Product background

With the introduction of environmental protection proposals and a series of environmental protection policies during the NPC and CPPCC sessions, environmental governance focusing on people´s livelihood has become a hot topic that the country attaches great importance to. In fact, not only during this year´s two sessions, but also in previous years, environmental protection has always been a major livelihood issue. Due to the deterioration of atmospheric environment pollution and the increase of haze weather, the environmental pollution caused by rapid economic development has seriously affected the sustainable development of ecological economy and people´s physical and mental health. The national macro policy of environmental protection, pollution reduction and emission reduction has no longer a slogan, and has been effectively implemented in local policies and planning and construction.

However, the increasingly complex situation of air pollution is challenging the traditional monitoring methods of air pollution sources. The number of monitoring points in the monitoring system is limited and the cost is high, and the ability of spatial and temporal dynamic trend analysis and tracking of pollution sources in the monitoring system cannot be deeply explored.

To continue to improve the urban air quality, In response to the 13th Five-Year Environmental Monitoring Quality Management Work Plan of the Ministry of Environmental Protection and the 2017 Air Pollution Prevention and Control Work Plan in The Beijing, Tianjin-Hebei Region and surrounding Areas issued by the Ministry of Environmental Protection, Further implement the Air Pollution Prevention and Control Industry Plan, Comprehensively strengthen the grid management of regional air pollution prevention and control, To achieve the " monitoring without blank, There was no difference in the alignment, One network, one library, one platform " goal, With many years of experience in producing gas detectors, Break through a number of domestic technical barriers, Combined with the Internet of Things data platform flat, The OEN-AQMS micro-ambient air quality monitoring system suitable for mass and grid monitoring has been successfully developed.

Featured function

1.Field- -Ifield field

The intelligent sensing layer realizes multi-dimensional integration, including the in-situ measurement device of particulate matter, the real-time monitoring device of harmful gases, etc.

2.Overstandard alarm

The device can set the alarm threshold and support remote setting. When the data exceeds the alarm threshold, the device will automatically alarm and upload it to the supervision platform to remind the supervisor through the PC platform or mobile wechat terminal. At the same time, it can link the camera for capture and video recording.

3.In-situ particle measurement device

 The equipment mainly realizes the real-time monitoring of dust PM2.5 and PM10.

 The equipment adopts the principle of light scattering to measure the particle concentration. Compared with the traditional β -ray, the microshock balance method measures the dust concentration, which has the advantages of wide applicability, fast measurement speed, convenient operation and maintenance, and online real-time measurement.

 The particulate matter original taste measurement subsystem uses the highly sensitive light scattering photometer (turbidometer) technology to measure the concentration of particulate matter. The particulate matter first passes through the particle cutting device to cut out the PM5 and PM2.5 particles that we need to measure. After cutting, the particulate matter enters the optical measurement room through the sample inlet. The light source produces 880nm of infrared light to scatter on the particles, and the detector located at the 90° angular position will capture the scattered light. Through the relationship between scattered light intensity and calibrated mass concentration of particulate matter, the mass concentration is calculated in real time and transmitted to the data acquisition and processing subsystem. This optical instrument, which ideally reflects the characteristics of particulate matter, provides continuous total suspended particulate matter concentration and cut points from PM10 to PM2.5.

Instrument installed in the air pressure sensor, temperature sensor, and be calibrated after the accurate current hole between the pressure of the digital feedback signal, through the use of such flow control components, accurate control of flow, can obtain accurate sample volume and accurate particle size cutting point, realize the accurate cutting of particulate matter. Particulate matter precision cutting and data optimization ensure the high accuracy of the instrument, comparable to the US EPA certification method. In addition, the particle in situ measurement subsystem is equipped with a heater with temperature and humidity sensor, which can effectively suppress the positive deviation caused by the increase of humidity.
