What is the principle of remote meter reading in electric power bureau?

Brief introduction of wireless infrared meter reading principle of electric energy meter: infrared photoelectric probe reads the parameter information of intelligent electric meter regularly through infrared port and uploads it. The infrared meter reader has the function of infrared signal modulation and demodulation, which modulates the binary digital signal into 38KHz? Frequency pulse sequence, and drive the infrared light emitting diode to send out in the form of infrared pulse; The transceiver converts the received optical pulse into an electrical signal, which is sent to the demodulation circuit for demodulation after amplification, filtering and other processing, and returns to a binary digital signal, which is sent to the server according to a specified format (such as json) after message analysis.

The wireless infrared meter reading terminal SC-GP-IR2G/4G is a universal meter reading terminal based on infrared communication, GPRS, 4G/NB-IOT wireless transmission and DC wide voltage power supply, which can collect power data, voltage, current, power factor and other power parameter data of the national grid meter.

The wireless infrared meter reading terminal supports GPRS/2G/4G/NB-IOT/LoRa communication mode, which greatly simplifies the on-site deployment time and reduces the construction cost. The terminal supports meter reading scenarios of various meters with infrared communication interfaces such as electric meters and gas meters, and is suitable for data acquisition of electric meters, smart cities, power monitoring systems, energy consumption monitoring systems, photovoltaic systems, intelligent monitoring systems, robots, intelligent security systems and cloud platforms. Electric energy meter calibration test-bed; It is especially suitable for electric energy meter reading in photovoltaic power generation system, and meter reading under the condition that the lead seal of the main meter of the national grid of the power supply bureau is completely closed and cannot be opened.
