Description

Standard electricity utilization feature library establishing method, environment-friendly monitoring method, system and monitor

Technical Field

The invention relates to the technical field of environmental protection monitoring, in particular to a standard electricity utilization feature library establishing method, an environmental protection monitoring method, a system and a monitor.

Background

Along with the implementation of national environmental protection policies and the efforts of environmental protection law enforcement departments, production enterprises producing polluted gas in various production processes install corresponding waste gas pollution treatment facilities according to the requirements of the environmental protection departments to treat the produced waste gas, and discharge the waste gas after reaching the standard so as to ensure that the urban air is not polluted.

However, the waste gas treatment facilities need to consume a large amount of electricity in the working process, and a large burden is brought to the production and operation of enterprises. Therefore, when some enterprises produce, the treatment facilities are not opened according to the regulations to treat the waste gas, so that the phenomenon of stealing and discharging exists, and the air quality is influenced. This case mainly includes the following three cases:

1. the waste gas treatment facilities are not started according to requirements while the waste gas is produced in the production;

2. the sewage producing equipment is used as a treatment facility for power utilization to deceive the environment-friendly monitoring system;

3. the production is stopped and the production is limited under the condition of severe air.

Because the production enterprises are large in quantity and wide in distribution, and the number of law enforcement personnel of the environmental protection management department of the government is small, the supervision and inspection of the production condition of each enterprise and the operation condition of the waste gas treatment facility cannot be carried out, and the environmental protection supervision and inspection work pressure is huge. In order to solve the problem, technicians in the current environmental protection industry develop various waste gas treatment online monitoring systems. These exhaust-gas treatment's on-line monitoring system all need install a large amount of intelligent ammeter and exhaust-gas test analytical equipment and carry out real-time supervision and real-time analysis to judge whether up to standard the waste gas that the enterprise was dispatched. The scheme has the advantages of high installation cost, high operation and maintenance cost, incapability of being installed and used in a large area, and is particularly not suitable for monitoring small and medium-scale pollution discharge enterprises.

The intelligent electric meter is also proposed to monitor the electricity consumption of the pollution discharge enterprises, for example, the patent application with the application number of 201910685676.1 discloses a linkage system and an application method of the electricity consumption and the exhaust emission of the exhaust gas purification equipment, and provides a monitoring method which uses the ratio of the electricity consumption of the environmental protection facility to the total electricity consumption in production and associates the ratio with the exhaust on-line monitoring and exhausting amount of the exhaust gas in the same time period in a memory; for another example, patent application No. 202010314310.6 discloses a method for matching and processing data of power consumption information of an enterprise related to pollution, which includes extracting power consumption data of the enterprise from a unified interface platform of a power consumption information acquisition system, and comparing the data of frozen power consumption, power and current at an extraction time interval to judge whether pollution treatment equipment is started and works normally.

Compared with the traditional online monitoring methods, the two methods can effectively reduce the cost, but the methods have the problems of low data acquisition density and untimely data, and the traditional power consumption, power consumption power or current is only used for identifying whether the pollution control equipment works normally, so that the power consumption equipment can not be judged to be the pollution control equipment. If other electric equipment is connected to the monitoring rear end of the pollution control equipment in the production process of an enterprise and is matched with corresponding power, the monitoring equipment can be easily deceived. Therefore, only by such a monitoring system, when pollution can not be found completely, the treatment equipment has or does not work normally, the actual monitoring effect is not good, and the supervision requirements of environmental protection departments can not be met.

Referring to fig. 6, a method for establishing a standard electricity usage feature library provided in an embodiment of the present application includes the steps of:

s1, collecting power utilization characteristic data of sewage production equipment and sewage treatment equipment in different working modes; the electricity utilization characteristic data comprises basic electricity utilization characteristic data and advanced electricity utilization characteristic data; the basic electricity usage characteristic data includes (but is not limited to) at least one of electricity usage, power, current, voltage; the advanced power usage characteristic data includes (but is not limited to) at least one of starting current pulse content, active power, current distortion rate;

The standard electricity utilization characteristic library is used for the environmental protection monitoring equipment to inquire the standard electricity utilization characteristic data of the pollution treatment equipment according to the working modes of the pollution production equipment and the pollution treatment equipment so as to calculate the overall similarity.

