Patent Searching and Data


Title:
DATA COMMUNICATION METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/024251
Kind Code:
A1
Abstract:
The present invention provides a data communication method and system; once it completes sending a to-be-processed data packet, a first terminal begins to measure a first phase difference between a waveform phase difference of a communications carrier signal with a first initial phase difference, and only if the first phase difference is within a threshold range, receives a reply packet; a second terminal completes reception and begins to measure a second phase difference between the waveform phase difference of the communications carrier signal and a second initial phase difference, and only if the second phase difference reaches Δφ, sends a reply packet; the first terminal and second terminal send and receive data simultaneously by means of measuring phase difference, greatly improving the timekeeping accuracy of the two parties; thus it is ensured that the first terminal and second terminal send and receive a reply packet only at a moment of specifically high accuracy, the risk of data received by the first terminal being altered externally during transmission is prevented, and the reliability of the reply packet received by the first terminal is increased.
