摘　　要：针对多通道串行通信数据中数据丢失和通信波特率自识别的问题,研究了一种多数据流多缓冲乒乓算法存储串行通信数据,解决了帧间隔时间不确定、长度不定长的多通道串行通信数据接收和存储难题。利用微处理器的DMA和串口中断技术,设计了一款多串行通信数据记录器。实验测试表明:应用多串口存储算法的数据记录器能够有效解决串行数据丢失与波特率自识别问题,数据记录器可应用于大容量数据存储。Aiming at the problems of data loss and baud rate identification in multi-channel serial communication data,a multi-stream and multi-buffered Ping-Pong algorithm was proposed to store serial communication data,which solved the problem of receiving and storing multi-channel serial communication data with uncertain frame interval time and variable length.A multi-channel serial communication data storage algorithm was studied,in order to solve the problems of data loss and difficult baud-rate identification for serial communication data.Using DMA(direct memory access)and serial communication interrupting technology of microprocessors,a multi-serial communication data recorder was designed.Tests show that using data recorders with multi-serial storage algorithm can effectively solve the issues of serial data loss and self-identification baud-rate,and the data recorder is suit-able for the application of large capacity.