The method comprises the steps of obtaining standard electricity utilization characteristic library data, and executing the steps when the installation of monitoring equipment is finished, wherein the obtained standard electricity utilization characteristic library data are standard, the installation of the monitoring equipment is generally carried out under the supervision of an environmental protection department, and the states of pollution production equipment and pollution treatment equipment of an enterprise can be checked before and after the installation so as to ensure that the pollution production equipment and the pollution treatment equipment are normal. In fact, as the pollution production equipment and the pollution treatment equipment have aging conditions over time, the standard electricity utilization characteristic data should be updated correspondingly; therefore, the steps can be periodically executed to update the data of the standard electricity utilization feature library under the condition that the pollutant production equipment and the pollutant treatment equipment are ensured to be normal.

The pollution treatment equipment can be divided into a plurality of working modes according to different operating powers, for example, a low-power operating mode, a medium-power operating mode and a rated-power operating mode (but not limited thereto, the operation modes can also be divided into a plurality of working modes), the pollution treatment speeds in different modes are different, and the pollution treatment equipment can also be divided into a plurality of corresponding working modes according to the operating power of the pollution treatment equipment so as to ensure that the pollution treatment efficiency of the pollution treatment equipment is matched with the pollution production speed of the pollution treatment equipment. Under different working modes, the power consumption, the power, the current, the voltage and the like are different, so that the working modes of the pollution production equipment and the pollution treatment equipment can be judged according to the specific value of at least one of the power consumption, the power, the current and the voltage.

The starting current pulse content MC is a high-level characteristic of the power load and can be calculated by the following calculation formula:

wherein

For the maximum value of the current experienced at the moment of start-up,

to achieve a steady state current magnitude before start-up,

to end the start-up process, the steady state magnitude of the current after steady state operation.

The active power is a steady-state high-level characteristic of the electric load, and can be expressed as follows according to a Fourier series expansion formula:

wherein the content of the first and second substances,

in order to be the active power,

the phase of the current lag voltage for the ith harmonic,

is the voltage value of the ith harmonic,

is the ith harmonic current value.

The current distortion rate is the distortion degree of the waveform compared with a stable sine wave, reflects the comparison of effective values of the current among the harmonics, and has the formula:

wherein the content of the first and second substances,

in order to be able to measure the rate of current distortion,

in order to stabilize the effective value of the current of the sine wave,

the current effective value of the current collection period is obtained.

The preprocessing in step S2 may include preprocessing methods (such as removing skip points, filtering, etc.) for the sampled data in the prior art, and may further include classifying, packaging, and storing the collected electricity consumption feature data according to a time period.

In some embodiments, in step S3, the step of normalizing each of the electricity usage characteristic data includes:

1) n-dimensional characteristic vector is formed by using n sampling values of the same electricity utilization characteristic data

；

2) The normalized value of each sample value in the n-dimensional feature vector is calculated by the following formula:

wherein the content of the first and second substances,

a normalized value representing the ith sample value,

representing the original value of the ith sample value,

is the maximum of the sample values in the n-dimensional feature vector,

is the minimum of the sample values in the n-dimensional feature vector;

3) and (3) repeatedly executing the steps 1) and 2) for each type of power utilization characteristic data to finish the normalization processing of all the power utilization characteristic data.

The normalization process is a linear normalization process, and in fact, other normalization processes (such as, but not limited to, a 0-mean normalization) may be used.

In some embodiments, see fig. 7, step S1 is followed by:

s5, judging whether the sewage production equipment and the sewage treatment equipment work normally or not according to the power utilization characteristic data; if yes, executing steps S2-S4; if not, sending out a collection failure alarm signal so that the working personnel can check and maintain the equipment in time.

