In order to make the technical solution, objects and advantages of the present invention more apparent, the following examples further illustrate the present invention.
The invention relates to a pollution source enterprise supervision method based on big data application, which is used for carrying out periodic continuous monitoring analysis on data conditions generated by operation facility operation behaviors in each operation stage of a pollution source enterprise. Through analysis, whether each stage of pollutant treatment of the corresponding enterprise has regularity of normal operation is determined, and when the analysis shows that a certain operation stage of the enterprise has no regularity, the operation stage behavior of the enterprise or series of irregular behaviors such as abnormal pollutant treatment, interference and the like exist, the condition needs to be identified and registered for subsequent examination or field check.
After comprehensive analysis, if the enterprises are confirmed to have irregular behaviors in the pollutant treatment process, the enterprises and the graded labels need to be registered and processed for confirmation of environmental protection supervision departments.
The application steps of the pollution source enterprise supervision method are as follows:
s1, monitoring and setting operation facilities of the pollution source enterprise in a monitoring period, wherein the operation facilities comprise a first facility set corresponding to a first operation stage, a second facility set corresponding to a second operation stage and a third facility set corresponding to a third operation stage; monitoring for acquisition of first data relating to a first facility, second data relating to a second facility, and third data relating to a third facility; the first data, the second data and the third data have sequential relevance.
S2, performing regularity analysis on the obtained first data, second data and third data respectively to generate a first regularity analysis result related to the first data, a second regularity analysis result related to the second data and a third regularity analysis result related to the third data.
And if one or more analysis results in the rule analysis results are not regular, enabling the corresponding operation facilities to perform first identification registration. And performing registration with the second identifier for the operating facility of the downstream stage associated with the operating facility registered with the first identifier.
The specific application and setting principle of the pollution source enterprise supervision method are as follows:
generally, the operation stage of pollutant treatment of a pollution source enterprise comprises three stages which are arranged in sequence: the method comprises a pollutant production stage for generating pollutants, a pollutant treatment stage for treating the pollutants and a pollutant discharge stage for discharging the pollutants, wherein the three stages have sequential relevance; therefore, the arrangement of the sewage producing stage, the sewage treating stage and the sewage discharging stage is substituted into the arrangement of the first stage, the second stage and the third stage for application. The first facility is a pollution production facility, the second facility is a pollution control facility, the third facility is a pollution discharge facility, the first data is pollution production data, the second data is pollution control data, the third data is pollution discharge data, the first rule analysis result is a pollution production rule analysis result, the second rule analysis result is a pollution control rule analysis result, and the third rule analysis result is a pollution discharge rule analysis result.
The regularity analyzing and processing process is applied by adopting a period analyzing algorithm, and the period analyzing algorithm comprises the following steps:
step 1: analyzing and extracting the characteristics of the enterprise operating facilities.
Extracting the characteristics of the enterprise operating facilities through the attribute vector, wherein the same enterprise is generally provided with n operating facilities in different operating stages, and the n operating facilities can be expressed as < K1,K2,...,Kn＞。
Step 2: analysing a certain operating facility KiWhether the behavior of (2) is regular.
(1) Obtaining an original sequence Ki：
Acquiring data of a certain operating facility within a certain time, and performing data preprocessing operation on the acquired data, wherein the data preprocessing operation comprises one or more modes of missing value filling, noise smoothing or burr removing on the data.
The data after the preprocessing operation can be represented as Ki＝{k1,k2,...,kmWhere m is the total length of data for the facility in operation. If operating the facility KiThere is regularity in the behavior of (a), meaning that K is within time miThe behavior of (2) may be repeated. Therefore, when the minimum period p is found to occur repeatedly, the facility K is operatediThere is regularity in the behavior of; otherwise, if the minimum period p does not exist, the facility K is operatediThere is no regularity in the behavior of (c). There are at least 2 minimum periods p in time m, so p must satisfy
And is

And rounding down.
(2) Construction comparison sequence K'i。
Data K of operating facilities in a certain timeiOffset by minimum period p, construct alignment sequence K'i＝{k′1,k′2,...,k′m-pOf which is K'iThere were a total of m-p data points.
(3) Calculating the original sequence KiAnd comparative sequence K'iObtaining the target minimum period p'
Calculating the original sequence KiAnd comparison sequence K'iThe similarity formula is as follows, wherein Sim (K)i,K′i) Is KiAnd K'iSimilarity of (c), Cor (K)i,K′i) Is KiAnd K'iCoefficient of correlation, Cov (K)i,K′i) Is KiAnd K'iCovariance of (1), Var (K)i) Is KiVariance of (1), Var (K'i) Is K'iThe variance of (c).
Through the above calculation, the similarity Sim (K) was comparedi,K′i) And a threshold value S if all Sims (K)i,K′i) If the value is less than the threshold value S, the operation of the enterprise operation facilities is not regular; on the contrary, if at least one Sim (K) is presenti,K′i) If the value is larger than or equal to the threshold value, the operation regularity of the enterprise operation facilities is indicated.
To satisfy the requirement of repeated comparison operation of sequence similarity, Sim (K) satisfying the above condition is selectedi,K′i) Sorting to select the largest Sim (K)i,K′i) The corresponding minimum period p' is used as the target minimum period of the enterprise operating facility.
