The DAQ-GP-IRMODBUSRTU infrared meter reading terminal is a device launched by Shanghai Shucai Internet of Things Technology Co., Ltd. that can convert national grid electricity meters such as DLT645/698 into ModBus communication protocol. It can collect electricity data, voltage, current, power factor and other electrical parameter data from national grid electricity meters.

Introduction to the principle of infrared meter reading: The infrared photoelectric probe regularly reads the parameter information of the smart meter through the infrared light port and uploads it. The infrared meter reader has the function of infrared signal modulation and demodulation, which modulates binary digital signals into a pulse sequence of 38KHz frequency and drives the infrared emitting diode to send out in the form of infrared light pulses; The transceiver converts the received optical pulse into an electrical signal, which is then amplified, filtered, and processed before being sent to the demodulation circuit for demodulation. It is restored to a binary digital signal, which is then parsed into a ModBus protocol and can be read by other upper computer software.

This terminal supports various meter reading scenarios for electricity meters, gas meters, and other instruments with infrared communication interfaces. It is suitable for data collection of electricity meters, smart city data collection, power monitoring data collection, energy conservation and emission reduction data monitoring system data collection, energy consumption monitoring system data collection, photovoltaic system data collection, intelligent monitoring data collection, robot data collection, intelligent security system data collection, and cloud platform system data collection; Electric energy meter calibration and inspection test bench; Especially suitable for photovoltaic power generation system energy meter reading and meter reading in the state where the lead seal of the power supply bureau's national grid electricity meter is completely closed, and no seal can be opened.
