| Abstract: | The features of multi-thread technology are introduced,and the methods of the thread synchronization between the multiple threads are analyzed.Due to the advantages of Delphi in database operations,a parallel program is designed to download simultaneously data into several devices in terms of Delphi multi-thread technology.Especially,the methods of transmission and receival are described according to the TNMUDP control.As a result of using the multithreading technology,the transmission efficiency is improved remarkably,at the same time,the transport delay time is reduced.In addition,the detection and retransmission mechanisms are provided to guarantee the reliability of data download because the UDP protocol is adopted as the communication protocol. |
