The Design of Low Voltage Power Line Carrier Communication Channel Testing Device
PowerSline carrier communicationSis widely used inSautomatic meter reading and street lamp controlSetc. Due to the powerSlineSis not aSdedicated communication channel,Sfor electrical equipment,Spower load,Sgrid structureSand other factors, the channelStransmission characteristicsSvaried in time domain and frequency domain, which directly influence the businessScarrying capacity and application effect ofSpowerScommunication products. This paper introduces aSportableSlow voltage power line carrier communicationSchannel testingSdevice, which can realize the online measurement of noise, impedance and attenuation ofSthe power line carrierSchannel, andScan get the variation characteristics of carrier channel through theSreal-timeSanalysis software. The device is of great significance to theStechnology realization and engineering application ofSpowerSline communication products.
