摘要
所提出的智能型电源线资料传输系统,是以电源线作为信号传输的系统,以HOLTEK MCU单片机作为控制单元,控制载波及信号的频率,以变化的载波及信号的频率先传送的测试信号,后再由收到的信号品质评估最佳的载波及信号的频率,以此频率传送的摇手信号,待另一电路回应信号后,便以此频率传送及接收资料。
Our proposed intelligent power line data transmission system,based on the power line as a signal transmission system to HOLTEK MCU microcontroller as control unit,control carrier and signal frequency to change the frequency of the carrier and the signal first transmitted test signal,and then assess the quality of the signal received by the best carrier and signal frequencies,as frequency signals transmitted waving,until the response signal of another circuit,this frequency will transmit and receive data.
