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 an environment monitoring method.
Background
The implementation and monitoring of key pollution discharge production sites or key carbon emission production sites based on environmental monitoring and index data processing are currently adopted technologies.
For example, chinese patent No. CN107390606B issued by 2021, 8 and 10 discloses a total pollutant emission amount control system for whole-process monitoring, which is implemented by installing a metering device and a concentration monitoring device on a sewage outlet of a production site to detect sewage amount of the production site in real time, and matching with the detection device, detecting the running state of the device in real time, correcting the detection data, and realizing the whole-process monitoring.
As another example, chinese patent No. CN106442872B issued by the publication of 6/4/2019 discloses an intelligent early warning method and system for total emission of atmospheric pollutants, which provides real-time warning and prediction in the process of pollutant emission for relevant departments and production sites by developing a model for total emission warning and prediction of pollutants, and guides the power generation production sites to perform scientific total emission control of pollutants.
For another example, chinese patent No. CN104931101B issued by 3/6/2018 discloses an Android-based multi-index real-time environmental monitoring terminal system and method, which collect environmental information data of each monitoring point through an environmental index sensor, transmit the data to an environmental monitoring server through a GPRS network, write an Android mobile phone APP through the multi-index real-time environmental monitoring terminal to realize data access to the environmental monitoring server, and adopt a pollution rating module to divide environmental quality into three grades of good, light pollution and heavy pollution by setting a threshold, and alarm the environmental quality.
The prior art represented by the above-mentioned patent technology basically adopts the method of carrying out overall monitoring and overall index monitoring on the environmental emission of a heavy-point pollution discharge production place or a heavy-point carbon emission production place, and the operation control of the heavy-point pollution discharge production place or the heavy-point carbon emission production place is also carried out after the overall emission quantity exceeds the set index upper limit at a certain moment in one emission period of the monitored emission place.
It is known that the key pollution discharge department or the key carbon discharge department is often a core enterprise or a tap enterprise in a region, the pollution discharge amount or the carbon discharge amount is often determined by the production property of the key enterprise or the tap enterprise, and the enterprise is forced to stop production according to a simple integral emission index, so that the enterprise is encouraged to perform new and old kinetic energy conversion to gradually replace the index control mode of the past, new energy in the new and old kinetic energy conversion is represented in the enterprise production, the new technology is actually used for replacing the old technology, the new production line is used for replacing the old production line, but the process is not the direct replacement of the old production line by the new production line, but is determined by the process of updating enterprise equipment and technology, and meanwhile, the organization production of the new and old production lines becomes the normal state of a plurality of key emission enterprises. Under the normal state, enterprises may prefer to choose the traditional production line to organize production without reasonable monitoring and index control means, because the traditional production line has high pollutant or carbon emission, but the production technology is mature, the productivity is high, and many links such as raw material cost and pollution control cost are lower than those of a new production line, so that the traditional production line is more beneficial to the short term of enterprises.
Therefore, when monitoring and operation control are carried out on the key pollution discharge production place or the key carbon emission production place based on environmental monitoring and index data processing, only the use of a new production line with low emission and an old production line with high emission is reasonably considered and planned, and the emission of the production place to the environment can be controlled on the basis that the production process of the production place is not obviously influenced.
Because the emission data of a system emission data acquisition unit (sensor) for monitoring and running control on an important pollution discharge production place or an important carbon emission production place based on environmental monitoring and index data processing in the prior art cannot be acquired according to production lines with different emission amounts of the production place, and an emission data analysis processing unit (system platform) cannot reasonably establish and calculate emission indexes according to the production lines with different emission amounts of the production place, how to establish new environmental monitoring hardware and software platforms by utilizing the existing monitoring, sensing and data communication technology, and reasonably acquire environmental and production data parameters according to the emission characteristics of the production place, and scientifically calculate and allocate the emission indexes is a new technical problem, so that environmental monitoring and running control of the production lines based on different emission amounts is realized technically.

Detailed Description
The technical solutions 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.
Examples
Referring to fig. 1, fig. 1 is a schematic diagram of an environmental monitoring system according to the present embodiment. The environmental monitoring system of the present embodiment is used for monitoring specific emissions in a production site and performing operation control, and is a new environmental monitoring hardware and software platform established by a series of monitoring, sensing and data communication technologies, and in order to implement basic monitoring and control functions, the environmental monitoring system of the present embodiment includes:
and the emission data acquisition unit is used for acquiring emission data of a production line of the production place. In particular, the emission data acquisition unit may comprise various types of known sensors for monitoring pollutant emissions, installed in the production line of the production site.
