[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides an integrated device for zero-carbon electricity metering and carbon emission monitoring.

[0021] Please refer to the following: Figure 1 In one embodiment of the present invention, the integrated zero-carbon electricity metering and carbon emission monitoring device includes a terminal body 1, on which a main control circuit board, a human-machine interaction module, and wiring terminals 2 are disposed. The main control circuit board integrates an electricity metering module, a carbon emission monitoring module, a main control module, and a storage module. The electricity metering module is used to collect time-of-use electricity data and output it to the carbon emission monitoring module to complete the single static factor carbon emission calculation. The device also includes: The carbon factor access module is used to connect to multiple carbon factor data sources such as the power grid, cloud, and local gateway in parallel, so as to realize the real-time reception, caching and distribution of dynamic carbon factor messages. A multi-region storage module is used to partition and cache the time-sharing dynamic carbon factor and multi-account standard-specific coefficients in different regions. The verification module is used to verify the integrity and source legitimacy of externally sent carbon factor data packets.

[0022] In this invention, the terminal body 1 is the main device of the carbon meter.

[0023] This invention establishes a multi-channel dynamic carbon factor transmission link connecting the power grid, cloud, and local areas by adding a carbon factor access module, a multi-region storage module, and a verification module. This solves the defects of fragmented upstream data source protocols and lack of backup for data disconnection, significantly improving the cross-regional and multi-scenario adaptability of the carbon metering terminal. The carbon accounting data has complete traceability and reliable verification capabilities, meeting carbon verification standards.

[0024] The carbon factor access module is electrically connected to the microprocessor of the main control module, and includes a dual-channel isolated RS485 communication subunit and an independent wireless radio frequency communication subunit. The dual-channel isolated RS485 communication subunit is respectively connected to the plant edge energy carbon gateway and the provincial power grid carbon factor service terminal, and the wireless radio frequency communication subunit is directly connected to the official carbon factor service platform in the cloud. This enables parallel access of multiple data sources, automatic switching of link failures, and the construction of a dynamic multi-channel transmission hardware link for carbon factors. The multi-region storage module is mounted on the external data bus of the microprocessor of the main control module and includes an extended non-volatile Flash memory chip. The chip partitions the storage of time-sharing dynamic carbon factor databases for various regions across the country, carbon emission coefficient databases for self-owned units, and dedicated factor parameter sets for multi-accounting standards. It supports local offline caching of more than 7 days of time-sharing dynamic factor data as a backup data source for carbon accounting during network disconnection periods. Furthermore, the partitioned storage includes dedicated factor libraries for various accounting standards, including: domestic regional power grid factors (GB / T32150 specific), ISO14064 international default power factors, CBAM EU accounting benchmark factors, and CCER / carbon inclusive green electricity deduction coefficients; it also stores time-sharing dynamic regional factors for all provinces in China, taking into account cross-regional switching needs and solving the underlying deficiency of lacking supporting parameters for different regions and standards. The verification module communicates bidirectionally with the carbon factor access module and the multi-region storage module, and has built-in national cryptographic encryption verification algorithm hardware logic; it performs integrity and source legality verification on the dynamic carbon factor data packets issued by the upstream platform to prevent factor data tampering and ensure the reliability of the underlying data source for carbon accounting; In this invention, the storage module is used to store various types of acquired data, and also includes an Internet of Things (IoT) module for transmitting power data and carbon emission data to the backend, cloud, etc.

[0025] This invention integrates a high-precision power metering module and a carbon emission monitoring module. The power metering module employs advanced electromagnetic induction or electronic metering technology to accurately measure energy consumption and transmission within the power system. The carbon emission monitoring module can accurately calculate carbon emissions by analyzing fuel composition, combustion processes, and chemical reactions related to power production, combined with real-time power production data. Simultaneously, the device possesses data processing and transmission capabilities, uploading power metering and carbon emission data to a management platform in real time, providing data support for zero-carbon power management.

