[0001] This invention belongs to the field of air quality monitoring and regulation technology, specifically relating to an air quality monitoring device and a method for analyzing the evolution characteristics of air quality in industrial plant areas. Background Technology

[0002] With the acceleration of industrialization and the increasing severity of air pollution, air quality monitoring and regulation have become crucial aspects of environmental protection. Industrial plants typically contain multiple areas used for product production, processing, and storage, which may release large amounts of pollutants such as particulate matter, carbon oxides, sulfur oxides, and nitrogen oxides, negatively impacting the surrounding environment and human health. Therefore, monitoring and regulating air quality in these areas has become an important means of ensuring air quality. To accurately grasp the spatiotemporal distribution characteristics of pollutants, air quality monitoring devices need to possess high sensitivity, wide coverage, and real-time data transmission capabilities to provide decision support for relevant departments and managers.

[0003] However, existing air quality monitoring devices still have some significant shortcomings in analyzing and adjusting the air quality evolution characteristics of industrial plant areas. First, most existing devices focus on monitoring single pollutants, lacking the ability to jointly monitor multiple pollutants and analyze their spatiotemporal evolution. Second, traditional monitoring technologies struggle to adjust air purification measures in a timely manner based on pollutant concentration trends, often relying on manual intervention or preset trigger thresholds, resulting in slow response times and an inability to adaptively adjust to the air quality evolution of industrial plants. Therefore, a new type of air quality monitoring device and a method for analyzing regional air quality evolution characteristics are needed to address the shortcomings of existing technologies in terms of accurate monitoring, spatiotemporal evolution analysis, and dynamic adjustment.

When each air quality index I i All do not exceed the third set value SD i3 When needed, turn off the adjustment module;

[0011] In the previous work cycle, the air quality index I i Rising to single-item warning value W i In this case, the central processing unit sends the pre-adjustment time-space node for the next working cycle of the adjustment module to the controller.

[0015] As a further optimization of the present invention, a limiting platform is provided on one side of the transport vehicle, which is used to position the gripper and the camera when the transport vehicle is in motion, and a carrier platform is provided on the other side of the transport vehicle, which is used to accommodate the charger of the power supply.

[0016] As a further optimization of the present invention, the robotic arm is used to connect the charger of the power supply to the mobile power supply through the gripper when the power supply is charging. The walking mechanism is provided with a locking mechanism, which is used to connect the walking mechanism to the transport vehicle as one unit.

[0017] As a further optimization of the present invention, the monitoring device is equipped with an air quality index I. i The corresponding first single setting value SD i1 Second single setting value SD i2 Third single setting value SD i3 and single warning value W i And the first comprehensive setting value SS1, the second comprehensive setting value SS2, the third comprehensive setting value SS3, and the comprehensive warning value W′, wherein W i >SD i1 >SD i2 >SD i3 W′>SS1>SS2>SS3;

[0018] The controller is based on various individual air quality indices (I) of the area to be measured. i Calculate the comprehensive air quality index I S When one of the air quality indices I i Rise to the corresponding first single setting value SD i1 Or Air Quality Index I S When the air quality index rises to the first comprehensive setpoint SS1, the controller activates the adjustment module to purify the air in the area under test. Afterwards, when each individual air quality index I... i All do not exceed the corresponding second set value SD i2 And the comprehensive air quality index I SWhen the value does not exceed the second comprehensive setting value SS2, reduce the power of the adjustment module.

[0019] In the previous work cycle, the air quality index I i Rising to single-item warning value W i In the case of, and the comprehensive air quality index I S When the overall warning value W′ rises, the central processing unit sends the pre-adjustment time-space node for the adjustment module's next working cycle to the controller.

[0020] A method for analyzing the evolution characteristics of regional air quality includes the following steps:

[0021] Step 1: During the initial working cycle, the monitoring module collects air quality information of the area to be tested and transmits the air quality information to the controller. The controller obtains the air quality evolution characteristics based on the air quality information and sends control commands to the adjustment module based on the air quality evolution characteristics, so that the adjustment module purifies the air in the area to be tested in the current working cycle. The controller sends the air quality evolution characteristics to the central processing unit.

