摘　　要：串口同步采集是工业控制应用的重要环节,为克服由于不准确的数据采集所带来的乘性误差,进而对多串口的同步采集进行了研究。利用VS2005编程环境,设计实现了多串口的上位机数据采集平台,该平台开辟线程对多个串口采取重叠读取方式,实现了对测速系统中大量的串口数据同步读取、保存并实现波形动态显示的功能,满足了智能测速系统的测速算法研究的需要。此平台可以广泛的应用在测速系统之中,也可辅助用于各种工业控制的高级要求。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.
