Embodiment Construction
[0052] The present invention will be further specifically described below in conjunction with the accompanying drawings.
[0053] Such as Figures 1 to 5 As shown, a detection method for power line two-way power frequency communication includes the following steps:
[0054] 1. Weighted and summed signals to eliminate background signals
[0055]
[0056] Power frequency communication uplink signal detection is to extract the weak current in the background, so the weighted summation is used to cancel the power frequency signal, and IA, IB, IC are the three-phase currents in the distribution network, which can eliminate most of the fundamental waves Influenced by current, at the same time, the signal is enhanced by 1 times;
[0057] 2. Deriving the weighted and summed communication signal
[0058] Such as figure 2As shown in the equivalent circuit schematic diagram of the two-way power frequency communication uplink modulation signal modulation, the uplink signal transmit...
