LabVIEW平台下双缓冲高速串口通信系统的设计与实现

摘要

采用多线程机制、双缓冲和队列技术，基于LabVIEW平台和高速 RS422串口，在高速通信模式下实现数据的实时采集、处理、显示及存储。实际项目应用表明，系统运行稳定，执行效率高，具有良好的可移植性和可扩展性，能较好地完成高速串口通信功能。%High speed serial communication system was developed based on LabVIEW and RS422 communication protocol. Multi threads mechanism,double buffer technique and queue scheduling in LabVIEW were applied for the real time data acquisition and processing,GUI display and database storage.Application result indicates the proposed frame can improve the operation effi-ciency and veracity,expand the program's functions effectively.
