Description

Technical Field

[0001] The invention relates to the technical field of environmental monitoring, in particular to a distributed environmental monitoring closed-loop system. Background Art

[0002] With the acceleration of industrialization and urbanization, environmental pollution problems are becoming increasingly serious, and the monitoring and management of environmental quality have become particularly important. Although the existing environmental monitoring technology can meet the basic monitoring needs to a certain extent, its shortcomings are gradually emerging, mainly in the following aspects:

[0003] Existing environmental monitoring technologies often rely on fixed monitoring sites, which are usually set up in key locations in cities or industrial areas. However, due to the limited number of monitoring sites and their uneven distribution, the monitoring range is limited, making it difficult to fully reflect the environmental quality of the entire region. In particular, existing monitoring technologies often cannot effectively cover remote areas or areas with complex terrain.

[0004] Existing monitoring technologies usually require manual data collection and analysis, which is not only time-consuming and laborious, but also has poor timeliness. Since environmental monitoring data needs to be collected and reported regularly, it often cannot reflect changes in environmental quality in real time.

[0005] Existing environmental monitoring technologies often fail to achieve information sharing and interaction between collection modules, which limits the ability to further understand the diffusion range and diffusion ladder of pollutants. The lack of a closed-loop feedback mechanism means that monitoring data cannot be fully utilized to optimize monitoring strategies or improve response efficiency, thus affecting the overall effect of environmental monitoring.

[0006] In view of the above-mentioned shortcomings of existing environmental monitoring technologies, it is necessary to provide a distributed environmental monitoring closed-loop system. Modern environmental monitoring systems usually use distributed monitoring networks, wireless communication technologies, intelligent data processing and analysis and other technical means to achieve real-time monitoring and early warning of environmental quality. Not only does it have a wider monitoring range and higher data timeliness, it can also provide multi-dimensional and comprehensive environmental quality information, providing more powerful support for environmental protection and sustainable development.

DETAILED DESCRIPTION

[0058] See also Figure 1 In the embodiment of the present invention,

[0059] A distributed environmental monitoring closed-loop system, comprising:

[0060] a. Collection module cluster: composed of multiple independent collection modules, each of which includes a sensor, a processing unit and a communication interface. The sensor is used to collect environmental data, the processing unit is used to preprocess the data collected by the sensor, and the communication interface is used to transmit the preprocessed data to the data transmission layer;

[0061] b. Data transmission layer: including but not limited to LoRa, WiFi, and Zigbee wireless communication technologies, receiving data from the acquisition module cluster and transmitting it to the data processing and analysis platform;

[0062] c. Data processing and analysis platform: including a data processing module, a real-time analysis module and a machine learning module. The data processing module is used to further process and integrate the received data. The real-time analysis module is used to perform instant analysis based on the processed data and trigger a response mechanism. The machine learning module uses the data in the historical database to perform model training and prediction to optimize the analysis strategy and response mechanism.

[0063] d. Response mechanism: including automatic response module and manual intervention module. The automatic response module automatically performs corresponding actions according to the results of real-time analysis, and the manual intervention module notifies relevant personnel when necessary and provides data support for their decision-making;

[0064] e. Historical database: used to store long-term environmental monitoring data for model training and verification by the machine learning module;

[0065] f. Collaborative monitoring mechanism: enables each collection module to share and interact with each other, thus improving the coverage and accuracy of overall monitoring.

[0066] Among them, the acquisition module transmits the pre-processed data to the data processing and analysis platform through the data transmission layer. The platform continuously optimizes the response strategy through real-time analysis and machine learning, and responds to the monitored environmental changes through automatic response or manual intervention, forming a closed-loop monitoring and response system.

[0067] See also Figure 2 In this embodiment, the automatic response module includes: after receiving abnormal feedback from a certain acquisition module, the system will automatically adjust the monitoring strategies of these acquisition modules according to the preset response rules and the positional relationship of adjacent acquisition modules. The adjustments include but are not limited to increasing the monitoring frequency, expanding the monitoring range, changing the monitoring parameters, and adjusting the monitoring height to improve the monitoring efficiency of the pollutant diffusion path and range.

[0068] For example, if a certain collection module detects that the concentration of a pollutant in the air exceeds the standard, the adjacent collection module will increase the monitoring frequency of the pollutant and expand the monitoring range to track the diffusion trend of the pollutant.

[0069] See also Figure 3 to Figure 6 In this embodiment, the acquisition module includes:

[0070] Bracket 1, serving as the basic supporting structure of the entire acquisition module;

[0071] The cylinder 2 is fixedly mounted on the bracket 1 and has a hollow interior for containing and guiding air flow;

[0072] A plurality of side cavities 3 are evenly distributed on the side wall of the cylinder 2, and each side cavity 3 is connected to the interior of the cylinder 2 so that air can flow therethrough;

[0073] The centrifugal blades 4 are rotatably arranged inside the cylinder 2, and generate centrifugal force by rotating, thereby guiding air to enter from the air inlet pipe 6 at the bottom of the cylinder 2 and flow upward along the inner wall of the cylinder 2;

[0074] The motor 5 is fixedly arranged at the bottom of the cylinder 2 and is used to drive the centrifugal blades 4 to rotate and generate power for air flow;

[0075] The air inlet pipe 6 is provided through the bottom of the cylinder 2 and communicates with the inside of the cylinder 2, serving as an inlet for air to enter the cylinder 2;

[0076] A plurality of gas sensors 7 , each of which is disposed in a different side cavity 3 , are used to detect and collect the concentrations of different substances in the air flowing through the side cavity 3 .

