Description

Technical Field

[0001] This invention relates to the technical field of carbon metering modules, and in particular to a high-precision carbon metering module. Background Technology

[0002] With the continued advancement of the global carbon neutrality strategy, energy conservation and emission reduction have become core development goals across all sectors of society. End-user electricity consumers have an increasingly urgent need for the quantification, monitoring, and management of carbon emissions during electricity consumption. Currently, some electricity products on the market integrate electricity metering and carbon emission estimation functions. These products generally employ a fixed carbon emission factor calculation method, meaning a single carbon emission factor is pre-fixed within the device. The cumulative electricity consumption obtained through metering is multiplied by this fixed factor to estimate the user's cumulative carbon emissions from electricity consumption.

[0003] Currently, existing technologies use fixed-coefficient estimation methods in practical applications, resulting in a significant discrepancy between the calculated results and the actual carbon emissions generated by users' electricity consumption behavior. This fails to provide valuable reference data for users' energy-saving and carbon-reduction activities, and the data has poor reliability and traceability.

[0004] For example, the existing technology announcement number CN118425608A patent relates to an electric carbon metering terminal, which includes an energy metering module, a carbon emission metering module, a power detection module, a key display module, a communication module, and a main control module.

[0005] Existing technologies have been found to have poor structural optimization for acquiring voltage and current, and poor intelligent performance based on power source switching factors, thus reducing their effectiveness. Summary of the Invention

[0006] To address the aforementioned technical issues, this invention provides a high-precision carbon metering module that solves the problem from three dimensions: improving the accuracy of front-end electricity metering, adapting to core dynamic carbon emission factors, and optimizing carbon metering algorithms. This module achieves real-time, high-precision, and traceable metering of carbon emissions on the electricity consumption side, while also improving environmental adaptability and functional scalability.

[0007] The present invention provides a high-precision carbon metering module, comprising an energy metering unit, a dynamic carbon emission factor processing unit, a microprocessor and control unit, a carbon metering algorithm module, and a display and output unit; The electricity metering unit includes a sampling circuit and a digital filtering submodule; Sampling circuit: Employs a multi-channel synchronous sampling architecture; Digital filtering submodule: Built-in harmonic suppression algorithm to suppress harmonic interference under nonlinear loads and ensure metering accuracy under all working conditions; The power metering unit is directly connected to the AC power circuit under test to collect voltage and current signals in the circuit in real time, calculate and output instantaneous active power and cumulative power data; Dynamic carbon emission factor processing unit: electrically connected to the microprocessor and control unit, used for storing, updating and intelligently matching carbon emission factors, and outputting effective carbon emission factors that match the current operating conditions; Microprocessor and control unit: Electrically connected to the power metering unit, dynamic carbon emission factor processing unit, and display and output unit respectively, used to receive power data and effective carbon emission factors, schedule the operation of the carbon metering algorithm module, and coordinate the working timing and data interaction of the overall module; Carbon metering algorithm module: Embedded in the microprocessor and control unit, it is used to calculate the real-time carbon emission rate based on instantaneous active power and effective carbon emission factor, integrate and accumulate the real-time carbon emission rate based on the time dimension, and calculate and output the cumulative carbon emissions. Display and Output Unit: The display screen is electrically connected to the microprocessor and control unit to display metering data and support the external transmission of metering data. The power metering unit realizes the accuracy of power metering under all operating conditions, controlling the error of basic data from the source. Through the dynamic carbon emission factor processing unit, the time-sharing and zone-based dynamic adaptation of carbon emission factors is realized, so that the carbon metering calculation is fully matched with the real-time changes in the carbon emission intensity of the power grid. This upgrades carbon metering from rough estimation to scientific metering based on accurate data, improves the reliability of carbon metering data, avoids the problem of accuracy continuously decreasing over time due to fixed coefficients, and improves the metering accuracy throughout the product's entire life cycle. The solution addresses three dimensions: improving the accuracy of front-end electricity metering, adapting core dynamic carbon emission factors, and optimizing carbon metering algorithms. This enables real-time, high-precision, and traceable metering of carbon emissions on the electricity consumption side, while also enhancing environmental adaptability and functional scalability.

[0008] Preferably, the dynamic carbon emission factor processing unit includes a factor storage area, a factor input update interface, and a factor selection logic submodule; Factor storage area: Used to store at least one set of carbon emission factors, with a default carbon emission factor set, and also supports partitioned storage and retrieval of carbon emission factors for multiple time periods and regions; Factor input update interface: used to receive externally input carbon emission factor data and update the data in the factor storage area; Factor selection logic submodule: Built-in real-time clock, used to automatically match and output the effective carbon emission factor under the current operating conditions based on the current time, geographical location information or user configuration instructions.

[0009] Preferably, the calculation logic of the carbon metering algorithm module is as follows: Real-time carbon emission rate = instantaneous active power × current effective carbon emission factor ÷ 1000; Cumulative carbon emissions = ∑ (real-time carbon emission rate per unit time interval × unit time interval). The unit for real-time carbon emission rate is kgCO2 / h, the unit for instantaneous active power is W, the unit for current effective carbon emission factor is kgCO2 / kWh, and the unit for cumulative carbon emissions is kgCO2.