[0026] As a preferred embodiment, the integrated zero-carbon electricity metering and carbon emission monitoring device further includes a multi-power source anti-interference module, which is used to correct the power sampling deviation caused by industrial electromagnetic interference and identify the multi-power source mixed power supply topology to complete a reproducible carbon emission fair allocation calculation.

[0027] Specifically, the multi-power source anti-interference module includes a carbon flow allocation calculation module, a digital anti-interference compensation calculation module, a multi-branch load topology splitting module, and an abnormal data timing repair module.

[0028] The carbon flow allocation calculation module is embedded in the microprocessor of the main control module. It has built-in Shapley value (Shapley fair allocation algorithm) fair allocation algorithm sub-logic and multi-power load identification sub-logic. It automatically identifies four types of mixed power supply topologies: external grid power, distributed photovoltaic, energy storage charging and discharging, and self-provided thermal power. It distinguishes between photovoltaic self-generation and self-consumption zero carbon deduction, energy storage bidirectional carbon responsibility allocation, and public bus loss carbon allocation, and outputs complete and reproducible unit carbon emission details data.

[0029] Among them, the Shapley fair allocation algorithm sub-logic is used to split the carbon emissions of the common bus loss based on the marginal electricity contribution of each power branch, so as to realize fair and reproducible allocation calculation of carbon emission responsibility under mixed operating conditions of multiple power sources.

[0030] The digital anti-interference compensation calculation module is linked with the metering ASIC chip and adopts 16 times oversampling and majority voting filtering logic to automatically identify and eliminate instantaneous abnormal power pulses generated by motor start-up and shutdown and electric arc impact; it is equipped with a harmonic distortion metering compensation sub-algorithm to correct the power metering deviation caused by harmonic interference in real time, and avoid carbon emission measurement jump distortion from the source.

[0031] The multi-branch load topology splitting module completes load topology AI recognition based on the time-sharing power curve of the entire branch. For old factory topologies with shared transformers and cross-power supply, it automatically splits the power consumption and corresponding carbon emissions of each independent production unit, solving the technical defects of fuzzy metering boundaries and inability to distinguish carbon consumption of multiple branches.

[0032] The abnormal data time series repair module marks abnormal carbon emission sampling points caused by electromagnetic interference in real time, and completes linear interpolation repair based on the preceding and following time series electrical energy data and time-division carbon factor parameters to ensure the integrity and effectiveness of the continuous time series carbon ledger and meet the carbon verification original data retention specifications.

[0033] In this embodiment, the human-computer interaction module includes a display screen 10 and a button module, which are disposed on the front of the terminal body 1.

[0034] The display screen 10 is used to output and display metered data such as electrical energy and carbon emissions.

[0035] The button module is used to realize basic functions such as data page turning, equipment parameter query, and fault alarm reset, as well as extended functions such as accounting standard switching, regional dynamic factor selection, and local export of time-series carbon ledger.

[0036] Please refer to the following: Figure 2 and Figure 7 In this embodiment, the integrated zero-carbon electricity metering and carbon emission monitoring device also includes a protective cover structure 3. Locking sleeves 12 are installed on both sides of the terminal body 1. When the protective cover structure 3 is installed with the locking sleeves 12, the protective cover structure 3 covers the outside of the wiring terminal 2.

[0037] Terminal 2 enables electrical connection and mechanical fixation of external cables to the internal circuit of the terminal. After each line 6 is installed with terminal 2, a protective cover structure 3 is installed on the outside of terminal 2 to protect it, forming a physical insulation barrier to prevent personnel from directly touching the live terminals and achieve electric shock safety protection; it can also isolate dust, water vapor, oil and small foreign objects to prevent terminal oxidation, phase-to-phase short circuits and loose wiring.

[0038] The protective cover structure 3 is a transparent plastic cover.

[0039] Please see Figure 3 and Figure 4 In this embodiment, the top and bottom of the back of the terminal body 1 are provided with wiring terminals 2, and there are two protective cover structures 3, which are respectively covered on the outside of the two wiring terminals 2.

