The DAQ-GP-IRMODBUSRTU infrared meter reading terminal, developed by Shanghai Data Acquisition IoT Technology Co., Ltd., is a device that converts State Grid electric meters such as DLT645/698 into the ModBus communication protocol. It can collect electrical energy data, voltage, current, power factor, and other electrical parameters from State Grid meters.
Overview of Infrared Meter Reading Principle: The infrared photoelectric probe periodically reads parameter information from the smart meter via the infrared optical port and uploads the data. The infrared meter reader features infrared signal modulation and demodulation functions, modulating binary digital signals into a 38 kHz frequency pulse sequence and driving the infrared emitting diode to transmit these as infrared light pulses. The transceiver converts received optical pulses into electrical signals, which are then amplified and filtered before being sent to the demodulation circuit for demodulation. The signals are restored to binary digital form, parsed into data packets, and converted into the ModBus protocol, enabling reading by other host computer software.
This terminal supports meter reading scenarios for various instruments equipped with infrared communication interfaces, such as electric meters and gas meters. It is suitable for electric energy meter data acquisition, smart city data acquisition, power monitoring data acquisition, energy-saving and emission reduction data monitoring system acquisition, energy consumption monitoring system data acquisition, photovoltaic system data acquisition, intelligent monitoring data acquisition, robot data acquisition, smart security system data acquisition, and cloud platform system data acquisition. Electric Energy Meter Verification and Testing Platform; particularly suitable for photovoltaic power generation system meter reading and State Grid electric meter main meter reading under fully sealed lead seal conditions, where no seals may be opened.
