Electric Meter Data Acquisition Terminal and Meter Reading Device: Supports Multiple Protocols Conversion to MQTT and Other Protocols

SC-GP-IR 4 G wireless infrared meter reading terminal is a general electricity meter gas meter reading terminal based on infrared communication, GPRS wireless transmission, DC wide voltage power supply launched by Shanghai Digital Mining Internet of Things Technology Co., LTD. It can collect power data, voltage, current, power factor and other power parameters of state grid electricity meter (support 645 and 698 protocol).

Introduction to the principle of infrared meter reading: The infrared photoelectric probe can regularly read the parameter information of the smart meter through the infrared optical port and upload it. The infrared meter reader has the function of infrared signal modulation and demodulation, modulates the binary digital signal into a pulse sequence of 38 KHz frequency, and drives the infrared emitting diode to send in the form of infrared light pulse; the transceiver transforms the received light pulse into electrical signal, and then amplify, filter and send to the demodulation circuit for demodulation, restore to the binary digital signal, after the message analysis, send to the server according to the specified format (such as json).

The wireless infrared meter reading terminal supports the GPRS / 2G / 4G / NB-IOT / LoRa communication mode, which greatly simplifies the site deployment time and reduces the construction cost. The terminal supports all scenarios of meters, suitable for electricity meter data collection, smart city data collection, power monitoring data collection, energy saving 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 data collection; electricity meter verification and testing table; especially suitable for the photovoltaic power generation system and the total meter of the power grid Bureau are completely closed, and cannot open any seal.