Specifically, the judgment can be directly carried out according to whether the electricity utilization characteristic data are in the corresponding normal numerical value ranges; for example, if the average value of the sampling values of the at least one type of electricity utilization characteristic data exceeds the corresponding normal value range, the corresponding equipment is judged to be abnormal; or if the proportion of the number of the sampling values exceeding the corresponding normal numerical range in the total number of the sampling values exceeds a preset proportion judgment value in the sampling values of at least one type of electricity utilization characteristic data, judging that the corresponding equipment is abnormal; but is not limited thereto.

In addition, if it is determined in S5 that the pollution generating apparatus and the pollution control apparatus are not both operating normally (i.e., at least one abnormality), the abnormal electricity usage characteristic data is also filtered (i.e., the collected abnormal electricity usage characteristic data is deleted).

Referring to fig. 1, an environmental monitoring method provided in an embodiment of the present application includes the steps of:

A1. acquiring power utilization characteristic data of the pollution production equipment and the pollution treatment equipment of the monitored object; the electricity utilization characteristic data comprises basic electricity utilization characteristic data and advanced electricity utilization characteristic data; the basic electricity utilization characteristic data comprises at least one item of electricity consumption, power, current and voltage; the advanced electricity utilization characteristic data comprises at least one of starting current pulse content, active power and current distortion rate;

A3. inquiring in a standard electricity utilization characteristic library to obtain standard electricity utilization characteristic data of the corresponding pollution treatment equipment according to the working modes of the pollution production equipment and the pollution treatment equipment; the standard electricity utilization characteristic library is obtained by adopting the standard electricity utilization characteristic library establishing method;

According to the method, the total similarity is calculated through the power utilization characteristic data and the corresponding standard power utilization characteristic data and is used for comparing with a preset similarity judgment value, when an enterprise adopts other power utilization equipment to illegally access the imposition pollution discharge equipment to work, although the power can be matched, the total similarity cannot be guaranteed to be larger than the preset similarity judgment value, so that whether the pollution treatment equipment normally works or not can be effectively judged through the comparison of the total similarity and the preset similarity judgment value, and the illegal operation of adopting other power utilization equipment to illegally access the imposition pollution discharge equipment to work can be avoided; can effectively monitor whether the pollution control equipment of enterprises works normally in the production process.

The pollution treatment equipment can be divided into a plurality of working modes according to different operating powers, for example, a low-power operating mode, a medium-power operating mode and a rated-power operating mode (but not limited thereto, the operation modes can also be divided into a plurality of working modes), the pollution treatment speeds in different modes are different, and the pollution treatment equipment can also be divided into a plurality of corresponding working modes according to the operating power of the pollution treatment equipment so as to ensure that the pollution treatment efficiency of the pollution treatment equipment is matched with the pollution production speed of the pollution treatment equipment. Under different working modes, the power consumption, the power, the current, the voltage and the like are different, so that the working mode of the pollution production equipment and the pollution treatment equipment can be judged to be the same according to the condition that the specific value of at least one of the power consumption, the power, the current and the voltage is the same as the corresponding standard value under which working mode (the difference between the specific value and the standard value is smaller than the preset tolerance range, namely the specific value and the standard value are the same).

In step a3, a standard electricity consumption feature library is queried and matched according to the working mode, and standard electricity consumption feature data of the pollution treatment equipment of the corresponding working mode in the standard electricity consumption feature library is used as a query result.

In step a4, the specific method for normalizing the power consumption feature data of the pollution treatment device may refer to the method for normalizing the power consumption feature data in the standard power consumption feature library establishing method, which is not described herein again.

