| Abstract: | In view of the reliability and the efficiency of the remote control systems for Electric Power Equipment, a remote control system is proposed in which the control information interacts by low voltage power network communication. Low voltage power network is used as the channel for control information of Electric Power Equipment. The MSK modulation and demodulation technology that is seasoned with the channel characteristics of low voltage power network were selected, while the theory of MSK is analyzed,and ... |
