Title:
DATA COMMUNICATION METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/024241
Kind Code:
A1
Abstract:
Provided in the present invention are a data communication method and system; when a first terminal finishes sending data packets to be processed, starting to record the number of first terminal pulses of the communication carrier signal sent by the first terminal, and only receiving response data packets when the number of first terminal pulses reaches a threshold number of pulses N; when a second terminal finishes receiving same, starting to record the number of second terminal pulses of the communication carrier signal received by the second terminal, and only sending response data packets when the number of second terminal pulses reaches N; the first terminal and the second terminal implement simultaneous sending and receiving of data on the basis of detecting the number of pulses, greatly increasing the timing accuracy of both sides and thereby ensuring that the first terminal and the second terminal only send and receive response data packets at a specified high accuracy time, preventing the risk of external tampering to the data packets received by the first terminal during the transmission process and increasing the reliability of the response data packets received by the first terminal.
