【Abstract】 This paper discusses the method to realize real-time and continual data acquisition and data processing in infinite length data acquisition system. Analyzing the insufficiency of the double buffering technology, this paper discusses how to realize continual and infinite-length data acquisition with ring-like buffer technology, and describes its work mechanism and realization method emphatically . Used in a heart-electrical signal acquisition system, this method has obtained good effect.更多还原
