Description
Technical Field
The invention relates to the technical field of environment monitoring and corresponding data processing, in particular to an environment monitoring system and a monitoring method.
Background
Monitoring of key pollution discharge production sites or key carbon emission production sites based on environmental monitoring and index data processing is a technology which is adopted at present.
For example, chinese patent CN107390606B issued by 8/10/2021 discloses a system for controlling the total amount of pollutants discharged by whole-process monitoring, which is characterized in that a measuring device and a concentration monitoring device are installed on a sewage outlet of a production place to detect the sewage discharge amount of the production place in real time, and the detection device is matched to detect the running state of the device in real time, correct the detection data and realize the whole-process monitoring.
For another example, a chinese patent CN106442872B issued in 2019, 6, month and 4 discloses an intelligent warning method and system for total amount of atmospheric pollutant emission, which provides real-time warning and prediction in the pollutant emission process for relevant departments and production sites by developing a pollutant emission total amount warning and prediction model, and guides power generation production sites to perform scientific total pollutant emission amount control.
For another example, chinese patent CN104931101B issued by the authority of 3, month and 6 days in 2018 discloses a multi-index real-time environment monitoring terminal system and method based on Android, which collects environment information data of each monitoring point through an environment index sensor, transmits the data to an environment monitoring server through a GPRS network, compiles an Android mobile phone APP through the multi-index real-time environment monitoring terminal to realize data access to the environment monitoring server, and adopts a pollution rating module to classify the environment quality into three grades of good, light and heavy pollution by setting a threshold value, and gives an alarm to the environment quality.
The prior art represented by the patent technology basically monitors the environmental emission of the heavy-duty pollution discharge production place or the heavy-duty carbon discharge production place in a total way and monitors the whole indexes, and the operation control of the heavy-duty pollution discharge production place or the heavy-duty carbon discharge production place basically carries out early warning and disposal after the whole emission of the monitored discharge place exceeds the set index upper limit at a certain moment in a discharge cycle.
It is known that an important pollution discharge department or an important carbon discharge department is often a core enterprise or a leading enterprise in a region, the pollution discharge amount or the carbon discharge amount is often determined by the production property of the enterprise, and the enterprise is forced to stop production according to a simple integral discharge index, so that the enterprise is encouraged to gradually replace the original and old kinetic energy conversion in the past index control mode, the new energy in the new and old kinetic energy conversion replaces the old energy in the enterprise production, namely the new technology replaces the old technology, and the new production line replaces the old production line. Under such normal conditions, without reasonable monitoring and index control means, an enterprise may prefer to select a traditional production line to organize production, because although the traditional production line has high pollutant or carbon emission, the production technology is mature, the capacity is high, many links such as raw material cost and pollution control cost are lower than those of a new production line, and the traditional production line is more suitable for short-term benefits of the enterprise.
Therefore, when monitoring and operation control are carried out on key pollution discharge production places or key carbon emission production places based on environment monitoring and index data processing, only new production lines with low emission and old production lines with high emission are reasonably considered and planned to control the emission of the production places to the environment on the basis of not obviously influencing the production process of the production places.
Because the system emission data acquisition unit (sensor) for monitoring and controlling the key pollution discharge production place or the key carbon emission production place based on the environment monitoring and index data processing in the prior art can not acquire emission data according to the production lines with different emission quantities in the production places, and the emission data analysis processing unit (system platform) can not reasonably establish and calculate the emission index according to the production lines with different emission quantities in the production places, how to establish a new environment monitoring hardware and software platform by using the existing monitoring, sensing and data communication technologies, reasonably acquire environment and production data parameters according to the emission characteristics of the production places, scientifically calculate and distribute the emission index, and therefore, technically realizing the environment monitoring and operation control based on the production lines with different emission quantities is a new technical problem.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Example 1
Referring to fig. 1, fig. 1 illustrates a principle of the environment monitoring system according to the present embodiment. The environmental monitoring system of this embodiment is used for monitoring the specific emission in production place to carry out operation control, is the new environmental monitoring hardware and the software platform that utilize a series of monitoring, sensing and data communication technique to establish, in order to realize basic monitoring and control function, this embodiment the environmental monitoring system includes:
and the emission data acquisition unit is used for acquiring the emission data of the production line of the production place. In particular, the emission data acquisition unit may comprise various known sensors for monitoring pollutant emissions, installed in the production line of the production site.
And the emission data analysis and processing unit is a core part of the system platform and is used for receiving the emission data acquired by the emission data acquisition unit, analyzing and processing the emission data and generating a control instruction for the production process of the production place. The emission data analysis processing unit is installed at least at the supervision terminal, but more preferably, the emission data analysis processing unit is installed at both the supervision terminal and the production management terminal, which is convenient for the monitoring and control department to master the emission dynamics and also convenient for the production site management side to master the emission dynamics.