And the emission data analysis 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 aiming at the production process of the production place. The emission data analysis processing unit is at least installed at the monitoring end, but more preferably, the emission data analysis processing unit is installed at both the monitoring end and the production management end, so that the monitoring control department can conveniently grasp the emission dynamics, and the production place management side can conveniently grasp the emission dynamics.
And the operation control unit is used for controlling 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 be arranged in various modes according to different control conditions or policy conditions of different areas, the most direct mode is that the operation control unit is arranged in a production place and can directly perform interference control on the production process of the production place, or the operation control unit is arranged at an energy power management end, and energy control is performed through linkage of related departments, such as suspending supply of water, electricity, fuel gas and the like, so that the production process of the production place is indirectly interfered, and the two modes are all the prior art and are not described too much.
Compared with the current method of setting limits on the overall emission adopted when monitoring and interventional control are carried out on key pollution discharge production sites or key carbon emission production sites, the embodiment realizes different control processing modes and different technical effects through the establishment of new hardware and software platforms.
Specifically, the environmental monitoring system of the present embodiment further includes a production information interaction unit for communicating with the emission data analysis processing unit and providing production plan data to the emission data analysis processing unit. And, unlike the previous similar system, the emission data acquisition unit of this embodiment acquires 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 technology, it is easy to understand that the high emission production line is a production mode that is more willing to be adopted in a short period in an autonomous decision of the production site, and the low emission production line is an effective emission reduction production mode that a supervisor more hopes to be adopted in the production site.
The technical object of the present embodiment is achieved by the principle that the emission data analysis processing unit allocates emission indexes according to production plan data provided by the production information interaction unit, determines an emission upper limit of the high emission production line and an emission lower limit of the low emission production line in a monitoring control period, updates accumulated emission data of the high emission production line and accumulated emission data of the low emission production line in the monitoring control period in real time, calculates whether remaining time in the monitoring control period is enough to meet the emission indexes in real time according to the accumulated emission data and the emission indexes, generates a control instruction for a production process of a production place according to a calculation result, and controls the production process of the production place through the operation control unit.
The production information interaction unit is an independent information interaction system (such as an APP program) which needs to be installed at a production management end at present, but for a long-term stable monitoring object, a production management system (an MES platform and the like) which is directly accessed to a production place through the expansion of a program can be considered later.
Although not particularly limited to the type of production site of interest, one skilled in the art will be able to implement the above-described monitoring and measuring (the invention will be described by way of example below) in a manner that will occur to those of skill in the art based on the current industry characteristics. According to the principle introduced above, the emission data acquisition unit can acquire the emission data of the high emission production line and the emission data of the low emission production line of the production site at the same time, the production information interaction unit is introduced to provide the production plan data for the emission data analysis processing unit, the emission indexes can be flexibly distributed to the production site by the monitoring control department 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 one monitoring control period are determined, and then the real-time measurement and calculation are matched to determine whether the residual time in the monitoring control period is enough to meet the emission indexes, so that the production process of the production site can be timely interfered and controlled according to the measurement and calculation result.
Through the construction of the hardware and software platforms, environmental and production data parameters can be reasonably acquired according to the emission characteristics of production places, emission indexes are scientifically calculated and distributed, and therefore environmental monitoring and operation control of production lines based on different emission amounts are technically realized. The solution of the problem has social benefits besides the technical effect, because although the scheme of the embodiment still adopts intervention and control measures for production in the production place, compared with the prior method of setting the limit of the whole emission, the method can give a certain free decision right for production arrangement to the production place through scientific technical means, and achieves the purpose of guiding the reasonable emission reduction of the production place while ensuring the production.
The technical solution of the present embodiment is particularly suitable for monitoring pollutant emissions in a key production place, but the application of the system is not limited thereto, and carbon emissions are generally considered not to belong to pollutant emissions, but the technical solution of the present embodiment is obviously also applicable to monitoring carbon emissions in a key production place.
Examples
The present embodiment is based on the environmental monitoring system of embodiment 1 by way of example only, and provides a monitoring method adopted by the environmental monitoring system, and at least the method for establishing data in the monitoring method provided by the present embodiment can be adjusted or changed due to different production and operation types, different product types and different pollutant emission types of key production sites in different areas, namely: the present embodiment provides a typical but non-limiting solution with a relatively high application range.
