Description

Technical Field

[0001] This invention relates to the field of environmental protection equipment monitoring technology, specifically a data analysis-based environmental protection equipment monitoring system and method. Background Technology

[0002] With the acceleration of global industrialization, environmental problems such as air pollution, water pollution, and solid waste accumulation are becoming increasingly serious. The importance attached to the protection of the ecological environment is constantly increasing, and the application scope of environmental protection equipment is continuously expanding. Therefore, the demand for improving environmental protection equipment monitoring technology is becoming more and more urgent. Traditional environmental protection equipment monitoring relies heavily on manual detection and data sampling for environmental supervision and pollution analysis. However, this approach suffers from drawbacks such as low detection frequency and limited coverage, failing to capture instantaneous data changes and creating blind spots in environmental monitoring and analysis. While advancements in sensor technology, the Internet of Things (IoT), and big data analytics are driving automation and intelligence in environmental protection equipment monitoring, many industrial parks and zones still rely on targeted threshold warnings or individual device monitoring. These methods often depend on equipment performance; false alarms or missed alarms can lead to delayed assessments of environmental pollution. Furthermore, single-device monitoring lacks the capacity for in-depth data mining of environmental pollution, only alerting to anomalies and failing to correlate pollution sources and distribution, hindering timely and accurate environmental monitoring. Summary of the Invention

[0003] The purpose of this invention is to provide a data analysis-based environmental protection equipment monitoring system and method to solve the problems raised in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A data analysis-based method for monitoring environmental protection equipment, comprising the following steps: Obtain the distribution locations of environmental protection equipment within the region and record real-time environmental pollution monitoring data of the environmental protection equipment; Based on real-time environmental pollution monitoring data, analyze the real-time environmental pollution index of environmental protection equipment, and construct a periodic pollution index curve based on the real-time environmental pollution index to determine the periodic risk pollution index. Curvature synchronization analysis was performed on the periodic pollution index curves of each environmental protection device to identify periodically associated environmental protection devices; parameter vectors were constructed for the periodic risk pollution indices of periodically associated environmental protection devices, and the correlation strength between periodically associated environmental protection devices was analyzed to obtain environmental protection devices with the same source. By constructing a planar vector distribution map, pollution index offset analysis is performed on environmental protection equipment with the same source, and the pollution source is located and the pollution distribution status is output based on the analysis data.

[0005] Furthermore, the location information of each environmental protection device within the area is determined, and tags are recorded based on the location data of each device; the location determination of each device can be achieved through an Internet of Things platform or a positioning system. Real-time environmental pollution monitoring data from various environmental protection equipment is collected and annotated based on the equipment's location information and timestamps. The annotated environmental pollution monitoring data is then stored in a database.

[0006] Furthermore, based on real-time environmental pollution monitoring data from environmental protection equipment, the real-time processing efficiency coefficient K of the environmental protection equipment is calculated. M,t The analysis and calculation are as follows: ; Among them, K M,t C represents the treatment efficiency coefficient of environmental protection equipment M at time t; in,i(t) Let M be the inlet concentration of pollutant of category i at time t; C out,i(t) Let be the outlet concentration of pollutant of category i at time t for environmental protection equipment M; Q(t) be the pollutant treatment capacity of environmental protection equipment M at time t; where the treatment efficiency coefficient is used to reflect the actual removal capacity of the environmental protection equipment for pollutants; The real-time environmental pollution index (HI) of environmental protection equipment is determined based on its real-time treatment efficiency coefficient. M,t The analysis and calculation are as follows: ; Among them, HI M,t Let M be the environmental pollution index of the environmental protection equipment at time t; C st,i W represents the real-time emission limit concentration value for pollutant category i; i Let be the hazard weight coefficient for pollutant category i; where the hazard weight coefficient for each category of pollutant is set manually based on the degree of harm the pollutant causes to the environment. The monitoring time window is determined to divide the period into cycles, and the environmental pollution index of each environmental protection equipment within the cycle is analyzed and obtained. Based on the environmental pollution index of the environmental protection equipment at each time point within the cycle, curve fitting is performed to obtain the cycle pollution index curve of each environmental protection equipment within the cycle. By setting a safe monitoring interval for the cycle pollution index curve value, the risk pollution index is screened to determine the cycle risk pollution index existing on the cycle pollution index curve of each environmental protection equipment.