And the operation control unit controls the production process of the production place according to the control instruction generated by the emission data analysis and processing unit. The operation control unit can have a plurality of setting modes according to different control conditions or policy conditions of different regions, the most direct mode is that the operation control unit is arranged at a production place and can directly perform intervention control on the production process of the production place, or the operation control unit is arranged at an energy power management end, like the above, energy control is performed through linkage of related departments, such as water, electricity, fuel gas and the like are suspended, so that the production process of the production place is indirectly intervened, and the two modes are the prior art and are not elaborated too much.
Compared with the existing method for setting the limit of the integral emission when monitoring and intervention control are carried out on the key pollution discharge production site or the key carbon emission production site, the embodiment can realize different control processing modes and different technical effects through the construction of a new hardware and software platform.
Specifically, the environmental monitoring system of this embodiment further includes a production information interaction unit, which is used for communicating with the emission data analysis processing unit and providing production plan data to the emission data analysis processing unit. Moreover, unlike the previous similar systems, the emission data collecting unit of this embodiment collects emission data of at least one high emission production line and emission data of at least one low emission production line in a production site at the same time, where the high emission production line and the low emission production line are alternative production lines for producing similar products, and according to the description of the background art, it is easy to understand that the high emission production line is a production mode that a production site prefers to adopt in a short period in an autonomous decision, and the low emission production line is an effective emission reduction production mode that a supervisor prefers to adopt in the production site.
The technical object of this embodiment is achieved by that the emission data analysis processing unit allocates an emission index according to the production plan data provided by the production information interaction unit, determines an upper emission limit of the high emission production line and a lower emission limit of the low emission production line in a monitoring control period, updates the accumulated emission data of the high emission production line and the accumulated emission data of the low emission production line in the monitoring control period in real time, measures and calculates whether the remaining time in the monitoring control period is sufficient to meet the emission index in real time according to the accumulated emission data and the emission index, generates a control instruction for the production process of the production site according to the measurement and calculation result, and controls the production process of the production site through the operation control unit.
At present, the production information interaction unit is an independent information interaction system (such as an APP program) that needs to be installed at a production management end, but for a long-term stable monitoring object, a production management system (MES platform, etc.) that directly accesses a production place through program extension may be considered subsequently.
Although the type of site of emphasis is not particularly limited, those skilled in the art will be able to implement the monitoring and estimation described above (the present invention will be described below by way of example) in a manner that will allow monitoring to be performed in accordance with current industry features. According to the principle introduced above, the emission data acquisition unit can simultaneously acquire the emission data of a high emission production line and the emission data of a low emission production line of a production site, the production information interaction unit is introduced to provide the production plan data to the emission data analysis processing unit, the monitoring control department can flexibly distribute emission indexes to the production site according to the production plan data provided in advance, determine the emission upper limit of the high emission production line and the emission lower limit of the low emission production line in a monitoring control period, and then calculate whether the residual time in the monitoring control period is enough to meet the emission indexes in real time, so that the production process of the production site can be timely intervened and controlled according to the calculation result.
Through the establishment of the hardware and software platform, environmental and production data parameters can be reasonably collected according to the emission characteristics of a production place, and emission indexes are scientifically calculated and distributed, so that the environmental monitoring and the operation control of the production line based on different emission quantities are technically realized. The solution of the problem has social benefits besides technical effects, because although the scheme of the embodiment still adopts intervention and control measures for production in the production place, compared with the current method of setting the limit of integral emission, the method can endow the production place with a certain free decision right of production arrangement through scientific technical means, and achieves the purpose of guiding the production place to reasonably reduce emission while ensuring production.
The technical scheme of the embodiment is particularly suitable for monitoring the pollutant emission of the key production site, but the application of the system is not limited to this, and the carbon emission is generally considered not to belong to the pollutant emission, but obviously, the technical scheme of the embodiment can also be used for monitoring the carbon emission of the key production site.
Example 2
In this embodiment, the monitoring method adopted by the environmental monitoring system based on embodiment 1 is provided by way of example only, and since the production operation types of the key production places in different regions are different, the product types are different, and the pollution emission types are different, at least the data establishment method in the monitoring method provided by this embodiment may be adjusted or changed, that is: the present embodiment provides a typical but non-limiting solution with a high applicability.