[0022] Step 2: In the next working cycle, the central processing unit (CPU) sends the pre-adjustment spatiotemporal node for the next working cycle to the controller based on the air quality evolution characteristics of the previous working cycle. The monitoring module collects air quality information of the area to be tested and transmits the air quality information to the controller. The controller obtains the air quality evolution characteristics based on the air quality information and sends control commands to the adjustment module based on the pre-adjustment spatiotemporal node and the air quality evolution characteristics, so that the adjustment module purifies the air in the area to be tested in the current working cycle. The controller sends the air quality evolution characteristics to the CPU.

[0023] The beneficial effects of this invention are as follows:

[0024] 1) This invention collects air quality information of the area to be tested through each air quality detection module of the monitoring module. The controller obtains the air quality evolution characteristics based on the air quality information and uses this to adjust the regulating module in real time, so as to monitor and purify the air quality of each area to be tested in the industrial plant in a timely manner, and avoid the negative impact of industrial production on the surrounding environment and human health.

[0025] 2) Based on the historical air quality evolution characteristics, the central processing unit of the present invention sends the pre-adjustment time and space node of the adjustment module for the next working cycle to the controller according to the warning value of the air quality related index. In the next working cycle, the adjustment module is pre-started to purify the air, reducing the lag of air purification and enabling the device to effectively adapt to the changes in the working conditions of the industrial plant.

[0026] 3) When the adjustment module is pre-started, the adjustment module operates at low power. In subsequent working cycles, if the air quality single index reaches the first single set value or the air quality comprehensive index reaches the first comprehensive set value within the set time after the adjustment module is pre-started, the corresponding pre-adjustment time and space node is retained; otherwise, the corresponding pre-adjustment time and space node is removed, thereby ensuring the effectiveness of air quality adjustment.

[0036] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0037] Example 1

[0038] like Figure 1-3 As shown, this embodiment relates to an air quality monitoring device used to monitor the air quality of a test area in an industrial plant. The air quality monitoring device includes a central processing unit (CPU) 1 and multiple controllers 2, each located in a test area and connected to the CPU 1. Each controller 2 is connected to a monitoring module 3 and a regulating module 4. Industrial plants typically have multiple areas. This embodiment uses a waterworks as an example. Waterworks usually have activated carbon adsorption equipment, biological filters, ozone generators, and may also have combustion power generation facilities. The areas where these facilities are located may generate particulate matter (PM2.5). 2.5 PM 10 Pollutants include carbon monoxide (CO), sulfur dioxide (SO2), nitrogen dioxide (NO2), and ozone (O3). The above areas are all areas to be measured, and each area is equipped with a monitoring module 3, a regulating module 4, and a controller 2.

[0039] Monitoring module 3 is used to collect air quality information of the area to be measured and interacts with controller 2. Controller 2 obtains air quality evolution characteristics based on the air quality information. Specifically, controller 2 calculates the air quality index I based on the air quality information. i And the air quality index I iBy correlating the spatiotemporal attributes of air quality information, air quality evolution characteristics are obtained. Then, controller 2 sends control commands to regulation module 4 based on these characteristics, causing regulation module 4 to purify the air in the monitored area during the current operating cycle. Monitoring module 3 consists of multiple air quality detection modules distributed at different sampling points in the monitored area. Each air quality detection module has one or more air quality sensors to collect air quality information from different sampling points, analyze the types and concentrations of pollutants in the air at different sampling points, and record the sampling time and spatial information. Air quality information includes the monitored value C of pollutant indicator i. i Let i = 1, 2, ..., n, where n is the number of pollutant indicators, and C is the monitoring value of pollutant indicator i. i Specifically, it refers to the average concentration of the i-th pollutant detected by each air quality detection module within the monitoring area.

