[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0032] like Figures 1 to 3 As shown, a solar communication gateway is used to be connected in series between the power grid and the distribution box, including a housing, a memory, a first smart meter 11 with a built-in first power relay, a second smart meter 12 with a built-in second power relay, a third smart meter 13 with a built-in third power relay for connecting to an electric vehicle, and a communication hub 14 for wirelessly connecting to a cloud server 21 or a mobile terminal 22;

[0033] The communication hub 14, the first smart meter 11, the second smart meter 12 and the third smart meter 13 are all mounted on a housing 15. The communication hub 14 is connected to the memory, the first smart meter 11, the second smart meter 12 and the third smart meter 13 via wires.

[0034] In this embodiment, the communication hub 14 includes an MCU, an external communication interface module connected to the MCU, and a power management module for power supply. The MCU is connected to the memory, the first smart meter 11, the second smart meter 12, and the third smart meter 13 through wires.

[0035] The external communication interface module includes at least two communication modules, one of which is a long-range communication module (such as 4G, 5G, 5GA, etc.), which is mainly used to communicate with the cloud server 21; the other is a short-range communication module (such as Wi-Fi, Wi-Sun, Bluetooth, etc.) to communicate with various energy sources, household appliances (such as utility smart meters, batteries, carbon dioxide heat pump water heaters, etc.) or mobile terminals.

[0036] In addition to wireless communication channels, the external communication interface module can also connect to wired LAN, RS485 and PLC to directly handle different energy devices such as solar inverters, charging / discharging equipment for electric drive vehicles, network routers and electric drive vehicles.

[0037] The first smart meter and the second smart meter 12 are connected in series between the power grid and a distribution box for supplying power to household appliances.

[0038] The first smart meter is connected to the power grid; in this embodiment, the cloud server 21 can remotely disconnect the first smart meter 11 from the grid to reduce current fluctuations or address safety issues during maintenance. Furthermore, if the solar communication gateway of this embodiment detects energy flowing from the first smart meter 11 to the grid, it can automatically disconnect from the grid. This prevents energy (e.g., solar power generation or electric vehicles) from being exported to the grid, ensuring that all green energy is used exclusively for home appliances and corresponding applications.

[0039] The second smart meter 12 is used to connect to the distribution box, the solar inverter, the battery and the carbon dioxide heat pump water heater.

[0040] The second smart meter 12 measures solar power generation in real time and reports this to the cloud server 21 via the communication hub 14. This allows the cloud server 21 to remotely adjust the power of the solar inverter and manage the battery and CO2 heat pump water heater. The energy generated by the solar panels during the day can be stored in the battery and / or CO2 heat pump water heater and then released at night to power household appliances, maximizing the efficiency of solar-generated energy and reducing demand on the grid.

[0041] At least one of the first smart meter, the second smart meter, and the third smart meter is a rail-type smart meter. In this embodiment, the first smart meter 11, the second smart meter 12, and the third smart meter are all rail-type smart meters.

[0042] The third smart meter 13 is connected to the communication hub 14 .

[0043] The third smart meter 13 is used to measure the energy flow between the electric vehicle's charger / discharger and the system. It can use its internal third power relay to switch the power connection of the electric vehicle equipment. As more and more electric vehicles can charge or output energy to the grid like giant batteries, the third smart meter 13 can measure electrical energy and remotely control the electric vehicle energy for household appliances or emergency applications. A wired cable (such as LAN, PLC, RS485, etc.) connects the solar communication gateway of this embodiment to the electric vehicle equipment or electric vehicle. Therefore, the cloud server 21 can communicate directly with the electric vehicle or V2H device, manage the electric vehicle and solar power generation operations, and collect data through the new communication center.

[0044] The communication hub 14 is connected to an artificial intelligence (AI) learning chip. This AI learning chip enables machine learning when analyzing energy data. The MCU reserves a dedicated program area, allowing for continuous updates of the AI learning model from the cloud server 21 via MCU OTA.

[0045] A communication system includes a cloud server 21, a mobile terminal 22, a solar inverter, a power grid, a distribution box, a gateway, an electric vehicle, a battery and a carbon dioxide heat pump water heater, wherein the gateway is the solar communication gateway.

[0046] The first smart meter is connected to the power grid. The second smart meter 12 is connected to the distribution box, the solar inverter, the battery and the carbon dioxide heat pump water heater.

