一种改进的基于LabVIEW的DAQ采集系统设计
An Improved Design of Data Acquisition System Based on LabVIEW
摘要
Abstract
In present,data acquisition(DAQ)systems based on LabVIEW are widely used in signal acquisition and subse?quent processing. However,the simple examples are given for existing DAQ systems,and are not combined with LabVIEW's exist?ing programming architectures,and most of the existing programs are developed for specific data acquisition tasks with poor scalabil?ity. There is also no logically effective distinction between signal acquisition control and the data processing. Therefore,they are not suitable for large-scale DAQ system developments. Aiming at this problem,a DAQ system architecture based on state machine, event structure and queue message is designed. This design combines the advantages of state machine,event structure and queue message to realize the distinction between the separation of interface signal acquisition control and data processing, which has good scalability. The test results show that the design can effectively realize the data acquisition and processing process,and is suitable for the development and design of large-scale signal acquisition and processing systems.关键词