[0040] Controller 2 is also used to send air quality evolution characteristics to central processing unit 1. Based on historical air quality evolution characteristics, central processing unit 1 sends the pre-adjustment spatiotemporal nodes for the next working cycle of adjustment module 4 to controller 2. The air quality evolution characteristics acquired by central processing unit 1 include the air quality index I of the area under test. i And with the single air quality index I i The corresponding spatiotemporal attributes. The formula for calculating the individual air quality index is as follows:

[0041] ;

[0042] Among them, C i S represents the monitoring value of pollutant indicator i. i This represents the standard value for pollutant indicator i. When the pollutants are SO2, NO2, and PM2.5... 2.5 PM 10 At that time, S i This is the secondary standard limit for the annual average mass concentration of the pollutant; when the pollutant is O3, S i This is the secondary standard limit for the maximum daily eight-hour average mass concentration of the pollutant; when the pollutant is CO, S i This is the secondary standard limit for the daily average mass concentration of this pollutant. The air quality detection module samples air quality information at regular intervals, and the air quality index I... i The spatiotemporal attribute is the corresponding monitoring value C. i The sampling time information and the spatial information of the sampling points of each air quality detection module are used by the central processing unit 1 to calculate the air quality index I. i Then, it is compared with the monitoring value C of pollutant indicator i. i The corresponding time and spatial information are interconnected, and each monitoring value Ci This corresponds to one sampling time information and multiple sampling point spatial information. Central Processing Unit 1 calculates the air quality index I... i The associated time and space information sets the pre-adjusted spatiotemporal nodes.

[0043] The monitoring device is equipped with an air quality index (I) i The corresponding first single setting value SD i1 Second single setting value SD i2 Third single setting value SD i3 and single warning value W i Among them, for the same pollutant, W i >SD i1 >SD i2 >SD i3 When one of the air quality indices I... i Rise to the corresponding first single setting value SD i1 When the controller 2 activates the adjustment module 4, it purifies the air in the area to be tested. Then, when each air quality index I... i All do not exceed the corresponding second set value SD i2 At that time, reduce the power of the adjustment module 4, when each air quality index I i All do not exceed the third set value SD i3 When this happens, turn off adjustment module 4.

[0044] In the previous work cycle, the air quality index I i Rising to single-item warning value W i In this case, the central processing unit 1 sends the pre-adjustment spatiotemporal node for the next working cycle of the adjustment module 4 to the controller 2. In this embodiment, a working cycle is one day. The pre-adjustment spatiotemporal node includes the pre-start time and workstation of the adjustment module 4 for the next day. The pre-start time is related to the time information transmitted by the monitoring module 3, specifically the air quality index I of the previous day. i Rising to single-item warning value W i The previous time was earlier than the previous day's Air Quality Index (I). i Rising to the single warning value W i The previous adjustment module 4 start-up time; the pre-start station monitors the spatial information transmitted by module 3, specifically the previous day's air quality index I. i Rising to single-item warning value W i At that time, the sampling point where the air quality detection module with the highest concentration of the i-th pollutant is located.

[0045] The monitoring module 3 consists of multiple air quality detection modules; the adjustment module 4 includes an air quality adjustment mechanism 41 for purifying air, a workstation adjustment mechanism 42 for moving the air quality adjustment mechanism 41, and a power supply 43 for supplying power to the air quality adjustment mechanism 41. The workstation adjustment mechanism 42 includes a carrier 421, a robotic arm 422 mounted on top of the carrier 421, a gripper 423 mounted on the output end of the robotic arm 422, and a camera 424 mounted on one side of the gripper 423.

[0046] like Figure 7 As shown, the air quality conditioning mechanism 41 includes a housing 411 mounted on a workstation adjustment mechanism 42. Air inlets 412 are evenly distributed at the bottom of the side wall of the housing 411, and an air outlet 413 is located on one side of the top of the housing 411. Inside the housing 411, from bottom to top, are arranged a first filter 414, a second filter 415, a fan 416, and a negative ion generator 417. The negative ion generator 417 is positioned near the air outlet 413. A guide plate is also provided on the top inner side of the housing 411. The first filter 414 is used to filter out large particulate pollutants, and the second filter 415 and the negative ion generator 417 are used to further purify the air and remove other pollutants. In this embodiment, the second filter 415 is preferably made of activated carbon filter material. An ultraviolet light source is also provided inside the housing 411. Furthermore, in other embodiments, for different pollutants to be tested, other existing air purification equipment can be used to replace the air quality conditioning mechanism 41, as long as the purpose of purifying the air in the target industrial plant can be achieved.

