Method of shortening strain time of radio locomotive signal

This invention discloses a method for shortening the change time of signals of radio locomotives including: 1, selecting digital transmission broadcast stations with quick transmitting speed and short receive and sending switch to increase the wireless tansmission frequency, 2, altering the control priority of locomotives and quick responding signals based on the change of signals, 3, applying an interlacing technology to reduce information redundant codes and transmission information volume in space as much as possible without changing the transsion error rate, 4, applying variable frame structure to reduce the entire transmitted information volume, 5, altering the control period and length of time slot based on the control to locomotives.