In some embodiments, referring to fig. 2 and 3, the preset similarity determination value includes a first similarity determination value;

thus, step a5 includes:

A501. calculating a first total similarity of the normalized basic power utilization characteristic data of the pollution treatment equipment and the corresponding standard power utilization characteristic data;

A502. judging whether the first overall similarity is larger than a first similarity judgment value or not;

A503. if not, judging that the pollution control equipment works abnormally.

In some preferred embodiments, referring to fig. 2 and 3, the preset similarity determination value includes a second similarity determination value;

thus, step a5 includes:

A504. calculating a second overall similarity between the high-level electricity utilization characteristic data after the normalization processing of the pollution treatment equipment and the corresponding standard electricity utilization characteristic data;

A505. judging whether the second overall similarity is larger than a second similarity judgment value

A506. If not, judging that the pollution control equipment works abnormally.

Preferably, once the abnormal operation of the pollution control equipment is determined, an alarm signal is sent to remind the monitored object (such as an enterprise) of stopping illegal activities in time and/or remind a monitoring person (such as an environmental management person) of the abnormal operation of the pollution control equipment of the monitored object.

In practice, step A5 may include steps A501-A503, but not steps A504-A506; steps A504-A506 may also be included, instead of steps A501-A503; it may also include both steps A501-A503 and A504-A506. And in the third mode, the basic power utilization characteristic number and the advanced power utilization characteristic number are adopted to carry out two times of overall similarity comparison, so that the judgment result is more accurate. For the third mode, as shown in fig. 2, if the first total similarity is not lower than the first similarity determination value, the steps a504-a506 are executed, so that if the basic power utilization characteristic data is adopted, that is, the working abnormality of the pollution control equipment is identified, the advanced power utilization characteristic data does not need to be used for similarity comparison, and an alarm signal can be directly sent out, which is beneficial to reducing the calculation load; alternatively, as shown in fig. 3, steps a501-a503 and steps a504-a506 may be executed in parallel, and if the operation of the pollution treatment device is determined to be abnormal at least once through the overall similarity comparison, the operation of the pollution treatment device is finally determined to be abnormal.

The overall similarity is obtained by summing the accumulated weighted value of a plurality of single electricity utilization feature similarities and the weighted value of a similarity judgment objective function, the single electricity utilization feature similarity is the Euclidean distance between a sampling data set of electricity utilization feature data after normalization processing and a corresponding data set of standard electricity utilization feature data, and the weight of each single electricity utilization feature similarity is set according to a specific similarity algorithm. The overall similarity ranges from 0 to 1.

For example, referring to fig. 4, 5, in some embodiments, the process of performing overall similarity calculations includes steps a1-a 3:

a1. and calculating similarity according to the normalized power utilization characteristic data of the pollution treatment equipment to judge the target function.

Specifically, assuming that m types of electricity utilization characteristic data are collected (if the first overall similarity is calculated, m types of basic electricity utilization characteristic data are collected; if the second overall similarity is calculated, m types of high-level electricity utilization characteristic data are collected), in a judgment period, each type of electricity utilization characteristic data collects N samples, each sample comprises N sampling values (the corresponding standard electricity utilization characteristic data also comprises N data values), and the N samples after normalization processing form an electricity utilization characteristic data sample set; the jth sample of the ith normalized power usage feature data may be represented as

The similarity determination objective function is calculated by the following formula:

wherein the content of the first and second substances,

an objective function is determined for the degree of similarity,

determining an objective function for single phase similarity, D₁As a function of the degree of similarity in the electrical characteristics, D₂As a function of similarity between the classes of electricity usage characteristics,

P is a determination value (probability value) of the similarity determination value. Handle

Is set to satisfy

90% of sample points with small data fluctuation can be reserved, and the judgment influence of 10% of sample points with large fluctuation on the electricity utilization characteristic similarity is eliminated, so that the accuracy of the similarity judgment algorithm can be ensured.

a2. And calculating the single electricity utilization characteristic similarity of each normalized electricity utilization characteristic data and the corresponding standard electricity utilization characteristic data.

