Abstract

The invention discloses a data transmission rate control method, and relates to the technical field of network data transmission. The data transmission rate control method comprises the following steps: S1, setting an adjustment time interval of code stream as T; S2, detecting whether the stable time of a current code rate is larger than or equal to T; S3, judging whether the current code rate reaches the maximal code rate; S4, reading a next level code rate from a system code rate configuration table; S5, adding a redundant packet in the current code stream to make the rate of the mixed code stream reach the code rate value of the level in S4; S6, stopping adding the redundant packet, and observing the change of a receiving parameter; S7, if the receiving parameter in S6 is complete, entering the next step; if the receiving parameter in S6 is incomplete, adjusting the time interval T in S1, and repeating S2 to S6; and S8, normally transmitting data, and repeating S1 to S7 after the time interval T. The data transmission rate control method disclosed by the invention has the advantages that the method can be used for effectively improving the data transmission efficiency under an effective bandwidth volume.

Description

technical field [0001] The invention relates to the technical field of network data transmission, in particular to a data transmission rate control method. Background technique [0002] In a remote maintenance system, the main active area of ​​the service object is on the sea surface. Compared with the land-based remote system, the data of the land-sea system is transmitted through the satellite channel, and the bandwidth capacity is limited. The security technology adopted by the system further occupies the normal data transmission channel space, resulting in low efficiency of remote maintenance data transmission. The land-based remote system can solve the problem of data transmission speed by increasing the bandwidth capacity. Under the current conditions, this method is the simplest and most effective, but the cost of use is relatively high. Moreover, this method is not applicable in the land-sea mode. Aside from the cost factor, the satellite channel capacity is limited...
