Technical Field

[0001] This utility model relates to the field of electricity metering technology, and in particular to a smart electricity meter with four-channel metering control. Background Technology

[0002] A smart meter is an electricity metering device based on digital and Internet of Things (IoT) technologies. Compared to traditional meters, it offers intelligent functions such as real-time monitoring, remote meter reading, and data analysis. Technically, smart meters use built-in sensors to monitor parameters such as voltage and current in real time, transmitting the collected data to the cloud for processing. This allows users to check their real-time electricity consumption anytime, anywhere via a mobile app or computer. Power companies can also leverage big data analytics to deeply analyze electricity data, providing more accurate data for grid operation.

[0003] However, existing smart meters have the following drawbacks:

[0004] 1. The metering accuracy of existing smart meters may be limited, which may lead to inaccurate measurement of electricity consumption, thereby affecting electricity billing and energy management.

[0005] 2. When carrying high current, the heat dissipation performance may be insufficient, which may cause the equipment to overheat during long-term operation, affecting stability and lifespan.

[0006] 3. The control function is weak, and it is impossible to achieve remote or automatic control of each branch circuit, which limits the user's intelligent management of home appliances.

[0007] 4. The structural design is not sophisticated, and the volume is often large.

[0008] In summary, existing smart meters may have shortcomings in areas such as metering accuracy, heat dissipation, control functions, communication capabilities, anti-theft capabilities, prepaid functionality, and adaptability. These deficiencies may affect users' electricity experience and the management efficiency of power supply companies. Summary of the Invention

[0009] The technical problem to be solved by this utility model is to provide a smart energy meter with four-way metering control, which has the characteristics of compact structure, high current sampling accuracy, control function and good current carrying capacity.

[0010] The technical solution adopted by this utility model to solve its technical problem is as follows: a smart energy meter with four-way metering control, including a housing, in which a relay module, a power supply module, and a display module are disposed; the relay module includes a relay PCB circuit board, on which four relays are integrated, and the four relays are arranged to form a cavity within the housing; the power supply module includes a power supply PCB circuit board, on which a power supply component is disposed, and when the power supply module and the relay module are installed and connected, the power supply PCB circuit board is flipped up above the relay module, and the power supply component is located within the cavity formed by the arrangement of the four relays; the display module is disposed above the power supply module; the relay module has one input terminal and four output terminals.

[0011] Furthermore, the input and output terminals of the relay module described in this utility model are both copper plates, which are directly soldered onto the relay PCB circuit board.

[0012] Furthermore, the relay PCB circuit board of this utility model is provided with a surface-mount manganese copper plate, which samples the current.

[0013] Furthermore, the power supply component of this utility model is disposed on the front side of the power supply PCB circuit board, and a power strip interface is disposed on the back side of the power supply PCB circuit board. The display module is provided with matching pins, and the display module is connected to the power supply module by inserting the pins into the power strip interface.

[0014] Furthermore, the relay PCB circuit board of this utility model has copper foil, and the load current is conducted through the copper foil.

[0015] The beneficial effect of this utility model is that it solves the defects existing in the background technology.

[0016] The relay module and power supply module are placed in a reverse-interlocking manner, which can greatly reduce the size of the electricity meter and does not affect the operation of each part.

[0017] It adopts a one-input, four-output design structure, that is, one input terminal is connected to the power supply, and four output terminals are connected to different loads or circuit branches respectively; this design enables the smart energy meter to monitor and control the working status and energy consumption of up to four independent circuits at the same time.

[0018] In terms of hardware configuration, this invention employs copper components soldered onto a PCB board, improving overall stability and reliability. Simultaneously, by utilizing surface-mount manganese copper current sampling technology, the current sampling element is directly mounted on the PCB board, enabling accurate measurement of the load current. Furthermore, the PCB board integrates four relays, giving the smart meter the ability to remotely or automatically control each branch circuit.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] like Figures 1-2 The smart energy meter shown includes a housing 1, within which a relay module 2, a power module 3, and a display module 4 are housed. The relay module 2 includes a relay PCB circuit board 5, on which four relays 6 are integrated. These four relays, arranged in a configuration, form a cavity 7 within the housing. The power module 3 includes a power PCB circuit board 8, on which a power assembly 9 is mounted. When the power module 3 is connected to the relay module 2, the power PCB circuit board 5 is mounted upside down on top of the relay module 2, and the power assembly 9 is located within the cavity 7 formed by the four relays. This placement of the power assembly within the cavity significantly reduces the overall height of the energy meter, making the height of the two modules stacked almost the same as the height of a single module, thus saving installation space.

[0025] Relay module 2 has one input terminal and four output terminals. It adopts a one-input, four-output design structure, that is, one input terminal is connected to the power supply, and the four output terminals are connected to different loads or circuit branches respectively; this design allows the smart energy meter to simultaneously monitor and control the operating status and energy consumption of up to four independent circuits.

[0026] The display module 4 is positioned above the power module 3; the power supply assembly 9 is located on the front of the power PCB circuit board 8, and a connector is located on the back of the power PCB circuit board 8. The display module 4 has matching pins, and the display module connects to the power module by inserting the pins into the connector. The display module adopts a pluggable connection structure, which facilitates replacement and maintenance in case of failure.

[0027] In terms of hardware configuration, the input and output terminals of relay module 2 are both copper plates 10, which are directly soldered onto the relay PCB circuit board 5. Using copper components soldered onto the PCB board improves overall stability and reliability. Simultaneously, through surface-mount manganese copper current sampling technology, the current sampling element is directly mounted on the PCB board, thereby achieving accurate measurement of the load current. Furthermore, four relays are integrated on the PCB board, enabling the smart meter to remotely or automatically control each branch circuit.

[0028] The relay PCB circuit board 5 has surface-mount manganese bronze plates that sample the current. The relay PCB circuit board also has copper foil, through which the load current is conducted. This solves the problem of high current carrying capacity by utilizing the PCB board copper foil as the conduction path for the load current. By optimizing the copper foil layout and increasing the copper foil area, heat dissipation performance is effectively improved, enabling the double-sided copper foil design to carry a maximum total current of 60A, with a maximum of 20A per branch. This innovative design not only ensures the safety of the equipment but also expands its application range.