And (3) replacing the minimum period p in the step (2) with the obtained target minimum period p' to carry out operation, and repeatedly executing the step (2) and the step (3) to continuously monitor corresponding data generated by the operating facilities by regular judgment.
And step 3: tags for the enterprise abatement facilities are generated and registered.
Judging according to the step 2, if the enterprise management equipment KiThe behavior of the enterprise management and treatment facility is regular, the operation rule of the enterprise management and treatment facility is determined, and the future behavior characteristics of the enterprise can be predicted through past rules. If new data of the enterprise is calculated, the periodicity of the new data is determined, and then the periodicity is compared with the conventional operation rule to determine whether the enterprise is suspected of abnormally operating facilities.
The method specifically comprises the following steps: setting the monitoring period with a first monitoring period and a second monitoring period of different time periods, and acquiring a first period regular condition of an operating facility in the first monitoring period and a second period regular condition of the operating facility in the second monitoring period by applying the step 2; setting a regular deviation standard, comparing the regular deviation of the first periodic regular condition and the second periodic regular condition, and if the compared regular deviation standard is not met, even if the second periodic regular condition is regular, the second periodic regular condition can still be considered as a condition that the operating facilities are suspected to be abnormally operated, and the corresponding operating facilities need to be subjected to third identification registration.
Preferably, the rule deviation criterion is set to 10%, that is, when the similarity sim of the second period is in the range of-1.1 × sim (first period) to 1.1 × sim (first period), the second period may be considered to be in compliance with the rule deviation criterion.
And through the application of the first identification registration, the data generated by the independently judged operating facilities without regularity is subjected to identification registration so as to be applied to subsequent direct tracing audit and verification.
And through the application of the second identification registration, identifying and registering the data generated by the operation facilities in the downstream stage associated with the operation facilities which are judged to have no regularity, so as to be applied to the subsequent retrospective checking. For example: when the pollution production facility is analyzed to have no regularity in a monitoring period, the pollution production facility is subjected to first identification registration, and the pollution treatment facility and the pollution discharge facility in the downstream stages (the pollution treatment stage and the pollution discharge stage) are subjected to second identification registration.
In the subsequent checking process, the specific production application condition of the operation facility related to the first identifier registration is firstly confirmed, if the pollution control data and the pollution discharge data of the downstream of the pollution control facility are judged to be normal if the pollution control facility does not have the analysis regularity condition caused by the change of the real pollution control data, such as the false alarm caused by the analysis error, the false alarm caused by the fault of the data transmission module and the like, the pollution control data and the pollution discharge data of the downstream are judged to be normal, the pollution control data of the pollution control facility can be considered to be the reasonable condition, the data generated by the downstream facility are normal, and the second identifier registration condition of the pollution control facility and the pollution discharge facility is cancelled.
If the pollution production facility does not have the analysis regularity condition due to the real pollution production data change, but the analysis of the downstream pollution control data and the downstream pollution discharge data is judged to be normal, the data generated by the downstream facility can be considered to have abnormal possibility, and the corresponding pollution control facility and the corresponding pollution discharge facility in the monitoring period need to be further checked to confirm the real pollutant treatment result.
And through the application of the third identification registration, the data generated by the corresponding operating facilities with regular deviation in the previous and subsequent monitoring periods are subjected to identification registration for subsequent retrospective check application.
And when the identification result is confirmed to be inaccurate after checking, canceling the identification registration of the corresponding operating facility. Setting a supervision standard for the classification or quantity condition of the identification registration; and according to the corresponding identification registration condition of the enterprise, performing hierarchical label registration on the enterprise according to the supervision standard. For example, three standards are set in the supervision standard in a grading way according to the acquired quantity conditions of the first identifier, the second identifier and the third identifier, and the first-level label registration can be carried out on enterprises with the quantity conditions lower than the set acquired identifier, and the records are green; for enterprises with the number of acquired identifications higher than the set number but not 2 times higher than the set target, performing second-level label registration, wherein the registration is yellow; for businesses that are more than 2 times higher than the setting indicating the number of acquisitions, a third level of tag registration is performed, registering in red. Subsequent environmental law enforcement departments can pay important attention to enterprises marked with red or yellow, so that clear checking guidance is provided for supervision and law enforcement, and the efficiency of supervision and law enforcement is promoted.
In a preferred embodiment, in the above-mentioned hierarchical tag application, the comprehensive score of the enterprise may be calculated by a score aggregation function, and the tag setting for the enterprise may be performed by setting the comprehensive score.
And 4, step 4: checking or checking the identification result on site according to the label information of the alarm, if the identification result exists really, processing the problem that the enterprise treatment facilities are not normal in operation, marking the alarm information as true and placing the true and the false into a case library for continuous optimization of an algorithm model; and if the identification result is not accurate, the alarm information is marked as false and is listed in the case base. And then, when the ratio of the number of the alarm information marks as false to the total number of the alarm information exceeds 5%, triggering a mechanism for recalculating all the steps, retraining the algorithm model by modifying the data of the training set and optimizing parameters by adjusting the value of the minimum period p, thereby providing the accuracy of the algorithm model.
The above description is only a preferred embodiment of the present invention, and those skilled in the art may still modify the described embodiment without departing from the implementation principle of the present invention, and the corresponding modifications should also be regarded as the protection scope of the present invention.