[0010] Preferably, the factor input update interface supports multiple data update modes: Data update mode one: manual input mode via device button combinations; Data update mode two: configuration update mode via Bluetooth or Wi-Fi communication interface to connect to the mobile APP; The third data update mode is an automatic update mode that connects to authoritative data sources through a network communication interface and automatically synchronizes with the real-time carbon emission factor data stream bound to the power grid region to which the module belongs.

[0011] Preferably, the display and output unit includes a display module and a communication interface submodule; Display module: An LCD screen used to display real-time power, cumulative electricity consumption, current effective carbon emission factor, real-time carbon emission rate, and cumulative carbon emissions, while simultaneously displaying the version information, update time, and effective period of the current carbon emission factor; Communication interface submodule: used to upload metering data to the host computer, cloud platform and smart home control system.

[0012] Preferably, it also includes a support assembly, a first housing, a second housing, a limiting block, a pin, an L-shaped part, and a groove; The power metering unit, the dynamic carbon emission factor processing unit, the microprocessor and control unit, the carbon metering algorithm module, and the display and output unit are respectively installed inside the first housing and the second housing; The second housing is plugged into and installed on the first housing; The limiting block is disposed on the inner sidewall of the second housing, and a guide slope is provided at the front end of the limiting block; The pin is slidably mounted on the first housing. The L-shaped part is set on the outer wall of the pin; The groove is set on the limiting block, and the groove corresponds to the position of the L-shaped part; A support assembly is installed on the first housing to provide elastic support for the pin. The front end of the second housing is inserted into the rear of the first housing. During the installation of the second housing, the limiting block moves, causing its front end to contact the L-shaped piece. As the second housing continues to be inserted and moved, the guide slope at the front end of the limiting block pushes the L-shaped piece, causing it to slide along the pin. When the second housing is fully inserted, the groove moves to the L-shaped piece, at which point the pin slides back to its original position through the support assembly, thus embedding the L-shaped piece into the groove and locking the first and second housings. When the second housing needs to be disassembled, the support assembly is pressed down to move the pin and the L-shaped piece. Once the L-shaped piece separates from the groove, the second housing can be slidably disassembled, improving the convenience of installation, removal, inspection, and maintenance of the second housing.

[0013] Preferably, the support assembly includes a cylinder, a limiting plate, a first spring, an internal threaded fitting, threads, and a top plate; The cylinder is mounted on the outer wall of the first housing, and the pin slides through the inside of the cylinder. The limiting plate is slidably installed inside the cylinder, and the limiting plate is set on the outer wall of the pin shaft; The first spring is fitted onto the outer wall of the pin; The thread is located on the outer wall of the pin. The internal threaded fitting is screwed onto the thread; The top plate is set at the top of the pin shaft; The top of the internal threaded assembly has a groove whose shape matches the top plate. A first spring provides elastic support to the limiting plate, which in turn provides elastic support to the pin. This allows the L-shaped part to be inserted into the groove and locked to the limiting block. When it is necessary to separate the L-shaped part from the groove, pressing the top plate causes it to slide along the pin, which in turn moves the L-shaped part, thus separating it from the groove and improving ease of operation. After the second housing and the first housing are installed, rotating the internal threaded assembly moves it toward the cylinder through the thread, thus supporting and limiting the sliding of the pin and preventing accidental pressing of the pin, improving the locking effect of the L-shaped part. When it is necessary to press the pin, rotating the internal threaded assembly toward the top plate causes the top plate to embed into the groove of the internal threaded assembly. At this time, the internal threaded assembly and the top plate form a whole, improving the ease of operation for personnel.

[0014] Preferably, it also includes a support base, a support rod, and a second spring; The support base is located on the inner wall of the second housing; The support rod is slidably mounted on the support base; The second spring is fitted onto the support rod. When the second housing is installed on the first housing, the support rod contacts the outer wall of the first housing and compresses the second spring. When the L-shaped part separates from the groove, the second spring pushes the support seat, causing the support seat to move the second housing, thereby automatically separating the second housing from the first housing and reducing the difficulty of disassembling the second housing.

[0015] Preferably, it also includes an exhaust port, an air intake channel, a magnetic protective mesh, and a fan; The vent is located on the second housing; The air intake passage is located at the rear end of the outer side wall of the second housing; The magnetic protective net is installed at the air intake opening; The fan is installed inside the air intake channel. When the metering module is running, the fan blows air into the second housing, and outdoor air enters the second housing and is discharged out through the exhaust port, thereby dissipating heat and cooling the second housing. The opening of the air intake channel is blocked by a magnetic protective net to improve the dust prevention effect. The magnetic protective net is also installed magnetically to improve the convenience of disassembling and cleaning the magnetic protective net.

