Reliability control method and system based on unidirectional data transmission

Abstract

The invention discloses a reliability control method and system based on unidirectional data transmission, and the system is characterized in that an acquisition unit, a transmitting unit, a receivingunit and an analysis unit are in unidirectional communication connection in sequence, and the analysis unit is in communication connection with the transmitting unit. The acquisition unit is used foracquiring actual service scene data and network flow; the transmitting unit is used for packaging and sending the data acquired by the acquisition unit; the receiving unit is used for receiving the data packet sent by the sending unit, collecting system state data according to millisecond precision and sending the collected system state data to the analysis unit, and the analysis unit is used foranalyzing the received system state data and generating a time sequence database according to the system state data. By combining the system state of the data packet loss rate acquired and analyzed in the actual data transmission process and the mode of intelligently and dynamically adjusting the sending speed, it is ensured that data can be accurately received, and meanwhile existing hardware can be better utilized to achieve one-way transmission of balance performance and reliability.

Description

technical field [0001] The invention relates to the technical field of industrial data transmission. Specifically, it is a reliability control method and system based on one-way data transmission. Background technique [0002] At present, most of the one-way reliable transmission without feedback is based on the UDP transmission scheme, that is, when it is impossible to confirm whether the data is received accurately, most of them use multiple redundant data transmissions to ensure the correctness of the data. In most cases of system data loss, the system processing is not timely enough, or the system load is too high. The shortcomings brought about by multiple redundant data transmissions will lead to a decrease in network bandwidth. In scenarios with high performance requirements, hardware supplements are required to compensate for the performance loss. Contents of the invention [0003] For this reason, the technical problem to be solved by the present invention is to...