[0007] Furthermore, the periodic pollution index curves of various environmental protection equipment were coordinated to obtain the curvature values ​​at each time point on the curves. Curvature synchronization analysis was then performed on the curvature values ​​at continuous time points for the periodic pollution index curves of any environmental protection equipment, with curvature error Δu set as a constraint. The analysis is as follows: ; Where M and P represent different environmental protection equipment designations; U M,t and U P,t The curvature of the pollution index curves for environmental protection equipment labeled M and P at time t, respectively; Sr M,P The synchronization rate of the periodic pollution index curves between environmental protection equipment labeled M and P; N(U M,P|t,t+1 N(T) represents the number of consecutive time points on the periodic pollution index curve between environmental protection equipment labeled M and P where the curvature indicates synchronization; N(T) represents the number of time points within the period. Specifically, the absolute value of the difference in curvature at the same time point on the periodic pollution index curve of any environmental protection equipment is calculated, and the calculated value is compared with the curvature error Δu. When the condition in the above formula is met, that is, less than or equal to the curvature error Δu, it is determined that the periodic pollution index curves of M and P environmental protection equipment are curvature synchronized at this moment. After the curvature synchronization analysis and judgment of all time points on the periodic pollution index curves of M and P environmental protection equipment are completed, the number of time points that satisfy the curvature synchronization at consecutive time points is determined, and their proportion in the cycle is analyzed. Set a curve curvature synchronization rate judgment threshold Srx, and filter the periodic pollution index curve synchronization rates between any environmental protection equipment. M,P The environmental protection equipment corresponding to ≥Srx is identified as periodically related environmental protection equipment; Sr M,P <Srx is screened out by environmental protection equipment; Extract the periodic risk pollution index from the periodic pollution index curve of periodically associated environmental protection equipment, and construct the corresponding parameter vector SX=[HI] for each periodically associated environmental protection equipment. S,f1 HI S,f2.... HI S,fj ]; where HI S,fj Let S be the j-th periodic risk pollution index existing on the periodic pollution index curve of the periodic associated environmental protection equipment labeled S; j is the number of periodic risk pollution indices. By performing correlation analysis on the parameter vectors of environmental protection devices associated with any given period, the correlation strength AS between these devices in any given period is obtained. S,Z The analysis is as follows: ; Among them, AS S,Z Let S be the correlation strength between the periodically correlated environmental protection devices labeled S and Z; SX and ZX are the parameter vectors of the periodically correlated environmental protection devices labeled S and Z, respectively; E is the covariance matrix of the parameter vectors of the periodically correlated environmental protection devices labeled Z. By introducing the correlation strength parameter ASS, the correlation strength AS between environmental protection devices in any period is determined. S,ZMake a judgment only if AS S,Z If the value is greater than or equal to ASS, then the corresponding environmental protection equipment in the cycle is determined to be an environmental protection equipment with the same source; otherwise, the corresponding environmental protection equipment in the cycle is determined to be an environmental protection equipment with different sources. Herein, environmental protection equipment with the same source means that the corresponding environmental protection equipment is affected by the same pollution source, so the monitoring data source is consistent; similarly, environmental protection equipment with different sources means that the corresponding environmental protection equipment is affected by different pollution sources, so the monitoring data source is inconsistent.

[0008] Furthermore, the location information of environmental protection equipment with the same source is determined, and the coordinate projection and pollution index offset analysis of the environmental protection equipment with the same source are performed by constructing a planar vector distribution map. The steps for constructing the planar vector distribution map include: Q1.

Q3. Within the area affected by the operation, a secondary plane coordinate system is constructed by using the boundary line of the area affected by the operation as the horizontal axis for the locations of each environmental protection equipment with the same source. Based on the secondary plane coordinate system, the periodic risk pollution index of the environmental protection equipment with the same source and the corresponding time point are used to form coordinates to obtain the distribution of the periodic risk pollution index points of the corresponding environmental protection equipment with the same source in the secondary plane coordinate system. Q4. In the secondary plane coordinate system, connect the risk pollution index points of each period to the origin of the coordinate system and point from the origin to the risk pollution index points of each period to construct the risk pollution index vector of each period; by synthesizing the risk pollution index vector of each period, obtain the combined risk pollution index vector of the corresponding environmental protection equipment with the same source. Q5. Obtain the intersection points of the summation vectors of risk pollution indices for each period within the operation's impact area, and determine the planar center of the operation's impact area; obtain the offset distance between the intersection points of the summation vectors of risk pollution indices for each period and the planar center of the operation's impact area, and calculate the offset degree PIX of the pollution index of each related environmental protection equipment. S The analysis and calculation are as follows: ; Among them, PIX S S represents the degree of deviation in the pollution index of environmental protection equipment with the same source as the label; D S L represents the offset distance between the intersection point of the sum vector of the cycle risk pollution indices of the environmental protection equipment with the same source as label S and the center of the plane of the area affected by the operation; SThe distance between the location of the environmental protection equipment with the same source as label S and the center of the area affected by the operation. The sum vector of the periodic risk pollution index corresponding to the environmental protection equipment with the same source as label S. The modulus; α(D) S ,L S ) is the angle between the line connecting the intersection of the sum vector of the cycle risk pollution index of the environmental protection equipment with the same source as label S and the center of the plane of the operation impact area, and the line connecting the location of the environmental protection equipment with the same source as label S and the center of the plane of the operation impact area. Based on the analysis data of the pollution index deviation of each related environmental protection equipment within the operation impact area, sort them in descending order, take the operation area of ​​the related environmental protection equipment with the maximum value as the pollution source area, and then take the operation area of ​​the other related environmental protection equipment as the pollution impact area.

[0010] Furthermore, the backup distribution positioning unit is used to determine the location information of each environmental protection device within the area; The monitoring data acquisition unit is used to collect environmental pollution monitoring data from various environmental protection devices in real time. The pollution index analysis unit analyzes the real-time processing efficiency coefficient of the environmental protection equipment based on the real-time environmental pollution monitoring data of the environmental protection equipment; and analyzes the real-time environmental pollution index of the environmental protection equipment based on the real-time processing efficiency coefficient of the environmental protection equipment. The risk pollution index determination unit screens risk pollution indices by setting a safe monitoring range for the periodic pollution index curve values, in order to determine the periodic risk pollution index present on the periodic pollution index curve of each environmental protection device.

[0011] Furthermore, the curve synchronization analysis unit coordinates the periodic pollution index curves of various environmental protection equipment to obtain the curvature values ​​at each time point on the curves, and performs curvature synchronization analysis on the curvature values ​​at continuous time points of the periodic pollution index curves between any environmental protection equipment. The associated equipment analysis unit filters the synchronization rate of the periodic pollution index curves between any environmental protection equipment to determine the periodically associated environmental protection equipment; extracts the periodic risk pollution index on the periodic pollution index curve of the periodically associated environmental protection equipment to construct a parameter vector; and obtains the correlation strength between any periodically associated environmental protection equipment by performing correlation analysis on the parameter vectors between any periodically associated environmental protection equipment.