Specifically, following the monitoring principle already described in example 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 the high emission production line and an emission lower limit of the low emission production line in a monitoring control period;
s2, simultaneously collecting emission data of at least one high emission production line and emission data of at least one low emission production line in a production place by an emission data collecting 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 steps mentioned in this embodiment, the emission data analysis processing unit distributes emission indexes according to the production plan data provided by the production information interaction unit, and the calculation mode for determining the emission upper limit of the high emission production line and the emission lower limit of the low emission production line in one monitoring control period may be:
Q H =M·A%·P H ；
Q L =M·B%·P L ；
wherein,,
Q H to monitor the emission index assigned to the high emission line during the control period, Q L An emission index assigned to the low emission production line for the monitoring control period;
m is the total production plan amount in the monitoring control period;
a% is a production schedule amount duty ratio allocated to a high emission production line in a monitoring control period, B% is a production schedule amount duty ratio allocated to a low emission production line in a monitoring control period, a% +b% =100%;
P H theoretical unit product emission value, P, for high emission production line L Is the theoretical unit product emission value of the low emission production line.
Verifying a production site's unit emission value from a product is currently a common way of accounting or predicting, for example, for a high emission foundry production site, the theoretical emission value per ton of castings.
Further, in the environmental monitoring system described in embodiment 1 and the above steps of this embodiment, the emission data collection unit may collect and calculate at least the real-time accumulated emission data Q of the high emission production line in real time H real Real-time accumulated emission data Q of the low emission production line L real Measured emission value P per unit time of the high emission production line H real Measured emission value per unit time P of the low emission production line L real 。
In this step of monitoring, if Q is present H real Exceeding Q H If the high emission line usage has exceeded the index limit, but this determination is obviously lagging and must be made at Q H real Has not exceeded Q H It is previously determined in advance whether the remaining time of the low emission production line in the monitoring control period is sufficient.
Therefore, further, in 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 surplus L =（Q L –Q L real ）/ P L real ；
Wherein,,
T surplus L Monitoring the remaining time in the control period for the low emission production line;
Q l real Accumulating emission data for a low emission production line in real time;
P l real Is the measured emission value per unit time of the low emission production line.
It should be noted in this step that P when not already enabled in the low emission line L real Obviously, 0 cannot be substituted, and the theoretical full negative of the low emission production line should be introducedThe charge unit time emission value (which has been obtained from previous production validations) is substituted.
Further, in the environmental monitoring system described in embodiment 1 and the above steps in this embodiment, it is calculated whether the remaining time in the monitoring control period is sufficient to complete the emission index by comparing the above-mentioned T Surplus L And comparing the theoretical remaining time in the monitoring control period. Specifically, the T is Surplus L Comparing with the theoretical remaining time in the monitoring control period if T Surplus L Having exceeded the theoretical remaining time in the monitoring control period, indicating that the minimum usage requirement of the low emission production line has not been 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 by the operation control unit, such as suspending the energy supply associated with the high emission production line. It is easy to understand that the theoretical remaining time is not limited to the natural time, and may be flexibly set according to actual production shifts, for example, for the case of single-shift production rather than three-shift production, the working time of one natural day is 8h or 480min rather than 24h.
Compared with the original monitoring system and the corresponding monitoring method, the improved monitoring system and the corresponding monitoring method provided by the embodiment are more scientific in operation, the data are established and adjusted more flexibly, the environment monitoring and operation control of the production line based on different emission can be technically realized through the construction of a simple software and hardware platform and the data parameter acquisition and calculation, the adopted emission data acquisition unit can acquire the emission data of the high emission production line and the emission data of the low emission production line of the production place at the same time, the emission plan data are provided for the emission data analysis processing unit through the introduction of the production information interaction unit, the emission indexes can be flexibly distributed according to the production plan data provided in advance, the emission upper limit and the emission lower limit of the low emission production line of the high emission production line in one monitoring control period can be determined, whether the residual time in the monitoring control period is enough to meet the emission indexes can be calculated in real time, the control instruction aiming at the production process of the production place can be generated according to the calculation result, and the production process of the production place can be controlled through the operation control unit, compared with the whole emission data adopted when the monitoring and intervention control is carried out on the important pollution discharge production place or the important carbon emission production place at present, the production place can be reasonably distributed according to the method of the production place at the basis of a certain free arrangement, and the production place can be reasonably ensured by means of ensuring the production place.
In addition, the monitoring system provided by the embodiment also fully considers the flexibility of the production plan of the production place, the production management end is further allowed to initiate the production plan changing application through the production information interaction unit in the monitoring control period through the application-approval program of the system, and the emission index data can be updated after the approval of the system is confirmed, so that the monitoring control process is carried out according to the updated emission index, and convenience is further provided for the production place.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