[0040] Setting the wiring terminals 2 on the upper and lower sides of the back of the terminal body 1 is beneficial for arranging the wiring terminals 2; Among them, the bottom wiring terminal 2 of the terminal body 1 is for the high-voltage terminal group to connect to the three-phase voltage, the current metering circuit of the transformer, and output the power verification pulse, etc., while the wiring terminal 2 at the top of the terminal body 1 provides the instrument auxiliary power supply, remote communication, and switch signal input / output interface for the low-voltage terminal group.

[0041] Please see Figure 3 As a preferred embodiment, the top and bottom of the back of the terminal body 1 are symmetrically provided with positioning sleeves 11. When the protective cover structure 3 is installed with the positioning sleeves 11, the protective cover structure 3 is suspended on one side of the terminal block 2. The protective cover structure 3 includes a main cover 31, a driven cover 32 and a connecting pin 33. The main cover 31 and the driven cover 32 are detachably connected by the connecting pin 33. The main cover 31 and the driven cover 32 are symmetrically provided with arc-shaped holes 301 at corresponding positions. Anti-slip pads 302 are installed in the arc-shaped holes 301.

[0042] Since multiple wires 6 are usually installed on the terminal 2 of the terminal body 1, during installation, the operator usually holds the wire 6 and inserts the exposed copper wire at the front end of the wire 6 into the wiring hole of the terminal 2, keeping the copper wire inserted into the terminal 2. Then, the other hand needs to use a tool to tighten the screw on the terminal 2, so that the screw is pressed against the copper wire of the wire 6, making it firmly connected to the copper conductive pad inside the terminal 2. That is, the operator holds the wire to keep it inserted into the terminal 2, and uses a tool to tighten the screw with the other hand, which is quite troublesome. In this invention, the protective cover structure 3 is configured as a main cover 31 and a driven cover 32, and connected by a connecting pin 33. When the main cover 31 and the driven cover 32 are closed, the two symmetrically arranged arc-shaped holes 301 form a circular hole. When installing each line 6, taking the bottom terminal 2 as an example, first leave some gap between the main cover 31 and the driven cover 32 so that each line 6 can pass through the circular through hole formed by the two sets of arc holes 301. The through hole has sufficient wire length. When the protective cover structure 3 and the positioning sleeve 11 are installed, the copper wire at the top of the line 6 can be inserted into the terminal 2. Multiple wires 6 can be passed sequentially through their corresponding circular holes. Then, connecting pins 33 are used to connect the main cover 31 and the driven cover 32, clamping each wire 6 in the arc-shaped holes 301. Next, the protective cover structure 3 is lifted, causing each wire 6 to be inserted into its corresponding terminal block 2. Simultaneously, the end of the connecting pin 33 can be inserted into the positioning sleeve 11 to support the protective cover structure 3. At this point, a gap is left between the protective cover structure 3 and the terminal block 2. Figure 7 In step (a), it can be observed whether the line 6 is inserted into the terminal 2. The operator can adjust the line 6 that is not properly inserted. At this time, the protective cover structure 3 can be used to support each line 6. The operator does not need to hold the line 6 and avoids the line 6 from coming out of the terminal 2. The operator only needs to tighten the corresponding screws in sequence, which simplifies the installation steps of each line 6 and terminal 2. After all the screws are tightened, the main cover 31 and the driven cover 32 can be loosened. At this time, the operator can pull down the line 6 in sequence to check whether it is fixed firmly.

[0043] Then, the protective cover structure 3 can be pushed up to completely cover the outside of the terminal 2, thus protecting the terminal 2. Then, the connecting pin 33 can be used to make the main cover 31 and the driven cover 32 close together again and clamp the line 6, thereby providing auxiliary support for the line 6 and improving the stability of the connection between the line 6 and the terminal 2.

[0044] The connection operation between each line 6 and the top terminal 2 is carried out in the same way.

[0045] The anti-slip pad 302 is installed inside the arc-shaped hole 301 to improve the stability of clamping the circuit 6 and protect the circuit 6 from wear; the anti-slip pad 302 can be a rubber pad, silicone pad, or leather, etc.

