Description

Technical Field

[0001] This invention relates to the field of hardware technology for energy consumption metering and carbon emission reduction accounting, specifically to a reliable metering system and method for carbon accounting of electrical equipment. Background Technology

[0002] With the advancement of the global dual-carbon strategy, the demand for carbon emission reduction accounting and carbon asset management for electrical equipment in various sectors has seen explosive growth. In particular, the restart of China's Certified Emission Reduction (CCER) mechanism has imposed extremely stringent legal requirements on the authenticity, traceability, and immutability of data for carbon emission reduction projects of electrical equipment.

[0003] Existing carbon accounting technologies for electrical equipment generally suffer from the following fundamental flaws: 1. Single-channel sampling or heterogeneous sampling methods are often used, resulting in inconsistent timing between the energy consumption of a single device and the total energy consumption of the loop, leading to significant data deviation. 2. Data verification relies on software algorithms, which can be bypassed or tampered with. 3. Carbon accounting parameters are stored in erasable and rewritable memory and can be modified during runtime; 4. The carbon accounting process relies on a central processing unit and software algorithms, making it susceptible to interference; 5. The system is highly dependent on network and cloud services; it cannot function properly when the network is down or the main power supply is faulty. 6. Data storage relies on software encryption, which is not secure enough.

[0004] Currently, the field of carbon accounting for electrical equipment lacks a fundamental core architecture that is physically implemented, fully reliable, available offline, tamper-proof, and directly supports compliance certification. All existing technologies fail to fundamentally solve the problems of carbon data authenticity and compliance, severely hindering the healthy development of the carbon emission reduction market. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned defects of the prior art and provide a reliable measurement system and method for carbon accounting of electrical equipment. It constructs a unique and reliable underlying architecture for carbon accounting of electrical equipment from the physical level, realizes the reliability, traceability and immutability of carbon data from collection to storage, and meets the strict requirements of national carbon emission reduction accounting standards and CCER project review.

[0006] The technical solution of the present invention is as follows: A reliable metering system for carbon accounting of electrical equipment includes a single synchronous clock hardware, dual-channel synchronous sampling hardware, hardware closed-loop verification hardware, parameter pre-setting and solidification hardware, carbon accounting hardware computing unit, native reliable storage hardware, offline autonomous hardware, and communication interface.

[0007] The single source clock hardware is electrically connected to the two sampling channels of the dual-channel synchronous sampling hardware to provide the same clock signal to the two sampling channels, ensuring that the sampling timing of the two channels is consistent.

[0008] The dual-channel synchronous sampling hardware includes a first sampling channel and a second sampling channel. The first sampling channel is used to collect the energy consumption signal of a single electrical device, and the second sampling channel is used to collect the total energy consumption signal of the circuit. The two sampling channels operate synchronously under the same clock signal, with the same sampling period, trigger time, and sampling accuracy.

[0009] The input terminals of the hardware closed-loop verification hardware are electrically connected to the output terminals of the two sampling channels, and the output terminals are electrically connected to the input terminals of the native trusted storage hardware. The hardware closed-loop verification hardware is a pure hardware comparison circuit that performs real-time comparison of the two acquired signals. If the comparison fails, data output to the native trusted storage hardware is prohibited.

[0010] The parameter pre-setting hardware is electrically connected to the carbon accounting hardware computing unit and is used to store carbon accounting parameters such as carbon emission factors, accounting coefficients, and baseline electricity consumption parameters. The parameter pre-setting hardware is a one-time programmable memory; once the parameters are written, they are in a permanent read-only state, without erase, rewrite, or debugging interfaces.

[0011] The carbon accounting hardware computing unit is electrically connected to native trusted storage hardware and uses a combination of hardware multipliers and adders to perform pure hardware calculations of carbon emissions based on carbon accounting parameters, without the intervention of software algorithms.

[0012] Native trusted storage hardware has a built-in hardware verification generation module that automatically generates a hardware verification value when data is written, and stores the collected data, verification result, hardware unique identifier, timestamp, and hardware verification value together. Any data modification will result in a hardware verification value mismatch.

[0013] The offline autonomous hardware is electrically connected to each of the aforementioned hardware components, including energy storage elements and an automatic power switching circuit. When the main power supply is normal, it supplies power to the system and charges the energy storage elements; when the main power supply fails, it automatically switches to power supply from the energy storage elements to maintain normal system operation.

[0014] The communication interface is electrically connected to the native trusted storage hardware, and only supports data upload and time synchronization operations. It does not support data modification, parameter writing, or storage area erasure operations.

[0015] This invention is applicable to carbon accounting for all electrical equipment, including but not limited to lighting equipment, air conditioning equipment, fans and pumps, industrial motors, charging piles, energy storage equipment, office equipment, and household appliances.

[0016] The technical solution of this invention fully complies with the mandatory requirements of the "Guidelines for Carbon Emission Accounting of Public Institutions" (JS / T 303-2026) and all subsequent revisions regarding data quality traceability, authenticity of measurement data, consistency of accounting parameters, traceability of accounting process, and offline operation. The generated carbon data can be directly used for carbon emission accounting, reporting, and carbon asset trading of various electrical equipment.

[0017] A reliable measurement method for carbon accounting of electrical equipment includes the following steps: S1: The single-source clock hardware outputs the same clock signal to the two sampling channels of the dual-channel synchronous sampling hardware; S2: The first sampling channel collects the energy consumption signal of a single electrical device, and the second sampling channel collects the total energy consumption signal of the circuit. The two channels are synchronously collected under the same clock signal. S3: Hardware closed-loop verification hardware performs real-time comparison of the two acquired signals, including instantaneous value comparison and continuous period consistency comparison. S4: If the comparison fails, the hardware closed-loop verification hardware will prohibit data output to the native trusted storage hardware; S5: If the comparison passes, the collected data will be associated with the hardware unique identifier, timestamp, and hardware check value and then written to the native trusted storage hardware. S6: The carbon accounting hardware computing unit calls the carbon accounting parameters stored in the pre-fixed hardware to complete the pure hardware calculation of carbon emissions; S7: Write carbon accounting results to native trusted storage hardware; S8: When the network is normal, data is uploaded through the communication interface; when the network is abnormal, the offline autonomous hardware maintains the system operation and stores the data locally. S9: After the network is restored, perform offline incremental data synchronization without modifying the stored data. Beneficial effects
