A method and system for improving data transmission reliability in a unidirectional transmission system

Abstract

This invention discloses a method and system for improving the reliability of data transmission in a unidirectional transmission system. The method includes: using a network gateway's receiving system to acquire service data to be transmitted based on the TCP transmission protocol, simultaneously assigning data numbers and caching the data; using a proprietary protocol to encapsulate the cached service data to generate transmission data, and writing the transmission data into a unidirectional data transmission channel; using the network gateway's sending system to receive the transmission data and insert the transmission data into a first-level data buffer sequence to obtain output data; selectively sending the output data or inserting it into a second-level data buffer sequence based on a preset order-preserving algorithm, and sending all output data in an ordered manner according to the expected number. By sending the transmission data to the data receiving server using the order-preserving algorithm, the order of the service data received by the server remains consistent with that uploaded by the device, avoiding data disorder and improving the stability of service data upload.