[0047] During the initial working cycle, controller 2 only controls the regulating module 4 based on the air quality information collected by monitoring module 3. The position of air quality regulating mechanism 41 is adjusted by the station adjustment mechanism 42 of regulating module 4, so that air quality regulating mechanism 41 moves towards the air quality index I. i Rise to the corresponding first single setting value SD i1 When the air quality detection module detects the highest concentration of the i-th pollutant, it purifies the air by adjusting the air quality adjustment mechanism 41 of module 4. It should be noted that the air quality index I... i Rise to the corresponding first single setting value SD i1 At that time, fan 416 is operated at its first power. Afterwards, when each air quality index I... i All do not exceed the corresponding second set value SD i2 At this time, the power of the regulating module 4 is reduced so that the fan 416 operates at a second power, which is less than the first power.

[0048] In subsequent work cycles, controller 2 also adjusts the regulating module 4 in conjunction with the pre-adjustment time-space node, ensuring that it is pre-started at the corresponding sampling point at the time corresponding to the pre-adjustment time-space node, causing fan 416 to operate at the second power and activating negative ion generator 417 to purify the air. Outside of the pre-adjustment time-space node, the regulating module 4 continues to operate according to the initial work cycle's operating mode. If, within a period after the regulating module 4 is pre-started, one of the air quality indices I... i It still rises to the corresponding first single setting value SD i1 If the controller 2 does not retain the pre-adjusted spatiotemporal node in subsequent work cycles, then the controller 2 will retain the pre-adjusted spatiotemporal node in subsequent work cycles.

[0049] The monitoring device also includes a power distribution module 5 and several charging modules 6. The power distribution module 5 includes a storage unit for storing power information of the power supply 43 and a control unit for scheduling the charging modules 6. The control unit of the power distribution module 5 is wirelessly connected to the charging modules 6. The central processing unit 1 is also used to send power information of each power supply 43 to the power distribution module 5 so that the power distribution module 5 can schedule the charging modules 6 to provide power support to the power supply 43.

[0050] The charging module 6 includes a walking mechanism 61 and a mobile power supply 62 mounted on the walking mechanism 61. A limiting platform 425 is provided on one side of the transport vehicle 421. The limiting platform 425 is used to position the gripper 423 and camera 424 when the transport vehicle 421 is moving, ensuring that the transport vehicle 421 can reach the corresponding workstation within the testing area based on the image information collected by the camera 424. When charging the power supply 43 is not required, if the charging module 6 has insufficient power, the walking mechanism 61 will move to the charging area to charge the mobile power supply 62. The charging area is equipped with a charging device, which can be a wired charging device or a wireless charging device. In this embodiment, a wireless charging device is provided in the charging area. The gripper 423 consists of a mounting plate, two gripping blocks slidably mounted on the mounting plate, and a driving component for driving the two gripping blocks to close or open. The mounting plate is fixed to the output end of the robotic arm 422, and the limiting platform 425 has a slot corresponding to the mounting plate. The other side of the transport vehicle 421 is provided with a platform 426, which is used to accommodate the charger of the power supply 43.

[0051] When the robotic arm 422 is charging from the power supply 43, it connects the charger of the power supply 43 to the mobile power supply 62 via the gripper 423. The walking mechanism 61 is equipped with a locking mechanism 63, which connects the walking mechanism 61 to the transport vehicle 421. The walking mechanism 61 is preferably an AGV (Automated Guided Vehicle). Each walking mechanism 61 has at least two locking mechanisms 63. Each locking mechanism 63 includes a first cylinder 631 fixed to the top of one side of the walking mechanism 61, a second cylinder 632 slidably disposed inside the first cylinder 631, and two electromagnets 633 fixed to the bottom of the first cylinder 631 and the top of the second cylinder 632, respectively. The first cylinder 631 and the second cylinder 632 are spring-loaded together. The transport vehicle 421 is equipped with a connecting member 427 corresponding to the locking mechanism 63. This connecting member 427 is preferably a protrusion fixed to one side of the top of the transport vehicle 421, with a connecting groove at the bottom corresponding to the second cylinder 632. After the walking mechanism 61 approaches the carrier vehicle 421, the two electromagnets 633 are energized and repel each other. One of the electromagnets 633 pushes the second cylinder 632 to embed into the connecting groove of the second cylinder 632, thus locking the walking mechanism 61 and the carrier vehicle 421, which facilitates the subsequent charging work.

