Description

Technical Field

[0001] This utility model relates to the field of smart meter technology, and in particular to an installation structure and a smart meter. Background Technology

[0002] Traditional smart meters' core metering function is limited to collecting electrical parameters such as voltage, current, and power. Their calculation units' fixed energy metering algorithms cannot directly support carbon emission accounting. Some solutions achieve carbon metering through external carbon metering coprocessors, but this increases hardware costs by more than 30% and requires modifications to the meter structure. Another method achieves carbon metering by uploading electricity consumption data to a cloud server, but this method is affected by communication network latency, with real-time performance exceeding five seconds and the function failing when the network is down. With technological advancements, smart meters are gradually incorporating electricity consumption carbon metering functions. However, after the electricity consumption carbon metering data is generated, the original LCD screen cannot display the carbon metering-related data, which no longer meets the usage requirements of smart meters with built-in carbon metering functions.

[0029] Example 1

[0030] Reference Figures 1 to 3This is the first embodiment of the present invention. This embodiment provides an installation structure that achieves indirect carbon emission metering of electricity by practically improving existing computing and display resources. A simple and reliable carbon metering algorithm is designed.

The rarely used display characters "tiered remaining", "price", and "yuan" of the meter are modified to display the carbon measurement data characters "carbon emission", "factor", and "kg". Finally, the meter displays the carbon emission data of the power system through programming. The internal pressing protrusion 32 helps to press the outer locking buckle 12 and the inner locking buckle 13, allowing the protective cover 1 to be better installed and connected.

[0031] Example 2

[0032] Reference Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an installation structure that solves the problem of exposed wiring at the meter. It includes a protective cover 1, with an outer locking buckle 12 on the inner surface of the protective cover 1. A positioning block 14 is provided inside the protective cover 1, and an inner locking buckle 13 is provided on the outer surface of the positioning block 14. The structure of the inner locking buckle 13 is the same as that of the outer locking buckle 12. The protective cover 1 has a U-shaped structure. A gripping groove 11 is provided at one end of the protective cover 1 near the bottom of the groove, and an arc-shaped end 121 is provided at the end of the outer locking buckle 12 away from the gripping groove 11. The locking buckle 12 has a protruding end 122 at the end away from the arc end 121. A locking groove 33 is provided in the positioning groove 31.

After installation, the stability of the protective cover 1 after installation is improved, and the protection of the wiring terminal by the protective cover 1 is improved.

[0033] Example 3

[0034] Reference Figures 1 to 5 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a smart meter that solves the problem of not being able to display carbon metering data. It includes a protective cover 1, with an outer locking buckle 12 on the inner surface of the protective cover 1, a positioning block 14 inside the protective cover 1, and an inner locking buckle 13 on the outer surface of the positioning block 14. The structure of the inner locking buckle 13 is the same as that of the outer locking buckle 12. A meter box 2 is detachably connected to the protective cover 1. The meter box 2 is provided with a mounting connector 3, and a wiring hole 4 is reserved in the mounting connector 3. The smart meter receives carbon data information input from the outside. The carbon data information is input to the CPU management unit through the carbon emission measurement unit. In the CPU management unit, the carbon emission flow trajectory analysis model is used to calculate and freeze the data. The frozen data is input to the display unit. The display module displays the carbon emission data through programming. Users can view the carbon emission data on the LCD screen through the smart meter's rotary display button.

[0035] In use, the traditional LCD display of a smart meter is replaced with the display shown in this invention. The smart meter receives externally input carbon data information, which is then input into the CPU management unit through the carbon emission measurement unit. In the CPU management unit, the relevant data is calculated and frozen through the carbon emission flow trajectory analysis model. Smart meters are categorized into three types based on their installation location: generation-side carbon meters, grid-side carbon meters, and consumption-side carbon meters. The calculation methods for these different types of carbon meters are as follows: Generation-side inputs: Generator carbon emission factor, generator upstream gate electricity volume; Outputs: Generation-side carbon emission factor, generation-side carbon emissions. Generation-side carbon emission factor = Generator carbon emission factor; Generation-side carbon emissions = Generator carbon emission factor × Generator upstream gate electricity volume. Grid-side inputs: Total number of grid-side inflow branches, branch electricity volume at inflow nodes, branch carbon emission factor at inflow nodes, total number of grid-side outflow branches, branch electricity volume at outflow nodes; Outputs: Grid-side carbon emission factor, grid-side carbon emissions. Calculation method: Grid-side carbon emission factor = ∑(branch electricity volume at inflow nodes × branch carbon emission factor at inflow nodes) / ∑(branch electricity volume at outflow nodes). (Electricity), Grid-side carbon emissions = Grid-side carbon emission factor × ∑(Branch electricity flowing into the node - Branch electricity flowing out of the node), Electricity-side inputs: Electricity supplied to the node by distributed power source, carbon emission factor of distributed power source, branch carbon emission factor, electricity consumption at the metering point, Outputs: Electricity-side carbon emission factor, Electricity-side carbon emissions, Calculation method: Electricity-side carbon emission factor = Electricity supplied to the node by distributed power source × Carbon emission factor of distributed power source + Branch carbon emission factor × Electricity consumption at the metering point / Electricity supplied to the node by distributed power source + Electricity consumption at the metering point, Electricity-side carbon emissions = Electricity-side carbon emission factor × Electricity consumption at the metering point, The frozen data is input into the display module, and the carbon emission data is displayed in the display module through programming. Users can view the carbon emission data on the LCD screen through the smart meter's rotating display button.
