equipment express lines, and can also realize remote control functions, which greatly improves the work efficiency of management personnel.
