Research of Impact about Harmonic Interference on Acquisition Unit Operation

As a key equipment to complete the communication between energy meter and concentrator, theacquisition unit plays a key role in the construction of information collection system. Based on the carriercommunication theory and harmonic generation mechanism of switching power supply, this paper analyzed theharmonic of the switching power supply, its causes and impact on the acquisition unit carrier communication andgave out solutions, which greatly reduces the impact of high frequency harmonics on the acquisition unit.
