Problems solved by technology
[0003] However, in the actual power carrier communication, due to the noise interference of the power line itself, large load changes and other problems, as well as the serious signal attenuation, crosstalk, synchronization and other phenomena during carrier signal communication, the reliability and stability of carrier communication have dropped significantly. And it is difficult to realize the cross-phase communication of carrier communication

The embodiment of the invention discloses a carrier cross-phase communication method and device. The carrier cross-phase communication method includes: determining the phase of the alternating current transmitted on the first phase line; based on the phase of the alternating current transmitted on the first phase line, sending the first The phase line continuously sends the same carrier signal, wherein the number of preset phases is equal to an integer multiple of 3, and the preset phases include at least three of 0°, 60°, 120°, 180°, 240° and 300°; The carrier signal is received from the neutral line, the second phase line or the third phase line of the alternating current transmission, and the high reliability and high stability cross-phase transmission of the carrier signal is realized.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of power carrier communication, and in particular, to a carrier cross-phase communication method and device. Background technique [0002] Power carrier communication technology uses power lines for data transmission. Power carrier communication technology is widely used in the construction of power information platforms and systems due to its outstanding advantages in reliability and economy. [0003] However, in the actual power carrier communication, due to the noise interference of the power line itself, large load changes and other problems, as well as the serious signal attenuation, crosstalk, synchronization and other phenomena during carrier signal communication, the reliability and stability of carrier communication have dropped significantly. And it is difficult to realize cross-phase communication of carrier communication. Contents of the invention [0004] Embodiments of ...