[0077] The centrifugal blades 4 are driven to rotate by the motor 5, so that the air in the external environment enters the cylinder 2 through the air inlet pipe 6, and flows upward along the inner wall of the cylinder 2 under the action of the centrifugal blades 4, and finally flows through the gas sensor 7 in each side cavity 3, thereby realizing the collection of concentrations of different substances in the air.

[0078] In this embodiment, the connection between the side wall of the cylinder 2 and each side cavity 3 is an air outlet 21, and a baffle 31 is rotatably provided at the air outlet 21, and one side of the baffle 31 is connected to the side wall of the cylinder 2 through a rotating shaft.

[0079] The air outlet 21 can be opened or closed by rotating the baffle 31 , thereby controlling whether the air in the cylinder 2 flows into the corresponding side cavity 3 .

[0080] In this embodiment, a spring 33 is connected between the baffle 31 and the corresponding side cavity 3, and the spring 33 provides elastic force to rotate the baffle 31 to close the air outlet 21;

[0081] An electromagnet 32 ​​is fixed in the side cavity 3 , and the baffle 31 is made of a magnetic conductive material. When the electromagnet 32 ​​is energized, it can adsorb the baffle 31 so that the baffle 31 rotates to open the air outlet 21 .

[0082] That is to say, the opening and closing of each air outlet 21 can be controlled by turning the corresponding electromagnet 32 ​​on and off.

[0083] When a feedback is received from one of the gas sensors 7 of a certain collection module that the pollutant exceeds the standard, the adjacent collection module is automatically adjusted to open only the air outlet 21 of the corresponding gas sensor 7, while the other air outlets 21 are closed. At this time, all the air in the cylinder 2 passes through the gas sensor 7 to improve the monitoring sensitivity of the pollutant, thereby determining the diffusion range and diffusion level of the pollutant.

[0084] In this embodiment, an extension tube 61 is slidably disposed in the air intake pipe 6 , a telescopic cylinder 62 is fixed to one side of the air intake pipe 6 , and the upper end of the telescopic cylinder 62 is fixed to the upper end of the extension tube 61 .

[0085] The sampling height can be adjusted by extending and retracting the telescopic cylinder 62. At different heights, the concentration and distribution of pollutants in the air may be different. By adjusting the sampling height, the pollutant concentration information at a specific height can be captured more accurately, thereby optimizing the sampling quality and improving the accuracy and reliability of the monitoring data.

[0086] See also Figure 7 In this embodiment, the gas sensor 7 is connected to a carrier plate 71 , and the carrier plate 71 is detachably mounted in the side cavity 3 .

[0087] The contacts of the gas sensor 7 can be connected via the carrier plate 71 so that the system can read the value of the gas sensor 7 . Different types of gas sensors 7 can be installed in each side cavity 3 as required via the detachable carrier plate 71 .

[0088] In this embodiment, the gas sensor 7 in the side cavity 3 has two symmetrically arranged guide plates 71 .

[0089] The air in the side cavity 3 can be guided to the surface of the gas sensor 7 by the guide plate 71 , thereby ensuring that the gas sensor 7 can effectively contact the air flowing out of the side cavity 3 .

[0090] In this embodiment, the side of the guide plate 71 away from the gas sensor 7 is rotatably connected to the side cavity 3, and its rotating shaft passes through the outside of the side cavity 3. A gear 73 is fixed to one end of the rotating shaft of the guide plate 71 outside the side cavity 3, and the gears 73 connecting the two guide plates 71 are meshed with each other.

[0091] That is, the two guide plates 71 can change their inclination angles by rotating, so that the distance between the two guide plates 71 is suitable for gas sensors 7 of different sizes, ensuring that the air flowing out of the side cavity 3 can contact the entire gas sensor 7;

[0092] Furthermore, since the two gears 73 mesh with each other, the two guide plates 71 always maintain symmetry.

[0093] In this embodiment, one of the gears 73 is connected to a tightenable knob.

[0094] During the specific implementation, the specific operation and optimization of the acquisition module

[0095] Air flow guidance and sampling: The motor drives the centrifugal blades to rotate, guiding the air into the cylinder and flowing upward along the inner wall. The air flows through the gas sensor in the side cavity to collect the concentration of different substances.

[0096] Air outlet control and sensitivity improvement: The opening and closing of the baffle is controlled by an electromagnet to achieve selective opening of the air outlet. When a gas sensor detects that the pollutant exceeds the standard, the adjacent acquisition module automatically adjusts to open only the air outlet of the corresponding gas sensor to improve the monitoring sensitivity.

[0097] Sampling height adjustment: The height of the extension tube in the air intake pipe can be adjusted through the telescopic cylinder to achieve air sampling at different heights. Optimize sampling quality and improve the accuracy and reliability of monitoring data.

[0098] Gas sensor installation and replacement: Gas sensors are connected via a detachable carrier plate for easy installation and replacement. Different types of gas sensors can be installed in each side cavity as required.

[0099] Adjustment and optimization of the guide plate: The guide plate can be rotated to change its inclination angle to adapt to gas sensors of different sizes. Ensure that the air flowing out of the side cavity can contact the entire gas sensor surface.
