Abstract: With the promotion and application of smart IoT electric energy meters (hereinafter referred to as “IoT meters”), their verification methods face new challenges. Traditional electric energy meter verification relies on photoelectric pulse acquisition and RS 485 communication interface, while IoT meters eliminate auxiliary terminals and adopt Bluetooth 5.0 and above versions for data interaction, making the existing verification assembly line difficult to directly compatible. To address this issue, a communication device that integrates radio frequency transmission and photoelectric conversion is designed. The device integrates a Bluetooth module group, a photoelectric acquisition unit, a main control unit, an isolated power supply, and a communication interface, supporting RS 485 communication and BLE5.0 protocol. It can not only transmit verification pulses through radio frequency signals and electrical pulse conversion via a 2.4G frequency band private protocol but also accurately capture LED light pulse signals through a photoelectric acquisition circuit. The two pulse transmissions are independent and can be output simultaneously. The device adopts a modular design, featuring multi- channel frequency hopping anti-interference, signal isolation protection, parameter storage, and display indication. It can be seamlessly integrated into existing verification platforms to achieve wireless and efficient verification of IoT meters. Practical applications show that the device is easy to install, stable in operation, and effectively improves verification efficiency and adaptability.