[0046] Please see Figure 3 As an optional embodiment, the main cover 31 is provided with a connecting ear 311 on its side, the driven cover 32 is provided with a fixing ear 312 on its side, and one end of the connecting pin 33 passes through the connecting ear 311 and the fixing ear 312 in sequence and is threadedly connected to the fixing ear 312.

[0047] The connection and separation of the main cover 31 and the driven cover 32 can be achieved by turning the connecting pin 33, which is simple to operate.

[0048] The connecting ear 311 and the fixing ear 312 are respectively provided with fixing holes, and the fixing ear 312 is fitted with a nut in the corresponding fixing hole. The connecting pin 33 passes through the connecting ear 311 and the fixing ear 312 and is threadedly connected to the nut. After the threaded connection, the connecting ear 311 is located between the fixing ear 312 and the end cap 333 of the connecting pin 33.

[0049] In this embodiment, preferably, the connecting pin 33 is threaded at both the end near the end cap 333 and the end away from the end cap 333; the locking sleeve 12 is embedded with a threaded bushing. When the protective cover structure 3 is completely covered on the terminal 2, the locking sleeve 12, the connecting ear 311 and the fixing ear 312 are aligned. The connecting pin 33 passes through the connecting ear 311 and the fixing ear 312 in sequence and then abuts against the locking sleeve 12. Then, the connecting pin 33 is turned so that the threads at both ends of the connecting pin 33 are threadedly connected to the locking sleeve 12 and the fixing ear 312 in sequence, thereby realizing the connection between the main cover 31 and the driven cover 32, as well as the installation connection between the protective cover structure 3 and the terminal body 1.

[0050] Of course, in other embodiments, an elastic block can be provided on the driven cover 32, and a slot can be provided on the locking sleeve 12. When the protective cover structure 3 is completely covered on the terminal 2, the elastic block on the driven cover 32 is inserted into the slot to realize the installation of the protective cover structure 3 and the terminal body 1.

[0051] Please see Figure 3 In this embodiment, the integrated zero-carbon electricity metering and carbon emission monitoring device also includes a buckle 4, which is detachably installed on the side of the terminal body 1 and is used to fix the terminal body 1 on the cabinet door 5.

[0052] The terminal body 1 is installed by opening a rectangular mounting hole 51 on the cabinet door 5 of the power distribution cabinet, and then using a buckle 4 to fix the terminal body 1 on the cabinet door 5. The display screen 10 and buttons on the terminal body 1 face outward from the cabinet door 5, which makes it convenient for staff to read data and operate the terminal body 1.

[0053] The wiring terminal 2 is located on the back of the terminal body 1. The terminal body 1 is installed on the cabinet door 5 to facilitate the connection of each line 6 to the wiring terminal 2.

[0054] Please see Figure 3 , Figure 4 and Figure 6 As an optional solution in this embodiment, the terminal body 1 has sliding grooves 101 on both sides. The buckle 4 includes a connecting block 41, a limiting piece 42 and a fixing member 43. The connecting block 41 is slidably connected to the sliding groove 101. The limiting piece 42 is installed on the connecting block 41. The fixing member 43 is used to connect the connecting block 41 and the terminal body 1. The front side of the terminal body 1 is provided with a boss 102.

[0055] The rectangular mounting hole 51 on the cabinet door 5 has a smaller opening size than the outer contour size of the boss 102, so that the terminal body 1 can be installed on the cabinet door 5 using the boss 102 and the buckle 4. Figure 7 (c) During installation, the back of the terminal body 1 is first passed through the rectangular mounting hole 51, so that the protrusion 102 fits against the outside of the cabinet door 5. Then, the buckle 4 is slid along the slide groove 101 until the connecting block 41 and the limiting piece 42 abut against the inside of the cabinet door 5. Then, the terminal body 1 and the connecting block 41 are connected by the fastener 43, thereby limiting the connecting block 41 along the direction of the slide groove 101, so that the terminal body 1 can be stably installed on the cabinet door 5.

[0056] Among them, the slide 101 is a T-shaped groove, and a T-shaped slider is provided on one side of the connecting block 41.

