DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] In order to further describe the structural features, technical means, and specific objectives and functions that can be achieved by the present invention, the present invention will be described in detail below with reference to specific examples in conjunction with the drawings. (One embodiment)

[0023] The following is the schematic diagram and specific implementation of this invention.

[0024] As shown in Figures 1 to 3, the solar communication gateway is used to connect the power grid and the distribution board in series, and includes 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 used to connect to an electric vehicle and with a built-in third power relay, and a communication hub 14 for wirelessly connecting to a cloud server 21 or a mobile terminal 22.

[0025] 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 by wires, respectively.

[0026] In this embodiment, the communication hub 14 includes an MCU, an external communication interface module respectively connected to the MCU, and a power management module for use in supplying electricity. The MCU is connected to a memory, the first smart meter 11, the second smart meter 12 and the third smart meter 13 by wires, respectively.

[0027] The external communication interface module includes at least two communication modules, one of which is a remote communication module (e.g., 4G, 5G, 5GA, etc.) that is mainly used for communication with the cloud server 21. The other is a short-range wireless communication module (e.g., Wi-Fi®, Wi-SUN®, Bluetooth®, etc.) that communicates with various energy sources, home appliance devices (e.g., utility smart meters, batteries, carbon dioxide heat pump fuel dispensers, etc.) or mobile terminals.

[0028] In addition to the wireless communication channel, the external communication interface module can further connect with wired LAN, RS485 and PLC, for example, directly dealing with different energy source devices such as photovoltaic inverters, charging / discharging devices of electric power vehicles, network routers and electric power vehicles.

[0029] The first smart meter and the second smart meter 12 are connected together in series between the power grid and a switchboard, which is used to power household devices.

[0030] The first smart meter is used to connect to the power grid. In this embodiment, the cloud server 21 can remotely disconnect the connection between the first smart meter 11 and the power grid to reduce current fluctuations or solve safety issues during maintenance. In addition, when the solar communication gateway of this embodiment detects that energy is flowing from the first smart meter 11 to the power grid, the solar communication gateway of this embodiment will automatically disconnect from the power grid. This prevents the energy source (e.g., a solar power generation system or a power-driven vehicle) from outputting to the power grid, and ensures that all green energy sources are only used by household appliances and their corresponding apps.

[0031] The second smart meter 12 is used to connect to the distribution board, the solar power inverter, the battery and the carbon dioxide heat pump fuel dispenser.

[0032] The second smart meter 12 can measure the amount of solar power generation at any time and report it to the cloud server 21 via the communication hub 14. This allows the cloud server 21 to remotely adjust the power of the solar power inverter and manage the battery and the CO2 heat pump fuel machine. The energy generated by the solar panel during the day is stored in the battery and / or the CO2 heat pump fuel machine and then released at night to power household appliances, thus maximizing the efficiency of solar energy and reducing the need for the power grid.

[0033] At least one of the first smart meter, the second smart meter and the third smart meter is a guide rail type smart meter. In this embodiment, the first smart meter 11, the second smart meter 12 and the third smart meter are all guide rail type smart meters.

[0034] The third smart meter 13 is connected to a communication hub 14 .

[0035] The third smart meter 13 is used to measure the energy flow between the charger / discharger of the electric vehicle and the system. It can switch the power connection of the electric vehicle device using the internal third power relay. As more and more electric vehicles can charge or output energy to the grid like a large battery, the third smart meter 13 can measure the electric energy and remotely control the electric vehicle energy source for household appliances or emergency use. Wired cables (e.g. LAN, PLC, RS485, etc.) connect the solar communication gateway of this embodiment to the electric vehicle device or the electric vehicle. They allow the cloud server 21 to directly communicate with the electric vehicle or V2H device, manage the electric vehicle and solar power generation operation, and manage data collection via the new communication center.

[0036] The communication hub 14 is connected to the artificial intelligence AI chip. When analyzing the energy source data through the artificial intelligence AI chip, machine learning is performed. The MCU reserves a dedicated program area in advance, and continuously updates the AI ​​learning model from the cloud server 21 via MCU OTA.

[0037] The communication system includes a cloud server 21, a mobile terminal 22, a solar power generation inverter, a power grid, a switchboard, a gateway, an electric vehicle, a battery and a carbon dioxide heat pump fuel dispenser, and the gateway is a solar power communication gateway.

[0038] The first smart meter is connected to the interconnected power grid. The second smart meter 12 is connected to a switchboard, a photovoltaic inverter, a battery and a carbon dioxide heat pump fuel dispenser.

[0039] The cloud server 21 or communication hub is wired to the electrically powered vehicles for directly managing the charging or discharging of the electrically powered vehicles.

