Patent ID: 11860200
Assignee: TENDYRON CORPORATION
Field: Telecommunications (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 9:
10. A power line data transmitting device, comprising:
the zero crossing point signal output apparatus of claim 7; and
a data outputting module configured to, subsequent to receiving the zero crossing point signals with the interval being the zero crossing point signal output interval which are continuously output by the outputting module, determine a 1st zero crossing point time t based on the zero crossing point signals, and determine a start time of transmitting a synchronization signal of a data packet to be transmitted based on the 1st zero crossing point time, wherein the start time of transmitting the synchronization signal of the data packet to be transmitted is t+t1, t+t1 is earlier than a 2nd zero crossing point time t+T, t+T is comprised in a time period from a time point of transmitting a first synchronization bit signal to a time point of transmitting a last synchronization bit signal, and t1 is a first predetermined fixed value; and sequentially transmit data bit signals of the data packet to be transmitted.