[0057] The rectangular mounting hole 51 on the cabinet door 5 is provided with a slot corresponding to the position of the positioning sleeve 11 and the locking sleeve 12 so that the positioning sleeve 11 can pass through smoothly.

[0058] As another optional solution in this embodiment, the buckle 4 is an L-shaped block with assembly holes on both sides. Threaded posts are set on both sides of the terminal body 1, and through holes are opened on the cabinet door 5. The assembly hole on one side of the L-shaped block is fitted onto the threaded post, and then tightened with a nut. At this time, the assembly hole on the other side of the L-shaped block is aligned with the through hole on the cabinet door 5, and then fixed with bolts and nuts.

[0059] Please see Figure 3 , Figure 5and Figure 6 As an optional solution in this embodiment, the fixing member 43 is a fixing block, and the fixing block has a fixing hole. When the connecting block 41 slides into the sliding groove 101, the fixing hole of the fixing member 43 is aligned with the assembly hole on the connecting block 41. The connecting pin 33 includes a first connecting shaft 331, a second connecting shaft 332, and an end cap 333. The first connecting shaft 331 connects the second connecting shaft 332 and the end cap 333. The diameter of the first connecting shaft 331 is larger than that of the second connecting shaft 332. Both the first connecting shaft 331 and the second connecting shaft 332 are provided with threaded surfaces.

[0060] When installing the terminal body 1, after passing the terminal body 1 through the rectangular mounting hole 51 on the cabinet door 5, the protrusion 102 fits against the outside of the cabinet door 5, and then the buckle 4 slides in along the slide groove 101, and the connecting block 41 and the limiting piece 42 abut against the inside of the cabinet door 5, and the fixing piece 43 fits against the locking sleeve 12, thus pre-installing the terminal body 1. Then, each line 6 is installed with the terminal 2 of the terminal body 1. After installation, the protective cover structure 3 is completely covered outside the terminal 2. At this time, the connecting ear 311, the fixing ear 312, the fixing member 43 and the locking sleeve 12 are aligned. The connecting pin 33 is passed through the connecting ear 311, the fixing ear 312, the fixing member 43 and the locking sleeve 12 in sequence. The thread on the first connecting shaft 331 is tightened with the nut on the fixing ear 312, and the thread on the second connecting shaft 332 is abutted with the threaded bushing in the locking sleeve 12. Then, the end cap 333 is turned so that the first connecting shaft 331 is threadedly connected with the nut on the fixing ear 312, and the second connecting shaft 332 is threadedly connected with the threaded bushing in the locking sleeve 12. After the threaded connection is completed, the first connecting shaft 331 abuts against the fixing member 43 and limits its position. This can realize the connection between the main cover 31 and the driven cover 32, and realize the limiting connection between the buckle 4 and the terminal body 1, thereby realizing the final installation of the terminal body 1 and the cabinet door 5.

[0061] Therefore, when the protective cover structure 3 is assembled with the positioning sleeve 11, it can clamp the line 6 and support each line 6, making it easy for the operator to tighten and lock the connection line 6. When the protective cover structure 3 is installed with the locking sleeve 12, it can protect the terminal 2. In the switching between the two functions, the buckle 4 can be limited to the terminal body 1, thus realizing the final installation of the terminal body 1 and the cabinet door 5.

[0062] The stepped hole structure inside the positioning sleeve 11 is adapted to the outer diameter of the first connecting shaft 331 and the second connecting shaft 332, and has two different inner diameters. After the connecting pin 33 is inserted into the positioning sleeve 11, the first connecting shaft 331 and the second connecting shaft 332 can fit against the inner hole wall of the positioning sleeve 11, so that the connecting pin 33 can be used to horizontally support the protective cover structure 3.

[0063] As another optional solution in this embodiment, the fixing member 43 is a screw, a through hole is provided on the connecting block 41, and nuts are pre-embedded on both sides of the terminal body 1; when the connecting block 41 and the limiting piece 42 abut against the inside of the cabinet door 5, the through hole on the connecting block 41 is aligned with the nut, and then the screw is tightened with the nut after passing through the through hole.

[0064] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
