    • Abstract
  • The model and algorithm of data stream transmission control in the vehicle terminal are put forward.The changing quantity of speed and the changing quantity of direction act as condition of judgment in the algorithm.The judgment criterion is discussed and the equation of data recovery in the monitoring center is proposed.The experimental result shows that the algorithm has an excellent effect on data transmission rate,and the data stream transmission control in vehicle terminal reduces the data transmission rate to only 3.6%.In addition,the recovered data can approach the original GPS trajectories in the monitoring center.