Specifically, assuming that m types of electricity utilization characteristic data are collected (if the first overall similarity is calculated, m types of basic electricity utilization characteristic data are collected, and if the second overall similarity is calculated, m types of advanced electricity utilization characteristic data are collected), the ith type of electricity utilization characteristic data in the standard electricity utilization characteristic data set is

Judgment with this bookThe ith kind of electricity utilization characteristic data acquired in the period

The normalized data and the corresponding ith electricity utilization characteristic data

And (3) calculating the similarity of the single power utilization characteristics, wherein the calculation formula is as follows:

wherein the content of the first and second substances,

the similarity of the single electricity utilization characteristics corresponding to the ith electricity utilization characteristic data,

for the normalized single-use characteristic value data set,

standard electricity-only characteristic data stored for initialization.

a3. And calculating the overall similarity according to the similarity judgment target function and the single power utilization feature similarity.

Specifically, the overall similarity is calculated by the following formula:

wherein k1 and k2 can be arranged as required and 0 ≤ k1 ≤ k2 ≤ 1, wherein k1 is

The value of the weight coefficient of (a),

is singly used for the ith kindElectrical feature similarity; k2 is

The value of the weight coefficient,

determining a target function for the single-phase similarity; sim is the overall similarity.

It should be noted that the first similarity determination value and the second similarity determination value may be set according to actual needs, for example, the first similarity determination value is 0.85 to 0.95, and the second similarity determination value is 0.70 to 0.80.

Whether the pollution treatment equipment works normally is judged through the overall similarity of the normalized power utilization characteristic data and the corresponding standard power utilization characteristic data, and compared with the method that whether the pollution treatment equipment works normally is identified only by the numerical range of power consumption, power utilization power or current in the prior art, whether the current power utilization equipment is the pollution treatment equipment or not and whether the pollution treatment equipment is in a normal working state or not can be identified more accurately and intelligently, and a method that an enterprise accesses and matches the pollution treatment equipment illegally through other pollution production equipment can also be effectively found. The similarity of the first total body can be calculated by adopting one or more basic electricity utilization characteristic data, and the recognition accuracy can be further improved by preferably adopting a plurality of basic electricity utilization characteristic data; the second overall similarity may be calculated using one or more types of advanced electricity usage characteristics data, preferably a plurality of types of advanced electricity usage characteristics data, which may further improve recognition accuracy.

In some preferred embodiments, referring to fig. 2 and 3, the environmental monitoring method further includes the steps of:

A6. judging whether the sewage production equipment is started before the sewage treatment equipment according to the power utilization characteristic data of the sewage production equipment and the sewage treatment equipment;

A7. if yes, judging that the monitored object secretly discharges pollutants;

A8. judging whether the sewage production equipment is closed or not compared with the sewage treatment equipment according to the power utilization characteristic data of the sewage production equipment and the sewage treatment equipment;

A9. if yes, judging that the monitored object secretly discharges pollutants.

If the acquired electricity consumption characteristic data includes electricity consumption, in step a6, the determination may be made according to the time when the electricity consumption of the pollution production equipment begins to change and the time when the electricity consumption of the pollution treatment equipment begins to change, and if the time when the electricity consumption of the pollution production equipment begins to change is before the time when the electricity consumption of the pollution treatment equipment begins to change, it is determined that the pollution production equipment is started before the pollution treatment equipment; in step A8, the determination may be made according to the time when the power consumption of the pollution generating equipment begins not to change and the time when the power consumption of the pollution treatment equipment begins not to change, and if the time when the power consumption of the pollution generating equipment begins not to change is after the time when the power consumption of the pollution treatment equipment begins not to change, the pollution generating equipment is determined to be turned off after the pollution treatment equipment.

