The implementation steps of the electric energy meter comprise:
integration of LI-FI communication modules
First, in the design phase of the electric energy meter, the LI-FI communication module needs to be integrated into the hardware structure of the electric energy meter. The LI-FI communication module comprises a light emitting device and a light receiving device, wherein the light emitting device uses an LED (light emitting diode) or other visible light emitters for converting data into visible light signals for transmission; the light receiving device includes a photoelectric converter (PD) for receiving an externally transmitted visible light signal and converting it into an electrical signal for decoding.
The data processing in the LI-FI communication module refers to processing in the LI-FI communication module, and comprises tasks such as data coding, modulation (converting a digital signal into a visible light signal), demodulation (converting a received visible light signal into a digital signal), data analysis (converting the data into readable data according to a communication protocol) and the like. The LI-FI communication module has the main task of processing operations related to optical communication and transmitting data through visible light.
2. Data transmission flow design
The LI-FI communication data transmission flow is designed to comprise the processes of data coding, modulation, demodulation and the like. When the electric energy meter is used as a transmitting end, data to be transmitted are subjected to coding processing, then digital signals are modulated into optical signals through a modulator, and the optical signals are transmitted through an LED. When the electric energy meter is used as a receiving end, the light receiving device (photoelectric converter) receives the visible light signal and converts the visible light signal into an electric signal, and corresponding analog information is finally demodulated through filtering, shaping and amplifying processing.
The data coding mainly comprises data input, data processing and digital signal coding. The data input is specifically that raw data enters an electric energy meter system from various channels such as sensors or user input of the electric energy meter; such data may include power usage data, cost information, and the like. Data processing, in particular, may require processing, including checking, error correcting code, etc., before the data is transmitted to ensure accuracy and integrity of the data. The digital signal encoding is in particular the conversion of the processed digital data into a specific encoded form by the encoding module, which may comprise a modulation, encoding scheme, e.g. the encoding of the digital signal into modulated binary data.
Data modulation involves a modulator and an LED light emitting diode. A modulator inside the electric energy meter converts the digital signal into an optical signal; this process typically involves combining a digital signal with a specific modulated waveform to produce an optical signal over the visible spectrum. This can be achieved by varying the current or brightness of the LED light emitting diode, thereby varying the intensity and frequency of the light signal. As part of the light emitting device, the LED light emitting diode converts the modulated digital signal into an optical signal; the brightness and frequency of the LEDs vary with the digital signal to transmit data in the visible spectrum.
Data demodulation involves an optoelectronic converter (PD) and demodulator, including filtering, shaping, amplifying, and data processing. When the electric energy meter is used as a receiving end, a photoelectric converter (PD) in the light receiving equipment receives visible light signals transmitted from outside; the PD is responsible for converting visible light signals into electrical signals. The received electrical signal is filtered, shaped and amplified to remove noise and recover the shape and strength of the original signal. The demodulator decodes the processed electrical signal into a digital signal; this process involves converting the intensity and frequency of the optical signal back to a specific form of digital signal. The decoded digital signal is further processed, including parsing, checksum storage, to ensure accuracy and integrity of the data. The modules in the processes cooperate to ensure that data is transmitted from the transmitting end to the receiving end of the electric energy meter and finally decoded into original data. Importantly, these steps require precise time synchronization and parameter coordination to ensure reliable transmission and accuracy of the data.
3. Communication interface and control chip design
And designing a communication interface and a control chip of the electric energy meter, and processing the transmitted and received data and analyzing and controlling an LI-FI communication protocol. The communication interface and the control chip in the electric energy meter are responsible for sending data from other modules of the electric energy meter to the LI-FI communication module or receiving data from the LI-FI communication module. The communication interface and control chip may need to handle some of the data format conversion, data frame encapsulation, etc. tasks to ensure that data can be efficiently transmitted to and received from the LI-FI communication module.
The communication interface is responsible for transmitting the processed data to the LI-FI communication module, and the control chip is responsible for controlling parameters such as time sequence and frequency of communication, so that accuracy and stability of data transmission are ensured. Typically, the specific values of timing and frequency will be determined based on the design requirements of the power meter, the standard of the LI-FI communication protocol, and the performance of the associated hardware. These values typically require detailed engineering planning and testing during the design and development stages of the power meter to ensure accuracy and stability of the communication. Timing generally relates to parameters in terms of clock rate of data transmission, data sampling rate, timing requirements of data frames, and the like. The frequency refers to a carrier frequency at the time of modulation and demodulation of data, a frequency bandwidth of a communication channel, and the like. The specific timing and frequency parameters will vary with different power meter models, LI-FI communication standards, hardware configurations, and performance requirements. Therefore, these parameters are typically defined and optimized in detail in the specific engineering of the design of the electric energy meter to meet specific communication requirements.
4. Security module integration
In order to ensure the communication safety, a safety module is integrated in the electric energy meter for data encryption and identity authentication. The security module is responsible for encrypting and protecting the transmitted data, ensuring the confidentiality and the integrity of the data in the communication process, and simultaneously, can also perform identity authentication to prevent illegal operation and replay attack.
5. Display unit and metering unit design
The display unit and the metering unit of the electric energy meter are designed, and the display unit is responsible for displaying electric energy use data, cost information and the like in real time; the metering unit is responsible for measuring and metering the electric energy and ensuring accurate recording of the use of the electric energy.
6. Charge control unit integration
And the cost control unit is integrated, so that the electric energy meter can perform remote cost control opening and closing operation through LI-FI technology. The cost control unit is combined with the LI-FI communication module to realize a remote cost control function and help a user to manage and control the cost.
The remote fee-controlled opening and closing operation means that the electric energy meter has the function of controlling the power supply or the power failure of the electric energy in a remote communication mode. In general, this function is used for realizing remote electric charge management and electricity consumption control, and mainly includes the following aspects:
remote brake-off operation: the electric energy meter can receive a remote instruction from an electric power supply department or a user through LI-FI technology to disconnect a power supply, so that a tested circuit or an electric device stops supplying power. This is typically used in situations where the user is overdue, is not paying electricity, or needs to be temporarily powered down. Through remote brake-off, the power supply department can realize the power failure operation of the owed fee user, and the user can also manage the electric fee through the remote brake-off function, so as to ensure the effective management of the electricity utilization compliance and fee.
Remote closing operation: in contrast to remote switching off, remote switching on refers to the fact that the electric energy meter can receive remote instructions from the power supply department or a user through LI-FI technology to reconnect the power supply, so that the tested circuit or the electrical equipment can be powered back. This is typically used after a user pays a fee or in the event that a restoration of power supply is required. The user can conveniently and rapidly recover the electricity service after paying the arrearage through the remote closing function.
In a word, the remote fee-controlled opening and closing operation is a remote control function for realizing power supply through a remote communication technology, so that the supply of electric fee and electric energy can be effectively managed, and the intellectualization and convenience of the electric energy meter are improved.
7. Remote monitoring function design

The remote monitoring function is designed, so that efficient data interaction between the electric energy meter and the main station system is ensured, and a user can acquire electric energy use data and equipment state information in real time through the remote monitoring platform.
