PM2.5 Testing Equipment

Market background

At present, the issue of PM2.5 has aroused great public concern. It is not only related to public life and urban governance, but also to national image and social stability. However, due to cost reasons, there are few environmental monitoring centers in large and medium-sized cities at present. The data of environmental monitoring can reflect the overall air quality of the city from the macro perspective, but can not reflect the air quality of local areas and specific areas from the micro perspective. Therefore, more environmental monitoring stations need to be built to provide more real-time environmental monitoring data.

A set of PM2.5 environmental monitoring system abroad is priced at 100,000 US dollars, while the domestic price is between 100,000 and 500,000 RMB, which is very expensive. Moreover, each set of equipment needs to be installed in the room, which greatly limits its widespread use. Building more environmental monitoring sites requires huge capital investment, which is too expensive. Yunchuang self-developed PM2.5 cloud monitoring platform, each monitoring point is only one tenth of the price of similar products abroad, as long as hanging on the street lamp and pole can be deployed, relying on solar energy power supply, using relatively high precision imported sensors to collect data, real-time data collected through GPRS will be transmitted to the data center deployed data cube cloud computing database. 。 On cloud computing platform, the air pollution situation of the whole city can be presented accurately in real time, and the pollution process can be tracked dynamically. It also has the ability to query the PM2.5 situation around the public through various terminals. The inexpensive PM2.5 environmental monitoring system complements the current monitoring methods of traditional monitoring sites to meet public environmental needs and enhance the image of the government.

Product introduction

Yunchuang's self-developed PM2.5 cloud monitoring platform breaks through the traditional monitoring methods, uses innovative design concepts to organically integrate environmental protection and cloud computing technology, and constructs cloud computing massive data processing platform. PM2.5 cloud monitoring platform has applied for a number of patents, and is currently being tested in several cities for pilot deployment.

Large-scale deployment of PM2.5 cloud monitoring platform sensor network system, in conjunction with existing environmental monitoring sites, can accurately, timely and comprehensively reflect the current situation and development trend of air quality, provide technical support for air quality monitoring and law enforcement, and provide scientific basis for environmental management, pollution source control, environmental planning, etc.

In order to grasp the real-time monitoring data of PM2.5 in different time periods and different climatic characteristics (including temperature, wind direction and season) in different regions of the city, the monitoring system of PM2.5 is laid out and used effectively in different regions of the city.

Advanced PM2.5 sensors are needed for PM2.5 cloud monitoring platform. Each monitoring system deploys multiple PM2.5 sensors. When any one or several sensors have problems, the sensors are redundant to ensure the normal operation of the environmental monitoring system and the repeatability of environmental monitoring data at this monitoring point.

PM2.5 cloud monitoring platform environment data acquisition equipment uses advanced sensors, low-power MCU technology and network communication technology, with data storage function, can provide convenient data inquiry, through GSM, 3G and other communication methods timely upload environmental monitoring data.

PM2.5 cloud monitoring platform data acquisition and monitoring equipment can be powered by lithium batteries or external AC power supply. If the external power supply is cut off, the batteries in the equipment are directly powered.

PM2.5 cloud monitoring platform constructs cloud computing massive data processing platform, stores massive data in the region, accumulates long-term monitoring data, and provides data for research on environmental capacity, implementation of total amount control, target management, prediction and prediction of environmental quality, and environmental governance.

At present, the monitoring equipment of urban environmental monitoring station is deployed between 20m and 25m above the ground. The environmental monitoring equipment of PM2.5 cloud monitoring platform only needs to be deployed at 1.2-3m above the ground. With compact equipment and flexible deployment mode, it can be deployed on public facilities such as poles.