[0047] The cloud server 21 or the communication hub is connected to the electric vehicle via a wired connection to directly manage the charging or discharging of the electric vehicle.

[0048] A power supply mode switching method is applied to a communication system.

[0049] An electric vehicle, also known as an EV, refers to a vehicle that is propelled by an electric motor and has a local means for storing electricity to power the electric motor, which can be used to power a house.

[0050] The power supply mode switching method comprises the following steps:

[0051] Step 1: First, the solar inverter, the storage battery, or the electric drive vehicle is controlled by the communication hub to simultaneously perform a preset operation, that is, the first power relay of the first smart meter is closed, the second power relay of the second smart meter is closed, and the third power relay of the third smart meter is closed;

[0052] Next, determine whether the solar communication gateway and the cloud server are connected. If yes, go to step 2; if not, go to step 10.

[0053] In step 2, the solar communication gateway itself can directly report the integrated and analyzed energy data from the first smart meter, the second smart meter, and the third smart meter to the cloud server, and then execute step 3;

[0054] Step 3: The power distribution box is powered by the power supply of the grid, and at the same time, the battery or electric drive vehicle is charged through the communication hub, and then step 4 is executed;

[0055] Step 4: Determine whether the solar power generation energy is much greater than the energy consumption of the house. If so, execute step 5. If not, control the first power relay of the first smart meter through the communication hub to remain in a closed state, and continue to be powered by the power supply of the grid;

[0056] Step 5: First, the communication hub is used to control the first power relay of the first smart meter to open, thereby disconnecting the power supply from the grid. Then, the communication hub is used to charge the battery or the CO2 heat pump water heater using the solar power generation energy. When the battery or the CO2 heat pump water heater reaches full capacity, it is determined whether the solar power generation energy is less than the energy consumption of the house. If so, step 2 is executed; otherwise, step 6 is executed.

[0057] Step 6: Control the third power relay of the third smart meter to remain in a closed state through the communication hub, so that the solar energy is used to charge the electric vehicle;

[0058] Step 7: If the electric vehicle has reached full capacity or the solar power generation energy is less than the energy consumption of the house, then stop charging the electric vehicle; otherwise, continue charging until the electric vehicle reaches full capacity;

[0059] Step 8: Determine whether the solar power generation energy is still greater than the energy consumption of the house. If so, execute step 9; if not, jump to step 3;

[0060] Step 9: Select whether to export the solar-generated energy to the grid or continue to use it only for energy consumption in the house. If the solar-generated energy is exported to the grid, the communication hub controls the first power relay of the first smart meter to close, and then the solar-generated energy is exported to the grid to sell electricity. If the solar-generated energy is continued to be used only for energy consumption in the house, the communication hub controls the third power relay of the third smart meter to open, and then the communication hub adjusts the output power of the solar inverter to cooperate with the distribution box to power various household devices in the house until the solar-generated energy is insufficient to power various household devices in the house, and then executes step 10.

[0061] Step 10: The communication hub controls the battery or controls the third power relay of the third smart meter to be closed, so that the electric vehicle can supply power to various household devices in the house until the battery or the electric vehicle is insufficient to supply power to the household devices. Then, step 1 is executed.

[0062] In step 11, the solar communication gateway is first wirelessly connected to the mobile terminal through the short-range communication module, and then the mobile terminal is wirelessly connected to the cloud server. Then, the solar communication gateway is wirelessly connected to the cloud server. The solar communication gateway reports the integrated and analyzed energy data from the first smart meter, the second smart meter, and the third smart meter to the cloud server through the mobile terminal, and jumps to step 3.

[0063] In summary, it mainly forms a solar communication gateway through the first smart meter, the second smart meter and the communication hub, which makes it convenient for users to use different green energy devices and adjust the power generation, storage or consumption methods to achieve zero carbon emissions. In particular, the power supply method can be switched to first supply power or sell electricity through excess solar power generation, and then supply power through electric-powered vehicles or batteries, which is conducive to making full use of excess solar energy and greatly improving the flexibility of power supply methods.

[0064] Secondly, by setting up a third smart meter, electric vehicles can be managed together, the overall energy utilization efficiency can be increased, and electric vehicles can be used to provide emergency power. Through the communication hub, the first smart meter, the second smart meter and the third smart meter are all installed on the shell, with a high degree of integration, which is convenient for subsequent laying.

[0065] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
