Synchronous acquisition of serial port is an important part of the speed system,to overcome the data inaccuracies caused by data acquisition of the error,then the synchronization of the multi-serial port collection is studied.In details,under the VS2005 pro-gramming environment,a multi-serial port based data acquisition platform is implemented using a host computer.By opening thread to read varieties of ports with overlapped mode,this platform achieved the function of reading and saving large quantities of serial data syn-chronously and afterwards displaying these dynamic waveforms,therefore satisfied the needs of intelligent speed system for the detecting algorithm.The test shows that the system not only is applied broadly in speed detecting system,but also is assisted in varieties of high-level requirements industrial control field.