[0052] Example 2

[0053] This embodiment relates to another air quality monitoring device. The difference between this embodiment and the previous embodiment is that, in the process of controller 2 controlling adjustment module 4, and in the process of central processing unit 1 setting pre-adjustment spatiotemporal nodes, this embodiment also considers various individual air quality indices I. i Together, they have a combined impact on the industrial plant environment.

[0054] The monitoring device is equipped with an air quality index (I) i The corresponding first single setting value SD i1 Second single setting value SD i2 Third single setting value SD i3 and single warning value W i And the first comprehensive setting value SS1, the second comprehensive setting value SS2, the third comprehensive setting value SS3, and the comprehensive warning value W′, wherein W i >SD i1 >SD i2 >SD i3 ,W′>SS1>SS2>SS3。

[0055] Controller 2 calculates the n individual air quality indices I for the area to be measured. i Calculate the comprehensive air quality index I S Air Quality Index I S The calculation formula is as follows:

[0056] ;

[0057] When one of the air quality indexes is I i Rise to the corresponding first single setting value SD i1 Or Air Quality Index I S When the air quality index rises to the first comprehensive setpoint SS1, controller 2 activates adjustment module 4 to purify the air in the area under test. Afterwards, when each individual air quality index I... i All do not exceed the corresponding second set value SD i2 And the comprehensive air quality index I S When the air quality index does not exceed the second comprehensive setting value SS2, reduce the power of the adjustment module 4. i All do not exceed the third set value SD i3 And the comprehensive air quality index I S When the air quality index does not exceed the third comprehensive setpoint SS3, the adjustment module 4 is turned off. (Air Quality Index I) S When the value rises to the first comprehensive setting value SS1, the station of the adjustment module 4 is set at the geometric center of the area to be tested.

[0058] In the previous work cycle, the air quality index I i Rising to single-item warning value W i In the case of, and the comprehensive air quality index I S When the overall warning value W′ rises, the central processing unit 1 sends the pre-adjustment time-space node for the next working cycle of the adjustment module 4 to the controller 2. If the central processing unit 1 sets the pre-adjustment time-space node based on the overall warning value W′, the station for starting the adjustment module 4 is also set at the geometric center of the area to be measured.

[0059] Example 3

[0060] This embodiment relates to a method for analyzing the evolution characteristics of regional air quality, applicable to the monitoring devices in the two embodiments described above. The method includes the following steps:

[0061] Step 1: During the initial working cycle, the air quality information of the area to be tested is collected by the monitoring module 3 and transmitted to the controller 2. The controller 2 obtains the air quality evolution characteristics based on the air quality information and sends control commands to the adjustment module 4 based on the air quality evolution characteristics, so that the adjustment module 4 purifies the air in the area to be tested in the current working cycle. The controller 2 sends the air quality evolution characteristics to the central processing unit 1.

[0062] Step Two: In the next work cycle, based on the air quality evolution characteristics of the previous work cycle, the central processing unit 1 sends the pre-adjustment spatiotemporal node for the next work cycle to the controller 2 for the adjustment module 4. The monitoring module 3 collects air quality information of the area to be tested and transmits the air quality information to the controller 2. The controller 2 obtains the air quality evolution characteristics based on the air quality information and sends control commands to the adjustment module 4 based on the pre-adjustment spatiotemporal node and the air quality evolution characteristics, so that the adjustment module 4 purifies the air in the area to be tested in the current work cycle. The controller 2 sends the air quality evolution characteristics back to the central processing unit 1. In each subsequent work cycle, the workflow in Step Two is repeated, and the pre-adjustment spatiotemporal node is retained or removed according to the working method in the first embodiment, so as to adapt to the working conditions of the industrial plant at different times.
