1 Product Overview

SC-GP-IR4G wireless infrared meter reading terminal is a general electrical meter and gas meter reading terminal based on infrared communication, 4G wireless transmission, DC wide voltage power supply, launched by Shanghai Data Acquisition IOT Technology Co., LTD., which can collect electric energy data, voltage, current, power factor and other electrical parameter data of State grid meters.

Introduction to the principle of infrared meter reading: infrared photoelectric probe through the infrared port to read the parameter information of smart meters and upload. The infrared meter reader has the function of infrared signal modulation and demodulation, modulates the binary digital signal into 38KHz frequency pulse sequence, and drives the infrared emitting diode to send out in the form of infrared light pulse. The transceiver converts the received optical pulse into an electrical signal, and then sends it to the demodulation circuit for demodulation after amplification and filtering. After the message is parsed, it is sent to the server in a specified format (such as Json).

Wireless infrared meter reading terminal supports 4G/NB-IOT/LoRa communication mode, which greatly simplifies field deployment time and reduces construction costs. This product supports various meter reading scenarios with infrared communication interface, such as electric meters, gas meters, flow meters and other meters. This product is suitable for energy meter data collection, 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, cloud platform system data collection and energy meter verification test bench. This product is especially suitable for the power supply bureau of the state grid meter master meter seal is completely closed, and cannot be open any seal of the situation of meter reading.
