Research on High Disturbance Immunity Technology of Dual Mode Communication Unit in Complex Electromagnetic Environment
With the development of science and technology and the increasing popularity of elec-tronic devices,electromagnetic energy in the environment is becoming more and more dense.In this paper,the interference problem of environmental electromagnetic energy on HPLC+HRF(high-speed carrier+high-speed wireless)dual-mode communication unit of power grid is studied.The electromagnetic environment of the station area where the communication unit is damaged due to strong interference is analyzed,and the noise waveform caused by the communi-cation unit is captured,and the interference signal is suppressed by band-stop filter.At the same time,in order to compensate the insertion loss of band-stop filter,the transmitting and receiving channels of wireless signal are compensated,which ensures the performance of wireless commu-nication.Finally,through the field test,the problem of communication unit damage is elimina-ted.