[0016] Preferably, it also includes a mounting bracket, a guide, an internal threaded seat, and screws; The mounting bracket has an opening, and the first housing extends into the opening of the mounting bracket; The guide components are mounted on the outer wall of the mounting bracket; The internal thread seat is located on the outer side wall of the first housing; The screw passes through the mounting bracket and is screwed onto the internal thread seat; the first housing is slidably installed at the opening of the mounting bracket, and then the screw passes through the mounting bracket and is screwed onto the internal thread seat, thereby fixing the first housing on the mounting bracket. The first housing is slidably guided by the guide member to improve the stability of the installation operation of the first housing. Then the mounting bracket is fixedly installed to achieve the positioning of the first housing.

[0017] Compared with existing technologies, the beneficial effects of this invention are as follows: It achieves accurate electricity metering under all operating conditions through the electricity metering unit, controls basic data errors from the source, and realizes time-sharing and zone-based dynamic adaptation of carbon emission factors through the dynamic carbon emission factor processing unit, so that the carbon metering calculation is fully matched with the real-time carbon emission intensity changes of the power grid, upgrades carbon metering from rough estimation to scientific metering based on accurate data, improves the reliability of carbon metering data, avoids the problem of accuracy continuously decreasing over time due to fixed coefficients, improves metering accuracy throughout the product's entire life cycle, improves the convenience of loading, unloading, inspection and maintenance, and avoids accidental disassembly.

The power metering unit, the dynamic carbon emission factor processing unit, the microprocessor and control unit, the carbon metering algorithm module, and the display and output unit are respectively installed inside the first housing 101 and the second housing 102; The second housing 102 is plugged into and installed on the first housing 101; The limiting block 103 is disposed on the inner sidewall of the second housing 102, and the front end of the limiting block 103 is provided with a guide slope. The pin 104 is slidably mounted on the first housing 101; L-shaped part 105 is disposed on the outer wall of pin 104; The groove 106 is provided on the limiting block 103, and the groove 106 corresponds to the position of the L-shaped part 105; The support assembly is mounted on the first housing 101 and is used to provide elastic support for the pin 104. The support assembly includes a cylinder 201, a limiting plate 202, a first spring 203, an internal threaded fitting 204, a thread 205, and a top plate 206; The cylinder 201 is mounted on the outer wall of the first housing 101, and the pin 104 slides through the inside of the cylinder 201. The limiting plate 202 is slidably installed inside the cylinder 201, and the limiting plate 202 is set on the outer wall of the pin 104; The first spring 203 is fitted onto the outer wall of the pin 104; Thread 205 is provided on the outer wall of pin 104; The internal threaded fitting 204 is screwed onto the thread 205; Top plate 206 is located at the top of pin 104; The top of the internal threaded fitting 204 is provided with a groove, the shape of which matches the top plate 206; It also includes a support base 301, a support rod 302, and a second spring 303; The support base 301 is disposed on the inner side wall of the second housing 102; The support rod 302 is slidably mounted on the support base 301; The second spring 303 is fitted onto the support rod 302; It also includes an exhaust port 401, an air intake channel 402, a magnetic protective net 403, and a fan 404; Vent 401 is provided on the second housing 102; The air intake passage 402 is located at the rear end of the outer side wall of the second housing 102; The magnetic protective net 403 is installed at the opening of the air intake channel 402; Fan 404 is installed inside air intake channel 402; It also includes a mounting bracket 501, a guide 502, an internal thread seat 503, and a screw 504; The mounting bracket 501 has an opening, and the first housing 101 extends into the opening of the mounting bracket 501; Guide component 502 is disposed on the outer wall of mounting bracket 501; The internal thread seat 503 is disposed on the outer side wall of the first housing 101; Screw 504 passes through mounting bracket 501 and is screwed onto internal thread seat 503; In this embodiment, the front end of the second housing 102 is inserted and installed at the rear of the first housing 101. During the installation of the second housing 102, the limiting block 103 moves, causing the front end of the limiting block 103 to contact the L-shaped part 105. As the second housing 102 continues to be inserted and moved, the guide slope at the front end of the limiting block 103 pushes the L-shaped part 105, causing the L-shaped part 105 to drive the pin 104 to slide.

When it is necessary to separate the L-shaped part 105 from the groove 106, pressing the top plate 206 causes the pin 104 to slide, which in turn moves the L-shaped part 105, separating it from the groove 106 and improving operational convenience. After the second housing 102 and the first housing 101 are installed, rotating the internal threaded fitting 204 allows the internal threaded fitting 204 to...

When it is necessary to press the pin 104, the internal threaded part 204 is rotated and moved toward the top plate 206, so that the top plate 206 is embedded in the groove of the internal threaded part 204. At this time, the internal threaded part 204 and the top plate 206 form a whole, improving the convenience of personnel pressing operation.

[0023] Example 3 The power metering unit is directly connected to a 220V / 50Hz household AC power supply circuit. The load under test is connected to the module output terminal.

The default factor area is preset with the national average grid carbon emission factor of 0.5810 kg CO2 / kWh published by the State Grid Corporation of China. The time-of-use factor zone can store carbon emission factors corresponding to peak, flat and valley periods, adapting to the time-of-use electricity price and the time-of-use carbon emission intensity of the power grid in the user's region. The regional factor zone can store the annual / monthly average carbon emission factors released by the power grids of all provinces and cities across the country.
