Description

Technical Field

[0001] The present invention relates to the technical field of ambient air monitoring, and more specifically, to an ambient air monitoring system. Background Art

[0002] At present, air quality monitoring systems are being vigorously constructed across the country, but there are still many problems to be solved. For example, the equipment of existing national air quality monitoring stations is large in volume, difficult to install and high in equipment cost. The distance between each air quality monitoring station is relatively far. Therefore, the number of monitoring stations is small and can only simply reflect the air quality status, unable to provide enough and more comprehensive monitoring data to support government decision-making.

[0003] Therefore, it is necessary to invent an ambient air monitoring system to solve the above problems. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an ambient air monitoring system to solve the problem that the distance between existing national air quality monitoring stations is relatively far, so it can only simply reflect the air quality status and cannot provide enough monitoring data to support government decision-making as mentioned in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An ambient air monitoring system includes a sensor terminal, a video monitoring terminal, an uninterruptible power supply terminal, a data processing terminal, a wireless transmission terminal and a backend processing system. The sensor terminal includes a high-sensitivity light scattering particulate matter sensor and an electrochemical gas sensor, which are used for online monitoring and real-time data collection of environmental parameters and meteorological parameters, and sending real-time monitoring data to its designated data processing terminal according to the specified communication protocol;

[0006] The data processing terminal is used for summarizing and processing the monitoring data monitored by the sensor terminal;

[0007] The wireless transmission terminal is used for wirelessly connecting the data processing terminal and the backend processing system, and sending the monitoring data summarized by the data processing terminal to the backend processing system for analysis and storage through wireless network transmission;

[0008] The backend processing system is used for storing, sorting and analyzing the data uploaded by the wireless transmission terminal;

[0009] The uninterruptible power supply terminal is used for providing uninterrupted power supply to the sensor terminal and the video monitoring terminal;

[0010] The video monitoring terminal is used for real-time video monitoring of the monitoring site and sending the monitoring status to the backend processing system.

[0011] As a further description of the above technical solution, the environmental parameters collected by the sensor terminal include PM 2.5 , PM 10 , CO, NO2, O3 and the concentration of SO2 in the air. The meteorological parameters collected by the sensor terminal include the temperature, humidity, wind speed, wind direction and air pressure parameters of the monitored environment.

[0012] As a further description of the above technical solution, the sensor terminal adopts a dual-sensor array arrangement. Each gaseous monitoring factor contains 2 electrochemical sensors, one of which is a reference sensor. A temperature and humidity sensing unit is installed in the measurement chamber for environmental correction.

[0013] As a further description of the above technical solution, each sensor module of the sensor terminal can be individually plugged, calibrated and replaced.

[0014] As a further description of the above technical solution, the backend processing system is used to classify various other concentration data of the monitored environmental parameters and integrate them into curve charts according to the maximum value, minimum value and average value, etc., and feedback them to the user terminal.

[0015] As a further description of the above technical solution, the backend processing system is provided with a backup unit and a log unit. The backup unit can back up and save the data when the wireless transmission terminal transmits data, so as to facilitate retrieving it in time when the data is lost. The log unit is used to record the time when the data acquisition unit transmits data, which is convenient for viewing the data transmission time record according to needs in the future.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] By setting up grid-shaped sensor terminal monitoring points, the present invention has the advantages of low cost and can be widely deployed to improve the monitoring coverage rate compared with the monitoring equipment of national control points and municipal control points. Moreover, the sensor terminal of the present invention is small in volume and convenient for grid installation in various scenarios. Each module of the sensor terminal can be individually plugged, calibrated and replaced. While being convenient to disassemble, it reduces the impact of different module failures on the overall monitoring data. By introducing a grid-shaped precise monitoring and decision-making system, it can not only comprehensively understand the overall pollution situation in the area, but also conduct special monitoring on key pollution sources, realizing three-dimensional and all-round supervision of the entire area from macro to micro, providing a solid decision-making basis for scientific haze control and precise pollution control. The low-cost, grid-shaped and all-weather air quality automatic on-line monitoring equipment can help the government to understand the air quality status in real time. By combining and deploying miniaturized and small-sized monitoring equipment to form a full-area and high-density "environmental grid monitoring network", it can also greatly reduce the work intensity of the environmental protection department, reduce the supervision cost and improve the supervision efficiency.