Specifically, according to the monitoring principle already described in embodiment 1, the following monitoring steps are performed:
s1, an emission data analysis processing unit distributes emission indexes according to production plan data provided by a production information interaction unit, and determines an emission upper limit of a high emission production line and an emission lower limit of a low emission production line in a monitoring control period;
s2, simultaneously acquiring the emission data of at least one high emission production line and the emission data of at least one low emission production line in a production place by an emission data acquisition unit, updating the accumulated emission data of the high emission production line and the accumulated emission data of the low emission production line in the monitoring control period in real time, and measuring and calculating whether the residual time in the monitoring control period is enough to meet the emission index in real time according to the accumulated emission data and the emission index;
s3, generating a control instruction aiming at the production process of the production place according to the measuring and calculating result in the step S2, and controlling the production process of the production place through an operation control unit;
in the operation principle of the environmental monitoring system described in embodiment 1 and the above-mentioned steps mentioned in this embodiment, the emission data analysis processing unit may allocate an emission index according to the production plan data provided by the production information interaction unit, and the calculation manner for determining the emission upper limit of the high emission production line and the emission lower limit of the low emission production line in a monitoring control period may be:
Q H ＝M·A％·P H ；
Q L ＝M·B％·P L ；
wherein,
Q H for monitoring the emission index, Q, allocated to a high-emission production line during a control period L The emission indexes distributed to the high-emission production line in the monitoring control period are monitored;
m is the total production plan amount in the monitoring control period;
a% is the proportion of the planned production quantity distributed to the high-emission production line in the monitoring and control period, B% is the proportion of the planned production quantity distributed to the low-emission production line in the monitoring and control period, and A% + B% =100%;
P H is the theoretical unit product emission value, P, of a high emission production line L Is the theoretical unit product emission value of a low-emission production line.
The unit emission value of a production site is checked according to products, which is a common checking or predicting mode at present, for example, for a high-emission foundry casting production site, the theoretical emission value of each ton of castings is checked.
Further, in the operation principle of the environmental monitoring system described in embodiment 1 and the above steps mentioned in this embodiment, the emission data collecting unit is capable of collecting and calculating at least the real-time accumulated emission data Q of the high emission production line in real time H Shi The real-time accumulative emission data Q of the low-emission production line L fruit And the measured unit time emission value P of the high emission production line H Shi The actually measured unit time emission value P of the low emission production line L fruit 。
During this step of monitoring, if Q is present H Shi Over Q H The case of (2) indicates that high emission line usage has exceeded the target limit, but this determination is clearly delayed and must be at Q H Shi Has not exceeded Q H Before judging whether the low emission production line residual time in the monitoring control period is sufficient or not.
Therefore, further, in the operation principle of the environmental monitoring system described in embodiment 1 and the above steps mentioned in this embodiment, the remaining time of the low emission production line in the monitoring control period is calculated in real time at least according to the accumulated emission data and the emission index, and the calculation method is as follows:
T l residue ＝(Q L –Q L fruit )/P L fruit ；
Wherein,
T l residue The remaining time of the low-emission production line in the monitoring control period;
Q l fruit Accumulating the emission data of the low-emission production line in real time;
P l fruit Is the measured unit time emission value of the low emission production line.
It should be noted at this stage that P is not yet enabled in the low emission line L fruit Obviously, 0 cannot be substituted, at which point the theoretical full load per unit time emission value (already obtained from previous production verification) of the low emission production line should be introduced instead.
Further, in the operation principle of the environmental monitoring system described in embodiment 1 and the above steps mentioned in this embodiment, the evaluation of whether the remaining time in the monitoring control period is sufficient to complete the emission index is performed by comparing the value of T with the value of T L residue Compared with the theoretical remaining time in the monitoring control period. Specifically, the T is L residue Comparing with the theoretical residual time in the monitoring control period if T L residue If the theoretical remaining time in the monitoring control period is longer than the theoretical remaining time, which indicates that the minimum use requirement of the low-emission production line cannot be met, a control instruction for the production process of the production site can be generated according to the measurement result, and the production process of the production site is controlled through the operation control unit, such as the energy supply related to the high-emission production line is suspended. It is easily understood that the theoretical remaining time is not limited to the natural time, and can be flexibly set according to the actual production shift, for example, the working time of one natural day is 8h or 480min instead of 24h in the case of single-shift production instead of three-shift production.
Compared with the original monitoring system and the original monitoring method, the improved monitoring system and the corresponding monitoring method provided by the embodiment have the advantages that the operation is more scientific, the data establishment and adjustment are more flexible, the environmental monitoring and operation control of the production line based on different emission amounts can be realized through simple software and hardware platform construction and data parameter acquisition and calculation, the adopted emission data acquisition unit can simultaneously acquire the emission data of the high-emission production line and the emission data of the low-emission production line of the production site, the production plan data is provided to the emission data analysis and processing unit through the production information interaction unit, the emission index can be flexibly distributed according to the production plan data provided in advance, the emission upper limit of the high-emission production line and the emission lower limit of the low-emission production line in a monitoring control period are determined, whether the remaining time in the monitoring control period is enough to meet the emission index is measured and calculated in real time, a control instruction aiming at the production process of the production site is generated according to the result, the production process of the production site is controlled through the operation control unit, and a certain technical measure of scientific production introduction and emission reduction for ensuring the free production and emission reduction of the production site is achieved.
Moreover, the monitoring system provided by this embodiment also fully considers the flexibility of the production plan of the production location, further allows the production management end to initiate a production plan change application through the production information interaction unit in the monitoring control period through an application-approval program of the system, and can update the emission index data after the system is approved and confirmed, so as to perform the monitoring control process according to the updated emission index, thereby further providing convenience for the production location.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