[0040] The power supply switching method is applied to a communication system.

[0041] Electrically powered vehicles, also known as EVs, refer to vehicles that are propelled by an electric motor and have a local device to provide stored power to the motor, which can also be used to provide electricity to a home.

[0042] The power supply switching method includes the following steps.

[0043] In step 1, first, the photovoltaic inverter, the battery, or the electric vehicle is controlled through the communication hub, and simultaneously performs the preset operations, that is, the first power relay of the first smart meter is disconnected, the second power relay of the second smart meter is disconnected, and the third power relay of the third smart meter is disconnected.

[0044] Next, detect and determine whether the solar communication gateway and the cloud server are connected to each other. If yes, proceed to step 2; if no, proceed to step 11.

[0045] In step 2, the solar communication gateway itself directly reports the energy source data after integration and analysis in the first smart meter, the second smart meter and the third smart meter to the cloud server, and then proceeds to step 3.

[0046] In step 3, the grid powers the switchboard and simultaneously charges the battery or electric vehicle through the communications hub, before proceeding to step 4.

[0047] In step 4, it is determined whether the photovoltaic energy is greater than the energy consumption of the house. If yes, proceed to step 5; if no, keep the first power relay of the first smart meter in the off state through the communication hub to continue supplying electricity to the power grid.

[0048] In step 5, first, open the first power relay of the first smart meter through the communication hub to disconnect it from the power grid. Then, charge the battery or the carbon dioxide heat pump fuel dispenser using the solar power generation energy through the communication hub. When the battery or the carbon dioxide heat pump fuel dispenser is full, determine whether the solar power generation energy is less than the energy consumption of the house. If yes, proceed to step 2; if no, proceed to step 6.

[0049] In step 6, the third power relay of the third smart meter is kept in an OFF state via the communication hub, so that the electric vehicle can be charged with energy from the solar energy.

[0050] In step 7, if the electric vehicle is already full or the photovoltaic power generation energy is less than the energy consumption of the house, stop charging the electric vehicle; if not, charge the electric vehicle until it is full.

[0051] In step 8, it is determined whether the photovoltaic energy is greater than the energy consumption of the house. If yes, proceed to step 9; if no, return to step 3.

[0052] In step 9, select whether to output the photovoltaic energy to the power grid or to continue to use it only for consumption in the house. If it is selected to output the photovoltaic energy to the power grid, the first power relay of the first smart meter is controlled to be cut off via the communication hub, and then the photovoltaic energy is output through the power grid to realize electricity sales. Or, if it is selected to continue to use it only for consumption in the house, first, the third power relay of the third smart meter is controlled to be opened via the communication hub, and then the photovoltaic inverter output power is adjusted via the communication hub to match the distribution board to each home device in the house, and electricity is supplied until the photovoltaic energy is insufficient to supply electricity to each home device in the house. Then, proceed to step 10.

[0053] In step 10, the communication hub controls the battery or controls the third power relay of the third smart meter to cut off, so as to realize that the power-driven vehicle supplies electricity to each individual home device in the house until the battery or the power-driven vehicle is insufficient to supply electricity to the home devices. Then, proceed to step 1.

[0054] In step 11, first wirelessly connect the solar communication gateway to the mobile terminal through the short-range wireless communication module, then wirelessly connect the mobile terminal to the cloud server, and then realize the wireless connection between the solar communication gateway and the cloud server. The solar communication gateway reports the integrated and analyzed energy source data from the first smart meter, the second smart meter and the third smart meter to the cloud server through the mobile terminal. Then, return to step 3.

[0055] As mentioned above, it mainly forms a solar communication gateway through the first smart meter, the second smart meter and the communication hub, and users can use different green energy equipment to adjust the power generation, energy storage or consumption mode to achieve zero carbon emissions. In particular, the electricity supply mode can be switched between supplying electricity from surplus solar power generation or selling it. Furthermore, electricity can be supplied via electric vehicles or batteries to make full use of surplus solar energy, greatly improving the flexibility of the electricity supply mode.

[0056] Next, by installing the third smart meter, electric vehicles can be managed collectively, which increases the efficiency of the overall use of energy sources and allows electric vehicles to be used as emergency power sources. The communication hub, first smart meter, second smart meter and third smart meter are all installed on the same housing, which allows for a high level of integration and makes subsequent installation even easier.

[0057] The above is merely a preferred embodiment of the present invention, and does not limit the scope of the claims of the present invention. Therefore, any minor modifications and equivalent changes and modifications of the above embodiments based on the technical essence of the present invention shall all belong to the scope of the claims of the present invention.