If the acquired electricity consumption characteristic data includes power consumption, current consumption or voltage consumption, in step a6, the determination may be made according to the time when the power, current or voltage of the pollution production equipment and the pollution treatment equipment changes from zero to non-zero, and if the time when the power, current or voltage of the pollution production equipment changes from zero to non-zero is before the time when the power, current or voltage of the pollution treatment equipment changes from zero to non-zero, it is determined that the pollution production equipment is started before the pollution treatment equipment; in step A8, the determination may be performed according to the sequence of the time when the power, current, or voltage of the pollution production device and the pollution treatment device changes from non-zero to zero, and if the time when the power, current, or voltage of the pollution production device changes from zero to non-zero is after the time when the power, current, or voltage of the pollution treatment device changes from non-zero to zero, it is determined that the pollution production device is turned off after the pollution treatment device. It should be noted that, as shown in fig. 2 and 3, if it is determined in step a6 that the pollution abatement apparatus is not turned on earlier than the pollution abatement apparatus, steps a2-a5 are performed.

By detecting the opening sequence and the closing sequence of the pollution production equipment and the pollution treatment equipment, whether the enterprises have the behavior of stealing and discharging pollutants can be found in time so as to prevent or take other countermeasures in time. Preferably, once the monitored object secretly discharges pollutants, an antitheft warning signal is sent to remind the monitored object (such as an enterprise) of stopping the antitheft behavior in time, and/or remind monitoring personnel (such as environmental protection management personnel) of the existence of the antitheft behavior of the monitored object.

In some preferred embodiments, the environmental monitoring method further comprises the steps of:

A10. acquiring the current accumulated working time of the pollution treatment equipment and the accumulated working time of the last maintenance alarm;

A11. calculating the time difference between the current accumulated working time and the accumulated working time during the last maintenance alarm;

A12. if the time difference reaches a preset time judgment value, a maintenance alarm of the pollution treatment equipment is sent out.

Starting from the installation and use of the detection equipment, the accumulated working time of the pollution treatment equipment starts to be calculated once the pollution treatment equipment works, when the accumulated working time reaches a preset time judgment value, a maintenance alarm of the pollution treatment equipment is sent out to remind a monitoring object to maintain the pollution treatment equipment, monitoring personnel is reminded to supervise the monitoring object to maintain the pollution treatment equipment, the accumulated working time when the maintenance alarm of the pollution treatment equipment is sent out is recorded, when the pollution treatment equipment works subsequently, the accumulated working time is continuously calculated, and the time difference between the actual accumulated working time and the accumulated working time when the previous maintenance alarm is sent out (namely, the accumulated working time recorded when the maintenance alarm of the pollution treatment equipment is sent out last time) is calculated. Therefore, in step a12, the accumulated operating time of the pollution control equipment at the current time is recorded while the maintenance alarm of the pollution control equipment is issued.

According to the environmental protection monitoring method, the power utilization characteristic data of the pollution production equipment and the pollution treatment equipment of the monitored object are obtained; judging the working modes of the sewage production equipment and the sewage treatment equipment according to the power utilization characteristic data; inquiring in a standard electricity utilization characteristic database according to the working modes of the pollution production equipment and the pollution treatment equipment to obtain corresponding standard electricity utilization characteristic data of the pollution treatment equipment; the standard electricity utilization characteristic library is obtained by adopting the standard electricity utilization characteristic library establishing method; carrying out normalization processing on the electricity utilization characteristic data of the pollution treatment equipment; calculating the overall similarity of the normalized power utilization characteristic data of the pollution treatment equipment and the standard power utilization characteristic data, and comparing the overall similarity with a preset similarity judgment value to judge whether the pollution treatment equipment works normally; whether current consumer is the pollution treatment equipment and whether the pollution treatment equipment is in a normal working state can be accurately and intelligently identified, so that the enterprise can not be effective by accessing the illegal of other pollution production equipment to match with the pollution treatment equipment.

Referring to fig. 8, an embodiment of the present application further provides a monitor 100, which includes a data processing and analyzing module (CPU) 101, and a communication module 102, a data acquisition module 103, and a data storage module 104 electrically connected to the data processing and analyzing module 101;
